Investigation of Protective Performance of Heat Resistant Fabrics under External Hot Steam Exposure
The aim of this study was to investigate protective performance of single-layer heat resistant fabrics with different air and permeability properties in particular. In order to assess its protective performance under external hot steam exposure, a steam simulating device of heat chamber was adapted for the test. Two steam pressure conditions were set: 0.5atm and 1atm. Time of second grade skin burn injures proposed by Stoll and peak temperature was used for the assessment of the protective performance, recorded by skin stimulant with sensor sitting above the back of the fabric. The gap distance between the fabric and sensor was adjustable, which was set at 0mm and 6mm for the test. The results show that air permeability, water vapor permeability, steam pressure and air thickness has effects on protective performance of the fabric in different ways. Under pressurized steam exposure, in general impermeable materials offer better protection against hot steam than permeable and semipermeable ones. Heat protective performance is a function of air permeability and water vapor permeability. There is little difference in protective performance caused by air thickness when steam pressure exists.
