Abstract
Abstract A latent pressure-sensitive fastener having a discontinuous surface is made by spraying an aqueous pressure-sensitive adhesive 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 loss of locking power. The fasteners are particularly useful for seaming carpets.
