The plants used in Anatolia for centuries have shown diversity due to the differences in the geographical structure of Turkey. This diversity is important for plant dyeing.The aim of this research to dye the cotton, wool and silk fabrics by dyeing fresh and dry leaves of indigo plant used in vegetable dyeing and determine the light, rubbing and washing fastness of the colors obtained from the dyeings. Dyeing prescriptions were prepared for using in the dyeing process of indigo plant. In the dyeing process, 36 dyeing were performed using alum, copper sulfate, iron sulfate, sodium hydrosulfite and sodium hydroxide mordants and also without mordants. Light, rubbing and washing fastness of fabrics were measured and evaluated after dyeing process. Fastness measurements of the colors obtained were carried out in the chemistry department laboratory of Istanbul University Engineering Faculty. Light, washing and rubbing fastnesses of cotton, wool and silk fabrics are available at the desired level and as a result of dyeing process with indigo plant.
