摘　　要：通过漆酶催化茶多酚和五倍子生成黄棕色氧化产物,并用于羊毛纱线染色。探究染色条件对两种底物上染羊毛纱线染色性能及染后羊毛力学性能的影响。结果表明,酶促茶多酚上染羊毛纱线的最佳工艺为漆酶40 U/mL,染液pH为5.0,染色时间4 h,染色温度50℃;酶促五倍子上染羊毛纱线的最佳工艺为漆酶40 U/mL,染液pH 5.5,染色时间5 h,染色温度40℃。茶多酚染色羊毛纱线可获得更加优异的力学性能,五倍子染色羊毛纱线的K/S值更高;同时,染色羊毛纱线具有优良的耐碱性、防紫外线性能以及抗氧化性。Laccase can catalyze tea polyphenols and gallnut to produce yellow and brown oxidation products,which can be used to dye wool yarn.The effects of dyeing conditions on dyeing properties of wool yarn with two substrates and mechanical properties of dyed wool yarns are investigated.The results show that the op⁃timal process for laccase catalyzed tea polyphenols dyeing on wool yarn is laccase concentration 40 U/mL,pH 5.0,dyeing time 4 h,dyeing temperature 50℃.The optimal process for laccase catalyzed gallnut dyeing on wool yarn is laccase concentration 40 U/mL,pH 5.5,dyeing time 5 h,dyeing temperature 40℃.Wool yarn dyed with laccase catalyzed tea polyphenols has better mechanical properties,while wool yarn dyed with laccase cat⁃alyzed gallnut has a deeper color depth.At the same time,this dyeing method also endowes the wool yarn with excellent alkali resistance,UV resistance,and antioxidant properties.
