This article deals with the development of a new composition of a polymer composition for dressing cotton yarn. The optimal concentration of the dressing polymer composition, which is 50 g/kg, against the starch-based dressing is 70 g/kg, i.e. the consumption of starch is reduced by 25-30%. It is experimentally established that the concentration of the dressing, which has a significant impact on the cost of the dressing, varies within 45-50 g/kg of the composition, while the true glue remained at the same level. Theoretically, the interaction between the polymer groups and the reactive groups PVA and HIPAN is justified. The products resulting from this interaction contain, in particular, amide -CONH, carbamide - NHCONH, carbamate - ОСОNH2, ester - ОСО and other groups. Their presence in the macromolecules of the polymer composition makes it possible to improve the elastic, structural and mechanical properties, and to reduce the electronegativity of the adhesive film formed on the yarn during sizing. The optimal technological parameters of preparation of dressings based on the polymer dressing material for composition. At the same time, it was found that the use of these preparations makes it possible to give the coated cotton yarn good quality and technological properties, to produce fabric on high-performance weaving equipment with a reduction in breakage by 35-40%, and an increase in productivity by 5.0-10.0% It is revealed that in the case of dressing cotton yarn with the developed dressing compositions, a significant reduction in starch is achieved, which indicates the feasibility of using the developed composition in economic and environmental terms
