Abstract
Method to produce a spun-like textured yarn comprised of one yarn which is substantially fully oriented and the other yarn is partially oriented. The method involves plying the yarns in the draw zone before being pre-textured. The ply point of the plied yarns is located above the entrance to the heater in the draw zone.
