Abstract: A novel perspiration imitation thermal manikin is developed to measure the thermal resistance and moisture vapor resistance of fabrics.The traditional guarded hot plate apparatus can be used to measure the thermal conductivity of various textiles.Measurement of thermal resistance of a series of shirts and the related fabrics are carried out with the above two apparatus.The data shows that these two apparatus all have high accuracy and reproducibility.However,the thermal resistance of fabrics with air layer measured by the guarded hot plate apparatus is less than that by the thermal manikin.
