Heat and Moisture Transfer in Clothing Systems. Part 2. Theoretical Consideration of the Effect of some Variables on Thermal Conductivity

Abstract

The theoretical effect of several variables on the total thermal conductivity of a fibrous system was determined using derived mathematical relationships. The variables examined included percentage fibre content, fibre arrangement, environmental temperature, water, ice and water vapor diffusion. It was found that the presence of water or ice greatly increases thermal conductivity, and that at practical fibre contents, minimal thermal conductivity is attained when the fibres are lying in series to the direction of heat flow.
