摘　　要：针对桑椹染料对丝织物染色亲和力低、色牢度差的问题,为最大程度表现桑椹染料颜色特点,选择合理的桑椹染料染色工艺参数、媒染工艺对丝织物进行染色。通过测试桑椹染液的可见吸收光谱、染色织物色度(K/S值)及染色牢度来探讨桑椹天然染料的颜色稳定性及其对丝织物的媒染效果。研究结果显示:桑椹染液在pH值为4以下、温度为80℃以下表现出良好的颜色特征;利用媒染工艺,尤其是后媒染色工艺可以较大程度提升桑椹染料在丝织物上的染色深度和牢度。Low affinity and poor color fastness are confronted when dyeing silk fabrics with mulberry dye.For fully displaying the color feature of mulberry dyes,proper dyeing parameters and mordant dyeing processes were selected to dye silk fabrics.The stability of natural dye mulberry sorosis and its mordant dyeing effects on silk fabrics were investigated by testing the visible absorption spectra of mulberry sorosis dye solutions,color depth（K/S value） and color fastness of the dyed silk fabrics.The results indicated that natural dye mulberry sorosis solution showed satisfactory color feature at pH of 4 and 80 ℃.Mordant dyeing,especially post-mordanting dyeing process,can greatly improve the performances on both color depth and color fastness of the silk fabrics dyed with natural dye mulberry sorosis.
