Abstract
Description
[0001] The present invention relates to the technical field of textile-based filter materials, in particular surface filter materials, and preferably textile-based protective filter materials, which can be used, for example, in the military or civilian sector, such as for the production of protective equipment and protective clothing, in particular with a protective function against chemical and / or biological and / or nuclear or radioactive pollutants, as well as for various technical filter applications or the like.
[0002] Against this background, the present invention relates in particular to an ABC protective filter material (CBRN protective filter material, synonymously also referred to as protective filter material), preferably textile ABC or CBRN protective filter material (here synonymously also referred to as protective filter material or protective and / or surface filter material), preferably for use in a textile ABC protective clothing item (CBRN protective clothing item), preferably with a protective function against chemical or biological or nuclear (radioactive) pollutants, wherein the ABC protective filter material according to the invention has a high or improved (further) tear resistance (with ABC = atomic, biological and chemical and with CBRN = chemical, biological, radioactive and nuclear, the terms ABC on the one hand and CBRN on the other hand being used synonymously in the context of the present invention). The protective filter material according to the invention is characterized in particular by a high orimproved (further) tear resistance (preferably tear resistance).
[0003] In this context, the present invention relates to the technical field of ABC or CBRN protective clothing, as it can be used in particular for military purposes or for civilian purposes, for example in the field of hazard prevention, firefighting or in the field of disaster control or the like. Furthermore, the present invention also relates to the technical field of ABC or CBRN filters or technical filter applications or filter units, which can be used, for example, for the treatment or purification of fluid media (i.e., gaseous or liquid media, in particular gaseous media such as air or the like), for example in the context of the treatment or processing of room or ambient air or breathing air).
[0004] Furthermore, the present invention also relates to the use of floats (floats) and / or of multiple, in particular double (double), inserted warp threads or of multiple, in particular double (double) inserted weft threads in a (textile) fabric used as a textile carrier layer for increasing or improving the (propagation) tear resistance (preferably tear propagation resistance) of a protective filter material which has a corresponding fabric or a corresponding carrier layer.
[0005] In addition, the present invention also relates to the use of a special carrier layer or a carrier material for increasing the (propagation) tear resistance (preferably tear resistance) of a textile fabric or protective filter material and / or related protective equipment or protective articles as well as filters or filter materials which comprise the protective filter material with the corresponding carrier layer or the carrier material.
[0006] Furthermore, the present invention also relates to specific uses of the protective filter material according to the invention, namely in particular for the production of protective equipment or protective articles, in particular protective clothing, as well as for the production of filters and filter materials of all kinds. The present invention also relates to protective equipment and protective articles, in particular protective clothing, and filters and filter materials which comprise the protective filter material according to the invention or which are produced using the protective filter material according to the invention.
[0007] In general, protective filter materials or surface filter materials, which usually have textile-based components or textile functional and carrier materials, are subject to high demands with regard to their specific functional properties for NBC or CBRN protection. This also applies to mechanical stability, resilience, and durability. Specifically, the high demands placed on such materials include providing efficient, reliable, and / or long-lasting protection or related filter properties against chemical, biological, nuclear, and radioactive pollutants or toxins, even under adverse or challenging operating conditions. This particularly applies to protection based on particle or aerosol filter properties as well as adsorptive properties, especially against chemical, biological, nuclear, or radioactive pollutants or toxins.The high requirements for protection against harmful or toxic substances of the aforementioned type inevitably arise due to the exceptionally high health risk to the wearer when exposed to or affected by them.
[0008] In the state of the art, textile protective filter materials are used, for example, to provide NBC or CBRN protective suits in the military sector (i.e. for military personnel or soldiers, often as additional protection in defense or combat operations) but also in the civilian sector or civil protection sector (i.e. for personnel involved in disaster or fire operations, such as firefighters). Another area of application is industrial applications, for example in the chemical industry, for example in the handling or control of toxic industrial chemicals (TICs). In general, corresponding protective filter materials in the form of protective clothing or suits ensure additional protection against exposure to human toxicological agents.Substances such as those that may be released in accidents in the chemical industry or nuclear facilities, for example in connection with or as a result of natural disasters.
[0009] Against this background, one of the technical challenges with regard to the provision of suitable protective filter materials is to realise diametrically opposed or opposing product properties in one and the same material, for example with regard to ensuring or providing high mechanical resistance or stability (load-bearing capacity) as well as high protection or filtering performance with regard to toxins or harmful substances on the one hand, while at the same time ensuring high air permeability of the underlying materials on the other. A major difficulty is also to be seen in providing suitable protective filter materials which have high mechanical resistance or stability (load-bearing capacity) or stability in the face of mechanical stress, also against the background of the aforementioned functionalities, namely efficient protection against harmful substances orToxic substances, even under unfavourable conditions or high mechanical requirements, in order to ensure a high level of application and operational safety.
[0010] Special product properties, such as high protection or filtering performance against harmful or toxic substances, combined with high mechanical resistance or stability and high air permeability, are of key advantage or even necessary in protective clothing, for example, to ensure the provided protective function even under high mechanical stress or strain. Such product properties are also of great importance in technical filter applications. In particular, the underlying materials must also offer high application and operational safety and be easy to handle.
[0011] In this context, a major requirement is to provide high levels of protection, even under high mechanical stress, against chemical, biological, or radioactive pollutants or toxins, which may be present, for example, in the form of aerosols, gases, droplets, contaminated particles, or the like, and which also exhibit a wide range of different physicochemical properties. Accordingly, the underlying protective filter materials and the corresponding protective clothing should also offer a correspondingly broad range of protection.
[0012] A particular key challenge is to provide suitable protective filter materials and protective clothing which have a high level of mechanical stability and resistance and therefore a high level of durability and service life. This requirement is of crucial importance as the corresponding protective (filter) materials are often exposed to high levels of mechanical stress during use. Friction, tensile or compressive stress, for example from wearing heavy equipment or the like, or contact with sharp-edged and / or abrasive objects or surfaces can lead to the destruction of the protective (filter) material, for example as a result of cracks or cuts. Mechanical impact, for example from explosion-related splinters or fragments or from projectiles orballistic bodies or the like lead to high mechanical stress or impairment of the material.
[0013] This can sometimes cause permanent damage to the material, for example, through (further) tearing. Such damage often leads to disintegration, or at least to a deterioration of the protective function against incoming harmful or toxic substances, as the barrier function (filter function) of the material is reduced overall, allowing harmful or toxic substances to penetrate through the material or through damaged areas.
[0014] As a result of mechanical damage, the protective filter material may partially or even completely lose the intended protective performance or function, especially if several or even all material layers are damaged in the case of a multi-layered protective filter material.
[0015] In the case of protective clothing, this can lead to direct and generally undesirable exposure of the wearer or user, or in the case of filters or filter materials, to a breakthrough of harmful or toxic substances, associated with the risk of lasting and sometimes even fatal health effects. It is also important to note that even small amounts of toxic substances can often lead to lasting health impairments or subsequent effects for persons exposed to or exposed to such substances.
[0016] In addition, harmful or toxic substances often exist in the form of finely divided or fine-particulate aerosols or in the form of pollutant particles or gases present in the (ambient) air, which generally have a high penetration potential. Therefore, ensuring a permanent protective function with an intact protective sheath or filter function in the case of protective clothing, even under or after high mechanical stress, is essential or even indispensable.
[0017] Consequently, there is a high overall demand for the provision of protective filter materials which, in addition to ensuring a high level of protection against harmful or toxic substances, also have a correspondingly high level of mechanical stability or mechanical resistance, particularly against external forces or the like.
[0018] This is particularly true insofar as persons on military deployment, such as soldiers, as well as persons working in disaster relief or firefighting, are exposed to the permanent risk of contamination with chemical, biological or radioactive pollutants or toxic substances, which often exists throughout the entire deployment period. In addition to high physical strain, there is also high mechanical stress on the protective equipment concerned throughout the entire deployment period.
[0019] In the military sector in particular, military personnel, such as soldiers, move around in conflict-laden environments with high physical exertion and are exposed to high levels of danger, which requires a high level of usability and suitability for the underlying protective clothing. It is also important to note that in the event of mechanical failure of the protective clothing, for example as a result of (further) tearing, the protective barrier against the penetration of toxic substances is interrupted, accompanied by a dissolution of the protective barrier to the user (wearer) or operator of such protective clothing. For example, chemical skin warfare agents such as sulfur mustard and nitrogen mustard can affect the user (wearer), for example, penetrating the skin, sometimes resulting in a lethal effect on the wearer.
[0020] In the civil and industrial sectors, a high level of protection is equally essential due to the mechanical integrity of protective clothing, particularly with regard to avoiding direct contact with toxic industrial chemicals or the like, even in cases of high physical strain or mechanical stress on protective clothing.
[0021] The same applies to filters and filter systems based on such protective filter materials, where ensuring physical integrity even under high mechanical stress is crucial to ensuring the protective function, particularly with regard to preventing the formation and continuation or spread of cracks or the like.
[0022] State-of-the-art protective filter materials or surface filter materials, which often have simply designed textile carrier materials or layers for adsorbents or filter layers, for example, often cannot reliably meet the high requirements for mechanical stability, particularly with regard to their (tearing) behavior. As a result, such state-of-the-art materials do not provide optimal, reliable, and lasting protection against the effects of harmful or toxic substances, particularly under extreme conditions, such as protective clothing in military use or in hazard prevention or disaster control. This particularly applies to the lack of resistance to high mechanical stress or damage to the material, especially with regard to tearing or tearing propagation of the material.
[0023] Given that protective suits, for example, must meet the requirements of long periods of wear or use, even under adverse conditions, this immediately results in the demand for appropriate protective filter materials or surface filter materials with high mechanical resistance and stability.
[0024] With regard to ensuring an efficient and long-lasting protective function even under or after mechanical stress, the (propagation) tear strength (preferably tear resistance or resistance) and thus in particular the resistance of a protective filter material to forceful (propagation) tearing is of great importance. This is especially true because, if the (propagation) tear strength is insufficient, cracks that occur under the influence of force or tearing can often extend over large areas of the protective (filter) material. Complete and irreparable damage to the underlying protective filter material is then often unavoidable. In particular, this can be the case with corresponding protective filter materials with low mechanical resistance orStability often behaves in such a way that after initial and initially only minor damage to the material, even small forces lead to undesirable (further) tearing and thus to lasting damage to the material, accompanied by a total loss of the protective function against harmful or toxic substances.
[0025] The development of large cracks in a protective filter material that have a lasting or irreversible impact on its function often results from what are sometimes only minor initial damages, such as small tears or incisions or pinpoint punctures. As a result of insufficient (further) tear resistance, large cracks can develop with only minor stress or the application of force, often starting from small or minor (initial) damage. Such cracks can spread quickly and over a large area of the protective filter material, often affecting the entire transverse extent or thickness of the protective filter material and across several or even all of the material layers. Such damage leads to a far-reaching and frequently complete loss of the protective function, since damage or incisions hitting the protective filter material cannot be completely redirected.Toxic substances can penetrate through the damage or tear almost unhindered. It is therefore also important that protective filter materials exhibit high resistance to mechanical forces, particularly with regard to high (further) tear resistance and resilience after initial damage.
[0026] High (further) tear resistance ensures that the integrity and soundness of a protective filter material is maintained even after initial (minor) damage (e.g., after small tears), even when high forces are applied to the material. This minimizes the formation of penetration points for harmful or toxic substances and fundamentally maintains or preserves the overall protective function. Thus, the provided (further) tear resistance also represents a decisive factor in determining the quality of a protective filter material.
[0027] In general, the (further) tearing of a textile-based material, such as a protective or surface filter material, can be understood as the successive failure of threads or yarns or groups of threads or yarns along a line through the textile material, for example in the form of a carrier layer or of a protective filter material as a whole with such a carrier layer. In the case of a textile material in the form of a woven fabric with a warp and weft thread system forming the fabric, this particularly involves the failure or tearing of adjacent warp threads or groups forming a group (especially when force is applied in the weft direction) or adjacent weft threads or groups forming a group, especially when force is applied in the warp direction.
[0028] Against this background, the (further) tearing differs from the tearing force or tensile strength as such, because in contrast to the tearing force, the maximum force of a sum of threads until breakage is measured.
[0029] For technical textile materials, such as protective filter materials, tearing is one of the most common failure modes. Tearing is therefore also used as a direct assessment of usability or a quality characteristic, particularly for textile materials used in the military sector. In general, products with low tear resistance or inadequate tear resistance can therefore pose an excessive risk to the wearer or user of protective clothing made from them. Against this background, the tear resistance of a protective or surface filter material is an important property that characterizes its overall protective function, for example, for protective clothing in the military and civilian sectors for hazard prevention.
[0030] In this respect, the selection and coordination of the components underlying a protective filter material also plays a key role in determining the stability of the protective suits or filters manufactured from it. The material in question should possess high mechanical stability overall, particularly in order to withstand severe mechanical stress, such as that caused by tearing or tear propagation forces acting on the material, thereby ensuring the integrity and integrity of the protective filter material and thus overall application and operational safety.In the case of multi-layer protective filter materials, a carrier layer, such as that used for attaching adsorption materials such as particulate activated carbon or flat filter materials, also plays a crucial role, since such carrier layers, as a textile base structure, have a decisive influence on the mechanical stability of the multi-layer protective filter material as a whole.
