whats is refine cotton
Refined cotton is a white floc that is uniform and loose, free of wood chips, bamboo chips, silt,
oil, metal and other impurities.
The raw material is cotton linters, and the main chemical components
are cellulose, lignin and hemicellulose. It is composed of carbon, hydrogen, and oxygen. The mass
ratio of its composition is: carbon 44.4%%, hydrogen 6.17%, oxygen 49.39%, its density is generally
L50-L56g/cm, and its specific heat capacity is L3O—L40kJ/（kg· ℃）， soluble in copper ammonia
solution, with good hydrophilicity and good adsorption. The general formula of refined cotton:
（C6H1005）n. n represents the degree of polymerization of cellulose, indicating the repeating basic
chain segments in the cellulose macromolecule—glucose residues. The number of glucose residues
contained in the cellulose macromolecule is called the degree of polymerization of cellulose, cotton
fiber The degree of polymerization is generally 10000-15000.
Refined cotton is non-toxic, tasteless,and easy to absorb water. It is the main material for manufacturing ether cellulose （such as CMC,
HEC, HPMC, MC, etc.）， nitrocellulose （nitrocellulose） and cellulose acetate. It is widely used in
food, medicine, Many fields such as daily chemicals, plastics, electronics, papermaking, metallurgy,
aerospace, etc., are known as "special industrial monosodium glutamate".
