摘　　要：用漂白亚硫酸盐竹浆制备纳米微纤化纤维素(MFC),将MFC与漂白硫酸盐蔗渣浆、漂白针叶木浆以及漂白阔叶木浆混合抄片,探讨了浆内添加MFC对纸张物理强度性能的影响;同时在相同条件下,对MFC和阳离子淀粉的涂布效果进行比较。结果表明,在低涂布量时,MFC涂布的纸张表面强度要高于阳离子淀粉涂布的纸张。In this paper, microfibrillated cellulose（MFC） was made from bleached bamboo sulfite pulp; then MFC was added in the mix pulp of bleached bagasse kraft pulp, bleached soft wood pulp and bleached hardwood pulp（CTMP） to make papers. The effects of MFC on paper strength were studied, and were compared with the effect of cationic starch. On the other hand, the MFC and cationic starch were coated on the paper respectively in order to make a comparison. The results gave clear indication that at low coating weight the paper coated with MFC has a higher picking velocity than that coated with cationic starch, and the paper coated with MFC has improved the physical strength.
