A common metric of assessing the evaporative cooling potential of ,protective clothing, is to assess the rate of diffusion of water vapour through the fabric. Another mechanism that supports evaporative cooling is convective transfer. Prototype porous coveralls were constructed to promote convective air flow with 0.0024 mm (0.06 inch) holes representing nominal openings of 0, 1, 2, 5, 10 and 20% ...

Effect of Fabric Deformation on Thermal Protective ...

Fabric deformation led to a significant reduction of the predicted ,thermal protective, performance of fabrics, mainly due to changes in fabric thickness, ,porosity,, and mass per unit area. Predicted skin burn times decreased for increasing stretching forces, although the decrease was less pronounced under high-intensity heat exposure as a result of fabric shrinkage and degradation.
