Abstract

Cellulosic fabric was carboxymethylated by single-bath method for different durations. {Mathematical expression} arrived at a maximum when plotted against the time of reaction. This might be interpreted by the dissolution of the highly substituted fractions. The fibrous character of the carboxymethylated samples {Mathematical expression} remained unchanged, but the accessibility of the cellulose characterized by iodine sorption, porosity, and wettability changed significantly. The carboxymethylation had a complex effect on the investigated parameters: the values of accessibility were increasing initially, caused by opening the fibrillar structure, but decreasing later as the swollen structure was collapsing during air-drying. The studied properties were depending not only on the changes in {Mathematical expression} but also on the reaction parameters.
