FIELD OF THE INVENTION The invention relates to compositions for flame-retardant impregnation of cotton fabrics. The purpose of the invention is to increase the resistance of tissues to burning while increasing their physico-mechanical properties. The goal is achieved by using the composition for flame-retardant impregnation of cotton fabrics, which is an aqueous solution of phosphoric acid, urea and polyethylene emulsion with the following concentrations of components, g / l: phosphoric acid 100-120, urea 170-180, polyethylene emulsion 10, - 20. When using the proposed composition, the tensile load basis is 1493-1623 N; tearing load basis 69-77 N; resistance to abrasion 7000 cycles, resistance to burning 53.8-58.3 s, which significantly exceeds the physico-mechanical parameters of the fabric when using the impregnating solution of the prototype. 1 tab. ate with |
