Claims17
In a process of preparing a dyed textile fabric wherein a dye solution is deposited onto a textile fabric, the improvement comprising coating the dyed textile fabric with (i) a glyoxylated acrylamide-diallyldimethyl ammonium chloride resin and (ii) an aminopolyamide-epichlorohydrin resin, wherein the glyoxylated acrylamide-diallyldimethyl chloride resin and the aminopolyamide-epichlorohydrin resin are coated onto the dyed textile in a weight ratio of about 0.5:1 to about 5:1.
In a process for after treating a dyed textile fabric, the improvement comprising aftertreating the dyed textile fabric by applying a finish in an amount sufficient to improve wet crockfastness, the finish comprising effective amounts of a blend of (i) a glyoxylated acrylamide-diallyldimethyl ammonium chloride resin and (ii) an aminopolyamide-epichlorohydrin resin, wherein the glyoxylated acrylamide-diallyldimethyl chloride resin and the aminopolyamide-epichlorohydrin resin are applied in a weight ratio of about 0.5:1 to about 5:1, and drying the resins in the finish in situ on the textile fabric.
