Description
[0001] Protective materials and clothing with reactive coating
[0002] The present invention relates to the technical field of ABC protection or CBRN protection and in particular to the technical field of 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 sectors.
[0003] In particular, the present invention relates to ABC protective materials or clothing, or CBRN protective materials or clothing (where ABC = atomic, biological, and chemical, and, synonymously, CBRN = chemical, biological, radiological, and nuclear; the terms ABC on the one hand and CBRN on the other 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 ABC or CBRN protective clothing, such as that which can be used in particular for military purposes and also for civilian purposes (for example, in the field of hazard prevention, firefighting, or disaster relief, or the like).
[0004] The present invention relates to such textile protective materials, a method for producing these textile protective materials, and uses of the textile protective materials for the production of protective equipment and / or protective articles of all kinds.
[0005] In this sense, the present invention also relates to protective equipment and / or protective articles of all kinds based on protective materials according to the present invention.
[0006] Last but not least, the present invention relates to the use of a metal-based catalytically active component in the form of a porous solid, preferably with a net-like structure, particularly preferably as a xerogel, in a textile protective material.
[0007] Chemical, biological, and nuclear toxins and warfare agents generally pose a high risk to individuals who come into contact with them, such as soldiers in combat. Often, even small quantities or concentrations of these substances are sufficient to cause lasting health problems or even death. Within the group of chemical toxins and warfare agents, in particular, there are a number of substances that are absorbed through the skin upon contact and can cause serious physical damage even in small quantities or concentrations. Well-known examples include effervescent mustard gas and the nerve agent sarin. Individuals who may come into contact with such highly toxic substances must wear appropriate protective clothing or be protected by suitable protective materials against these substances and toxins.
[0008] This also applies in principle to biological warfare agents and toxins, such as bacteria, viruses, or toxins of biological origin, which likewise lead to lasting health problems upon contact, especially direct or indirect contact (i.e., through subsequent absorption into the body, for example, via mucous membranes or the like). Finally, direct contact with or contamination from radioactive substances, especially in the form of radioactive particles or the like, must also be avoided.
[0009] Regarding the aforementioned harmful or toxic substances, especially chemical warfare agents, these can also be present in both gaseous form and in the form of sometimes finely dispersed particles, for example as aerosols or the like, which poses a further challenge for the protective materials to be provided with regard to the neutralization of the toxic or warfare agents in question.
[0010] To ensure a certain level of protection against the aforementioned toxic or chemical warfare agents, air- and water-vapor-impermeable protective suits or similar garments are known. These are generally equipped with a rubber layer impermeable to toxic or chemical warfare agents, particularly those of the aforementioned type. However, these protective suits have the disadvantage that, when worn or in use (for example, during combat operations involving high physical exertion on the wearer), heat can build up very quickly due to the lack of air and water vapor permeability, i.e., insufficient moisture-regulating and thermoregulating properties.
[0011] Furthermore, prior art employs protective materials equipped with an airtight, yet water vapor-permeable membrane. This membrane also serves as a barrier against toxic substances. Such a protective material is described, for example, in WO 96 / 37365 A1 and in US 5,743,775 A and DE 195 18 683 A1, which belong to the same patent family. Besides impermeable (e.g., suits made of butyl rubber or suits with a membrane) or (partially) permeable, airtight systems, CBRN protective clothing can also be based on adsorptive filter systems, particularly those based on activated carbon (e.g., powdered carbon, activated carbon fibers, or spherical carbon, etc.).While impermeable systems offer relatively good protection against chemical and biological toxins as well as warfare agents – at the expense of wearing comfort – permeable, adsorptive protective suits have disadvantages on the one hand with regard to the absolute absorption capacity for chemical warfare agents and on the other hand with regard to the protective effect against biological pollutants.
[0012] To counteract this, permeable adsorptive filter systems, especially those based on activated carbon, are equipped, for example, with a catalytically active component by impregnating the activated carbon with a catalyst that has a particularly biocidal or biostatic effect, for example, based on metals or metal compounds.
[0013] Such a protective material is described, for example, in DE 195 19 869 A1, which describes a multi-layered, textile, gas-permeable filter material with an adsorption layer based on activated carbon, particularly in the form of carbonized fibers. The activated carbon is impregnated with a metallic catalyst. A disadvantage of this protective material or filter system is that the impregnation with the catalyst results in a loss of some of the adsorption capacity required for adsorbing and thus neutralizing chemical pollutants. The impregnation process therefore negatively impacts the performance of the activated carbon used. Furthermore, impregnating the activated carbon material is relatively complex, which often complicates the manufacturing process for the activated carbon, especially the activation process.Furthermore, impregnation with the catalyst does not always achieve the desired effectiveness against biological pollutants or microorganisms. Finally, the impregnation process requires relatively large quantities of the catalyst metal.
[0014] Another approach is to equip permeable adsorptive filter systems with additional amounts of adsorptively reactive substances, such as metal-organic frameworks (MOFs). A corresponding sorption filter material is described in WO 2009 / 056184 A1. In contrast to DE 195 19 869 A1, a preferred embodiment here involves additionally coating an activated carbon fiber sheet structure with MOF-based sorbent particles, the latter providing catalytic activity against pollutants. In this way, the adsorption capacity of the activated carbon fibers is fully maintained. However, the high costs and manufacturing effort are disadvantages, particularly since the MOF particles must be used in addition to the activated carbon fibers, and a complex bonding process is required to integrate the MOF particles into or onto the protective material.The additional particle layer of MOF particles also significantly increases the basis weight of the protective material, resulting in a greater weight of the protective clothing and a corresponding reduction in wearing comfort.
[0015] Another disadvantage remains that absorption capacity limits for the adsorptively reactive substances can be reached, potentially leading to a loss of functionality of the protective material. Furthermore, there is a risk of inactivation of the absorption materials, especially the metal-organic framework compounds, for example, through mechanical stress on the protective material.
[0016] Against this background, further solutions are needed that provide reliable, robust and long-lasting protection against chemical, biological and nuclear toxins or warfare agents.
[0017] One object of the present invention is therefore to provide an adsorption filter material or a protective material that largely avoids or at least mitigates the disadvantages of the prior art described above. In particular, such an adsorption filter or protective material should be characterized by an ABC protection function (CBRN protection function) and preferably be suitable for use in the civilian and / or military sector, as well as for the manufacture of ABC protective materials of all kinds, such as ABC protective clothing and the like, as well as filters and filter materials.
[0018] A further object of the present invention is to provide a permeable, in particular gas- or air-permeable, adsorption filter or protective material, especially of the aforementioned type, which is reliably and persistently effective in providing protection against both chemical toxins or pollutants, especially chemical warfare agents, and biological pollutants (e.g., microorganisms such as bacteria, viruses, and fungi), especially biological warfare agents. Furthermore, an object of the present invention is also to provide such a permeable, in particular gas- or air-permeable, adsorption filter or protective material, especially of the aforementioned type, which offers acceptable or, ideally, comfortable wear, particularly over extended periods and / or during periods of increased physical exertion by the wearer.
[0019] To solve the problem described above, the present invention therefore proposes – according to a first aspect of the present invention – a textile protective material according to the invention, preferably a textile reactive adsorption filter material, with a protective function against chemical, biological and / or radioactive pollutants or toxins, preferably against chemical warfare agents, in particular ABC and / or CBRN protective material, according to claim 1; further advantageous developments and embodiments of this aspect of the invention are the subject of the corresponding dependent and sub-claims relating to the protective material according to the invention.
[0020] A further object of the present invention – according to a second aspect of the present invention – is a method for producing a textile protective material, preferably a textile reactive adsorption filter material, with a protective function against chemical, biological and / or radioactive pollutants or toxins, preferably against chemical warfare agents, in particular ABC and / or CBRN protective material, according to the claim relating thereto. Further advantageous embodiments and configurations of this aspect of the invention are the subject of the respective dependent claims.
