不同分子量壳聚糖及其季铵盐改性亚麻织物染色性能的研究

摘要

Flax fabric was modified by different molecular weight chitosan and its quaternary ammonium salt and dyed with low-temperature, medium-temperature and high-temperature reactive dyes. The results showed that the whiteness of the modified fabric decreased. Comparing with the untreated flax fabric, the dyeing properties of the modified flax fabric improved, especially the fabric modified by chitosan quaternary ammonium salt. The dry and wet rubbing fastness of the modified fabric increased one level.%使用不同分子量的壳聚糖及其季铵盐对亚麻织物进行改性，并用低温、中温、高温活性染料进行染色，与未改性加盐染色对比，结果发现使用低分子量壳聚糖及其季铵盐改性后的亚麻织物白度均有所下降，利用三种染料进行染色，染色性能均有不同程度的提高，且季铵盐改性后的提升效果更为显著，经过改性后的织物染色后干湿摩擦牢度大多提升1级。
