Dyeing Process:

A dyeing process is the interaction between a dye and a fiber, as well as the movement of dye into the internal part of the fiber. Generally, a dying process involves adsorption (transfer of dyes from the aqueous solution onto the fiber surface) and diffusion (dyes diffused into the fiber).

Methods of Dyeing:

• Bale Dyeing: This is a low cost method to dye cotton cloth.
• Batik Dyeing: This is one of the oldest forms known to man.
• Beam Dyeing: In this method the warp is dyed prior to weaving.
• Burl or speck Dyeing.
• Chain Dyeing.
• Cross Dyeing.
• Jig Dyeing.
• Piece Dyeing.

Stages of Dyeing :

• Dyeing at Fibre Stage.
• Dyeing at Yarn Stage.
• Dyeing at Fabric Stage.
• Dyeing at Product Stage.
• Union Dyeing.
• Cross Dyeing.

Basic dye in textile:

Basic dyes are water-soluble cationic dyes that are mainly applied to acrylic fibers, but find some use for wool and silk. Usually acetic acid is added to the dye bath to help the uptake of the dye onto the fiber. Basic dyes are also used in the coloration of paper.
