Abstract

PURPOSE: To obtain the title fibers of high performance usable for waddings or carpets requiring high bulkiness, by spinning hollow fibers in specific ranges of the take-off and quenching air stream speeds according to the modified spin-draw method.
CONSTITUTION: A fiber-forming thermoplastic polymer is melt spun through a spinneret comprising a plurality of orifices having a percentage of hollowness ≥ 25% and quenched by an air stream at a speed of Vg (m/min) perpendicularly to the yarn unsymmetrically, passed through a heating zone at 80°C or above, and drawn to give crimped fibers by a frictional force between air and take-off speed V (m/min) at the temperature gradient at once. The Vg and V satisfy the following formulas: V≤6000; Vg≥-1.67(V×10-3)+6.33; Vg≥0.13×V2×10-6-1.16(V× -3)+3.5; Vg≤0.17(V×10-3)+3.6.
