Abstract

PURPOSE: In a process in which a polyester yarn melt extruded is cooled, drawn under heating and wound up at a speed of 3,000W8,000 m/min., a low shrinkage yarn with a dry-heat shrinkage of less than 80% at 160°C can be obtained by putting the drawn yarn, immediately after drawing, into contact with rolls heated at above 180°C for 0.01W0.02 second.