[0021] Yet another subject matter of the present invention - according to a third aspect of the present invention - is the use of a protective material according to the present invention for the manufacture of protective equipment and / or protective articles of all kinds according to the claim relating thereto.
[0022] A further subject matter of the present invention – according to a fourth aspect of the present invention – is protective equipment and / or protective articles of all kinds, particularly for the civilian or military sector, preferably with a protective function against chemical, biological, and / or radioactive pollutants or toxins, preferably against chemical warfare agents, in particular ABC and / or CBRN protection, according to the relevant claim. Furthermore, a further subject matter of the present invention – according to a fifth aspect of the present invention – is the use of a metal-based catalytically active component in the form of a porous solid, preferably with a network-like structure, particularly preferably as a xerogel, in a textile protective material, according to the relevant claim.Further advantageous developments and embodiments of this aspect of the invention are the subject of the corresponding dependent claims.

[0029] 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.
[0030] The subject matter of the present invention – according to a first aspect of the present invention – is a textile protective material, preferably a textile reactive adsorption filter material, with a protective function against chemical, biological and / or radioactive pollutants or toxins, preferably against chemical warfare agents, in particular ABC and / or CBRN protective material, wherein the textile protective material comprises a combination of a metal-based catalytically active component and a particulate adsorbent, and wherein the textile protective material has a multilayer structure and / or is designed as a multilayer textile material, preferably a composite material, comprising a plurality of layers arranged on top of each other, preferably interconnected, layers, wherein the textile protective material comprises the following layers, preferably in the sequence mentioned below:
[0031] (a) optionally a textile outer layer (top layer), wherein the textile outer layer is and / or is formed as a preferably gas-permeable textile surface structure,
[0032] (b) a textile reactive layer, in particular a textile reactive layer arranged on one side, in particular on the inside, of the textile outer layer, wherein the textile reactive layer is and / or is formed as a preferably gas-permeable, textile sheet structure and comprises at least one metal-based catalytically active component, preferably coated and / or impregnated with the metal-based catalytically active component, preferably (only) on one side, particularly preferably (only) on the inside of the textile reactive layer, wherein the metal-based catalytically active component is and / or is formed in the form of a porous solid, preferably with a network-like structure, particularly preferably as a xerogel,
[0033] (c) an adsorption layer arranged on the textile reactive layer, in particular on the inside of the reactive layer, preferably in a discontinuous form and / or being gas-permeable, wherein the adsorption layer comprises or is formed from a plurality of individual adsorber particles,
[0034] (d) an inner layer arranged on the adsorption layer, in particular on the inside of the adsorption layer, wherein the inner layer is preferably designed as a gas-permeable textile surface structure.
[0035] The applicant has surprisingly discovered that protective materials with the inventive structure and configuration, specifically due to the specific combination of a metal-based catalytically active component and a particulate adsorbent, exhibit advantageous protective properties against chemical, biological, and / or radioactive pollutants or toxins. This advantageous protective function is expressed in a high and / or long-lasting absorption or neutralization capacity for pollutants or toxins. The absorption or neutralization capacity for pollutants or toxins (e.g., chemical warfare agents, particularly from the phosphate ester group) is especially higher than that of protective materials containing only an active component.At the same time, the protective function is also higher due to the combination of the catalytically active component and the particulate adsorbent than would have been expected for the sum of the individual materials. This can be attributed in particular to the preferably consecutive arrangement of the materials and the advantageous combination of two different mechanisms of action, which together allow for a significantly more efficient inactivation of pollutants and toxins than is the case for the individual substances. Thus, an increase in the absorption capacity for pollutants and toxins is observed, so that the present invention provides a protective material with generally advantageous application properties.
[0036] In this context, it is particularly advantageous that the metal-based component relies on a catalytic mechanism, enabling a high neutralization performance or a high degree of deactivation of pollutants. Simultaneously, it is advantageous that fatigue or saturation of the metal-based component does not occur, or at most only very slowly or over a comparatively long period, due to its catalytic function. This allows for a particularly long-lasting and efficient protective effect.
[0037] In combination with the particulate adsorbent, the protective material according to the invention thus comprises two different, mutually complementary active components which, due to their different modes of action, achieve a very reliable protective function of the material. These are advantageously based on the catalytic deactivation of pollutants as well as their simultaneous adsorption. This allows for a kind of dual protection or a doubly enhanced protective effect, which significantly increases the protection of the substrate compared to conventional protective materials. In particular, the combination of active materials with different mechanisms of action achieves a complex or multidimensional protection, enabling a broader or more extensive protective effect compared to conventional protective materials.
[0038] Furthermore, the arrangement of the layers of the protective material according to the present invention advantageously results in an enhanced and more reliable protective function. The preferably consecutive arrangement of the reactive layer and the adsorption layer allows for efficient, dense, and comprehensive absorption and / or neutralization of pollutants and toxins. This preferably consecutive arrangement enables particularly effective neutralization and absorption of pollutants and toxins, effectively preventing breakthroughs or capacity exhaustion. The direct arrangement of the metal-based catalytically active component and the particulate adsorbent on top of each other advantageously contributes to the enhanced protective function achieved, especially since pollutants flowing through the material come into effective and largely complete contact with at least one active material, and regularly with both active materials, and are thus effectively neutralized to a high degree.be adsorbed.
[0039] Furthermore, the combination of layers of the protective material according to the invention allows for effective protection of the active materials (catalytically active component and particulate adsorbent) against external, e.g., mechanical, influences, so that the functionality of the active materials is reliably ensured and can be maintained for a long time. In this respect, the overall arrangement of the layers of the protective material according to the invention contributes advantageously to the reliable protective function of the protective material according to the invention.
[0040] At the same time, the individual layers or the protective material as a whole are advantageously designed in such a way that a breathable material is provided, which is advantageously characterized by a high level of wearing comfort combined with a high level of protection.
[0041] Regarding the metal-based catalytically active component in the form of a porous solid, preferably with a network-like structure, and particularly preferably as a xerogel, the following should be noted: Formulating the catalytically active component as a porous solid, preferably with a network-like structure, and particularly preferably as a xerogel, advantageously results in a large catalytically active surface area. Within a comparatively small area of the textile substrate, a large catalytically active area for neutralizing or deactivating harmful or toxic substances can thus be created, which advantageously increases the protective function of the protective material according to the invention, particularly to a greater extent than would have been expected from a purely surface-based perspective, and also to a greater extent than if, for example, conventional, compact particles of the catalytically active component had been used as a coating or impregnation.
[0042] In contrast to the direct impregnation of the adsorption layer or the individual adsorber particles, which is frequently practiced in the prior art, the invention efficiently avoids direct coating or impregnation of the adsorption layer or the individual adsorber particles, thus preserving the total adsorption capacity. Furthermore, the formation of the metal-based catalytically active component in the form of a porous solid, preferably with a network-like structure, particularly preferably as a xerogel, offers advantages over conventionally produced metal-based catalytically active components in the form of non-porous solids, especially without a network-like structure, as produced according to the prior art, for example, by precipitation, defatting, spraying, etc.The decisive advantage of obtaining the catalytically active components themselves is that significantly higher catalytic activities are achieved, and in addition, a certain adsorptive effect is also produced due to the porosity. This is impressively demonstrated by the exemplary embodiments. Without committing to a specific theory, this effect can possibly be explained by the increase in the active surface area resulting from the porosity, particularly the network-like structure.
