氨纶纱加工、性能研究的现状与发展

The Study on the Processing and Performance of Polyurethane Fiber Yarn

氨纶是近年来快速发展的高弹性合成纤维,其延伸和回复性能使服装更合体、更舒适。文章介绍了氨纶纤维的结构、性能和生产发展状况,分析了各类氨纶纱加工原理及其性能,阐述了氨纶热定形加工的机理及工艺,讨论了含氨纶纺织品的染整工艺和发展趋势。

Polyurethane fiber yarn is a high-elastic synthetic yarn that hasbeen developing rapidly over the past few years. The extensibil-ity and recoverability of such yarn make garment better fit andmore comfortable. The article gives a systematic introduction tothe structure, performance and production of polyurethane fiberand analyzes the processing principles and characteristics ofvarious polyurethane fiber yarns. It also introduces the polyure-thane fiber heat-setting principle and process and discusses thedyeing and finishing process and development trend of polyure-thane fiber-contained textiles.
