Evaluation of heat-proofing properties of upper packages of materials of industrial shoes

The article presents a fully developed automated measuring bench station, which allows quick and costs-efficient evaluation of heat-proofing properties of upper shoe materials. Methods for testing samples on the measuring bench are described. Thermo-physical characteristics of different compositions of upper packages of industrial shoes are studied, the influence of individual components on the total thermal resistance of systems of material are revealed, the most optimal combinations of components in terms of heat-proofing properties of shoes are determined. Results obtained in the course of the work allow to carry out a rational configuration of upper packages of insulated shoes and to predict their insulation properties on the stage of design-technological preparation for production.
