The influence of technological conditions of forming and fixation on the fitting of the footwear-upper to the foot

The influence of different technological conditions of forming and heat forming of foot wear on its ability to fit to the foot in the article one studied. The coefficient of form stability and the residual meanings cyclic deformation of materials systems after repeated extension by different conditions of technological treatment are determined. The mathematical dependencies of form stability coefficient and residual technological treatment on technological parameters are defined. The rational conditions of technological treatment of materials systems with different combination of materials ensuring the high footwear form stability during the production and good fitting to the foot during the wearing are determined.
