Abstract
A method of making colored monofilament ultrahigh molecular weight polyolefin fishing line, comprising the steps of feeding a substantially untwisted multifilament ultrahigh molecular weight polyolefin yarn; coating the substantially untwisted multifilament yarn with a colorant; twisting the coated multifilament yarn; and heating the twisted multifilament yarn to a temperature and for a time sufficient to at least partially fuse adjacent filaments together while stretching the yarn. The resultant product is a colored monofilament fishing line that has improved color-fastness and abrasion resistance.