[0031] In the field of protective clothing for NBC or CBRN protection, for example in the form of protective suits or similar, as used, for example, in the military but also civilian sectors, air- and water vapor-impermeable materials or protective materials are known in the prior art, which are generally designed with a barrier or rubber layer impermeable to harmful or toxic substances. In addition to being only slightly comfortable to wear due to a lack of air permeability and insufficient flexibility, such materials often lack optimal mechanical resistance, including with regard to the (further) tearing behavior of such materials. The use of flat, impermeable layers is particularly associated with the fact that, in general, no further structures are present to inhibit or prevent crack formation.Where coatings or similar materials are used to create the impermeable properties of such materials, these often result in associated textile support structures or layers not exhibiting high resistance to (further) tearing due to the fixation of the forming thread or yarn components. This means that even minor mechanical stress on the material, for example, caused by previous damage, can lead to small tears or perforations, sometimes resulting in large tears, accompanied by a permanent loss of the protective function, which renders the material unusable. Due to the lack of air permeability, such materials are also unsuitable for technical filter applications or similar.
[0032] Furthermore, air-permeable or permeable functional protective or surface filter materials are known in the prior art, which are generally equipped with an adsorption filter layer, particularly based on activated carbon, or a mechanical filter layer to ensure protection against harmful or toxic substances. Due to the fundamentally air-permeable design of such systems, such materials are suitable not only for the provision of protective clothing or protective suits, but also for technical filter applications. Due to the increased exchange of air and water or moisture, protective clothing made from such materials also offers improved wearer comfort, particularly with regard to reducing heat build-up, while fundamentally providing good protection against harmful or toxic substances.
[0033] The underlying protective filter material is generally in the form of a laminate with a multi-layer structure, in which, for example, a sorption-capable material, such as activated carbon, is incorporated or integrated into a composite material based on a carrier material or layer and a cover material. However, such filter materials do not always exhibit optimal or generally improvable properties in terms of their mechanical stability, including their (further) tear behavior.
[0034] In particular, such protective filter materials lack any further and targeted mechanical stabilization or optimization with regard to their (tear-propagation) behavior. Furthermore, such materials often exhibit a rigid or inflexible structure due to the generally areal bonding of the individual layers to form the laminate or composite, for example by means of adhesive bonding, which impairs their (tear-propagation) resistance. In particular, protective or surface filter materials are subject to a sometimes pronounced transfer of forces (e.g., in the form of (tear-propagation) forces) that may occur during mechanical loading, for example, to the carrier material or layer, which can lead to easy tearing.
[0035] The adhesive application often provided for in the prior art sometimes leads – in addition to excessive stiffening of the material – to excessive immobilization or fixation of, for example, threads or yarns forming a textile layer of the protective filter material, so that their mobility can be severely restricted. As a result, the flexibility of the threads or yarns is often not sufficient, for example in the event of (further) tearing stress, which reduces the (further) tear resistance of the material in question.
[0036] This is particularly true given that the prior art does not contain any specific, targeted measures to increase resistance to mechanical impacts, including with regard to ensuring high tear resistance, which is of essential importance since the formation of tears in particular leads to a significant reduction in the level of protection against toxic or health-endangering substances. In addition, the prior art uses conventional textile fabrics for the textile carrier layers. In this regard, no further measures to achieve high or improved tear resistance are available. In addition, the adhesive applied to bond the layers in the prior art often leads to excessive blocking or interference with the threads or strands forming the carrier material or layer.Yarn systems so that their mobility is reduced, with the result that the (further) tearing behavior is reduced.
[0037] In view of the above statements, the protective or surface filter materials provided in the state of the art for protective clothing or technical filters or filter systems are sometimes not optimally coordinated or do not provide for increased stability or mechanical resilience, in particular with regard to ensuring high (further) tear resistance.
[0038] The lamination of individual layers to form a textile protective or surface filter material with the corresponding carrier or layer materials, as is common in the prior art, often results in reduced flexibility or pliability of the resulting filter material, which can lead to excessive formation of kinks or the like under force. This can result in undesirable delamination of the layers, accompanied by a reduction in the protective function provided. The formation of kinks can also reduce the (further) tearing behavior of the filter material overall, as this can lead to mechanical weak points. In particular, undesirable delamination can occur in the area of kinks, which negatively impacts the integrity and mechanical stability of the protective or surface filter material overall.Due to the reduced flexibility or pliability of protective or surface filter materials known in the prior art, optimal wearing comfort, particularly with regard to providing a high level of conformability, is often not guaranteed when used in protective clothing. In this context, the haptic properties of such materials are also not always satisfactory.
[0039] In particular, no specific measures are described to develop high or optimized (further) tear resistance.
[0040] EP 2 026 884 A2 and WO 2007 / 071835 A2 and US 2009 / 0093178 A1, respectively, belonging to the same patent family, describe a composite textile material for CBRN applications, comprising a first nonwoven material suitable for forming a physical barrier to the penetration of microorganisms, and a second material suitable for capturing the microorganisms trapped by the first material through absorption and / or adsorption. The composite material may comprise a textile carrier material suitable for supporting the second material. In particular, a concept is pursued that focuses significantly on the filter properties of the underlying composite textile material as such.
[0041] Overall, the above statements show that the provision of high mechanical stability and resistance, in particular with regard to the (further) tear resistance and resistance, of protective and surface filter materials is of great importance with regard to their use in or as protective clothing.
[0042] This also applies to the use of protective filter materials in the technical field of providing technical filters or filter systems for the purification of fluid media. Technical filters and filter systems are often exposed to high mechanical stress, particularly with regard to their use in the military or civilian sectors, e.g., for disaster relief. Furthermore, handling such filters or filter systems (which often occurs under adverse conditions in military or disaster relief operations) can result in high levels of force, which also applies to their use in technical applications.
[0043] Overall, there is a high demand in the state of the art for protective filter materials with particle or aerosol filter properties or with adsorptive properties against pollutants or toxic substances, which exhibit improved resistance to mechanical (force) influences, particularly with regard to providing improved (further) tear resistance. There is also a high demand for protective or surface filter materials with correspondingly high durability and, subsequently, good wearability in the case of protective clothing, as well as high purification efficiency while ensuring high throughputs of media to be purified in the case of technical filters or filter systems.
[0044] Against this background, it is an object of the present invention to provide a protective filter material, in particular textile protective filter material, which is suitable for use in the military and civilian sectors, for example for the production of protective suits or the like, as well as for the field of technical filter applications, such as for gas or air filters, wherein the previously described disadvantages of the prior art are to be at least largely avoided or at least mitigated.
[0045] A further object of the present invention is, in particular, to provide a protective or surface filter material which has a high mechanical stability or mechanical resistance which is improved compared to the prior art, in particular with regard to the tear resistance of the protective or surface filter material, preferably (propagation) tear resistance (preferably tear propagation resistance). In this case, such a protective or surface filter material should also have or retain the functionality with regard to providing a high level of protection against chemical or biological or radioactive or nuclear pollutants or toxins. In particular, such a material should be suitable overall for a large number of applications, in particular in the textile or clothing sector, for example for the production of protective equipment orClothing with a protective function against corresponding pollutants or toxins. Furthermore, the protective or surface filter material should be equally suitable for the production of filters or filter systems and thus also for technical filter applications.
[0046] A further object of the present invention is to provide a protective or surface filter material or textile protective or surface filter material which, while simultaneously exhibiting high or improved mechanical resistance, in particular improved (further) tear resistance, also has improved application and handling properties. In this context, a particular object of the present invention is to provide a corresponding protective or surface filter material which ensures a high level of wearing comfort, particularly with regard to its use in or as protective clothing or the like. In this context, the aim is in particular to provide high flexibility or pliability and conformability while simultaneously exhibiting high air or water vapor permeability.
[0047] In particular, the present invention aims to provide a special protective filter material that offers improved mechanical strength, particularly with regard to (further) tear resistance, while at the same time not negatively impacting other material-specific parameters, such as air permeability and the seam or tensile strength of the underlying materials. In particular, high dimensional stability is also to be achieved. Furthermore, an overall optimized basis weight is to be provided.
[0048] Furthermore, another object of the present invention is to provide a protective filter material, namely based on or in the form of a textile protective filter material, which is generally relatively easy to manufacture, while also reducing the use of relevant components or materials, for example, with regard to the layer structure. The sustainability and cost-benefit ratio of such a material are also to be optimized.
[0049] The present invention therefore aims to provide a textile protective or surface filter material for numerous applications and uses, which exhibits high durability and mechanical stability and resistance, particularly with regard to tear and tear propagation resistance, so that a high level of protection against harmful or toxic substances is guaranteed even under adverse conditions, such as during or after high mechanical (force) stress. At the same time, the material should also exhibit high air and water vapor permeability while maintaining high flexibility and pliability.
[0050] To achieve the above-described problem, the present invention thus proposes - according to a first aspect of the present invention - an ABC protective filter material (in particular a textile ABC protective filter material), preferably for use in a textile ABC protective clothing item, in particular an ABC protective filter material with high or improved (propagation) tear resistance (preferably tear resistance), and in particular an air-permeable and water vapor-permeable textile ABC protective filter material with a protective function against harmful or toxic substances and preferably with high or improved (propagation) tear resistance (preferably tear resistance) according to claim 1; advantageous developments and embodiments of this aspect of the invention are the subject of the corresponding auxiliary and dependent claims.

[0065] in particular wherein the floats in the warp direction each extend over at least two weft threads and / or span them in each case and / or in particular wherein the floats in the weft direction each extend over at least two warp threads and / or span them in each case; and / or, preferably and, wherein a part of the warp threads is drawn in multiple times, in particular twice (double) (ie a part of the warp threads is present and / or formed with multiple, in particular double, (thread) drawing in) and / or a part of the weft threads is inserted multiple times, in particular twice (double) (ie a part of the weft threads is present and / or formed with multiple, in particular double, (thread) insertion), preferably wherein a part of the warp threads is drawn in multiple times, in particular twice (double) and a part of the weft threads is inserted multiple times, in particular twice (double).
[0066] The fabric used as the textile carrier layer thus has very specific or specifically adjusted floats of the aforementioned type. According to the invention, it is particularly provided that the fabric does not have a plain weave and / or is free of a plain weave. In particular, the fabric is not designed as a plain weave. As explained in more detail below, the fabric used as the textile carrier layer can, within the scope of the present invention, be in particular a ripstop fabric with a twill weave.
[0067] With regard to the present invention, the applicant has surprisingly discovered that, through the targeted and purposeful technical measure according to the invention, according to which the textile carrier layer underlying the protective filter material according to the invention is designed in the form of a special woven fabric, particularly with regard to the targeted use of floats and / or multiple, in particular double, drawn-in warp threads or weft threads inserted in this way (which are present in each case alongside singly drawn-in warp threads or singly drawn-in weft threads), the mechanical stability or durability of the protective filter material as a whole can be further increased or improved, particularly with regard to its resilience with regard to (propagation) tear behavior. The protective filter material according to the invention thus exhibits improved (propagation) tear resistance or strength.
[0068] As explained in more detail below, the mechanical resistance, in particular the (further) tear resistance, of the protective filter material according to the invention can be further and significantly increased by further targeted technical measures, in particular by a specially adapted or designed adhesive application for bonding the carrier layer to the other layers, in particular to the further provided protective layer, which, for example, can be based on adsorptive components or which can have a particle or aerosol filter function. Furthermore, within the scope of the inventive concept, special yarns can be used, which lead to further stabilization of the fabric used as the carrier layer, with a positive influence on the (further) tear resistance. Reference can also be made to the following explanations in this regard.
[0069] As a result of the use of a specially designed fabric as a textile carrier layer for the protective filter material according to the invention, according to which the fabric has a special arrangement of warp threads and weft threads forming the fabric, on the one hand based on floats (floats) in the warp direction or in the weft direction and on the other hand based on a special thread arrangement, according to which a part of the warp threads or the weft threads is drawn or inserted into the fabric several times, in particular twice (double), a significant improvement in the (further) tear behavior with an increase in the (further) tear resistance is achieved, in particular in both the warp and weft directions.
[0070] It is also quite surprising that other material-specific properties, such as air permeability, seam and tensile strength, bendability and flexibility, are retained or even improved to the same extent.
[0071] According to the invention, as a result of the special design of the textile carrier layer as a woven fabric with floats and multiple, in particular double (double) drawn-in warp or weft threads, a protective filter material with improved (tear-propagation) behavior and increased (tear-propagation) strength is provided overall. This provides greater mechanical resistance and thus improved protection against harmful or toxic substances even under or after strong mechanical stress, since the protective filter material is not destroyed even under high (tear-propagation) force and is overall more resistant. Due to the high mechanical resilience, particularly with regard to the excellent (tear-propagation) behavior, the formation and further development or progression of tears is significantly reduced or prevented.
[0072] The protective filter material according to the invention is not destroyed even under high mechanical stress and thus maintains its integrity, thus maintaining its protective function or providing a more resistant protective function against harmful and toxic substances (warfare agents). In particular, the formation of larger penetration points for harmful or toxic substances can be prevented due to the high (further) tear resistance, thus providing an extremely high-performance and durable protective filter material according to the invention.
[0073] In the context of the present invention, the situation is particularly such that - without wishing to rely on or be limited to this theory - the respective warp threads or weft threads have a relatively high yarn mobility due to the presence of floats, so that they are pushed together or bundled upon exposure to a corresponding tearing or tear propagation stress and are thus, so to speak, deposited against one another, forming a mechanical reinforcement. This effect can be vividly described as the "bundle effect" or "cable effect," according to which, as a result of the floats, warp threads or weft threads are pushed together or deposited against one another under the influence of a forceful tearing or tear propagation stress, particularly in the tear area or tear triangle, thus forming a bundle.This results in a kind of local reinforcement of the material in the tear area, especially in the tear triangle due to the bundling effect, which leads to increased tear or tear propagation resistance, since a yarn or thread bundle is created when subjected to (further) tearing stress, accompanied by increased resistance when subjected to tear propagation stress.
