Using melt spinning process route, we has successfully developed the 889 dtex/192 f super-coarse denier polyester DTY. The results indicated that the lower temperature of the melt conveying, spinning temperature of 284℃, cooling method with quench air plus Arc Board, beaming in 1 500 mm, oiling choosing appropriate nozzle （ Jingci and other large nozzle）, etc. were suitable for spinning the coarse denier filament. The product quality is stable, the postprocessing and weaving effect is good.
