Abstract

See full text

In an elongate strip material which can be severed into lengths to form at least a part of a fastener. The strip material comprises a backing and a multiplicity of lengths of polymeric monofilament having cross sections defining a plurality of radially projecting lobes, each length including a central bight portion secured in the backing, and two stem portions extending from opposite ends of the bight portion and projecting away from the backing. Enlarged heads are formed by heat at the ends of the stem portions opposite the backings, and the heads include hook-like portions spaced from the stem portions and projecting along the stem portions toward the backing that result from heating the ends of the monofilaments because of their lobed cross sections.
