    Panty hoses on the markets are usually classified into four groups of wolly, sheer, kennel, and support types. For samples of these four types, the wearing test was performed with three subjects of different sizes. Changes of dimensions in the wale and course directions were measured at 5 minutes after the pulling on and at the end of the 5 hours test, and also 5 minutes and 16 hours after pulling off the panty hose. The slippage were obtained from the movement of marked lines.
    Area enlargement at 5 minutes after pulling off increases proportionally with the increase in the difference in sizes between corresponding parts of subjects and panty hoses, and increases with the latter in general. The largest slippage during wearing was observed in the sheer types, and has tendency to restrain the increase in the area enlargement.

    In order to make clear the relation between the fatty acid composition of soaps used in bulk wash liquid and the detergency of foam washing, we used sodium soaps and potasium soaps which composed from saturated fatty acids (C12-C18) or unsaturated one (C18*), searched the foaming property, washed the natural dirt on the collar and the artificial cluster dirt by C type of foam washing machine, and obtained following results.
    1) With increasing carbon number of fatty acid soap at 70°C, the foaming power and the foam stability increased, and the blow ratio decreased. Unsaturated C18*-soaps showed the foaming properties between saturated C12-soaps and C14-soaps. These properties are closely related to the viscosity of bulk liquid and the hydrolysis ratio of the soaps.
    2) Palmitic acid soaps (C16) and stealic acid soaps (C18) showed the best detergency in immersion washing. But in the foam washing, the best detergency of oily soil and protein soil was obtained with mylistic acid soaps (C14) and palmitic acid soaps, which have high permeability, and the best detergency of particulate soil was obtained with palmitic acid soaps and stealic acid soaps, which create strong and thick foam films.
