• the C8 fluorine-based water repellent contains perfluorooctanoic acid, perfluorooctanesulfonic acid, and the like. These compounds are degraded in the environment and in vivo. Since the decomposition products are accumulated in the environment and in the living body, the environmental load is high. Therefore, a fluorine-based water repellent that does not contain these compounds is desired.

Two or more of these may be combined.
• a synthetic fiber is preferable in terms of fiber properties, and a fabric made of polyamide fiber or polyester fiber is particularly preferable. If these are combined with, for example, polyurethane fibers, which are stretchable, and are used, for example, as a woven fabric, it is preferable because the stretchability can be controlled. Furthermore, among the polyester fibers, cationic dyeable polyester fibers are preferable in order to prevent migration sublimation of disperse dyes.
• the total fineness of the yarn constituting the stretchable fiber fabric is preferably 84 dtex (decitex) or less.
• the texture becomes hard.
• the stretchable fiber fabric is a knitted fabric, the unevenness of the fiber fabric surface becomes large. For this reason, film forming property is impaired.
