CHARACTERISTICS OF COMPOUND MATERIALS FOR THE PROTECTIVE FOOTWEAR

Abstract

This paper presents a study on certain types of textile materials for working shoes destined for footwear upper. Thus, determinations will be made regarding the structure of the raw material and its nature, polyamide and other polyester yarns will be identified with chemical reagents. Subsequently, determinations will be made regarding the physico-mechanical properties of the materials for this type of footwear. The abrasion resistance will be determined by mass loss of the specimens subjected to friction. The air permeability of the composite materials will be determined on the basis of the pressure difference, and the water permeability is determined by the "artificial rain" method. It is worth noting that the footwear must have certain functions, also taking into account its purpose, such as protection against chemical agents, atmospheric agents, and mechanical actions. At the same time, the footwear must provide a certain microclimate for the foot to ensure its comfort during wear. In order to have a good maintenance value, leather substitutes should have functional indices close to the real leather. The quality and functionality of the protective footwear products is given by the characteristics and properties of the materials used in making them.
