摘　　要：探索稀土、皂土在姜黄植物染料对真丝织物染色中的作用,为植物染料新型媒染剂的开发应用提供参考,选用了硫酸铝钾、硫酸亚铁、皂土、稀土4种媒染剂,以天然姜黄色素为染料对真丝织物进行染色,测试并分析不同方法染色试样的K/S值、摩擦色牢度和耐洗色牢度等。结果表明:皂土和稀土作媒染剂的最佳工艺是浴比为1︰50,始染温度40℃,媒染温度90℃,媒染时间45 min,质量浓度均为0.6 g/L(3%o.w.f)。皂土和稀土作媒染剂可以提高上染率,提高染色织物的表面深度,改善染色牢度。不同媒染剂在提高上染率、改善色牢度的同时,还可使染料的色相发生多种变化,丰富天然染料的色相。This paper explores the effect of rare earth and bentonite in dyeing of real silk fabrics by turmeric vegetable dye; provides reference for the development and application of new mordant of vegetable dye; uses four mordants - aluminium potassium sulfate, ferrous sulfate, bentonite and rare earth; dyes real silk fabrics with natural curcumine as dye and tests and analyzes K/S value, rubbing fastness and color fastness to washing of samples dyed with different method. The result shows that the optimal process of bentonite and rare earth as mordants is bath ratio 1：50, initial dyeing temperature 40 ℃ , mordanting temperature 90 ℃ , mordanting time 45 min and mass concentration 0.6 g/L （3% o. w. f）. Bentonite and rare earth used as mordants can improve the dye-uptake, surface depth of dyeing fabrics and color fastness. Different mordants can make the hue of dyeing change and enrich the hue of natural dyeing while improving dye-uptake and color fastness.
