Description

[0001] ABC protective clothing with improved protection in the seam area

[0002] The present invention relates to the technical field of protective clothing with a protective function against chemical and / or biological and / or radioactive pollutants or toxic substances (such as hazardous substances, warfare agents or the like), as it can be used in particular in the military and civilian sectors.

[0003] In particular, the present invention specifically relates to NBC protective clothing or CBRN protective clothing (where ABC stands for atomic, biological, and chemical, and CBRN stands for chemical, biological, radioactive, and nuclear; the terms ABC and CBRN are used synonymously within the scope of the present invention). In this context, the present invention also relates to the technical field of corresponding NBC or CBRN protective clothing, such as can be used in particular for military purposes or for civilian purposes, for example in the field of hazard prevention, firefighting, disaster control, or the like.

[0004] Against this background, the present invention relates in particular to protective clothing with a protective function against chemical or 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 warfare agents, wherein the protective clothing according to the invention has a first layer in the form of a multi-layer, textile, air-permeable adsorption filter material and a second layer in the form of a textile, air-permeable cover material on the one hand and, in addition, a third layer in the form of a non-textile and air-impermeable sheet material (which is also, in particular, water (vapor)-impermeable and, in particular, single-layered) on the other hand, wherein the layers are connected to one another in a connecting region with a common seam (layer connecting seam).are sewn together, wherein in addition, a specially designed and specially arranged additional textile adsorption filter material, which is multi-layered and air-permeable, is present or used, wherein the additional textile adsorption filter material is connected or sewn to the aforementioned layers by means of the same seam (namely the layer connecting seam). Furthermore, the present invention also relates to a related protective material as such, which equally has a protective function against chemical, biological, or radioactive pollutants and toxins. Furthermore, the present invention also relates to protective equipment or protective articles as well as filters and filter materials which are produced using the protective material according to the invention or which comprise such a protective material according to the invention.In this context, the present invention also relates to the use of the protective material according to the invention for the production of protective equipment or protective articles as well as for the production of filters and filter materials.

[0005] The present invention further relates to a method for sealing against chemical and / or biological and / or radioactive pollutants or toxins a connecting region of textile layers on the one hand and a non-textile (sealing) layer on the other hand, a protective clothing or a protective material using an additional adsorption filter material.

[0006] Furthermore, the present invention also relates to the use of an additional adsorption filter material in the connection area of ​​textile layers on the one hand and a non-textile (sealing) layer on the other hand, a protective clothing or a protective material for sealing the connection of the textile layers overlapping in the connection area on the one hand and the non-textile layer on the other hand.

[0007] Furthermore, the present invention also relates to the use of an additional adsorption filter material for sealingly connecting a transition region between textile layers or materials on the one hand and a non-textile layer or material on the other hand.

[0008] Harmful or toxic substances generally pose a high level of danger and can have a detrimental effect on the health of anyone who comes into contact with them. Any exposure to or contact with them, for example through contact with skin or mucous membranes, inhalation, ingestion, or the like, must therefore be avoided or at least minimized. This is particularly important given that the health impairments and toxic potential of such substances can sometimes be considerable, and that contact with or ingestion of even small amounts of such substances can lead to long-term health problems or even death in those affected. In this context, it should also be noted that toxic or harmful substances can exist in numerous chemical and physical forms, for example as gases, liquids, or solids, and in the form of finely divided or finely particulate aerosols.from pollutant particles or the like present in the (ambient) air.

[0009] Not least against this background, there is a great need or necessity to provide people who are at risk of coming into contact with toxic or harmful substances, such as soldiers, firefighters, police officers, members of special or special units or the like, with appropriate protective clothing with ABC or CBRN protection function, in order to prevent the absorption of corresponding toxic or harmful substances when deployed in a contaminated or polluted environment by wearing the protective clothing.

[0010] Especially for groups of people such as soldiers, firefighters, police officers, members of special units, or the like, who are at increased risk of coming into contact with toxic or harmful substances, it is particularly advisable and necessary to ensure appropriate protection against these toxic or harmful substances, including by wearing respiratory masks (ABC respiratory masks or CBRN protective masks). Furthermore, toxic or harmful substances can often be absorbed or absorbed through the skin in addition to the respiratory tract, which represents a further high risk potential. In this respect, it is often necessary for these people to wear appropriate protective clothing (ABC or CBRN protective clothing) in addition to a respiratory mask in order to prevent contact of the toxic or harmful substances with the skin or body.In this context, such protective clothing, which may be in the form of protective suits, protective jackets or the like, often also includes a corresponding headgear or hood, for example in the form of a hood or a balaclava.

[0011] In this context, the general purpose of ABC or CBRN protective clothing is to provide the wearer or user with optimal or additional protection against harmful or toxic substances, particularly insofar as the wearer or user of such protective clothing is, on the one hand, protected as best as possible and, on the other hand, can continue to carry out their operational duties or activities as unhindered as possible. Thus, in addition to providing appropriate protection against toxic or warfare agents, the wearing comfort provided by the protective clothing also plays a major role, both with regard to a good fit and the provision of moisture or thermoregulatory properties when the protective clothing is worn. With regard to the provision of this type of protective clothing, a major challenge is to provide the most holistic and / or versatile orTo provide comprehensive and reliable protection, ensuring protection against a wide variety of different toxins and harmful substances, or those present in various (physicochemical) forms. The often conflicting properties of providing a high level of protection on the one hand and a high level of comfort on the other should be equally fulfilled in one and the same material.

[0012] With regard to protective clothing, it is also necessary to ensure the longest-lasting and most versatile protection possible against toxins and harmful substances, whereby the protective function is guaranteed even in the event of high local pollutant or toxic substance concentrations (e.g. in the event that a drop of a pollutant or toxic substance comes into direct contact with the protective clothing) and thus in the event of high local pollutant or toxic substance concentrations. The protective function must also be guaranteed for long periods of time and under adverse operating conditions, and this must also apply to particularly critical sections or areas of the protective clothing, such as seams and end or transition areas, for example for connecting individual surface sections or layers of the components used, as well as in the area of ​​transition or opening areas (passage areas) of the protective clothing, for example head orNeck openings, field of vision openings, abdominal or pelvic openings, arm or hand openings, leg or foot openings or the like. The same applies to transition or connecting areas between protective clothing worn together or at the same time, such as between a jacket and trousers or between a sleeve of a jacket and a glove or a protective system (such as the transition or connecting area or interface between a headgear or hood and a breathing mask or the like). Such locations or sections and transition areas are particularly problematic with regard to providing an efficient and permanent seal against the ingress of harmful or toxic substances. In order to improve wearer comfort while at the same time providing a high level of protection against harmful or toxic substances.In principle, air-permeable, permeable protective clothing systems are known in the prior art for the protection against harmful or toxic substances. These systems can be equipped with an adsorption filter layer, particularly to ensure protection against harmful or toxic substances. Due to the increased exchange of air and water or water vapor, such protective systems offer improved wearer comfort while generally providing good protection against toxic or harmful substances. With regard to such protective clothing, it is sometimes also the case that the adsorption material used, if any, is arranged on the side of the material facing the wearer or user when worn, so that any toxic or harmful substances that have previously penetrated the material can be absorbed by the adsorption material.

