  1. Fabric Material Properties Aaron Packard Me En 340 Heat Transfer 16 April 2007

  2. Body uses evaporative cooling for temperature regulation Jersey material influences the effectiveness of evaporative cooling Influential factors Material conduction coefficient Fabric weave and pattern Moisture wicking capabilities Compared Cotton to Polyester Introduction

  3. Calculated convective heat coefficient for free convection Thermal conductivity of fabric varies with: Material Weave and fabric pattern Moisture content Heat generation of body is dependent on current metabolic rate Heat Transfer Problem

  4. Difficulty of modeling Experimentation Measure body surface temperature Warm up with heart rate at 153 bpm Stop at steady state surface temperature Cool down with fan Solution

  5. Shirt Less wicking of moisture causes perspiration to remain closer to the skin and reduces the amount of heat that can be transferred from the surface through evaporative cooling. Jersey Better breath-ability Wicks moisture and diffuses it over a greater surface area allowing for more effective evaporative cooling. Results and Conclusions
