Applications and industries for refined cotton
Refined cotton is a kind of cellulose refined from cotton linters as raw materials requires deep process knowledge — from alkaline pulping, bleaching, drying and refined process. The cotton linters has high maturity, refined cotton made by the cotton linters has high alpha cellulose content,
etherification reaction to reduce polymerization degree in small amplitude.

Refined cotton is the main material for the manufacture of ether cellulose (such as CMC, HEC, HPMC, MC, etc.), nitrocellulose and cellulose acetate.
The products are widely used in food, textile, cellulose ether, building materials, medicine, chemicals, plastics, electronics, military, paper making, metallurgy, aerospace and many other fields.
Solutions for refined cotton processing
Characteristic
Characteristic for refined cotton processing
Opening cotton linters process: requires the preliminary solution before cooking process, from air conveying, alkali spraying, pressing, and conveying process, achieving more uniform quality during high temperature cooking process.
Cooking process: alkaline cooking requires removing all kinds of impurities destroyed in the cooking process and improve the moisture absorption of the product.
Washing process: softened water process and counter current washing process for saving water.
Bleaching process: for multi-stage bleaching process which improve the whiteness of the product and the uniform of polymerization.
Drying process: requires the dewatering squeeze and air drying process.
Benefits of our professional solutions for refined cotton processing equipment
