TEXTILE EXPERTISE
MANAGE MAIN HEAT EXCHANGES
4 Main Exchange Principles:
-CONVECTION
-Characterize heat exchange through air movement
-Mainly through wind flux directly on the skin or through layers of garments
-RADIATION
-Characterize heat exchange without contact
-Infrared radiation (ex. sun heat) essentially between a hot body and cold
environment
-EVAPORATION
-Characterize heat exchange through sweat evaporation or breath
-Essentially through body sweat generation and rapid evaporation through skin or
layers of garment
-CONDUCTION
-Characterize heat exchange by contact through material structure
-Essentially through direct skin contact with garment textile structure
