ABSTRACT:
A hook fastener portion for use in a hook and loop fastener that has a woven backing with portions of pile monofilaments projecting from its front surface providing hooks adapted for making releasable engagement with loops of the fastener. Only a layer of thermoplastic material along a rear surface of the backing and the mechanical engagement of the portions of the pile monofilaments woven into the backing anchor the monofilaments in the backing, and that layer of thermoplastic material can be a hot melt adhesive used to adhere the hook fastener portion to a substrate.
