| Abstract: |
| Based on the results of orthogonal experiment of kraft cooking of acacia wood as well as beating and paper-making experiments of the resultant pulp, the comprehensive coordinate method was applied to optimize cooking conditions of acacia wood. The results showed that at the conditions of alkali charge(Na2O)15%, sulfidity 30%, liquor to wood ratio 1∶4, the max temperature 165℃, time to the max temperature 1 h, time at the max temperature 2 h, acacia wood kraft pulp with yield 52.25%, Kappa number 17.9, viscosity 987.3 mL/g, breaking length 9.32 km, tensile index 93.6 N·m/g, tearing index 10.0 mN·m2/g and bursting index 5.34 kPa·m2/g was obtained. |
