摘　　要：采用氯乙酸对棉纤维进行阴离子改性,考察了氯乙酸质量浓度、乙醇体积分数、改性温度和时间对黄连素染色性能的影响。结果表明,氯乙酸改性棉纤维的优化工艺为:烧碱150 g/L,乙醇40%,30℃碱处理2 h,再用氯乙酸150 g/L,乙醇40%,60℃改性2 h;改性棉织物在黄连素2%(omf),p H=5,60℃染色60 min的条件下,可以获得较深的颜色,但其色牢度有待改善。Anionic cotton fabric is prepared by chloroacetic acid modification. The effects of chloroacetic acid and ethanol concentrations, modification temperature and time on dyeing behaviors of berberine are analyzed. The results indicate that the modification process of cotton fabric is optimized as follows： pretreatment at 30℃ for 2 h with sodium hydrate 150 g/L and ethanol 40%, and then treating at 60 ℃ for 2 h with chloroacetic acid 150 g/L and ethanol 40%. The modified cotton fabric is dyed at 60 ℃ for 60 rnin with berberine 2%（omf） and pH value 5. The dyeings feature deep shade but a slightly low color fastness.
