摘要

Synergistic effect of xylanase and bleaching agent on bleaching properties of KP pulp was investigated. The combination of ClO_2 chlorination, alkali extraction and ClO_2 bleaching with xylanase was applied. Results showed that X/DED bleaching process could make full use of xylanase, xylan was degraded and the role of bleaching agent was accelerated which enhancing the chemical accessibility of xylanase. The coordination of the two parts improved bleaching effect significantly. But for DX/ED bleaching process, the brightness of bleached pulp treated with different xylanase treating time was very low or a little low, indicating the role of xylanase on pulp was very important for improving bleaching properties, and residual xylanase had little effect on improvement of alkaline extract. Effect of xylanase in ClO_2 stage had little effect on bleaching effect of pulp, and brightness are near each other. When xylanase and ClO_2 were added together, xylanase almost did not show its role in bleaching, and bleaching result was neat to that of DED process.
