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.