[0013] The aforementioned air-permeable protective clothing is often manufactured using different, particularly layered or arranged textile materials for function- or wear-specific training, with the corresponding layers or sections being permanently connected to one another by seams or seam connections. The seam connections used for this purpose generally run through the surface of the material, with the underlying protective material in its thickness or the layers used for this purpose often being completely encompassed or penetrated by a seam connection. However, in the case of high concentrations or large quantities of, in particular, liquid pollutants or toxic substances, such seam connections represent weak points with regard to the possible entry of these pollutants or toxic substances, since seams running through the cross-section of the material in particular can act as breakthrough or penetration points.Represent or form entry openings for harmful or toxic substances coming into contact with the protective clothing from the outside, for example in the form of drops or aerosols or the like, especially since the yarns or threads used to form the seam can conduct harmful or toxic substances through the material along the yarn or thread path. On this basis, particularly in the case of high (local) hazardous substance contamination, local breakthroughs of harmful or toxic substances can occur, which is associated with a corresponding risk to the wearer or user of the protective clothing, especially since the adsorption materials sometimes used can quickly or locally be overloaded at the underlying (seam) breakthrough points and the harmful or toxic substances that have penetrated or penetrated can spread on the inside and thus on the side of the protective clothing facing the wearer. In this context, the prior art can in principle provide for such seams orSeam joints are sealed to a certain extent with so-called seam sealing tapes. For this purpose, air- and water- or vapor-impermeable materials, such as polymer or plastic tapes, are generally used. These tapes are generally flat and are applied, for example, along the seam line to externally cover the seam joint. Adhesives are generally used for this purpose.

[0014] In this way, a certain degree of sealing can be provided against harmful or toxic substances acting on the material from the outside. However, such sealing concepts are inadequate because, for example, the adhesive bond can loosen, particularly when the material is subjected to mechanical or thermal stress, as often occurs during application or use, so that the previously covered seam is exposed again. In addition, harmful or toxic substances can bead up or flow off the seam sealing tape and be transferred in larger quantities to the adjacent (textile) material, thus overloading the latter. There are also production-related disadvantages because the air and water vapor impermeable seam sealing tape has to be applied subsequently, which requires separate production processes or steps. In addition, the stability and / orThe function of the seal and the protective material equipped with it may be reduced due to material incompatibilities or the like.

[0015] Furthermore, wearing comfort can be reduced because the seam sealing tapes used are often thick and inflexible, although these properties are further enhanced by the additional use of an adhesive. The washing and regeneration resistance of such systems is also inadequate because the associated high material stress can lead to the seam sealing tape becoming detached. In particular, it is difficult to carry out a visual inventory or wear inspection, particularly with regard to detecting minor detachments or similar of the seam sealing tape. Furthermore, air- or water-impermeable seam sealing tapes with the associated adhesive are not suitable for sealing orCovering seams used to connect (surface) sections made of different materials, since material incompatibilities can also arise here, particularly with regard to the adhesive used. Furthermore, the prior art uses textile reinforcement layers to connect 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 as the outer layer, based on a plurality of inserts or sections that are connected to one another by sewing, and with a textile layer as the filtering material layer.The protective clothing has a textile layer called a reinforcement layer in the area of ​​a joint. This layer is both hydrophilic and oleophilic and is connected to two inserts or sections of the outer textile layer by the same seam. Due to the properties of the reinforcement layer, harmful or toxic substances penetrating the material or through the seam are specifically absorbed by the absorbent properties or high affinity of the reinforcement layer and passed on to the filtering material layer.

[0016] Thus, a concept is pursued whereby harmful or toxic substances that impact the protective clothing are specifically absorbed and transferred to the filtering material layer or to the adjacent material structures. However, this can be accompanied by rapid depletion or local overload of the adjacent materials, especially the filtering material layer, so that optimal protection is not always achieved. In particular, the material used as the reinforcement layer has no or at least insufficient adsorptive properties.

[0017] A particularly critical structure with regard to an unwanted breakthrough or penetration of harmful or toxic substances is the area of ​​openings in protective clothing for the reception or passage of body parts of a wearer or user. The same applies to the transition area or contact area between different elements of protective clothing, for example a jacket on the one hand and trousers on the other, or a jacket or a sleeve of a jacket on the one hand and a glove on the other. The transition area of ​​protective clothing for the sealing accommodation of other protective items or equipment, such as a respiratory mask in the field of vision, in particular the mask body of a respiratory mask, is also critical with regard to the penetration of harmful or toxic substances.In the aforementioned areas, non-textile, air- and water-impermeable surface materials are often used in sections, for example those based on polymers or plastics. The corresponding air- and water-impermeable or non-textile layers or sections are connected to the other textile layers or components of the protective clothing via seams. In the underlying connection area between textile components or layers on the one hand and non-textile, air-impermeable components or layers on the other, the risk of harmful or toxic substances entering or breaking through and / or passing through is particularly high, especially since the non-textile and air-impermeable layer itself is not designed to absorb harmful or toxic substances. Since harmful or toxic substances can adhere to the surface of the non-textile and air-impermeable component or layer.If the harmful or toxic substances are present in larger quantities or concentrations on the adjacent textile surface materials, particularly on the side facing the environment, there is an increased risk that the harmful or toxic substances can penetrate the material or protective clothing through the seam as a weak point and penetrate it.

[0018] Even an oleophobic and / or hydrophobic treatment, which is generally provided for in the prior art, in particular of the outer layer of textile sheet materials forming the (main) surfaces of protective clothing, cannot sufficiently counteract the penetration of harmful or toxic substances, in particular in the area of ​​seam connections, and in particular with regard to the transition area between textile sheet material on the one hand and air- and water-impermeable sheet materials on the other.

[0019] In particular, hydrophobic or oleophobic treatment of textile surface materials can result in harmful or toxic substances beading up or flowing off the surface when they come into contact with the protective clothing and also affecting the corresponding seam areas, accumulating or agglomerating there, in addition to the harmful or toxic substances coming into contact with the non-textile or air- and water-impermeable sections or materials. This can lead to local overloading in the area of ​​the corresponding seam connections between these materials and to a risk of harmful or toxic substances penetrating or seeping through these areas. In general, the seams or seam connections used to connect the respective surface materials in protective clothing represent weak points or locations with regard to the penetration or seeping through of harmful or toxic substances that come into contact with the protective clothing.Toxic substances represent a potential source of danger, as the surface materials forming the protective clothing are pierced or penetrated in the area of ​​their connections by the thread or yarn forming the seam, thereby weakening the structure. Harmful or toxic substances that impact or act on the protective clothing from the outside can be conducted or transported inward along the thread or yarn through the material or the associated material arrangement, which is generally undesirable, especially since any existing adsorption layer in the area of ​​the penetration point can also be locally overloaded.

[0020] Critical areas with regard to the penetration of harmful or toxic substances are particularly found in openings for the sealed insertion or passage of body parts (e.g., arm, leg, or foot openings) or for the sealed insertion of additional protective devices, such as respiratory masks (e.g., in conjunction with a field of vision opening), since these are penetrated or perforated by the thread or yarn forming the seam when sewn to the other surface materials of a protective clothing, creating corresponding weak points. As a result, harmful or toxic substances acting on the material can penetrate through the opening or along the thread or yarn into the protective clothing with comparatively little resistance and reach the wearer and / or user of the protective clothing.

[0021] This entails a corresponding risk of excessive exposure or exposure of a person in the danger zone to the pollutants or toxic substances in question.

[0022] Thus, textile seams for fastening non-textile and air- and water-impermeable surface materials do indeed ensure a certain degree of mechanical stability and flexibility. However, with regard to the unwanted penetration of harmful or toxic substances, corresponding breakthroughs or weak points, i.e. areas of weakness, are created. In this respect, the corresponding seam connections represent a weak point or impairment with regard to the protective properties against harmful or toxic substances acting on or impinging on the protective clothing. Overall, in order to provide effective sealing of the special transition area between textile components or layers on the one hand and non-textile and air- and water-impermeable components or layers on the other, the seam connection present there against harmful orToxic substances place particularly high demands on the product, taking into account the different material properties of the components or layers used on the one hand and the surface-specific contact of harmful or toxic substances, particularly in the seam area, on the other.

