The invention discloses a method for producing novel colored spun yarn. The method includes the steps that three kinds of raw material fiber different in color are manufactured into half-drawn slivers through cotton plucking, cotton opening, coiling, cotton carding, primary drawing and secondary drawing in sequence, and the half-drawn slivers are a main colored sliver, a first auxiliary colored sliver and a second auxiliary colored sliver respectively; the main colored sliver, the first auxiliary colored sliver and the second auxiliary colored sliver are manufactured into yarn together through the working procedures of final drawing, roving, spinning and spooling, the final drawing working procedure is carried out in a drawing frame device, and the drawing frame device comprises a cotton feed roller and a drafting region. When the drawing frame device is used for the yarn spinning working procedure, the main colored sliver, the first auxiliary colored sliver and the second auxiliary colored sliver are different in color, distinct color contrast exists generally, and therefore the yarn and fabric obtained after the roving and spinning working procedures are carried out present a style entirely different from that of traditional fabric.
