Abstract
So-called sticky or close-fitted feeling is an important factor of uncomfortable feeling under perspiration. In this study, the phenomenon of stickiness or close-fitness was simulated physically by the measurements of the absorption of liquid and the interfacial sliding resistance in existence of the liquid of a drop in the interface between a polypropylene film and a fabric. The effects of a fabric on it are discussed and the following results were obtained :
(1) Sliding resistance is influenced to the nature of the wettability of fabrics.
(2) The value of the integration along the curve of the relation of the sliding resistance and the lapse of time, S' is small in the wettable fabric of the small density used the thich threads of the twist relatively.
(3) The experimental equation of the vertical force of the interfacial tension of the liquid which works in a fabric was assumed as F=2 (T/g) ·sin (θ+ α) · (lN).
