Investigation of the properties of textile materials for protection from the thermal effects of an electric arc

Abstract

Every year more and more attention is paid to the development of protective clothing, especially if it is connected with the manufacture of work clothing for protection against thermal effects. The protective functions of overalls, and hence the health of others, largely depend on the quality of the materials from which special clothing is made. As objects of study, 3 tissue samples of different fibrous composition were taken. The paper presents comparative characteristics of the physical and mechanical properties of the tissues under consideration. The level of protection is determined by the maximum value of the incident energy of the heat flow of electrical energy, at which protective clothing is able to protect the user from burns of the 2nd degree. The levels of protection of the top of the protection of the top of the clothing are considered, as well as various types of multilayer packages of materials are considered. As a result of the study, packages of materials were identified that meet the requirements for resistance to convective heat.
