| Abstract:This study employs the peroxide/acetic acid delignification method to explore the relationship between the mechanical properties of fibers and their chemical components, particle size, crystallinity, hydrogen bonding, etc., using fibers from two jute and one hemp species as subjects. The results show that there are slight differences in mechanical properties among fibers from different jute origins. Compared to hemp fibers (139 ± 7.0 Mpa, 21.10 ± 1.1 Gpa), jute fibers from Jiangxi Province (1222 ± 61.1 Mpa, 74.32 ± 3.7 Gpa), which have higher crystallinity, a stronger hydrogen bonding network, and a higher aspect ratio, exhibit superior mechanical properties. This study provides theoretical support for the preparation of cellulose materials with high mechanical properties. |
