摘　　要：采用鲜桑叶稀碱提取液直接同浴媒染丝织物,在实验条件下所染试样主要呈黄绿色,耐摩擦牢度和耐皂洗牢度较好,耐光牢度较差。文章探讨了不同的染色pH值、媒染剂对丝织物试样的色光和色牢度的影响。受媒染剂影响最大的是颜色值b*和a*。pH值变化影响最大的是a*值,其次是明度值L,然后是b*值。Mordant dyeing of silk fabric with thin alkali extracting solution from mulberry leaf was carried out with the mordantadded directly during the dyeing process. The dyeing samples are mainly yellow-green, which have high rubbing and washingfastness and low light fastness. The effects of different pH values and mordant on the color shade and color fastness werediscussed. It shows that the color values of b*and a* are the most affected by the mordant. The most affected color value by pHis a* value,the lightnes...