[0074] Likewise, without wishing to rely on or be limited to this theory, within the scope of the present invention, in the event of a (further) tearing force acting in the warp direction, the weft threads running transversely thereto are displaced over the warp yarns as a result of the floats and, in particular, in the tearing area or tear triangle, form a yarn or thread bundle, which makes (further) tearing significantly more difficult. In a corresponding manner, the invention behaves in particular in such a way that when a (further) tearing force acts in the weft direction, the warp yarns are, as it were, displaced over the weft yarns as a result of the floats and, in the tearing area or tear triangle, form a corresponding reinforcement by yarn or thread bundling. This also counteracts (further) tearing.
[0075] The (further) tear resistance of the protective filter material according to the invention as a whole or of the underlying carrier layer in the form of the fabric is further increased by the fact that, according to the invention, the fabric, as previously stated, can contain multiple, in particular double, inserted warp threads and / or multiple, in particular double, inserted weft threads, in addition to or in addition to singly inserted warp threads or singly inserted weft threads. The multiple, in particular double, inserted warp threads or inserted weft threads are accompanied by a further reinforcement of the underlying carrier layer, particularly in synergistic interaction with the at least partially floating warp or weft threads.
[0076] The multiple, particularly double, warp threads or the correspondingly inserted weft threads represent, so to speak, additional reinforcement in the fabric and thus additional mechanical resistance to (further) tearing, so that the (further) tear resistance is further increased. In particular, the multiple, particularly double, warp threads or the multiple inserted weft threads can also lead to a reinforcement of the carrier layer as part of the aforementioned bundling effect. Floats, if present, even for the multiple, particularly double, warp or weft threads, can also increase their mobility in the fabric. This particularly promotes the desired bundling of the underlying yarns or threads in the event of (further) tearing.
[0077] The multiple, in particular double or doubly inserted warp threads or correspondingly inserted weft threads represent - without wishing to be limited to or relying on this theory - within the scope of the inventive concept an increase in the (further) tear resistance or tear-blocking or (further) tearing-preventing threads, at which a local reinforcement of the fabric can be present and at which, under (further) tearing stress, a further bundling of the additional threads having floats can occur, including the multiple or doubly inserted threads as a whole. According to an embodiment of the invention, it can also be provided that the multiple or doubly inserted threads equally have floats, so that this can also result in yarn mobility or displacement that improves the (further) tearing behavior.
[0078] The measures according to the invention, with the formation of floats on the one hand and the formation of multiple, in particular double, drawn-in warp threads or multiple, in particular double, inserted weft threads on the other hand, complement each other beyond the sum of the individual measures. This results in an increase in (further) tear resistance, namely in the form of a synergistic effect, which is equally surprising. Furthermore, the (further) tear resistance can be further positively influenced by a special application of the adhesive used to attach the protective layer to the fabric serving as the carrier layer, which will be discussed in more detail below.
[0079] Based on the technical measures according to the invention and their coordination, the (further) tear properties can thus be significantly improved overall, whereby an overall (further) tear-resistant product is provided in the form of the protective filter material according to the invention. Other textile-physical properties or parameters are not adversely affected. For example, the textile carrier layer in the form of the special fabric continues to exhibit high air permeability and water vapor permeability as well as defined properties with regard to tensile stress (maximum tensile force) and dimensional stability. Low surface weights can also be achieved for the textile carrier layer in the form of the special fabric and for the protective filter material as a whole. In particular, a high level of flexibility and pliability is still guaranteed, which, in the case of protective clothing, benefits wearer comfort.
[0080] For this reason too, the protective filter material according to the invention is particularly suitable for the production of or use as protective clothing, in particular because its properties (high air and water vapor permeability as well as high pliability or flexibility and very good haptic properties) also ensure a high level of comfort when worn. For example, heat build-up can be avoided even when the user (wearer) of the protective clothing is subjected to high physical strain. Due to the high flexibility or pliability of the material, protective clothing produced on this basis is snug and therefore comfortable to wear. The guarantee of a high level of comfort when worn is also considerable because it can further reduce the physical or physiological stress on the user (wearer) of the protective clothing, which is particularly important under adverse conditions of use and when the user (wearer) is subjected to high levels of strain.user of the protective clothing is of further benefit.
[0081] The properties of the protective filter material according to the invention are also advantageous for the inventive use or design of (technical) filters or technical filter applications, since stable filters or filter systems can be realized on this basis, which, not least, also feature high throughputs and high efficiency with respect to the media to be purified. Furthermore, such filters exhibit a high degree of fit and are easy to handle in filter applications.
[0082] Overall, the protective filter material according to the invention, due to its properties, is also suitable for technical filter applications, for example, for use in (technical) filters or filter materials, such as those used for the removal of all types of pollutants, odors, and toxins, for example, from air or gas streams. Due to the high air permeability, a high filter efficiency is achieved for a given flow capacity of the medium to be purified, while maintaining equally high mechanical resistance of the underlying filters.
[0083] In addition, the protective filter material according to the invention, due to the very special combination and coordination of the underlying technical measures according to the invention, also combines opposing or diametrically opposed product properties in one and the same material: In addition to the high mechanical resistance or stability, it also has high air permeability and water vapor permeability as well as flexibility or pliability, as previously mentioned.
[0084] Due to the properties underlying the protective filter material according to the invention, the protective filter material according to the invention is also generally simple and feasible to manufacture on an industrial scale, while the filter material is also easily standardizable and has uniformly reproducible or specifically adjustable properties. Furthermore, the protective filter material is easy to (further) process, particularly into protective clothing, (technical) filters, or the like.
[0085] The high (further) tear resistance of the protective filter material according to the invention is also associated, in particular, with a high stability and durability of the protective filter material of protective articles produced on this basis (for example protective clothing or technical filters).
[0086] In particular, the (propagation) tear resistance can be used as a measure of the high overall stability of the protective filter material according to the invention and products made from it. In particular, with regard to the protective filter material according to the invention, the high (propagation) tear resistance also means that smaller and locally limited damage to the material, such as small (incisions) or cuts as well as pinpoint punctures or the like, do not lead to (propagation) tearing, even under continued mechanical stress, and thus do not lead to a complete loss of protective performance. This is also of central importance for ensuring a high level of protection against harmful or toxic substances. Furthermore, the composite or laminate structure on which the protective filter material according to the invention is based, in particular, is highly stable.The protective filter material according to the invention thus also exhibits high resistance to delamination or the destruction of the overall layer structure, for example, due to the separation of individual layers. This also allows for good further processing or cutting of the protective filter material according to the invention, for example, with regard to cut pieces for the production of protective clothing or the like. Due to its excellent mechanical properties, the protective filter material according to the invention also exhibits high wash resistance and high abrasion resistance.
[0087] Overall, the protective filter material according to the invention can withstand strong mechanical or force-related stress, in particular high force-related tearing or tear propagation stress, as occurs, for example, in the case of protective clothing in military operations or in operations for hazard prevention or disaster control.
[0088] In summary, the applicant has thus surprisingly discovered that the mechanical properties, namely the (further) tear resistance, of a special fabric used as a textile carrier layer, in particular for a protective layer (for example based on an adsorption, particle, or aerosol filter material), can be significantly improved (which correspondingly also applies to the protective filter material according to the invention as such). The fabric has a warp thread system based on a plurality of warp threads and a weft thread system based on a plurality of weft threads, wherein, on the one hand, the fabric has floats in the warp direction and / or in the weft direction, or some of the warp threads or weft threads are designed to float, and wherein, on the other hand, some of the warp threads are inserted multiple times, in particular twice, or some of the weft threads are inserted multiple times, in particular twice.In addition, a special adhesive application to the fabric to attach the protective layer, as described below, can ensure the development of a high (further) tear resistance.
[0089] In the protective filter material according to the invention, in particular with a protective function against chemical or biological or nuclear or radioactive pollutants or toxins, the tear and tear propagation resistance can be significantly increased or improved, for example, by up to 1.25 times, preferably 1.5 times, and more preferably 2 times or more, compared to prior art materials in an unexpected way based on such a design. In particular, high air and water vapor permeability is still ensured, along with high tensile and seam loads, as well as high pliability and flexibility, as previously mentioned.
[0090] Overall, the protective filter material according to the invention particularly meets the high performance requirements for protective filter materials in the field of ABC or CBRN protection.
[0091] The term “fabric”, as used in the context of the present invention, particularly for the textile-technical design of the carrier layer, is to be understood broadly and relates in particular to a textile fabric which has or consists of a thread arrangement or design based on a warp thread system formed by warp threads (synonymously also referred to as warps or warp yarns), on the one hand, and a weft thread system formed by weft threads (synonymously also referred to as wefts or weft yarns), on the other hand. The warp threads and weft threads, or the warp thread system and weft thread system, can cross one another, in particular regularly or in a pattern, and in particular at an angle of approximately 90° or almost 90°. The fabric can have special warp or weft types. According to the invention, the fabric has, in particular, floats and multiple-drawn warp threads ormultiple inserted weft threads.
[0092] In general, the fabric used according to the invention is particularly such that the warp threads run or are inserted at least in the longitudinal direction of the fabric, in particular at least substantially parallel to the fabric edge, and that the weft threads run or are inserted at least substantially in the transverse direction, in particular substantially parallel to the fabric edge. The warp and weft threads in the fabric preferably cross over at respective weaving or crossing points. In this respect, a frictional connection of the respective threads preferably exists in a fabric. In the context of the present invention, this is particularly such that corresponding weaving or crossing points are, so to speak, bridged by the provided floats. The formation of floats reduces the number of crossing points with a high frictional connection.
[0093] In the context of the present invention, it has been achieved in a completely surprising way to adjust the frictional engagement and the associated slip resistance or yarn mobility of the warp or weft threads underlying the fabric in such a way that in the event of (further) tearing stress, the previously described bundling of the threads or yarns or the further stabilization of the fabric is ensured or realized.
[0094] The term “float” (synonymously also referred to as float) is to be understood broadly within the scope of the present invention and relates in particular with regard to a respective warp thread or weft thread to the distance between two binding or crossing points and in this context thus in particular to a thread section of a respective warp or weft thread which extends over or spans a defined plurality, i.e. over at least two threads running at least substantially transversely thereto (i.e. weft threads in the case of warp thread floats and warp threads in the case of weft thread floats). A float is characterized in particular in that the floating thread section extends over or spans at least two threads of the respective other thread system (weft thread system in the case of warp thread floats and warp thread system in the case of weft thread floats).In addition, it is particularly the case that a float or the floating (thread) section is delimited or enclosed by respective binding or crossing points. According to the invention, the term "float" refers in particular to a configuration such that the floats in the warp direction each extend over or span at least two weft threads, or respectively, or wherein the floats in the weft direction each extend over or span at least two warp threads.
[0095] In the context of the present invention, with regard to the floats provided, it is particularly the case, without wishing to be limited to or invoke this theory, that with corresponding (further) tearing stress, due to the high mobility of the underlying thread sections or the floating threads as a whole, amalgamation or bundling of adjacent (thread) groups is made possible, which leads to a stabilization and interruption of the fabric and interruption or prevention of (further) tearing.
[0096] In particular, within a group of adjacent warp threads, the multiple, in particular double, inserted warp threads each have an identical thread path, particularly with regard to the sequence of floats or the sequence of thread lifts or lowers. Furthermore, within a group of adjacent weft threads, the multiple, in particular double, inserted weft threads each have an identical thread path, particularly with regard to the sequence of floats or the sequence of thread lifts or lowers.
[0097] The term "twill weave" is to be understood very broadly within the scope of the present invention and refers in particular to a (basic) weave type underlying the fabric with the presence of a corresponding thread float, as defined here. In particular, this can also be such that the underlying thread float is gradually offset with respect to adjacent or parallel threads. In particular, the fabric can have a twill weave as the basic weave.
[0098] Furthermore, the term “multiple, in particular double (double) inserted warp threads” or “multiple, in particular double (double), inserted weft threads” as used in the context of the present invention refers in particular to a specific arrangement or specific course of the relevant warp threads or weft threads in the fabric.
[0099] In connection with the formation of multiple, in particular double (double), drawn-in warp threads of multiple, in particular double (double), inserted weft threads, it can be provided according to the invention in particular that the fabric has a ripstop weave (ripstop construction).
[0100] In further connection with the formation of floats in relation to the simply drawn-in warp threads or simply inserted weft threads, the fabric can be designed according to the invention in particular as a ripstop fabric in twill weave.
[0101] According to the invention, the terms "yarn" on the one hand and "thread" on the other hand are to be understood equally broadly. In particular, the terms "yarn" and "thread" are used synonymously, whereby the aforementioned terms generally represent a collective term for all linear textile structures. In principle, the yarn or thread can be in the form of a monofilament or a multifilament. In particular, the yarn or thread can comprise one or more fibers or filaments. Alternatively, the yarn or thread can also be in the form of a fiber yarn. In addition, a sheath / core yarn (synonymously also referred to as core / sheath yarn or core / sheath yarn) or a core yarn can be used. In general, corresponding combinations can also be used. Reference can also be made to the following explanations.
[0102] As far as the term "(further) tear resistance" used in the context of the present invention is concerned, also synonymously referred to as "(further) tear resistance" or the like, this refers in particular to the property of a textile material, and in particular of the protective filter material according to the invention or of the fabric used as a textile carrier layer, to withstand an applied (further) tearing stress. In particular, this term refers to the resistance of a material to further tearing or tearing of an already damaged or (pre-)torn section of the material. In this context, the term "(further) tear force" refers in particular to the force acting on a textile material which is necessary for the (further) tearing of damage already present or introduced in the material, in particular in the form of a defined incision or tear.The (further) tear resistance of a textile material represents an important and established criterion for the evaluation of the mechanical resistance of corresponding textile materials.
