摘要: 针对桑椹染料在丝织物表面色深度低、色牢度差以及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、染色织物表面色深度(K/S、ΔE*)及染色牢度来探讨桑椹天然染料的颜色稳定性及其在丝绸织物的媒染效果。研究结果显示:桑椹天然染料在pH值4以下,温度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染色深度和牢度。

Abstract: Proper dyeing parameters and mordant dyeing process are required to improve the superficial color depth on silk fabrics and color fastness of the natural dye mulberry sorosis, and maximize its color performance, A study is therefore performed on this paper to discuss the stability of the natural dye mulberry sorosis and its mordant dyeing effect on silk fabrics through the testing on the absorption spectra of mulberry sorosis dye solutions, the superficial depth(K/S、ΔE*) and the dyeing fastness of the dyed silk fabrics. The experiments show that natural dye mulberry sorosis has satisfactory color feature under pH 4 and 80℃. The mordant dyeing, especially the post-mordanting dyeing can greatly improve the performance on both the dyeing depth and the color fastness of silk fabrics dyed of the natural dye mulberry sorosis.
