Abstract

PURPOSE: Undrawn yarn with natural draw strain is subjected to 2-stage drawing to produce the titled yarn that has irregularly uneven part in the lengthwise direction, undrawn part remaining at a specific ratio, thus having silk-like natural patterns free from crimps with high durability.
CONSTITUTION: Undrawn yarn of polyester multifilaments with a natural draw strain (εND) of more than 0.35 1 is subjected to the first drawing in the drawing zone L1 between rollers R1 and R2 at room temperature to 90°C at a draw ratio of less than 1+εND. Then, the second drawing is effected the drawing zone L2 between rollers R2 and R3 under heating with the plate heater PH at 85W170°C at a draw ratio exceeding 1+εND to produce uneven yarn that has irregularly uneven part, 0.7W7U%, uneven parts consisting of more than 45% drawn filments 6 and less than 55% undrawn 7 or partially drawn filaments 8 where the undrawn filaments are less than 30% in the uneven parts and the uneven parts containing undrawn filaments in less than 60% based on the total uneven part.