[0043] Since the metal-based catalytically active component is in the form of a porous solid, preferably with a network-like structure, and particularly preferably as a xerogel, the porosity also reduces the basis weight while improving catalytic performance. Furthermore, these particles are more mechanically resistant and exhibit, in particular, improved abrasion and burst resistance.
[0044] Overall, this results in a durable protective material with a high adsorption and neutralization capacity for toxic or combat agents, which, due to its high protective function against harmful or toxic substances of the aforementioned type, especially chemical warfare agents, is particularly suitable for use in the field of ABC protection or NBC protection (nuclear, biological, chemical).
[0045] According to the applicable first aspect, the present invention relates to a textile protective material, preferably a textile reactive adsorption filter material, with a protective function against chemical, biological and / or radioactive pollutants or toxins, preferably against chemical warfare agents, in particular ABC and / or CBRN protective material, wherein the textile protective material comprises a combination of a metal-based catalytically active component and a particulate adsorbent, and wherein the textile protective material has a multilayer structure and / or is designed as a multilayer textile material, preferably a composite material, comprising a plurality of layers arranged on top of each other, preferably interconnected, layers, wherein the textile protective material comprises the following layers, preferably in the sequence mentioned below:
[0046] (a) optionally a textile outer layer (top layer), wherein the textile outer layer is and / or is formed as a preferably gas-permeable textile surface structure,
[0047] (b) a textile reactive layer, in particular a textile reactive layer arranged on one side, in particular on the inside, of the textile outer layer, wherein the textile reactive layer is and / or is formed as a preferably gas-permeable, textile sheet structure and comprises at least one metal-based catalytically active component, preferably coated and / or impregnated with the metal-based catalytically active component, preferably (only) on one side, particularly preferably (only) on the inside of the textile reactive layer, wherein the metal-based catalytically active component is and / or is formed in the form of a porous solid, preferably with a network-like structure, particularly preferably as a xerogel,
[0048] (c) an adsorption layer arranged on the textile reactive layer, in particular on the inside of the reactive layer, preferably in a discontinuous form and / or being gas-permeable, wherein the adsorption layer comprises or is formed from a plurality of individual adsorber particles,
[0049] (d) an inner layer arranged on the adsorption layer, in particular on the inside of the adsorption layer, wherein the inner layer is preferably designed as a gas-permeable textile surface structure.
[0050] As regards the metal-based catalytically active component of the reactive layer, it is preferred according to the invention if the metal-based catalytically active component comprises a metal-containing oxide and / or hydroxide, in particular consists of this, preferably being a metal oxide and / or hydroxide.
[0051] In particular, it is provided that the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide, contains at least one metal selected from the group consisting of Si, Ti, Zr, Cu, Ag, Au, Zn, Ni, Pd, Pt, Rh, more specifically selected from the group consisting of Si, Ti, Zr, Ag, Pd, Pt, and more preferably selected from the group consisting of Si, Ti, Zr, and more preferably Zr, preferably wherein the metal-containing oxide and / or hydroxide, more preferably the metal oxide and / or hydroxide, comprises one to six, more specifically two to five, and more preferably two to four, oxygen atoms per metal atom. Within the scope of the present invention, metal-containing oxides and / or hydroxides, as described above, have thus proven to be particularly suitable and effective, especially with regard to catalytic activity or catalytic potential for the deactivation of pollutants and toxins in accordance with the present invention.
[0052] It is equally preferred if the metal-based catalytically active component, in particular the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide, results from and / or is obtained from a sol-gel process.
[0053] If the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide, results from a sol-gel process, a particularly durable bond or connection between the metal-containing oxide and / or hydroxide and the textile substrate can be advantageously achieved. In particular, it is possible to form a chemical bond or connection between the metal-containing oxide and / or hydroxide and the textile substrate, thus advantageously achieving a very stable and durable composite. Furthermore, a uniform and consistent coating or impregnation of the textile substrate is advantageously possible, enabling a suitably dense covering of the substrate with the catalytically active component. This, in turn, advantageously contributes to achieving an effective protective function of the protective material overall, while simultaneously allowing for a material-efficient approach.
[0054] In particular, the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide, is present and / or formed in the form of a porous solid, preferably with a network-like structure, particularly preferably as a xerogel.
[0055] By forming the catalytically active component as a porous solid, preferably with a network-like structure, and particularly preferably as a xerogel, a large catalytically active surface area is advantageously achieved. Within a comparatively small area of the textile substrate, a large catalytically active area for neutralizing or deactivating harmful or toxic substances can thus be created, which advantageously increases the protective function of the protective material according to the invention, particularly to a greater extent than would have been expected from a purely surface-based perspective, and also to a greater extent than if, for example, conventional, compact particles of the catalytically active component had been used as a coating or impregnation.For the metal-based catalytically active component, in particular the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide, it has proven further advantageous if this(s) has a composition according to the general formula (I).

[0073] Components with a chemical composition as described above are characterized by advantageous effectiveness within the scope of the invention.
[0074] According to a preferred embodiment of the present invention, the metal-based catalytically active component, in particular the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide, comprises a hydroxide and / or oxide of silicon, titanium and / or zirconium, in particular of titanium and / or zirconium, preferably of zirconium, and in particular consists thereof.
[0075] It is particularly preferred if the metal-based catalytically active component, in particular the metal-containing oxide and / or hydroxide, preferably comprises the metal oxide and / or hydroxide, zirconium oxide (ZrÜ2) and / or zirconium hydroxide (Zr(OH)4) and / or zirconium oxyhydroxide, and in particular consists of the following.
[0076] For zirconium oxide (ZrÜ2), zirconium hydroxide (Zr(OH)4), and / or zirconium oxyhydroxide, particularly advantageous results regarding the protective effect of the protective materials according to the invention are observed. In particular, it has been shown that zirconium oxide (ZrCh), zirconium hydroxide (Zr(OH)4), and / or zirconium oxyhydroxide exhibit pronounced catalytic activity in the deactivation or neutralization of harmful or toxic substances from the group of phosphonic acid esters, such as sarin, thus ensuring particularly efficient additional protection against such harmful or toxic substances. Furthermore, porous structures that are resilient and durablely bonded to the substrate can be produced with particular efficiency.This allows for reliable bonding of the catalytically active component to the textile carrier material of the reactive layer, thus maximizing the advantages of the protective material according to the invention. At the same time, highly efficient material usage is possible, which has an overall positive effect on the wearing comfort of protective clothing based on the protective material according to the invention.
[0077] Furthermore, it has proven advantageous within the scope of the invention if the metal-based catalytically active component, in particular the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide, preferably the zirconium oxide (ZrÜ2) and / or zirconium hydroxide (Zr(OH)4) and / or zirconium oxyhydroxide, results from and / or is obtained from a sol-gel process.
[0078] As previously stated, it is particularly advantageous if the catalytically active component results from and / or is obtained through a sol-gel process. These advantages are even more pronounced when the active component is in the form of zirconium oxide (ZrCh), zirconium hydroxide (Zr(OH)4), and / or zirconium oxyhydroxide, both resulting from and / or obtained through a sol-gel process. In this context, the aforementioned compounds are characterized by the advantageous formation of porous structures or xerogels when produced through a sol-gel process. This allows for the creation of large catalytically active surfaces, which effectively deactivate or neutralize harmful or toxic substances. This effect is not observed to the same extent when using conventional powders or similar materials.At the same time, a composite of catalytically active component and textile carrier, based in particular on chemical bonds, can be achieved, so that the textile carrier can be efficiently and material-optimized provided with the catalytically optimized component, while at the same time ensuring an effective protective effect based on the catalytically active component.
