Abstract: A dynamic mathematical model of heat and moisture transfer through multi-layers porous textiles, in which some layers incorporate phase change material (PCM), is presented in this paper. In this model, both contact states (contact and non-contact) between each layer are considered. To numerically simulate the thermal regulating performance of the multi-layers smart thermal functional textiles/clothing, the finite volume difference scheme was used in this study. The numerical simulation was carried out for the warming and cooling processes respectively. By comparing the distribution of the temperature and moisture concentration in the each layer of porous textiles of with different add-on level of PCM and different contact states, it indicates that the thermal regulating performance of the multi-layers textile assemblies are significant influenced by the add-on levels of PCM and the contact state between each layer. The more add-on level of PCM contains in the textiles and the thicker the air layer that exists between each layer, the higher the thermal regulating performance of the multi-layers textiles will be. The numerical solution indicates that this model is satisfactory.
