In the development of chemical technology for finishing textile materials, the development of new technologies for modifying cotton fabrics plays an important role. The use of natural polymers and proteins in such modification methods ensures their environmental friendliness. This article is devoted to the study of the physical, mechanical and sorption properties of cotton fabric modified with natural silk proteins. Based on the results obtained, it was determined that when treating the fabric with 4-6 g / l protein solutions, the weight gain increases to 5%, although its washability is from 2 to 3%. The physical and mechanical properties of cotton fabric samples increase as a result of modification. With an increase in the concentration of the modifier, the breaking load increases from 3.3 to 18.7% by warp. These changes by weft have higher values. Based on the results of the sorption analysis, the increase in the adsorption of modified samples by proteins (A, B) proves an increase in their active surface compared to unmodified cotton fabric, which contributes not only to the improvement of operational properties, but also to an increase in the sorption of the dye by the fiber.
