摘要
探讨了扁十字形截面涤纶短纤维的生产工艺,得到了适宜的工艺参数:冷却风速度1.2 m/min,冷却风高度60mm,纺丝温度292℃,纺丝速度1 100m/min,总拉伸倍数3.08,卷曲温度80℃,上油率约0.2%, 紧张热定型温度160℃,可生产成品异形度大于45%,各项性能指标合格的产品。
The production technology of flat cross polyester staple fiber was discussed. The appropriate process parameters were as followed: quenching speed 1.2 m/min and height 60 mm, spinning temperature 292℃ and speed 1 100 m/min, total draw ratio 3.08, crimping temperature 80℃ , oil pick-up about 0. 2% , tension-setting temperature 160℃. The produced fiber bad profile degree above 45% and exhibited qualified properties.
