Fabric Selection for a Liquid Cooling Garment

The selection of an inner fabric layer is an important aspect in the development of a liquid cooling garment (LCG). The desired characteristics of an inner fabric layer in LCGs include good thermal conductivity, moisture management, and tactile properties. Good thermal conductivity can improve cooling efficiency, and good moisture management and tactile properties can make the wearer more comfortable. Eighteen fabrics that differed in fiber content, fabric structure and thickness were investigated in this study for their suitability for use as an inner fabric layer for a LCG. Thermal resistance, evaporative resistance, wicking, and water distribution were measured. Correlation among the three moisture management tests was studied. The effects of metal-containment and fabric thickness on thermal and evaporative resistance were determined. The most suitable fabric among the 18 tested fabrics was selected in this study.
