ABSTRACT:
There is provided a loop fastening material for engaging a suitable male mechanical fastening element for a backing substrate of an oriented sheet material having a first face and a second face and substantially continuously attached to at least the first face a plurality of discrete, multi-filament transversely expanded yarns, such yarn filaments providing open loop structures. The yarns are expanded by transverse orientation of the backing to which it has been previously attached by extrusion bonding, adhesive bonding or the like. The resulting loop fastener provides a low cost, readily manufactured loop having good fastening properties to hook materials.
