Abstract

Cellulosic fabric composed of 84 % cotton and 16 % viscose rayon fiber was carboxymethylated. The influence of the reaction parameters (concentration of the reagents, time of reaction) on the degree of substitution was studied in the process, applying sodium hydroxide and monochloroacetic acid in one bath. Two kinds of regression equations were used to calculate approximately the degree of substitution. These polynomials can be used for the selection of reaction parameters to obtain a sample of a given degree of substitution.
