The importance of polymer compositions in the processing of textile raw materials and production is shown. A composite solution of natural and synthetic polymers is impregnated with raw materials in the production of cotton yarn by the spinning method. 2 l of the solution contained 200 ml of 10% collagen solution, 40 ml of 0.5% polyacrylamide solution, 10 ml of glycerol. The polymer composition was sprayed onto raw cotton. If 6.6% of waste is formed in the scutching process of raw cotton, this figure decreases to 3.3% when applying the emulsion. According to the plan developed for emulsified raw materials, the required yarn was obtained on a BD 330 open-end ring spinning machine. Based on the regime developed for emulsified raw materials, yarn was obtained on a BD 330 open-end ring spinning machine. Evaluation of the efficiency of the spinning process was made by the unevenness of the yarn by weight, the number of thin and thick layers, the number of neps. Compared to conventional yarn, the unevenness of the emulsion yarn decreased by 0.56%, thin sections by 39%, thick sections by 26%, and the number of neps by 27,7%. The application of the polymeric composition also improved the mechanical properties of the produced yarn. Tensile strength of threads increases by 3.5 cN, specific tensile strength - by 0.15 cN, relative elongation at break - by 11%, work at break - by 6.5%. A small amount of substances that make up the composition in relation to the mass of cotton yarn, i.e. collagen 0.1%, polyacrylamide 0.02%, glycerol 0.005%, contributes to a noticeable improvement in the spinning process and yarn strength. They do not adversely affect the process of weaving and production. Small amounts of additives do not cause problems in the chemical processing of products.
