Abstract
Purpose. The expressions for tension and shape of the filament axis with anisotropic friction properties and nonlinear dependence of the friction force from the normal pressure in the contact zone. Methods. Studies based on the use of elements of differential geometry, calculus, mechanics thread. In the integration of differential equations, numerical methods used and the appropriate software. Scientific and practical results. Improvement of many technological processes of textile and light industry should be based on theoretical and experimental studies of the interaction of threads with the working bodies of the process equipment. Theoretical study are to determine the shape and the axis of the thread tension during the interaction with its guide surfaces. The article presents the results of studies of the interaction with the yarn guide surface with anisotropic friction properties and nonlinear dependence of the friction force from the normal pressure in the contact zone. The results of the study can be used to improve the processes and equipment in the textile industry. Keywords: yarn guiding surface, the coefficient of friction, the strength of the normal pressure, the radius of curvature.
