摘要: Wheat straw cellulose (WSC) was simply isolated by delignification and hemicellulose-removal processes, then dissolved in five non-derivatizing solvents, including N, N-dimethylacetamide /lithium chloride, N-methylmorpholine-N-oxide, 1-butyl-3-methylimidazolium 1-allyl-3-methylimidazolium chloride 1-ethyl-3-methylimidazolium acetate, to prepare regenerated fibers with wet spinning method. The results showed that WSC could be completely all of the chemical structure thermal stability were similar. However, viscosity solutions, morphology mechanical strength highly depended on type solvents.
