【Abstract】 The effect of coagulation bath temertature in N-Methymorpholine-N-Oxide (NMMO) process on the super-molecular structure, mechanical properties and the maximum spinning speed of Lyocell biber is investigated. The results show that the maximum spinning speed and the extension at break of Lyocell fiber increase, while the crystallinity, amorphous orientation, tenacity and initial modulus of Lyocell fiber decrease as the coagulation bath temperature is increased.更多还原
