Color blended rotor spun yarn mixing with different methods were spun. Three blending methods were used, onepassage of drawing, three passages of drawing and rovings during multi-channel spinning. Multi-channel spinning ismodified on rotor spinning machine, which is implemented by a novel mechanical system specially designed toincorporate three separate feed rollers side by side and controlled by servo motors with PLC. Using this new method,blend ratio of yarn can be controlled and realized by asynchronous drafted rovings. 37 type of color blend yarn wereproduced with different blending ratios. And each yarn was intercepted with 5 cross sections and a total of 185cross-sectional images were taken. Hamilton index of different colored fibers were calculated of the each type of yarns.And sum of absolute values of Hamilton index were got to demonstrated fibers blending effect in yarns cross sections.All the Hamilton index of the yarns prepared by the three above mentioned methods were all around 5, much below 20.The results showed that regardless of blending method used, the blending effects of rotor spun yarns were all very good.
