ABSTRACT:
A latent pressure-sensitive sheet material, e.g., fastener or closure having a discontinuous surface is made by applying a solvent-based pressure-sensitive adhesive by means of a gravure roll onto a flocked pile surface which is adhered to a substrate by a permanent adhesive. The flocked pile surface serves as a reservoir for the pressure-sensitive adhesive. The pressure-sensitive adhesive is wicked towards the face of the flocked pile surface upon face-to-face mating of two fasteners. The reservoir of pressure-sensitive adhesive and the wicking action enables repeated fastening and unfastening of two mated fasteners without substantial loss of locking power. The fasteners are particularly useful for seaming carpets. Also, the reservoir of pressure-sensitive material in one said fastener can be a curable or crosslinkable pressure-sensitive adhesive material, e.g., epoxy resin, and the pressure-sensitive material in the other said fastener can be a pressure-sensitive adhesive curing or crosslinking substance reactive with said curable pressure-sensitive adhesive material to cure or crosslink same, e.g., a polyamide curing agent for said epoxy.
