摘　　要：为提高天然色素栀子蓝在棉织物上的染色深度和染料利用率,利用含季铵基团的阳离子改性剂对棉织物进行改性。通过试验确定最佳的改性工艺,并对改性后棉织物的表面Zeta电位及形貌进行表征。利用天然染料栀子蓝对改性棉织物进行染色,探讨最佳染色工艺。研究结果表明:棉织物的最佳改性工艺为阳离子改性剂质量浓度5 g/L,NaOH质量浓度3 g/L;最佳染色工艺为染色温度80℃,保温时间60 min。改性棉织物的栀子蓝染色K/S值可达4.8,染料的上染率为54%。In order to improve the dyeing depth and dye utilization of natural pigment gardenia blue on cotton fabric,cationic modifier containing quaternary ammonium group is used to modify cotton fabric.The optimum modification process is determined through experiments,and the Zeta potential and morphology of the modi⁃fied cotton fabric are characterized.The modified cotton fabric is dyed with natural dye gardenia blue,and the optimum dyeing process is studied.The results show that the best modification process of cotton fabric is 5 g/L of cationic modifier and 3 g/L NaOH.The optimum dyeing process is dyeing temperature 80℃,holding time 60 min.The K/S value of modified cotton fabric dyed with gardenia blue can reach 4.8,and the dye uptake is 54%.
