Reducing the natural risk of the people working in the open area by clothing based on textile operating systems

Abstract

Abstract The risk of a person’s hypothermia in the open area can be reduced by using heat-protective clothing based on textile operating systems. A method for studying unsteady heat and mass transfer in such clothes is proposed. Studies of heat and mass transfer processes in a package of traditional fabric materials and a textile operating system at an air temperature +5 °C were carried out. When doing light physical work, the efficiency of the packages is similar but the weight of the textile operating system is lower. When a human body is moistened by sweat, the textile operating system absorbs moisture better and removes it from the body, which improves the general condition of the person. With reduced physical activity the textile operating system restores the original heat-transfer properties quicker.
