Methods of an intensification of processes of hydrothermal treatment for giving to materials of light industry of properties of molding capacity are offered. These operations are carried out before formation, the various ways one of which is the sorption way of moistening. The intensification of an external mass exchange at this way can be carried out at the expense of temperature increase, humidity and the speed of movement of damp air, application nozzle обдува, preliminary pumping out. At the expense of application of an oscillating mode, the mechanism of transfer of moisture in a material at the expense of application of vacuum the intensification of an internal mass exchange can be carried out So that to intensify a sorption way of moistening vacuum application, and as at the expense of increase in coefficient of the external diffusion, which influence on the speed of sorption of moisture approximately in 100 times more sizes of coefficient of internal diffusion is necessary. In a different way is the contact (thermal diffusion) way of moistening different from other ways way of movement of moisture under the influence of a temperature gradient at the expense of all three types of thermomoisture pro-water content. On the basis of the analysis the most effective, from existing ways of hydrothermal treatment for giving to shoe materials of properties of molding capacity - from the point of view of an intensification of process and influence on physico-mechanical properties of skin, application of vacuum allows to change the mechanism of transfer of moisture in a material with diffusive on effusions which speed considerably surpasses the speed of the diffusive.
