ABSTRACT:
The abrasion resistance of fabric composed partly or wholly of recycled wool fibers (reprocessed or reused wool) is increased by impregnating the fabric with an aqueous solution of an acrylate monomer containing a polymerization initiator, an acid, and, preferably, a surfactant promoting contact of the fibers with the solution. The fabric, which has been impregnated at a temperature below the polymerization initiation temperature, is washed with water to remove the impregnating solution from the exterior scaly surface of the wool fibers while leaving the solution within the fiber cortex, and thereafter the fabric is cured by heating it at a temperature above the polymerization initiation temperature of the acrylate monomer. The process provides a means for increasing the durability of the fabric without appreciable modification of other desirable properties of the fabric.