[0079] It is preferably provided that a metal-organic compound, serving in particular as a precursor, is applied as a sol, in particular a nanosol, and / or as a lyogel, preferably as a sol, in particular a nanosol, to the textile reactive layer (i.e., the textile support for the reactive layer), preferably (only) to one side, particularly preferably (only) to the inside of the textile reactive layer, preferably wherein the sol, in particular a nanosol, of the metal-organic compound serving in particular as a precursor results as a lyogel on the textile reactive layer, preferably (only) on one side, particularly preferably (only) to the inside of the textile reactive layer, and / or preferably wherein the lyogel is transformed into the porous solid, preferably with a network-like structure, preferably into the xerogel, while retaining the metal-based catalytically active component.
[0080] In this way, the durable and resilient composite of textile carrier material and catalytically active component described above can be effectively achieved. At the same time, this approach allows for material-efficient application, thus achieving a balanced ratio between applied material and the protective effect obtained.
[0081] Good results are obtained within the scope of the present invention if the metal-based catalytically active component, in particular the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide, results from and / or is obtained from a metal-organic compound, in particular serving as a precursor; in particular wherein the metal-organic compound has a composition according to the general formula (II)

[0101] When precursor compounds, as described above, are used within the scope of the invention, particularly good results can be achieved for the sol-gel process, the material deposition, and the resulting bond with the textile substrate. In particular, the aforementioned compounds are characterized by advantageous reactivities, enabling a favorable sol-gel formation rate and, especially, chemical bonding with the substrate material. This results to a correspondingly advantageous degree in the formation of the catalytically active component, particularly in the form of an oxide or hydroxide, as well as a permanent bond with the textile substrate.
[0102] Regarding the nature of the reactive layer or the metal-based catalytically active component on the reactive layer, it has proven advantageous within the scope of the invention if the metal-based catalytically active component is comprised and / or present on the textile reactive layer, preferably (only) on one side, particularly preferably (only) on the inside of the textile reactive layer, with a layer thickness in the range of 0.001 pm to 1 pm, in particular from 0.005 pm to 0.5 pm, preferably 0.01 pm to 0.1 pm, particularly preferably 0.02 pm to 0.08 pm.
[0103] The layer thickness is preferably calculated according to the following formula: where:
[0104] Layer thickness in [pm] Application quantity in [g / m²] 2 Fiber surface area in [m²] 2 ] Density act. com. = Density of the metal-based catalytically active component in [g / cm³] 3], and the calculation of the fiber surface area is performed according to the following formula:
[0105] The area of the fiber is equal to n * fiber length * fiber diameter, where:
[0106] Fiber surface area in [m²] 2 ]
[0107] Fiber length in [m]
[0108] Fiber diameter in [m]
[0109] Within the scope of the present invention, comparatively thin layers of the catalytically active component can therefore be produced, while at the same time ensuring that a comparatively high activity or protective effect is achieved for these thin layers.
[0110] Good results are also obtained within the scope of the invention if the metal-based catalytically active component is applied at a quantity in the range of 0.1 g / m². 2 up to 20 g / m² 2 , especially of 0.5 g / m³ 2 up to 15 g / m² 2 , preferably 1 g / m² 2 up to 12 g / m² 2, especially preferably 3 g / m² 2 up to 10 g / m² 2 on the textile reactive layer, preferably (only) on one side, particularly preferably (only) on the inside of the textile reactive layer, is encompassed and / or is present.
[0111] In this context, it has proven effective to calculate the order quantity according to the following formula: where:
[0112] Cwt = coating amount of the metal-based catalytically active component in [g / m²] 2 ], mol.wt ■ act. Komp. = Molecular weight of the metal-based catalytically active component in [g / mol], mol.wt ■ Precursor ~ Molecular weight of the organometallic compound, which serves in particular as a precursor, from which the metal-based catalytically active component is obtained, in [g / mol],
[0113] Pwt = amount of solution of the organometallic compound used, in particular as a precursor, from which the metal-based catalytically active component is obtained, in [g / m³] 2 ], P% = weight percent fraction of the metal-organic compound, which serves in particular as a precursor and from which the metal-based catalytically active component is obtained, in the solution used.
[0114] The advantage here is that the quantity used (P) w t) the metal-organic compound, which serves in particular as a precursor, from which the metal-based catalytically active component is obtained, preferably in a range of 30 g / m³ 2 up to 200 g / m² 2 , especially 40 g / m² 2 up to 150 g / m² 2 , preferably 45 g / m² 2 up to 130 g / m² 2 , especially preferably 50 g / m² 2 up to 100 g / m² 2 , lies.
[0115] It is also advantageous if the weight percent fraction (P%) of the metal-organic compound, which serves in particular as a precursor and from which the metal-based catalytically active component is obtained, in the solution used is preferably in the range of 10 wt.% to 50 wt.%, in particular 13 wt.% to 40 wt.%, preferably 15 wt.% to 37 wt.%, and particularly preferably 18 wt.% to 33 wt.%.
[0116] Furthermore, within the scope of the invention, it is preferred if the amount of the metal-based catalytically active component, based on the textile reactive layer, is 0.01 wt.% to 20 wt.%, in particular 0.1 wt.% to 15 wt.%, preferably 0.5 wt.% to 12 wt.%, and particularly preferably 1 wt.% to 9 wt.%.
[0117] Within the scope of the present invention, effective protective materials with enhanced protective function are obtained using comparatively small application quantities of the catalytically active component. The application and processing method of the precursor compound is also material-efficient. This further underscores the efficiency of the catalytically active components used with regard to the deactivation or neutralization of harmful or toxic substances, as required by the present invention. In this respect, the present invention advantageously allows for the provision of a functionally optimized protective material while simultaneously maintaining a comparatively high level of wearing comfort for protective clothing based on the protective material according to the invention.Regarding the functionality of the protective material according to the invention, good results are also obtained if the metal-based catalytically active component, which is formed and / or present in the form of a porous solid, has a specific BET surface area in the range of 25 m. 2 / g up to 2,000 m 2 / g, especially 50 m 2 / g up to 1,500 m 2 / g, preferably 75 m 2 / g up to 1,250 m 2 / g, especially preferred 100 m 2 / g up to 1,100 m 2 / g, exhibits.
[0118] The BET surface is specifically defined according to DIN ISO 9277 in its current version.
[0119] The determination of the specific surface area according to BET is generally known to those skilled in the art, so no further details need to be elaborated upon. All BET surface area specifications refer to the determination according to DIN ISO 9277. Within the scope of the present invention, the so-called MultiPoint BET determination method (MP-BET) is used to determine the BET surface area – generally and unless expressly stated otherwise – in a partial pressure range p / po of 0.05 to 0.1.
[0120] As already mentioned, the present invention advantageously allows for the application of a coating or impregnation of a catalytically active component to a textile substrate in such a way that particularly large surface areas of the catalytically active compound, which is present in particular in the form of a porous solid or preferably in the form of a xerogel, are achieved. On this basis, increased efficiency with regard to the deactivation or neutralization of pollutants or toxins can be achieved. Due to the large surface area of the porous solid or xerogel, a large catalytically active area can be provided on a comparatively small substrate area, so that a pollutant or toxin reliably comes into contact with the surface of the catalytically active component when flowing through the reactive layer and is thereby deactivated.At the same time, the large surface area allows for a long-lasting effect of the reactive layer, as a comparatively large number of catalytic centers are available.
[0121] Furthermore, it has proven advantageous if the metal-based catalytically active component, which is formed and / or present in the form of a porous solid, is in particulate form and / or in the form of particles. In this case, it is preferred if the particles have a particle diameter, in particular a mean particle diameter D50, in the range of 50 nm to 750 nm, preferably 150 nm to 650 nm, more preferably 200 nm to 550 nm, and most preferably 250 nm to 450 nm.
[0122] The determination is carried out in particular according to DIN ISO 9276-2 in its current version.
