摘要

The effect of red phosphorus was found to be effective for flame-retardancy of a pure cotton fabric.The laundered bone-dried weighed samples were impregnated with red phosphorus at suitable concentrations.Vertical flame spread test was accomplished.The optimum add-on value to impart flame-retardancy onto cotton fabric was determined around 3.95 g of red phosphorus per 100 g of fabric.TG/DTG curves of treated samples showed a well-timed weight loss occurred with regard to untreated specimens.This illustrates the sufficiency of impregnation and support its catalytic action on flame-retardancy,which is compliance with data obtained via flammability test.The resuits are in favor of "Chemical Action Theory","Gas Theory" and "Condensed Phase Retardation".
