| 摘 要： | 采用双向拉伸的方法制备了聚醚砜中空纤维,探讨了工艺条件对聚醚砜中空纤维取向度和水通量的影响。结果表明:随着纺丝速度的提高,纤维的取向度上升,水通量下降;在总拉伸倍数不变的前提下,随着凝固浴拉伸倍数的提高,纤维的取向度和水通量都减小;随着填充液压力的提高,纤维的取向度下降,水通量增加;随着凝固浴中二甲基亚砜含量的提高,纤维的取向度先增大后减小,出现了一个最大值,水通量先减少后增加,出现了一个最小值。

| Abstract: | Polyethersulfone hollow fiber was prepared by biaxial stretching method.The effect of process conditions on the ori- entation degree and water flux was discussed for polyethersulfone hollow fiber.The results showed that the orientation degree of the fiber was raised and the water flux was reduced when the spinning speed was increased;The orientation degree and the water flux were decreased at a given total stretch when the coagulation bath stretch ratio was increased;The orientation degree was re- duced and the water flux was raised when the filling liquid pressure was increased;And the orientation degree was increased to a maximum and then decreased and the water flux was decreased to a minimum and then increased when the content of dimethyl sulphoxide was increased in the coagulation bath. |
