    We have investigated the effect of the prepared artificial acid rain on the strength and the elongation of cotton yarn. The artificial acid rain solutions are a standard solution (pH4.0) and two kinds of solution (pH2.2) which correspond to the acid fogs. A cotton fabric was immersed in the solution, followed by drying indoors or in the sun. Processes of immersion, drying and rinsing were repeated 10 times, then the strength-elongation test for the warp yarn was carried out. When the specimen was treated with the lower pH solution and dried in the sun, the decrease in cotton yarn strength ranges from 19 to 26%. This decrease of strength is responsible for the hydrolysis of cellulose at junction points accompanied with the formation of hydrocellulose.

    This paper aims to make clear the influence of the hygroscopicity on thermal properties of pantyhose. The heat and water transfer properties of a prototype pantyhose, in which hygroscopic cupraammonium rayon filament yarns are mixed, have been examined as compared with those of usual pantyhose made of nylon filament yarns.
    The results obtained are as follows:
    1) The dry heat loss (Hd) is closely related to structural properties (thickness T, weight W, and stitch density Sd) of pantyhose. Hd is able to be predicted accurately by using a regression formula in terms of W and Sd as variables.
    2) The moisture transfer rate (Wn) of pantyhose, in which cupraammonium rayon filament yarns are mixed, is about 30% higher than that of nylon pantyhose in the test simulating insensible perspiration condition. Wn is able to be predicted by using a regression formula in terms of regain (R), W and Sd as variables.
    3) The pantyhose, in which cupraammonium rayon filament yarns are mixed, is higher in wet heat loss (Hws) and is also shorter in the duration of drying time (t) than those of nylon pantyhose in the test simulating sweating condition. Hws is able to be predicted by using a regression formula in terms of water absorption area (Ab), R and Sd.
