摘　　要：概述了木聚糖酶辅助纸浆漂白的意义和现状,分析硫酸盐木浆ECF漂白工艺条件,提出在ECF漂白中应用酸性木聚糖酶的方案。介绍国内外科研工作者对纸浆辅助漂白木聚糖酶研究的最新成果。指出用于纸浆漂白的木聚糖酶应具备以下酶学性质：在70~90℃高温环境下保持长效活力,不含纤维素酶或者纤维素酶活较低,具有一定的碱稳定性。低分子量的木聚糖酶有利于提高漂白效率。The xylanase-assisted pulp bleaching technology was summarized of kraft wood pulp ECF in this paper. The conditions bleaching processes was analyzed, the application program for applying xylanase under acidic condition in ECF bleaching was put lbrward. A series of new research results domestic and abroad were introduced, which show that xylanase to be applied in pulp bleaching must possess such properties as keeping the long term bioactivity at 70~90℃ reaction temperature, free from cellulase or low cellulase bioactivity and stability in alkaline condition. Furthermore, xylanase with lower moleculer-weight proved to be favorable to improve bleaching efficiency.
