Studies on Indigenous Cotton linters for Preparation of Carboxymethyl Cellulose

Abstract

Studies were carried out to find out a suitable method for preparation of carboxymethyl cellulose (CMC) from indigenous cotton linters. Special emphasis was given on purification method to remove most of the non-cellulosic materials. A twostep purification method of cotton linters for preparation of water soluble carboxymethyl cellulose (CMC) with degree of substitution (DS) 0.89 and viscosity 235 cp (0.5 % solution) have been described.
