In recent times, knitted fabrics made from synthetic fibres are being used increasingly for sportswear. This type of clothing should ensure thermal comfort in all weather conditions, regardless of the activity of the wearer. The most important thermal properties include thermal conductivity and resistance, as well as water vapour permeability. Sportswear often becomes wet (from sweat or due to a humid environment), which can have a signifi cant effect on thermal properties, while most testing methods only perform measurements in a dry state. This paper therefore presents our study of the thermal properties of different types of knitted fabrics in both dry and wet states. The presented research proved that wet knitwear results in a signifi cant loss of thermal comfort. This phenomenon is exacerbated when the moisture content of a material increases, and depends on the structure and filling of tested materials.