[0023] Against this background, there is therefore a great need in the state of the art to provide technical solutions for the effective sealing of the critical transition or connection area of ​​protective clothing from textile and in particular air-permeable components or layers (in particular in the form of textile sheet materials) on the one hand and non-textile, air-impermeable components or layers (in particular in the form of non-textile sheet materials) on the other hand.

[0024] In this context, there is also a great need, in particular, to effectively protect the corresponding transition area or opening area in protective clothing, in which such a material combination or connection based on textile and in particular air-permeable surface materials on the one hand and non-textile and air-impermeable surface materials on the other hand, also in the seam connection area against the entry or breakthrough or penetration of harmful or toxic substances hitting the material.

[0025] In particular, there is also a great need in the state of the art to effectively protect the opening area of ​​protective clothing (for example in the form of a hood or hooded jacket or a head cap or the like) in the edge area of ​​the field of vision against the entry of harmful or toxic substances, also with regard to the specific transition or sealing area with a respiratory mask or a mask body of a relevant respiratory mask.

[0026] In this regard, the concepts available in the prior art often do not provide a satisfactory solution to the underlying problem, as previously mentioned. Against this background, the present invention is based on the object of providing an efficient technical solution for providing effective sealing of a seam connection in the transition or connection area of ​​the sheet materials or layers of the components used in protective clothing, whereby the previously described disadvantages of the prior art are to be at least largely avoided or at least mitigated.

[0027] In this context, a particular object of the present invention is to provide protective clothing which has an ABC protection function (CBRN protection function) and which can preferably be used or employed for the civilian and / or military sector and which has improved sealing properties against harmful or toxic substances in the transition or connection area of ​​the surface materials or layers which specifically form the protective clothing, wherein the transition or connection area is to be sealed against harmful or toxic substances, so that the entry of harmful or toxic substances in the transition or connection area with a corresponding contact of the wearer or user of such protective clothing is to be prevented.

[0028] Furthermore, a further object of the present invention is to protect the transition or connection area of ​​a corresponding protective clothing, in which the respective surface materials or layers of the components used meet and are sewn or permanently connected by means of seams to form the protective clothing, in an efficient manner against the entry or penetration of harmful or toxic substances acting on or impacting the protective clothing or the transition or connection area, wherein in particular the entry or passage of such harmful or toxic substances through the seam or seam connection as such or the relevant seam area / section is to be prevented or at least reduced.

[0029] In this context, the area of ​​protective clothing that serves to sealably accommodate or pass through a body section or to sealably accommodate or connect to other protective equipment, such as a respirator, should also be protected against the ingress or penetration of harmful or toxic substances, particularly with regard to the connection area of ​​the underlying material components or surface materials of the protective clothing. In this regard, too, the ingress or penetration and / or breakthrough of harmful or toxic substances in the seams or seam connections / stitching used to connect the components should be prevented.

[0030] Furthermore, against this background, one object of the present invention is to efficiently protect the connecting area between textile, air-permeable sheet materials on the one hand and non-textile, air-impermeable sheet materials on the other hand from the ingress of harmful or toxic substances. This applies in particular against the background of a sealing function when protective clothing is worn or used to seal body parts of a wearer or user and / or other protective equipment, such as a respirator. The focus here is on the seams or stitching used in this regard, as they are used to connect the respective sheet materials.

[0031] Furthermore, a further object of the present invention is to provide a suitable seal for corresponding connecting areas of textile, air-permeable sheet materials on the one hand and non-textile, air-impermeable sheet materials on the other hand of ABC protective clothing or NBRC protective clothing against harmful or toxic substances that act externally on the protective clothing or the connecting area when the protective clothing is worn or in use. In this case, a high level of protection against the entry or penetration of the harmful or toxic substances in question should be ensured even in the presence of high quantities or concentrations of toxic substances or pollutants in the area where the sheet materials are connected.

[0032] In addition, a further object of the present invention is to provide corresponding sealing properties against harmful or toxic substances in the connection area in question, wherein the measures in this regard should not negatively affect the wearing comfort or the functional properties - for example with regard to the seal against other protective equipment, such as a respiratory mask. In addition, it should also be ensured overall that the underlying measures lead to a permanent and mechanically stable seal. In particular, a connection area underlying the clothing should be able to withstand strong mechanical stress during use or application while at the same time being highly flexible. In particular, a further object of the present invention is to provide a corresponding concept for preventing the entry or entry of harmful or toxic substances.The aim is to provide a seal to prevent the penetration of harmful or toxic substances into such a connecting area between textile, air-permeable surface materials on the one hand and non-textile, air-impermeable surface materials on the other, as is used or exists specifically for headgear or head hoods, for example in the form of a hood or balaclava, for the sealing transition or for the sealing reception of additional protective equipment in the form of a respiratory mask, in particular an ABC respiratory mask. In addition to preventing the entry or passage of harmful or toxic substances in the connecting area itself, a good seal against the respiratory mask should also be provided, while at the same time being highly adaptable, for example with regard to different types or designs of respiratory masks.

[0033] Furthermore, a further object of the present invention is to provide a general technical concept for sealing the underlying connection area or a seam connection between textile air-permeable sheet materials on the one hand and non-textile air-impermeable sheet materials on the other hand, which can be used for a variety of different designs of the underlying protective clothing, for example with regard to different transition or opening areas for receiving or passing through different body sections or for receiving different protective equipment or the like.

[0034] The measures used to solve the underlying problem according to the present invention should be optimized in terms of process and conception and be able to be implemented universally and should also enable the production of corresponding protective clothing on an industrial scale.

[0035] To achieve the above-described problem, the present invention thus proposes—according to a first aspect of the present invention—the inventive protective clothing with a protective function against chemical or biological or radioactive pollutants and / or poisons (warfare agents), in particular NBC protective clothing, preferably for civil or military purposes, according to patent claim 1; further advantageous developments and refinements of this aspect of the invention are the subject of the corresponding subsidiary claims and dependent claims relating to the inventive protective clothing.

[0045] In particular, with regard to the features characterizing the invention, any combination of these features is deemed to be disclosed, whereby embodiments of the various features with the same preference are preferred in their combination (e.g., amounts or ranges of amounts of the relevant ingredients with 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.

[0046] With this in mind, the present invention is described and explained in more detail below, also with reference to drawings or figure representations showing preferred embodiments or exemplary embodiments.

[0047] The subject matter of the present invention - according to a first aspect of the present invention - is thus protective clothing with a protective function against chemical and / or biological and / or radioactive pollutants and / or poisons (warfare agents) ("ABC or CBRN protective function"), in particular ABC protective clothing ("CBRN protective clothing"), preferably for civil or military purposes, wherein the protective clothing

[0048] (a) a first, in particular flat and / or two-dimensional, layer in the form of a multi-layer, in particular at least two-layer, textile air-permeable adsorption filter material ("inner layer", "inner fabric"), in particular for the adsorption of chemical and / or biological and / or radioactive pollutants and / or toxins, wherein the adsorption filter material has an adsorption layer and a textile carrier layer ("adsorption layer carrier"),

[0049] (b) a second, in particular flat and / or two-dimensional, layer in the form of a textile, air-permeable covering material ("top layer", "outer fabric") and (c) a third, in particular flat and / or two-dimensional, layer in the form of a non-textile, in particular polymer-based and / or plastic-based, air-impermeable sheet material, wherein the layers (i.e. the first layer, the second layer and the third layer) are arranged and / or positioned overlapping one another in a connecting region and are connected, in particular sewn, to one another in the connecting region with a common seam forming a seam region ("layer connecting seam"), wherein at least in the seam region an additional multi-layer, in particular at least two-layer, textile, air-permeable, preferably strip-shaped orband-shaped adsorption filter material, in particular for adsorbing chemical and / or biological and / or radioactive pollutants and / or toxins occurring in the seam area and / or in particular for preventing breakthroughs of chemical and / or biological and / or radioactive pollutants and / or toxins in the seam area (or in the connection area), is arranged and / or provided and / or is present, wherein the additional adsorption filter material is connected, in particular sewn, to the layers (ie to the first layer, the second layer and the third layer) by means of the seam (the same seam).

