ABSTRACT:
Bulked random copolyamide yarns having enhanced dyeability as compared to comparable nylon 6 fibers are disclosed. The random copolyamides contain from 80 to 96% by weight of nylon 6 units and 4 to 20% by weight of nylon 6,6 units with from 90 to 94% nylon 6 and 6 to 10% nylon 6,6 being the preferred range. Further increases in dyeability are obtained by steam heat-setting the yarns.
