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 0.45-0.75, is melt spun through a spinneret with orifices satisfying the formulas 1-5 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 0.3- 1.0 denier in great demand industrially stably without requiring expensive composite spinning devices.

Abstract: PURPOSE:To obtain spun yarn-like bulky filament yarns capable of giving woven or knitted fabrics having stiffish and crispy feelings, by letting two kinds of filament yarns of different filament deniers contact a heating element under specific conditions, and by intertwining the yarns in a fluid turbulence zone.

Abstract: PURPOSE:Manufacture of thick-and-thin polyester yarns with less fluffing when textured, by partial stretching of undrawn yarns having a specific birefringence to develop thick and thin partions, followed by restretching under heating to such an extent as not to destory these uneven, portions.