[0050] A central idea of ​​the present invention is therefore to be seen in particular in the fact that, for the special area of ​​sewing or connecting the layers forming the protective clothing according to the invention, on the one hand, based on the first and second layers, each of which is in particular flat or two-dimensional in the form of respective textile, air-permeable (textile) materials, and on the other hand, the third layer, which is in the form of a non-textile and air-impermeable sheet material and is used in particular as a transition area for receiving or passing through a body section or for sealingly receiving or connecting further protective equipment, additionally a textile adsorption filter material is provided, which is multi-layered and air-permeable and preferably in the form of a strip and / or band.

[0051] In this context, the invention specifically provides for the additional adsorption filter material to be connected by means of the same seam that connects the aforementioned layers, namely the first, second, and third layers, in the seam or connection area. According to the invention, the first layer ("inner layer", "inner fabric"), the second layer ("top layer", "outer fabric"), and the third non-textile, air-impermeable layer in the form of the particularly polymer-based or plastic-based sheet material and the additional adsorption filter material are connected in the seam or connection area.

[0052] According to the present invention, the first, second, and third layers forming the protective clothing, on the one hand, and the additional adsorption filter material, on the other hand, are connected to one another by one and the same seam. Within the scope of the present invention, this is particularly the case that the additional adsorption filter material is, on the one hand, itself permeable to air and, on the other hand, is preferably strip-shaped or band-shaped, so that on this basis, the wearing comfort of the protective clothing according to the invention, while simultaneously providing a high level of protection against harmful or toxic substances, is not negatively affected, even in the seam area connecting the first, second, and third layers.

[0053] The applicant has discovered, quite surprisingly, that the targeted and purposeful use of a special adsorption filter material, namely in the form of a multi-layered, in particular at least two-layered, textile, air-permeable, preferably strip- or band-shaped, adsorption filter material as an additional layer in a seam area with an overlapping arrangement of the additional layers, leads to a significantly improved protective function against harmful or toxic substances. The overlap takes the form of a first layer, which is designed as a textile, air-permeable adsorption filter material ("inner layer", "inner fabric"), a second layer in the form of a textile, air-permeable covering material ("top layer", "outer fabric"), and a third layer in the form of a non-textile, in particular polymer-based or plastic-based, air-impermeable sheet material.The additional adsorption filter material arranged in the seam area is particularly strip-shaped or band-shaped and is connected to the aforementioned first, second, and third layers by the same seam. Harmful or toxic substances are effectively prevented from penetrating or passing through the protective clothing.

[0054] Within the scope of the present invention, a technical solution is therefore provided overall by means of which the transition area, which is particularly sensitive to the penetration of harmful or toxic substances, is effectively protected against harmful or toxic substances acting on the protective clothing in this area by means of a seam connection between air-permeable materials on the one hand and air-impermeable materials on the other hand in the form of the aforementioned first, second and third layers, thereby resulting in less stress or greater protection for a wearer of such protective clothing.

[0055] The present invention particularly aims to ensure that the additional adsorption filter material, particularly in the form of an additional strip or band, further protects the seam in question, which connects the first, second, and third layers of the protective clothing in the transition or seam area, against the penetration of harmful or toxic substances. This seam, which represents a particularly vulnerable point of penetration for harmful or toxic substances – particularly due to the phenomenon of "beading" or "agglomeration" of harmful or toxic substances hitting the protective clothing on the air-impermeable, non-textile third layer and the second (cover) layer, and the increased concentration or longer residence time of the harmful or toxic substances in the area of ​​the connecting seam – is secured with appropriate resistance by the measure according to the invention.

[0056] The additional adsorption filter material absorbs any harmful or toxic substances that may penetrate the area of ​​or through the seam, preventing them from penetrating further into the protective clothing or from penetrating it. In a corresponding manner, the first layer or inner layer in the form of the textile, air-permeable adsorption filter material is sustainably relieved of stress in the local seam or connection area, so that on this basis, too, the protective clothing according to the invention provides an overall high level of protection, since the inventive design prevents or suppresses (local) overloading of the first layer in the form of the adsorption filter material or the inner layer.

[0057] This is a key difference to the aforementioned prior art, in particular in the form of WO 2019 / 129656 A1 and EP 3 731 939 A1, according to which, within the scope of the present invention, no harmful substances are diverted to subsequent layers, which would otherwise be overloaded or concentrated in the subsequent layers, but rather any harmful or toxic substances penetrating through the seam are absorbed or rendered harmless by the additional layer used according to the invention due to its special adsorptive properties. This results in a further optimization of the protective effect provided in this regard within the scope of the present invention. By using a seam to join or sew the first, second orThe third layer and the additional adsorption material in the connection area ensure a mechanically resilient and permanent connection between the individual components, while simultaneously providing a high level of protection against the penetration of harmful or toxic substances. Using a common or identical seam to connect the aforementioned components also minimizes the number of weak points with regard to the potential ingress of harmful or toxic substances, as only a limited number of threads or yarns pass through the layers of the protective material, namely based on a single common seam. In other words, the third non-textile, polymer, or plastic-based layer is not excessively penetrated or "perforated," so to speak, by the thread or yarn guide.

[0058] A further advantage of the present invention is that, due to the targeted and purposeful use and arrangement of an additional, particularly strip- or band-shaped, adsorption filter material in the connection area, the use of (additional) sealing tapes, for example, rubber-based ones, can be avoided. In particular, the use of adhesives for connecting the underlying layers or components or for attaching sealing tapes can also be avoided.

[0059] In contrast, within the scope of the present invention, a high durability of the connection is also ensured, both with regard to the provision of a protective function against harmful or toxic substances and from a mechanical point of view with the high load-bearing capacity of the underlying (layer) connection.

[0060] In particular, within the scope of the present invention, undesirable delamination, such as can occur particularly with sealing tapes or the like applied by means of an adhesive bond, is avoided. Furthermore, due to the layers or components used and the special connection based on a common seam, the underlying connection area of ​​the protective clothing according to the invention exhibits high flexibility or elasticity, which benefits wearer comfort and also enables good adaptability to corresponding body parts of the wearer or to other protective items, such as respiratory masks. Accordingly, this excellent adaptability also provides further improved protection against harmful or toxic substances.

[0061] Due to the high mechanical stability, the protective clothing according to the invention can also be subjected to appropriate regeneration treatments (e.g. washing treatments) without the protective function or the mechanical stability of the underlying compound being negatively affected in the long term.

[0062] Furthermore, the present invention is associated with assembly and production-specific advantages, since the additional adsorption material can be directly incorporated or sewn during the production of the connection between the underlying layers, based on a common seam connection. This also eliminates the need for subsequent fixing, thereby reducing production steps. Furthermore, the invention can provide for the additional adsorption material to be made essentially of the same material as the first layer, so that, for example, corresponding cutting or assembly remnants of the material of the first layer can also be used for the additional adsorption material, which is particularly strip-shaped. This is associated with corresponding material utilization and thus with improved process economy.

[0063] The term "seam" used in the context of the present invention is to be understood in particular as a connection of the underlying layers or materials by sewing. For the seam, at least one yarn or thread is generally used, which is repeatedly passed through the sewing material in the form of the respective layers and the additional adsorption filter material, whereby the yarn or thread is connected or intertwined with the sewing material or the respective layers and the additional adsorption filter material. Thus, in the context of the seam connecting the first, second, or third layer and the additional adsorption filter material ("layer connection seam"), it is in particular a yarn- or thread-based seam. Accordingly, the seam in question is not a threadless connection or an adhesive seam or welded seam.

