Abstract
The objective of present study was to investigate the effect of bilayer coating of different concentrations of ammonium polyphosphate (APP) and casein on thermo-oxidative properties, flame retardant behavior as well as thermal conductivity of char residues of cotton fabrics. Intumescent flame retardant coating, composed of cationic casein and anionic ammonium polyphosphate has been constructed on cotton fabric by bilayer coating. The flame retardant behavior was found to increase predominantly with increase of APP concentration than the casein concentration due to greater release of phosphoric acid and ammonia from APP. Whereas, the higher concentration of casein was found more advantageous to form the distinct layer of intumescent char formation, where cotton fabric samples coated with 15% casein and 7.5% APP contents produced maximum char of 44%.
