| Abstract: | The technology of sea-island fiber using local made water-soluble PET chip was studied. The processes of drying temperature, spinning temperature, cooling condition, drawing and twisting were discussed emphatically. The key parts technology and management was described. The processes of POY were precrystallization temperature of COPET 90~100 ℃, dry temperature 130~140 ℃, initial pressure of spinneret pack 8 MPa, sea-idea ratio 29∶71, cooling blow velocity 0.45~0.50 m/s, cooling blow temperatur 18~20 ℃. |