[0103] In the context of the present invention, the (propagation) tear strength is determined or specified in particular on the basis of the so-called (propagation) tear force according to the leg method or on the basis of the leg (propagation) tear force, in particular in accordance with DIN ISO 13937-2, which is also specified in the harmonized standard for chemical protection suits DIN SPEC 19429. In this context, the (propagation) tear force can be determined in particular by cutting a rectangular specimen in the middle, whereby the specimen length is e.g. 100 mm or 200 mm with a central cut in the longitudinal direction of 50 mm or 100 mm, e.g. with a specimen width of 50 mm or 200 mm. The investigations or tests can be carried out in particular on a testing machine of type Z005 from ZwickRoell GmbH & Co. KG. The (propagation) tear force is specified in the unit Newton (N).
[0104] In the following, the present invention is described with reference to preferred embodiments or illustrative drawings or figure representations, wherein the relevant statements apply to all aspects of the invention and wherein the corresponding preferred embodiments or configurations of the present invention are in no way limiting.

[0107] According to the invention, with regard to the fabric 3c used as textile carrier layer 3, the fabric 3c has warp floats 3f and / or weft floats 3g. Furthermore, for the fabric 3c used as textile carrier layer 3, within the scope of the present invention, the fabric 3c is particularly such that some of the warp threads 3d are present and / or designed with multiple, in particular double, (thread) insertion 3h, or that some of the weft threads 3e are present and / or designed with multiple, in particular double, (thread) insertion 3i. In this regard, reference can also be made to the illustrations according to Fig. 4 and Fig. 5.
[0108] In connection with the special design of floats in the carrier layer 3 provided according to the invention, the fabric 3c as a whole exhibits high (further) tear resistance, particularly since, under appropriate force loading, the defined yarn mobility enables efficient bundling or juxtaposition of the respective threads. However, the invention also provides that the fabric 3c as a whole nevertheless exhibits high slip resistance, so that the fabric 3c also exhibits high (dimensional) stability.
[0109] In connection with the presence of the previously mentioned floats of the warp threads and / or the weft threads, the invention is particularly such that the fabric 3c has a twill weave or can be formed on the basis of a twill weave.
[0110] Particularly with regard to the preferred embodiment according to the invention, according to which the fabric 3c has a twill weave or can be formed based on a twill weave or according to which the fabric 3c has the floats described according to the invention, it is particularly provided that the fabric 3c does not have a plain weave and / or is free of a plain weave. In particular, the fabric 3c is not formed as a plain weave in this regard. As detailed herein, the fabric 3c used as the textile carrier layer 3 can, within the scope of the present invention, be present or formed in particular as a ripstop fabric in a twill weave.
[0111] The presence of warp threads with multiple, in particular double, (thread) insertions 3h or of weft threads with multiple, in particular double, (thread) insertions 3i is accompanied by a further stabilization of the fabric 3c with regard to high (further) tear resistance. In particular, further mechanical stabilization is achieved, also with regard to the prevention of the formation of tears or the like in the event of (further) tear stress.
[0112] As previously explained, the invention is particularly such that a portion of the threads forming the fabric is provided with multiple, in particular double, (thread) insertion 3h or (thread) insertion 3i. In this context, the invention particularly provides that a portion, in particular the other portion, of the warp threads 3d is inserted simply (individually) and / or that a portion, in particular the other portion, of the weft threads 3e is inserted simply (individually), as particularly in Fig. 4 or Fig. 5. The other part mentioned above thus refers in particular to the part of the warp threads 3d or weft threads 3e which differs from the multiple, in particular double (double) drawn or inserted threads, which are thus drawn or inserted once.
[0113] According to the invention, the textile carrier layer 3 is generally designed as a woven fabric 3c with a warp thread system formed from a plurality of warp threads 3d and with a weft thread system formed from a plurality of weft threads 3e. In this context, the floats in the warp direction and / or the part of the floating warp threads 3d can be part of the warp thread system and / or form the warp thread system, and / or, preferably and, wherein the floats in the weft direction and / or the part of the floating weft threads 3e can be part of the weft thread system and / or can form the weft thread system. In this regard, reference can also be made in particular to Fig. 4 and Fig. 5.
[0114] As equally particularly in Fig. 4, the warp threads 3d, in particular in the warp thread system, can be arranged to run at least substantially parallel to one another, and / or, preferably and, the weft threads 3e, in particular in the weft thread system, can be arranged to run at least substantially parallel to one another. Fig. 4 also illustrates that the warp threads 3d, in particular in the warp thread system, are arranged at least substantially perpendicular to the weft threads 3e, or that the weft threads 3e, in particular in the weft thread system, are arranged at least substantially perpendicular to the warp threads 3d.
[0115] According to the invention, with regard to providing a high (further) tear resistance, the floats 3f, 3g are designed in such a way that, under the action of a forceful (further) tear stress, threads 3d, 3e arranged at least substantially parallel and / or in a common direction, in particular in the warp direction or in the weft direction, and preferably adjacent to one another, are at least partially and / or at least sectionally pushed together and / or bundled.In addition, it is provided according to the invention in particular that the floats 3f, 3g are designed in such a way that after the action of a forceful (further) tearing stress, threads 3d, 3e arranged at least substantially parallel and / or in a common direction, in particular in the warp direction or in the weft direction, and preferably adjacent to one another, are at least partially and / or at least sectionally pushed together and / or bundled and / or are present in a pushed together and / or bundled arrangement.
[0116] In particular, in this context, under the influence of a forceful (further) tearing stress, particularly in the area of the (further) tearing point or in a tear area or tear triangle, a displacement or bundling of the respective threads can occur or be caused, so to speak, so to speak, a local reinforcement of the material occurs, which requires a higher (further) tearing force for (further) tearing. This can effectively prevent (further) tearing. In this context, the threads with multiple, in particular double, (thread) insertion 3h or (thread) insertion 3i also lead to a further mechanical reinforcement of the material or the underlying fabric 3c, so that the (further) tear resistance is further increased.
[0117] According to the invention, the fabric 3c is particularly configured such that the floats 3f are formed in the warp direction such that, under the action of a forceful (further) tearing stress, preferably adjacent warp threads 3d are at least partially and / or at least partially pushed together and / or bundled. In particular, the floats 3f can be configured in the warp direction such that, under the action of a forceful (further) tearing stress, preferably adjacent warp threads 3d are at least partially and / or at least partially pushed together and / or bundled and / or are present in a pushed-together and / or bundled arrangement.
[0118] In a corresponding manner, the invention provides, in particular, that the floats 3g are formed in the weft direction such that, under the action of a force-induced (further) tearing stress, preferably adjacent weft threads 3e are at least partially and / or at least partially pushed together and / or bundled. In particular, the floats 3g can be formed in the weft direction such that, under the action of a preferably load-induced (further) tearing stress, preferably adjacent weft threads 3e are at least partially and / or at least partially pushed together and / or bundled and / or are present in a pushed-together and / or bundled arrangement, as described below and in Fig. 4 and Fig. 5 shown.
[0119] Furthermore, the invention provides in particular that the floats 3f in the warp direction and / or the floating warp threads 3d, in particular in the warp thread system, are arranged to run at least substantially parallel to one another and / or to run at least substantially parallel to any non-floating warp threads 3d that may be present. Furthermore, the invention provides in particular that the floats 3f in the weft direction and / or the floating weft threads 3e, in particular in the weft thread system, are arranged to run at least substantially parallel to one another and / or to run at least substantially parallel to any non-floating weft threads 3e that may be present.This ensures a particularly good overall displacement of the respective threads 3d, 3e under (further) tearing stress, accompanied by an efficient pushing together or bundling of the parallel threads 3d, 3e. Regarding the arrangement of the respective floats, reference can also be made to . Fig. 4 or Fig. 5.
[0120] According to an embodiment of the invention, the floats 3f in the warp direction and / or the floating warp threads 3d, in particular in the warp thread system, are arranged at least substantially perpendicular to the floats in the weft direction and / or at least substantially perpendicular to the floating weft threads 3e or are arranged at least substantially perpendicular to the non-floating weft threads 3e that may be present.Furthermore, the floats 3g in the weft direction and / or the floating weft threads 3e, in particular in the weft thread system, can be arranged at least substantially perpendicular to the floats in the warp direction and / or at least substantially perpendicular to the floating warp threads 3d and / or at least substantially perpendicular to any non-floating warp threads 3d that may be present. In this way, optimal stabilization or an increase in the (further) tear resistance can be achieved both in the warp direction and in the weft direction. This also means that the (further) tear resistance can be increased in all directions, relative to the main plane of extension of the carrier layer 3 or the fabric 3c.This ensures high tear resistance, independent of the direction of the applied tear stress, particularly since the threads with floats can be combined or bundled in both the warp and weft directions. This can also be done using . Fig. 4.
[0121] As equally in Fig. 4 and also in Fig. 5, the invention is particularly such that the floats 3f are formed along a respective warp thread path by (exactly) one warp thread 3d, preferably by a single (individually) inserted warp thread 3d. The warp threads comprising the floats can in particular be single (individually) inserted warp threads 3d. In addition, the floats 3g can be formed along a respective weft thread path by (exactly) one weft thread 3e, preferably by a single (individually) inserted weft thread 3e. In this regard, the weft threads comprising the floats can be formed by single (individually) inserted weft threads 3e.
[0122] With regard to the following explanations regarding floats 3f and 3g, the information on the extension and the information on the successive thread lifts can also be used as a measure of the length of a particular float. In this context, the respective warp threads 3d and weft threads 3e exhibit optimal properties with regard to the intended displacement, juxtaposition, and bundling under (further) tearing stress.
[0123] As far as the floats 3f in the warp direction are concerned, the following designs have proven to be particularly advantageous.
[0124] In particular, according to the invention, the floats 3f in the warp direction, in particular in the warp thread system, each extend over or span at least two weft threads 3e, preferably over (exactly) two weft threads 3e. In other words, in this regard, the floats 3f bridge at least two weft threads 3e, preferably (exactly) two weft threads 3e.
[0125] Furthermore, within the scope of the present invention, it can be such that the floats 3f in the warp direction, in particular in the warp thread system, each extend over a maximum of five weft threads 3e, in particular over a maximum of four weft threads 3e, preferably over a maximum of three weft threads 3e, preferably over a maximum of two weft threads 3e, and / or span these in each case.
[0126] In addition, it can be provided according to the invention that the floats 3f in the warp direction, in particular in the warp thread system, each extend over two to five weft threads 3e, in particular two to four weft threads 3e, and / or each span these.
[0127] In particular, according to a preferred embodiment of the invention, it can be provided that the floats 3f in the warp direction, in particular in the warp thread system, each extend over (exactly) two weft threads 3e and / or span them.
[0128] Due to the aforementioned designs or lengths of the floats 3f in the warp direction, on the one hand, a high thread or yarn mobility is achieved, which benefits the displacement and bundling of the warp threads 3d having the floats 3f under (further) tearing stress, while on the other hand, a defined slip resistance is still provided, so that the integrity or stability of the fabric 3c as such is still guaranteed.
[0129] With regard to the floats 3f of the warp threads 3d, it can also be provided according to the invention in particular that the floats 3f in the warp direction, in particular in the warp thread system, each have at least two (successive) thread lifts (warp lifts), preferably (exactly) two (successive) thread lifts (warp lifts).
[0130] In particular, the floats 3f in the warp direction, in particular in the warp thread system, can each have a maximum of five (consecutive) thread lifts (warp lifts), in particular a maximum of four (consecutive) thread lifts (warp lifts), preferably a maximum of three (consecutive) thread lifts (warp lifts), preferably a maximum of two (consecutive) thread lifts (warp lifts).
[0131] According to the invention, it can be provided in this context in particular that the floats 3f in the warp direction, in particular in the warp thread system, each have two to five (consecutive) thread lifts (warp lifts), in particular two to four (consecutive) thread lifts (warp lifts).
[0132] In addition, according to a particularly preferred embodiment, it can be provided that the floats 3f in the warp direction, in particular in the warp thread system, each have (exactly) two (successive) thread lifts (warp lifts).
[0133] According to the present invention, the floats 3f in the warp direction can be closed and / or enclosed at their respective ends, in particular at both ends, by at least one thread drop (warp drop), in particular (exactly) one thread drop (warp drop). This can also Fig. 4 or Fig. 5 can be taken.
[0134] In this context, the invention can provide for a series of respective floats 3f along a warp thread 3d, which are separated from each other by at least one thread drop (warp drop), preferably only by (exactly) one thread drop (warp drop). This also leads to particularly good displacement of the warp threads 3d and bundling in the event of (further) tearing stress.
[0135] According to the invention, it can be provided, in particular, that at least some of the warp threads 3d or the warp threads 3d, preferably along the respective warp thread course and / or with respect to the respective warp thread extension, are each designed to be at least substantially continuous and / or at least substantially completely floating. In particular, it can be provided that the floats 3f are present and / or arranged at least substantially along the entire warp thread course and / or at least substantially along the entire warp thread extension of the respective warp threads 3d. This also promotes the displaceability or mobility of the respective warp threads 3d under (further) tearing stress.
[0136] According to the invention, it can also be provided that at least some of the warp threads 3d or the warp threads 3d, preferably along the respective warp thread course and / or in relation to the respective warp thread extension, each have at least one float 3f, in particular at least two floats 3f, preferably a plurality of floats 3f, in relation to the weave repeat of the fabric 3c and / or in relation to an individual warp thread 3d having the floats 3f.
