| Abstract: |
| The effect of enzyme pretreatment on the properties of Salix Psammophila P-RC APMP was studied. The effects on optical properties of the pulp from pretreated Salix Psammophila by xylanase, laccase medium and laccase /xylanase were all different, the breaking length of the pulp reduced by 9.5%, 0.8% and 6.7%, and the bursting index reduced by 11.0%, 4.1% and 13.8%, the tearing index improved by 8.3%, 8.0% and 1.3% respectively compared with the pulp from unpretreated new material. X-ray diffractometer analysis indicated that the crystallinity of the cellulose reduced after enzyme pretreatment. |
