摘　　要：为改善聚丙烯纤维的染色性能,使其达到阴离子染料可染的效果,设计合成了一种主链是阳离子型的聚离子液体,对其与聚丙烯共混体系的相容性进行研究;将共混体系通过熔融纺丝得到阴离子可染聚丙烯纤维,借助纱线强伸度仪研究了纤维的力学性能,并通过染色实验对纤维的染色性能进行分析。结果表明:聚丙烯与聚离子液体共混体系具有良好相容性,聚离子液体的加入使聚丙烯的结晶度和取向度降低,从而使得其改性聚丙烯纤维更有利于与染料结合;改性聚丙烯纤维的上染率达到17.0%,染色深度值达到5.4503,且改性纤维的断裂强度为4.4 cN/dtex,符合纺织加工的要求。In order to prepare anionic dyeable polypropylene fiber,a type of cationic polyionic liquid was designed and synthesized,and its compatibility with the polypropylene blend system was studied.The blended system was spun into yarns by melt spinning method,and its mechanical properties and dyeing properties were investigated.Results show that the blending system of polypropylene and polyionic liquid has good compatibility.The addition of polyionic liquid reduces the degree of crystallinity and orientation of polypropylene,which makes the modified polypropylene fiber more favorable to combine with the dye.Dyeing experiment on the modified fiber showed that the dyeing rate and the dyeing depth of the fiber reaches 17.0%and 5.4503 respectively.The breaking strength of the modified fiber is 4.4 cN/dtex,which meets the requirements for textile processing.
