TECHNOLOGY OF SHAPE FORMATION IN VOLUME AREAS OF SEWING PRODUCTS PARTS USING A VACUUM INSTALLATION TO FORM A CLOSED TECHNOLOGICAL SPACE

This article provides a detailed analysis of the processes of wet heat treatment in the manufacture of the upper range, describes the principle of operation of a special vacuum forming device and detailed characteristics of various degrees of vacuum. as well as the theoretical foundations of the aerodynamic passage of air in a vacuum mode during shaping and the results of studies of several types of suit fabric for breaking load, the corresponding results correspond to the above studies. The substantiation of the sizes of perforations is carried out depending on the limiting state of the deformable tissue, characterized by the breaking load
