This invention belongs to the field of spinning technology and relates to a coarse denier, low-pore polyester medium-oriented yarn and its production method. The production method involves extruding the melt from the spinneret's orifices, then sequentially passing through a windless zone, a transition zone, and a side-blown cooling zone. The windless zone and transition zone are the upper and lower sections of the same cylindrical component, respectively. Different spinnerets correspond to different cylindrical components, and the cylindrical components do not directly contact the spinnerets. The upper section of the cylindrical component has no through holes in its wall; the lower section has through holes on its wall to guide ambient air into the interior of the cylindrical component and prevent turbulence inside. The length of the windless zone is 5-6 cm, and the length of the transition zone is 6-10 cm. The percentage difference in wind speed between the side-blown cooling zones is no higher than 10%, where the percentage difference is calculated as (maximum wind speed - minimum wind speed) / maximum wind speed × 100%. This production method achieves uniform cooling of the inner and outer layers, resulting in coarse denier, low-pore polyester medium-oriented yarn with advantages such as high breaking elongation.