[0064] The use or formation of a corresponding seam ("layer connecting seam") for the joint connection of the first, second and third layers as well as the additional adsorption filter material is accompanied by a high level of stability or resilience and flexibility, so that a connection of the respective layers as well as the additional adsorption filter material that can withstand high force or mechanical loads while simultaneously providing a high level of protection against harmful or toxic substances is provided within the scope of the present invention.

[0065] The term "seam region," as used in the context of the present invention, is to be understood in this context in particular as representing a section or region of the connecting region with the overlapping arrangement or positioning of the layers, which is formed by the formed common seam with the corresponding seam-like engagement or connection of the first, second, and third layers as well as the additional adsorption filter material. The seam region thus refers in particular to the region of the connecting region in which the underlying layers and the additional adsorption filter material are connected or engaged by the common seam.

[0066] In this context, the terms "yarn" and "thread" are used synonymously within the scope of the present invention, with the aforementioned terms generally representing a collective term for all linear textile structures. In this context, a yarn or thread can comprise one or more fibers or filaments.

[0067] The term "connecting region" as used in the context of the present invention represents in particular the transition region between textile layers, in particular the first layer and the second layer of the protective clothing according to the invention, on the one hand, and a non-textile and in particular air-impermeable layer, in particular the third layer of the protective clothing according to the invention, on the other hand, i.e. in particular the region of the fixed or permanent connection of the layers in question. The connecting region is located or present in particular in the region of openings for the sealing reception or passage of body parts of a wearer or user or for the sealing reception or sealing contact with further protective equipment, such as a respiratory mask. Thus, the connecting region also defines a transition from the protective clothing to body parts of a wearer or user (i.e. in the wearing or(condition of use) or with respect to other protective items, such as a respirator. In particular, the connecting area within a headgear can define a field of vision or a field of vision opening for, in particular, sealingly accommodating a respirator.

[0068] The term "sealing" or "sealing", as used in the invention with regard to the protective clothing and the underlying connection area, is to be understood very broadly within the scope of the present invention and relates in particular to the prevention or at least the lasting reduction of the entry or penetration or permeation of gases, vapors, aerosols or liquids, in particular of toxic or harmful substances, i.e. hazardous substances, warfare agents or the like.

[0069] Sealing is to be understood in particular with reference to penetration through the protective clothing or the corresponding connecting area, in particular the seam area present in the connecting area in particular, and thus in particular to a transition area between textile components or layers on the one hand and a non-textile component or layer on the other, e.g., an opening area for receiving or connecting to additional protective equipment, such as a respiratory mask, or body parts of a wearer or user. Furthermore, the term "sealing" or "sealing" can also refer, for example, to the connection to or receiving of protective equipment, such as a respiratory mask, or body parts of a wearer or user, in particular through or by means of the non-textile third (sealing) layer.

[0083] The figures according to Fig. 1 to Fig. 9A and 9B particularly illustrate the first aspect of the present invention, according to which, according to the invention, a protective clothing 1 with a protective function against chemical and / or biological and / or radioactive pollutants and / or poisons (warfare agents) ("ABC or CBRN protective function"), in particular ABC protective clothing ("CBRN protective clothing"), preferably for civil or military purposes, is proposed, wherein the protective clothing 1

[0084] (a) a first, in particular flat and / or two-dimensional, layer 2 in the form of a multi-layer, in particular at least two-layer, textile air-permeable adsorption filter material ("inner layer", "inner fabric", "inner lining"), in particular for adsorbing chemical and / or biological and / or radioactive pollutants and / or toxins, wherein the adsorption filter material has an adsorption layer 2a and a textile carrier layer 2b ("adsorption layer carrier"),

[0085] (b) a second, in particular flat and / or two-dimensional, layer 3 in the form of a textile air-permeable covering material ("top layer", "outer fabric") and

[0086] (c) a third, in particular flat and / or two-dimensional, layer 4 in the form of a non-textile, in particular polymer-based and / or plastic-based, air-impermeable sheet material, wherein the layers 2, 3, 4 are arranged and / or positioned overlapping one another in a connecting region 5 and are connected, in particular sewn, to one another in the connecting region 5 with a common seam 7 forming a seam region 6 ("layer connecting seam"), wherein at least in the seam region 6 an additional multi-layer, in particular at least two-layer, textile air-permeable, preferably strip-shaped and / or band-shaped, adsorption filter material 8,in particular for adsorbing chemical and / or biological and / or radioactive pollutants and / or toxins occurring in the seam area 6 and / or in particular for preventing breakthroughs of chemical and / or biological and / or radioactive pollutants and / or toxins in the seam area 6 (or in the connecting area 5), ​​wherein the additional adsorption filter material 8 is connected, in particular sewn, to the layers 2, 3, 4 by means of the seam 7 (the same seam 7).

[0087] According to the invention, the seam 7 is produced or formed by sewing, in particular using at least one yarn and / or thread. This ensures a resilient and thus stable connection between the respective layers or the additional adsorption filter material.

[0088] In particular, the seam 7 can be produced or formed by repeatedly guiding at least one yarn or thread through the layers 2, 3, 4 and the additional adsorption filter material 8.

[0089] In general, it can be provided according to the invention that the yarn or thread of the seam 7 comprises or consists of a material, in particular textile fiber material, from the group of natural materials and synthetic materials, preferably selected from the group 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; viscoses; and mixtures or combinations thereof.

[0090] According to the invention, in this context, the yarn or thread of the seam 7 can be designed as a monofilament yarn or as a multifilament yarn.

[0091] The multifilament yarn can be based on corresponding single filaments.

[0092] The special seam design, as provided for in the present invention, makes it possible to avoid, in particular, the use of adhesives to connect the respective components in the connection area or to form weld seams or the like. In particular, this avoids the disadvantages associated with the use of adhesives or weld seams, such as insufficient flexibility or elasticity, as well as sometimes insufficient stability, for example, due to material incompatibilities or the like.

[0093] Against this background, it is therefore provided according to the invention in particular that the seam 7 is not designed as an adhesive seam (adhesive connection or adhesive connection seam) or at least substantially has no adhesive or is not formed by gluing the layers 2, 3, 4 and the additional adsorption filter material 8.

[0094] Likewise, it is particularly provided according to the invention that the seam 7 is not designed as a weld seam or is not formed by welding the layers 2, 3, 4 and the additional adsorption filter material 8.

[0095] In this context, the invention is particularly such that, through the targeted and purposeful use with the special arrangement of the additional adsorption filter material 8 when the protective clothing 1 is worn or in use, harmful or toxic substances acting on the connection or seam area 5, 6 can be prevented from entering or passing through the protective clothing 1 according to the invention by being effectively absorbed by the additional adsorption filter material 8. Thus, according to the invention, further protection is also ensured, particularly in the underlying connection or seam area 5, 6, with the fixation of the non-textile and in particular polymer- or plastic-based third layer 4, which is penetrated or punctured by the seam-forming yarn or thread, which represents a vulnerable entry point for harmful or toxic substances.

[0096] According to the invention, a connection of the respective layers 2, 3, 4 or components is thus provided which is both mechanically stable and capable of withstanding force and which is also protected against the entry or passage of harmful or toxic substances.

[0097] According to a particularly preferred embodiment of the invention, the additional adsorption filter material 8 comprises an adsorption layer 8a and a textile carrier layer 8b, as particularly illustrated in Fig. 8. Furthermore, the additional adsorption filter material 8 may also comprise further layers, as defined in detail below (see in particular Fig. 8 A2, B2, C2, and D2).

[0098] As illustrated in particular in Fig. 9A and also in Fig. 1 to Fig. 6A or Fig. 6B, according to the invention it is particularly such that the additional adsorption filter material 8 is designed flat or two-dimensionally, in particular in the form of a strip and / or band or strip-shaped and / or band-shaped.

