Thermal Protective Performance of Heat and Flame Resistant Fabrics in Different Radiant and Convective Heat Exposures

【摘要】 The thermal protective performance (TPP) is important for heat and flame resistant fabrics. In this study, fabrics which are made of flame resistant cotton, Nomex, polybenzimidazole (PBI), polysulfonamide (PSA), kermel, and blend of kermel 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 condition has an important effect on thermal protective performance. TPP rating increases with the increasing percentage of convective heat.更多还原