[0123] The relevant particle sizes can be determined, in particular, using the method according to DIN ISO 9276-2. Furthermore, the aforementioned quantities can be determined using methods based on sieve analysis, X-ray diffraction, laser diffractometry, or similar techniques. These respective methods are well known to those skilled in the art, so no further explanation is required.
[0124] By forming the catalytically active component in particulate form, good mobility or movement of the reactive layer can be advantageously ensured without the risk of damage to the active material from movements of the textile substrate.
[0125] Furthermore, it has proven advantageous if the metal-based catalytically active component, which is formed and / or present in the form of a porous solid, has a porosity in the range of 10% to 60%, preferably 15% to 50%, preferably 20% to 45%, and particularly preferably 23% to 40%.
[0126] The porosity is preferably determined according to DIN ISO 15901-1 in its current version.
[0127] The determination of porosity is generally known to those skilled in the art, so no further details need to be elaborated upon. In this case, the determination is carried out in accordance with DIN ISO 15901-1, "Evaluation of the pore size distribution and porosity of solids by mercury porosimetry and gas adsorption".
[0128] A porosity in the aforementioned area has proven advantageous with regard to providing an enhanced and reliable protective function of the protective material according to the invention, particularly with regard to effective flow through the catalytically active material. As for the reactive layer itself, it can generally be designed in a variety of ways.
[0129] Within the scope of the invention, it has proven advantageous if the textile reactive layer is a woven, knitted, crocheted, laid, textile composite, nonwoven or non-woven fabric and / or wherein the textile reactive layer is a textile fabric with a basis weight of 10 to 150 g / m², in particular 40 to
[0130] 2 2
[0131] 120 g / m², preferably 60 to 120 g / m².
[0132] Textile carriers with the aforementioned properties and basis weight contribute advantageously overall to increased wearing comfort for protective clothing based on the protective material according to the invention.
[0133] Furthermore, it is preferred if the reactive layer is a textile fabric consisting of, in particular, protic and / or polar and / or hydrofunctional natural and / or synthetic fibers, preferably natural fibers, and / or wherein the reactive layer is a textile fabric consisting of, in particular, protic and / or polar and / or hydrofunctional natural and / or synthetic fibers, preferably natural fibers.
[0134] In this context, it has proven advantageous if the natural and / or synthetic fibers, particularly protic and / or polar and / or hydrofunctional, are selected from the group consisting of cotton; wool; linen; polyesters; polyolefins; polyvinyl chloride; polyvinylidene chloride; acetates, in particular cellulose acetates; triacetates, in particular cellulose triacetates; aramids, in particular meta- and / or para-amides; optionally modified and / or regenerated celluloses; polyacrylic; polyamide; polyvinyl alcohol; polyurethanes; polyvinyl esters; modified and / or regenerated celluloses, in particular viscose; and their mixtures or combinations, preferably cotton.
[0135] In particular, fibers of the aforementioned type allow for a durable and resilient bond or connection with the catalytically active component. Without committing to or limiting ourselves to this theory, it appears that the catalytically active component, especially during the sol-gel process during application, forms chemical bonds with polar groups, such as hydroxyl groups, of the textile substrate fibers, resulting in a strong composite that advantageously leads to high coating durability. In this way, highly effective reactive layers can be produced.Regarding the manner in which the reactive material and the metal-based catalytically active component interact, it is preferred according to the invention if the metal-based catalytically active component is permanently applied, incorporated and / or integrated onto and / or into the textile fabric, in particular onto and / or into the fibers, threads, yarns, filaments or the like forming the fabric, in particular by impregnation processes, chemical treatment processes, in particular reactive coating processes, preferably by application and / or impregnation of a sol, in particular a nanosol, and / or lyogel, preferably a sol, in particular a nanosol, optionally with subsequent aging, in particular condensation and / or crosslinking to form the lyogel, and with drying to form the xerogel.
[0136] For the reactive layer, it is particularly preferred within the scope of the invention if this textile reactive layer, which is present and / or formed as a preferably gas-permeable, textile surface structure, is a woven fabric, knitted fabric, nonwoven fabric, textile composite, fleece or non-woven fabric, and / or wherein the textile reactive layer is a textile surface structure with a basis weight of 10
[0137] 2 2 2 to 150 g / m², in particular 40 to 120 g / m², preferably 60 to 120 g / m², is, in particular wherein the textile reactive layer, which is present and / or formed as a preferably gas-permeable, textile fabric, is a textile fabric consisting of, in particular, protic and / or polar and / or hydrofunctional natural and / or synthetic fibers, preferably natural fibers, and / or wherein the reactive layer is a textile fabric with or made of, in particular, protic and / or polar and / or hydrofunctional natural and / or synthetic fibers, preferably natural fibers, and wherein the metal-based catalytically active component, which is preferably (only) on one side, particularly preferably (only) on the inside of the textile reactive layer, and is present and / or formed in the form of a porous solid, preferably with a net-like structure, particularly preferably as a xerogel, comprises a metal-containing oxide and / or hydroxide,in particular consisting of this, preferably a metal oxide and / or hydroxide, in particular wherein the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide, contains at least one metal selected from the group consisting of Si, Ti, Zr, Cu, Ag, Au, Zn, Ni, Pd, Pt, Rh, in particular selected from the group consisting of Si, Ti, Zr, Ag, Pd, Pt, preferably selected from the group consisting of Si, Ti, Zr, particularly preferably Zr, preferably wherein the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide, comprises one to six, in particular two to five, preferably two to four, oxygen atoms per metal atom, and / or in particular wherein the metal-based catalytically active component, in particular the metal-containing oxide and / or hydroxide, preferably the metal oxide and / or hydroxide,resulting from a sol-gel process and / or, in particular, wherein the metal-based catalytically active component is permanently applied, incorporated, and / or integrated onto and / or into the textile fabric, especially onto and / or into the fibers, threads, yarns, filaments, or the like forming the fabric, particularly by impregnation processes, chemical treatment processes, particularly reactive coating processes, preferably by application and / or impregnation of a sol, in particular a nanosol, and / or lyogel, preferably a sol, in particular a nanosol, optionally with subsequent aging, in particular condensation and / or crosslinking to form a lyogel, and with drying to form a xerogel, preferably wherein the amount of the metal-based catalytically active component, based on the textile reactive layer, is 0.01 wt.% to 20 wt.%, in particular 0.1 wt.% to 15 wt.%, preferably 0.5 wt.% to 12 wt.%, particularly preferably 1 wt.% to 9 wt.%.amounts.,
[0138] For this preferred design of the reactive layer, the aforementioned advantages and technical features are realized to a particularly high degree.
[0139] In addition to the reactive layer, the protective material according to the invention has an adsorption layer. The adsorption layer comprises a particulate adsorbent, or a particulate adsorbent forms this layer.
[0140] Within the scope of the invention, it is preferred if the particulate adsorbent encompassed in and / or forming the adsorption layer, in particular the plurality of individual adsorbent particles, is selected from the group of
[0141] (i) Activated carbon, in particular particulate activated carbon and / or activated carbon particles, preferably in the form of activated carbon particles in granular form (“granular carbon”) or spherical form (“spherical carbon”);
[0142] (ii) Zeolites, in particular natural and / or synthetic zeolites;
[0143] (iii) Molecular sieves, in particular zeolitic molecular sieves, synthetic molecular sieves and / or in particular synthetic molecular sieves based on carbon, oxides and / or glasses; (iv) Metal oxide and / or metal particles;
[0144] (v) ion exchange resins, in particular polydisperse and / or monodisperse cation and / or anion exchangers, especially of the gel type and / or macroporous type;
[0145] (vi) inorganic oxides, in particular silicon dioxides, silica gels and / or aluminium oxides;
[0146] (vii) porous organic polymers and / or porous organic-inorganic hybrid polymers and / or metal-organic framework materials, in particular MOFs (Metal Organic Framework), COFs (Covalent Organic Framework), ZI Fs (Zeolite Imidazolate Framework), POMs (Polymer Organic Material) and / or OFCs;
[0147] (viii) mineral granules;
[0148] (ix) Clathrats; as well as
[0149] (x) their mixtures and / or combinations.
