Abstract

PURPOSE: Polyester is melt spun using a specific spinneret at a specific throughput and taking-up speed to produce completely continuous fibers of fine denier which are high-quality, free from yarn-breakage, fluffing and fusing.
CONSTITUTION: Polyester is melt spun using a spinneret in which the nozzle diameter is less than 0.2mm and the nozzle arrangement satisfies equation: (D2-D1)/ D1=0-0.25, where D1 and D2 are minimum and maximum nozzle arrange diameters respectively, at a throughput Q of less than 0.15g/min per nozzle and a taking- up speed of over 18000Qm/min. At this time, the gas that flows at a ratio of V1/2 [5+(6H-300)1/2/16.5WV1/2[(70H+3500)1/2-30]/16.5 is sucked from the outer periphery toward the center at the position beneath the spinneret within 10cm to control the temperature of the atmosphere near the spun yarn to (50η-63)L2+ (331-200η)L+250η-70W130+(5-L), when L is smaller than 5 or to lower than 130°C, when L is not smaller than 5.
