Influence of the Deformation of the Thread Section in the Direct Contact Zone on the Value of Acceleration of the Central Axis Points

Determined projections of the acceleration vector in relation to the arc length coordinate of the thread axis through components that define the degree of thread compression in the contact zone. Solving the challenges faced by the textile and light industries in increasing the production of fabrics and knitted goods based on improving the productivity of existing equipment and employing modern technologies, grounded in the latest scientific achievements, has significant economic and technical importance. The number of breakages can be significantly reduced by using high-quality raw materials and optimizing the conditions of thread processing on technological equipment, where interaction with guiding and working elements of large and small curvature occurs. Theoretical foundations for the accelerations of points on the thread axis, considering compression during its movement along a guide of large curvature, have been developed.
