摘要：
An improved process for melt-spinning a pigmented hexamethylene adipamide fiber from a melt blend of a polymer and a colored pigment wherein the polymer is a random interpolyamide or a block polymer having two different difunctional recurring amide-forming moieties other than those which form hexamethylene adipamide is disclosed along with pigmented hexamethylene adipamide polymer fibers having tenacities greater than 7.5 or even 8 grams per denier.
