Abstract

A mushroom-type hook strip that can be used in a hook-and-loop mechanical fastener. The hook strip comprises a homogeneous backing of thermoplastic resin and, integral with the backing, a high density array of hooks including stems projecting from the backing and circular disc shaped heads at the ends of the stems opposite the backing. The large number, small size, and shape of the heads on the hooks allow them to engage the fibers in conventional types of fabrics and non-woven materials that are not normally used as the loop portions of hook and loop fasteners.
