Comparison of heat insulation performance between commonly used high-temperature and low-temperature protective clothing

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.
