Due to "insensibilis perspiration" process of the human body, the textile materials for the garment products, must have vapour permeability. In order to feel the thermo physiological comfort during clothing wear, the vapour permeability values must be correlated with the environment, the body conditions and factor related to the fabrics (finishing treatments, structure, raw materials).Vapour permeability capacity through fabrics are important properties of fabrics that influence the comfort of thermo-physiological products for apparel products. Chemical finishing processes applied to textile materials can improve or reduce the vapour permeability capability depending on the destination. Textile dyeing and film finishing processes influence the vapour permeability and implicitly, the other thermophysiological comfort features (air permeability, thermal insulation) that determine the use of a textile fabric.The paper presents the results of the researches realized on samples of fabrics with different structures, made from polyester yarns in the warp system, with different length densities. The purpose of the research is to emphasize the influence of chemical finishing processes (dyeing and waterproofing through film coating) on vapour permeability values. The experimental values obtained for vapour permeability as well as the calculated coefficients of vaporization, as a direct indicator of this thermo physiological comfort feature, have allowed the determination of the range of use of the analysed fabrics.
