IONIC LIQUID METHOD-BASED JUNCAO REGENERATED CELLULOSE FIBER AND PREPARATION METHOD THEREFOR

The present invention belongs to the field of chemical textiles, and particularly relates to an ionic liquid method-based Juncao regenerated cellulose fiber and a preparation method therefor. The preparation method comprises: adding an ionic liquid and nickel chloride into a Juncao pulp; uniformly mixing same to obtain a mixture; and subjecting the mixture to swelling, dissolving, defoaming and dry-jet wet spinning formation and then drying same to obtain Juncao regenerated cellulose fibers. The present invention adds a catalyst, i.e. nickel chloride, during the process of dissolving cellulose in the ionic liquid so as to reduce the viscosity of the Juncao cellulose solution, and selects a mixed aqueous solution of ethanol and glycerol as a coagulation bath for the dry-jet wet spinning formation process so as to improve the dry elongation property of the Juncao cellulose fibers. The present invention optimizes the existing preparation processes for an ionic liquid method-based cellulose fiber, and provides th
