Evaluation of Thermal Performance of Flame-resistant Fabrics Considering Thermal Wave Influence in Human Skin Model
A thermal wave skin model incorporating surface heat flux from a skin simulant sensor is developed to characterize the thermal performance of flame-resistant (FR) fabrics covering the skin simulant sensor. Comparison of the results of time to 2nd degree skin burn and temperature elevation of skin beneath a layer of fabric obtained from the newly developed thermal wave skin model to the results obtained by using the Pennes' equation is performed in this research. Results of tolerance time from Stoll criterion method are also compared with Henriques burn damage integral from two skin models between constant–flux exposures in TPP calorimeter. Investigations have been conducted to find the effects of structural parameter, air pressure, and air layer thickness on the thermal performance of the selected FR fabric determined by the newly developed skin model and the method. It is concluded that the thermal protective performance of FR fabrics can be characterized here more precisely than in previous work.
