Abstract
This invention relates to an improved process for making colored polyamide fibers. The process involves adding about 0.1 to about 3.0 weight percent polycarbonate to a polyamide melt prior to extruding the melt through a spinneret to make colored fibers. The invention also encompasses the resultant fibers.