[0150] It is particularly preferred if the particulate adsorbent contained in and / or forming the adsorption layer, in particular the plurality of individual adsorbent particles, is selected from the group consisting of (i) activated carbon, in particular particulate activated carbon and / or activated carbon particles, preferably in the form of activated carbon particles in granular form ("granular carbon") or spherical form ("spherical carbon").
[0151] For these particulate adsorbents, in combination with the previously described catalytically active component of the reactive layer, it has been shown that an advantageous increase in the protective function of a protective material can be achieved. In particular, an advantageous combination of mechanisms of action results, such that effective and, in particular, comprehensive deactivation or adsorption of harmful or toxic substances is achieved. This allows for an increase in the protective effect of protective clothing based on the protective material according to the invention, so that a high level of safety for the wearer of such protective clothing can be ensured. The combined effect of catalytically and adsorptively active materials means, in particular, that harmful or toxic substances are rendered harmless in two ways, so that the probability of penetration is significantly lower compared to conventional protective materials.The concentration of these substances is significantly reduced. Simultaneously, the capacity for neutralizing pollutants and toxins is increased. This increase in capacity is significantly enhanced and long-lasting due to the combination of the catalytic mechanism of action of the catalytically active component and the generally high adsorption capacity of the particulate adsorbent. Thus, a protective material is provided that can effectively withstand particularly high concentrations of pollutants and toxins and also offers long-lasting protection against them.
[0152] Furthermore, it has proven advantageous if the adsorber particles of the adsorption layer are activated carbon particles, preferably in the form of activated carbon particles in granular form ("granular carbon") or activated carbon particles in spherical form ("spherical carbon"), preferably in the form of activated carbon particles in spherical form.

[0364] Further embodiments, modifications, variations, special features and advantages of the present invention are readily apparent and achievable for the person skilled in the art when reading the description, without leaving the scope of the present invention.
[0365] The present invention is illustrated by the following exemplary embodiments, which, however, are in no way intended to limit the present invention. EXAMPLES OF EMBODIMENT:
[0366] The protective function of a protective material according to the invention against harmful or toxic substances, in particular chemical warfare agents, is characterized and determined.
[0367] For this purpose, a reactive layer according to the invention (see, for example, Figs. 1 and 3, reference numeral no. 3, and the preceding description) is first produced according to the inventive method.
[0368] 1. Production of a Xeroqel impregnation on the textile material to produce the reactive layer
[0369] According to the inventive method or, in particular, a preferred embodiment thereof, a sol of the metal-based catalytically active component or of a corresponding precursor thereof is first produced.
[0370] The following chemicals are used:
[0371] • Precursor: Zirconium (IV) propoxide > 70% (w / w) from Thermo Scientific (CAS No. 23519-77-9);
[0372] • Solvent: 1-Propanol > 99%, 99.9%, anhydrous from Thermo Scientific
[0373] The following approaches are produced:
[0374] • 20 wt% zirconium(IV) propoxide solution in 1-propanol anhydrous;
[0375] • 25 wt% zirconium(IV) propoxide solution in 1-propanol anhydrous;
[0376] • 30 wt% zirconium(IV) propoxide solution in 1-propanol anhydrous
[0377] Following the sol-gel principle, the aforementioned Zr-n-alcoholate is hydrolyzed. For this purpose, the nanosol is first generated by stirring the propanol at room temperature (20 °C) while simultaneously adding the zirconium(IV) propoxide solution. Upon introduction into the solvent, the zirconium(IV) propoxide begins to condense and form a colloidal system through interactions of the hydroxyl groups.
[0378] Thus, a cleaner method is used compared to precipitation synthesis; there is no need to remove further salts that are formed as a byproduct in precipitation syntheses, for example.
[0379] Following nanosol production, and preferably before the lyogel formation from the nanosol is complete, the nanosol is applied to the textile material of the reactive layer 3. Alternatively, the lyogel formation (condensation and aging of the nanosol to form a gel) can be allowed to occur first. However, it is preferred that condensation and aging to form a lyogel take place on the textile substrate.
[0380] In this regard, further investigations have been carried out to determine the mass of applied or impregnated coating required to provide sufficient protection from the material while minimizing any impact on the textile properties.
[0381] The amount of coating can be determined as follows: where:
[0382] Cwt = coating amount of the metal-based catalytically active component in [g / m²] 2], mol.wt ■ act. Komp. ~ Molecular weight of the metal-based catalytically active component in [g / mol], mol.wt ■ Precursor ~ Molecular weight of the organometallic compound, which serves in particular as a precursor, from which the metal-based catalytically active component is obtained, in [g / mol],
[0383] Pwt = amount of solution of the organometallic compound used, in particular as a precursor, from which the metal-based catalytically active component is obtained, in [g / m³] 2 ],
[0384] P% = weight percent fraction of the metal-organic compound, which serves in particular as a precursor and from which the metal-based catalytically active component is obtained, in the solution used.
[0385] The resulting coating amount of zirconium hydroxide is thus determined by the amount of precursor compound applied and the concentration of the precursor.
[0386] The applied amount of precursor P w The absorption capacity (t) depends on the capacity of the carrier material used. Since complete saturation of the carrier is preferably avoided (so that only one side of the reactive material is coated), the absorption capacity is limited depending on the carrier material. The maximum amount of precursor found on the carrier material used here is between 60 and 65 g / m². 2 The following assumptions are made: Cotton has a water retention capacity of approximately 50% and the fabric weight is 115 g / m². 2 up to 120 g / m² 2 would be 60 g / m² 2 Saturate the material with water. Due to the density difference between water and propanol, saturation with propanol is achieved at approximately 70 g / m³. 2 to be expected.
[0387] The usable precursor concentration is limited by the processing capability and hydrolysis rate of the sol and is determined experimentally. Three reactions are prepared for this purpose (see the table below). This is based on the calculation of the coating mass for zirconium hydroxide after hydrolysis, as described above, according to the general reaction mechanism for sol formation processes.
[0388] The presence of additional reactive groups from the textile material of the reactive layer allows for the formation of a bond between the metal hydroxide and the textile surface during the sol-gel process, particularly during the condensation and aging of the applied sol to form a lyogel. Therefore, the use of additional binders is unnecessary. For this purpose, the textile material is applied in samples with an area of 0.125 m². 2The material is prepared and pre-dried for 1 hour at 120 °C in a drying oven. To achieve a homogeneous, one-sided coating with good fiber penetration, the Nanosol is applied to the material blanks prepared as described above using a fine spraying process. The coating weight is determined during application. This is based on the selected coating mass P. w t of 65 g / m² 2 The samples are loaded with 8 g of the precursor each. Spray application prevents overloading of the carrier. This effectively avoids quasi-bonding, so-called bridging effects between the fibers. The textile properties of the fabric are therefore not negatively affected. Polycondensation of the nanogel occurs after application of the nanosol, as does drying to form the xerogel at 130 °C in a drying oven for 30 minutes each.
[0389] This process yields a reactive layer according to the present invention (xerogel impregnation in the form of a porous solid with a network-like structure essentially on only one material / surface side). 2. Testing the protective function of the reactive layer by evaluating the degradation of DMMP (dimethyl methylphosphonate).
