Relationship Between Distance of Clothing and Heat Flow Value Through Clothes in Wear

Abstract

Skin temperature, clothing surface temperature and heat flow value through clothes were measured for various distance of clothing layer in each position of body respectively. The results are as follows. 1) The distance between clothes in each items partitionaly were obtained by the method to take off the direction from the most outer wear to under wear. 2) In proportion to the increase of distance of clothing, clothing surface temperature decrease almost exponentially, and heat flow value had the same tendency. 3) If the distance is equal, heat flow value differ with a kind of clothing material, and the facts is the same about a kind of position of body. 4) Thermal insulation value of air, I_a in this study was different from Burton's I_a under the same thermal environment. 5) The effects of thermal insulation of various clothing assemblies obtained in each position of clothing respectively.
