The object of the presented research is the technological process of manufacturing clothes for professional sports fencing. The subject of research is the quality of the knitted joints, which are regulated by technical requirements and require special attention when designing an assortment of clothes for fencing athletes.The research methodology is based on the analysis of scientific literature, measurement of mechanical properties and modeling of technological parameters of knitted joints of fencing clothes. In order to determine the effect of the number of stitches on the breaking strength and the longitudinal deformation of the knitted joints of fencing clothes, mathematical modeling of the manufacturing process using the experimental design method is used. The choice of the experimental design is associated with determining the number of experimental points and their placement in the factor space, which will make it possible to obtain the necessary information for making a decision with a relatively small number of experiments. During the study, methods were used to determine the breaking strength and extended deformation of the joints. A feature of the study is the determination of rational technological parameters of the knitted joints while maintaining the necessary tensile strength and a certain level of longitudinal deformation. The rational parameters of the number of stitches in the seam-sewn and finishing stitching lines for the studied materials of fencing clothes are those for which the tensile strength of the seam is ≥970 N and the longitudinal deformation does not exceed ± 2.0%, namely: t– (5.0÷6.5) stitches/10 mm, h–(3.0÷3.5) stitches/10 mm.The obtained results prove the possibility of using mathematical modeling methods to predict the quality of knitted joints of clothing parts for professional sports fencing. This approach is of practical importance and can be applied both at the stage of designing the technology of manufacturing clothes for professional sports fencing when choosing processing modes for new materials, and at the stage of manufacturing and quality control of performed operations.
