Abstract

The aim of present work was to use waste cotton fiber from the textile industry as a raw material and extract cellulose to prepare carboxymethyl cellulose from it by adapting a modified etherification methodology. Cotton waste fibers are an abundant waste, but it has great potential for use as a cellulose source for the production of carboxymethyl cellulose (CMC). The chemical composition of Egyptian cotton fibers, such as cellulose, sugar, and waxy matter was determined. Scouring and bleaching pretreatments were used to prepare the cotton samples. Then cellulose extracted was carboxymethylated using sodium hydroxide and monochloroacetic acid in aqueous ethanolic medium using different concentration of sulfuric acid. Carboxymethyl cellulose was characterized using Fourier transform infrared spectroscopy (FTIR). Results confirming the transformation of cotton fiber waste to carboxymethyl cellulose.
