Abstract: | The development and production of PET/COPET islands in the sea bicomponent POY fiber are studied.The product quality is good when the precrystallization temperature of COPET is 135~145 ℃,the drying temperature is 140~150 ℃,the drying time is 10~12 h,the spinning temperature is 275~278 ℃,the cross air blow speed is 0.3~0.4 m/s,the spinning speed is 3 000~3 200 m/min,the superfeed ratio is 8%~12%.The firsts percentage of afterprocessing product DT can reach 94%. |
