Abstract
The effect of nickel sulfate hexahydrate (NiSO·6H O) on the flammability of cotton fabric was investigated and the 4 2 optimum add-on value of nickel sulfate for imparting flame-retardancy to cotton fabric was calculated (as 11.8-14.3 g anhydrous salt per 100 g fabric). Thermogravimetric analyses of pure cotton, treated cotton and pure salt were accomplished, and their thermograms were compared. The results obtained agree with the Gas theory expressing water expulsion over a certain duration of the thermal degradation zone of cellulose. In fact, this occurs over a desirable range, prior to the initiation of cellulose thermal decomposition.
