Textile Dyeing

Fixing Agents: Depending on the type of dye used, fixing agents like salt, alkalis, or reactive agents are used to ensure the dye adheres to the fabric.

Mordants: These are used in dyeing processes that require them, such as natural dyeing. Common mordants include alum, iron, and chrome.

Auxiliaries: Various auxiliary chemicals are used to improve the dyeing process, such as leveling agents to ensure even dye uptake, wetting agents to improve dye penetration, and dispersing agents for disperse dyes.

Acid and Alkali Regulators: These chemicals help in maintaining the pH of the dye bath, which can be crucial for some dye types.

Antifoaming Agents: To control foam formation during the dyeing process.

Sequestrants: Used to chelate metal ions that might interfere with the dyeing process.

Optical Brighteners: These are used to enhance the whiteness and brightness of fabrics.
