Introduction to Indian Textile Dyes


Indian textile dyeing techniques like Bandhani (Gujarat) and Kalamkari (Tamil Nadu) represent the

rich blend of art and chemistry. These methods use natural dyes and involve chemical concepts

such as acids, bases, and salts.

Natural Dyes Used in Traditional Dyeing


- Indigo: Obtained from Indigofera plants (used in Bandhani)

- Turmeric: Used in Kalamkari for yellow shades

- Madder: Plant root used for red tones

- Henna: Natural dye for reddish-brown hues

The Role of Acids, Bases, and Salts in Dyeing


The color and fixation of dyes depend on the pH of the solution:

- Acids can change dye color or fix them to fabric.

- Bases like lime water are used in indigo dyeing.

- Salts act as mordants that help dyes bind to fibers.

Example: Indigo dyeing involves an alkaline solution and oxidation on fabric exposure.

Chemical Reactions in Dyeing


- Dye molecules bond with fabric fibers (adsorption).

- Oxidation-reduction reactions in indigo dyeing.

- Use of mordants like alum in Kalamkari changes dye binding and color.

Reaction Example: Indigo (reduced) + O2 -> Indigo (oxidized - blue color)
