Description

[0001] The present invention relates to the technical field of, in particular, textile protective clothing with a protective function against chemical and / or biological and / or radioactive pollutants or toxins (such as hazardous substances, combat agents or the like), as it can be used in particular in the military and civilian sector.

[0002] In particular, the present invention relates specifically to a textile ABC protective garment or a CBRN protective garment (where ABC = atomic, biological, and chemical, and CBRN = chemical, biological, radiological, and nuclear; the terms ABC and CBRN are used synonymously within the scope of the present invention). In this context, the present invention thus also relates to the technical field of corresponding textile ABC or CBRN protective clothing, such as that which can be used for military or civilian purposes, for example in the field of hazard prevention, firefighting, disaster relief, or the like.

[0003] Against this background, the present invention relates in particular to a textile protective garment, especially one with a protective function against chemical, biological, or radioactive pollutants or toxins (i.e., chemical pollutants and / or toxins, biological pollutants and / or toxins, and / or radioactive pollutants and / or toxins), such as chemical warfare agents, wherein the protective garment comprises or is formed from a specially designed textile material based on an outer material (top layer or outer fabric) and an adsorption filter (inner) material (inner layer or inner fabric), wherein the protective garment is formed from several sections of the multilayered textile material, wherein adjacent or overlapping sections are joined together by means of a special sewing or a special connecting seam, in particular at the edges.are connected to each other, particularly in a connection area at the edge.

[0004] In this context, the present invention also relates to the use of the protective material according to the invention for the manufacture of equipment or protective articles as well as for the manufacture of filters and filter materials.

[0005] Furthermore, the present invention also relates to the use of a sewing (stitching) and / or a joining seam for equipping a textile protective garment with an improved and / or increased displacement resistance (displacement resistance) of the textile layers of the protective garment.

[0006] Furthermore, the present invention also relates to the use of a connection area, particularly on the edge, of several, in particular at least two, sections (cut pieces) of a multi-layered textile material of a textile protective garment for equipping the textile protective garment with an improved and / or increased displacement resistance (displacement resistance) of the textile layers of the protective garment.

[0007] Likewise, the present invention also relates to a method for equipping a textile protective garment with an improved and / or increased displacement resistance (displacement resistance) of the textile layers of the protective garment.

[0008] The present invention further relates to a method for connecting, in particular without displacement, corresponding parts of a multi-layered textile material by means of a special sewing or by means of a special connecting seam in a protective garment or protective material or for the corresponding design.

[0009] Furthermore, the present invention also relates to the use of a special connecting seam for forming a connecting area that is in particular free from displacement in a protective clothing item or protective material, or for the corresponding formation.

[0010] Finally, the present invention also relates to the use of a textile protective garment according to one of the preceding claims for equipping and / or providing a user and / or wearer of the protective garment with a protective function against chemical and / or biological and / or radioactive harmful and / or toxic substances (warning agents) ("ABC protection function or CBRN protection function"), preferably for civilian or military purposes.

[0011] Toxic substances generally pose a high risk, causing adverse health effects for anyone who comes into contact with them. Therefore, exposure or contact with these substances, for example through skin or mucous membrane contact, inhalation, ingestion, or similar means, should be avoided or at least minimized. This is especially important given that the health risks and toxic potential of such substances can be significant, and even contact with or ingestion of small amounts can lead to lasting health problems and even death. It should also be noted that toxins and pollutants can exist in numerous chemical and physical forms, such as gases, liquids, or solids, and as finely particulated aerosols or other particles.from pollutant particles or the like that are present in the (ambient) air.

[0012] Against this background, there is a great need to provide appropriate protective clothing with ABC or CBRN protection to people at risk of coming into contact with toxic or hazardous substances, such as soldiers, firefighters, police officers, members of special or special units, or the like, in order to prevent the absorption of such toxic or hazardous substances during operations in contaminated or polluted environments by wearing the protective clothing.

[0013] Especially for groups of people such as soldiers, firefighters, police officers, members of special forces, and the like, who are at increased risk of coming into contact with toxic or hazardous substances, it is particularly important and necessary to ensure appropriate protection against these substances. In particular, toxic or hazardous substances can often be absorbed not only through the respiratory system but also through the skin, which poses a significant risk. Therefore, it is often necessary for these individuals to wear appropriate protective clothing (ABC or CBRN protective clothing) in addition to a respirator to prevent contact of the toxic or hazardous substances with the skin or body.In this context, such protective clothing, such as protective suits, jackets or the like, often also includes appropriate headgear or head covering, for example in the form of a hood or balaclava.

[0014] In this context, the general purpose of ABC / CBRN protective clothing is to provide the wearer / user with optimal or enhanced protection against hazardous or toxic substances, particularly insofar as the wearer / user is both as well protected as possible and can continue to perform their duties or activities as unhindered as possible. Therefore, in addition to providing appropriate protection against toxic or chemical agents, the comfort provided by the protective clothing plays a significant role, both in terms of a good fit and the provision of moisture-wicking or thermoregulating properties. A major challenge in providing such protective clothing is to create a comprehensive and / or versatile range of options.The aim is to provide comprehensive and reliable protection against a wide variety of different toxins and pollutants, including those present in various (physicochemical) forms. The often conflicting requirements of providing a high level of protection on the one hand and a high level of wearing comfort on the other should be met equally within a single material.

[0015] With regard to protective clothing, it is also necessary to ensure the longest possible and most versatile protection against toxins and pollutants, with the protective function being guaranteed even at high local concentrations of toxins or pollutants (for example, if a drop of a toxin or pollutant directly lands on the protective clothing). This protective function should also be guaranteed for extended periods and under adverse operating conditions, including at particularly critical sections or areas of the protective clothing, such as seams and joints connecting the individual textile sections or pieces that make up the protective clothing, and at edges and transitions, for example, where individual sections are joined.The layers of the components used, as well as transition or opening areas (penetration areas) of the protective clothing, such as head or neck openings, face openings, abdominal or pelvic openings, arm or hand openings, and leg or foot openings, or the like, are particularly problematic. The same applies to transition or connection areas of protective clothing worn together or simultaneously, such as between a protective jacket and protective trousers, or between a sleeve of a protective jacket and a glove or protective system (such as the transition or connection area or interface between a head covering or hood and a respirator, or the like). Such areas and sections are particularly problematic with regard to providing an efficient and lasting seal against the ingress of harmful or toxic substances.

[0016] To improve wearing comfort while maintaining a high level of protection against harmful substances, air-permeable protective clothing systems are known in the prior art. These systems can be equipped with an adsorption filter layer, particularly to ensure protection against harmful substances. Such protective systems offer improved wearing comfort and generally good protection against harmful substances due to the increased exchange of air and water or water vapor. In some cases, the adsorption material used in such protective clothing is positioned on the side of the material facing the wearer, allowing any harmful substances that have previously penetrated the material to be absorbed by the adsorption material.

[0017] The aforementioned breathable protective clothing is often manufactured using various, and especially layered, textile materials for specific functional or wear-related applications. The corresponding layers or sections are permanently joined together by seams or seam connections. These seam connections generally run through the entire surface of the material, often completely encompassing the thickness of the underlying protective material or the layers used. However, such seam connections represent weak points regarding the potential penetration of hazardous or toxic substances, particularly liquids, especially when high concentrations or large quantities are present. This is because seams running through the material cross-section can act as penetration points.These openings can create entry points for harmful or toxic substances from the outside, for example in droplet or aerosol form, especially since the yarns or threads used for seam construction can conduct harmful or toxic substances through the material along their path. This can lead to local penetrations of harmful or toxic substances, particularly under high (local) hazardous substance exposure, posing a corresponding risk to the wearer or user of the protective clothing. Furthermore, adsorption materials sometimes used at the underlying (seam) penetration points can quickly become overloaded, allowing the penetrated harmful or toxic substances to spread on the inside of the protective clothing, the side facing the wearer.

[0018] In this context, it may be possible in the prior art to seal such seams or seam connections to a certain extent using so-called seam sealing tapes, whereby air- and water- or water-vapor-impermeable materials, such as polymer or plastic tapes, which are generally designed as flat tapes, are used for this purpose and are applied, for example, along the seam line to cover the seam and the adjacent material. Adhesives are generally used for this purpose.

[0019] While this method can provide a certain degree of protection against external pollutants and toxins, such sealing concepts are insufficient. For example, the adhesive bond can detach, particularly under mechanical or thermal stress, which often occurs during application or use, exposing the previously sealed seam. Furthermore, pollutants and toxins can bead up or run off the seam sealing tape and be transferred in larger quantities to the adjacent (textile) material, potentially overloading it. There are also production-related disadvantages, as the air- and water-vapor-impermeable seam sealing tape must be applied subsequently, requiring separate production processes and steps. Additionally, the stability and...The function of the seal and the protective material equipped with it may be reduced due to material incompatibilities or the like.

[0020] In this context, aging processes are also problematic, such as those caused by UV or temperature influences, or by washing or decontamination processes, which can lead to a loss of function in the corresponding bonds. Furthermore, mechanical stress on the material, particularly with regard to tensile or bending stress, can lead to the detachment of the adhesive bond, accompanied by a negative impairment of the protective function against harmful or toxic substances.

[0021] The same applies to the formation of welds to join corresponding material sections or parts, as such connections likewise lack the desired stability. Furthermore, the formation of adhesive or welded joints is sometimes complex in terms of design and manufacturing, and the comfort of the resulting protective clothing may be compromised by a certain stiffening of the bonded or welded material sections.

