To find out the relation between moisture and water transport properties of clothing materials and wear sensations, in this paper, physiological factors and physical properties of fabrics relating to subjective wear sensations were clarified. Three healthy adults were chosen as subjects in the experiment. The experiments lasted for a total of 1 hr each, and the subjects followed an intermittent motion consisting of rest and walk on a treadmill. As specimens, four shirts consisting of cotton, polyester, cotton-polyester blended and polyester grafted with hydrophilic groups were used.
The results are summarized as follows :
1) The subjective estimation of thermal, humidity, tactile and comfort sensations vary in the same way in the wear triales.
2) The variation of the relative humidity in the air layer next to the skin is similar to those of the above-mentioned sensations, that is, it is considered one of a characteristic index governing the wear sensation. However, the amplitude of the variation is not perfectly reflected on the sensations.
3) Total sweat secretion during experiments increases as the rise of the humidity occures earlier and steeper.
4) A significant correlation was found between the comfort sensation and the total amount of sweat.
