Fabric structure has a major effect on air permeability and thermal comfort properties of apparel fabrics. Air permeability and thermal comfort properties of apparel depend on fabric structural properties such as weave type, fabric thickness, weight, yarn density and cover factor. Thermal conductivity, thermal diffusivity, thermal absorptivity, thermal resistance and air permeability should be measured to test thermal comfort properties of fabrics. The purpose of this study is to investigate the effect of the apparel fabrics structure on air permeability and thermal comfort properties. For this reason, air permeability and thermal comfort properties of viscose / polyester blended woven fabrics of different structures which are widely used in apparel have been examined. According to the results, a negative correlation was observed between weight, thickness, cover factor and air permeability of the fabrics. A positive correlation was observed between weight, thickness, cover factor and thermal conductivity of the fabric samples. A positive correlation was observed between weight, cover factor and thermal absorptivity of the fabric samples. Also positive correlations were observed between thickness- thermal resistance and thickness- thermal diffusivity of the fabric samples.
