Abstract: PURPOSE: Provided is a method of manufacturing a polyester micro fiber with excellent evenness and spinning capacity which uniformly cools the molten polymer without being influenced by the intervening airflow, thereby minimizing the fluctuation thereof. CONSTITUTION: In the method of manufacturing a polyester micro fiber, a polyester polymer with an intrinsic viscosity of 0.640-0.670 is used, and the spray nozzle(2) for spraying the polyester polymer has spinneret holes of 100-300. The spraying of the polyester polymer is made at 275-290 deg.C by the amount of 0.10-2.0g/min hole. An air cooler(11) is directly placed under the spinneret to uniformly cool the sprayed polymer, and effectively intercept the intervening airflow. The air cooler is operated at 18-23 deg.C, and controlled in the airflow speed to be within 5-30m/min. An emulsion is applied to the cooled polymer while being distant from the spinneret by 750-1600mm downwards. The cooled and emulsified polymer is placed and heated between first and second rollers(5,6) at 70-90 deg.C, and drawn in a ratio of 1.3-4.0, being the speed difference between first and third rollers(5,7). The polymer is then re-heated at 110-130 deg.C by the third roller, and wound at 4000-6500/min.

Abstract: PURPOSE: Provided is a method for preparing a polyester triangular section yarn which involves high grade luster, excellent resilience, and soft tactile sensation with a uniform section face. CONSTITUTION: In a method for preparing a polyester triangular section yarn, a polyester polymer with an intrinsic viscosity of 0.640-0.671 passes through a special section-faced spinneret(2), and cooled while being applied with emulsion directly under the spinneret.

The number of the spinning holes is 24-144, and the amount of spinning thereof per minute is 0.20-4.5g/min.hole. The spinning of the spinneret is made at 280-290 deg.C, and the cooling is made by a cooling air(1) at 15-25 deg.C. The speed of the cooling air is 0.25-0.75m/s. The cooled polymer is heated between first godet rollers(4) at 75-90 deg.C, and drawn in a ratio of 1.4-2.0, being the speed difference between the first godet rollers and second godet rollers(5). The polymer is second-treated by the second godet rollers at 110-130 deg.C, and wound at 4000-6500m/min.