[0022] Furthermore, wearing comfort can be reduced because the seam sealing tapes used are often thick and inflexible, properties which are further exacerbated by the additional use of an adhesive. The washability and regeneration resistance of such systems is also insufficient, as the resulting high material stress can cause the seam sealing tape to detach. In particular, it is difficult to perform visual inspections for condition and wear, especially with regard to detecting minor detachments or similar issues with the seam sealing tape. Moreover, airtight and watertight seam sealing tapes, with their associated adhesive bonding, are not suitable for sealing or...Covering seams used to join (surface) sections based on different materials, as material incompatibilities can occur here as well, especially with regard to the adhesive used.

[0023] Furthermore, prior art uses textile reinforcement layers for joining inserts or sections of an outer textile layer of protective clothing in the seam area. In this context, WO 2019 / 129656 A1 and EP 3 731 939 A1, which belongs to the same patent family, relate to protective clothing with an air-permeable textile layer forming the outer layer, based on a plurality of inserts or sections joined together by sewing, and with a textile layer forming the filtering material layer. In the area of ​​a joint, the protective clothing has a textile layer, designated as a reinforcement layer, which is both hydrophilic and oleophilic and is joined to two inserts or sections of the outer textile layer by the same seam. Due to the properties of the reinforcement layer, the material is intended to be infused with water or other substances.Harmful substances or toxins penetrating through the seam are absorbed in a targeted manner due to the absorbent properties or high affinity of the reinforcement layer and passed on to the filtering material layer.

[0024] The concept employed is that harmful or toxic substances impacting the protective clothing are selectively absorbed and transferred to the filtering material layer or adjacent material structures. However, this can lead to rapid depletion or local overload of the adjacent materials, and especially the filtering material layer, meaning that optimal protection is not always achieved. In particular, the material used as a reinforcement layer has no or at least insufficient adsorptive properties.

[0025] A particularly critical structure with regard to the unwanted penetration or ingress of harmful or toxic substances is the area or transition zone of openings in protective clothing for the intake or passage of body parts or extremities, such as arms and legs, of the wearer or user. The same applies to the transition zone or contact zone between different elements of protective clothing, for example, a protective jacket on the one hand and protective trousers on the other, or a protective jacket or sleeve on the other hand and a glove on the other.

[0026] In the transition areas of openings in protective clothing for the insertion or passage of body parts or extremities, the underlying protective material is often subjected to particularly high stress, for example, with regard to the connection of corresponding material sections in such areas. For instance, high tensile or strain forces can act on the material or the connection, such as if additional gloves or shoes are worn in the transition area, or if corresponding material sections are additionally secured to the extremities, for example, with straps or similar devices.In particular, a sufficiently stable connection between the corresponding material sections is not always present in such transition areas, resulting in sometimes suboptimal mechanical strength, for example, with regard to unsatisfactory resistance to tensile and elongation stress. Therefore, weak points or points of penetration for harmful or toxic substances can occur at such connection points, leading to a higher risk for the wearer or user of such protective clothing.

[0027] In general, the seams or joints of protective clothing, which connect the respective surface materials or sections, represent weak points with regard to the penetration of harmful or toxic substances. This is because the surface materials forming the protective clothing are pierced or penetrated by the thread or yarn forming the seam, weakening the structure. Harmful or toxic substances acting on the protective clothing from the outside can then be channeled or transported inwards along the thread or yarn through the material or its arrangement, which is undesirable, especially since any adsorption layer present at the point of penetration can also be locally overloaded.

[0028] Therefore, there is generally an increased risk that harmful or toxic substances can penetrate the material or protective clothing through the seam, which is a weak point. Hydrophobic or oleophobic treatments of textile materials can, under certain circumstances, cause harmful or toxic substances to bead up or run off the surface of the protective clothing upon contact, thereby also affecting the seam areas and accumulating or agglomerating there. This can lead to local overload in the area of ​​the seam connections between these materials and to a risk of harmful or toxic substances penetrating these areas.

[0029] As previously mentioned, critical areas with regard to the penetration of harmful or toxic substances are located particularly in openings for or through which body parts pass (e.g., arm, leg, or foot openings). This is because, when sewing protective clothing to the other fabric materials, the thread or yarn forming the seam penetrates or perforates these openings, creating weak points, especially given the often high stress on the material at these points. As a result, harmful or toxic substances can penetrate the protective clothing through the opening or along the thread or yarn with relatively little resistance and reach the wearer and / or user of the protective clothing.

[0030] This entails a corresponding risk of excessive exposure of a person located in the danger zone to the harmful or toxic substances in question.

[0031] Seam-based joining of textile materials or sections to create protective clothing can sometimes lead to less than optimal properties regarding the lateral resistance of the materials or layers joined by a seam. This is particularly important because excessive lateral movement of the respective materials or layers of protective clothing in the seam area can create further potential penetration points for harmful or toxic substances. This is especially true since, in a seam-based connection area, the respective materials or layers of the protective clothing can separate or detach from each other, particularly under mechanical stress such as tensile or elongation (sometimes even reversibly). This can allow the ingress of harmful or toxic substances.Furthermore, excessive displacement of corresponding materials or layers forming protective clothing in a connection area of ​​corresponding sections also leads to a further mechanical weakening of an underlying seam connection and a widening or "stretching" of a seam-forming thread or yarn, which can lead to permanent damage to the material.

[0032] Regarding the provision of a stable and durable connection between textile components or cut pieces for the formation of protective clothing or protective clothing items, which also provides a high level of protection against harmful or toxic substances, the corresponding formation is also difficult because protective clothing with ABC or CBRN protection is often formed using multi-layered textile materials based on corresponding components or cut pieces, whereby the multi-layered structure can generally include an outer material and an adsorption filter material.In the joining area, several textile layers must be joined together based on the respective components. These layers generally exhibit different material properties, particularly with regard to their structure and the textile characteristics of the underlying layers. For example, the materials or layers may have different thicknesses, stability properties, or different tensile and elongation resistance. Such differing properties can, under appropriate stress in the joining area, further mechanically stress the seam, posing a further challenge in providing sufficiently stable connections.

[0033] Overall, textile seam designs for joining textile surface materials or sections do ensure a certain, but sometimes not always sufficient, mechanical stability and flexibility. However, with regard to the unwanted penetration of harmful or toxic substances, corresponding points of penetration or weaknesses, i.e., weakening areas, are created, so that such seam connections represent a weakness or impairment with regard to the protective properties against harmful or toxic substances acting on or impacting protective clothing.

[0034] Consequently, and against this background, there is a significant need in the prior art to provide technical solutions for the effective bonding or sealing of critical connection areas in protective clothing against harmful or toxic substances, particularly with regard to the joining of corresponding textile sections or cut pieces, which are often multi-layered. Against this background, there is a significant need in the prior art to provide technical solutions for the effective bonding of respective textile sections or cut pieces for the construction of protective clothing or protective clothing components.

[0035] In this context, there is also a great need to protect the corresponding connection areas of textile components against the entry, breakthrough, or penetration of harmful or toxic substances that come into contact with the material.

[0036] In particular, the state of the art also shows a great need to effectively and mechanically stabilize the connection area of ​​corresponding textile sections or cut parts in transition areas or opening areas (penetration areas) of protective clothing, for example arm or hand openings as well as leg or foot openings or the like, and to protect it against the ingress of harmful or toxic substances.

[0037] As previously mentioned, existing concepts in the prior art often do not provide a satisfactory solution to the underlying problem.

[0038] DE 20 2023 104 799 U1 relates to protective clothing with a protective function against chemical, biological, or radioactive pollutants or toxins, wherein the protective clothing has a first layer in the form of a multi-layered, textile, air-permeable adsorption filter material, a second layer in the form of a textile, air-permeable cover material, and a third layer in the form of a non-textile, air-impermeable filter material; the layers are arranged or positioned overlapping each other in a connection area and are connected to each other by a common seam forming a seam area, wherein at least in the seam area an additional multi-layered, preferably strip-shaped or band-shaped, adsorption filter material is arranged or provided, wherein the additional adsorption filter material is connected to the layers by means of the seam.

[0039] DE 20 2023 105 486 U1 relates to a protective garment with a multi-layered material structure, wherein the multi-layered material structure comprises an outer textile fabric and an inner membrane composite as a moisture barrier, wherein the membrane composite is detachably attached to the outer fabric and comprises a carrier material and a waterproof and water vapor permeable membrane attached to the carrier material, and wherein the membrane composite has a water vapor permeability with a RET value of less than 10.

[0040] Against this background, the present invention aims to provide an efficient technical solution for an effective connection of textile parts or cut pieces in the context of the production of protective clothing or protective clothing items, whereby the disadvantages of the prior art described above are to be largely avoided or at least mitigated.

[0041] In this context, a particular object of the present invention is to provide a textile protective garment which has an ABC protection function (CBRN protection function) and which can preferably be used for civilian and / or military purposes, and which has improved protective and sealing properties against harmful or toxic substances, particularly in the connection area of ​​the individual parts or sections forming the protective garment, based on a textile material that is particularly multi-layered, wherein the connection area is to be efficiently protected against the effects or penetration of harmful or toxic substances while maintaining high mechanical stability, so that the penetration or penetration of such harmful or toxic substances in the connection area of ​​the respective parts, and thus contact of the wearer, is prevented.to prevent the use of such protective clothing by the user in contact with such harmful or toxic substances.

