Too many insecticides and chemical fertilizers used to foster the cultivation of cotton have made a great harm to the earth environment. However, during the process of cultivating organic natural cotton, insecticides and chemical fertilizers are both forbidden to use. The land must be under cultivation for at least three years while seeds must never be processed by bactericides. During the period of growth, insecticides and weed killers are both forbidden to use. Furthermore, the weaving and dyeing processes are organic and environmental as well; not any fluorescent brightening agent, formaldehyde, benzene, chlorine, heavy metal, medicament or dye can be added into the textiles.
