Heat and mass transfer through the garment on wearer's body is affected by the change in the air gap thickness and the contact area more than by the material of the fabric. For thermally relevant evaluation of the thermal properties of clothing, e.g. during work or leisure time, it is important to analyse the air gap thickness and the contact area for prolonged, stationary and ergonomically correct body postures. A flexible manikin, which has similar body size and flexibility of joints as an adult male, was used to mimic realistic human body postures (standing and driving). To obtain accurate and reliable 3D scans, stands with fixations and the garment with easy openings were designed and Artec MHT 3D scanner was used. The presented study indicates that the distribution of air gap thickness and contact area between the body and the garment was depended on the posture of human body due to the gravitational force and the pressure from the chair on the flexible garment. The results of this study can contribute to an improvement of clothing design for functional garments and can be applied to heat and mass transfer modelling in clothing for various postures.
