Abstract
Abstract A velvet type fabric tape for use as closing means or fasteners for garments, curtains and the like. The fastener tape comprises a woven foundation structure, and a number of material-engaging elements raised from one of opposite surfaces of the foundation structure. Each of the material-engaging elements is in the form of a mushroom-shaped loop having a pair of stalks juxtaposed on the foundation structure and an umbrella-shaped head borne on the stalks. The umbrella-shaped head includes a pair of material-hooking eaves each projecting from one of the stalks substantially parallel to the foundation structure for trapping loops on a companion fastener tape.
