(57) Abstract:The invention relates to multi-layer textile fabrics for the manufacture of flexible containers (tanks), tents, canvas, clothing. Canvas with a layer of fabric, one side of which is a rubber layer, and on the other side of a tissue layer film of a synthetic polymer. Film of a synthetic polymer made of polyvinylidene fluoride and is located between two rubber layers. Due to this arrangement of the polymer layer is achieved lasting protection against all kinds of toxic effects of chemical substances and chemicals, increase the elasticity of the textile fabric. 3 Il., table 1. The invention relates to a multilayered textile fabric for the manufacture of flexible containers (tanks), tents, canvas, clothing, etc. with a layer of tissue located on one side of the layer of fabric with a layer of rubber and located on the other side of a tissue layer film of synthetic polymer, which is located between two layers of rubber.From the Federal Republic of Germany patent A 1-3907453 know this kind of textile fabric, in the case in which the quality of a film of synthetic polymer used polyimide layer, to the e l e C commercially available under the name VITON. A layer of VITONmust protect the polyimide layer from UV radiation, in relation to which this material is not very resistant.From European patent A 1-0432492 and WIPO 91/03379 known application of VITONagainst exposure to chemicals and gases.The aim of the invention is the creation of a multi-layered textile fabric that is suitable for the manufacture of flexible containers, tents, canvas, clothing, etc. that protects against chemical warfare agents, but also from other chemicals, and has better properties than known materials. To reach this aim the fact that the film of synthetic polymer comprises polyvinylidene fluoride.As shown by numerous tests, proposed according to the invention the textile fabric, highly durable, and it is not only in mechanical terms, but also practically acting against chemical warfare agents and chemicals. In comparison with a layer of VITONused according to the invention the layer of polyvinylidene fluoride, especially when used against nuclear, bacteriological and chemical impacts is compared with the application of a layer of butyl, makes improvement, but the difference in the application layer of polyvinylidenfluoride greater.Thanks are located on both sides of the PVDF layer rubber layers unexpectedly also increases the elasticity of the textile fabric and along with making it easier to manipulate with it.At the location of the rubber layer on the outer side of the layer of polyvinylidene fluoride is not only particularly important when exposed to chemical warfare agents protection polivinilidenftoridnoe layer, and an additional rubber layer also provides an indicator of the action, as damage to the rubber layer can be installed much easier than damage PVDF layer; damage to the rubber layer can be controlled, suffered does the PVDF layer and whether you need to replace the canvas, clothing, or etc.The invention is illustrated by drawings and examples of implementation, but not limited to these examples, the scope of protection of the invention.In Fig. 1 shows a section of elastic containers for liquid, and Fig. 2 design used for containers according to Fig. 1 laminated textile fabrics; Fig. 3 - schematics is here for liquids or elastic reservoir (tank) for liquid consists of two, United with each other at the edges, laminated textile fabrics 1 and 2. To enhance the binding on the edges are attached amplification of the ribbon 4. Capacity in a known manner provided with holes (not shown), which allow you to fill and pour the liquid, and also to carry out the removal of air.As can be seen from Fig. 2, multi-layer textile fabrics 1 and 2 consist of a layer of fabric 5, in which both sides suffered rubber layer 6. The upper rubber layer 6 (Fig. 2) covered by a layer 7 of polyvinylidene fluoride, which is another rubber layer 6. Located between the two rubber layers layer 7 made of poly (vinylidene fluoride) in the case of containers for transporting contaminated (infected) material is on the inside. In the case of the other purposes of applying this layer 7, including two rubber layer 6 located on the outer side layer of the fabric.As already mentioned, the layer 1 of the polyvinylidene fluoride type film. The rubber layer is applied by a known method for prorezhivanija and separate the layers are linked by vulcanization. You can apply for about 20 min a temperature of about 140 - 175oC and a pressure of about 3 bar.s (system). Multi-layered textile fabric 8 on the sides provided with rings (ears) 9 so that you can strengthen the tarpaulin. Textile fabric 8 is in principle the same structure as textile fabrics 1 and 2.In the framework of the invention may have many changes. Thus, the multilayered textile fabric according to the invention can be applied, for example, for the manufacture of tanks, in which contaminated soil or etc., comes to the place of testing. Of proposed according to the invention laminated textile fabrics can be produced tents; anti-nuclear, anti-bacterial and anti-chemical gateways (overlapping), etc.Depending on the type of load, the weight of one square unit of material varies, and this weight is a value ranging from 350 to 1500 g/m2. Multi-layered textile fabric for manufacturing in particular stretchy tanks, tents, canvas, clothing, containing a layer of fabric, one side of which is a rubber layer, and on the other side of the layer of fabric placed between two rubber layers of the film of a synthetic polymer, wherein the film of a synthetic polymer made of at
