Abstract
PURPOSE: To obtain extremely thin filaments useful for preparing a raising cloth, having a suede feeling with improved surface gloss at low cost, by spinning a thermoplastic synthetic resin through a specific spinneret at high speed.
CONSTITUTION: A thermoplastic synthetic resin (preferably polyethylene terephthalate, etc.) is extruded in molten state through a spinneret wherein several spining holes having a width 0.03W0.10 (preferably 0.05W0.08)mm, a length preferably ≥15 times as long as that of the width, and cross-sectional areas of spinning holes 0.007W0.033mm2 are bored, wound at a speed 3,000W4,500m/min, to give flat filaments of melt spinning having a flatness ratio 150W450% and single filament denier ≤0.5.
