Abstract
A method of making colored multifilament ultrahigh molecular weight polyolefin yarn, including feeding at least one substantially untwisted multifilament ultrahigh molecular weight polyolefin yarn, coating the substantially untwisted multifilament yarn with a coating composition comprising colorant in a thermoplastic resin carrier, with the coating composition being adhered to the filaments of the multifilament yarn, and heating the multifilament yarn while stretching the yarn without fusing of the filaments of the multifilament yarn. The resultant yarn is a colored multifilament yarn having improved color-fastness. The thermoplastic resin has a lower melting point than the filaments of the multifilament yarn. Preferably, a plurality of the substantially untwisted multifilament ultrahigh molecular weight polyolefin yarns are processed together. Articles formed from the colored multifilament yarns may be prepared and subjected to a heating step to provide a colored surface coating of the thermoplastic resin over the article.
