Developing a test device to analyze heat transfer combined with radiant exposure and continuous liquid sweating through thermal protective clothing

Human perspiration significantly affects heat and mass transfer in clothing systems absorbs thermal energy on the skin, especially radiant exposure high-intensity work. However, few testing devices simulate human sweating for assessing under radiation exposure. Thus, a test device that could realistically specific sweat rates was developed to evaluate influence of continuous protective performance (TPP). The TPP single-layer fabrics at dry (No-sweating) three constant studied based calibrated tester. It indicated new apparatus effectively evaluated fabrics’ wet properties. Furthermore, compared sweating, traditional pre-wet method may overestimate fabric depending rates. played dual role second-degree burn time absorbed energy, which is related moisture management fabrics. research provides an effective characterize materials sweating/wetting, will help optimize update relative standards.
