ABSTRACT:
There is disclosed a colored high-tenacity fiber of ultra-high molecular weight polyethylene which is obtainable by spinning a solution of ultra-high molecular weight polyethylene and a dye for coloration to form solvent-containing filaments and drawing the solvent-containing filaments. The colored high-tenacity fiber of ultra-high molecular weight polyethylene has a tensile strength of at least 28 g/d and a tensile modulus of at least 700 g/d. The dye is substantially soluble in the solvent at the melting point of solvent-containing filaments which are obtained by spinning a solution of ultra-high molecular weight polyethylene and the dye is substantially uniformly dispersed in the core portion of the fiber. Also disclosed is a process for producing a colored high-tenacity fiber of ultra-high molecular weight polyethylene.
