This method further regulated fiber morphology and structure，and significantly reduced the specific energy consumption for pulping at the same beating degree. When cellulase （ 40u/g ）was used for pre-treatment to assist pulping，at a beating degree of 3O ‘SR，the zero-span tensile strength of the bamboo pulp fibers decreased by 3.40kg/15 mm.However，the interlayer bonding strength of the paper increased to 160.9J/m2 ，the dry tensile index reached 15.1N⋅m/g ，and the softness value was 266 mN. When hemicellulase （ 40u/g ） was used for pre-treatment to assist pulping，at a beating degree of 30∘SR ， the zero-span tensile strength decreased by 3.96 kg/15 mm. However，the bonding strength increased to 166.4J/m2 ，thedrytensile indexreached19.3N·m/g ，and the softness value was 361 mN.
