Abstract.
The article discusses the use of non-recyclable fibrous waste of natural silk into textile 
products of wide consumption, in particular, in the production of non-woven materials, with the 
subsequent receipt of goods of consumer goods. For the production of materials used primary 
and secondary silk fibers in a mixture of chemical fibers. Non-woven material was obtained by 
thermopressive method. Analysis of the experimental data showed high physicomechanical 
properties of materials from the primary and secondary fibers. The presence of natural silk 
fibers in the mixture leads to the formation of adhesive crying, which further increases the 
strength of non-woven materials, the physicomechanical and mechanical studies have shown 
that the partial replacement of chemical fibers for natural silk waste allows noticeably to 
increase the physicomechanical properties of non-woven materials based on them.

Introduction. 
The use of secondary raw materials in all developed countries is paying 
much attention, while it is important to use waste at the level of full raw materials. Waste textile 
fibers available at different stages of production are a valuable secondary raw material that can 
be rationally used. The rational use of waste of polymeric materials is the most important task 
both in terms of the expansion of resources and environmental protection. 
In recent years, the processing of chemical and synthetic fibrous materials has increased 
significantly in the textile industry. Simultaneous with this, new machines for processing waste 
textile production appeared. New techniques and technology of extrusion of polyolefin materials 
directly in textile enterprises lead to the expansion of the range of textile raw materials, such as 
waste of staple fibers, yarn, chemical threads, trimming of harsh tissue, knitwear and knitted 
products, nonwovens, various layered materials, as well as waste, formed on extrusive 
installations. 
In the textile industry, certain activities are held on the use of secondary material 
resources, however, the level of use of important types of waste is currently not recognized as 
satisfactory. Currently, in the industry of chemical fibers, especially in the production of viscose 
fibers, a significant amount of waste is formed, most of which are technically scheduled. In 
addition, as a result of the deterioration of any of the production parameters, substandard 
products are formed, the quality of which in some cases cannot be brought to the level of 
requirements of technical conditions. High strength Stability properties When heated and an 
increased initial module of viscose fibers make it possible to consider it processing it as a filler 
for composite materials and rubber products./1-4/