[0042] Furthermore, another object of the present invention is to efficiently protect the connection area of ​​a corresponding protective garment, in which the respective sections meet and are permanently joined to form the protective garment, against the ingress or penetration of harmful or toxic substances acting on the protective garment or the connection area. In particular, the penetration or passage of harmful or toxic substances through seams or connections as such, or through the corresponding connection area, should be prevented or at least significantly reduced.

[0043] In this context, particular attention should be paid to the efficient protection of corresponding connections between textile components of protective clothing or garments in transition or opening areas, such as arm and hand openings, leg and foot openings, or similar features, while ensuring high mechanical stability against the effects or penetration of harmful or toxic substances. Specifically, even under high levels of harmful or toxic substances, the penetration of these substances through seams or similar connections should be prevented.

[0044] Furthermore, an object of the present invention is also to provide a correspondingly durable connection, protected against the effects of harmful or toxic substances, in particular of partial pieces or cut parts based on a multi-layered textile material, wherein textile materials or the underlying layers of the respective materials with different material properties are to be permanently joined with a high level of protection against harmful or toxic substances.

[0045] Furthermore, a further objective of the present invention is to provide appropriate sealing properties against harmful or toxic substances in the underlying connection area of ​​corresponding textile sections or cut pieces, whereby the measures in this regard should not negatively impair wearing comfort or functional properties, for example, with regard to a good fit or high wearing comfort in the transition or opening area for the passage of the extremities of a user or wearer of the protective clothing or garment. Moreover, it should be ensured that the underlying measures result in a durable and mechanically stable seal. In particular, the connection area of ​​corresponding sections should also withstand high mechanical stress in the application or operational scenario while maintaining high flexibility.Being able to resist flexibility.

[0046] Furthermore, a further objective of the present invention is to provide a general technical concept for an efficient connection of textile parts or cut pieces for the formation of protective clothing or a protective clothing item, which can be used for a variety of different designs of the underlying protective clothing or protective clothing item, in particular with regard to corresponding transition or opening areas for receiving or passing through different body parts, such as arm or hand openings as well as leg or foot openings.

[0047] Furthermore, the measures used to solve the underlying problem according to the present invention should be universally adaptable in terms of process and concept and applicable to a large number of specific designs of protective clothing, including with regard to the production of corresponding protective clothing on an industrial scale.

[0048] To solve the problem described above, the present invention therefore proposes – according to a first aspect of the present invention – the protective clothing item according to the invention, in particular with a protective function against chemical, biological or radioactive pollutants and / or toxins, according to claim 1; further advantageous developments and embodiments of this aspect of the invention are the subject of the corresponding dependent claims relating to the protective clothing item according to the invention.

[0049] A further subject matter of the present invention - according to a second aspect of the present invention - is the use of a sewing and / or a joining seam and / or a particularly edge-side joining area of ​​several, in particular at least two, parts (cut pieces) of a multi-layered textile material for equipping a textile protective garment, according to the related independent patent claim.

[0059] In particular, any combination of the features characterizing the invention is also considered disclosed, with embodiments of the same preference for the various features in their combination being preferred (e.g., quantities or quantity ranges of the relevant ingredients of the same preference, or the like). Likewise, all other combinations (i.e., combinations based on different preferences or different levels of preference) are also disclosed.

[0060] Having said that, the present invention will now be described and explained in more detail, also with reference to drawings or figures illustrating preferred embodiments or exemplary embodiments.

[0061] The subject matter of the present invention – according to a first aspect of the present invention – is thus the textile protective garment, in particular with a protective function against chemical and / or biological and / or radioactive harmful and / or toxic substances (warning agents) (“ABC protective function or CBRN protective function”), preferably ABC protective garment (“CBRN protective garment”), preferably for civilian or military purposes, preferably with improved and / or increased displacement resistance of the textile layers of the protective garment. wherein the protective clothing item comprises or is formed from a multi-layered textile material, in particular in the form of a multi-layered textile structure or textile composite, wherein the protective clothing item and / or the multi-layered textile material is / are designed to be air-permeable, the multi-layered textile material - a textile outer material, in particular a flat and / or two-dimensional, air-permeable material, especially a top layer or outer fabric, and - a textile, in particular planar and / or two-dimensional, air-permeable adsorption filter (inner) material, in particular inner layer or inner fabric, in particular for the adsorption of chemical and / or biological and / or radioactive pollutants and / or toxins (warning agents), exhibits or is formed from this wherein the protective clothing item is formed from several, in particular at least two, sections (cut pieces) of the multi-layered textile material, wherein adjacent and / or edge-overlapping sections (cut pieces) are joined together to form the protective clothing piece by sewing and / or by means of a connecting seam, in particular at the edges and / or in a connection area, especially at the edges; wherein the sewing is carried out and / or the connecting seam is designed in such a way that the protective garment is not perforated and / or seamless on the outside, in particular on the outer side facing exposure to chemical and / or biological and / or radioactive hazardous and / or toxic substances, by the sewing and / or the connecting seam, and / or wherein the sewing is carried out in such a way and / or the joining seam is designed in such a way that there is no external seam formed in particular by the joining seam, preferably no external seam formed in particular by the joining seam, located on the outside facing exposure to chemical and / or biological and / or radioactive pollutants and / or toxins, and / or wherein the sewing is carried out in such a way and / or the connecting seam is designed in such a way that the sewing and / or the connecting seam is covered on the outside, in particular in the direction of the action of chemical and / or biological and / or radioactive pollutants and / or toxins, by the outer material, in particular by a part of the outer material (outer material section), preferably by a first part of the outer material.

[0062] A central idea of ​​the present invention is therefore to provide a protective garment with several sewn-together sections, wherein no through-seam is provided, and thus, in the connection area of ​​the sections, at least the outer surface of the protective garment, and preferably also the inner surface, is free of (connecting) seams. In other words, the outer surface of the protective garment, and preferably also the inner surface, is not penetrated by a connecting seam joining the sections.

[0063] The invention thus prevents the outer surface of the protective garment from being weakened by the stitching. This prevents harmful or toxic substances impacting or acting on the protective garment from being channeled or transported inwards along the thread or yarn through the material or the corresponding material arrangement, and in particular from penetrating to a wearer and / or user of the protective garment.

[0064] In the present invention, it is advantageously achieved that no open penetrations are formed through which toxins and / or pollutants could penetrate. This is achieved by the sewing method according to the invention, namely, firstly, by sewing the sections together in an overlapping manner, so that no undesirable penetrations are formed between the sections, and secondly, by ensuring that the outer surface of the protective garment is not penetrated by the seam.

[0065] It has been surprisingly shown that the protective function of the protective garment according to the invention is not, or at least not significantly, impaired by the stitching in the seam or connection area. In particular, the protective garment exhibits a comparable or even identical level of protection in the seam area as in an unstitched area, i.e., an area where the full protective function is present. This is also demonstrated by the exemplary embodiments listed below.

[0066] Furthermore, the present invention allows the protective clothing garment to be advantageously designed to be as resistant to displacement and / or shifting as possible, particularly in the connection area. This means, in particular, that the various interconnected materials or components are not (excessively) displaceable relative to one another. This is advantageous because it prevents potential penetration points for harmful and / or toxic substances from arising due to unwanted displacement of the materials or components. It also prevents the seam from being subjected to excessive stress due to unwanted displacement, which can lead to weakening and ultimately permanent damage, such as stretching, loosening, or even tearing of the seam.

[0067] According to the invention, high stability and a secure fit of the protective clothing on the body of a user and / or wearer are also ensured. This is advantageous in order to prevent the penetration of harmful and / or toxic substances at critical points such as openings for extremities or arms, legs and / or the neck, and in particular to ensure a close fit of the protective clothing at these points.

[0068] At the same time, the present invention also enables a high level of wearing comfort and / or high flexibility and / or elasticity of the protective clothing item, even in the connection area. In particular, sealing measures that stiffen the material, such as gluing or welding the seam, can be dispensed with. Additional materials such as sealing tapes can also be advantageously omitted.

[0069] The protective clothing item according to the invention can also offer good air permeability and / or be breathable, in particular without (significantly) impairing its protective function. This, in turn, advantageously increases wearing comfort.

[0070] The present invention, particularly the use of sewing to join the individual sections, enables a reliable and durable connection, even under mechanical stress, which cannot be achieved with other joining techniques such as stapling, tacking, or gluing. At the same time, the seam connection according to the invention overcomes the disadvantages of seam connections known from the prior art, especially the impairment of the protective function. Specifically, the seam according to the invention does not create a penetration on the outside of the protective garment or a "bridge" through or over which toxic and / or harmful substances can penetrate. Furthermore, wearer comfort is not affected, particularly because sealing measures such as sealing tapes or the use of a welded seam are unnecessary.

[0071] The protective garment according to the invention thus enables a surprisingly and advantageously high and lasting protective function, even in the area of ​​the sewing, while simultaneously offering a high level of wearing comfort.

[0072] The terms "outer" and "external" used in the context of the present invention refer in particular to the side of the protective garment facing away from the user and / or wearer when worn or in use (the outermost side of the protective garment). This is especially the side of the protective garment that is or may be directly exposed to chemical, biological, and / or radioactive pollutants and / or toxins. In particular, the outer side is formed by the outer material, namely the side of the outer material facing away from the user and / or wearer and / or from the adsorption filter (inner) material when the protective garment is worn or in use.

