Aiming at the problems of less research on the gradient colored yarn at home and abroad, and incapability of realizing the accurate control of yarn surface color and segmentation length during the production process, the mechanism of the control on the blending ratio by three?channel digital ring spinning drawing was studied. The forming principle of gradient colored yarn having the color gradient characteristics of hue, brightness and purity and spun from three rovings of magenta, yellow and green was analyzed, which were fed by three channels and drafted in gradient ratios. The sample gradient colored yarn is 27. 76 tex and has 10% color gradient of magenta, yellow and green. The appearance, yarn evenness and tensile mechanical properties of the sample gradient colored yarn were studied. The results show that the control on the blending ratio of magenta, yellow and green rovings by the three? channel digital ring spinning gradient draft achieves the color gradient characteristics of the gradient yarn. The breaking strength and yarn evenness of the gradient yarn are slightly lower than those of pure colored yarn with the same specification.
