摘　　要：对苏木天然染料染色柞蚕丝织物的色光稳定性进行了研究。采用不同pH值的水溶液、氧漂液、高温加热和光照来处理染色后的柞蚕丝织物,通过测试织物的色度指标值(L*、a*、b*、c*值及K/S值)和染色牢度来探讨染色织物的色光稳定性。研究结果表明:pH值对苏木染色蚕丝织物的色光影响最大;过氧化氢漂白液会使织物褪色,铁媒染色织物虽然褪色较轻,但有明显的色调变化;光照使被染丝织物的色调发生改变,饱和度与鲜艳度降低;温度对色光稳定性的影响最小。媒染剂及其种类会影响被染丝织物的颜色和颜色稳定性。This paper studies the chromatic light stability of tussah silk fabrics dyed with natural dye sappanwood,treats tussah silk fabrics after dyeing with aqueous solutions of different pH values,oxygen bleaching liquor,high-temperature heating and illumination and discusses the chromatic light stability of dyed fabrics by testing index values of chroma（L＊,a＊,b＊,c＊ and K/S） and color fastness of fabrics.The research result shows that pH value has the greatest influence on chromatic light of tussah silk fabrics dyed with sappanwood;hydrogen peroxide bleaching solution fades fabrics;iron mordant dyeing fabrics have an obvious tonal variation though the fading is light;illumination makes the tone of dyed silk fabrics change and reduces the saturation and vibrance;and temperature has the minimum influence on chromatic light stability.Mordant and its type influence the color and color stability of dyed silk fabrics.
