Ozone,composed of three atoms of oxygen,can be used to oxidize many inorganic and organic impurities.Because of its high oxidizing capacity,the opportunities and parameters of ozone gas use in bleaching of cotton fabrics were researched in this study.It was found that in a very short time cotton fabrics can be bleached if the water content of cotton-woven fabric was 60% and the pH of the water impregnated was 7.Moreover,ozonation at room temperature was shown to be more efficient than ozonation at high to medium temperatures.
