摘要：A process for draw-texturing polyester yarn which has been melt-spun at high speed. The process is performed on a conventional fal-twist texturing machine modified for drawing and for the u of an air-jet texturing device instead of a cond heater. The yarn is drawn at 1.3 to 2.0X draw ratio, fal-twist textured, and then air-jet textured to provide a yarn having a low boil-off shrinkage, resiliency and spun-like aesthetics.permission
