Abstract : Solutions of selected phosphates and organophosphorus compounds were applied to cotton, viscose rayon, polyester/cotton and polyester fabrics. The glow-retardant effect was determined by burning specimens and measuring the duration of afterglow and the amount of char obtained. Phosphate ions are effective glow retardants and alkali metal ions enhance afterglow, each being about equally effective at the same ion concentration. The organophosphorous compounds studied were ineffective glow retardants. None of the compounds studied reduced the melt-dripping effect of the polyester fabric. Appreciable quantities of the most effective glow retardants were required on cellulose fabrics to give high yields of char. For these compounds, the ratio of anhydroglucose units to phosphorus atoms was approximately five to one to produce an approximately theoretical yield of char, suggesting a possible relationship to the folded-chain model for cellulose.
