摘　　要：为优化热防护服的热防护性能,将微胶囊相变材料引入热防护服中,采用改进的热防护性能测试仪,选取3种相变温度(37,43,49℃)、2种相变层放置位置、4种相变材料含量(30%、45%、60%和100%),研究不同因素对热防护服用织物热蓄积性能的影响。结果表明:相变温度为43℃、相变层放置在隔热层与舒适层之间,热防护性能相对最好;随着相变材料含量的增加,模拟皮肤发生烧伤由相变材料本身吸收热量起主要热防护作用,转变为相变材料的蓄热能力起到的热蓄积作用为主导。但考虑到成本、热蓄积性能、服装的热湿舒适性等因素,相变材料含量为45%是多层织物系统的最佳配置,其二级烧伤时间可达到224.15 s,比未加相变层的织物系统的热防护性能提高了112.12%。To optimize protective the performance of thermal protective clothing,microencapsulated phase change materials(MPCMs)were applied into the thermal protective fabric system.A modified thermal protective performance(TPP)tester was applied to assess thermal protective performance provided by these fabric system with phase change layers.In this study,three different phase-transition temperature(37,43 and 49℃),two placement location and four kinds of MPCMs with different content were selected to explore the influence of different factors on stored energy performance.Given the selected,results showed that the best thermal protective performance in this study was achieved when the phase-transition temperature of MPCMs was 43°C and the phase change layering between thermal liner and comfort liner.And with the increasing content of MPCMs,the main thermal protective effect of simulated skin burnt changed from the heat absorption of phase change material by itself,to the heat accumulation effect of the heat storage capacity of MPCMs.However,considering the factors such as the cost,stored energy,and thermal and wet comfort of garment,the best content is 45%of MPCMs,whose second-degree skin burn time is 224.15 s,increased by 112.12%compared with the multilayer fabrics without the MPCMs.
