Abstract:

In order to study the comfort of the firefighters' protective clothing fabrics and investigate the factors affecting the comfort of fabric combinations,11 types of fabrics commonly used in firefighters' protective clothing were selected to simulate the layered composition of fire fighting clothing, including outer shell, moisture barrier, thermal barrier and comfort lining. And the multilayer fabrics were tested and analyzed in thermal resistance, moisture resistance and total heat loss. The results show that the basic properties of selected fabric combinations meets the requirement of GA 10-2014, but heat-moisture comfort of the fabrics does not meet the American standard. The thermal resistance, moisture resistance and total heat loss of the fabric are all in line with its weight. The thermal resistance and moisture resistance increases with the weight, while the total heat loss decreases with the weight. The thickness of the air layer between fabric combinations has a greater influence on the thermal resistance of the fabric combinations. Multiple regression mathematical model was built for the water-vapor transmition rate, clo and total heat loss. It can be applied to evaluate the thermal moisture comfort of multilayer fabrics.

Key words: firefighters' protective clothing, thermal resistance, moisture resistance, total heat loss, thermal-moisture comfort
