Dyes are coloured substance that has an affinity to the substrate where it is applied. Dyes are usually used in an aqueous solution requires a mordant to improve the quickness of the dye on the fiber materials.
Dyes are coloured because they absorb wavelengths of light preferentially. Unlike Dyes, pigments are insoluble substances that have no affinity for the substrate.
Republic of Georgia found Dye Fibres before centuries in a prehistoric cave. Researchers have learned that India has been extensively exploring dyes and pigments for over more than 5000 years back. The Dyes are found from vegetable, mineral and animal.
Dyes are the greatest source derived from roots, plants, berries, leaves and wood; but these are less used on commercial basis.
Types of Dyes:
- Synthetic Dyes
- Acid Dyes
- Direct or Substantive Dyes
- Disperse Dyes
- Reactive Dyes
- Carbene Dyes
- Sulfur Dyes
- Organic Dyes
- Basic dyes
- Vat Dyes
- Mordant Dyes
- Food Dyes
- Solvent Dyes
In today?s society, people are more inclined towards using natural fibres and natural colours with the current increase in the environmental awareness. Indeed, the Soil Association says on their website that their standards for organic goods allow the use of natural dyes only.
