摘　　要：利用壳聚糖对漂白硫酸盐浆进行预处理,分别采用Cartasol Red 2FGN liquid直接染料及Cartasol BlueK-2R liquid阳离子直接染料对纸浆进行染色,研究壳聚糖黏度、用量及pH值对染色效果的影响,同时就壳聚糖与硫酸铝的协同效应进行研究。结果表明,增大壳聚糖黏度和用量可提高直接染料染色色度;黏度对阳离子直接染料染色影响不大,但随着其用量的增加,染色色度先增后降;壳聚糖溶液的pH对两种染料的染色效果影响不大。另外,壳聚糖与硫酸铝在直接染料染色时协同效应明显,但在阳离子直接染料染色时较差。The bleached kraft pulp was first treated by chitosan, then dyed by Cartasol Red 2FGN liquid and Cartasol Blue K-2R liquid repectively with aim to study the infuence of chitosan on dye process. It was found that the color chromaticity of paper dyed by direct dye increased with chitosan viscosity and dosage increasing respectively. Chitosan viscosity had little effect on chromaticity of paper dyed by cationic direct dye, while the dosage of chitosan was more sensitive to color chromaticity. It was also showed that color chromaticity didn＇t inrease significantly by raising the acidity of chitosan solution in both two dyes. Furthermore, the synergistic effect between Al2（SO3）4 and chitosan was good while using direct dye, but it was poor while using the cationtic direct dye.
