The results of studies of fire - resistant impregnating compositions based on an aqueous solution of polyvinyl alcohol and an antipyretic additive-methylphosphite borate are presented. The effectiveness of single-stage processing of cotton threads with these impregnating compositions has been proved. It is established that the developed impregnating compositions for cotton threads have shown high efficiency of thermal and fire-retardant action. The influence of the developed impregnation formulations on water absorption and strength of cotton threads was evaluated.
