Nonlinear property on coupled heat and moisture transfer in clothing ergonomics system

The thermodynamic method was applied to ergonomics system of human body-clothing-environment. The coupled heat and moisture transfer in clothing was described by the relation between thermodynamics strength and thermodynamics flow in non-equilibrium thermodynamics system. Sweating manikin equipment was used to obtain nonlinear relation of coupled effect. The data of measurement explain that the coupled effect in clothing should not be neglected.
