Abstract
PURPOSE: To obtain the title yarn having improved strength, transparency, gloss, and hygroscopicity at a low cost, by melt spinning a blend of specific polymers, and by drawing a taken-up yarn with a specific moisture content and contact pressure.
CONSTITUTION: Thermoplastic polymers having the second-order transition point of at least 100°C comprising about 0.2W2.0wt% of acrylonitrile-containing polymers are blended and melt spun into filament yarns, which are oiled with about 4W9%, preferably 5W8%, of moisture, and taken up under a drum contact pressure of 0.6W5.0kg, preferably 2.0W4.0kg, and drawn. The winding density of the undrawn yarn is preferably about 0.65W0.85g/cm3. According to the method, the following effects are produced: Increased sprinning speed suppression of longitudinal yarn swell, stabilization of package forms, increased widing density, enlarged packages, improvement in drawing operating efficiency, and sharp increase in drawing speed.
