Abstract

PURPOSE: To obtain a completely continuous high grade superfine multifilament yarn having improved uniformity and coherency free from cohesions, broken filaments, and fluffs, by melt spinning a high polymer at a low output and a high take-off speed under specific conditions.
CONSTITUTION: A high polymer is melt extruded from the spinneret 1 at an output Q per orifice ≤0.15g/min into a filament yarn, which is oiled by the unit 4, taken off by the rollers 5 and 6 at a speed ≥18,000Qm/min, then entangled by the interlace or false twisting nozzle 7, and taken up by the winder 9. The orifice diameter is ≤0.20 mm, and the spinneret has the orifices to satisfy the following relation: 0≤K=(D2-D1)/D2 ≤0.25. The filaments 2 are bundled by the fulcrum guide 3 at the following position: 3≤ a/D2≤40. Preferably, the roller 5 is located at a position to satisfy the following relation: 400≤ b≤ 2500 (mm).
