As the moisture content of a fabric increases, the relative water vapor permeability (the
relative heat flow responsible for the cooling of the body) also increases and the fabric
temperature drops due to the evaporation of the water from the surface of the fabric. In this
work on the experimental study of water vapor permeability of wet fabrics, the effect of air
layers between the skin of the wearer and the fabric on the total relative cooling heat flow
(cooling effect) experienced by the skin of the garment wearer is investigated. It was found
out that when layers of 2- and 4-mm thickness were introduced between the skin and the
fabric, the relative water vapor permeability or relative cooling heat flow was smaller than
when the fabric was in direct contact with the skin, and in this case it did not depend
significantly on the fabric moisture content.
