摘　　要：采用水煮法提取栾树叶染液,以明矾和皂矾为媒染剂,采用直接染、预媒染和后媒染3种方法对纯棉针织物进行染色,获得枯黄色、浅棕灰色和暗灰色3种色调。选择明矾预媒染和皂矾预媒染的方法进行单因子染色试验。试验结果表明,明矾预媒染和皂矾预媒染的优化提取料液比均为1∶10。明矾预媒染的优化染色工艺为:pH值7、时间30 min、温度70℃。皂矾预媒染的优化染色工艺为:pH值6、时间30 min、温度40℃。明矾预媒染和皂矾预媒染后织物的耐洗涤、耐摩擦和耐日晒色牢度均达到3~4级或以上,其中耐日晒色牢度尤为突出,分别为4~5级和5级。Extracting solution of koelreuteria paniculate leaves is obtained by boiling method.Using alum and melanterite as mordant,cotton knitted fabric is dyed by direct,pre-mordant and post-mordant dyeing process,and accordingly three colors of dry yellow,light brown gray and dark gray are obtained.Single factor dyeing experiments are carried out with dyeing methods of alum pre-mordant dyeing and melanterite pre-mordant dyeing.The results show that the optimum material-liquid ratio in alum pre-mordant and melanterite pre-mordant dyeing is 1∶10;The optimum dyeing process of alum pre-mordant dyeing is:dyeing at 70℃for 30 min with pH 7;The optimum dyeing process of melanterite pre-mordant dyeing is:dyeing at 40℃for 30 min with pH 6.The color fastness to washing,rubbing and sunlight of the fabric dyed with alum pre-mordant and melanterite pre-mordant can reach 3~4 levels or above,with particularly outstanding color fastness to sunlight,reaching 4~5 levels and 5 levels,respectively.
