Abstract

The invention relates to a method for degumming flax, and belongs to the field of flax degumming. The invention solves the problems of long degumming time and poor degumming effect of existing flax degumming. According to the invention, firstly, water in the flax is lost through drying; a part of micropores are formed inside the flax, soaking liquid is added to treat the flax; the soaking liquid takes polyvinyl alcohol as a raw material, is degraded through hydrogen peroxide in an alkaline solution, and then is combined to an additive, the flax can be effectively softened, and meanwhile, the flax can compete with gum substances to damage the degree of combination of the gum substances and the flax; and secondly, a trace additive is added in the invention, metal ions in the trace additivescan be effectively supported on the surface and pores of the flax, and then are mixed with a nutrient solution, and natural fermentation treatment is carried out to complete degumming of the flax.

Description

technical field [0001] The invention relates to a method for degumming flax and belongs to the field of degumming flax. Background technique [0002] Flax is an annual herbaceous plant, which originated in the Near East and the Mediterranean coast, and is widely planted in Eurasia. Flax fiber, known as the "Queen of Fibers", is the earliest natural fiber used by humans. As early as 10,000 years ago, the ancient Egyptians had already begun to grow flax. Flax fiber has many advantages such as moisture absorption, breathability, antibacterial health care, crisp and generous, ecological and environmental protection, warm in winter and cool in summer, etc. With the improvement of people's living standards, the requirements for fabric comfort and quality are getting higher and higher, and flax fiber products will be There is a very broad market. [0003] At present, flax spinning generally adopts wet spinning, but because flax roving contains more colloidal components, the degre...
