The closest analogue to the invention is a multilayer material for internal parts of footwear and apparel products, consisting of a fibrous substrate and facial thermoplastic layer made of a composition based on a polymeric binder, plasticizer and pigment (2).

These multilayer materials have high enough strength, thermocline, which leads to delamination of the internal parts in the manufacture of footwear; the temperature of the processing for bonding to the top of the Shoe is 80-90oC.

The objective of the invention is to increase the strength of thermocline and reducing the temperature of the bonding material.

The technical result is achieved in that in a multi-layer thermoplastic material layer is made of a copolymer of ethylene with vinyl acetate density 0,950 0.005 g/cm3; a melt flow index of 15-40 g/10 min, the mass fractions of vinyl acetate 26-30% plasticizer oil contains paraffin wax with a melting point 52-62oC, as pigment - granular pigment on�,05-0,30):(0,002-0,05) accordingly, when this thermoplastic layer formed at the 100oC 150oC with a gain of 10 to 300 g/m2. Also the fact that the plastic layer further comprises a filler in an amount of 3 to 30 to 100 wt.h. copolymer of ethylene with vinyl acetate, and as the Foundation it contains the fabric. In addition, the fact that it further comprises a back layer made from the composition of the surface layer, while the front and/or back layer is made intermittent or monolithic.

The composition of the granular pigment.

The pigment up to 50% of the rest of the polymer binder: low molecular weight polyethylene or a polyethylene wax.

Color: silver grey. Temperature kamlapati the ity of thermocline on the sample of the finished material was determined according to GOST 27319.

The temperature bonding was determined by measuring the surface temperature of the press plates, Feb mercury thermometer.

The formation of thermoplastic layer at a ratio of polymeric binder, plasticizer and granular pigment 1:(0,05-0,30):(0,002-0,05) accordingly leads to a sharp increase in the strength of thermocline and reduce the temperature of the bonding Shoe blanks.

Using the specified granular pigment in the system is a copolymer of ethylene with vinylacetate and paraffin oil is not only painting, but also to improve the adhesion properties of the composition and heat resistance, and impact ultimately on improving the performance of materials made according to the claimed technical solution.
