Abstract
An article can be releasably attached to a fabric or other foraminous substrate by means of a pressure-sensitive adhesive tape fastener, the backing of which has an array of bluntly pointed stems protruding beyond the pressure-sensitive adhesive. The back face of the fastener can have an adhesive layer by which it can be adhered to a sanitary napkin, and the napkin can be releasably attached to an undergarment by allowing the stems to penetrate into openings in the fabric of the undergarment until the pressure-sensitive adhesive becomes releasably bonded to the fabric. The fastener can be more supple and less obtrusive than are "Velcro" fasteners and can be produced at significantly lower cost.
