干-湿纺聚丙烯腈/二甲基亚砜原液流变性能的研究

Study on rheological properity of dry-jet wet-spinning PAN/DMSO solution

通过对干湿纺聚丙烯腈 (PAN) /二甲基亚砜 (DMSO)纺丝流变性能的研究 ,确立了分子量、温度、浓度、剪切速率四种主要因素对纺丝原液黏度的影响 ,并通过正交实验分析法得出四因素影响的主次顺序 ,为控制PAN/DMSO溶液的流变性能 。

The rheological properity of dry jey wet spinning PAN/DMSO solution has been studied.The orthogonal experiment method substantiated the different effect degree of molecular weight,temperature, content of PAN,and shear rate.
