The invention belongs to the technical field of spinning processing, and in particular relates to an integral sisal hemp degumming process which comprises steps of pretreatment, high pressure alkali boiling, impurity removal, corona discharge treatment, fungi degradation, water washing, press drying, oil feeding, shaping and drying. With integral degumming of high pressure alkali boiling, corona discharge treatment and fungi degradation, the integral sisal hemp degumming process has effects prior to those of conventional single chemical degumming methods or mechanical degumming methods, is relatively low in content of residual gum and lignin and meets process requirements of deep processing of sisal hemp. In addition, except acetic acid and a small amount of sodium hydroxide, no other chemical reagents are used, so that a relatively small amount of pollution sewage can be discharged, and the process is a relatively green and environmental-friendly process method.
