结果表明:精练酶去除木质素的效果比漆酶好,而精练酶+漆酶二步法处理的效果均较精练酶或漆酶单独处理为好,二步法处理后竹原纤维的细度变化率为51.33%,木质素含量从原来的18.98%降为5.49%。

• The results show that in terms of lignin removal,scouring enzyme is better than laccase,whereas the two step method is the best. After two step treatment,the change rate of fineness of natural bamboo fibers has achieved 51.33%25 and the content of lignin is decreased from 18.98%25 to 5.49%25.
