BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a bottled insole material, particularly for sports shoes and footwear, consisting of a textile backing layer and a foam backing.

In the production of sports footwear, high demands are also placed on the materials used for the shooting, which I decide! on the overall characteristics of the final product. The bottom layers of stieloks were made of fibrous and damping masses based on natural or synthetic fibers, optionally polymer-bonded. Currently, insole materials are known whereby a combination of textile with a lightweight rubber layer is used. However, the combination of insole material has disadvantageous hygienic properties.

Known is a latch material based on ethylene-vinyl acetate composites or a mixture of this copolymer with polyethylene. The material has a structure of closed pores and low density. Of the other known latch materials, the first is a polyvinyl chloride plastic latch which is shaped to the desired shape by effecting high-frequency heating in compression during compression. The second latch is made of two cuts of polyvinyl chloride foil with a thickness of 0.5 mm, which are welded after. Circuit. The other welds are separated by the peak and outer jewel parts. The sealed common space in the inner vault and fifth portions is filled with glycerin, the peak space is filled with foamed polyvinyl chloride, and the outer vault space is left empty. The third part is made up of three layers, where the middle layer is made of polyurethane, the top layer fabric of TEXON and the bottom layer is made of elastic polyvinyl chloride. Also known are polyolefin damping compositions which are based on natural butbopolyisoprene rubber, zinc white, stearin and other additives.

Said polyolefin composition for application has a low specific gravity and a hardness of 15 to 25 Sh. Another known sheath material is a combination of a fabric with a chemically-coated polyvinyl chloride base layer or a high-strength crosslinking polyolefin. The advantage of these insole materials is that their construction and especially the closure of the pores do not allow good drainage of sweat and water vapor. A further disadvantage is the very low recovery ability due to the impact caused by the impact, the high percentage of permanent deformation during extended wear and the reduction of the hygienic, health and utility properties of the insoles.

The above drawbacks are eliminated by the refractory sheathing material, which is characterized in that the textile facing layer is pointed to a mechanically coated polyvinyl chloride layer comprising 60 to 95% by weight of the plasticizer parts, 2 to 5% by weight. parts of stabilizer and 0.1 to 2 wt. parts of thermostabilizers, related to the weight of polyvinyl chloride, 3 with a density of 100 to 800 kg / m, a hardness of 10 to 30 Sh, a resistance to compression of 30 to 70 kPa, hysteresis of 20 to 40%, permanent deformation to 15% of the total ridge and permeability of 2 water vapor at least 3.5 mg / cm, h. Furthermore, the softened layer of polyvinyl chloride may contain from 0.01 to 3 wt. parts of anti-fungal and antibacterial ingredients and 0.1 to 40 parts by weight of fillers based on the weight of the polyvinyl chloride.

The technical effect of the invention is manifested by the fact that the textile formation which comes into contact with the foot absorbs sweat very intensively and the water vapor, which allows the transport of them by open, interconnected pores of mechanically treated polyvinyl chloride. In retraction of the web material in the walkway, sweat and water vapor are transported, relieving the sorption. In the rhythmic repetition of sorption and subsequent transport for the duration of walking and running, sweat and water vapor are effectively removed. At the same time, open pores allow effective absorption of substances with pronounced antibacterial and antifungal effects. Additive additives will increase the absorption efficiency of antibacterial and antifungal agents. f.Lightened shot material is illustrated in more detail by the following examples of practical embodiments where the amounts of ingredients are given in parts by weight. 3 257458 Example
