Cellulose ether classification code and technical requirements

Cellulose is the most abundant organic renewable resource in the world. It comes from green terrestrial and submarine plants and is the main component of plant fiber cell walls. Except for a small amount of animal bacteria and seabed organisms, cellulose mainly exists in green plants. Through photosynthesis, plants can synthesize 155Gt cellulose per year, of which 150Mt comes from higher plants; wood pulp cellulose is about 10Mt; cotton cellulose 12Mt; chemical (grade ) 7Mt of cellulose, while a large amount of wood (about 500Mt of cellulose) is still used as fuel or cloth.
Natural cellulose varies in purity. Cotton is the plant fiber with the highest cellulose content in nature, and its cellulose content is usually above 95%. Cotton long staples are traditionally used in the production of textiles. The short fiber is called Linter pulp, which is an important raw material for the industrial production of cellulose derivatives.
