The purpose of the present study was to investigate the heat transfer through a system of two consecutive textile layers with woven macrostructures by numerical simulation, using FLUENT CFD software package. A novel approach for modelling of the textile structure was applied, based on jet systems. The heat transfer through the systems of layers wasstudied for indoor conditions, simulating skin and indoor air temperature, as well as the effect of the convective cross flow around the human body. The results of the study showed that the heat transfer through a system of two layers is strongly influenced by the porosity and thickness of the fabrics, as well as their arrangement in the systems as aninsulating barrier between the body and the environment.
