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.

A pressure-sensitive fastener having a discontinuous surface comprising a flocked pile surface adhered to a base material by a permanent adhesive, and a reservoir of aqueous pressure-sensitive adhesive adhering to and between the fibers forming said flocked pile surface.
A method for making a pressure-sensitive fastener having a discontinuous surface comprising coating a base material with a permanent adhesive, flocking the permanent adhesive-coated base material with pile fibers and heat-curing the permanent adhesive to secure the pile fibers to the base material, spray coating the cured flock-coated base material with an aqueous pressure-sensitive adhesive, and drying the spray-coated cured flock material.
