摘　　要：采用漆酶催化茶多酚聚合生成有色聚合物,通过吸附或接枝处理到羊毛纱线上,同时实现羊毛纱线的强力提升和“原位”染色。结果表明:染色毛纱呈棕黄色;通过对染色毛纱力学性质的分析,得出茶多酚的最适纯度为98%,最优浓度为0.05 mol/L,此时纱线断裂强力最高提升25.1%。Tea polyphenol is catalyzed by laccase to form colored oligomers or polymers,which can be ab⁃sorbed or grafted onto wool yarns to realize the powerful enhancement and"in-situ"dyeing of the wool yarn.The results show that the dyed wool yarn is brown.Through the analysis of the mechanical properties of the dyed wool yarn,it is concluded that the use of 0.05 mol/L tea polyphenol with a purity of 98%can increase the yarn breaking strength by 25.1%.
