Chelysheva S. Normative documentation improvement of energy-saving modes of textile materi-als` wet-heat treatment

The research object is the process of wet-heat treatment of textile materials, the research subject is energy-saving modes of wet-heat treatment of textile materials and relevant regulatory documents. The purpose of the research is to increase the efficiency of the textile production by justifying the energy-saving modes of wet-heat treatment taking into ac-count the parameters of the thermomechanical characteristics of textile materials. The research methods include methods of system analysis that allows to discover the interaction and structural-logical connections between different elements of the process and structural components of regulatory support, methods of expert evaluation and expert research to justify the proportion of components of the production process in the final quality indicators of sewing products, matrix algebra methods and linear mathematics for compilation and analysis of matrices of significance and determination of significance of normative support of various elements of the process, methods of correlation, determination, linear and nonlinear regression in the process of approximation of experimental dependencies, methods of mathe-matical theory of statistics, methods of planning an experiment in the process of experimental determination of thermomechanical characteristics, modern methods of contactless temperature determination, chemical analysis and methods for deter-mining the hardness of water. The scientific novelty of the results obtained is as follows: 1. For the first time, dynamic indicators of intensity of growth of deflections, which allow to determine necessary temperature indices for conducting the wet-heat treatment, for designing energy-saving technological processes are grounded and determined as standardized indicators of the thermomechanical process. 2. For the first time a mathematical model of textile material deformation under the influence of temperature and force loading was developed, which allows formulating recommendations on the temperature distribution on operations of the wet-heat treatment to ensure the accuracy of the production of parts with reduced overall energy consumption. 3. The methods of approximation of thermomechanical curves based on nonlinear regression methods have been improved, which allowed to determine the normalized parameters of the energy-efficient modes of the wet-heat treatment. 4. Further development of the classification of the principles of heating textile materials during the wet-heat treatmentwas found, taking into account the mathematical model of the deformation of textile material, which allows rational distribution of temperatures for different types of surfaces
