夏布酶法后整理条件的优化

 为了确定夏布酶法后整理的工艺流程和技术参数,在利用高效木聚糖酶和纤维素酶等复合酶进行夏布后整理的基础上,研究酶的用量、浴比、温度、起始pH值和处理时间等因子对夏布酶法后整理的影响。结果表明夏布酶法后整理的适宜条件为:木聚糖酶用量(对夏布)0.5%,纤维素酶用量(对夏布)0.5%~2%,浴比1∶15,温度50℃,起始pH值4.5~5.0,时间1 h;夏布酶法后整理中,纤维素酶浓度对整理效果的影响最大,起始pH值次之,浴比的影响最小。

Optimization of enzymatic finishing conditions of hand-made ramie cloth

For optimizing the process conditions of enzymatic finishing of the hand-made ramie cloth,high efficiency mixture of xylanase and cellulase was employed in the enzyme finishing of the cloth.The effects of enzyme dosage,bath ratio,temperature,pH value and duration of treatment on the finishing result were investigated.It demonstrated that the optimized process conditions of enzymatic finishing of the hand-made ramie cloth are as follows: 0.5% xylanase,0.5%～2% cellulase,bath ratio,1∶15,pH value at the range of 4.5～5.0,and treating at(50 ℃) for 1 hour.Among the factors influencing the finishing,cellulase concentration is in the first place,and followed by original pH value,the last is bath ratio.
