The difference between the level of various quality indicators of the color spinning yarn and the natural color yarn: Because the fibers of the color spinning yarn are dyed, some of the fiber indicators are somewhat lower than those of the natural color fiber, especially for varieties with a color cotton ratio of more than 50%. The yarn breaking strength and evenness index are lower than that of natural yarn, while other quality indexes are improved to different degrees.
