ABSTRACT:
A coherent, bulked, continuous-filament, heather-dyeable yarn having a more natural, spun, wool-like appearance in carpets consists of lighter dyeing filaments which comprise 20-50% of the total yarn filaments and which are 15-45% longer than the darker dyeing filaments in the yarn. The yarn is produced by overfeeding the lighter dyeing filaments to a greater degree than the darker dyeing ones through a turbulent fluid-jet intermingling zone.
