Test Principle
Clothing is often made of materials that impede the flow of heat and moisture from the skin tothe environment. Consequently, people may suffer from heat stress or cold stress when wearinclothing in different environmental conditions. Therefore, it is important to quantify the thermal resistance and evaporative resistance of clothing materials and to consider these properties when selecting materials for different clothing applications.
