摘要:
A fiber-made surface fastener provided on one surface of a flat base cloth with a joining surface having many fiber-made engaging elements. When the structure of the base cloth and the constituting yarns of the surface fastener are specified, a ratio (A/B) between the area (A) of the 100 Hz-3000 Hz region of a sound spectrum of a peeling-off sound Fourier-transformed in a 100 HZ-15000 Hz region and the area (B) of the 3000 HZ-15000 Hz region can be set to at least 0.4, whereby a tone produced when the surface fastener is peeled off a surface fastener-attaching product is shifted toward a low tone side to render an unpleasant noise small in tone and reduce an unpleasant feel.