[0137] In this regard, it can also be provided according to the invention that at least some of the warp threads 3d or the warp threads 3d, preferably along the respective warp thread course and / or based on the respective warp thread extension, each have a number of floats 3f in the range from 2 to 50, in particular in the range from 2 to 40, preferably in the range from 3 to 30, preferably in the range from 4 to 20, based on the weave repeat of the fabric 3c and / or based on an individual warp thread 3d having the floats 3f.
[0138] The above numerical values relating to the number of floats therefore refer to a single warp thread 3d as such.
[0139] The following section will now discuss the formation of the floats 3g in relation to the weft threads 3e.
[0140] According to the invention, it can be provided in particular that the floats 3g in the weft direction, in particular in the weft thread system, each extend over at least two warp threads 3d, preferably over (exactly) two warp threads, and / or each span them.

[0142] Furthermore, the floats 3g in the weft direction, in particular in the weft thread system, can each extend over two to five warp threads 3d, in particular over two to four warp threads 3d, and / or span these. In particular, the invention can provide for the floats 3g in the weft direction, in particular in the weft thread system, to each extend over (exactly) two warp threads 3d and / or span these.

[0158] In particular, it can be provided according to the invention that at least 2, in particular at least 4, preferably at least 6, preferably at least 8, particularly preferably at least 10, warp threads 3d arranged next to one another and / or following one another, in particular simply (individually) drawn-in warp threads 3d, are designed to be floating and / or have floats 3f, in particular as defined above.
[0159] Likewise, it can be provided according to the invention that at least 2, in particular at least 4, preferably at least 6, preferably at least 8, particularly preferably at least 10, juxtaposed and / or successive weft threads 3e, in particular simply (individually) inserted weft threads 3e, are designed to be floating and / or have floats 3g, in particular as defined above.
[0160] In addition, according to an embodiment of the invention, it can be provided that each warp thread 3d, in particular in the warp thread system, is designed to be floating and / or has floats 3f and / or wherein the warp threads 3d in their entirety and / or all warp threads 3d are designed to be floating and / or have floats 3f and / or wherein 100% of the warp threads 3d, in particular in the warp thread system and based on the total number of warp threads 3d, are designed to be floating and / or have floats 3f, in particular as defined above; and / or, preferably and, that each weft thread 3e, in particular in the weft thread system, is designed to be floating and / or has floats 3g and / or wherein the weft threads 3e in their entirety and / or all weft threads 3e are designed to be floating and / or have floats 3g and / or wherein 100% of the weft threads 3e, in particular in the weft thread system and based on the total number of warp threads 3d, are designed to be floating and / or have floats 3g, in particular as defined above.
[0161] In addition, the fabric 3c used according to the invention as a textile carrier layer 3 can be designed as follows: Thus, the fabric 3c can have a burr formation (burr) and / or burr-shaped (thread) arrangement at least in sections and / or regions, in particular in the sections and / or regions formed by simply (individually) drawn-in warp threads 3d and / or by simply (individually) inserted weft threads 3e. For this purpose, for example, Fig. 5. This also results in a defined pattern with respect to the surface of the fabric 3c. In particular, the burr formation results from the special arrangement of the warp and weft threads 3d, 3e and the corresponding arrangement and formation of the floats 3f, 3g. The provision of a special burr formation also has a positive influence on the (further) tear resistance, also with regard to a controlled displacement of the respective threads to form a thread bundle under forceful (further) tear stress.
[0162] In this context, it can also be provided according to the invention that the respective float courses and / or sequences of adjacent warp threads 3d, in particular of adjacent simply (individually) drawn-in warp threads 3d, are offset and / or shifted relative to one another, preferably along the respective warp thread courses and / or with respect to the warp direction, in particular by at least one weft (thread) row and / or weft (thread) position, in particular so that a burr formation (or present burr) and / or a burr-shaped (thread) arrangement in the fabric 3c is present at least in sections and / or regions.
[0163] Furthermore, the respective float courses and / or sequences of adjacent weft threads 3e, in particular of adjacent simply (individually) inserted weft threads 3e, can be offset and / or shifted relative to one another, preferably along the respective weft thread courses and / or relative to the weft direction, in particular by at least one warp (thread) row and / or warp (thread) position, in particular so that a burr formation (or present burr) and / or burr-shaped (thread) arrangement in the fabric 3c is present at least in sections and / or regions.
[0164] Through the special burr formation based on the thread or float formation or arrangement, the (further) tear resistance can be further specifically adjusted or increased. In particular, the shiftability, juxtaposition, or bundling of the respective threads under (further) tear stress can be further optimized or improved.
[0165] In this context, it can also be provided according to the invention that the ridge formation (or the ridge) and / or ridge-shaped (thread) arrangement has at least one ridge direction change, in particular a plurality of ridge direction changes, in particular so that the ridge formation and / or ridge-shaped (thread) arrangement is present and / or designed as a herringbone, in particular wherein the ridge direction change occurs and / or is present at and / or adjacent to the multiple, in particular double, drawn-in warp threads 3d.
[0166] In the following, reference is made in particular to special embodiments of the multiple, in particular double (double) drawn-in warp threads 3d (warp threads 3d with multiple, in particular double, (thread) drawing-in 3h) or the multiple, in particular double (double) drawn-in weft threads 3e (weft threads 3e with multiple, in particular double, (thread) insertion 3i).
[0167] According to the invention, it can be provided in particular, as in Fig. 4 and Fig. 5 shows that (also) the multiple, in particular double, drawn-in warp threads 3d (warp threads 3d with multiple, in particular double, (thread) drawing-in 3h) and / or, preferably and, (also) the multiple, in particular double, inserted weft threads 3e (weft threads 3e with multiple, in particular double, (thread) insertion 3i) each have floats 3f, 3g and / or are each designed to float. Thus, the respective warp and weft threads 3d, 3e can also be specifically adjusted with regard to their behavior (displaceability) under (further) tearing stress.
[0168] In particular, against this background, it can be provided according to the invention that (also) the warp threads 3d which are drawn in multiple times, in particular twice (double), each have floats 3f and / or are each designed to be floating.
[0169] In this context, the warp threads 3d drawn in multiple times, in particular twice (double), within a group of adjacent warp threads 3d can each have an identical (overall) float course and / or an identical float sequence and / or formation, in particular the same sequence of thread lifts (warp lifts) and / or thread lowerings (warp lowerings), preferably along the respective warp thread courses and / or related to the respective warp thread extensions.
[0170] According to the invention, it can equally be provided that the multiple, in particular double (double), inserted weft threads 3e each have floats 3g and / or are each designed to be floating, in particular as defined above.
[0171] In this context, within a group of adjacent weft threads 3e, the multiple, in particular double (double), inserted weft threads 3e can each have an identical (overall) float course and / or an identical float sequence and / or formation, in particular the same sequence of thread lifts and / or thread lowering, preferably along the respective weft thread courses and / or related to the respective weft thread extensions.
[0172] According to an embodiment of the invention, however, it can also be provided that at least some of the multiple, in particular twice (double), inserted warp threads 3d have no floats and / or are each non-floating; or that at least some of the multiple, in particular twice (double), inserted weft threads 3e have no floats and / or are each non-floating. This can, for example, result in a more secure integration of the multiple inserted warp threads 3d or multiple inserted weft threads 3e in the fabric 3c, accompanied by a higher displacement force, for example under forceful (further) tearing stress. On this basis, the multiple inserted warp or weft threads 3d, 3e can - without wishing to rely on or be limited to this theory - form an additional tear blocking or (further) tear blocking, in particular also on the basis of the multiple orDouble thread insertion with the associated mechanical reinforcement. In particular, due to the higher displacement resistance of the multiple-inserted warp or weft threads 3d, 3e, floating warp or weft threads 3d, 3e can shift under (further) tear stress in the direction of the reinforcement formed by the multiple-inserted warp or weft threads 3d, 3e, forming a (further) tear-resistant thread bundle together with the multiple-inserted or inserted threads in this area.
[0173] Fig. 4 and Fig. 5 further illustrate an embodiment according to the invention, according to which it can be provided that, within a group of adjacent warp threads 3d, multiple, in particular twice (double), drawn-in warp threads 3d are arranged identically and / or coextensively along their warp thread courses and / or warp thread extensions and / or with respect to the warp direction. In particular, it can be provided according to the invention that, within a group of adjacent warp threads 3d, multiple, in particular twice (double), drawn-in warp threads 3d are arranged coextensively. In particular, within a group of adjacent warp threads 3d, multiple, in particular twice (double), drawn-in warp threads 3d can be at least substantially completely in contact with one another and / or at least substantially completely abut one another along their warp thread courses and / or warp thread extensions.The identical arrangement of the warp threads 3d forming a group of adjacent threads in the direction of the thread path provides even greater mechanical strength. Due to their identical arrangement, the warp threads 3d forming the group function, so to speak, as a single thread in mechanical terms. This simultaneously provides defined displacement properties under forceful (further) tearing stress. The identical or identical arrangement or the identical binding formation of the underlying warp threads 3d refers in particular to the entire warp thread path or the entire length of the respective warp threads in the warp thread system of the fabric 3d.
[0174] As particularly in Fig. 4 and Fig. 5, it can further be provided according to the invention that within two or more groups of non-adjacent warp threads 3d, multiple, in particular double (double), drawn-in warp threads 3d are spaced and / or separated in the fabric 3c, in particular in the warp thread system.
[0175] In this context, it can be provided in particular that the spacing and / or separation is carried out and / or provided by at least one single (individually) drawn-in warp thread 3d, in particular by a plurality of single (individually) drawn-in warp threads 3d, in particular wherein the respective single (individually) drawn-in warp threads 3d are arranged in the fabric 3c, in particular in the warp thread system, in particular next to one another between the multiple, in particular double (double), drawn-in warp threads 3d and the multiple, in particular double (double), drawn-in warp threads 3d adjacent thereto.
[0176] According to the invention, it can be provided that the spacing and / or separation is carried out or provided by 1 to 50, in particular 2 to 30, preferably 3 to 25, preferably 5 to 20, particularly preferably 7 to 15, simply (individually) drawn-in warp threads 3d.
[0177] By means of the aforementioned measures, high (further) tear resistances are provided according to the invention, even taking into account a low basis weight and given flexibility or pliability of the textile material or fabric 3c, wherein a defined thread mobility is also provided, in particular under (further) tear stress.
[0178] In a manner corresponding to the previously mentioned warp threads 3d, the weft threads 3e or the weft thread system of the fabric 3c can also behave as follows according to the invention: In particular, within a group of adjacent weft threads 3e, multiple, in particular double (double), inserted weft threads 3e can be arranged identically and / or coextensively along their weft thread courses and / or weft thread extensions and / or with respect to the weft direction. Furthermore, within a group of adjacent weft threads 3e, multiple, in particular double (double), inserted weft threads 3e can be arranged coextensively. Furthermore, within a group of adjacent weft threads 3e, multiple, in particular double (double), inserted weft threads 3e can be at least substantially completely in contact with one another along their warp thread courses and / or weft thread extensions and / or can be at least substantially completely in contact with one another.
[0179] Likewise, within the scope of the present invention, it may also be such that, within two or more groups of non-adjacent weft threads 3e, multiple, in particular double (double), inserted weft threads 3e are spaced and / or separated from adjacent multiple, in particular double (double), inserted weft threads 3e in the fabric 3c, in particular in the weft thread system.In particular, it can be provided in this context that the spacing and / or separation is effected and / or provided by at least one individually inserted weft thread 3e, in particular by a plurality of singly (individually) inserted weft threads 3e, in particular wherein the respective individually inserted weft threads 3e are arranged in the fabric 3c, in particular in the weft thread system, in particular next to one another between the multiple, in particular double (double), inserted weft threads 3e and the adjacent multiple, in particular double (double), inserted weft threads 3e. In this regard, the spacing and / or separation can be effected and / or provided by 1 to 50, in particular 2 to 30, preferably 3 to 25, more preferably 5 to 20, particularly preferably 7 to 15, singly (individually) inserted weft threads 3e.
[0180] In addition, the following designs have also proven to be advantageous with regard to the formation and coordination of the threads forming the fabric 3c: According to the invention, it can be provided in particular that the multiple, in particular double (double), drawn-in warp threads 3d and the remaining warp threads 3d, in particular the single (single) drawn-in warp threads 3d, have at least substantially identical and / or at least substantially equal titres (finenesses or thicknesses) and / or thread diameters compared to one another; and / or, preferably and, that the multiple, in particular double (double), inserted weft threads 3e and the remaining weft threads 3e, in particular the single (single) inserted weft threads 3e, have an at least substantially identical and / or at least substantially equal linear density (fineness or thickness) and / or thread diameter compared to one another.

[0184] The inventive use of threads with the same linear density or thread diameter also results in a uniform (cross-sectional) thickness of the fabric 3c, which results in improved material properties, particularly with regard to providing a uniform surface structure (improved feel and appearance) as well as defined flexibility or pliability. Furthermore, the uniformly structured surface also allows for better fixation or bonding with other layers, particularly with regard to the protective layer 5 of the fabric 3c.

[0212] The carrier layer 3 or the fabric 3c is also characterized by a low basis weight and, at the same time, high stability: In particular, the carrier layer 3, in particular the fabric 3c, can have a basis weight in the range of 40 g / m 2 up to 250 g / m 2 , especially in the range of 50 g / m 2 up to 200 g / m 2 , preferably in the range of 60 g / m 2 up to 150 g / m 2 , preferably in the range of 70 g / m 2up to 120 g / m 2 , have. The basis weight can be determined in particular according to DIN EN 12127:1997, preferably after 24 hours of conditioning or at a temperature of 20°C ± 2°C and a relative humidity of 65% ± 4%.
