Abstract: The thermal comfort characteristics, viz. air permeability, water vapour diffusion, wickability, absorbency and thermal insulation, of scoured and finished fabrics made from polyester-cotton MVS yarns have been evaluated. The experimental results reveal that the air permeability and the water vapour diffusion of the scoured fabrics initially increase with increasing twisting jet pressure of Murata vortex spinner and then decrease. Wickability and thermal insulation of these fabrics, on the other hand, resister a decrease initially with the increase in twisting jet pressure and then increase with further rise in twisting jet pressure. Wider nozzle distance enhances air permeability and water vapour diffusion of MVS yarn scoured fabrics but has a deleterious effect on wickability and thermal insulation. Higher cotton content is also effective in improving wickability, absorbency and thermal insulation properties but lowers the air permeability and water vapour diffusion. The chemical finishing significantly reduces the air permeability, water vapour diffusion, wickability, absorbency and thermal insulation of these fabrics.
