In both case final color is developed by the oxidation process. Although, reactive dyes, azoic color is available but sulphur dyes is preferable for black shade production. Dye, are classified according to the application method. Some of the examples of dyes are acid dyes, basic or cationic dyes, direct dyes, sulfur dyes, vat dyes, reactive dyes, mordant dyes etc. Colorants and auxiliaries will remain the biggest product segment, while faster gains will .
