摘要
采用漆酶与酸性纤维素酶协同作用来降低牛仔布生物整理中的返沾色。结果表明:单独添加酸性纤维素酶虽然除毛效果好、剥色明显,但靛蓝染料对牛仔布的返沾色较重。而添加漆酶与酸性纤维素协同整理时,可以显著减少返沾色;当漆酶用量为5.0 g/kg牛仔布时,牛仔布的返沾程度减少83%,协同水洗时间以60 min为宜。牛仔布水洗整理的工厂放大试验显示:漆酶与酸性纤维素酶协同作用,一方面可使牛仔布的返沾色显著减弱,获得独特的“雪花”效果;另一方面还可使工厂废水中的靛蓝含量减少80%,有利于降低环境污染。
Reducing backstaining of blue jeans by the synergism of laccase and acid cellulase during the biofinishing was experimented. The finding indicated that only adding acid cellulase has achieved a good effect in the dehairing and decolorization of blue jeans during the biofinishing, but results in heavy indigobackstaining. In the presence of laccase, the degree of backstaining can be greatly decreased. The suitable synergistic washing time was 60 min and when the amount of laccase was 5.0 g/kg （o.w.f）, the backstaining degree was reduced by 83 %. The plant scale experiments demonstrated that the synergism of laccase and acid cellulase not only reduced the backstaining and imparted the blue jeans the unique ＂snowflake＂ effect, but also reduced the amount of indigo blue in wastewater by 80 %, which was of great benefit to alleviating environment pollution.
