摘要 主要探讨鹿蹄草提取液对真丝绸的直接染色工艺及真丝绸媒染工艺。通过单因素试验及正交试验分析,得出真丝绸直接染色pH值为约3.50,鹿蹄草染液质量浓度为10g/L,染色温度为90℃,浴比为50∶1,染色时间为50min。采用不同种类媒染剂和媒染方法,测试分析得到媒染剂硫酸亚铁比硫酸铜的媒染效果好,尤其是耐摩擦色牢度以及沾色色牢度。后媒染的媒染效果比预媒染和同浴媒染的效果好。 The direct dyeing process of silk fabric dyed with natural dye wintergreen extract and the mordant process of silk fabric were discussed.By the analysis of single factors and orthogonal experiments,the best dyeing process conditions of silk fabric were as follows:pH value was 3.5 around,the quality concentration of wintergreen was 10 g/L,dyeing temperature was 90℃,liquor ratio was 50∶1,and dyeing time was 50 min.Using different kinds of mordants and mordant dyeing methods,it was found that the mordant ferrous sulfate had better dyeing effect than copper sulfate,especially rubbing fastness and staining fastness.And the effect of after-mordant dyeing was better than that of the pre-mordant dyeing and one-bath mordant dyeing.