[0099] In this context, the additional adsorption filter material 8 can have a width b in the range from 2 mm to 50 mm, in particular in the range from 4 mm to 35 mm, preferably in the range from 6 mm to 30 mm, preferably in the range from 8 mm to 25 mm, particularly preferably in the range from 10 mm to 20 mm.

[0100] Due to the strip-shaped or band-shaped design of the additional adsorption filter material 8, a corresponding positioning or arrangement of the additional adsorption filter material 8 along the course of the common seam 7 can be achieved with optimized material use (cf. e.g. Fig. 9A), equally accompanied by the guarantee of a corresponding protective function against the entry or passage of harmful or toxic substances along the seam 7. According to the invention, it is therefore provided in particular that the additional adsorption filter material 8 is designed in the form of a strip and / or band or strip-shaped and / or band-shaped and is arranged along the seam 7, in particular along the seam course of the seam 7 (cf. e.g. Fig. 9A or 9B).

[0101] According to the invention, the seam 7 is arranged or configured in particular such that the seam 7 engages, in particular penetrates and / or passes through, the additional adsorption filter material 8. This ensures, in particular, that harmful or toxic substances penetrating through the seam 7 can be directly absorbed by the additional adsorption filter material 8, so that they do not penetrate the protective clothing 1. This also results in a corresponding reduction in load, in particular on the first layer 2 in the form of the underlying adsorption filter material 8 or the corresponding inner layer.

[0102] In a corresponding manner, according to the invention, the seam 7 also encompasses the first layer 2, the second layer 3 and the third layer 4, in particular penetrating or passing through each of them.

[0103] As can be seen in particular from Fig. 9A and 9B, it is provided in particular according to the invention that the additional adsorption filter material 8 is arranged and / or positioned at least substantially completely along the seam 7, in particular along the seam course of the seam 7, and / or extends at least substantially completely along the seam 7, in particular along the seam course of the seam 7.

[0104] In particular, the invention provides that the seam 7 is connected to the additional adsorption filter material 8 along at least substantially its entire seam length and / or encompasses the additional adsorption filter material 8. This ensures the most comprehensive possible protective function by the additional adsorption filter material 8.

[0105] As illustrated, for example, in Fig. 1 to Fig. 6A or Fig. 6B as well as in Figs. 9A and 9B, it is particularly provided according to the invention that the additional adsorption filter material 8 extends on both sides along the seam 7, in particular on both sides of the seam path of the seam 7. Furthermore, it can be provided according to the invention that the opposite edges of the additional adsorption filter material 8 running and / or arranged along the seam 7, in particular along the seam path of the seam 7, are each spaced from the seam 7, in particular independently of one another. In other words, it is particularly provided according to the invention that the seam 7 is flanked along its path, in particular on both sides, by the additional adsorption filter material 8.

[0106] This means that harmful or toxic substances penetrating along the seam 7 can be absorbed particularly effectively by the additional adsorption filter material 8. In particular, this results in a uniform distribution of any penetrating harmful or toxic substances in the additional adsorption filter material 8, so that the adjacent layers, in particular the first layer 2, are also sustainably relieved of contamination with harmful and toxic substances, accompanied by overall improved protection.

[0107] In this context, it can be provided in particular that the opposite edges of the additional adsorption filter material 8 running and / or arranged along the seam 7, in particular along the seam profile of the seam 7, in particular independently of one another, each have a distance from the seam 7, preferably perpendicular to the seam profile of the seam 7, of at least 1 mm, in particular at least 2 mm, preferably at least

[0108] 3 mm, preferably at least 4 mm, particularly preferably at least 5 mm.

[0109] Likewise, it can be provided according to the invention that the opposite edges of the additional adsorption filter material 8, which run and / or are arranged along the seam 7, in particular along the seam profile of the seam 7, in particular independently of one another, each have a distance from the seam 7, preferably perpendicular to the seam profile of the seam 7, in the range from 1 mm to 20 mm, in particular in the range from 2 mm to 17.5 mm, preferably in the range from 3 mm to 15 mm, preferably in the range from

[0110] 4 mm to 12.5 mm, particularly preferably in the range of 5 mm to 10 mm.

[0111] In this context, it has equally proven advantageous within the scope of the present invention that the opposite edges of the additional adsorption filter material 8 running and / or arranged along the seam 7, in particular along the seam profile of the seam 7, preferably perpendicular to the seam profile of the seam 7, have at least substantially an identical distance from the seam 7. In particular, it can be provided according to the invention that the seam 7 runs along the longitudinal profile of the additional adsorption filter material 8 through the additional adsorption filter material 8 and / or is arranged and / or positioned at least substantially centrally to the additional adsorption filter material 8. This can also be seen illustratively in Fig. 1 to Fig. 6A, Fig. 6B and Figs. 9A and 9B.

[0112] In general, it can equally be provided according to the invention that the additional adsorption filter material 8 is arranged or provided in the seam region 6 and also in the connection region 5. In particular, the additional adsorption filter material 8 can also extend into the connection region 5, as illustrated, for example, in Fig. 1 to Fig. 6A / B. By this measure according to the invention, the protection against harmful or toxic substances can be further increased or adapted. In particular, by adapting the surface area of ​​the additional adsorption filter material 8, its adsorption capacity can be increased or tailored.

[0113] In this context, the additional adsorption filter material 8 can cover the connecting area 5 at least partially and / or in sections, preferably at least substantially completely.

[0114] In general, it can be provided according to the invention that the additional adsorption filter material 8 also extends beyond the connecting region 5, in particular at least on one side or on both sides.

[0115] As shown in particular in Fig. 1 to Fig. 6A / B, it is particularly provided according to the invention that the layers 2, 3, 4 and the additional adsorption filter material 8 are arranged or positioned in a stack in the connecting region 5, in particular in the seam region 6. According to the invention, this can in particular be such that the layers 2, 3, 4 are arranged overlapping one another in the connecting region 5, in particular in the seam region 6. According to the invention, the arrangement of the respective layers in the form of the first layer 2, the second layer 3 and the third layer 4 on the one hand and of the additional adsorption filter material 8 on the other hand can vary, in particular against the background of the intended use of the protective clothing 1 according to the invention or the concrete functional design of the connecting region with the third layer 4 as a sealing element against body sections of a wearer orUser or other equipment, such as an ABC protective mask (see, for example, Fig. 9A and Fig. 9B). In general, within the scope of the present invention, it can be provided in this context that the additional adsorption filter material 8 in the connection region 5, in particular in the seam region 6, is in direct contact with the third layer 4 and / or directly adjoins and / or rests on the third layer 4, as indicated, for example, in Fig. 1 or Fig. 3. The term "directly" is to be understood in particular to mean that no further layers or the additional adsorption filter material 8 is arranged or positioned between the respective referenced layers.

[0116] In particular, in this context, the seam 7 can connect the additional adsorption filter material 8 to the third layer 4 directly (ie without further intermediate layers), as shown, for example, equally in Fig. 1 and Fig. 2.

[0117] In general, the respective contact surfaces refer to the underlying sections of the respective main extension planes of the mentioned layers 2, 3, 4 or the additional adsorption filter material 8.

[0118] In general, with regard to the arrangement or positioning of the layers 2, 3, 4 or of the additional adsorption filter material 8, it can be provided according to the invention that in the connection region 5, in particular in the seam region 6, the additional adsorption filter material 8 is arranged and / or positioned in the wearing and / or use state of the protective clothing 1 on the surface or side facing the wearer and / or user of the protective clothing 1 or the surface or side facing away from it, preferably on the surface or side of the third layer 4 facing the wearer and / or user of the protective clothing 1.

