Diffusion of Water Vapour Through Cold Gore-Tex(trademark)
Abstract
A simple gravimetric procedure was devised to measure the water vapour diffusion resistance of waterproof, water vapour permeable textiles at temperatures below freezing. The apparent resistance of a hydrophilic film, part of a Gore-Tex(TM) laminate, increased exponentially with a decrease in temperature. At sub-zero temperatures, water vapour transfer through this film was only a few percent of what it is at room temperature. The diffusion process in such materials is discussed. other hydrophilic films are likely to be similarly affected.
