有机溶剂在欧洲大麻脱胶中的应用
|
摘要
随着绿色环保理念越来越深入人心,针对常规的无机溶剂脱胶对环境带来的诸多负面效应以及能耗大等一系列问题,提出利用乙二醇和1,4-丁二醇这2种有机溶剂对大麻进行脱胶,分别研究了温度、时间这2个主要工艺参数对欧洲大麻纤维胶质去除率的影响,并对2种溶剂的脱胶处理效果进行了对比。结果发现:用1,4-丁二醇处理欧洲大麻纤维,在油浴温度为200℃,处理时间为2. 5 h时脱胶效果较为理想,胶质去除率可达67. 73%,残胶率为10. 73%,能够满足大麻纤维的纺纱要求。
Nowadays,the concept of environmental protection is getting more and more popular. In view of the problems caused by conventional inorganic solvent degumming on environment and energy consumption,it was proposed to degum hemp fibers by using two kinds of organic solvents,ethylene glycol and 1,4-butanediol. The effects of temperature and time on the removal rate of European hemp fibers colloid were studied,and the degumming effects of the two solvents were compared. The results showed that when the European hemp fibers were treated with 1,4-butanediol,the ideal degumming effect was achieved under the oil bath temperature of 200 ℃ and the treatment time of 2.5 h. In this case,the colloidal removal rate of European hemp fibers was 67. 73%,and the residual glue rate was 10. 73%,which can meet the spinning requirements of hemp fibers.