[0073] Accordingly, "inside" and "inner side" refer specifically to the side of the protective garment facing the user and / or wearer when worn or in use (the innermost side of the protective garment). This is, in particular, the side of the protective garment that, when worn or in use, is in direct contact with or directly adjacent to the wearer's and / or user's body. Specifically, the inner side is formed by the adsorption filter material, namely the side of the adsorption filter material facing away from the user and / or wearer and / or the outer material, preferably by the textile backing layer of the adsorption filter material, which will be defined below.

[0074] In this sense, an "outer seam" is, in particular, a seam that, at least partially, encompasses and / or penetrates the outer surface or is (also) located on the outer surface. According to the invention, the joining seam (and in particular the closing seams listed below) does not constitute such an outer seam, or rather, the joining seam (and in particular the closing seams listed below) is not designed as an outer seam.

[0075] The terms "seamless" and "perforation-free" refer in particular to the connecting seam, and possibly also to the closure seams listed below, and especially to the essential seams and / or seams that substantially join the individual sections. A seamless and / or perforation-free side is therefore, in particular, a side that is free of the connecting seam and, where applicable, closure seams. However, this does not preclude the side from having further seams, especially stabilizing seams, such as topstitching or the like. Such seams, however, do not impair, or at least not significantly impair, the protective function of the protective garment.

[0076] The present invention is described below with reference to preferred embodiments and illustrative drawings and figures, the descriptions of which apply to all aspects of the invention and in which the corresponding preferred embodiments and configurations of the present invention are in no way limiting; further advantages, properties, aspects and features of the present invention are also shown in the description of the figures.

[0077] The depictions of figures show: Fig. 1 a schematic, partial cross-sectional representation of the protective clothing piece according to the invention in the connection area according to a first embodiment according to the invention, in which the parts of the multilayer textile material of the protective clothing piece are connected to each other (only) by means of the connecting seam; Fig. 2 a further schematic, partial cross-sectional representation of the protective clothing piece according to the invention in the connection area according to a second embodiment according to the invention, in which the parts of the multilayer textile material of the protective clothing piece are connected to each other by closing seams in addition to the connecting seam; Fig. 3 schematic close-up views of the adsorption filter (inner) material with respective configurations of a layer structure of the adsorption filter (inner) material, according to which the adsorption filter (inner) material can have a two-, three- or four-layer structure; Fig. 4 a schematic (overall) view of a piece of protective clothing according to the invention, for example in the form of a protective suit.

[0078] The figure depictions according to Fig. 1 to Fig. Figure 4 illustrates in particular the first aspect of the present invention, namely, according to which a textile protective garment 1, in particular with a protective function against chemical and / or biological and / or radioactive pollutants and / or toxins (warning agents) (“ABC protective function” or CBRN protective function”), preferably an ABC protective garment (“CBRN protective garment”), preferably for civilian or military purposes, is proposed, wherein the protective garment 1 comprises or is formed from a multi-layered textile material 2, in particular in the form of a multi-layered textile structure or textile composite, wherein the protective garment 1 and / or the multi-layered textile material 2 is / are designed to be air-permeable. where the multilayered textile material 2 - a textile outer material, in particular a planar and / or two-dimensional, air-permeable outer material 3, in particular a top layer or outer fabric, and - a textile, in particular planar and / or two-dimensional, air-permeable adsorption filter (inner) material 4, in particular inner layer or inner fabric, in particular for the adsorption of chemical and / or biological and / or radioactive pollutants and / or toxins (warning agents), exhibits or is formed from this wherein the protective clothing item 1 is formed from several, in particular at least two, sections (cut pieces) A, B of the multi-layered textile material 2, wherein adjacent and / or edge-overlapping sections (cut pieces) A, B are joined together to form the protective clothing piece 1 by means of sewing and / or by means of a connecting seam 5, in particular at the edge and / or in a connecting area 6, in particular at the edge; wherein the sewing is carried out in such a way and / or the connecting seam 5 is designed in such a way that the protective garment 1 is not perforated and / or seamless on the outside, in particular on the outer side facing exposure to chemical and / or biological and / or radioactive hazardous and / or toxic substances, by the sewing and / or by the connecting seam 5, and / or wherein the sewing is carried out in such a way and / or the connecting seam 5 is designed in such a way that there is no external seam formed in particular by the connecting seam 5, preferably no external seam arranged on the outside facing the action of chemical and / or biological and / or radioactive pollutants and / or toxins, in particular formed by the connecting seam 5, and / or wherein the sewing is carried out in such a way and / or the connecting seam 5 is designed in such a way that the sewing and / or the connecting seam 5 is covered on the outside, in particular in the direction of the action of chemical and / or biological and / or radioactive pollutants and / or toxins, by the outer material 3, in particular by an outer material section (outer material cut part) 3A, 3B, preferably by a first outer material section 3A.

[0079] According to the invention, it may be provided, for example, in Fig. 1 and Fig. 2 shows that the first section (cut part) A has or consists of a first outer material section 3A [first outer material cut part 3A or outer material section 3A of the first section A] and a first adsorption filter (inner) material section 4A [first adsorption filter (inner) material cut part 4A or adsorption filter (inner) material section 4A of the first section A].

[0080] According to the invention, it can also be provided that the second section (cut part) B has or consists of a second outer material section 3B [second outer material cut part 3B or outer material section 3B of the second section B] and a second adsorption filter (inner) material section 4B [second adsorption filter (inner) material cut part 4B or adsorption filter (inner) material section 4B of the second section B].

[0081] In particular, according to the invention, it can be provided that in the area of ​​sewing and / or in the area of ​​the connecting seam 5, preferably in the connecting area 6, (only) one of the parts A or B of the outer material 3, in particular (only) the first outer material part 3A, has an outer material folding section 3A' [outer material folding section 3A' of the first outer material part 3A], in particular an outer material folding section 3A' extending along the edge and / or extending along the edge, as shown in Fig. 1 illustrates.

[0082] Furthermore, according to the invention, it can be provided that in the area of ​​sewing and / or in the area of ​​the connecting seam 5, preferably in the connecting area 6, (only) one of the parts A or B of the outer material 3, in particular (only) the first outer material part 3A, is folded over, in particular folded over at the edge, preferably directed inwards at the edge and / or inwards, in particular with respect to the multilayer textile material 2, and / or folded over in the direction of the adsorption filter (inner) material 4, in particular forming a first outer material folding section 3A' [outer material folding section 3A' of the first outer material part 3A], in particular a first outer material folding section 3A' running along the edge and / or extending along the edge.

[0083] The terms "inward" and "directed inwards" refer specifically to the multilayer textile material 2, meaning directed towards the interior of the multilayer textile material 2. An inwardly and / or inwardly directed folding section, in particular the outer material folding section 3A' and / or an adsorption filter (inner) material folding section 4A' defined below, is therefore folded or turned inwards into the interior of the multilayer textile material 2 and / or is located within the interior of the multilayer textile material 2. The terms "inward" and "directed inwards" should not be confused with the term "inside," which, as defined above, refers to the side of the textile material 2 facing the user and / or wearer, and thus specifically does not refer to a section located within the interior of the multilayer textile material 2.

[0084] In this context, the folded (folded) section A or B of the outer material 3, in particular the folded first outer material section 3A, may have an unfolded and / or unfolded outer material section 3A'' [unfolded and / or unfolded outer material section 3A'' of the first outer material section 3A], as e.g. in Fig. 1 shown. In particular, the unfolded and / or unfolded outer material section 3A'' can form the section located on the outside and / or facing the effects of chemical and / or biological and / or radioactive pollutants and / or toxins and / or the outside of the outer material 3.

[0085] With regard to the outer material folding section 3A' and / or the non-folded outer material section 3A'', the protective clothing piece 1 according to the invention may furthermore have one or more of the following properties: - In particular, it may be provided that the outer material folding section 3A' is directed inwards and / or lies inwards, especially with regard to the multilayer textile material 2, and / or is designed and / or arranged towards the adsorption filter (inner) material 4. - In addition, the outer material folding section 3A' can be arranged on the side of the unfolded and / or unfolded outer material section 3A'' of the first outer material part 3A that is away from exposure to chemical and / or biological and / or radioactive pollutants and / or toxins. - Furthermore, the outer material folding section 3A' can be covered on the outside, in particular in the direction of the side of the protective clothing item 1 facing the effects of chemical and / or biological and / or radioactive harmful and / or toxic substances and / or in the direction of the side of the protective clothing item 1 facing away from a user and / or wearer, by the unfolded and / or unfolded outer material section 3A'' of the first outer material part 3A.

[0086] In this sense, the outer material folding section 3A' does not form part or section of the outer surface of the protective garment 1. The outer material folding section 3A' is located inwards within the textile material 2 and / or directed inwards into the textile material 2 and / or is covered by the unfolded outer material section 3A'', and thus is not on the outside of the protective garment 1. In the area of ​​the outer material folding section 3A', the outer surface of the protective garment 1 is formed in particular by the unfolded outer material section 3A'', which covers or overlaps the outer material folding section 3A' (on the outside).

[0087] According to the invention, it can be provided that in the area of ​​sewing and / or in the area of ​​the connecting seam 5, preferably in the connecting area 6, (only) one of the adjacent parts A or B of the outer material 3, in particular (only) the part A or B of the outer material 3 that differs from the folded-over part A or B of the outer material 3 and / or in particular (only) the second outer material part 3B, is not folded over.

[0088] Furthermore, according to the invention, in the area of ​​sewing and / or in the area of ​​the connecting seam 5, preferably in the connecting area 6, (only) one of the adjacent parts A or B of the outer material 3, in particular (only) the part A or B of the outer material 3 that differs from the folded-over part A or B of the outer material 3 and / or in particular (only) the second outer material part 3B, can have a free and / or not folded (folded over) and / or fold-free (fold-free) extension end section on the edge side.

