摘　　要：研究了碎浆过程中OCC纤维的物理化学性能及其成纸性能的变化。研究结果表明:随着碎解时间的增加,OCC纤维逐渐疏解成单根纤维,同时纤维也产生了一定程度的切断现象,纤维平均长度下降了4.35%;纤维表面出现不同程度的细纤维化;细小纤维重均含量增加了8.5%;保水值呈现增加趋势,最大提高了14.3%;碎浆处理对纤维结晶现象的影响不大。纸页抗张指数和撕裂指数分别提高了12%和22.2%。在碎浆过程中没有新的化学基团的产生,随着碎浆时间的增加纤维素分子间的氢键作用有所减弱。Physical and chemical properties and variation in paper properties of old corrugated container （OCC） fiber during defibration process were investigated. The results show that with the increase of defibrating time, the fiber bundles decrease gradually, and became single fiber finally; meanwhile some fibers are cut off on some extent. The average length decreases by 4.35%; but the fines content in- creases by 8.5%, and the water retention value （WRV） of the fibers increases gradually, with the maximum up to 14.3%; the tear and tensile index of the fibers increase by 12% and 22.2% respectively. Defibrating process has little impact on the crystalline degree in the fibres, and no new chemical group appears, but the strength of the hydrogen bonds in cellulose molecules decreases.
