“…It is interesting to mention that according to Sone et al [14,15] sorption isotherms of a cationic dye on partially carboxymethylated viscose rayon and on an untreated one as well, were Langmuir-type and the affinities of the dye to the modified fibers were the same as those to the untreated one. The heat of dyeing and the entropy differed not so much from the values of the untreated fibers.…”

Cellulose fabric samples were carboxymethylated for different duration. The degree of substitution was changing through a maximum value during the reaction time.The equilibrium sorption of a cationic dye by cellulosic fibers of different degrees of carboxymethylation was investigated in buffered and in unbuffered systems. The sorption isotherms were interpreted by two kinds of approximations based upon Langmuir isotherm. From the sorption data extrapolated to zero dye concentration aff'mities were calculated. The temperature dependence of affinities gave the values of heat and entropy of dyeing which were changing along the reaction time similarly to the degree of substitution.

Basic studies define the relationship between dyeability for cationic dyes and mechanical properties of chemically modified cotton fabric. Introduction of benzoyl and sulfonic acid groups provides either satisfactory dyeability for cationic dyes or color-fastness, and mechanical properties are reported as a function of the benzoate degree of substitution value. The general trend is toward increased breaking load and bending stiffness and decreased wrinkle recovery for the chemically modified fabrics, but within this trend there is latitude for selection of the degree of substituent groups to provide superior performance.

Statistically designed experiments have been made using partial carboxymethylated cotton fabric. The effects of three reaction parameters (concentrations of sodium hy droxide and monochloroacetic acid and time period) on wet pickup and carboxyl content are presented using polynomial models. Monochloroacetic acid concentration seems to be the leading factor among the parameters investigated. Poor reproducibility of the drying process could be one possible barrier to industrial applications of car boxymethylation.
