Increasing Reactivity Cotton Cellulose Intended For Acetylation

Abstract

Cotton fiber is crimped in nature, therefore, in dry and wet conditions, they quickly gather into lumps and nodules, forming flagella and ropes, as well as enveloped with weed impurities and become difficult to clean.

Due to the above specifics, cotton fiber requires additional mechanical processing - chopping, chopping, etc. For fiber grinding, rolls, conical and disk mills are mainly used [1].

A number of works [2-3] provide descriptions of various methods of cleaning lint, boiling, etc. in order to obtain uniformly pure cotton cellulose intended for chemical processing and for acetates, nitrates and other cellulose ethers.
