| 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 （Jiangxi 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. |
