A three-layer non-woven composite material for clothing and footwear has been obtained by an adhesive bonding method. The thickest middle layer of the material consists of evenly laid coarse fibers of sheep wool, the top and bottom layers are made of cotton jersey, polymer glue is located between the layers. The layers are bonded by thermal duplication at a temperature of 150 ± 5 ° C for 2.0 ± 0.2 minutes. The structure of the layered material was investigated by FT-IR spectroscopy and scanning electron microscopy. Established chemical and adhesive interaction between fibers of sheep wool, cotton and polymer glue. In the process of thermal exposure, the molten polymer is sorbet, both into the structure of wool and knitted fabric, which leads to a decrease in the density and an increase in the thickness of the adhesive layer. Sorption and excellent adhesion of the molten polymer to the fibers ensures the solidity and strength of the composite material. The strength and thermos physical properties of the layered material have been determined.
