| 摘 要： | 为克服单一化学法脱胶对环境污染严重和单一的生物酶脱胶率低的缺点,研究了大麻纤维高温-酶联合脱胶技术,讨论了高温脱胶后3种不同酶处理的大麻纤维化学成分与断裂强度的变化,用SEM、FTIR对大麻纤维高温酶脱胶前后的表面形态结构、化学成分进行表征。实验结果表明:果胶酶可作为高温脱胶后大麻纤维的脱胶酶使用;高温-果胶酶脱胶后大麻纤维中的果胶和半纤维素、木质素含量分别下降了83.3%和79.2%。

| Abstract: | Chemical retting causes serious environmental pollution,and enzymatic retting has the drawback of poor yield.In order to overcome these disadvantages,hemp retting by the combined action of high temperature boiling and enzymes was researched.Hemp retting was performed by high temperature boiling,followed by enzymatic retting.And the effect of three kinds of enzymes on the composition and breaking strength of hemp was discussed.The morphology and composition of hemp after high temperature boiling-enzyme treatment were characterized by SEM and FTIR.The results show that pectase is suitable for hemp retting following high temperature boiling retting.Hemp retting by high temperature boiling,followed by pectase treatment can remove hemicellulose and lignin by 83.3% and 79.2%,respectively. |