[0089] According to the invention, the sewing can be carried out and / or the connecting seam 5 can be designed such that the sewing and / or the connecting seam 5 is covered on the inside, in particular in the direction of a user and / or wearer of the protective clothing item 1 and / or in particular on the side facing away from the effects of chemical and / or biological and / or radioactive pollutants and / or toxins (inside) of the protective clothing item 1, by the adsorption filter (inner) material 4, in particular by an adsorption filter (inner) material section (adsorption filter (inner) material section) 4A, 4B, preferably by a first adsorption filter (inner) material section 4A.

[0090] In particular, according to the invention, it can be provided that in the area of ​​the sewing and / or in the area of ​​the connecting seam 5, preferably in the connection area 6, (only) one of the sections A or B of the adsorption filter (inner) material 4, in particular the first adsorption filter (inner) material section 4A, has an adsorption filter (inner) material folding section 4A' [adsorption filter (inner) material folding section 4A' of the first adsorption filter (inner) material section 4A], in particular an adsorption filter (inner) material folding section 4A' extending along the edge and / or extending along the edge, as shown in Fig. 1 illustrates.

[0091] Furthermore, according to the invention, it can be provided that in the area of ​​sewing and / or in the area of ​​the connecting seam 5, preferably in the connecting area 6, (only) one of the parts A or B of the adsorption filter (inner) material 4, in particular (only) the first adsorption filter (inner) material part 4A, is folded over, in particular is folded over at the edge, preferably directed inwards at the edge and / or inwards, in particular with respect to the multilayer textile material 2, and / or is folded over in the direction of the outer material 3, in particular forming an adsorption filter (inner) material folding section 4A' [adsorption filter (inner) material folding section 4A' of the first adsorption filter (inner) material part 4A].

[0092] In this context, the flipped (reversed) section A or B of the adsorption filter (inner) material 4, in particular the flipped first adsorption filter (inner) material section 4A, may have a non-flipped and / or non-reversed adsorption filter (inner) material section 4A'', as e.g. in Fig. 1 shown. In particular, the unfolded and / or unfolded adsorption filter (inner) material section 4A'' can form the inner section of the adsorption filter (inner) material 4, which is located on the inside and / or faces a user and / or wearer of the protective clothing item 1.

[0093] With regard to the adsorption filter (inner) material folding section 4A' and / or the non-folded adsorption filter (inner) material section 4A'', the protective clothing piece 1 according to the invention may furthermore have one or more of the following properties: - In particular, it may be provided that the adsorption filter (inner) material folding section 4A' is directed inwards and / or lies inwards, especially with regard to the multilayer textile material 2, and / or is designed and / or arranged towards the outer material 3. - In addition, the adsorption filter (inner) material turning section 4A' can be arranged on the side of the unturned and / or unturned adsorption filter (inner) material section 4A'' of the first adsorption filter (inner) material section 4A that faces the effects of chemical and / or biological and / or radioactive pollutants and / or toxins. - Furthermore, the adsorption filter (inner) material folding section 4A' can be covered on the inside, in particular in the direction of the side of the protective clothing 1 facing away from the effects of chemical and / or biological and / or radioactive pollutants and / or toxins and / or in the direction of the side of the protective clothing 1 facing a user and / or wearer, by the unfolded and / or unfolded adsorption filter (inner) material section 4A'' of the first adsorption filter (inner) material part 4A.

[0094] In this sense, the adsorption filter (inner) material folding section 4A' does not form part or section of the inside of the protective garment 1. The adsorption filter (inner) material folding section 4A' is located inwards within the textile material 2 and / or directed inwards into the textile material 2 and / or is covered by the unfolded adsorption filter (inner) material section 4A'', and is therefore not located on the inside of the protective garment 1. In the area of ​​the adsorption filter (inner) material folding section 4A', the inside of the protective garment 1 is formed in particular by the unfolded adsorption filter (inner) material section 4A'', which covers or overlaps the adsorption filter (inner) material folding section 4A' (on the inside).

[0095] According to the invention, it can be provided that in the area of ​​the sewing and / or in the area of ​​the connecting seam 5, preferably in the connecting area 6, (only) one of the adjacent sections A or B of the adsorption filter (inner) material 4, in particular (only) the section A or B of the adsorption filter (inner) material 4 that differs from the folded-over section A or B of the adsorption filter (inner) material 4 and / or in particular (only) the adsorption filter (inner) material section 4B of the second section B [second adsorption filter (inner) material section 4B], is not folded over.

[0096] Furthermore, according to the invention, in the area of ​​the sewing and / or in the area of ​​the connecting seam 5, preferably in the connection area 6, (only) one of the adjacent sections A or B of the adsorption filter (inner) material 4, in particular (only) the section A or B of the adsorption filter (inner) material 4 that differs from the folded-over adsorption filter (inner) material 4 of one of the sections A or B and / or in particular (only) the adsorption filter (inner) material section 4B of the second section B [second adsorption filter (inner) material section 4B], can have a free and / or unfolded (folded over) and / or unfolded (fold-over-free) extension end section on the edge.

[0097] In a particularly preferred or advantageous embodiment, such as in Fig. Figure 1 shows several of the features described above, which can in principle be implemented independently. In particular, the especially preferred embodiment provides that - that in the area of ​​sewing and / or in the area of ​​the connecting seam 5, preferably in the connection area 6, the first outer material section 3A is folded over, in particular folded over at the edge, preferably directed inwards at the edge and / or inwards, in particular with respect to the multilayer textile material 2, and / or folded over in the direction of the adsorption filter (inner) material 4, in particular forming a first outer material folding section 3A' [outer material folding section 3A' of the first outer material section 3A], in particular a first outer material folding section 3A' running along the edge and / or extending along the edge; and - that in the area of ​​the sewing and / or in the area of ​​the connecting seam 5, preferably in the connecting area 6, the outer material 3 is not folded over (not folded over) and / or has a free and / or not folded over (not folded over) and / or unfolded (unfolded) extension end section at the edge; and - that in the area of ​​sewing and / or in the area of ​​the connecting seam 5, preferably in the connection area 6, the first adsorption filter (inner) material section 4A is folded over, in particular folded over at the edge, preferably directed inwards at the edge and / or inwards, in particular with respect to the multilayer textile material 2, and / or folded over in the direction of the outer material 3, in particular forming an adsorption filter (inner) material folding section 4A; and - that in the area of ​​the sewing and / or in the area of ​​the connecting seam 5, preferably in the connecting area 6, the adsorption filter (inner) material 4 (the adsorption filter (inner) material section 4B of the second section B [second adsorption filter (inner) material section 4B]) is not folded over; and / or has a free and / or not folded over and / or unfolded extension end section on the edge.

[0098] With regard to the arrangement, positioning and / or sequence of the materials 3, 4, in particular the sections 3A, 3B, 4A, 4B and / or their overlapping sections 3A', 4A', the protective clothing piece 1 may have one or more of the following properties: - According to the invention, the outer material 3 can be arranged and / or positioned on the outside, in particular on the side (outside) of the protective clothing 1 facing the effects of chemical and / or biological and / or radioactive pollutants and / or toxins and / or on the side (outside) of the protective clothing 1 facing away from a wearer and / or user of the protective clothing 1. - In addition, according to the invention, the adsorption filter (inner) material 4 can be arranged and / or positioned on the inside, in particular on the side (inside) of the protective garment 1 facing away from the effects of chemical and / or biological and / or radioactive pollutants and / or toxins and / or on the side (inside) of the protective garment 1 facing a wearer and / or user of the protective garment 1. - Furthermore, it may be provided that in the area of ​​sewing and / or in the area of ​​the connecting seam 5, preferably in the connecting area 6, the second outer material section 3B and the second adsorption filter (inner) material section 4B are enclosed and / or encompassed by the first outer material section 3A, in particular the outer material folding section 3A', and the first adsorption filter (inner) material section 4A, in particular the adsorption filter (inner) material folding section 4A'. - In particular, according to the invention, it can be provided that in the area of ​​sewing and / or in the area of ​​the connecting seam 5, preferably in the connecting area 6, the materials 3, 4 or the relevant sections are arranged and / or positioned in the following sequence: (i) first outer material section 3A, in particular outer material folding section 3A', (ii) second outer material section 3B, (iii) second adsorption filter (internal) material section 4B, (iv) first adsorption filter (internal) material section 4A, in particular adsorption filter (internal) material folding section 4A', in particular in a sequence or order from outside to inside. - In addition, it may be provided that the outer material folding section 3A', in particular with the sewing and / or the connecting seam 5, is covered by the unfolded and / or unfolded outer material section 3A'' and / or that the outer material folding section 3A' is covered by the unfolded and / or unfolded outer material section 3A'' on the outside, in particular in the direction of the action of chemical and / or biological and / or radioactive pollutants and / or toxins.

[0099] In this context, it may further be provided that the adsorption filter (inner) material folding section 4A', in particular including the stitching and / or the connecting seam 5, is covered by the unfolded and / or unfolded adsorption filter (inner) material section 4A''. Furthermore, it may be provided in this context that the adsorption filter (inner) material folding section 4A', in particular including the stitching and / or the connecting seam 5, is covered on the inside by the unfolded and / or unfolded adsorption filter (inner) material section 4A'', in particular on the side of the protective garment 1 facing away from exposure to chemical and / or biological and / or radioactive pollutants and / or toxins, and / or on the side of the protective garment 1 facing a user and / or wearer.

