Abstract
So-called sticky feeling is an important factor of uncomfortable feeling under perspiration.
There are some old papers about the phenomenon of stickiness.
In this study, the phenomenon of stickiness was simulated physically by sliding resistance in the interface between a polypropylene film and a wet fabric.
The cause of sliding resistance and the effects of a fabric on it are discussed and the following results were obtained:
(1) Sliding resistance is a function of water content and has a maximum value.
(2) Sliding resistance is influenced to the nature of a fabric-material (wettability or unwettability) and the structures of fabric (thickness, size and density of a texture).
(3) Sliding resistance is caused by interfacial tension of water which works at a unit of texture.
