摘　　要：本文利用从蔗渣中提取的半纤维素为原料,在碱性条件下对半纤维素进行阳离子化改性。研究了蔗渣阳离子半纤维素作为造纸助剂对漂白蔗渣浆成纸性能的影响。实验结果表明,相对于原漂白蔗渣浆,在纸浆悬浮液中加入阳离子化半纤维素后,成纸的各种物理强度有所增加,当其用量为0.8%时,成纸的抗张指数、抗张强度、裂断长、耐破指数、耐折度相对于未加阳离子半纤维素的纸张分别提高了43.79%、36.95%、33.11%、17.35%、33.33%.;随着阳离子半纤维素加入量的增加,纸张的白度呈现下降的趋势。In the papers,we synthesized a kind of cationic hemicelluloses through cationic modification using sugarcane bagasse hemicelluloses as the raw material,reacting with cationic reagent in alkaline condition.As paper additive,the effect of cationic hemicellulose on bleached bagasse pulp was researched.Then pulp handsheet properties were studied.The results indicated that adding the cationic hemicellulose could increase paper mechanical strengths,and its effect was better than original bleached bagasse pulp.At the dosage of 0.8% on oven dried pulp,paper tensile index,tensile strength,breaking length,burst index and folding endurance can be increased by 43.79%,36.95%,33.11%,17.35%,33.33% respectively,which are much better than those of the paper without the cationic hemicellulose.With the increased dosage of cationic hemicellulose,the trend of paper brightness declined.
