The task of clothing is to provide a state of physiological comfort. The criterion for identifying the physiological comfort is to ensure thermal equilibrium of the body. The possibility of heat exchange between human body and the environment is the result of processes: radiation, convection, evaporation of sweat, breathing. Depending on the intensity of effort and environmental conditions the contribution of these processes is different. The state of thermal comfort is affected by the biophysical properties of clothing: aeration, water vapor permeability, hygroscopicity, water resistance and thermal insulation [9]. The research of heat transport is carried out in dynamic conditions using a new method of "artificial skin model", with which the amount of heat diffusing through the sample is determined. Another method for measuring the heat flux and the analysis of thermal capacity of textile products is with the use of the alambeta device. The article presents the results of thermal insulation (for 15 samples) that were conducted on the device of alambeta and "artificial skin model."
