The paper consider heat and moisture transport within cotton fabric exposed to fire as drying process. A mathematical model of simultaneous heat and moisture transfer is proposed for the prediction of temperature distributions during high heat flux condition based on the theory of drying. Shrinkage occurring in the drying zone was incorporated into the present numerical model. Using the model, we will can understand the drying mechanism and process of flame retardant cotton fabric used for thermal protective clothing. The discrete calculation and experiments will be presented in the further study.

Hygrothermal Behaviour

Heat and moisture transfer in a room is critical for the indoor comfort.This first chapter introduces the basic concepts of heat and moisture transfer in buildings, dealing with the main theoretic fundamentals.It focuses on the most common parameters, used to analyze heat and moisture transfer in buildings.Furthermore this section takes into account a numerical model to calculate the simultaneous heat and moisture transfer in building materials.It is demonstrated that both the microstructure and physical parameters, e.g. density and porosity, may influence greatly the hygrothermal behaviour of the building materials. This is the reason why this chapter also gives prominence to the porous materials.
