摘　　要：高温和低温防护服是在具有较大温差的不同环境中使用的防护性服装。为此,对常用的高温和低温防护服隔热性能的异同进行研究。结果表明:高温及低温防护服均要求具有良好的隔热性能,服装中热阻较大的区段均位于胸背、臀腹、手臂和大腿部。不同类型高温及低温防护服面料、服装整体的隔热性表现出一定差异。所使用的高温防护服主要通过阻隔环境辐射热和传导热来达到热防护目的,防护的重点在于环境辐射热。低温防护服主要通过阻隔人体内热传递来达到防护的目的。面料并不是决定高温及低温防护服隔热性能的唯一因素,防护服结构设计亦会对其隔热性能产生影响。The high-temperature and low-temperature protective clothing are used in two different environments with a larger temperature difference. This paper aims to discuss the differences and similarities of the insulation performance between commonly used high-temperature and low-temperature protective clothing. The results indicated that high-temperature and low-temperature protective clothing are both required to have good insulation performance. Sections in the chest and back, buttocks and abdomen, arms and thighs of the clothing have higher thermal resistance. Fabric and clothing insulation performance have some differences between different types of high-temperature and low-temperature protective clothing. High-temperature protective clothing achieves the purpose of protection mainly through insulating environment heat radiation and conduction, with focus on protection against environmental radiation heat. Low-temperature protective clothing, however, achieves the purpose of protection by preventing the body heat from transferring to the environment. The insulation performance of the high-temperature and low-temperature protective clothing is determined not only by the fabric, but also by the structure design of garment.
