In this study, fabrics which are made of flame resistant cotton, Nomex, polybenzimidazole （PBI）, polysulfonamide （PSA）, kermel, and blend of kermei with rayon fiber are investigated on high intensity of different radiant and convective heat source. The mechanism of heat transfer in different situations is discussed. It is identified that exposed candition has an important effect on thermal protective performance. TPP rating increases with the increasing percentage of convective heat.展开更多
