Written by Acid dyes are water-soluble, anionic dyes that require an acidic environment to bond with fibers. They are primarily used to dye protein fibers like wool, silk, and nylon, producing bright and vivid colors with good lightfastness and wash fastness. Acid dyes are not suitable for cellulose fibers like cotton. They work by forming ionic bonds with the basic (cationic) sites in the fibers, and are commonly used in the textile, leather, and food industries.
How Many Type of Acid Dyes?
Acid dyes are classified into several types based on their dyeing properties, leveling characteristics, and chemical structure. The main types of acid dyes commonly recognized in the textile industry are:
Leveling (Self-Levelling) Acid Dyes: These dyes have good leveling properties and are used for even color distribution but have lower wash fastness.
Milling Acid Dyes: These offer better wash fastness and are suitable for wool and silk; they are also known as neutral acid dyes.
Super Milling Acid Dyes: These have very high fastness to milling and are used where superior durability is required.
Metal Complex Acid Dyes: These dyes form complexes with metal ions, providing a wide range of shades and improved fastness.
Fast Acid Dyes: Known for their high light and wash fastness, suitable for textiles exposed to demanding conditions.
Equalising/Levelling Acid Dyes: Designed for uniform coloration, especially important for solid-colored fabrics.
Additionally, acid dyes can be classified by the acidity required in the dye bath:
Strong Acid Dyes
Weak Acid Dyes
Neutral Acid Dyes
These classifications help manufacturers and dyers select the appropriate dye type based on the fiber, desired colorfastness, and application process.
