A Model of Sweating Thermal Manikin

A sweating thermal manikin was constructed by collaborative research and development of Government Industrial Research Institute, Osaka and five textile companies to study the relations of heat and moisture transporting properties through clothings. A physical evaluating method of clothing comfort properties was established by using the measurements through the apparatus with sensors. The research and development were performed by Specific Regional Technology Development System of Agency of Industrial Science and Technology. The body was divided into ten segments; front and rear of chest, belly and buttock and limbs, in each segment of which the skin temperature and the amount of sweating can be independently controlled. The amount of sweating is simulated by regulating the air flow to the vapor generator. The climates within the clothes are measured by the thermometers, hygrometers, and heat flux sensors attached on the manikin. The performance of the manikin was evaluated by using shirts, underwears and long underpants made of cotton broadcloth and polyester taffeta.
