Method for preparing anti-mosquito regenerated cellulose fiber

The invention discloses a method for preparing an anti-mosquito regenerated cellulose fiber. The method is concretely carried out according to the following steps: 1, crushing a picked cattail fiber, and purifying and activating the fiber; 2, weighing raw materials according to the following formula: 16%-18% of cattail cellulose, 2%-4% of common cellulose, 4%-8% of natural anophelifuge and the balance being a cuprammouium solution, and then preparing a spinning solution; 3, carrying out wet spinning by virtue of the spinning solution prepared in the step 2; and 4, carrying out post-treatment of drafting, oiling, baking and the like on a primary fiber prepared in the step 3. By the method disclosed by the invention, the defects that an existing anti-mosquito material is low in anti-mosquito rate, poor in durability, and not washable are solved.
