This study aims to obtain some concrete guides for designing thermally comfort pantyhose. For this purpose authors analyzed characteristics of the heat and water transfer properties of pantyhose and the factors affecting those properties. Furthermore, some experimental formulas for predicting those properties were found. The results obtained were as follows:
(1) Characteristic of each types of pantyhose were clarified: Zokki type was larger in weight and higher in heatretention, but lower in moisture regain than Kohhen type. Woollie-type was smaller in weight and larger in moisture regain than Kohhen type. And also Sheer-type was larger in moisture regain and moisture permeability. There were no differences in total heat loss H_t, wet heat loss H_w and water absorption area A_b between each types of pantyhose.
(2) Negative coefficients of correlation were obtained between dry heat loss H_d and fabric weight W or apparent density W/T, respectively. The coefficients of correlation between H_w and T or W were positive, but it between H_w and H_d negative. The coefficients of correlation between H_w and H_t was positive and high.
(3) H_d was able to be predicted accurately by using a regression formula in terms of W and S_d as variables.
(4) Similarly H_w was able to be predicted by using a regression formula in terms of W and A_b as variables, and H_t by using formula in terms of W, A_b and W/T. From these results, it could be understood that increasing of water absorption of pantyhose made its latent heat transfer increase. However, the precision of these regression formulas should further be improved in future.

The influence by textile properties on physical skin irritation was studied. The studied properties were fiber thickness and cross-sectional shape, fluffs on fabric surface, yarn twist, and yarn thickness. The influence on skin irritation was evaluated with Kawai's Method.
The physical skin irritation was dependent on fiber cross-sectional shape. The contact with fiber taps accelerated the skin irritation more than the contact with lateral face of fibers. Coarser fiber and yarn, and increased yarn twist resulted in more serious skin irritation.
