Abstract
Heatset, textured (e.g. stuffer box textured), continuous filament, nylon carpet yarn useful for making textured carpets is disclosed. The yarn is made from nylon 66 copolymer. Textured carpets made from the yarns of the invention have improved aesthetics and/or appearance retention characteristics as compared to textured carpets made from nylon 66 carpet yarns.
