摘要
从"8"字形喷丝板的设计、纺丝箱体温度、组件压力、冷却条件、纺丝速度等方面对222 dtex/30 f"8"字形涤纶高取向丝(HOY)的生产工艺进行研究。结果表明,纺丝温度控制在283~285℃,组件初始压力控制在12 MPa左右,侧吹风风速控制在0.6 m/s、风温控制在20℃,卷绕速度控制在4700 m/min,牵伸比控制在1.09,第一热辊速度控制在4300 m/min、温度控制在85℃,第二热辊速度控制在4700 m/min、温度控制在135℃,纺丝状况稳定,截面异形度高、规整度好,产品品质优良。
The technological conditions of 222 dtex/30 f"8"shaped polyester HOY were studied from the"8"shaped spinneret design,spinning box temperature,component pressure,cooling conditions,spinning speed and so on.The results show that the spinning temperature is controlled at 283~285℃,the initial component pressure is controlled at 12 MPa,the wind speed of the side blowing cooling air is controlled at 0.6 m/s,the wind temperature is controlled at 20℃,the winding speed is controlled at 4700 m/min,the draw ratio is controlled at 1.09,the GR1 speed is controlled at 4300 m/min,temperature is controlled at 80℃,GR2 speed is controlled at 4700 m/min,GR2 temperature is controlled at 136℃,the spinning condition is stable,the cross-section profile is high,the regularity is good,and the product quality is excellent.
