Abstract
There is increasing concern about the health effects of the severe thermal environment in urban area. Because of these situations, it is important to predict the thermal comfort for environmental improvements and designs. For predicting thermal comfort, surrounding environmental components such as clothing material are important, because clothing material has an impact on thermal exchange between exterior environment and human body. In this paper, the heat transfer property, the moisture transfer property and the radiative properties were measured in various conditions with using our own making experimental apparatus and the principles. The heat transfer coefficient and the moisture transfer coefficient were determined by the fabric and the geometric structure of clothing material. Environmental dependence was also considered. The evaluation technique for radiative properties such as reflectivity, transmissivity and absorptivity was established and these properties were successfully measured for cotton material in different colors. Finally, the effects of clothing material were totally found out by tracking the energy flow of clothing material, and the methodological approach for clothing function to human thermal comfort was established.
