Abstract
PURPOSE: An undrawn polyester yarn is irregularly pre-heated and made to run at a specific draw ratio to effect heat setting under tension, thus producing the titled yarn of low hot-water shrinkage, high durability and high-class appearance without reduction in strength.
CONSTITUTION: Undrawn yarn of polyester fiber 2 is unwound from the package P, fed through guide 1 to feed roller, 3, then irregularly heated on the cross section with the first heater 4. The irregulary heated yarn 2 is brought into contact with the friction substance 5 at a draw ratio lower than 1.1 times the natural draw ratio of the undrawn yarn to effect drawing and passed through the first draw roller 6 to give a thick-and thin yarn 2'. The resultant yarn is brought into contact with the second heater 7 higher at temperature than the first one under running to effect heat setting under tension, passed through the second drawing roller 8 and the guide 10, then made into package 9, thus giving the objective thick-and-thin yarn 2".
