Abstract: In this study, 3 kinds of ramie decorticators simple, pull-back drawing and reverse drawing  were set up to check the effects of different peeling technologies on the fresh weight stripping percentage, color difference, single fiber strength and chemical components of ramie fiber. The results showed that the yield and quality of ramie fiber produced by different decorticators were significantly different. All kinds of fibers were nearly yellow, simple-peeled fiber was the brightest, while the color of reverse-peeled fiber was the reddest. There were no significant differences on the fresh weight stripping percentage between the simple and pull-back drawing decorticator, which was significantly lower than that of reverse drawing decorticator. However, the main reason for the higher fresh weight stripping percentage of the reverse drawing decorticator was the significantly higher total gum content (28.21%). There were significant differences in single fiber strength among 3 kinds of fibers, and the single fiber strength, from high to low, was simple peeled>pull-back peeled>reverse peeled (25.86 cN). In conclusion, the quality of ramie peeled by simple drawing decorticators was best, pull-back drawing decorticator was better than reverse drawing decorticator. The results provided a theoretical basis for decorticator selection.
