Abstract

PURPOSE: To obtain fancy yarns having partial differential degrees of exhaustion random in the long direction, by drawing doubled two types of highly oriented undrawn polyester filament yarns having different elongations at break under specific conditions.
CONSTITUTION: Two types of undrawn polyester filament yarns having an elongation at break of 70W200%, preferably 100W180%, and a difference in elongation at break ≥10% are doubled, brought into contact with an unheated pin or edge and cold drawn at a draw ratio to give the elongation at break of the low-elongation component of 20W50%, then preferably false twisted at an overfeed ratio of -10W 3%. The undrawn yarns are obtained by spinning polyester at a high speed of 2,000W5,000 m/min or by spinning at a low speed and by preliminarily drawing undrawn yarns thus obtained.
