Thermal decomposition of cellulose fabrics (cotton or rayon) has been investigated by thermal gravimetry (TG), differential thermal analysis (DTA), and gas analyses in relation to the effect of a flame-retardant. The fabrics became nonflammable by treating with the mixed solution (1 : 1) of ammonium bromide and diammonium phosphate. From TG and DTA, it was shown. that the flame-retardant cellulose fabrics exhibited a pronounced resistance to thermal decomposition : the decrease of the weight of the treated materials began at lower temperature and gradually continued to higher temperature; an exothermic decomposition was a little and occurred in the wide temperature range accompanied by formation of a large amount of residual charcoals and tars. Only a small amount of flammable gases such as hydrogen, methane and carbon monoxide, were produced. However, hydrogen cyanide and ammonia, which were not detected from the untreated cotton or rayon, were produced.
