Mostly all clothing undergoes many washings cycles during its useful life. It can alter the fabric dimensions, weight and cover factor which may ultimately affects the heat transport properties with other important properties. In this paper the impact of repeated washings on the thermal insulation properties of woven cotton fabric was studies. Result reveals that thermal insulation values of washed sample were decreases after repeated washings.
