摘要
采用生物法对竹原纤维进行精细化处理,探讨了纤维素酶处理工艺对竹原纤维线密度和残胶率的影响。结果表明,随着纤维素酶浓度、处理时间和温度的增加,竹原纤维线密度逐渐减小后趋于平缓,残胶率均呈先降低后增大的趋势;最佳处理工艺条件为:纤维素酶浓度1.5%,温度55℃,时间180 min,处理后竹原纤维线密度为6.58 tex,比处理前降低了35.5%;残胶率为18.43%,比处理前降低了15.14%。
The effects of enzymatic treatment on the refining of natural bamboo fibers were studied. The experimental results showed that the fiber linear density gradually decreased to a constant and the residual gum firstly decreased and then increased with the increasing of cellulase concentration, treatment time and temperature. And the optimum conditions could be expressed by eellulase concentration of 1.5%, treatment time of 180min and temperature of 55℃. The fibers after treated had the linear density of 6.58 tex, decreased by 35. 5% than those untreated, and the content of residual gum of 18.43%, decreased by 15. 14%.
