A mathematical model, which describes coupled heat and moisture transport, investigated coolness to touch in woolen fabrics. Subjective coolness to touch was related to the hygroscopicity of the fabrics. Measurements of the temperature changes occurring at the interface between the skin and fabric confirmed the preductions of the model. Thermal changes associated with the desorption of small amounts of moisture during skin touch caused the temperaure of wool fabrics to rise more slowly than that of less hygroscopic fabrics. 15 refs.
