Abstract

The effects of pretreatment by xylanase on properties of salix psammophila KP were researched in this paper.The effects of different dosage of enzyme on fibre morphology and paper properties were studied. The results showed that pulp properties can be improved by pretreatment with xylanase.The fibre average length increases after pretreatment, fines content decreased and brightness and physcial properties improved. Brightness and physcial properties improved and scattering coefficient,absorption coefficient and opacity decreased with dosage of enzyme increasing. But brightness and physcial properties decrease and scattering coefficient,absorption coefficient and opacity increases slightly when the dosage of enzyme beyond 10IUg-1.X-ray diffractometer analysis indicated that the degree of crystallinity of fibre increased after xylanase pretreatment.
