摘　　要：采用儿茶素对蚕丝织物和羊毛织物进行同浴染色,探讨媒染剂种类、媒染剂用量、染料用量、染色温度和染色时间对两种织物染色同色性的影响。得到蚕丝织物和羊毛织物同色性媒染的最佳工艺为:明矾5 g/L,儿茶素6%(omf),pH=5.5,浴比1∶50,80℃同浴媒染30 min。采用该工艺染色的织物色牢度优良,蚕丝织物的抗紫外性能大大提高。One bath dyeing of silk and wool fabrics using catechin as dyes is carried out.The influences of mor⁃dant types,mordant concentrations,dye concentrations,dyeing temperature and dyeing time on the homochro⁃matic dyeing results of two fabrics are discussed.The optimal process for homochromatic mordant dyeing of silk and wool fabrics is as follows:alum 5 g/L,catechin 6%(omf),pH=5.5,bath ratio 1∶50,and mordant dyeing at 80℃for 30 min in one bath.The dyeings have excellent color fastness,and the UV protection of silk fabric is greatly improved.
