摘　　要：探讨了漂白麦草浆在反复回用过程中纸页物理性能的变化规律,并重点探讨了酶处理对改善漂白麦草浆二次纤维性能的可能性。结果表明:漂白麦草浆回用后,打浆度、抗张强度、耐破指数、耐折度、还原糖含量均下降;第一次回用后下降的程度最大;撕裂指数随回用次数的增加而上升,开始上升很快,以后就趋于平缓。半纤维素酶和木聚糖酶能够改善漂白麦草浆二次纤维的性能,两种生物酶对漂白麦草浆前几次回用的改善效果并不是很明显,但对回用多次后的漂白麦草浆能获得良好的效果。The change rule of physical and paper properties of the bleached wheat straw pulp during recycling is studied in this paper. Biological enzymes treatment is used to improve the recycled fiber properties. The results indicate that the pulp freeness, tensile strength, folding strength , burst index and hemi-cellulose content decrease with recycling. Tear index is increased initially, reduced when the bleached wheat straw pulp is recycled. Hemicellulose and Xylanase could improve the recycled fiber properties, but the effect is not obvious in the initial several times.
