Abstract:

As industrial workers may be threatened by hot water splashes, the study investigated the heat transfer of fabric upon hot water splashes. The orthogonal experiment was designed to test performance of 11 kinds of fabrics under conditions different water temperatures, splash angles and splash heights. The experiment was conducted by a hot water protective performance tester, and the 2-grade burn time was adopted to characterize the thermal protective performance of fabric. The effects of the fabric property and splash condition on the thermal protective performance were analyzed. The results show that water-proof finish can improve the thermal protective performance of fabric. The splash condition and fabric peoperty influence the thermal protective performance in different position of fabric. The temperature of hot water is the most important factor influencing the thermal protective performance. The thermal protective performance of upper position of fabric is primarily related to the splash condition. The protective performance of the lower position is influenced mostly by the fabric property.
