Abstract
Abstract Disclosed is a carpet having a base fabric, pile yarns tufted to the base fabric and a backing layer covering a back surface of the base fabric. The light resistance of the dyed carpet and the anti-deteriorative properties of the pile yarns can be improved by covering portions of the pile yarns which extend into the backing layer with a resinous material containing finely divided carbon black.
