Degumming method and device for bast fibers

The invention relates to a degumming method and a degumming device for bast fibers. The degumming method comprises the following steps of: mechanically degumming, biologically degumming and/or degumming through high-temperature cooking, sintering at high temperature, and distributing fiber and washing with water; and the degumming device comprises a mechanical degumming device, an inoculated fermentation device, a high-temperature liquid circulating device, a fiber distributing and water washing device and a yarn hanging device. The method and the device have the advantages of reasonable procedures, obvious degumming effect, good homogenization and consistence, high degumming operating efficiency, strong controllability, and neat bulk fiber processed. The invention can effectively reduce environmental pollution, so the invention can be widely applied to the degumming process of various bast fibers.
