Calculations of Heat and Vapour Transport in Clothing: Transient Effects in Hygroscopic Materials

Abstract

A numerical model of heat and water-vapour transport through multi- layered clothing systems under transient conditions is presented. Taken into account are the condensation and evaporation of liquid water within the clothing layers and changes in the amount of water absorbed by hygroscopic fibres although the hygroscopic properties are taken to be a very simple form. The calculations are compared to experiments reported by Woodcock in 1962, giving good agreement, and used to discuss the so-called buffering effect of hygroscopic clothing materials.
