Total 4032 data were collected including male, female, no major, and major people who are studying clothing and textile in college. Handle were observed by subjective method as the washing was repeated for 4 kinds of material which have different water vapor transmission, and the change of water vapor transmission each others. The data were analysed for t-test, ANOVA, factor analysis, and Duncan multiple test. Consumers evaluated that water and water vapor permeable coated fabrics were less elasticity. There were little difference in wrinkles, thickness, and luster for polar adjective words. Clearer evaluation was shown by female group or major group than others. The results of factor analyses for 18 polar adjective words on subjective handle test yielded 4 factors, that were 'elastic property', 'surface property', 'thickness and weight property' and 'thermal and rigid property'. The surface properties were deteriorated remarkably as washing was repeated and significant difference were observed. Significant differences of subjective handle in 4 factors were shown in fabric types.

Clothes and environments as one system. Clothes play their role in adjustment to various environments and should be studied with humans as a research. The purpose of this study was to compare the wearing sensation depending on four different kinds of summer girls' high school uniforms on different cotton/polyester/polyurethane blend ratio for the different elasticity. The experiments were conducted to measure the comfort sensation. For this experiment, 4 healthy female students were taken as subjects. We checked the regional skin temperature, physiological responses(body temperature, blood pressure and pulse rate), subjective sensations(thermal, humid and comfort sensation) at 25℃, 65% R.H. The results are as follows: 1. The skin temperature of forehead and abdomen were continuously high, but those of forearm and leg were irregularly changed. 2. In the mean skin temperature, the more elasticity was, the lower it was. 3. Body temperature was slightly increased, however, the range of the increase was very little. 4. In the microclimate of all experiment clothes, the temperature and humidity in the back part of human body were higher than those in the back part. 5. The thermal sensation for the lowest elastic material was better than the others. The humid sensation was similar in four different materials. And The comfort sensation for the higher polyurethane blend ratio was better than the others.
