Relationship Between Thermal & Dampness Resistance and Comfort Wearing

There are three main aspects of clothing comfort performance, thermal wet comfort, contacting comfort and visual comfort. Thermal comfort is the most important performance and must test through a professional Sweating Guarded Hotplate. Contacting comfort and visual comfort can test through the human body touch and also evaluated by wearing and sensory. 80% of the energy consumed by human activities will be converted into heat, and 90% of this energy should be distributed through the skin. Therefore, the thermal resistance of textile materials to maintain body temperature has an imperative impact.

Also, using radiation, conduction, and convection to help human body cooling, it also can evaporate the heat through the body surface sweat, where water vapor can cause diffusion into the environment through the clothing system timely so that people would feel comfortable. If the clothing hindered by water vapor, and the humidity in micro-climate increased between the human skin and clothing, people would feel uncomfortable. Clothing thermal insulation and water vapor through the performance of the human body and the environment during heat exchange process play an important regulatory role. Therefore, the evaluation of these two indicators can predict the textile in different environments of the thermal physiological comfort.
