Abstract
A fastener member (10) useful for separable engagement with surface fibers of a low-loft, non-woven fabric, or the like, has a base web (12) and a multitude of fastener elements (14) formed with and extending from the base web (12). The fastener elements have a profile that comprises an elongated stem portion (22) adjacent the base web (12) and including at an acute angle to the base. A crook portion (24) is formed on the end of the stem and is directed oppositely to the direction of inclination of the stem, being exposed for engaging a mating fastening member (32). The acute angle of the stem of the elements (14) enables them to flex toward the base. Offset pair of such elements (14) can operatively move in a pincer-type motion to engage fibers (32) and to retain engaged fibers. Other element configurations are disclosed. The fastener member has particular application for fastening of disposable products such as garments and diapers.
