Background. 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 to chemical processing improves the quality of the resulting products based on it, as a result, labor productivity increases. Purpose. Replacing wood pulp imported from foreign countries with domestic cotton cellulose by increasing the reactivity of cotton cellulose to chemical processing, improving product quality and increasing the reaction rate. Methodology. 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 diffractograms that were recorded on a computer-controlled XRD-6100 apparatus (Shimadzu, Japan). Originality. A method is proposed for increasing the reactivity of cotton cellulose by treating it with high-voltage electric charges. Findings. The optimal voltage limits of 11-13 kV, the number of pulses 22-24, the capacitor capacitance of 0.6 μF were found, at which the maximum values of the reactive activity of cotton cellulose were achieved. Key words: . Highlights: - processing of cotton cellulose with an electric charge; - hydration of cotton cellulose with electrolyte;
