Dynamic and a static methods for measuring thermal conductivity of textiles have been developed, and the measuring processes and results are described in detail in this paper. Three different textile materials are used for the actual test, and the data are. analyzed, illustrated, and compared. Moreover, a theoretical model is used to obtain the temperature-time curves as predictions corresponding to the dynamic method, and comparisons of the theoretical predictions and experimental results are provided. The static and dynamic methods are also compared, and their applicability to porous media like textiles is discussed.
