The Republic of Uzbekistan is a member of the group of countries with a hot climate, located in the interior of the continent, far from the seas and oceans, and is characterized by a dry, sharply continental climate. Working conditions in an enclosed space differ significantly from working conditions in an open space. Safe working conditions for workers working in an enclosed space are largely determined by their provision of high-quality work clothing, which reliably protects against the effects of adverse climatic and industrial factors. At present, workwears for workers in production is made mainly from imported fabrics, and in terms of its operational, hygienic and technological characteristics does not fully correspond to the climatic conditions of Uzbekistan. In order to increase the productivity of workers, the design and development of new special clothing, taking into account all requirements, is an urgent problem. This article is devoted to the development of the optimal fabric for workwears and the selection of sewing threads for joining parts of special clothing from fabrics of new structures. To achieve this goal, special-purpose fabrics have been developed, and their physical and mechanical properties have been studied. When developing a new range of fabrics, special attention was paid to increasing the hygroscopicity of the fabric. And also the assessment of the strength of sewing threads was investigated by determining their shrinkage and breaking load before and after sewing, since the threads produced are quite large, which allows you to choose the optimal fittings for the production of any products. And this is very important, since not only the consumer characteristics of clothing, but also the efficiency of the sewing production itself will depend on the correct choice of sewing threads. A recommendation was given to select a sewing thread and stitch length for sewing overalls from fabrics of new structures for workers in the automotive industry of Uzbekistan. When sewing worwwear made of cotton+modal fabric, it is recommended to use the minimum thread tension during the sewing process, since stretched threads can contribute to shrinkage during garment care. According to the indicators of shrinkage of sewing threads of various assortments for workwear made of "cotton+modal" fabric, polyester, lavsan-cotton sewing threads are recommended for workers in the automotive industry of Uzbekistan, since in all respects these threads are suitable for sewing special clothes.
