Abstract
The xylanase from Leveking was used in the experiment of bleached Soda-AQ pulp of fast-growing poplar. The suitable conditions of the xylanase from Leveking were obtained in the pretreatment of the Soda-AQ pulp of fast-growing poplar that temperature was 58°C, pH was 8.5, time was 120min and the dosage of the xylanase was 8IU/g. The pulp brightness was increased by 3.7%ISO when compared XDPQ and DPQ bleaching pulp under identical conditions. The pulp brightness was increased by 4.1%ISO when compared XDED and DED bleaching pulp under identical conditions. The untreated and pretreated Soda-AQ pulp of fast-growing poplar by the xylanase of two-dimensional and three dimensional figure of fiber surface under AFM were analyzed to explain the xylanase effect in the pulp bleaching theoretically.
