Abstract： In this study，the structure-property relationships between fiber aspect ratio，crystallinity，hydrogen bonding，and mechanical properties were elucidated，focusing on Ramie and Jute fibers from different origins and employing the hydrogen peroxide/glacial acetic acid delignification process. The results showed that the mechanical properties of Ramie fibers varied slightly depending on their origin. There were similar tensile strengths of （1 117. 0±55. 9） MPa for Ramie fibers（Zhejiang province）and （1 222. 0±61. 1） MPa for Ramie fibers（Ji‐ angxi province），but a better elastic modulus（（74. 3±3. 7） GPa）of Ramie fibers（Jiangxi province）. Compared to Ramie fibers，Jute fibers had the smallest tensile strength and elastic modulus of （139. 0±7. 0） MPa and （21. 1±1. 1） GPa，respectively，which was attributed to the higher crystallinity（ >78% ），stronger hydrogen bonding network（ >64% ），and higher aspect ratio（>1 900）of Ramie fibers.