[0100] According to the invention, preferably in the connection area 6, the first outer material section 3A, in particular the outer material folding section 3A'; the second outer material section 3B; the second adsorption filter (inner) material section 4B; and the first adsorption filter (inner) material section 4A, in particular the adsorption filter (inner) material folding section 4A', can be connected to each other by sewing and / or by means of the connecting seam 5, as shown in Fig. 1 illustrates.

[0101] Furthermore, according to the invention, preferably in the connection area 6, the outer material folding section 3A'; the second outer material section 3B; the second adsorption filter (inner) material section 4B; and the adsorption filter (inner) material folding section 4A' can be connected to each other by sewing and / or by means of the connecting seam 5.

[0102] According to the invention, it can be provided that the connecting seam 5 encompasses and / or connects the first outer material section 3A, in particular the outer material folding section 3A'; the second outer material section 3B; the second adsorption filter (inner) material section 4B; and the first adsorption filter (inner) material section 4A, in particular the adsorption filter (inner) material folding section 4A'.

[0103] Furthermore, according to the invention, it can be provided that the connecting seam 5 encompasses and / or connects the outer material folding section 3A'; the second outer material section 3B; the second adsorption filter (inner) material section 4B; and the adsorption filter (inner) material folding section 4A'.

[0104] In particular, according to the invention it can be provided that the unfolded and / or unfolded outer material section 3A'', in particular the unfolded and / or unfolded outer material section 3A'' and the unfolded and / or unfolded adsorption filter (inner) material section 4A'', is not captured and / or not penetrated by the connecting seam 5.

[0105] In particular, according to the invention, the unfolded and / or unfolded outer material section 3A'', in particular the unfolded and / or unfolded outer material section 3A'') and the unfolded and / or unfolded adsorption filter (inner) material section 4A'', are designed seamlessly and / or without perforations.

[0106] In a particularly preferred embodiment, as in Fig. As illustrated in Figure 1, it can be provided that the connecting seam 5 encompasses and / or connects the outer material folding section 3A', the second outer material section 3B, the second adsorption filter (inner) material section 4B, and the adsorption filter (inner) material folding section 4A', and that the unfolded and / or unfolded outer material section 3A'', in particular the unfolded and / or unfolded outer material section 3A'' and the unfolded and / or unfolded adsorption filter (inner) material section 4A'', are seamless and / or without penetrations and / or are not encompassed and / or penetrated by the connecting seam 5.

[0107] The measures described above, in particular the folding over of the outer material section 3A and the sewing of only the inwardly facing outer material folding section 3A', ensure in a particularly simple way that the outer surface (outermost side) of the protective clothing item 1, in particular the outer material 3, i.e. the side that is directly exposed to the effects of chemical and / or biological and / or radioactive pollutants and / or toxins, is not penetrated by the sewing or the connecting seam 5, which brings about the advantages described above, in particular ensuring the high level of protection.

[0108] In preferred embodiments, as described above, the inner side (innermost side) of the protective garment 1, in particular the adsorption filter (inner) material 4, i.e., the side directly facing the user and / or wearer and / or in contact with their body, is not penetrated by the sewing or the connecting seam 5, specifically by folding over the adsorption filter (inner) material section 4A and sewing only the inwardly facing adsorption filter (inner) material folding section 4A'. This has the additional advantage of double protection. Even if harmful substances and / or toxins penetrate the outer material 3, the adsorption filter (inner) material 4 forms a further barrier for the harmful substances and / or toxins, which, due to the seamless construction, remains unbroken and therefore secure.

[0109] According to the invention, the connecting seam 5 can be produced or formed by sewing, in particular using at least one yarn and / or thread, and / or the sewing is carried out using at least one yarn and / or thread. This ensures a load-bearing and therefore stable connection between the respective materials or sections.

[0110] In particular, the connecting seam 5 can be produced or formed by repeatedly passing at least one yarn and / or thread through the materials 3, 4, in particular through the outer material folding section 3A', the second outer material section 3B, the second adsorption filter (inner) material section 4B and the adsorption filter (inner) material folding section 4A'.

[0111] According to the invention, the sewing can be carried out by repeatedly guiding at least one yarn and / or thread through the materials 3, 4, in particular through the outer material folding section 3A', the second outer material section 3B, the second adsorption filter (inner) material section 4B and the adsorption filter (inner) material folding section 4A'.

[0112] In general, according to the invention, the yarn and / or thread of the connecting seam 5 may comprise or consist of a material, in particular a textile fiber material, from the group consisting of natural materials and synthetic materials, preferably selected from the group consisting of cotton; wool; linen; polyesters; polyolefins; polyvinyl chlorides; polyvinylidene chlorides; acetates, in particular cellulose acetates; triacetates, in particular cellulose triacetates; polyacrylic; polyamides; polyvinyl alcohols; polyurethanes; polyvinyl esters; viscose; and mixtures or combinations thereof.

[0113] According to the invention, in this context the yarn and / or thread of the connecting seam 5 and / or the yarn and / or thread used for sewing can be designed as a monofilament yarn or as a multifilament yarn.

[0114] The multifilament yarn can be based on corresponding single filaments.

[0115] The special seam design, as provided for in the present invention, can in particular avoid the use of adhesives to join the respective components in the joint area or the formation of welds or the like. In particular, this avoids the disadvantages associated with the use of adhesives or welds, such as insufficient flexibility or elasticity and sometimes inadequate stability, for example, due to material incompatibilities or the like.

[0116] Against this background, it is therefore particularly provided according to the invention that the connecting seam 5 is not designed as an adhesive seam (adhesive connection or adhesive connection seam) and / or has at least substantially no adhesive and / or is not formed by bonding the materials 3, 4, in particular the outer material folding section 3A', the second outer material section 3B, the second adsorption filter (inner) material section 4B and the adsorption filter (inner) material folding section 4A'.

[0117] Likewise, according to the invention, it is particularly provided that the connecting seam 5 is not formed as a weld seam and / or is not formed by welding the materials 3, 4, in particular the outer material folding section 3A', the second outer material section 3B, the second adsorption filter (inner) material section 4B, and the adsorption filter (inner) material folding section 4A'.

[0118] In a preferred embodiment, in particular as described in Fig. 2 shown, according to the invention, preferably in the connection area 6, in particular in addition to the connecting seam 5, at least one closing seam 7, 8, in particular two closing seams 7, 8, preferably an outer material closing seam 7 and / or an inner material closing seam 8, is present.

[0119] In this context, according to the invention, it can be provided that, preferably in the connection area 6, an outer material closing seam 7 (first closing seam) is present. In particular, the outer material closing seam 7 engages and / or penetrates and / or connects the first outer material section 3A of the first section A, in particular the outer material folding section 3A', and the second outer material section 3B of the second section B, in particular the free and / or unfolded (folded) and / or unfolded (unfolded) extension end section of the second outer material section 3B.

[0122] Furthermore, according to the invention, an inner material closing seam (second closing seam, adsorption filter (inner) material closing seam) 8 can be provided in the connection area 6. In particular, the inner material closing seam 8 engages and / or penetrates and / or connects the first adsorption filter (inner) material section 4A of the first section A, in particular the adsorption filter (inner) material folding section 4A', and the second adsorption filter (inner) material section 4B of the second section B, in particular the free and / or unfolded (folded) and / or unfolded (fold-free) extension end section of the second adsorption filter (inner) material section 4B.

[0126] However, even if the connecting seam 5 joins all sections 3A, 3B, 4A, and 4B together, the outer material closing seam 7 and / or the inner material closing seam 8 can be provided and advantageous. The outer material closing seam 7 and / or the inner material closing seam 8 can thus advantageously relieve the connecting seam 5, particularly with regard to forces acting in the direction of the connecting seam 5. Furthermore, the outer material closing seam 7 can (additionally) close and / or seal the area between the outer material folding section 3A' and the second outer material section 3B, and / or the inner material closing seam 8 can (additionally) close and / or seal the area between the adsorption filter (inner) material folding section 4A' and the second adsorption filter (inner) material section 4B, and / or contribute to a closer fit of this area to the body of a user / wearer.This is advantageous in preventing the ingress of toxins and / or pollutants. Furthermore, the outer material closure seam 7 and / or the inner material closure seam 8 can contribute to a shift-free fixation, in particular ensuring that the folded area and / or the folded section 3A' or 4A' cannot be displaced. The outer material closure seam 7 and / or the inner material closure seam 8 thus contribute to a high degree of stability in the connection or seam.

[0127] In this context, it can further be provided according to the invention that the outer material closure seam 7 and / or the inner material closure seam 8, in particular identical or different and / or independent of each other, is / are designed such that the protective garment 1 is seamless and / or perforation-free on the outside, in particular on the outer side facing exposure to chemical and / or biological and / or radioactive pollutants and / or toxins, and / or is not perforated by the outer material closure seam 7 and / or the inner material closure seam 8.

[0128] In this regard, it may be provided that the outer material closure seam 7 and / or the inner material closure seam 8, in particular identical or different and / or independent of each other, is / are designed in such a way that there is no outer seam (seam penetrating the outer surface) arranged on the outside surface facing the action of chemical and / or biological and / or radioactive pollutants and / or toxins, in particular formed by the outer material closure seam 7 and / or the inner material closure seam 8.

