| 摘 要： | 研究涤纶纤维微观结构对纤维性能的影响。选用不同截面形状、线密度、功能性的微孔结构阳离子改性涤纶与未改性涤纶作对比实验。从纤维的密度、吸湿性、强伸度、染色性能等宏观数据分析改性后纤维的微观结构对其性能的影响。结果表明:微孔结构阳离子改性涤纶由于通过3,5-双苯磺酸钠(SIPE)和聚乙二醇(PEG)的化学改性,纤维中添加了一定的亲水基团且结晶度有所降低,纤维回潮率有所升高,同时纤维的微孔结构的表面形态使纤维的密度、强度和初始模量有所下降,纤维改性后可以在常压下用分散染料进行上染。

| Abstract: | In order to study the effects of the microstructure of the fiber to the properties,the different sectional shape,linear density,functionality of microstructure cationic modification polyester are used to do contrast test,analyzing the effect of microstructure of fiber that was modified on density,moisture absorption,strength and the dyeing properties and so on.The result shows that when the hydrophilic group is added,the crystallinity decreases and the official moisture content rises through the chemical mo... |
