Abstract
A process for combining singles yarns, of different colors or dyeabilities, to form an apparent twist yarn. The process includes the sequential steps of individually and simultaneously drawing and texturing a plurality of singles yarns; converging the drawn and textured singles yarns through an air jet entangler that simultaneously entangles and tensions the yarn bundle; twisting the singles yarns in the yarn bundle about each other in alternate, or otherwise patterned, S and Z directions.
