摘要
采用低分子质量壳聚糖对棉织物进行改性处理,用活性黑染料对其进行染色,讨论了壳聚糖改性对棉织物染色性能的影响,测定了其染色动力学参数。实验发现,通过壳聚糖改性后的棉织物,其平衡上染百分率可提高7.89%,染色扩散系数均得到提高(平均可至少提高了8.2%),扩散活化能下降了48.9%,表明壳聚糖改性可提高活性染料的染色性能。色度学参数值及K/S值结果表明,壳聚糖改性棉织物在活性黑染料中的增深效果明显,但对色光影响较小。
Cotton fabric was modified with low-molecular-weight chitosan, and then subjected to reactive dye in the paper. The influences of ehitosan modification on dyeing behaviors of cotton fabric were investigated and the parameters of dyeing kinetics were tested. Results show that equilibrium exhaustion and diffusion coefficients increased by 7. 89% and at least 8.2% respectively, diffusion activation energy greatly decreased by 48. 9%, which indicated that chitosan modification was beneficial to dyeing behaviors. The color coordinates show that chitosan modification had little effect on hue.
