| 摘 要： | 研究了湿法和于湿法纺制异形聚丙烯腈(PAN)纤维过程中拉伸对纤维截面形状的影响。结果表明:喷丝头拉伸对湿法纺制的PAN初生纤维截面影响明显,随着喷丝头拉伸倍数的增大,纤维异形度逐渐增大;喷丝头拉伸对于湿法纺制的纤维截面形状和异形度影响较小;沸水拉伸对二者的纤维截面形状和异形度几乎无影响。

| Abstract: | The effect of stretch on the cross-section shape of polyacrylonitrile (PAIN) fiber was studied during the process of wet spinning and dry wet spinning. The results showed that the jet-stretch had an evident effect on the cross-section shape of PAN fiber prepared by wet spinning process, and the profile degree of the fiber was raised gradually with the increase of jet-stretch ratio. The jet-stretch had a slight effect on the cross-section shape and the profile degree of PAN fiber prepared by dry wet spinning process. The boiling water stretch had little effect on the cross-section shape and profile degree of the fillers prepared by these two processes. |
