A fabric, such as a loop fastener material, is finished by applying a foam to a surface of the fabric, the foam containing both a liquid binder and a powder. The binder is allowed to flow into pores of the fabric and coat fiber interstices of the fabric as the foam collapses, and is dried to stabilize the fabric. The powder is of a particle size selected to cause most of the powder to remain on the surface of the fabric while the binder is dried to bond the powder to the fabric surface. The powder, as bonded to the fabric surface, is activatable, such as by heat or RF or UV energy, to adhere the stabilized fabric to another surface or to provide a desired surface property. 1. A method of finishing a fabric , the method comprisingapplying a foam to a surface of a fabric, the foam comprising a liquid binder and a powder;allowing the liquid binder to flow into pores of the fabric and coat fiber interstices of the fabric as the foam collapses; anddrying the binder coating the fiber interstices, so as to stabilize the fabric;wherein the powder is of a particle size selected to cause most of the powder to remain on the surface of the fabric while the binder is dried to bond the powder to the fabric surface, andwherein the powder, as bonded to the fabric surface, is activatable to alter a surface property of the fabric upon activation.2. The method of claim 1 , wherein the powder is dispersed in the liquid binder as the foam is applied to the surface of the fabric.3. The method of claim 1 , wherein the foam comprises one part powder to ten parts binder claim 1 , by weight.4. The method of claim 1 , wherein the powder comprises at least 50 percent claim 1 , by weight claim 1 , of the foam.5. The method of claim 1 , wherein the binder comprises at least one of an acrylic and a urethane.6. The method of claim 5 , wherein the powder comprises at least one of co-polyamide and co-polyester resin.7. The method of claim 1 , wherein the powder claim 1 , as bonded to the fabric ...
