纤维素液晶溶液的织构转变及纤维制备
Texture transformation and fiber preparation based on cellulose liquid crystal solutions
摘要
Abstract
In order to improve the breaking strength of cellulose fib ers, 4- (ω- (methylimidazolium) -6) -4'- (cyano)-(biphenyl) were dissolved in cellulose/AMIMCL solutions to generate cellulose liquid crystal solutions. The texture transformation properties were studied by orthogonal experiment, magnetic field and DSC, which high-strength cellulose fibers were prepared. The results showed that when the concentration of liquid crystal primer was 3％ and the temperature ranged from 70 ℃ to 80 ℃, and the magnetic field intensity changed from 70 A/m to 80 A/m, the texture of the liquid crystal was spherical. The best condition for the texture transformation was the temperature of 70 ℃, the magnetic field strength of 70 A/m, the temperature of 80 ℃ and the magnetic field strength of 80 A/m; the DSC results showed that the phase transition peak appeared at 70-80 ℃, and the peak was more sharp while the temperature range was narrower after the texture transformation. The breaking strength of cellulose liquid crystal fiber reached 3.17 cN/dtex, the strength increased by 40％, the fiber strength increased even more after texturing.关键词
