THE COOLING APPARATUS FOR MANUFACTURING OF POLYESTER FILAMENT DRAWN YARN HAVING THICK FINENESS AND THE MANUFACTURING METHOD OF POLYESTER FILAMENT DRAWN YARN HAVING THICK FINENESS USING THEREOF

摘要

The present invention is a fixed threaded rod is formed on the surface, a small hole is formed by a capping hole location cooling to form a different size filter, and the cooling air discharging portion consisting of the upper cap and the lower holder for fixing the cooling filter; The lower holder is interpolated and the first fuel supply device consisting of annular protruding on the upper outer periphery is formed, the cooling air is emitted's contact in order not to influence the guide has a formed ceramic having a cooling air supply pipe to cool the incoming direction air supply; Is composed of a fixed rod fixed to the bolt to form the cooling air supply and the discharge portion connected to the fixed upper jidoe rod cap, cooling filter, and the lower holder, is inserted in the order of the cooling air supply is fixed to the fixing rod fixing bolts, fixing thread is formed using a state fineness filament for manufacturing polyester filament cooling device and the cooling device, characterized in that to position the rod in the middle, but the spinning nozzle and the temperature of the cooling air by 18 to 30 , wind speed of the cooling air is 20 to 90m / and a minute, immediately below the spinneret 500 to give primarily from the emulsion and 1200mm, 2500 to give an emulsion at 4000mm and second drive, the first roller and the second roller heated at a stretching temperature of 80 to 95 , and the first and drawn at a draw ratio of roller speed of the third roller and the fare of 2.1 to 6.0, the third roller in a temperature range of 110 to 145 after heat treatment using the method of winding at a speed of 3000 to 5000m / min to 3000 to 5000 The m / single yarn fineness in the final take-up speed of min 5 denier to 50 denier, the strands are of 1 to 40 strands of state fineness hameuroseo producing a polyester filament filament, and uniform and stable cooling effect of the air flow to minimize interference and evenness However if there was fluctuation is excellent and you get this excellent workability radiation effects.
