Abstract

The combination of red phosphorus with boric acid was found to be effective for flame-retardancy of a cotton fabric. The laundered bone-dried weighed samples were impregnated with suitable concentrations of individual red phosphorous and/or with boric acid The fabrics were dipped into individual aqueous suspensions of red phosphorous and/or the solutions of boric acid, and some sets were impregnated with appropriate admixed solutions of the both chemicals. A vertical flame spread test was then accomplished to characterize the flammability of the specimens. An acceptable synergistic effect was then experienced by applying an admixed bath containing 0.125 formal red phosphorous and 1 molar boric acid solutions for the impartation of flame-retardancy to a cotton fabric. The optimum weight of the mixture required to impart flame-retardancy was about 8.47g anhydrous additives per 1.00g fabric. The results obtained are in favor of "Chemical Action Theory," "Gas Dilution Theory," and "Condensed Phase Retardation."
