摘　　要：对中小径竹硫酸盐浆进行了ECF漂白的研究。探讨了氧脱木素、半纤维素酶辅助漂白、ClO2漂白、碱抽提的影响因素,进行了工艺条件的优化并比较了几种漂白流程。研究结果表明,采用OXD1EOPD2漂白流程,漂后白度达到87.4%ISO。漂白效果优于OD/CEOPD2漂白流程。ECF bleaching of bamboo kraft pulp was carried out in this study. Some factors affecting enzymes treatment, C1O2 bleaching, Eop etc. were studied. The optimized conditions for each were dediced. Several bleaching sequences were compared. The conclusion was that the bleaching result of O-X-D1-Eop-D2 is better than O-D/C-Eop-D2. The brightness of the bleached bamboo pulp can achieve 87.4%ISO.
