摘　　要：针对麻纤维采用化学脱胶会对纤维造成损伤的问题,提出了大麻纤维生物酶脱胶的新方法。并且用正交试验方法确定了生物酶脱胶的最佳工艺,即作用时间2h,果胶酶浓度5g/L,pH值4.5,温度50℃;后处理氢氧化钠浓度0.6%。生物酶对大麻进行脱胶处理,其作用条件温和,对纤维损伤小,生产中容易掌握脱胶的程度,有利于提高出麻率,且耗水少、污染轻。Degumming of hemp with chemicals results in fibre damages. For this reason,a new degumming method of hemp fibres with enzyme is proposed,whose optimal process conditions are determined through orthogonal test as follows:reacting time 2h,concentration of pectinase 5g/L,pH=.5,treating temperature 50℃; concentration of sodium hydroxide for aftertreatment 0.6%. enzymatic degumming of hemp fibres has such advantages as mild process conditions,less fibre damages,easy control of the degree of degumming,beneficial to raising the yield,less water consumtion and slight pollution.
