A colored-segment yarn production method, a produced composite yarn, and a produced textile. The production method comprises the following steps: (1) combining one or multiple raw yarns to weave an open width knit fabric on a weft-knitting knitting machine; (2) performing, using a printing device and according to patterns, printing processing on the open width knit fabric woven in step (1); (3) performing printing, steaming, color fixing, washing, emulsification, water removal, and drying on the open width knit fabric acquired in step (2), so as to acquire a printed grey cloth; and (4) disintegrating, by utilizing the disintegration properties of a weft-knitted fabric and by means of winding and pulling by a yarn winding machine, yarns in the printed grey cloth acquired in step (3), and winding the yarns into one or multiple yarn cones having a segmented dyeing effect, thereby completing the processing of the colored-segment yarns. The colored-segment yarn production substantially eliminates the need for manual operation, and is easy to implement, thereby greatly improving productivity. In addition, easily-designed patterns and a large variety of types enable the produced composite yarns and textiles to have novel product styles, stable properties, and high yield.
