菠萝叶纤维酶法脱胶技术

为充分利用热带农业生物资源,弥补我国天然纺织原料的短缺,对菠萝叶纤维进行了酶法脱胶技术的理论探讨和试验研究。从自然界筛选高产果胶酶菌株,发酵生产出高活性果胶酶。研究结果表明:果胶酶用量8%,pH值7.0,温度52℃,处理4 h左右菠萝叶纤维能达到良好的脱胶效果。脱胶后菠萝叶纤维再经木聚糖酶处理45 min,再用30%的H2O2处理15 min能满足纺织工艺要求。

Study on enzymatic degumming of pineapple leaf fiber

In order to make full use of tropical agricultural biotic resources and make up raw material shortage for textile industry in China,enzymatic degumming of pineapple leaf fibre was explored in both theoretical and practical aspects. Purified pectase with high enzymatic activity from a strain screened by us was used.It was shown that the optimal result of degumming could be achieved when reaction conditions were pectinase dosage 8%,pH value 7.0,(52 ℃) and treated for 4 hours.A post_treatment after degumming with xylanase for 45 min and following treatment with H_2O_2 for 15 min would yield fiber qualified for textile utilization.
