Abstract

PURPOSE: The titled special yarn that has U-shaped cross section and irregular changes in tensile characteristics, thermal shrinkage, dyeability and thickness along the fiber-length direction, thus giving fabrics with high stretcheability, thick-thin effect and charm of variation.
CONSTITUTION: A polymer is extruded through a spinneret having spinning hole units in which round-cross section holes of 0.10W0.30mm diameter are arranged on the apexes of penta- to octagon of 0.4W1.0mm diameter circumcircle and fused immediately under the spinneret to prepare undrawn yarn of U-shaped cross section. The resultant undrawn yarn is drawn at a 0.7W1.10 natural draw ratio to produce the objective yarn in which each constituent filament has uneveness in thickness in the lengthwise direction where the cross section ratio of the thick filament part to the thin part is 1.20W3.00 and the filament count of the thick filaments is less than 80% of the total, the length of the thick parts is 0.5W5cm and the number of the thick parts in each filament is 10W30 per 1 meter.
