Improvement of the quality of light industry products with simultaneous increase of energy efficiency is one of the main tasks of production today. The article is devoted to the topical issue of scientific justification of modes of heating of textile materials in the wet-heat treatment.The problem of the study is that traditionally, modes of heating are determined intuitively with quite a large margin. The scientific justification of heating modes can help reduce energy costs and increase the production efficiency.
The main objective of the study is to justify the minimum required parameters of heating of a polymeric material for a given deformation on the basis of modeling of thermomechanical dependencies along with the solution of the problem of deformation of the surface of the material.
The study demonstrated the possibility of creation of a surface of a product at longitudinal deformation of material while heating. On the basis of the solution of the differential equation of compatibility of deformation, we have defined the parameters of deformation and heating, which ensure the formation of a given surface. The temperature required for the deformation process was defined as the explicit function of the form of a surface that should be obtained. This dependence makes it possible to determine the scientifically justified temperature of heat treatment in deformation of polymeric materials that will help reduce unnecessary energy consumption when assigning temperature modes with a reserve, as it is at present.
