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 .
