摘　　要：经过酶改性纸浆纤维具有很高的利用价值,如改善纸浆的滤水性、降低打浆能耗、改善成纸的某些强度。棉纤维性质强韧,纤维较长,是极好的造纸原料,但由于纤维结晶度高,纤维紧密,致使其很难打浆。本实验用纤维素酶对棉浆进行改性,再将经酶改性后的棉浆与针叶木浆进行配抄,探讨酶改性后的棉浆与针叶木浆的配抄性能。Modified pulp by ceUulase have great advantages, such as improving drainability of pulp, raising the strength properties of paper sheet, as well as reducing the beating energy consumption. Cotton fiber has a tough property and a long length, accordingly is an excellent raw material for papermaking. However, cotton pulp＇s high crystallinity and tight fiber configuration result in hard beating. By modifying cotton pulp with cellulase, the study discussed the properties of modified cotton pulp blending with softwood pulp.
