This paper reports on an investigation of physical properties on some of the clothing comfort properties of knitted fabrics. Fabric parameters such as fabric density, fabric thickness and fabric weight have been considered to be correlated to air and water vapor permeability, and also moisture management properties which includes accumulative one-way transport index and overall moisture management capacity. This is important in order to determine the overall thermophysiological comfort performance of knitted fabrics. The results suggested that all of the fabric parameters stated before appeared to affect the fabric comfort properties.
