Abstract
Colored monofilament ultrahigh molecular weight polyolefin lines, and methods of making such colored lines are disclosed. The colorant can result in a product that provides a visual indication of metered length. When the colorant has a luminescent response to ultraviolet or infrared light, a line can change color based on the environmental conditions to which it is exposed. Methods of making the line can include feeding a substantially untwisted multifilament ultrahigh molecular weight polyolefin yarn; coating the substantially untwisted multifilament yarn with at least one 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.
