摘　　要：防火服在火焰中的收缩形变会影响其热防护性能并制约人体的肢体运动。为此,提出用捺印的方法,通过燃烧假人闪火燃烧试验,研究防火服各部位形变量的分布规律,探究形变差异的原因及影响因素,对比分析服装形变与假人皮肤表面烧伤程度的关系。结果显示,燃烧试验后防火服在四肢和背部发生了显著收缩形变,热流量、衣下空气层等是主要影响因素。着装姿势越复杂、闪火持续时间越长,服装越宽松,服装面料的面密度越大,服装形变越显著,服装形变显著的对应部位衣下皮肤的烧伤也越严重。The shrinkage of fire-fighting suit in the flame may affect its thermal protective performance and constrain body＇s movement. By using an instrumented mannequin, flame-test for complete garments is applied to simulate the fire situation. Seals marked on the garment are used to measure the shrinkage distribution of the garments during flash fire exposure. The reasons for the shrinkage and its factors are studied. The relationship between shrinkage and the burn injury of manikin skin is preliminarily analyzed. Results show that the sleeves, trousers and the back of the clothing shrink significantly. The variation of the shrinkage results from the heat flux, air gap and other factors. The shrinkage extent is influenced by wearing posture, fire duration, construction size, and fabric areal density. As a whole, burn injury will be more serious where the shrink is more significant.