[0390] To determine the degradation rate of the chemical warfare agent surrogate DMMP (dimethyl methylphosphonate) by the reactive layer, the surrogate is introduced into a sample of the reactive layer under steady-state conditions. In a closed chamber, the degradation reaction is initiated under defined reaction conditions in the presence of the reactive layer sample. Subsequent extraction of the reactants and products of the DMMP degradation process (primarily methanol) allows the conversion of the surrogate to be determined by gas chromatography with an attached flame ionization detector (GC-FID).
[0391] In the experiments conducted, a uniform 47 cm was used. 2 Sample material from the reactive layer is weighed in and the resulting sample mass is determined to ensure comparability of the mass-dependent sample differences.
[0392] The prepared material samples of the reactive layer are each loaded into a headspace vial with 10 pl DMMP dissolved in 1000 pl tetrahydrofuran (THF). The samples are thoroughly wetted. After evaporation of the THF, the samples are left in a drying oven at 30 °C for 16 hours. The samples are then processed with 2 ml of dichloromethane by shaking at 30 °C for 30 minutes, thereby dissolving any organic substances present.
[0393] The extract obtained from this process is analyzed using GC-FID, and the remaining absolute amount of DMMP is determined. The qualitative detection of methanol in the extract allows conclusions to be drawn about whether a DMMP degradation reaction has occurred. For each analysis of the extracted extract, a control sample is analyzed, and the DMMP recovery is determined. This recovery must be > 97% and is used to determine the conversion.
[0394] The degradation rate in % is calculated according to the following formula:
[0395] Degradation rate X = 100 where: c Anfan is the determined quantity from the analysis of the zero sample and is given in mmol. cThe final result is the amount of DMMP determined after a 16-hour reaction time of the sample and is given in mmol. A total of 8 samples of the reactive material according to the present invention are examined according to the described procedure. DMMP degradation rates in the range of 41.0% to 59.3% are determined for these samples.
[0396] The results obtained show that the reactive material exhibits high catalytic activity. Based on the reactive layer or the metal-based coating of the reactive layer, reliable inactivation of the chemical warfare agent substitute can be achieved for all sample sections examined. This functionality of the reactive layer can effectively increase or enhance the achievable protective function in a protective material.
[0397] Comparative reactive material
[0398] A non-inventive comparative reactive material is produced which, instead of impregnation or coating with a porous solid (xerogel), has a coating with Zr(OH)4 obtained from a precipitation synthesis (i.e., by means of precipitation): To produce the comparative reactive material, a textile material, as previously described for the reaction layer according to the invention, is sprayed with a Zr(OH)4-containing salt solution, the hydroxide being obtained from a precipitation process. The weight fraction in the solution used and the amount of Zr(OH)4 applied correspond to the aforementioned values for the example according to the invention. The correspondingly determined DMMP degradation rates are only 29% to 35%.
[0399] This shows that a reactive material produced in a non-inventive manner has lower catalytic activity than the reactive material produced according to the invention.
[0400] 3. Production of a protective material according to the invention using the produced reactive layer and two comparison materials
[0401] The textile material of the reactive layer obtained as described above is further processed by lamination or sewing to create the protective material according to the invention.
[0402] A preferred multilayer protective material according to the invention is produced (i.e., protective material 1, in particular according to Fig. 3, wherein the adsorption layer 4 and the adhesive layer 8 are designed according to Fig. 2B), wherein the multilayer protective material according to Fig. 3 has the following layers with reference numerals 2, 3, 4, 5, 6, 7 and 8, in the sequence listed below:
[0403] (a) optionally a textile outer layer (top layer) 2, wherein the textile outer layer 2 is a gas-permeable textile surface structure,
[0404] (b) a textile reactive layer 3, in particular a textile reactive layer 3 arranged on the inside 2a of the textile outer layer 2, wherein the textile reactive layer 3 is a gas-permeable textile sheet and is coated or, in particular, impregnated with the metal-based catalytically active component only on the outside 3b of the textile reactive layer 3, wherein the metal-based catalytically active component is in the form of a porous solid, specifically as a xerogel,
[0405] (c) a discontinuously formed and gas-permeable adsorption layer arranged on the inner side 3a of the reactive layer 3, the adsorption layer comprising a plurality of individual adsorber particles 4c,
[0406] (d) an inner layer 5 arranged on the inside 4a of the adsorption layer, wherein the inner layer 5 is designed as a gas-permeable textile surface structure,
[0407] (e) a particle and aerosol filter layer 6 arranged on the adsorption layer, wherein the particle and / or aerosol filter layer 6 is a gas-permeable textile fabric comprising a plurality of individual textile fibers, (f) a cover layer 7 arranged on the particle and aerosol filter layer 6, wherein the cover layer 7 is a gas-permeable textile fabric and / or is formed, wherein the particle and / or aerosol filter layer 6 and the cover layer 7 are arranged in particular directly adjacent to one another, wherein the particle and / or aerosol filter layer 6 is arranged on the inner side 3a of the reactive layer 3 and / or the cover layer 7 is arranged on the outer side 4b of the adsorption layer,
[0408] (g) an adhesive layer 8 applied to the side of the outer surface 5b of the inner layer 5 adjacent to the adsorption layer, wherein the adhesive layer 8 is a water vapor and / or gas permeable and discontinuously formed adhesive layer based on an adhesive polymer.
[0409] The adsorption filter material is therefore multi-layered and, viewed from the inside out (i.e., from the support to the outside), comprises a textile inner layer (reference numeral 5 according to Fig. 3) to which a multitude of adhesive (polymer) dots (reference numeral 8 according to Fig. 3) are applied, distributed across the textile inner layer in a grid pattern. Discrete adsorber particles (reference numeral 4c according to Fig. 2B) in the form of activated carbon spheres are permanently fixed or bonded to these, forming the adsorption layer (reference numeral 4 according to Fig. 2B). A textile cover layer and a textile particle and aerosol filter layer (reference numerals 6 & 7 according to Fig. 3) are applied or fixed (i.e., by lamination) to the activated carbon spheres or the adsorption layer to further enhance the protective function against pollutants and toxins.This is followed by the reactive layer coated with the xerogel-forming, metal-based, catalytically active component, here in the form of Zr(OH)4 (see previous manufacturing example). The impregnation is located on the side of the reactive layer facing a potential source of pollutants (reference numeral 3b, Fig. 1). Finally, the protective material comprises an outer textile layer (reference numeral 2, Fig. 3).
[0410] This results in a multi-layered, air-permeable protective material (i.e.,
[0411] Protective material 1 (as shown in Fig. 3) in the form of a laminate. Specifically, the following materials were used:
[0412] • Inner layer 5: knitted textile fabric, basis weight approx. 80 g / m² 2 (determined according to DIN EN 12127 after 24 hours of air conditioning at a temperature of 20 °C and a relative humidity of 65 %);
[0413] • Adhesive (polymer) or bonding agent layer 8: Polyurethane (PU), application rate approx. 35 g / m² 2 , surface of inner layer 5 covered with adhesive (polymer) to less than 40%;

[0415] • Particle and aerosol filter layer 6: gas-permeable textile surface structure (non-woven) made of numerous individual synthetic textile fibers with fiber diameters in the range of 50 nm to 10 pm, basis weight of approx. 50 g / m² 2 (determined according to DIN EN 12127 after 24 hours of air conditioning at a temperature of 20 °C and a relative humidity of 65 %);
[0416] • Outer layer 2: gas-permeable, textile fabric in the form of a woven material, basis weight approx. 140 g / m² 2 (determined according to DIN EN 12127 after 24 hours of air conditioning at a temperature of 20 °C and a relative humidity of 65%), oleophobic and hydrophobic treatment by impregnation or coating using a fluorinated polymer;
[0417] • Textile material of reactive layer 3 (if present, see comparative example 1): gas-permeable textile fabric made of fibers with a composition of 88 / 12% cotton (Nm 170 / 1 US Pima long staple, Z-wire) / elastane (22 dtex, monofilament), weave: single jersey, smooth R / L, elastane plated, pitch: E50, basis weight (determined according to DIN EN 12 127: 1997): 115 + / - 10 g / m² 2 .
