Abstract
PURPOSE: To obtain the titled filamentary yarns having thick and thin parts in the long direction thereof, by drawin ghighly oriented undrawn polyester multifilamentary yarns at a low draw ratio, turning filament after drawing large- diameter rollers, and heat-treating the filamentary yarns under no tension.
CONSTITUTION: Highly oriented polyester multifilamentary yarns 1 having a double refraction of 20×10-3W70×10-3 are drawn at a low draw ratio between feed rollers 2 and large-diameter rollers of stepped rollers 6 with hot pins 3 to give yarns having thick and thin parts. The resultant yarns are then passed through the large-diameter rollers of the stepped rollers 6, return guides 4 and 4' heat-treating apparatuses 5 and small-diameter rollers of the stepped rollers 6 one after another, heat-treated under no tension and then wound onto winders 7 to give the aimed filamentary yarns.
