ABSTRACT:
A multifilamentary polymeric yarn capable of undergoing false twist texturing is passed through a friction disc aggregate under conditions (as defined) which produce periodic slippage with respect to the friction disc aggregate whereby recurring relatively tightly twisted areas measuring approximately 0.125 to 1.25 inch are substantially maintained along the length of the yarn intermediate recurring textured areas measuring approximately 0.125 to 1.25 inch which include a twist in the opposite direction. The feed yarn may be either partially oriented yarn or a drawn yarn. In a preferred embodiment the feed yarn is a partially oriented polyethylene terephthalate multifilamentary yarn. Unmodified texturing machinery can be employed. The resulting yarn is space textured and may be utilized to form a crepe fabric having highly desirable aesthetic characteristics.
