摘要： 现阶段消防灭火服热防护性能评估中，对水分影响的考虑不足。为研究水分在不同织物层中对其热防护性能的影响差异，在低热辐射暴露下，分别在外层、舒适层、外层与舒适层设置不同含水量水平，分别针对直接热暴露、包含热暴露与蓄热释放全程两种情形进行试验测评。研究发现，无论是直接热暴露还是综合考虑蓄热释放的作用，增加外层织物水分含量有利于提升多层织物整体热防护能力，且随着水分含量的增大而上升；舒适层织物润湿则会削弱多层织物整体热防护能力，提高舒适层的吸湿排汗能力，保持其干燥是保持灭火防护服热防护性能的手段之一。外层与舒适层同时润湿时，二者之间呈现交互影响，未来可进一步深入研究。

Abstract: In the current evaluating thermal protective performance of firefighter protective clothing, the effect of moisture is ignored. Aiming to study the different impact of moisture in different fabric layers on thermal protective performance of fabric system, the different water contents were set in outer layer and comfort layer, experimental study with direct thermal exposure as well as with whole process of thermal exposure, heat storage and release were conducted under low-level radiant heat exposure condition. The results demonstrate that increasing moisture content of outer layer is beneficial for improving thermal protective performance of multi-layer fabric, in addition, with increasing moisture content, thermal protective performance is also the same, whether it is direct thermal exposure or considering the effect of heat storage and release. However, wetting comfort layer weakens thermal protective performance of fabric system, besides, the effective measures to improve thermal protective performance are to keep dry, increase moisture absorption and sweat releasing of comfort layer. When outer layer and comfort layer are simultaneously wetted, there is an interactive effect between the two, which can be deeply studied in the future.
