-phenylene terephthalamide) (PPTA) Fiber is widely used for its excellent mechanical properties
thermal stability
etc. However
this magic fiber has not been realized mass production in China due to various difficulties. This review focuses on the characteristics and technical challenges of low temperature polycondensation
liquid crystal spinning and solvent recycling for mass production of PPTA fiber. Further
the development of the research on the thinner PPTA fiber especially the PPTA nano-fiber is briefly commented.
