Comparison of the Effect of Clothing Materials and the Openness of Garment on the Microclimate of the Skin Simulating System

The purpose of this study was to compare the effect of clothing materials and the opening of the garment on the microclimate of the skin simulating system during the coupled heat and moisture transfer. To determine the effect of size and location of openness of the garment, openness was simulated by removing parts of the spacer ring of the modelling system. To evaluate the changes of humidity and temperature of air layer in the system, buffering indice, Kd and Pr, and efficiency of openness were determined. When the openness was imparted to the system, the transport rate of heat and moisture increased abruptly; at the total openness of 26.4%, which simulated the openness of neck, armhole and waist, Kd increased at least more than three times of the closed system. As the openness increased, the effect of clothing materials decreased gradually to lose its effect at the 60% openness and approached the value of nude. Temperature regulating index showed, however, higher value than nude which was apparently due to the still air layer.
