Abstract
A filament yarn of greater than 60 percent extensibility is combined with a carrier yarn. The combined yarn is false-twisted under tension in a unit employing rotary friction elements so that the filaments of the extensible yarn break intermittently while the carrier yarn remains intact to produce a spun-like textured yarn. The tension during false-twisting may be increased to a level at which the broken filaments snarl and form slubs in the yarn. The process may be carried out with no heat setting of the false-twist to form crimps. Suitable extensible yarns include undrawn and partially-orientated yarns, polyamide and polyester yarns, and suitable carrier yarns include fully-drawn filament yarns and spun yarns.
