Abstract:

The goal of this study was to examine whether there is a correlation between the moisture content in fabric and the thermal resistance thereof. Denim fabric made of five different compositions of fibre content was used for testing thermal resistance under dynamic moist conditions. An ALAMBETA semi-automatic non-destructive thermal tester was used to check the thermal resistance. A mathematical equation was developed for prediction of the thermal resistance of denim fabric submersed in water at different moisture levels. This model is based on the relationship between the density ratio of the fibre and fabric, the thickness of the fabric and the amount of moisture therein. A number of simulations were tried and finally one arrangement found that has significant agreement with actual values. This model can be used for other types of fabric because there is no role of the geometry of fabric in it. The model proposed exhibits a substantial link with the experimental data.
