摘要：
A model of heat and water transfer through layered fabrics, such as clothing worn, is developed in this paper. All particular properties of recent fabrics are considered : hydrophobic or philic treatment, membranes stuck on a layer, surface modification of textile (scratching). The physical phenomena taken into account are : sorption or desorption; free water condensation or evaporation, liquid, vapour and adsorbed water diffusion; heat conduction; contact resistances between layers. The model is dynamic for one dimensional transfers. Considering this particular porous medium, the energy and mass balance lead to a system of two differential equations (moisture, temperature). Some simulations are carried out with a two laver clothes set.
