摘　　要：以红苋菜为原料,通过正交试验优化了红苋菜色素的最佳提取工艺:提取剂为无水乙醇,70℃水浴浸提60 min后,超声波处理40 min,料液比1∶15,p H值7。氯化镁作为媒染剂对真丝织物进行后媒染染色的最佳工艺为:染色时间60 min,染液p H值6,浴比1∶30,染色温度60℃。With Amaranthus Paniculatus pigment as raw materials, orthogonal experiment is carried out. The optimized extraction technology of Amaranthus Paniculatus pigment is using anhydrous ethanol as extracting agent, extracting at 70 ℃water bath for 60 min and then ultrasonic treating for 40 min, sol- id-liquid ratio of 1 ： 15, pH value of 7. Magnesium chloride is used as mordant to after-mordant dyeing of silk fabric. Its optimum dyeing process is pH value of dye liquor 6, liquor ratio 1：30 and dyeing at 60 ℃ for 60 min.
