Abstract
The present work was aimed to develop the flame retardant textiles for prevention of second-degree burn injuries
from low intensity heat flux accidents. The different concentration of casein suspension was applied on cotton fabrics and
their thermo-oxidative properties, flame retardant behavior as well as physiological comfort were examined. From thermo
gravimetric analysis, the percentage increase in char residue indicated improvement in thermo-oxidative properties. The
maximum improvement in flame retardant behavior was found in case of 30 w/v % casein suspension due to higher
production of thermally stable char. Their SEM micrographs also showed the formation of stronger and coherent char with
presence of local intumescence. Furthermore, for estimating small differences in burn length and burn area, the flame
propagation was studied in detail using the image analysis. The lower concentration of casein below 20 w/v % was found to
provide adequate flame retardancy with acceptable physiological comfort and mechanical properties. Finally, the short term
durability of casein treatment was verified under the effect of washing and ageing conditions.
