Specifically, after chitosan is added into an alkali solution of allantoin, blending spinning is performed with a viscose spinning solution to prepare the regenerated cellulose fiber. According to the present invention, chitosan is dissolved in the allantoin alkali solution, solubility of chitosan in the alkali solution can be greatly improved due to a characteristic that allantoin and chitosan are similar in structure, and a defect that various performances of traditional chitosan 10 viscose fiber prepared by directly blending chitosan powder are lowered is avoided. Meanwhile, distribution of chitosan in the fiber can also be improved, and an antibacterial effect of the fiber and durability of antibiosis can be improved easily. 12
