[0002] Refined cotton is a white flocculent material that is uniform and loose, free of wood chips, bamboo chips, sand, oil, metal and other impurities. Its raw material is cotton linters, and its main chemical components are cellulose, lignin and hemicellulose. It is composed of three elements: carbon, hydrogen and oxygen, and is soluble in copper ammonia solution. It has good hydrophilicity and good adsorption. Refined cotton is non-toxic, tasteless and easy to absorb water. It is the main material for manufacturing ether cellulose, nitrocellulose and cellulose acetate. It is widely used in food, medicine, daily chemicals, plastics, electronics, papermaking, metallurgy, aerospace and many other fields. It is known as "special industrial monosodium glutamate".
