Abstract:	Purpose – The purpose of this paper is to present a dynamic analysis on the thermal and electrical properties of fabrics under wet conditions. Design/methodology/approach – A purpose-built apparatus is applied to test the thermal and electrical properties of textiles in moisture absorption and liberation process. Relation between temperature and resistance of a cotton/polyester double-layer fabric is also analysed. Findings – The surface temperature of textiles shows three different stages in the process. The electrical resistance is linearly related to the reciprocal of the moisture regain of fabrics. In the moisture absorption and liberation process, surface temperature of cotton layer is higher than that of polyester layer. And the electrical resistance of cotton layer decreases more quickly than that of polyester layer. The electrical resistance changes earlier than surface temperature in the moisture-liberation process. Practical implications – The paper is helpful in not only the designing of sportswear, but also the devising of moisture-testing apparatus. Originality/value – A dynamic testing method is applied to characterize the thermal and electrical properties of textiles.
