Abstract: Increasing the added value of chemical fibers is an eternal research subject, especially under the background of conventional chemical fiber production in China suffering from surplus capacity. How to increase the added value and realize sustainable development is a common problem concerned by both the industry and enterprises. Currently, there are many ways to add value to fibers, mainly including making innovations in process and technology, realizing energy-saving and environment protection and reducing costs as well as developing serial, high-performance, multi-functional, nanometer-grade, smart and personalized products. To address this topic, the paper analyzed the development and application of valueadded fibers both at home and abroad and also discussed the deve loping trends of such fibers.

Key words: value-added fiber; high-performance; functional; nano-grade; smart; personalized
