摘要
通过建立数学模型对微孔聚烯烃中空纤维膜原纤的垂直向上纺丝过程进行了数值模拟分析 .文中将向上纺丝模式与向下纺丝模式进行分析并对实验的结果比较 ,从而得到了垂直向上纺丝操作的特点及产生这些特点的原因 .
This paper gives a numerical simulation analysis to the upward spinning process of polyolefin hollow fibre microporous membrane by setting up mathematical model,obtains the characteristics of operation of upward spinning and its cause by analysing the upward and downward spinning process,comparing the two experimental results.
