The invention relates to a manufacture method of spinning industry materials, in particular to a manufacture method of corn protein viscose staple fibers, which realizes the spinning through utilizing corn protein spinning solution and cellulose sulphonate solution to carry out static mixing and spinning injection. The manufacture method mainly comprises the steps of A, corn protein liquid preparation; B, corn protein liquid and viscose liquid blending; C, spinning; D, solidification and curing; and E, post treatment. Fiber beams are subjected to cutting, acid washing, desulfuration, water washing, acid washing, water washing, oiling, dehydration and drying, and then, corn protein viscose staple fibers are obtained. The manufacture method has the advantage that the corn protein viscose staple fibers manufactured by raw materials according to the proportion, the temperature, the concentration and the process flow in the method have soft filament strips and bright yellow color and luster. Compared with the prior art, the production method for producing the corn protein viscose filaments has the advantages that the process is simple, and the operation is convenient.
