This difficult task must be based on the use of specially designed computer programs. Given the specifics of thread processing on technological machines of light and textile industry, when determining the relative tension in each zone, it is necessary to use a recursion algorithm, when the output thread tension from the previous zone will be the input for the next zone. The increase in tension in the areas of thread filling is explained by its interaction with the guides in the form of a cylinder and a torus, tensioning devices, compensators, thread break monitoring devices. Mathematical support of a computer program requires the development of models of these devices, taking into account the real physical and mechanical properties of complex threads and yarns and their real geometric and structural parameters. The main factor that affects the increase in thread tension is the force of friction. It characterizes the frictional properties of the threads and the conditions of their interaction with the guides in the form of a cylinder and a torus, tensioning devices, compensators, devices for monitoring the breakage of the threads. The coefficient of friction between the thread and the guide determines the value of the relative increase in tension in each zone depending on the type of materials of the thread and the guide. Formation of the base of frictional properties of raw materials processed on technological machines of light and textile industry, taking into account the guide material, will increase the accuracy of determining the change in relative tension in the zones when using a computer program. The difficulty of determining the coefficient of friction of the thread when it interacts with the guide surface in the form of a cylinder and torus is explained by the fact that it is not a constant value, but depends on the tension of the thread to the guide, the radius of curvature of the guide surface. To determine it, a combined method was used, in which the tension of the thread after the guide was experimentally determined, after which the coefficient of friction was determined according to known dependences. The base of friction properties of a computer program for determining the tension of the thread in the implementation of the recursion algorithm was formed for natural and synthetic complex threads and yarns in the form of a multidimensional array. A characteristic feature of the computer program is the ability to constantly update the database of friction properties for new types of thread.