[0213] In addition, the thickness, in particular the cross-sectional thickness, of the carrier layer 3 or the fabric 3c is of corresponding importance with regard to the functional properties, for example with regard to bendability, flexibility, stability and air permeability. In general, the invention can provide for the carrier layer 3, in particular the fabric 3c, to have a thickness, in particular the cross-sectional thickness, in the range from 0.01 mm to 10 mm, in particular in the range from 0.05 mm to 5 mm, preferably in the range from 0.075 mm to 3 mm, more preferably in the range from 0.1 mm to 2 mm, particularly preferably in the range from 0.15 mm to 1.5 mm. The thickness or cross-sectional thickness can be determined in particular according to DIN EN ISO 5084:1996.
[0214] Furthermore, the carrier layer 3, in particular the fabric 3c, can have an air permeability of at least 5 l·m -2 s -1 , in particular at least 10 l·m -2 s -1, preferably at least 50 l·m -2 s -1 , preferably at least 100 l·m -2 s -1 , particularly preferably at least 200 l·m -2 s -1 , in particular determined according to DIN EN ISO 9237:1995 and / or in particular determined at a differential pressure (flow resistance) of 100 Pascal.
[0215] In particular, the carrier layer 3, in particular the fabric 3c, can have an air permeability of in the range of 5 l·m -2 s -1 up to 2,500 l·m -2 s -1 m, especially in the range of 100 l·m -2 s -1 up to 2,250 l·m -2 s -1 m, preferably in the range of 200 l·m -2 s -1 up to 2,000 l·m -2 s -1 m, preferably in the range of 400 l·m -2 s -1 up to 1,800 l·m -2 s -1m, in particular determined according to DIN EN ISO 9237:1995 and / or in particular determined at a differential pressure (flow resistance) of 100 Pascal.
[0216] In particular with regard to providing a high level of wearing comfort when using the protective filter material 1 according to the invention for or as protective suits, as well as with regard to the properties for use in technical filter applications, it is particularly provided according to the invention that the protective filter material 1 as such and thus also the carrier layer 3 and the fabric 3c are each designed to be gas-permeable, in particular air-permeable, and / or water vapor-permeable, preferably gas-permeable, in particular air-permeable, and water vapor-permeable, preferably air-permeable and water vapor-permeable.
[0217] According to the present invention, it can also be provided that the carrier layer 3 or the fabric 3c has been subjected to a finishing and / or pretreatment. In this context, the applicant has surprisingly discovered that this can further improve the properties of the carrier layer 3 or the fabric 3c, including with regard to (further) tear resistance.
[0218] In particular, according to the invention, it can therefore be provided that the carrier layer 3, in particular the fabric 3c, is finished and / or has a finishing treatment, in particular wherein the carrier layer 3, in particular the fabric 3c, has been subjected to a finishing treatment. Within the scope of the finishing, the following treatment steps in particular can be carried out, either individually or in an appropriate combination (preferably in the following order): In particular, it can be provided that the carrier layer 3, in particular the fabric 3c, is dyed, in particular using at least one reactive dye and / or at least one disperse dye, in particular at least one reactive dye and at least one disperse dye. The aforementioned dyes are associated with particularly good fixation on the carrier layer 3 or the fabric 3c and also do not lead to roughening of the material, so that the sliding properties of the warp threads 3d or weft threads 3e are maintained. - According to a particularly preferred embodiment, it can also be provided that the carrier layer 3, in particular the fabric 3c, is surface-treated, in particular by means of at least one polyolefin, preferably polyethylene, in particular using at least one polyolefin dispersion, preferably polyethylene dispersion. The targeted finishing of the carrier layer 3 or the fabric 3c of the aforementioned type is accompanied in particular by a further improvement in the (further) tear resistance, specifically also with regard to better sliding of the threads or yarns (warp threads 3d or weft threads 3e) under (further) tear stress. In addition, the abrasion resistance is also increased. The processing in the context of providing the protective filter material according to the invention or related protective clothing is also further improved, in particular with regard to the sewing properties.Furthermore, the surface quality of the carrier layer 3 or the fabric 3c is improved in terms of feel by the aforementioned treatment. In particular, this provides a softer or smoother surface. This also leads to improved gliding of the threads or yarns (warp threads 3d and weft threads 3e) during a (further) tearing process. Furthermore, particularly during finishing, it can be provided that the carrier layer 3, in particular the fabric 3c, is sanforized (shrunk). This increases the dimensional stability of the carrier layer 3, in particular the fabric 3c. In general, the carrier layer 3, in particular the fabric 3c, can also be shrunk using a tenter frame.
[0219] According to the invention, it can further be provided that the carrier layer 3, in particular the fabric 3c, is pretreated and / or has been subjected to a pretreatment, in particular before carrying out the finishing treatment, in particular as defined above. In this context, it may be provided that the carrier layer 3, in particular the fabric 3c, is singed. The singeing may be carried out thermally. This ensures, in particular, that, for example, protruding fine "fiber hairs" are removed. This measure also improves the sliding behavior of the yarns or threads (warp threads 3d or weft threads 3e) during a (further) tearing process. - Furthermore, according to the invention, the carrier layer 3, in particular the fabric 3c, can be desized. The desizing can be carried out enzymatically and / or using enzymes. This allows the removal of any previously present sizing film or coating, which in particular comprises starch. In this regard, starch-degrading enzymes, such as amylases, can be used. Furthermore, water-soluble sizes can also be used. - Furthermore, it can be provided, particularly within the scope of the pretreatment, that the carrier layer 3, in particular the fabric 3c, is bleached, in particular wherein the bleaching has been carried out using at least one bleaching agent, in particular sodium chlorite and / or hydrogen peroxide. This degrades, for example, residues, such as hydrophobic plant residues, on the fiber, thereby increasing hydrophilicity and improving dye uptake during dyeing (cf. above). In particular, a level or uniform dyeing can also be achieved on this basis during subsequent finishing. In particular, it can also be provided that the carrier layer 3, in particular the fabric 3c, is leached. In this regard, the leaching can be carried out using at least one alkali, in particular sodium hydroxide solution. The leaching can also serve to increase fiber strength. The carrier layer 3, in particular the fabric 3c, can in principle also be mercerized.
[0220] The aforementioned pretreatment also ensures, in particular, an optimization of the finishing process, as described above. The finishing and / or pretreatment measures according to the invention are directly reflected in the underlying carrier layer 3 or the fabric 3c, also with a view to improving the overall underlying (further) tear resistance.
[0221] Within the scope of the present invention, a very specific adhesive application or adhesive distribution, optimized with a view to ensuring high (propagation) tear resistance, can be used to bond the respective layers, in particular the fabric 3c and the protective layer 5, of the protective filter material 1 according to the invention. In this context, the specific adhesive application ensures that, even when the protective filter material 1 is formed in the form of a laminate or composite, a high degree of thread or yarn mobility is still present in the carrier layer 3 or the fabric 3c, and that the yarn mobility is not excessively influenced by the adhesive application. Consequently, even in the event of (propagation) tear stress, efficient aggregation or bundling of the respective threads is ensured despite the bonding, with a view to providing high (propagation) tear resistance.
[0222] As explained in detail below, within the scope of the present invention, the adhesive application for connecting the layers, in particular the fabric 3c and the protective layer 5, is designed in a targeted and purposeful manner such that the thread or yarn mobility in the main extension plane of the carrier layer 3 or the fabric 3c is still ensured, accompanied by the effective formation of the previously mentioned "bundle effect" or "cable effect" in the event of (further) tearing stress.
[0223] With regard to the preferably discontinuously applied adhesive 4 used to bond the carrier layer 3 or the fabric 3c and the protective layer 5, according to one embodiment of the invention, the adhesive 4 ("first adhesive") is present and / or designed in the form of adhesive (polymer) dots and / or in the form of a grid with a plurality of spaced-apart adhesive (polymer) dots. Overall, the adhesive 4 is preferably applied discontinuously and in particular in the form of dots or grids, so that the (adhesive) layer formed by the adhesive 4 or the adhesive polymer is permeable to air. In addition, an adhesive coating or a coating of the surfaces with the adhesive 4 can also be carried out by means of a doctor blade or by means of doctor blade application. In addition, the adhesive 4 can also be designed as an (adhesive) foam, in particular a broken (adhesive) foam.Adhesive webs or the like may also be used.
[0224] According to the invention, it has proven advantageous if the adhesive 4 (“first adhesive”) covers at most 75% of the surface of the carrier layer 3, in particular of the fabric 3c, and / or of the protective layer 5, preferably at most 60% of the surface of the carrier layer 3 and / or of the protective layer 5, particularly preferably at most 50% of the surface of the carrier layer 3 and / or of the protective layer 5, very particularly preferably at most 40% of the carrier layer 3, in particular of the fabric 3c, and / or of the protective layer 5.
[0225] In particular, the adhesive 4 (“first adhesive”) may be used in an amount in the range of 10 g / m 2 up to 100 g / m 2 , especially in the range of 15 g / m 2 up to 75 g / m 2 , preferably in the range of 20 g / m 2 up to 50 g / m 2, and / or in particular be present as an adhesive polymer. The above application quantities relate in particular to the surface or main extension plane of the carrier layer 3, in particular the fabric 3c.
[0226] Within the scope of the present invention, it is particularly provided that the adhesive 4 ("first adhesive") is designed and / or applied in such a way that the thread mobility, in particular the thread displaceability, preferably in the main extension plane of the carrier layer 3 or the fabric 3c, is at least substantially not impaired and / or at least substantially not restricted, in particular under forceful (further) tearing stress. Despite the existing bond, this is accompanied by a still high thread mobility, so that a high (further) tear resistance is still present. In particular, despite the bonding or the application of the adhesive, it is ensured that in the event of (further) tearing stress, the relevant threads, in particular warp threads 3d or weft threads 3e, can move and adhere to one another, in particular to form the "cable effect" or "bundle effect".
[0227] In this context, it can be provided in particular that the adhesive 4 ("first adhesive") is designed and / or applied in such a way that at least some of the warp threads 3d are at least substantially not bonded to adjacent warp threads 3d, at least in sections. In this regard, it is provided in particular that the proportion of non-bonded warp threads 3d is at least 10%, in particular at least 20%, preferably at least 30%, based on the total number of warp threads 3d. The term "in sections" refers in particular to at least 10%, in particular at least 20%, preferably at least 30%, of the total length of a respective warp thread 3d, in particular with regard to the sum or total length of the non-bonded sections.
[0228] In a corresponding manner, it can be provided according to the invention that the adhesive 4 ("first adhesive") is designed and / or applied in such a way that at least some of the weft threads 3e are at least substantially not bonded to adjacent weft threads 3e, at least in sections. In this case, it can be provided according to the invention that the proportion of non-bonded weft threads 3e amounts to at least 10%, in particular at least 20%, preferably at least 30%, based on the total number of weft threads 3e. The term "section by section" refers in particular to at least 10%, in particular at least 20%, preferably at least 30%, of the total length of a respective weft thread 3e, in particular with regard to the sum or total length of the non-bonded sections.
[0229] In particular, according to the invention, it can be provided that the adhesive 4 ("first adhesive") is designed and / or applied in such a way that at least a portion of the floats 3f of the warp threads 3d is at least substantially not bonded to adjacent warp threads 3d or over-stretched weft threads 3e. For this purpose, it can be provided that the portion of the non-bonded floats 3f amounts to at least 10%, in particular at least 20%, preferably at least 30%, based on the total number of floats 3f.
[0230] According to the invention, it can further be provided that the adhesive 4 ("first adhesive") is formed and / or applied such that at least a portion of the floats 3g of the weft threads 3e is at least substantially not bonded to adjacent weft threads 3e or over-spanned warp threads 3d. In particular, the portion of the non-bonded floats 3g can be at least 10%, in particular at least 20%, preferably at least 30%, based on the total number of floats 3g.
[0231] Furthermore, it has proven particularly advantageous in terms of ensuring high (further) tear resistance if some of the binding and / or crossing points of warp threads 3d and weft threads 3e are free of adhesive 4 and / or are not coated with adhesive 4 or are at most provided with adhesive with the proviso that the warp threads 3d and weft threads 3e are at least substantially not bonded to one another in the binding and / or crossing points.
[0232] In this regard, it can be provided according to the invention in particular that at least 20%, in particular at least 30%, preferably at least 40%, preferably at least 50%, of the binding and / or crossing points, based on the total number of binding and / or crossing points in the carrier layer 3, in particular fabric 3c, are free of adhesive 4 or are coated with adhesive 4, at most with the proviso that the warp threads 3d and weft threads 3e are at least substantially not glued to one another in the binding and / or crossing points.
[0233] According to the invention, this prevents the respective warp threads 3d or weft threads 3e from sticking together or fixing together at the binding or crossing points, which has proven particularly effective in ensuring high thread or yarn mobility.
[0234] In particular, for the protective filter material according to the invention, it may be the case that the adhesive 4 (“first adhesive”) is formed and / or applied in a dot matrix and / or discontinuous dot-shaped and / or non-continuous and / or in the form of adhesive (polymer) dots, preferably with at least substantially circular cross-section.
[0235] The formation of the adhesive (polymer) points with a circular cross-section refers in particular to a cross-section parallel to the main extension plane of the carrier layer 3 or the fabric 3c.
