竹原纤维酶处理的纤细化效果

 为了探讨竹原纤维酶处理纤细化的有效方法,应用漆酶、精练酶及精练酶+漆酶二步法经正交设计对已制得的竹原纤维进行纤细化处理试验,测定酶处理后竹原纤维的细度变化率、木质素含量及强度。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%。

Probe into the impact of enzymatic treatment on the fineness of natural bamboo fibers

To probe into the effective methods to make the natural bamboo fiber finer with enzymatic treatment,the manufactured natural bamboo fibers were treated with laccase,scouring enzyme,and scouring enzyme laccase(a two step method) respectively according to the design by means of orthogonal experiment.The change rate of fineness,tensile strength and the content of lignin of the treated fibers were tested and compared.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% and the content of lignin is decreased from 18.98% to 5.49%.
