【摘要】 棉织物经壳聚糖处理后,再用栀子黄进行染色,测试并分析了染料用量、p H值、染色温度、染色时间对壳聚糖改性棉织物染色性能的影响,并设计正交实验来确定最佳染色工艺;且对染色后壳聚糖改性棉织物进行性能测试。结果表明,壳聚糖改性后棉织物的栀子黄染色性能较好;壳聚糖改性棉织物的最佳染色工艺为:栀子黄用量为9%、染色温度30℃、染色时间50 min、p H值为5;染色后壳聚糖改性棉织物防紫外线性能增强,耐摩擦色牢度及耐洗色牢度较好。更多还原

【Abstract】 The cotton fabric modified by chitosan was dyed by gardenia yellow,and the effects of dosage of dyes,p H value,dyeing temperature and dyeing time on the dyeing properties of cotton fabric modified by chitosan were tested and analyzed,and the optimal dyeing process was verified by orthogonal experiment.The properties of cotton fabric modified by chitosan after dyeing were tested.The results show that the dyeing property of cotton fabric modified by chitosan is better;the optimal dyeing process of cotton fabric modified by chitosan is that the dosage of gardenia yellow is 9%,dyeing temperature is 30 ℃,dyeing time is 50 minutes,and p H value is 5;UV-resistance property of cotton fabric modified by chitosan after dyeing is stronger,and fastness to rubbing and washing are good.更多还原