[0236] In particular, it can be provided that the adhesive 4 (“first adhesive”) is present and / or formed in the form of, in particular, non-contiguous adhesive (polymer) points, preferably non-contiguous and / or spaced apart and / or non-touching adhesive (polymer) points.
[0237] Furthermore, it can be provided according to the invention that the adhesive 4 (“first adhesive”) is present and / or formed in the form of a grid, in particular a regular grid, with a plurality of adhesive (polymer) points spaced apart from one another.
[0238] Furthermore, the adhesive 4 (“first adhesive”) can be applied electronically calculated and / or controlled and / or computer-based (particularly with regard to the use or formation of special stencils for adhesive application).
[0239] According to the invention, the adhesive 4 (“first adhesive”) can be applied by means of a stencil, in particular with a predetermined hole pattern and / or (hole) grid.
[0240] With regard to the application of adhesive 4 ("first adhesive") or the formation of the adhesive (polymer) layer, circular stencil technology can be used, for example. In particular, stencils with a regular grid structure can be used to form a regular pattern. In this regard, so-called CC stencils (Coating Circular stencils) can be used in particular. For this purpose, appropriate grids can be calculated or computer-aided, provided that the thread or yarn mobility is still ensured based on the adhesive application with a view to ensuring high (further) tear resistance.
[0241] In particular, the adhesive 4 ("first adhesive") can be applied using a stencil, in particular with an irregular pattern. In this regard, stencils with an irregular pattern or so-called CP stencils ("computer dot stencils") can be used. HD stencils, hexageometric stencils, or geometrically twisted hole stencils can also be used.
[0242] With regard to ensuring high thread or yarn mobility, it has also proven particularly advantageous if the adhesive 4 (“first adhesive”) is present and / or formed in the form of adhesive (polymer) dots.
[0243] In this context, it can be provided in particular that the diameter, in particular cross-sectional diameter, parallel to the main extension plane of the carrier layer 3 or the fabric 3c, of a respective adhesive (polymer) point is at most as large as, preferably smaller than, the diameter (thread or yarn diameter) of the warp thread 3d or weft thread 3e carrying and / or having the respective adhesive (polymer) point.
[0244] Furthermore, it can be provided in this regard that a respective adhesive (polymer) point, based on the vertical plan view of the main extension plane of the carrier layer 3 or the fabric 3c, at least substantially does not extend over the longitudinal extension of the warp thread 3d and / or weft thread 3e carrying and / or having the adhesive (polymer) point, preferably at least substantially does not extend over the diameter (thread or yarn diameter) of the warp thread 3d and / or weft thread 3e carrying and / or having the adhesive (polymer) point.
[0245] In particular, it can further be provided in this context that a respective adhesive (polymer) point, based on the vertical plan view of the main extension plane of the carrier layer 3 or the fabric 3c, is positioned at least substantially centrally on the respective warp thread 3d and / or weft thread 3e carrying and / or having the adhesive (polymer) point, preferably at least substantially centrally to the longitudinal axis, in particular the rotation axis, of the respective warp thread 3d and / or weft thread 3e carrying and / or having the adhesive (polymer) point.
[0246] Furthermore, it can be provided according to the invention that the penetration depth of the adhesive 4 ("first adhesive"), in particular in the form of adhesive (polymer) points, into the carrier layer 3, in particular the fabric 3c, is at most 50%, in particular at most 40%, preferably at most 30%, preferably at most 20%, based on the thickness, in particular cross-sectional thickness, of the carrier layer 3, in particular of the fabric 3c.
[0247] In particular, with regard to the adhesive application, the procedure can be such that, with respect to the carrier layer 3, in particular the fabric 3c, the adhesive (polymer) dots based on the adhesive 4 are positioned at least substantially centrally on the binding or crossing points of the warp threads 3d and weft threads 3e in the vertical plan view of the main extension plane of the carrier layer 3 or the fabric 3c. This ensures, in particular, that the adhesive (polymer) dots have no or at most only minimal contact with the underlying threads.
[0248] Furthermore, according to the invention, it may in particular be the case that the adhesive (polymer) dots based on the adhesive 4, based on the vertical plan view of the main extension plane of the carrier layer 3 or the fabric 3c, are positioned substantially centrally on a respective warp thread 3d or a respective weft thread 3e.
[0249] Furthermore, it can be provided according to the invention that the adhesive (polymer) points based on the adhesive 4 are positioned in the thread or yarn interspace in the warp thread system and / or weft thread system of the textile carrier layer 3, in particular of the fabric 3c.
[0250] According to the invention, it can also be provided that the adhesive (polymer) dots based on the adhesive 4 are positioned on adjacent warp threads 3d with floats and / or on adjacent weft threads 3e with floats. In particular, according to the invention, it can generally be the case that the adhesive (polymer) dots based on the adhesive 4 are positioned on adjacent floats of respective warp threads 3d or on adjacent floats of respective weft threads 3e. Such positioning - if at all - may lead to a (slight) connection of the respective threads or floats. According to the invention, however, this ensures that underlying threads can basically move freely. Likewise, at least sufficient displaceability of the threads connected in this way is also still ensured.
[0251] As previously stated, the special bonding or the special application of the first adhesive 4 results in particular in the thread or yarn mobility of the warp threads 3d or the weft threads 3e in the main extension plane of the carrier layer 3 or the fabric 3c being at least substantially unaffected, so that the present composite or the corresponding laminate also has excellent (further) tear resistance, since the bundling or the assembly of the respective threads under (further) tear stress is still ensured. In particular, the procedure according to the invention prevents the first adhesive from penetrating too deeply or excessively into the carrier layer 3 or the fabric 3c. In addition, the application or the presence of the first adhesive 4 at critical points (i.e. at points which, in the presence of an adhesive, would lead to excessive fixation orBlocking of the threads 3e, 3f is prevented or minimized. In particular, adhesion or fixation of intersecting warp threads 3d and weft threads 3e, particularly at corresponding binding or crossing points in the fabric structure, is also prevented or minimized. Furthermore, within the scope of the present invention, adhesion of adjacent warp threads 3d in the warp thread system and of adjacent weft threads 3e in the weft thread system of the fabric 3c is also prevented or minimized, so that overall yarn mobility is also maintained.
[0252] In this context, the invention provides, in particular, that, as previously stated, the adhesive (polymer) dots present during the discontinuous adhesive application have a defined formation or a specific positioning on the fabric 3c. Furthermore, there is a defined total area-related quantity of applied first adhesive 4, whereby the measures in question, both individually and in their interaction (and this in a synergistic manner), ensure high (further) tear resistance.
[0253] On the basis of the measures stated according to the invention, the bonding of the warp threads 3d or weft threads 3e at so-called “critical points” (i.e. points which are detrimental to the yarn mobility and thus to the (further) tear resistance) can be prevented or minimized. The term “critical points” is to be understood in particular in such a way that bonding or the application of adhesive 4 (“first adhesive”) at such points leads to a reduction in the yarn mobility and also possibly to an increase in the so-called thread pull-out force, so to speak as a measure of the reduction in thread or yarn mobility (yarn mobility). In this context, an excessive application of the adhesive to the critical points, for example in the area of connecting orIntersection points of the warp threads 3d and weft threads 3e, leading to a direct adhesive bond between the respective threads, can lead to reduced yarn mobility and thus ultimately to a reduction in (further) tear resistance, since this reduces or prevents the displacement or juxtaposition of the yarns to form the "cable effect" or "bundle effect" in the event of (further) tear stress. Due to the measures according to the invention, the formation of critical adhesive (polymer) points in this regard is thus counteracted.
[0254] According to the invention, it can also be provided in particular that the adhesive 4 ("first adhesive") is, in particular, a reactive hotmelt adhesive, in particular a moisture-crosslinking and / or radiation-crosslinking adhesive, preferably a moisture-crosslinking hotmelt adhesive, preferably a reactive, in particular moisture-crosslinking, polyurethane (PUR) hotmelt adhesive, or is based thereon, in particular wherein the adhesive 4 ("first adhesive") is, or is based on, a one-component adhesive. According to the invention, a reactive PUR-based hotmelt adhesive can be used as the adhesive 4 ("first adhesive"). In general, hotmelt adhesives can be used.
[0255] The method of applying the first adhesive 4 described above is particularly also associated with the advantage that the protective filter material 1 according to the invention can therefore also be provided with high flexibility or pliability while at the same time having high air and water vapor permeability and good haptic properties (e.g. soft feel).
[0256] According to the present invention, it can be provided in particular that the adhesive 4 (“first adhesive”) is a particularly reactive hot melt adhesive (hot melt), in particular a moisture-crosslinking and / or radiation-crosslinking adhesive, preferably a moisture-crosslinking hot melt adhesive, preferably a reactive, in particular moisture-crosslinking, polyurethane (PUR) hot melt adhesive, in particular wherein the adhesive 4 (“first adhesive”) is a one-component adhesive.
[0257] In particular, a reactive hot-melt adhesive based on polyurethane (PUR) can be used within the scope of the present invention. The aforementioned adhesives, in particular, do not require any additional auxiliaries, such as hardeners or the like. Furthermore, the aforementioned adhesives can be processed directly. With regard to the reactive hot-melt adhesives, as previously mentioned, the behavior is also particularly such that, during the adhesive application, an initial strength or bond buildup of the adhesive takes place, in particular based on physical processes (such as cooling), followed by final curing, in particular based on chemical processes. Overall, the aforementioned adhesives exhibit excellent application and processing properties while simultaneously providing high bond strengths in the resulting protective filter material 1.Also, due to the excellent processing and application properties of the aforementioned adhesives, a targeted and purposeful application to the carrier layer 3 or the fabric 3c can be achieved in such a way that the thread or yarn mobility is not permanently reduced, particularly in the event of (further) tearing stress, as previously explained. Overall, with regard to the first adhesive 4, the type of adhesive selected and / or the type of adhesive application can ensure, on the one hand, a firm and permanent bond between the carrier layer 3 or the fabric 3c and the protective layer 5 while simultaneously guaranteeing high (further) tear resistance.
[0258] In particular, the invention provides that the adhesive 4 ("first adhesive") in the protective filter material 1 is present or formed in the form of an adhesive polymer. Furthermore, the invention provides, in particular, that the adhesive 4 ("first adhesive") in the protective filter material 1 is present or formed as an air-permeable and water vapor-permeable and / or discontinuously formed adhesive layer, preferably based on or in the form of an adhesive polymer.
[0259] Furthermore, as regards the protective layer 5 of the protective filter material according to the invention, it can be characterized in particular by the following properties: In particular, according to the invention, it can behave in such a way that the protective layer 5 has a (total) basis weight in the range of 5 g / m 2 up to 600 g / m 2 , especially in the range of 20 g / m 2 up to 500 g / m 2, preferably in the range of 40 g / m 2 up to 400 g / m 2 , preferably in the range of 50 g / m 2 up to 300 g / m 2 , particularly preferably in the range of 60 g / m 2 up to 150 g / m 2 , in particular determined according to DIN EN 12127:1997, preferably after 24 hours of conditioning or at a temperature of 20°C ± 2°C and a relative humidity of 65% ± 4%
[0260] According to the invention, it is generally also such that (also) the protective layer 5 is designed to be gas-permeable, in particular air-permeable, and / or water vapor-permeable, preferably gas-permeable, in particular air-permeable, and water vapor-permeable, preferably air-permeable and water vapor-permeable.
[0261] The protective layer 5 serves, in particular, to provide additional protection against harmful or toxic substances that impinge on the protective filter material. In this regard, the protective layer 5 can be individually designed and tailored to the respective application or usage background, for example, with regard to providing adsorptive properties as well as aerosol or particle filtration properties. With regard to the protective layer 5, adsorptive properties and particle or aerosol filter properties can be combined through an appropriate structural design, as also outlined below.
[0262] As particularly in Fig. 1A and Fig. As illustrated in Figure 3A, according to an embodiment of the invention, it can be provided that the protective layer 5 comprises or consists of adsorber particles (adsorption particles) 5c, in particular a plurality of individual and / or discrete adsorber particles. In this context, it can be provided, in particular, that the adsorber particles 5c are arranged in layers and / or form a layer (cf. Fig. 1A or Fig. 3A). In particular, the adsorbent particles 5c can form an adsorption layer with respect to the protective filter material 1 or the protective layer 5 or can be arranged with respect to it.
[0263] According to a preferred embodiment of the invention, the adsorbent particles 5c are, or are formed by, activated carbon particles, preferably in the form of granular activated carbon particles ("granular carbon") or spherical activated carbon particles ("spherical carbon"), preferably in the form of spherical activated carbon particles. This achieves particularly good protection against harmful or toxic substances, such as warfare agents. Particulate adsorbents or adsorbent particles 5c in spherical form are particularly preferred, as this maintains the overall flexibility or pliability of the protective filter material 1 while simultaneously providing high protection.In addition, adsorber particles in spherical form, such as activated carbon particles in spherical form, are particularly suitable for fastening by means of a point-applied adhesive (in this case first adhesive 4), also with regard to ensuring high thread mobility under (further) tearing stress.

