1. A method of improving the resistance of fabrics and textiles to pilling said method comprising 1) applying to the fabric or textile an anti-pilling effective amount of a curable/cross-linkable aqueous composition comprising (I) a polymer/polymer forming component and (II) a silicone component, wherein the polymer/polymer forming component (I) comprises either (a) a polyurethane dispersion comprising at least one cross-linkable aliphatic and/or cycloaliphatic polyurethane and a cross-linker for effecting cross-linking of the polyurethane, (b) an acrylic emulsion comprising at least one self-crosslinking acrylic polymer or acrylic copolymer or (c) a combination of both (a) and (b) and the silicone component comprises a silicone dispersion, and the total solids/solids forming components content of the composition is from 70 to 1 wt % of the composition based on the total weight of the composition and wherein said anti-pilling effective amount is from about 0.05 percent to about 4 percent based on the weight of solids and solids forming components to the weight of the fabric or textile to be treated and 2) subjecting the treated fabric to conditions to cure and cross-link the curable/cross-linkable composition whereby the treated fabric retains improved antipilling properties, as compared to untreated fabric, even after four washes.
