Abstract: In order to understand and evaluate the thermal wet comfort performance of the lining of firefighter protective clothing, and to provide reference for their design and development，the thermal wet comfort performance of six types of lining commonly used for firefighter protective clothing in service was tested, and the comprehensive thermal wet comfort performance of the six types of lining for firefighter protective clothing was evaluated by using grey comprehensive evaluation, the degree of influence of each factor on the comfort was analyzed by using grey relational analysis. The results showed that the fabric with a bulging tubular structure, imported stoste Nomex fibers and high-performance flame retardant fibres, warp density of 375 roots/10 cm, weft density of 490 roots/10 cm, areal density of 140 g/m2, and thickness of 1.79 mm has the best comprehensive performance in terms of thermal wet comfort performance, with a premium degree of 0.958, which is the closest to 1. The air permeability has the greatest impact on the thermal wet comfort performance among the 8 test indexes for the fabrics. The relevance of the 8 test indexes to the premium degree is around 0.8, which is not much different. The thermal wet comfort performance of the lining of firefighter protective clothing is mainly related to the fabric structure, tightness, thickness and areal density.
