FIBROUS CARBOXYMETHYLCELLULOSE BY PAD ROLL TECHNOLOGY

Statistically designed experiments have been made using partial carbox ymethylated cotton fabric. The effects of three reaction parameters (c oncentrations of sodium hydroxide and monochloroacetic acid and time p eriod) on wet pickup and carboxyl content are presented using polynomi al 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 applicatio ns of carboxymethylation.
