A kind of ramie biochemical degumming method

Abstract

The invention discloses a biochemical degumming method for ramie. The biochemical degumming method is characterized in that after the steps of stowing and fermenting, soaking and fermenting, primary boiling, secondary boiling, refining, oil feeding and fermenting, and the like are performed, the biochemical degumming new fermenting technique is adopted, so that the usage amount of alkaline and chemical auxiliary materials and the amount of residues in wastewater are reduced, and the treatment cost of wastewater is reduced; the amount of remained gum in the refined dry ramie is little, and the quality is stable. The biochemical degumming method has the advantages that the technology is simple, the operation is easy, and the industrial production is favorable.

Description

technical field

[0001] The invention relates to the technical field of ramie treatment, in particular to a biochemical degumming method for ramie. Background technique

[0002] Ramie fiber comes from ramie bast, accounting for about 65%, and the remaining non-cellulose components account for about 35%, including hemicellulose, pectin, lignin, etc., collectively referred to as colloids. In the current degumming process, chemical degumming is commonly used. Among them, alkali boiling degumming is widely used because of its simple process and easy access to raw materials. However, this type of degumming technology has defects such as: (1) Consumption of sodium hydroxide, sulfuric acid and chemical auxiliary materials Larger, especially the consumption of sodium hydroxide accounts for about 40%; (2) The alkaline black liquor wastewater produced by this method is 300T / d, fibering water and flushing wastewater are about 2700T / d, and the cost of wastewater treatment is about 1.8 yu...
