| Abstract: | Sisal fibers were modified by alkaline treatment and alkalation treatment, surface morphology structure and mechanical properties of sisal fiber were studied, and the effect of treatment on fracture of sisal fibers was researched. The results showed that alkaline treatment and alkalation treatment etched the surface of sisal fibers. The alkalation treatment changed the fracture of sisal fibers to be fibrillation. While tensile strength of fibers were improved by 9 % and 21 % , tensile elongation of fibers were improved by 63. 4 % and 122. 2 % after treatment. |
