Brief description, advantages, further prospects for application.

As a result of the study of the individual and combined effects of light, washing and sweat on the wear resistance of knitted fabrics made from natural fibers, it was found that under operating conditions, the effect of light is decisive in the process of wear of cotton knitted clothing. On the basis of theoretical studies of the regularities of the processes of loss of color, shape and strength of cotton knitwear for summer clothes, it was determined that the final processing using a polymer composition based on a film-forming polymer and light stabilizers is an effective and environmentally friendly way to increase the light, shape stability and strength of cotton. Based on comprehensive studies of the physicochemical properties of knitwear and dyes and the operating conditions of products, technologies have been developed to increase the wear resistance of knitted fabrics made from natural fibers, which ensure the preservation of color, shape and strength. The technology of finishing cotton knitted fabrics by combining the technologies of preparation and use of light stabilizers in the final processing of the polymer composition contributes to an increase in light, shape stability and strength of cotton knitwear.