[0129] Furthermore, it can be such that the outer material closure seam 7 and / or the inner material closure seam 8, in particular identical or different and / or independent of each other, is / are designed in such a way that the outer material closure seam 7 and / or the inner material closure seam 8 is / are covered on the outside, in particular in the direction of the action of chemical and / or biological and / or radioactive pollutants and / or toxins, by the outer material 3, in particular by the outer material section (outer material cut part) 3A, 3B, preferably by the first outer material section 3A.

[0130] In other words, the same advantageous features according to the invention apply to the outer seam 7 and / or the inner seam 8 with respect to the outside of the protective garment 1 as to the connecting seam 5, namely that the outer seam 7 and / or the inner seam 8 do not penetrate the outside or form an outer seam, or are covered on the outside. With regard to the advantages of this design of the outer seam 7 and / or the inner seam 8, reference can also be made to the descriptions of the connecting seam 5, which apply accordingly.

[0131] Furthermore, according to the invention, it can be provided that the outer material closure seam 7 and / or the inner material closure seam 8, in particular identical or different and / or independent of each other, is / are designed such that the outer material closure seam 7 and / or the inner material closure seam 8, on the inside, in particular on the side facing away from the effects of chemical and / or biological and / or radioactive pollutants and / or toxins (inside) of the protective clothing piece 1, is / are covered by the adsorption filter (inner) material 4, in particular by the adsorption filter (inner) material section (adsorption filter (inner) material section) 4A, 4B, preferably by the first adsorption filter (inner) material section 4A.

[0133] Preferably, in addition to the outer surface of the protective garment 1, the inner surface of the protective garment 1 is also not affected or penetrated by the outer material closure seam 7 and / or the inner material closure seam 8. As previously described, the connecting seam 5 also preferably does not affect or penetrate the inner surface of the protective garment 1. Thus, the inner surface is preferably also seamless, particularly with regard to the connecting seam 5, the outer material closure seam 7, and the inner material closure seam 8. Regarding the advantages of this design of the outer closure seam 7 and / or the inner closure seam 8, reference can also be made to the explanations concerning the connecting seam 5, which apply accordingly here. In particular, double protection is enabled, since unbroken barriers against harmful and / or toxic substances are formed on both the outer and inner surfaces.

[0134] With regard to the arrangement and / or positioning of the outer material closure seam 7 relative to the connecting seam 5, the protective clothing piece 1 or the outer material closure seam 7 can have one or more of the following properties: - Thus, the outer material closing seam 7 can extend at least essentially parallel to the connecting seam 5. - In addition, the outer material closing seam 7 can be offset and / or spaced apart from the connecting seam 5, in particular in the direction orthogonal to the longitudinal extent of the connecting seam 5 and / or in the direction of the non-free end of the outer material folding section 3A'. - Furthermore, it may be provided that the outer material closing seam 7 has a greater distance to the free end of the outer material folding section 3A' than the joining seam 5; and / or that the outer material closing seam 7 is arranged closer to the non-free end of the outer material folding section 3A' than the joining seam 5. - Furthermore, it can be the case that the outer material closing seam 7 is arranged in the area of ​​the non-free end of the outer material folding section 3A', in particular wherein the connecting seam 5 is arranged in the area of ​​the free end of the outer material folding section 3A'.

[0135] The term "non-free end" of the outer material folding section 3A' refers in particular to the point where the outer material folding section 3A' transitions into the unfolded outer material section 3A'', specifically the point where the outer material 3 is folded over. The free end of the outer material folding section 3A' is accordingly the end of the outer material folding section 3A' opposite the non-free end, which also forms the free end of the outer material segment 3A.

[0136] With regard to the arrangement and / or positioning of the inner material closure seam 8 relative to the connecting seam 5, the protective clothing piece 1 or the inner material closure seam 8 can have one or more of the following properties: - Thus, the inner material closing seam 8 can extend at least essentially parallel to the connecting seam 5. - In addition, the inner material closing seam 8 can be offset and / or spaced apart from the connecting seam 5, in particular in the direction orthogonal to the longitudinal extent of the connecting seam 5 and / or in the direction of the non-free end of the adsorption filter (inner) material folding section 4A'. - Furthermore, it may be provided that the inner material closing seam 8 has a greater distance to the free end of the adsorption filter (inner) material folding section 4A' than the connecting seam 5 and / or that the inner material closing seam 8 is arranged closer to the non-free end of the adsorption filter (inner) material folding section 4A' than the connecting seam 5. - Furthermore, it can be the case that the inner material closing seam 8 is arranged in the area of ​​the non-free end of the adsorption filter (inner) material folding section 4A', in particular wherein the connecting seam 5 is arranged in the area of ​​the free end of the adsorption filter (inner) material folding section 4A'.

[0137] The non-free end of the adsorption filter (inner) material folding section 4A' refers in particular to the point where the adsorption filter (inner) material folding section 4A' transitions into the non-folded adsorption filter (inner) material section 4A'', specifically the point where the adsorption filter (inner) material 4 is folded over. The free end of the adsorption filter (inner) material folding section 4A' is accordingly the end of the adsorption filter (inner) material folding section 4A' opposite the non-free end, which also forms the free end of the adsorption filter (inner) material segment 4A.

[0138] With regard to the arrangement and / or positioning of the outer material closure seam 7 and the inner material closure seam 8 relative to each other and / or together with the connecting seam 5, the protective clothing piece 1 can have one or more of the following properties: - The outer material closing seam 7 and the inner material closing seam 8 can be arranged on the same side of the connecting seam 5, in particular on the side facing the non-free end of the outer material folding section 3A' and / or the adsorption filter (inner) material folding section 4A' or on the side facing away from the free end of the outer material folding section 3A' and / or the adsorption filter (inner) material folding section 4A'. - In addition, the outer material closure seam 7 and the inner material closure seam 8 can extend at least substantially parallel to each other. - Furthermore, the outer material closing seam 7 and the inner material closing seam 8 can be arranged offset from each other and / or spaced apart from each other, in particular in the direction orthogonal to their longitudinal extent and / or to the longitudinal extent of the connecting seam 5. - In this regard, it may be provided that the distance between the outer material closing seam 7 and the connecting seam 5 is greater than the distance between the inner material closing seam 8 and the connecting seam 5. - In particular, it may be provided that, starting from the free end of the outer material folding section 3A' and / or the adsorption filter (inner) material folding section 4A', the seams are arranged in the series and / or sequence (i) joining seam 5, (ii) inner material closing seam 8 and (iii) outer material closing seam 7.

[0139] The previously described arrangements and / or positions of the outer material closure seam 7, inner material closure seam 8, and / or connecting seam 5 are particularly advantageous, especially for increasing the stability of the seam and / or for further improving the protective function in the area of ​​the seam or in the connection area 6. For example, by arranging the outer seam closure seam 7 in the area of ​​the non-free end of the outer material fold-over section 3A', a passage opening extending to the connecting seam 5 between the outer material fold-over section 3A' and the second section 3B can be closed. Furthermore, the offset arrangement of the seams 5, 7, and / or 8 further increases the slip resistance.

[0140] According to the invention, the outer material closure seam 7 and / or the inner material closure seam 8, in particular identical or different and / or independent of each other, can be produced and / or formed by sewing, especially using at least one yarn and / or thread. This ensures a load-bearing and therefore stable connection between the respective materials or sections.

[0141] In particular, the outer material closing seam 7 can be produced and / or formed by repeatedly guiding at least one yarn and / or thread through the outer material 3, especially through the outer material folding section 3A' and the second outer material section 3B.

[0145] The multifilament yarn can be based on corresponding single filaments.

[0146] The special seam design, particularly not only of the connecting seam 5 but also of the outer material closing seam 7 and / or the inner material closing seam 8, as can be provided within the scope of the present invention, can in particular avoid the use of adhesives for joining the respective components in the connection area or the formation of welds or the like. In particular, this avoids the disadvantages associated with the use of adhesives or welds, such as insufficient flexibility or elasticity and sometimes inadequate stability, for example due to material incompatibilities or the like.

[0147] Against this background, it is therefore particularly provided according to the invention that the outer material closing seam 7 and / or the inner material closing seam 8, in particular the same or different and / or independent of each other, is / are not designed as an adhesive seam (adhesive bond or adhesive bond seam) and / or have / have at least substantially no adhesive and / or are not formed by bonding.

