Definitions

  • the invention relates to a waterproof moisture-conducting textile material.
  • the invention has for its object to provide a textile material that is water and possibly also airtight, but at the same time is able to store a considerable amount of moisture initially, but also to transport and in the form of water vapor on both sides again to deliver.
  • a storage effect of clothing is desirable because sweat production is not evenly distributed over time. Therefore, the textile material of the clothing must be able to absorb a short-term excess production of moisture, which cannot be discharged quickly enough, like a "buffer". It is also important that this buffer effect, which has a favorable influence on the wearing comfort, is achieved in connection with the moisture transport in such a way that the mechanical properties of the textile material meet high requirements.
  • this object is achieved by a waterproof moisture-conducting textile material which consists of a water vapor-permeable textile carrier which is sealed with a closed layer of a hydrophilic polymer.
  • the sealing layer is in particular a foam coating, which can also be compressed.
  • foam coating and the subsequent compression are common procedures in textile equipment.
  • Other possibilities are a foam coating with an additional coating, as well as a coating that can be applied as a paste, solution, dispersion or melt.
  • the textile backing can have the structure of a woven or knitted fabric, but also a fleece or a so-called nonwoven material. It can be made from natural fibers such as cotton, wool or silk as well as synthetic fibers based on polyesters, polyamides, polyacrylonitrile, polyurethanes, polyolefins, polyvinyl chloride, aramids or even mineral fibers such as glass fibers or carbon fibers. It is not important whether the textile backing itself is hydrophobic or hydrophilic, but what matters most is that it is permeable to water vapor. In the case of a very dense, only slightly air-permeable textile fabric, the own hydrophilicity of the fibers can also contribute, while a hydrophobic textile carrier should be sufficiently open to be sufficiently permeable to water vapor in this way.
  • the water vapor-permeable textile carrier is sealed by applying a closed layer of a hydrophilic polymer.
  • Suitable hydrophilic polymers are known or can be prepared or mixed together by the textile chemist from conventional components. In any case, the property of absorbing water vapor at places with high partial pressure, a migration of the water molecules in the layer to places with a lower partial pressure and the release on the surface in the form of water vapor is possible because sufficient hydrophilic groups are present in the closed layer , in particular hydroxyl ether amine or carboxyl groups are contained.
  • hydrophilic groups can be produced with hydrophilic monomers due to the copolymerization or co-condensation of monomers which cause chain formation or crosslinking, or polymers with a very high water absorption capacity are processed together with polymers which have other desired properties, but not or only very little are hydrophilic.
  • Monomers with hydrophilic groups are, for example, hydroxyalkyl acrylates or the acrylic and methacrylic acid esters of polyalkylene oxides or polyalkyleneimides. Such acrylic or methacrylic acid derivatives can then be copolymerized with the acrylic or methacrylic acid esters forming the base polymer and crosslinkable monomers. Dispersions of such hydrophilic resins are known for example from DE-OS 27 49 386.
  • the commercial product Plextol 4871D from Röhm GmbH is also suitable for a sealing moisture-conducting coating, but also modified vinyl alcohol resins or cellulose regenerates.
  • copolymers of vinyl chloride and vinyl acetate in which the acetate groups have been hydrolyzed to OH groups or polyurethanes with an excess of OH or NH and NH 2 groups.
  • hydrophilic monomers can be copolymerized, it is also possible to blend dispersions made from them with dispersions whose properties are desired for other reasons.
  • polyurethanes have very good mechanical properties and polyvinyl chloride improves flame retardancy.
  • a polyvinyl chloride with built-in monomers with strongly hydrophilic groups can also be used, for example.
  • the desired properties can also be obtained by using starting materials which have sufficient hydrophilic groups, in particular ether or imine groups.
  • Test trials can easily determine whether a coating meets the requirements of the invention with regard to moisture absorption and moisture conduction.
  • the coatings according to the invention should expediently be able to store 200 to 400% of their weight in moisture and the water vapor permeability should be at least 500 g / 24 hxm 2 according to DIN 53122.
  • the B can eschich- tung also conventional additives such as dyes, adhesion promoters, antioxidants, antistatic agents, pigments, heat stabilizers, fillers, etc. included.
