Abstract
PURPOSE: To obtain a polyester filament yarn having uneven exhaustion, heat shrinkage, and thickness in the long direction, and uniform mixing state in any cross-section in the long direction as a whole, by drawing an undrawn polyethylene terephthalate yarn which is heat-treated under specific conditions.
CONSTITUTION: An undrawn polyethylene terephthalate filament yarn is heat- treated at 95W115°C under a tension of 0.5W0.8g/d, preferably 0.5W0.6g/d, and immediately drawn at 150W200°C at a draw ratio of 1.2W1.35 times the natural draw ratio.
EFFECT: A special polyester yarn having thick and thin parts at an interval thus obtained provides improved light and shade effects by one dyeing step.