[0304] The present invention is illustrated by the following exemplary embodiments, which, however, are not intended to limit the present invention in any way. EXAMPLES OF EXECUTION: General explanations

[0305] The following describes investigations into the protective function of various protective materials against pollutants, toxins, and chemical warfare agents. These investigations focus on protective material samples based on an air-permeable, multi-layered textile material, where the multi-layered textile material consists of an outer textile layer and an inner textile adsorption filter material. Further details on the examined protective material samples

[0306] Different protective material samples will be provided: 1. Reference materials R1 and R2 are provided, each in the form of a multilayer textile material without further stitching and therefore also without stitching according to the invention. Reference materials R1 and R2 thus represent textile surface materials as such, specifically in the sense of a single or individual section (i.e., a single cut piece or piece of material). The multilayer textile material of the respective reference materials R1 and R2 has a textile outer material in the form of a hydrophobic and oleophobic, air-permeable textile surface material. The outer material is identical for R1 and R2. The multilayer textile material of the respective reference materials R1 and R2 further comprises a textile adsorption filter (inner) material designed as an air-permeable laminate. The adsorption filter (inner) material of the first reference material R1 has a three-layer structure, consisting of a textile support layer, an adsorption layer based on activated carbon particles applied to it, and a cover / spacer / intermediate layer applied to the adsorption layer. The support layer is a knitted fabric made from a cotton / elastane blend. The adsorption layer uses adsorber particles in the form of spherical particulate activated carbon (spherical activated carbon particles), with the spherical activated carbon having an average particle diameter D. 50 The filter material has a thickness of 0.25 mm. A polyamide-based mesh fabric is used as the cover, spacer, or intermediate layer. The adsorption filter (inner) material of the first reference material R1 has a basis weight of approximately 370 g / m². 2 and a thickness of approximately 1.3 mm (see also Fig. 3-II). The adsorption filter (inner) material of the second reference material R2 corresponds to that of the first reference material R1, with the modification that a particle or aerosol filter layer is arranged between the adsorption layer and the cover / spacer / intermediate layer, specifically based on a specially designed nonwoven fabric. The adsorption filter (inner) material of the second reference material R2 has a basis weight of approximately 385 g / m². 2 and a thickness of approximately 1.5 mm (see also Fig. 3-III, however with an additional cover or spacer or intermediate layer on the side of the particle or aerosol filter layer facing away from the adsorption layer). For the reference materials R1 and R2, the outer material (top layer or outer fabric) is arranged or placed on the cover or spacer or intermediate layer of the adsorption filter (inner) material to form the respective multilayer textile material. 2. Based on the first reference material R1 or the second reference material R2, material samples according to the invention are provided, namely material samples E1a and E1b according to the invention based on the first reference material R1 and material samples E2a and E2b according to the invention based on the second reference material R2. (i) To produce the material E1a according to the invention, two sections (i.e., two cut pieces or material pieces of the first reference material R1; without a particle or aerosol filter layer) are joined together by sewing along their edges, based on the first reference material R1. Adjacent or overlapping sections are joined together in a connection area, particularly at the edges, by sewing or by means of a connecting seam. Furthermore, the sewing or formation of the connecting seam is carried out in such a way that, on the outside, especially on the outer side of the material sample facing exposure to chemical, biological or radioactive harmful or toxic substances, there is no penetration by the sewing or the connecting seam, or in such a way that there is no outer seam formed by the connecting seam, or in such a way that the connecting seam is covered on the outside by a first outer material section. The connection area is designed such that the first outer material section and the first adsorption filter (inner) material section are each folded inwards at their edges, while the second outer material section and the second adsorption filter (inner) material section have a free, unfolded, or unfolded end section at the connection area. Furthermore, the connection area has no seams or similar features. Overall, the structure of the connection area in the material E1a according to the invention corresponds to the present embodiment of the connecting seam as described in Fig. 1. situation shown. (ii) Furthermore, a material E1b according to the invention is provided, which corresponds to the material E1a according to the invention (based on the reference material R1; without particle or aerosol filter material) with the proviso that additional closing seams are present in the connection area, namely, on the one hand, an outer material closing seam (first closing seam) for further connecting the folded section of the first outer material section with the second outer material section (whereby there is likewise no external penetration or external seam) and, on the other hand, an inner material closing seam (second closing seam) for connecting the folded section of the first adsorption filter (inner) material section with the second adsorption filter (inner) material section. The structure of the connection area of ​​the material E1b according to the invention can be arranged accordingly in the schematic representation according to Fig. 2 can be taken. Overall, the structure of the connection area in the material E1b according to the invention corresponds to the present design of the connecting seam and closing seams as described in Fig. 2 situations shown. (iii) The material E2a according to the invention is obtained by edge-stitching two sections of the second reference material R2 (i.e., two cut pieces or material pieces of the second reference material R2; with a particle or aerosol filter layer). The design of the joining area with the special joining seam (and without closing seams) corresponds to that of the first material E1a according to the invention. In particular, the second material E2a according to the invention is also designed such that there is no external seam in the joining area. In this regard, reference can be made to the schematic representation according to Fig. 1 will be referred. Overall, the structure of the connection area in the material E2a according to the invention corresponds to the present embodiment of the connecting seam as described in Fig. 1. situation shown. (iv) Furthermore, the material E2b according to the invention corresponds to the material E1b according to the invention with the structure of the connection area described therein (i.e., with additional closing seams), wherein the fourth material E2b according to the invention is based on the second reference material R2 (i.e., with a particle or aerosol filter layer). Reference can be made to the schematic representation according to Fig. 2 are referred to. Overall, the structure of the connection area in the material E2b according to the invention corresponds to the present design of the connecting seam and closing seams as described in Fig. 2 situations shown. 3. In addition, further comparison materials V1 and V2 will be provided: A first comparison material V1 and a second comparison material V2 are provided, wherein the first comparison material V1 is based on sections or cut pieces of the multilayer textile material based on the first reference material R1, and wherein the second comparison material V2 is based on sections or cut pieces of the multilayer textile material of the second reference material R2. The design of the connection area corresponds to the third material E1b or the fourth material E2b according to the invention, such that one connecting seam and two closing seams are present in each case, with the proviso that the connecting seam completely penetrates the material or the respective sections or parts (i.e., a connecting seam penetrating all layers or material layers). With regard to the respective connecting seam of the comparison materials V1 and V2, the connecting seam in the connection area completely penetrates the unfolded first outer material section, the folded second outer material section, the unfolded second adsorption filter (inner) material section, and the folded first adsorption filter (inner) material section. The second comparison material V2 is designed analogously to the first comparison material V1, but with the proviso that corresponding sections or cut parts of the multilayer textile material are used based on the second reference material R2 (i.e. with particle or aerosol filter layer), as previously explained. Details of the investigations

[0307] The protective function against harmful or toxic substances (specifically mustard gas, HD) of all the aforementioned protective materials R1, R2, E1a, E1b, E2a, E2b, V1 and V2 is examined: The protective function against chemical warfare agents (mustard gas, HD) is determined based on the so-called standardized diffusion flow test with a drop applied to the surface ("laid drop diffusive flow test"). For this purpose, the respective materials described above are clamped in a test cell over a PE membrane simulating human skin. Drops of the chemical warfare agent (eight drops of mustard gas per material, each with a volume of 1 µl) are applied to defined areas of the materials under test using a cannula (specifically, in a central area on the outer material for reference materials R1 and R2, and in the connection area or in the area of ​​the seam on the unfolded section of the outer outer material).

[0308] The test conditions are as follows: relative humidity no more than 5% RH, temperature 23°C, mustard gas exposure for 24 hours, flow rate under the material 100 ml / min, flow rate above the material 0.5 m / s, flow rate through the material 0 cm / s. The airflow under the sample is drawn through a wash bottle. The cumulative breakthrough is measured by gas chromatography (GC / FPD) and expressed in µg / cm³. 2 specified per 24 hours. These tests simulate the diffusion of liquid warfare agent through the sample material without convection and simulate the surface contact of the protective clothing with the skin, the latter being simulated by the PE membranes.

[0309] The diffusion flow test thus simulates the diffusion of liquid warfare agent through the underlying protective material without convection and simulates the flat contact of the protective clothing with the skin, the latter being simulated by the PE membrane.

[0310] Smaller values ​​for cumulative breakthrough in µg / cm³ mean lower values. 2 Improved protection and barrier performance against harmful substances and toxins, especially chemical warfare agents, is achieved every 24 hours. The minimum specification is a maximum of 4 µg / cm². 2 per 24 hours. Investigation results:

[0311] Based on the previously described Laid Drop Diffusive Flow Test, the following values ​​can be determined for the materials under investigation, whereby these are cumulative breakthrough values. Material R1* R2* E1a E1b E2a E2b V1** V2** cumulative breakthrough [µg / cm³] 2 per24 h] 0,07 0,06 0,3 0,2 0,2 0,1 3,1 2,9 * Referenzmaterial ** Vergleichsmaterial

[0312] The investigations show the excellent protective properties of the protective material samples E1a, E2a, E1b and E2b according to the invention, with the inventive concept of the special design or sewing of the connection area of ​​corresponding sections of the respective multilayer textile material used.

[0313] The materials according to the invention exhibit a protective performance comparable to, or of the same order of magnitude as, the respective reference materials R1 and R2, as a result of the seam construction according to the invention.

[0314] The protective performance can be further increased by using additional sealing seams, as implemented in materials E1b and E2b. Thus, material E2a with additional sealing seams, but without an additional particle or aerosol filter, achieves the same level of protection as material E1a without additional sealing seams, but with an additional particle or aerosol filter.

[0315] In contrast, the protective properties determined for the comparison materials V1 and V2 are significantly lower (although they still meet the specification overall), particularly due to the continuous or penetrating seam, which penetrates all material layers and is therefore permeable to the chemical agent.

[0316] Within the scope of the present invention, it has thus surprisingly been possible to provide a high level of protection against the effects of harmful or toxic substances through the targeted and purposeful special design of the connection area, in particular with the special seam construction according to the invention, wherein the connection area as a whole also has excellent mechanical properties and exhibits high stability in this respect.

[0317] The materials E1a, E1b, E2a, and E2b according to the invention are further subjected to tensile and elongation stress with simultaneous bending stress, each in 50 repetition cycles. The previously described test is then carried out on the claimed materials. Essentially comparable results are obtained, with materials E1b and E2b retaining improved properties due to the additional closure seams (cumulative breakthrough values ​​in µg / cm²). 2per 24 h: E1a: 0.4; E1b: 0.2; E2a: 0.3; E2b: 0.2).

[0318] In summary, the above explanations demonstrate the very good protective properties of the materials according to the invention.
