PURPOSE: A method for preparing a polyester micro filament yarn is provided, to obtain a polyester micro filament yarn having good characteristics and dyeability and to improve the workability. CONSTITUTION: A polyester micro filament yarn is prepared by melting emitting the polyestermicro filament yarn whose single strand fineness is 1.0 or less Denier and whose single strand number is 40 or more at an emission rate of 3,000 or more m/min; cooling it; passing it through a heating region, and dispersing the separate filament to the direction of circumference by using an inverse corn-shaped heater (7) (the length: 0.6-0.8 m) containing a ceramic circular plate (7'), thereby to allow it to be heated uniformly; oiling it within 2.0 m from the emitting entrance; and air-bridge treating it; |
