Determined the content of metal ions in the naturally green cotton by means of ICP. Results show that the fabric hue changes greatly after the treatment of EDTA, different time, temperature and concentration of EDTA hardly affect the hue of the fabric, and the content of metal ions decreases with the treatment of EDTA, which result in the color change of the naturally green cotton..