[0119] In particular, in the connecting region 5, in particular in the seam region 6, the additional adsorption filter material 8 can be arranged and / or positioned in the wearing and / or use state of the protective clothing 1 on the surface or side facing away from a source of harmful and / or toxic substances or on the surface or side facing towards a source of harmful and / or toxic substances, preferably on the surface or side facing away from a source of harmful and / or toxic substances, of the third layer 4.

[0120] In other words, according to the invention, the additional adsorption filter material 8 is arranged or positioned, so to speak, behind or downstream of a source of pollutants or toxins, or facing the user or wearer, with respect to the third layer 3. As a result, pollutants or toxins penetrating the third layer 4 in the form of the air-impermeable plastic or rubber material, for example, in the area of ​​the seam perforations, are effectively absorbed by the additional adsorption filter material 8 without premature depletion.

[0121] The respective embodiments with the specific arrangement or positioning of the layers 2, 3, 4 or the additional adsorption filter material 8 in the connecting region 5 or in the seam region 6 are discussed below.

[0177] The previously described overlapping of the first layer 2 and the second layer 3 is also particularly advantageous according to the invention in that the seam 7 used for this purpose also equally encompasses the third layer 4 and the additional adsorption filter material 8 or connects them to the further layers 2, 3. The overlapping of the first layer 2 and the second layer 3 is particularly advantageous in that the seam 7 can be designed such that only the inner sections of the first layer 2 and the second layer 3 are encompassed, thus providing a covering by the respective outwardly extending layer sections, which leads to a further improvement in the protective function against harmful or toxic substances in the connection area 5, since the seam 7 is, so to speak, additionally covered on the outside (cf. in particular Fig. 6A).In this context, the invention can equally provide for the first layer 2 and / or the second layer 3 to be hemmed independently of one another in the connecting region 5. This can increase the stability of the respective edge region of the first layer 2 or the second layer 3.

[0178] 4 to 6A / B as well as Fig. 9C further show a preferred embodiment of the present invention in that the first layer 2 and / or the second layer 3, independently of one another, are folded over and / or turned over in the connecting region 5, in particular folded over and / or turned over at the edge. According to a preferred embodiment of the invention, this is particularly such that both the first layer 2 and the second layer 3 are folded over or turned over in the connecting region 5. In this context, the folding or turning over relates in particular to the edge region of the first layer 2 or the second layer 3. With regard to the folding or turning overBy folding the respective layers 2, 3 at the connecting region 5, the stability of the connection of the components in the connecting region 5 can be increased, in particular since in this context it is possible to proceed in such a way that the seam 7 covers the respective layer 2, 3 several times, as shown in Fig. 4 for the second layer 3 and as shown in Fig. 5 for the first layer 2 and the second layer 3.

In this regard, the invention particularly provides that the third layer 4 with the additional adsorption filter material 8 is arranged and / or positioned between the first layer 2 and the second layer 3, preferably as defined above.

[0180] According to this embodiment, the additional adsorption filter material 8 is in direct contact with the third layer 4, and the third layer 4 with the additional adsorption filter material 8 is, so to speak, enclosed by the first layer 2 and the second layer 3, wherein the layers 2, 3 are folded over in the connection region 5 in the direction of the third layer 4 with the additional adsorption filter material 8. This is also illustrated in Fig. 9C. In this case, it can be provided according to the invention, in particular, as shown in Fig.6A / B shows that the seam 7, with respect to the first layer 2 and the second layer 3, only covers the folded and / or turned-over areas of the first layer 2 and the second layer 3, in particular the folded and / or turned-over areas of the first layer 2 and the second layer 3 that are in direct contact with the third layer 4 or the additional adsorption filter material 8, and connects them to the third layer 4 and the additional adsorption filter material 8.

In other words, it can be provided according to the invention that the seam 7 in the connection region, with respect to one of the layers 2, 3, encompasses both the folded and the non-folded region of one of these layers 2, 3, in particular the second layer 3, and with respect to the other layer, in particular the first layer 2, encompasses only the folded region and / or the region in direct contact with the additional adsorption filter material 8 or the third layer 4 (see in particular Fig. 4).

[0182] In particular, the area of ​​the first layer 2 which is not folded over and, when worn, is oriented towards the wearer or user of the protective clothing 1 is not covered by the seam 7, so that the seam 7 is, so to speak, additionally covered on the inside by the area of ​​the first layer 2 which is not covered by the seam, as illustrated in Fig. 4 and Fig. 6A / B. As a result, the protective function against harmful or toxic substances in the binding area or in relation to the seam 7 can be further increased, since any harmful or toxic substances penetrating through the seam 7 can be further absorbed by the area of ​​the first layer 2 which is not covered by the seam in the form of the corresponding adsorption filter material 8.

[0183] With regard to the folding or turning over of the layers 2, 3, the situation is particularly such that the respectively folded or turned over area of ​​a respective layer 2, 3 and the respectively non-folded or non-folded area of ​​a respective layer 2, 3 lie on top of one another, so that the respectively non-folded or non-folded area (section) of a respective layer 2, 3 is, so to speak, that section or area of ​​the main extension plane of the respective layer 2, 3 which rests on or covers the corresponding folded or folded area (section).

The present invention is illustrated by the following exemplary embodiments, which, however, are not intended to limit the present invention in any way.

[0490] EXAMPLES OF IMPLEMENTATION:

[0491] Versions A: Materials

[0492] Different protective materials according to the invention or related protective clothing are produced, namely protective materials or clothing according to the invention (material A1, A2, A3 and B1, B2 and B3) on the one hand and comparison protective materials or clothing (material C1, D1 and E1) on the other hand.

[0493] For the materials A1, A2, and A3 according to the invention, a textile sheet material in the form of a laminate is used for the first layer, which comprises a textile carrier layer, an adsorption layer with activated carbon particles applied thereto, a particle or aerosol filter layer applied to the adsorption layer, and a cover or spacer or intermediate layer applied to this layer. The carrier layer is in the form of a knitted fabric based on a cotton / elastane blend with antibacterial treatment and has a basis weight of approximately 115 g / m² 2For the adsorption layer, adsorbent particles in the form of particulate activated carbon in spherical form (activated carbon particles in spherical form) are used. The activated carbon used has a total pore volume according to Gurvich of approximately 0.8 cm 3 / g, a specific BET surface area of ​​about 1,900 m 2 / g and an average pore diameter of approximately 25 nm. Furthermore, the spherical activated carbon used has an average particle diameter D50 of approximately 0.25 mm. The particle or aerosol filter layer is also in the form of a polyurethane fleece and has a surface weight of approximately 30 g / m 2 A polyamide-based knit fabric is used as the cover, spacer, or intermediate layer. This layer has a surface weight of approximately 54 g / m 2 on.

[0494] For the inventive materials B1, B2, and B3, as well as the comparative materials C1, D1, and E1, a corresponding textile adsorption filter material is used for the first layer therein, but with the proviso that the relevant material, in contrast to the first layer of materials A1, A2, and A3, does not comprise a particle or aerosol filter layer. The first layer for materials B1, B2, B3, as well as C1, D1, and E1, is thus based on a laminate, which in turn is formed from a textile carrier layer, as previously mentioned, an adsorption layer, as previously mentioned, and a cover, spacer, or intermediate layer, as previously mentioned (and thus does not have a particle or aerosol filter layer). Furthermore, for all materials A1, A2, A3 or B1, B2 and B3 as well as C1, D1 and E1, a second layer in the form of a textile, air-permeable covering material based on para-aramid (Nomex®) is used.The second layer is thus flame-retardant and / or flame-retardant and / or fire-resistant and / or flame-resistant. Furthermore, the material of the second layer exhibits oleophobic or hydrophobic properties through an impregnation or coating based on a fluorinated polymer.