  • the coating is usually applied as a dispersion or as a foam, which can still be compressed subsequently, in an amount of 5 to 500 g / m 2 , calculated as a dry coating. If importance is attached to the fact that the coating is also airtight and accordingly a dense, only slightly air-permeable textile fabric, in particular fabric, is selected as the carrier, then a dry coating over 50 g / m 2 is recommended. For many purposes, in particular in connection with a not very dense and air-permeable fabric as a carrier, a very light coating with the hydrophilic polymer, which is still air-permeable, can also be very useful.
  • These thin coatings can be obtained by scraping them on according to a dry coating of 5 to 50, in particular 10 to 30 g / m 2 . It has been shown, for example, that such a waterproof, still more or less air-permeable, but in any case moisture-conducting textile material is very suitable for permeable, ie breathable ABC protective suits. These usually contain an outer layer and a filter layer underneath, but the gaseous warfare agent does not adequately adsorb liquid. It is therefore one of the functions of the outer layer to keep liquid weaponry away from the filter layer. For this purpose, oleophobic equipment is used, for example.
  • the water vapor-permeable coating is also suitable as a binding member for laminating textile fabrics together, so that a further layer of a water vapor-resistant! permeable textile fabric is applied. In this way, double substances are obtained which, if desired, can be additionally hydrophobicized on the outside.
  • the textile backing can be provided not only on one side but also on both sides with the sealing layer of a hydrophilic polymer.
  • Materials with a specific protective effect e.g. Lead sulfate as radiation protection, activated carbon as protection against warfare agents, antimony trioxide and halogenated aromatic compounds as flame retardant equipment. It is also possible to apply such or other materials with a specific protective effect to the coating.
  • the coating also serves as a binder for these materials with a specific protective effect.
  • an open-pore hydrophobization on the outside of the material which does not impair the water vapor permeability, is recommended when it is used later; this can be both the textile support and the laminated material or the sealing layer.
  • the water repellency has a water-repellent effect only for a short time, since when viewed enlarged it is applied in a punctiform manner or in the form of nests, the water absorption of the sealing layer according to the invention still causes a strong swelling of the coating, which further enhances the sealing effect.
  • This is particularly advantageous in cases where the tightness plays a role, such as the distress rescue suit for pilots.
  • This must be normally portable but also waterproof in an emergency in order to protect pilots who jump over cold water against the ingress of water and thus the risk of hypothermia for a certain period of time.
  • Other examples are protective suits for various areas of application, such as ABC protective suits, protective suits for civil protection or protective suits for (nuclear) power plants.
  • the water vapor permeable coating can act as a barrier against water, dust and gases.
  • the aforementioned water-vapor-permeable double fabrics according to the invention are suitable for high-quality rainwear with good wearing comfort, sleeping bags, sportswear and the like.
  • a cotton twill (1) with a basis weight of 140 g / m 2 was coated with an acrylate foam (2) from Röhm GmbH (test product 6533/15) with a foam weight of 300 g / 1 (Fig. 1).
  • the dry edition was 35 g / m 2 .
  • the water column according to DIN 35886 was more than 100 mm and the water vapor permeability according to DIN 53122 was more than 1000 g / 24 h -m 2 .
  • Example 3 The procedure was as in Example 1, with the difference that the dry coating was 300 g / m 2 and contained 50% by weight of finely powdered lead sulfate (3) (FIG. 3). Such a material is particularly suitable as radiation protection.
  • Example 4 The procedure was as in Example 1, with the difference that the wet acrylate foam (2) was sprinkled with fine-grained activated carbon (4). The coal (4) was then pressed on, then dried and the acrylate foam (2) condensed (FIG. 4).
  • Such a waterproof, moisture-conducting textile material is suitable as a C protection (chemical warfare agents).
  • Example 2 After a coated fabric web (1, 2) had been produced as in Example 1, an acrylate dispersion (7) (dry layer 10 g / m 2 ) was applied to the coated side (6) again and a second fabric web (8) was pressed on (Fig 5). After the condensation was hot calendered. The water vapor permeability was about 1000 g / 24 h. m 2. Such a double fabric is good rain protection or a good material for sportswear, especially after subsequent hydrophobing.
  • a cotton twill was coated according to Example 1, but with the difference that a dispersion of self-crosslinking polyvinyl alcohol, which had been blended with 40% of a dispersion of a soft polyurethane, was used.
  • the water vapor permeability was somewhat lower than in Example 1, but many times higher than in known products.
