Abstract
PURPOSE: To obtain a filament yarn having undrawn and drawn parts, light and shade and a little variation in quality, by keeping an undrawn polyester filament yarn under a wound state at a specific temperature, and by drawing the yarn under specific conditions.
CONSTITUTION: An undrawn polyester filament yarn having a double refraction of 0.015W0.06 is kept at a temperature 10°C or more lower than the second-order transition point to increase the natural drawn elongation of the yarn. The yarn is then drawn below a drawn ratio at which the tension begins increasing, (preferably below the natural draw elongation), and preferably neck-drawn so that the total draw ratio may exceed 0.55 of the maximum draw ratio. Preferably, the yarn is false twisted at the time of neck-drawing.
