Abstract

The invention relates to the textile industry, to the processing industry of recycled textile raw materials, and can be used for the production of nonwoven laminates used as flooring and cushioning materials in the manufacture of soft furniture. The invention relates to the textile industry and to the recycling sector of recycled textile raw materials, namely the production of non-woven laminated materials used for the manufacture of gasket materials for the furniture industry, thermal insulation pads in the construction industry, etc. The purpose of the invention is to increase the elasticity of the material and reducing its material consumption. industry and others, and allows for the improvement of the elasticity of the material and the reduction of its material intensity. Non-woven laminated material, bonded with stitching, includes outer layers of textile cloths and an intermediate fibrous canvas consisting of 20-60% industrial waste of viscose polo, 30 - 0% mixture of regenerated synthetic fibers from scraps of fabric and knitwear and 10 20% of industrial waste poaiacrylonitrile i-olokon from riaie rial passes. Increasing the elasticity of the proposed non-woven laminated material while simultaneously; its material consumption is achieved by using a mixture of regenerated synthetic fibers (polyamide, polyester) and industrial waste of viscose and polyacrylontril fibers uniformly distributed among them. The goal is achieved by the fact that non-woven laminated material, including externally an elephant from textile cloths and an intermediate fibrous canvas from waste synthetic fibers, held together by stitching, in which the intermediate fibrous canvas contains industrial waste of viscose fibers in the amount of 20-60%, and as waste synthetic fibers used a mixture of regenerated vultures (L o oe 4 & O 00

UPG and polpacrylon Rilp fibers contribute to obtaining a more optimal elasticity and, accordingly, subtlety to crushability of the proposed material, which predetermines {a longer service life.

In addition, the presence of such a composition of the fiber components will make it possible to reduce the surface density (material consumption) of a material at the same thickness as compared with the known material.

The limits of the percentage content of various types of recycled textile raw materials in the composition of the proposed composition of the intermediate fiber-canvas and non-woven laminate material are optimal.

The invention is illustrated by examples.
