摘　　要：采用壳聚糖对棉麻纤维进行阳离子改性实验,使棉麻纤维带上正电荷。改善了棉麻纤维上染率差等问题,有效提高了棉麻织物对染料的吸附性能。文章从研究茜草染料上染壳聚糖改性棉麻纤维的角度探讨了茜草染料染色的浓度、时间、温度、媒染剂的用量对染色效果的影响。The cation modification of cotton and linen fiber with chitosan was carried out to make the cotton and linen fiber positively charged.The problems of poor dye uptake of cotton and linen fibers are improved,and the adsorption performance of cotton and linen fabrics to dyes is effectively improved.In this paper,the effects of concentration,time,temperature and the amount of mordant on the dyeing effect of alizarin dye on chitosan modified cotton fiber were discussed.
