Abstract:This study systematically evaluated the mechanical properties of sisal pulp fibers under different alkali charges during the NaOH-AQ cooking process. It also analyzed the fiber morphology, microfibril angle, crystallinity, and lignin content to explore their synergistic effect on the mechanical properties of individual fibers. The results showed that as the alkali charge increased from 12% to 30%, the modulus of sisal pulp single fibers decreased from 12.6 GPa to 6.99 GPa; the flexibility index increased from 0.54×1017/（N·m2）to 3.15×1017/（N·m2）; the cell wall hardness reached its maximum value of 449.2 MPa at an 18% alkali charge, and the zero-span tensile index of the fibers reached its maximum value of 177 N·m/g at a 15% alkali charge. Keywords: sisal pulp, alkali concentration, mechanical properties。
