High Quality, Multi-Purpose, Non-Toxic and Odorless Nitrocellulose Refined Cotton

Its raw material is cotton short lint, the main chemical components are cellulose, lignin and hemicellulose.
It is composed of carbon, hydrogen, oxygen 3 elements, the mass ratio of its composition: carbon 44.4%%, hydrogen 6.17%, oxygen 49.39%, its density is generally L50-L56g/cm, specific heat capacity L3O - L40kJ/ (kg·ºC), soluble in copper ammonia solution, has a good hydrophilicity and good adsorption.
General formula for refined cotton :(C6H1005) N.
N represents the degree of polymerization of cellulose, indicating the repeated basic chain in cellulose macromolecules -- glucose residues. The number of glucose residues contained in cellulose macromolecules is called the degree of polymerization of cellulose. Generally, the degree of polymerization of cotton fiber is 10,000-15,000.

Refined cotton is the main material for manufacturing ether cellulose (such as CMC, HEC, HPMC, MC, etc.), nitrocellulose (nitrocellulose) and cellulose acetate, widely used in food, medicine, daily chemical, plastics, electronics, paper making, metallurgy, aerospace and other fields, known as "special industrial monosodium glutamate".

First, the fiber is short and thick, generally only 2-3 mm, the length of only up to about 30 times the width, each cotton seed on the root number of short lint more than twice the length of the fiber, there are 2000-30000;

Second, the color is often grayish white or white, sometimes also grayish brown or grey-green;

Third, the maturity of short fleece is higher than that of long fiber, which is the reason why nutrients are easier to be transported to short fleece. The chemical composition of cotton short lint is similar to that of lint long fiber, and the cellulose content is more than 90%.
