Abstract

PURPOSE: To improve the operating efficency of drawing (false twisting) of the title fiber, by interlacing a cooled melt spun filament yarn slightly with a unit, and by winding the yarn to take out the undrawn yarn smoothly.
CONSTITUTION: The filament yarn 9 extruded from the spinneret 2 of the head 1 is cooled by the air from the blowing unit 3, passed through the stack 4 and the oiling roller 5, and interlaced by the unit 6 with conditioned moisture and controlled pressure. The degree of interlacing (CF) must be ≤20, preferably 3W10. The higher degree causes wale streaks in fabrics. The yarn consists of polymers a and b having poor compatibility, which are finely divided into layers or islands-in-sea, including filaments wherein islands are partly exposed or combined in the form of bimetal.
