\u00a0 \u00a0 \u00a0Based on the implementation of the recursion algorithm, computer program modules have been developed to determine the thread tension in the working area of the knitting machine in the case of using a washer tensioner. The main forms of the computer program for the implementation of the recursion algorithm for determining the technological effort in the working area of the knitting machine for the case when the washer tensioner is used as a thread tensioner. The program modules of the program for determination of technological efforts in a working zone on round knitting machines taking into account diameter of section of a thread, its physical and mechanical properties for a wide range of complex threads and yarns are presented. The software modules provide the possibility of setting the law of changing the diameter of the thread in the form of a harmonic function or an arbitrary function of the user using inverse Polish records in the form of a translator. Simple circular knitting machines are associated with the elimination of thread breakage. This negatively affects the performance of circular knitting machines, reduces the quality of knitted fabrics. The main parameter for optimizing the thread feed system on circular knitting machines is the minimum required tension in the area of formation of the knitted fabric. The breakage of the threads during processing on the process equipment is due to the imperfection of the thread feeding system on circular knitting machines and its components. The largest number of breaks falls on the area of the washers of the thread tensioning devices. Studies of the influence of the design of the washer device of the thread tension on the conditions of its interaction with the thread, taking into account its non-uniformity in the diameter of the cross section are important in determining the thread tension in the working area. The thread tension increases when passing through the refueling zones of the thread feed system on circular knitting machines. This increase is due to the interaction of the thread with the washers for tensioning. The maximum value of tension will be in front of the working area of circular knitting machines. Minimizing the tension in front of the working area of circular knitting machines is important for improving the technological processes of knitting from the standpoint of improving the productivity of circular knitting machines and the quality of products. Thus, the topic of this article is relevant, which is important for improving the system of thread feed on circular knitting machines, the design of existing thread tensioning devices and the development of new ones.\u00a0 Development of special computer programs for determining the tension in the working area of the formation of knitted fabrics on circular knitting machines allows you to quickly determine the necessary technological parameters, adjust both the structure and components of the thread feed system on circular knitting machines to obtain the minimum required tension in the working area of the formation of knitted fabrics. Objects and methods of research. Thread washers are an integral part of the thread feed system of circular knitting machines. The imperfection of the design of the thread tension washers on circular knitting machines leads to fluctuations in the thread tension during its processing and violation of the technological regime. The theoretical basis for solving scientific and technical problems are the works of leading scientists in the fields of technology of textile and knitwear production, textile materials science, thread mechanics, elasticity theory, mathematical modelling. Methods of theoretical mechanics, resistance of materials, experimental planning and statistical processing of research results were used in theoretical and experimental researches.
