Thermogravimetry (TG/DTG) of the pure cotton and the treated one with the above-mentioned sulfate as well as for pure salt were also accomplished and their TG curves were compared and commented to detect the combustion’s pathway of the supported substrate.
TG data confirm major mass loss in treated cotton. It occurred well below at a punctual duration of the thermal degradation
zone of the polymer.
So fewer flammable volatiles and more char could be produced during combustion.
The results obtained are in compliance with gas dilution theory and also chemical action theory.
