Abstract
PURPOSE:To obtain the titled special yarn having excellent feeling and shading effects, by extruding polyester filaments through spinning hole groups of a specific spinneret, fusing the resultant filaments just after extrusion, then winding the fused filaments at a specific speed and drawing the wound filament yarn at a specific ratio. CONSTITUTION:Polyester filaments are melt extruded through spinning hole groups of a spinneret having circular spinning holes with 0.10-0.30mm diameter arranged at the apexes of a tetragon, pentagon, hexagon, heptagon or octagon on the circumference with 0.4-1.0mm diameter and then fused just under the spinneret just after the extrusion to prepared an undrawn yarn of U-shaped cross section. The resultant undrawn yarn is subsequently wound at 1,000m/min speed and drawn at 0.7-1.10 times based on the natural draw ratio to afford the aimed special yarn having U-shaped cross section and irregular strength and elongation, heat shrinkage and dyeing characteristics, uneven thickness, etc., in the fiber direction.
