Abstract: In this paper, the controlled degumming of flax rove was carried out by using compound enzyme. The effects of the degumming process conditions on the degumming effect of the flax rove and the properties of the spun yarn were studied. Results indicated that this crude enzyme could effectively remove hemicelluloses and lignins as well as partial pectins in flax roves. The prepared rove has excellent spinnability, and the flax sliver is even and has high strength and less hai riness on the surface of the yarn.

Key words: flax; crude enzyme; degumming; spinnability
