Technical requirements: chemical fiber technology: in addition to cellulose fiber composition, there are pectin, hemicellulose, lignin, fat and water soluble substances such as non cellulose with biomass, collectively referred to as the glial. In the textile production, the need for raw materials for chemical degumming forming white line, and then use the spin again. Spin the number higher, more high of flax degumming technology, and market prices also increased. Pectinase / sodium sulfite degumming currently used in the company, after cleaned with hydrogen peroxide, can get the highest 80 pieces of linen. We need good chemical degumming technology, get a higher number of linen.