DIN EN ISO 139:2011), e.g., in an appropriately climate-controlled environment or test room. b) Fabric feel (haptics) and visual assessment For the determination and evaluation of the surface texture and fabric feel of the textile surface of the materials to be examined, the subjective perception of an assessing test person is used, whereby no aids are used in this context. c) Thread count The number of threads per unit length can be determined in particular according to DIN EN 1049-Part 2 (cf. Method B - Thread counter on a conditioned surface). d) Basis weight The basis weight can be determined in particular according to DIN EN 12127. In particular, this can be done by taking five measuring samples, distributed over the width of the fabric, from a conditioned textile surface using a cutting device, whereby the area of the cut is 100 cm 2 The samples are weighed on a basis weight scale under conditioned or specified conditions. e) Air permeability This test method involves measuring the air flow passing through a surface under specified conditions within a specific time period. The test is carried out in accordance with DIN EN ISO 9237. The conditioned textile surface is placed on a test area of 20 cm 2 at a differential pressure of 100 Pa, specifically on a TestTex Instruments test device. The procedure involves performing the air permeability test five times across the entire fabric width. f) Maximum tensile strength The maximum tensile strength can be measured using the so-called strip tensile test according to DIN EN ISO 13934-1. The textile fabric or the test specimen to be tested is stretched to breakage at a constant deformation rate. The test can be carried out in particular by ribbling several specimens (in particular six specimens) in each direction to a width of 50 mm ± 5 mm and cutting them to a minimum length that allows a clamping length of 200 mm. The pre-tension for textiles with a basis weight of < 200 g / m 2 is 2 N. The maximum tensile force can be determined in particular on a testing device (Zwick testing device) from ZwickRoell GmbH & Co. KG. g) Leg tear strength The tear strength test measures, in particular, the force required to further tear a textile material, in particular a fabric or a multi-layer protective filter material based on it. The test is carried out based on DIN EN ISO 13937-2. For single-layer textile materials, such as a fabric as such, a sample size of 100 mm x 50 mm can be selected based on the standard conditions according to DIN 53859-2:1979. The sample is cut 50 mm in the middle of the narrow edge to create two legs.For multi-layer textile materials, in particular multi-layer protective filter materials, samples with a size of 200 mm x 50 mm (with a 100 mm incision on a narrow edge) or 200 mm x 200 mm (with a 100 mm incision on one edge) are used, whereby the latter sample size is used in particular if, in the case of the smaller sample, threads are pulled out of the surface during the tearing process. The tests for the protective filter materials according to the invention are carried out in particular on the larger samples. At the end of the sample opposite the edge with the incision, a mark is drawn at a distance of 25 mm from that edge; this mark marks the end of the tear path. The incision results in two legs, which are fixed in the clamping jaws of the tensile testing machine.The legs formed by the incision are clamped into the upper and lower clamps of the testing machine without any pretensioning force. The fixed legs are moved apart at a defined deformation rate of 100 mm / min until the end of the tear propagation distance is reached. The test specimen is subjected to a continuously increasing tensile force. During the tensile test, a tensile force-displacement diagram is recorded. Each peak of the diagram corresponds to the maximum tensile force value upon tearing of one or more transverse threads. According to the standard specifications, the arithmetic mean is calculated from the recorded peak values. The tear force is expressed in Newtons (N). The leg tear force can be determined using several test specimens (in particular, five or six test specimens each), each cut in the warp and weft directions, with the mean value then being calculated for the respective directions.The examinations and tests can be carried out, in particular, on a Z005 testing machine from ZwickRoell GmbH & Co. KG. Reference can also be made to the above explanations. h) Dimensional change In this test method, which uses DIN EN ISO 5077, the washing shrinkage values can be determined in the longitudinal and transverse directions. The samples to be tested are first adjusted to a standard climate, and then a measuring distance of 500 mm is marked at three points in each direction using a water-insoluble pen. The test specimens are then washed according to DIN EN ISO 6330, program 4M (gentle wash at approximately 40 °C) with approximately 20 g of phosphate-free cover detergent on a Vebotech GmbH washer-dryer. After washing, the samples are dried in a tumble dryer until cupboard-dry and allowed to adjust to the climate for at least 24 hours. The dimensional change can be determined in both the longitudinal and transverse directions using the following formula: xt−x0x0∗100 where x0 is the initial dimension and x t represents the measurement taken after treatment. 2. Material investigations and properties
[0371] The following are studies on the textile-physical properties of various textile materials, namely single-layer textile materials in the form of various textile fabrics, and multi-layer protective filter materials using various fabric designs with respect to the carrier layers used. These include: a) Textile physical properties of (single-layer) textile materials in the form of different fabric types
[0372] This document describes single-layer textile materials in the form of various fabric types, which can also be used as carrier layers in protective filter materials. The textile materials mentioned are based on the use of sheath / core yarns with cotton as the sheath material and polyester as the core material, with the core or core consisting of several polyester (PES) filaments. The weight ratio of cotton to polyester is 59 to 41. (i) A first textile material G1 is in the form of a plain weave fabric (plain weave). The first textile material G1 has no floats or is free of floats (i.e. the first textile material G1 is free of floats extending in the warp direction over or spanning at least two weft threads and free of floats extending in the weft direction over or spanning at least two warp threads). The first textile material G1 also has no warp threads that are drawn in multiple times or twice, and no weft threads that are inserted multiple times or twice (i.e. the textile material G1 is free of warp threads that are drawn in multiple times or twice and free of weft threads that are inserted multiple times or twice). The first carrier material G1 has a warp thread count of approximately 30 warp threads / cm and a weft thread count of approximately 24 weft threads / cm.The basis weight of the first textile material G1 is 90.9 g / m. 2 . The first textile material G1, as a pure plain weave, has, with regard to tear resistance, a tear strength in the warp direction (warp tear strength) of 20.8 N and a tear strength in the weft direction (weft tear strength) of 21.3 N. (ii) A second textile material G2 is in the form of a ripstop fabric in plain weave (ripstop plain weave). The textile material G2 has no floats or is free of floats (i.e., the second textile material G2 is free of floats extending in the warp direction over or spanning at least two weft threads and free of floats extending in the weft direction over or spanning at least two warp threads). In addition to single-inserted warp threads and single-inserted weft threads, the second textile material G2 also has double-inserted warp threads and double-inserted weft threads. The second textile material G2 has a warp thread count of approximately 30 warp threads / cm and a weft thread count of approximately 26 weft threads / cm. The basis weight of the second textile material G2 is 91.6 g / m 2. The second textile material G2 in the form of the ripstop fabric in plain weave has, with regard to tear resistance, a tear strength in the warp direction (warp tear strength) of 39.6 N and a tear strength in the weft direction (weft tear strength) of 42.1 N. (iii) A third textile material G3 is in the form of a ripstop fabric in twill weave (ripstop twill fabric). The textile material G3 has floats, namely floats extending over or spanning two weft threads in the warp direction and floats extending over or spanning two warp threads in the weft direction. In addition to single (individual) drawn-in warp threads and single (individual) inserted weft threads, the third textile material G3 also has double drawn-in warp threads and double inserted weft threads. The third textile material G3 has a warp thread count of approximately 30 warp threads / cm and a weft thread count of approximately 27 weft threads / cm. The basis weight of the third textile material G3 is 87.6 g / m 2The third textile material G3 in the form of the ripstop fabric in twill weave has, with regard to tear resistance, a tear strength in the warp direction (warp tear strength) of 50.5 N and a tear strength in the weft direction (weft tear strength) of 64.6 N.
[0373] The above statements show that the third textile material G3 and the second textile material G2 each have improved properties with regard to tear resistance compared to the first textile material in the form of the simple plain weave, with the third textile material G3 having even better properties than the second textile material G2. Overall, the third textile material G3 in the form of the ripstop fabric in twill weave (i.e. with corresponding floats and with double-inserted warp threads and double-inserted weft threads (in addition to single-inserted or single-inserted warp threads or single-inserted or single-inserted weft threads)) has the greatest improvement in tear resistance, both in the warp direction and in the weft direction of the fabric.
[0374] The targeted and purposeful combination of the formation of floats, as previously mentioned, and double-inserted warp threads or double-inserted weft threads in one and the same material leads, in a synergistic manner, to a significant increase in tear resistance or the underlying tear force. In particular, without wishing to be limited or invoked by this theory, an effective bundling of the underlying threads can be observed for such a fabric under tear stress, which, in conjunction with the further reinforcement of the fabric by the double-inserted warp threads or the double-inserted weft threads, leads to the mechanical reinforcement of the fabric. In this way, tear propagation can be effectively halted or prevented in the tear zone or tear triangle, even under the influence of high force.
[0375] In particular, the third textile material, G3, is characterized by its special design as a ripstop fabric with a twill weave, which also results in high yarn mobility due to the floating threads, with effective bundling in the tear zone or tear triangle, resulting in higher yarn strength absorption. This is further enhanced by the double or twofold threads. Overall, the third textile material, G3, exhibits the best properties in terms of tear resistance as a measure of mechanical stability, particularly under tear stress, even compared to material G2. The special design of the third textile material, G3, thus provides an overall more tear-resistant product.The material in question also exhibits excellent other textile-physical properties, in particular with regard to providing high dimensional stability, high maximum tensile strength and high air permeability with an overall low basis weight of the material. b) Textile-physical properties of multilayer protective filter materials
[0376] This article describes the textile-physical properties of various multilayer protective filter materials which are manufactured on the basis of the textile materials listed in section a as respective carrier layers.
[0377] For the protective filter materials, it is also the case that an adsorption material in the form of spherical activated carbon is used for the respective protective layer, in particular with an average particle diameter of approximately 0.3 mm and with an area-related application quantity of approximately 80 g / m2 The adsorbent particles are attached to the carrier layer in the form of the respective fabric using a reactive polyurethane (PUR)-based hot-melt adhesive (one-component adhesive). The adhesive is applied in a surface-related amount of approximately 33 g / m 2 in a defined dot-like application using a CC stencil. On the side of the protective layer opposite the carrier layer, a thin nonwoven layer based on polyamide with a basis weight of 25 g / m is applied for the respective protective filter materials using a dot-like adhesive. 2 The resulting multilayer protective filter materials are further characterized with regard to their textile-physical properties in relation to tear resistance. (i) A first protective filter material S1 (comparison) is based on the previously described textile material G1 (plain weave fabric without floats and without multiple drawn warp threads or without multiple drawn weft threads) as a carrier material. The first protective filter material S1 based on G1 as a carrier layer exhibits tear strength values of 12.9 N and 14.1 N, respectively. (ii) Furthermore, a second protective filter material S2 (according to the invention) is characterized with regard to its tear resistance. The second protective filter material S2 is based on the second textile material G2 used as the carrier layer (ripstop fabric in plain weave, i.e., without floats and with double-inserted warp threads or double-inserted weft threads). With regard to tear resistance, the protective filter material S2 has corresponding values for the tear strength of 24.7 N and 34.1 N, respectively. (iii) A third protective filter material S3 (according to the invention) is based on the use of a third textile material G3 (namely in the form of a ripstop fabric in twill weave, i.e., with floats as described above, and with double-inserted warp threads or double-inserted weft threads) as a carrier layer. Regarding tear strength, corresponding tear strength values of 40.6 N and 54.4 N are determined. For another material sample, tear strength values of 38.7 N and 58.6 N are also determined.
[0378] The above statements show that the protective filter material S3 according to the invention with the special carrier layer in the form of a ripstop fabric in twill weave, as well as the protective filter material S2 according to the invention, each have higher tear propagation values than the protective filter material S1, with the protective filter material S3 being significantly improved compared to the protective filter material S2. Within the scope of the present invention, a significant increase in tear propagation resistance is thus made possible by using a very specially designed fabric as the carrier layer, and this with a multi-layer design and the formation of an adhesive bond. Furthermore, for the protective filter material S3, the special adhesive application results in only minor changes in tear propagation resistance, which is also the case to a certain extent for the material S2.In particular, the special combination of a twill weave ripstop fabric with the defined discontinuous or dot-grid adhesive application, as realized in S3, leads to very high values in terms of tear resistance even after bonding.
[0379] In particular, without wishing to rely on or limit oneself to this theory, it may also be the case that in the fabric formation according to S3 with the use of floats, fewer critical points are present or bonded, which is accompanied by high yarn mobility and tear resistance even after bonding or formation of the laminate. c) Further properties of the protective filter materials
[0380] Furthermore, the protective function against harmful or toxic substances, in particular chemical warfare agents, of the previously mentioned protective filter materials S1 to S3 is characterized, namely based on Method 2.2 of CRDEC-SP-84010 and with respect to bis[2-chloroethyl] sulfide (mustard gas, HD). The relevant properties are determined before and after exposure to a force-based tear propagation stress. Before tear propagation stress, all protective filter materials S1 to S3 exhibit standardized protective properties (barrier effect less than 4 µg / cm 2per 24 h). Furthermore, corresponding material sections or samples of the protective filter materials S1 to S3 are subjected to a tear propagation test, whereby the samples are previously provided with a defined incision. A force of approximately 10 N is applied for a defined period of time. Subsequently, the material sections or samples of the protective filter materials S1 to S3 subjected to this test are examined for their protective function against harmful or toxic substances, as previously described, for the area below the originally introduced incision. In this context, a value of 6.9 µg / cm 2 per 24 hours. The protective filter material S2 has a value of 2.8 µg / cm 2 per 24 hours. For the protective filter material S3, the value is 0.8 µg / cm 2per 24 hours. The values illustrate that, as previously stated, significant damage is already present for the protective filter material S1 in the area below the incision after the force load, accompanied by a higher penetration of the pollutant or toxic substance. Significantly lower values are found for the protective filter materials S2 and S3, with the protective filter material S3 exhibiting the best values in this regard.
[0381] Overall, within the scope of the present invention, also against the background of the above statements, high-performance protective filter materials are provided which have a high mechanical stability even during or after high force loads, wherein in this context an excellent protective function against harmful and toxic substances is also provided and also excellent application properties, for example with regard to processing into protective clothing or filters or filter systems, the provision of a high air permeability and good drapability of the material with an overall low basis weight and good haptic properties.
