Abstract

PURPOSE: To obtain a medium ultra-fine filament yarn of good quality stably according to the ordinary melt spinning method, by spinning a sunthetic linear thermoplastic polymer under specific conditions of a spinneret, output, and spinning tension.
CONSTITUTION: A synthetic linear thermoplastic polymer, referably polyethylene terephthalate having an intrinsic viscosity of 0.45W0.75, is melt spun through a spinneret with orifices satisfying the formulas 1W5 at an output satisfying formulas 6 and 7 under a tension satisfying formula 8 and winding conditions satisfying formula 9 to give a medium ultra-fine filament yarn having a fineness per filament of 0.3W 1.0 denier in great demand industrially stably without requiring expensive composite spinning devices.
