Abstract
A female member for a hook-and-loop fastener is provided. Even when the hook-and-loop fastener part is deformed or an instantaneous impact peel force is applied to the fastener part, the female member does not peel off the male member. When the male member is peeled from the female member, no fluffing caused by shedding of a fibrous material occurs. The female member for a hook-and-loop fastener is constituted of a fibrous material and can engage with a mating male member. The female member is composed of: dense fiber portions arranged in rows and having a high density of the fibrous material; and sparse fiber portions arranged in rows alternately with these dense fiber portions and having a lower density of the fibrous material than the dense fiber portions. The dense fiber portions deform elastically, and this prevents undesirable peeling and diminishes fluffing.
