Abstract:

In order to investigate the influence of air gap between fabric layers and human skin on protective performance of protective clothing against steam, three different fabric systems were selected and four levels of air gap, i.e., 0 mm, 6 mm, 12 mm, and 18 mm, were designed. Time to 2nd and 3rd burn degree, total absorbed energy and heat flux were recorded and analyzed to evaluate the impact of air gap on the protective performance. The results show that thermal protection is different for different fabric assemblies. If the fabric thickness is bigger and moisture barrier is arranged more close to the steam hazard, the fabric system provides higher thermal protection. Further, a significant relationship exists between the thermal protection against steam and air gap size. If the air gap size is higher than 12 mm, thermal protective performance against steam exhibits a significant increase. The analysis of heat flux curve during exposure and cooling phase can facilitate the further understanding of the heat and moisture transfer mechanism.

Key words: thermal protective clothing, air gap, steam hazard, protective performance, total absorbed energy
