摘　　要：艾蒿天然色素在水中以染料阴离子的形式存在,与棉纤维亲和力低。为提高染色深度及牢度,采用阳离子改性剂LD-8202对棉纤维进行改性,文章探讨了改性剂用量、改性时间、Na2CO3用量及改性温度对棉织物染色性能的影响,通过单因素实验和正交实验优化了改性工艺。通过UPF值测试得知,艾蒿色素可以赋予改性棉织物良好的抗紫外性。Mugwort natural pigment is anionic dyes in water, and has low affinity with cotton fiber. In order to improve the dyeing depth and fastness, cotton fiber was modified with cationic modifier LD-8202. The dosage of modifier, modifying time, Na2CO3 dosage and temperature on dyeing modification effect of cotton fabrics were explered. Through the single factor experiment and orthogonal experiment,the process was oplimized. Through the test the value of UPF, mugwort pigment can give the modified cotton fabric excellent resistance to UV.
