Abstract

The reactivity of cotton pulp during chemical processing is significantly lower compared to celluloses obtained from other cellulose-containing plants. Increasing the reactivity of cotton cellulose improves the quality of the products based on it, and also increases labor productivity.

The aim of this work is to study the possibility of replacing wood pulp imported from foreign countries with domestic cotton cellulose by increasing the reactivity of cotton cellulose for chemical processing, improving the quality of the resulting product and increasing the reaction rate.

In this work, we used methods for determining the composition and structure of cotton cellulose samples. The reactivity of the obtained samples to acetylation after treatment with electric charges was studied. An increase in reactivity was evaluated by a decrease in crystalline areas based on diffract grams that were recorded on a computer-controlled XRD-6100 apparatus (Shimadzu, Japan). A method is proposed for increasing the reactivity of cotton cellulose by treating it with high voltage electric charges. To reduce the crystalline areas of cotton cellulose, it was activated by an electric charge, which led to an increase in the reactivity of cotton cellulose. The optimal voltage limits are found, the number of pulses and the required capacitance of the capacitor, at which the maximum values of the reactive activity of cotton cellulose are achieved.