[0495] For all materials A1, A2 and A3 as well as B1, B2 and B3 as well as C1, D1 and E1, the third layer is formed in the form of a non-textile polymer-based or plastic-based and air-impermeable surface material based on butyl rubber.

[0496] Furthermore, with regard to the additional adsorption filter material used for materials A1, A2, and A3, as well as B1, B2, and B3, this is formed or cut in a band- or strip-shaped manner, wherein the additional adsorption filter material is made of the same material as the textile sheet material used for the first layer of materials A1, A2, and A3. The additional adsorption filter material thus equally comprises a textile carrier layer, an adsorption layer with activated carbon particles applied thereto, a particle or aerosol filter layer applied to the adsorption layer, and a cover, spacer, or intermediate layer applied to this layer, as previously defined for materials A1, A2, and A3 with respect to the first layer.

[0497] In the case of materials A1 and B1, the connecting region is further designed such that the third layer is arranged on the surface or side of the second layer facing away from the first layer and after which the additional adsorption filter material is positioned on the surface or side of the third layer facing away from the second layer and thus on the outside on or above the third layer (layer sequence in the connecting region: first layer, second layer, additional adsorption filter material, third layer), wherein the first, second and third layers as well as the additional adsorption filter material are connected in the connecting region with a common seam (see also embodiment according to Fig. 3).A comparable structure is realized for material C1, but with the proviso that material C1 does not have any additional adsorption filter material (layer sequence in the connection area: first layer, second layer, third layer); in the connection area, these layers are similarly connected with a common seam.

[0498] For material D1, a similar structure is implemented in the joining area; the first layer, second layer, and third layer are joined with a common seam. Furthermore, for material D1, instead of the additional adsorption filter material, a non-textile, polymer-based, air- and water-impermeable sealing tape is applied to the outside of the joining area (i.e., on the side or surface of the third layer facing away from the second layer) using an adhesive or pressure-sensitive adhesive applied over the entire area, covering the outside of the seam or seam area (layer sequence in the joining area: first layer, second layer, third layer, non-textile sealing tape).

[0499] For materials A2 and B2, the third layer with the additional adsorption filter material is arranged between the first layer and the second layer, with the additional adsorption filter material being positioned between the third layer and the first layer and thus, so to speak, on the inside of or below the third layer (layer sequence in the connecting area: first layer, additional adsorption filter material, third layer, second layer); moreover, the first, second, and third layers are connected in the connecting area with the additional adsorption filter material with a common seam (see Fig. 1).

[0500] In the case of materials A3 and B3, the third layer with the additional adsorption filter material is arranged equally between the first layer and the second layer, with the additional adsorption filter material being positioned between the third layer and the first layer and thus, so to speak, on the inside of or below the third layer; furthermore, the first layer and the second layer are each folded over in the direction of the third layer in the connecting region; moreover, the common seam which connects the first, second and third layers as well as the additional adsorption filter material to one another is designed in such a way that it only covers the folded over area or section of the first layer or the second layer which is (directly) in contact with the third layer or the additional adsorption filter material, and the first orsecond layer with the third layer and the additional adsorption filter material, so that the non-folded area of ​​the first layer or the second layer in the connection area is not covered by the common seam and the seam is, so to speak, additionally covered by these areas - layer sequence in the connection area: first layer with non-folded area (not covered by the seam) and folded area (covered by the seam), additional adsorption filter material, third layer, second layer with non-folded area (not covered by the seam) and folded area (covered by the seam) (cf. Fig. 6A).

[0501] Material E1 corresponds to material A3 with the proviso that instead of the additional adsorption filter material, a textile surface material (reinforcement layer or ply) without adsorption material and with hydrophilic and oleophilic properties is used, based on a nonwoven material made of a mixture of polyamide and polyester (70 : 30) with a basis weight of 60 g / m 2 , based on WO 2019 / 129656 A1 or EP 3 731 939 A1.

[0502] Explanation B: Investigations

[0503] For all of the aforementioned protective materials A to C, the protective function against harmful or toxic substances (here specifically: mustard gas, HD) is examined:

[0504] The protective function against chemical warfare agents (mustard gas, HD) is determined on the basis of the so-called standardized diffusion flow test with applied drops ("Laid Drop Diffusive Flow Test"). For this purpose, the respective previously described materials A1, A2, A3 or B1, B2 and B3 as well as C1, D1 and E1 (sample area: 10 cm each) are 2) in a test cell over a PE membrane (10 pm), which simulates human skin. Furthermore, chemical warfare agent drops (8 drops of mustard gas per material, each with a volume of 1 pl) are applied to defined areas of the materials to be tested using a cannula (primarily in the connection area on the side of the material where the second layer is positioned). Test conditions: relative humidity of maximum 5% RH, temperature of 23 °C, mustard gas exposure for 24 h (test duration), flow under the material: 100 ml / min, flow above the material: 0.5 m / s, flow through the material: 0 cm / s. The air flow under the sample is drawn through a wash bottle. As part of the tests, the cumulative breakthrough is determined in pg / m using gas chromatography (GC / FPD). 2These tests simulate the diffusion of liquid warfare agent through the textile protective material without convection and thereby simulate the flat contact of the protective clothing with the skin, the latter being simulated by the PE membrane. Version C: Results

[0505] Using the previously described test method, the following values ​​(cumulative breakthrough values) can be determined within the framework of the Laid Drop Diffusive Flow Test for the materials A1, A2, A3 or B1, B2 and B3 as well as C1, D1 and E1, which were also described previously:

[0506] 1. Materials A1, A2, A3 (first layer with particle or aerosol filter layer): 2. Materials B1, B2, B3 (first layer without particle or aerosol filter layer):

[0507] 3. Materials C1, D1, E1 (first layer without particle or aerosol filter layer): 4. Further tests were conducted on materials B1 and D1 with regard to the resistance and stability of the respective materials, taking into account washing and drying processes (wash cycles). Materials B1 and D1 were subjected to all defined washing and drying processes based on the DIN ISO 6330 4M standard (drying F). After 10 wash cycles, the invention material B1 exhibited a cumulative breakthrough value of 0.57 in the Laid Drop Diffusive Flow Test, while material D1 achieved a value of > 5.9. In particular, material D1 exhibited material damage with delamination of the non-textile sealing tape.

[0508] Overall, the tests demonstrate the excellent protective properties of the inventive materials A1, A2 and A3 or B1, B2 and B3 compared to the comparison materials. For the comparison material C1, relatively poor protective properties were observed, in particular there is a penetration of toxic substances along the connecting seam. The material D1 with the non-textile sealing tape also only has reduced mechanical resistance and wash resistance, accompanied by a reduction in protective performance after corresponding washing treatment. The material E1 with the hydrophilic and oleophilic reinforcement tape also has poorer protective properties than the inventive materials. In particular, the hydrophilic or oleophilic reinforcement tape does not have sufficient properties that could lead to a sustained absorption of toxic substances. Rather, there is a transfer of toxic substances.

[0509] With regard to the materials according to the invention, a further improvement in protective performance can be observed through the additional use of a particle or aerosol filter layer for the first layer, since only a smaller portion of the toxic substance can penetrate the first layer. In particular, the particle or aerosol filter layer also further relieves the load on the adsorption layer of the first layer. Furthermore, improved protective performance is observed for an arrangement of the third layer with the additional adsorption filter material between the first layer on the one hand and the second layer on the other, with the additional adsorption filter material being arranged, so to speak, below the third layer (cf. materials A2 and B2). The protective performance can be further improved with appropriate folding of the first and second layers and the special seam design (cf. materials A3 and B3).Overall, the above statements demonstrate the excellent protective properties of the materials according to the invention. In particular, the present invention provides an effective technical solution for sealing the transition area between textile layers or components on the one hand and a non-textile component or layer on the other.
