Juncao regenerated cellulose fiber prepared by ionic liquid method and preparation method of Juncao regenerated cellulose fiber

The invention belongs to the field of chemical spinning, and particularly relates to an ionic liquid method Juncao regenerated cellulose fiber and a preparation method thereof.The preparation method comprises the steps that ionic liquid and nickel chloride are added into Juncao pulp and evenly mixed to obtain a mixed material, the mixed material is subjected to swelling, dissolving, defoaming and dry-jet wet spinning forming and then dried, and the Juncao regenerated cellulose fiber is obtained. A catalyst nickel chloride is added in the process of dissolving cellulose by ionic liquid to reduce the viscous state degree of a Juncao cellulose dissolving solution, and a mixed aqueous solution of ethanol and glycerol is selected as a coagulating bath of a dry-jet wet-spinning forming process to improve the dry stretching performance of Juncao cellulose fibers; the invention optimizes the existing ionic liquid method cellulose fiber preparation process, and provides an ionic liquid method suitable ...
