The reactivity of cotton pulp during chemical processing is significantly lower compared to celluloses obtained from other cellulose-containing plants. An increase in the reactivity of cotton cellulose improves the quality of the resulting product, and also increases labor productivity.

The aim of this work is to increase the reactivity of cotton cellulose for chemical processing, improve the quality of the resulting product and increase the reaction.

In this work, methods were used to determine the composition and structure of cotton cellulose samples. The reactivity of the obtained samples to acetylation was studied.

The increase in reactivity was evaluated by the reduction of crystalline regions based on diffractograms that were recorded on an XPD-6100 controlled computer instrument (Shumazu, Japan).

A method is proposed for increasing the reactivity of cotton cellulose by treating it with high-voltage electric charges, in which crystalline regions sharply decrease, which reduce the reactivity.

The following optimal activation parameters of cotton cellulose were found: voltage - 11-13 kV; the number of pulses - 22-24; required capacitance - 0.6 μF.

Thanks to the use of this method, it was possible to increase the reactivity of cotton cellulose to chemical processing, in particular to acetylation. This allowed us to improve the quality indicators of cellulose acetate, increase the productivity of the finished product due to improved filtration of cellulose acetate.
