Protection against thermal hazards, such as flame, hot surfaces, radiant heat, and molten metal, is crucial for any thermal protective clothing. Among these, molten metal protection is particularly important for clothing used in foundries, welding, and other high-temperature applications involving metals. In line with this requirement, two para-aramid-based fabrics were developed: one made from 100% para-aramid and another using a blend of para-aramid, modacrylic, and steel wire (PMSS) reinforced fabric. These fabrics were evaluated for their thermal protection performance under various types of thermal exposures. Additionally, their mechanical protection performance was also analysed, as this is critical in practical applications. The results indicated that the thermal protection performance of both 100% para-aramid and PMSS fabrics was comparable, while the PMSS fabric exhibited significantly improved mechanical strength, particularly in terms of TDM cut resistance and puncture resistance. Although sticking of molten aluminium was observed for both fabric types, the addition of neoprene coating enhanced their performance against this specific exposure. Both fabrics achieved a D2 performance level as per the ISO 11612 standard, demonstrating their suitability for high-risk environments.
