Abstract
A heated cylinder model was made to simulate wearing conditions of Japanese clothing and used in a study of the characteristics of thermal resistance when clothing made from 12 representative types of Japanese fabrics was worn. Fabrics for Japanese clothing have a comparatively low thermal resistance compared with fabrics for western clothing, and there is little difference among fabrics.
However, by adding a layer of air, thermal resistance was dramatically increased. On the other hand, air permeability was widely distributed. Particularly where there was an air layer underneath the clothing, thermal resistance was markedly reduced owing to a wind.
From these observations, we found that fabrics for Japanese clothing could be classified into following groups based on their features
