摘要
应用漆酶DeniliteIIS进行了染液脱色与棉染物酶洗试验,考察了不同助剂对漆酶处理效果的影响。结果表明:阴离子表面活性剂十二烷基硫酸钠、螯合剂EDTA等对漆酶酶活有一定的抑制作用;非离子表面活性剂平平加O和吐温-80能增加漆酶反应活性,使脱色率(数量、比例)增加。漆酶与吐温-80复配的皂洗酶对棉染物有较好的酶洗效果,处理后织物湿摩擦牢度有所增加。
The laccase of Denilite IIS was used for dye decolorization and bio-soaping in cotton fabric. Effects of different chemical additives on the treatment result of laccase were investigated. The results indicated that anionic surfactant of sodium dodecyl sulfate and the chelating agent of EDTA inhibited the enzyme activity of laccase, while nonionic surfactants of peregal O and Tween-80 increased the activity of laccase, and raise the decolorization efficiency. The bio-soaping agent formulated by laccase and Tween-80 showed high soaping efficacy for the dyed cotton fabric and the wet rubbing fastness of the treated fabric was improved as well.
