Abstract
PURPOSE: To obtain the title filament yarn according to the direct spinning and drawing method, by drawing and thinning a filament yarn extruded through a specific spinneret at different outputs per orifice under specific conditions, without using rolls for regulating the draw ratio.
CONSTITUTION: A synthetic linear thermoplastic polyester, particularly polyethylene terephthalate (co)polymer, is melt extruded through the spinneret 1, wherein a plurality of orifices 11 with different outputs per orifice and/or cross-sectional shapes are grouped and arranged separately by outputs and/or cross-sectional shapes into a filament yarn. The yarn is then cooled to 80°C, hot-drawn, and thinned under such conditions as to satisfy the yarn deformation ratio (a) between the yarn speeds before and after the heating atmosphere of the formula [V is the yarn toke off speed after drawing and thinning (m/min); V1 is the running speed of the yarn just before the heating atmosphere (m/min); a is V/V1].
