摘　　要：研究了低密度聚乙烯(LDPE)1I60A的流变性能,聚酰胺(PA)6/LDPE共混纤维的开纤剥离性能及其剥离前后形貌的变化。结果表明:LDPE 1I60A熔体黏度低,PA 6/LDPE熔体黏度比大,有利于提高PA 6/LDPE中PA 6的含量;LDPE 1I60A与PA 6共混后加工性能优良,"岛"相分布均匀,LDPE 1I60A更易从PA 6/LDPE共混纤维中被溶解抽出,有利于得到PA 6含量较高的超细纤维。The authors studied the rheological properties of low density polyethylene（LDPE） 1I60A, peeling properties of polyamide（PA）6/LDPE blend fiber and the variation of morphology before and after stripping. The results show that LDPE 1I60A melt having low viscosity and PA 6/LDPE melt with high viscosity ratio are favourable to increasing the content of PA 6 in PA 6/LDPE blend. The PA 6/LDPE blend has good processing properties and the island phase distribution is uniform. LDPE is dissolved out more easily from the PA 6/LDPE blend fiber, which is beneficial to obtaining superfine fiber with higher PA 6 content.
