Main purpose

Used to test the thermal insulation performance of textile clothing, sleeping bags, cold clothing and other products - Warm body dummy testing method. During the process of simulating heat exchange between the human body, textiles and clothing, and the environment, the thermal resistance of the clothing is measured and calculated based on the relationship between physical parameters such as the temperature difference between the skin surface temperature of the warm body dummy and the ambient temperature, and the non evaporative heat dissipation rate per unit area of the body surface. The overall thermal comfort performance of textile and clothing products is comprehensively tested through real simulation.