[0418] This protective material according to the invention is hereinafter also referred to as "protective material 1 according to the invention". Furthermore, another protective material according to the invention ("protective material 2 according to the invention") is produced, wherein the further protective material according to the invention ("protective material 2 according to the invention") differs from the protective material 1 according to the invention only in that it does not have a particle and aerosol filter layer according to reference 6.
[0419] In addition to the protective materials according to the invention, two comparison materials are also provided, as described below:
[0420] Provision of comparison materials 1 and 2 (= comparison examples 1 and 2): Two material structures serve as comparison examples, which differ from the protective material according to the invention as follows:
[0421] Comparison example 1 (= comparison material 1 ):
[0422] Layer structure as previously described for the material according to the invention, however without the reactive layer (= reference numeral no. 3).
[0423] Comparison example 2 (= comparison material 2):
[0424] Layer structure, as previously described for the material according to the invention, but with a different type of reactive layer, which in the case of Comparative Example 2, instead of an impregnation or coating with a porous solid (xerogel), comprises a coating with Zr(OH)4 obtained from a precipitation synthesis (i.e., by means of precipitation): To produce the reactive layer of Comparative Example 2, a textile material, as previously described for the reaction layer according to the invention, is sprayed with a Zr(OH)4-containing salt solution. The hydroxide is obtained from a precipitation process. The weight fraction in the solution used and the amount of Zr(OH)4 applied correspond to the aforementioned values for the example according to the invention.
[0425] The comparison materials in comparison examples 1 and 2 were also produced by laminating or sewing according to the aforementioned layer structure specifications.
[0426] The three material samples obtained (i.e., the protective material according to the invention and comparison materials 1 and 2) are subsequently examined comparatively with regard to the quality and quantity of their protective function against chemical warfare agents. 4. Testing the protective function of the protective materials according to the invention and the two comparison materials
[0427] The protective function of the previously produced protective materials according to the invention, as well as of the two previously produced comparison materials, is subsequently tested.
[0428] Protective function against harmful or toxic substances, in particular chemical warfare agents, based on method 2.2 of CRDEC-SP-84010 and with regard to the warfare agent Bis[2-chloroethyl1sulfide (= mustard gas or HD)
[0429] First, the protective function of the previously produced protective materials according to the invention, as well as the two previously produced comparison materials, against harmful or toxic substances, in particular chemical warfare agents, is characterized and determined on the basis of method 2.2 of CRDEC-SP-84010 and with regard to the warfare agent bis[2-chloroethyl]sulfide (= mustard gas or HD).
[0430] This method is used to determine the barrier effect of a protective material against mustard gas, whereby the quality of the protective function or the quality of the barrier effect increases with decreasing breakthrough values.
[0431] According to the applicant's specifications, the barrier effect against mustard gas, determined according to method 2.2 of CRDEC-SP-84010, should be less than 4 pg / cm². 2 per 24 hours.
[0432] In particular, this determination method involves a so-called convective flow test with mustard gas; for this purpose, an airflow containing mustard gas is directed onto the test material at a constant flow resistance and a flow velocity of approximately 0.45 cm / s, and the area-related breakthrough quantity is determined after 24 hours (10 • 1 pl HD / 12.56 cm²). 2 , 80% relative humidity; 32°C).
[0433] Testing a reference sample
[0434] As a non-inventive reference, the barrier effect against mustard gas is first determined on a sample (10 cm x 10 cm) of a multilayer protective material, but without an adsorption layer and without a reactive layer, according to method 2.2 of CRDEC-SP-84010:
[0435] > 10 pg / cm 2Tests on the inventive protective material 1 and on the two comparison materials 1 and 2 every 24 hours (i.e., outside the applicant's specifications)
[0436] Likewise, corresponding test pieces of the protective material according to the invention, produced as described above, as well as the two comparison examples, are determined with regard to the barrier effect against mustard gas according to method 2.2 of CRDEC-SP-84010:
[0437] • Protective material according to the invention: < 0.08 pg / cm² 2 per 24 hours
[0438] • Comparison material 1 : 1 ,81 pg / cm² 2 per 24 hours
[0439] • Comparison material 2: 1.42 pg / cm² 2 per 24 hours
[0440] Testing on another inventive protective material 2
[0441] Likewise, a corresponding test piece of another protective material according to the invention is determined with regard to its barrier effect against mustard gas according to method 2.2 of CRDEC-SP-84010 (whereby the further protective material 2 according to the invention differs from the protective material 1 according to the invention only in that it does not have a particle and aerosol filter layer according to reference 6):
[0442] Further protective material according to the invention 2: 0.91 pg / cm² 2 per 24 hours
[0443] Further testing of the protective function of the inventive protective materials 1 and 2 and of a comparison material 2
[0444] Furthermore, the protective function of the previously described protective materials 1 and 2 according to the invention, as well as the previously described comparison material 2, is tested against gaseous soman (so-called GD gas test). Soman is the 1,2,2-trimethylpropyl ester of methylfluorophosphonic acid and is a liquid, camphor-like odorous substance under standard conditions, which hydrolyzes in air or under the influence of moisture.
[0445] The textile sample to be tested (each 12.56 cm) 2 ) is clamped in a special test cell and exposed to the chemical warfare agent soman under controlled conditions (temperature in the test cell: 30 °C; relative humidity in the test cell: 80 %; chemical warfare agent concentration of the gas flow: 200 mg / m³). 3 Flow rate: 0.066 cm / s, corresponding to 50 ml / min; Poisoning time: 3 h).
[0446] The transmitted chemical agent, the entrained clean air, and any decomposition products are collected in a gas collection container filled with a suitable solvent (here: diethyl succinate, or DES). The amount of chemical agent transmitted is determined using gas chromatography-fluorescence permeability (GC-FPD). After a test duration of 3 hours, each material sample is removed from the test cell and transferred to a glass container filled with a defined volume of the solvent (DES). The chemical agent remaining in the textile samples is extracted over 8 hours. The amount of chemical agent remaining is then also determined using GC-FPD.
[0447] The protective materials "protective material 1" and "protective material 2" described above are tested as protective materials according to the invention. The previously used "comparative material 2" serves as the reference material.
[0448] In the protective material 1 according to the invention, the amount of chemical warfare agent (soman) remaining or absorbed in the material is reduced by 29% (by weight) compared to the reference material 2, and in the protective material 2 according to the invention, it is reduced by 24% (by weight) compared to the reference material 2.
[0449] It follows that, in the protective materials according to the invention (i.e., "protective material 1" and "protective material 2"), a significant proportion of the chemical warfare agent can be broken down due to the specially designed textile reactive layer with the metal-based catalytically active component in combination with the additional adsorption layer. Thus, the exposure to the chemical warfare agent in the protective materials according to the invention is significantly reduced compared to the reference material 2 with a different reactive finish, accompanied by a significantly improved overall protective performance of the material. In the protective material 1 according to the invention with a particle and aerosol filter layer, the overall performance is further improved compared to the protective material 2 according to the invention without a particle and aerosol filter layer.
[0450] Conclusion
[0451] The above tests show that the reactive layer produced or manufactured according to the invention results in an improved barrier or protective effect of the protective material as a whole against chemical toxins or combat agents.
[0452] The additional presence of a particle and aerosol filter layer, in combination with the reactive layer produced according to the invention and the additional adsorption layer, further enhances the barrier and protective effect of the overall protective material.
