1. Acid Dyes
The acid dyes are type of dyes that contain chemical groups called sulfonic or carboxylic acid, which help them bond with fibres during the dyeing process. These dyes are applied to the fibers from an acid solution. Only fibers which develop a positive charge in the presence of acid, such as wool and other protein fibers, nylon, and certain modified synthetics, are readily dyed by acid dyes.
2. Basic Dyes
These dyes are water-soluble colors made from organic compounds and salts. They’re mostly used for colouring acrylic fibers. Acetic acid is often added to the dye bath to help the dye stick better to the fibers. The basic dyes are commonly used to colour items like paper, jute, detergent, and soap, etc.
3. Direct Dyes or Substantive Dyes
These dyes are normally carried out in a neutral or slightly alkaline dye bath, at or near boiling point, with the addition of either sodium chloride or sodium sulfate or sodium carbonate. Direct dyes are used on cotton, paper, and cellulosic fibers. They are also used as pH indicators and as biological stains.
4.Solvent Dyes
Solvent dyes, also known as solvent-soluble dyes, are specialised dyes designed to dissolve in organic solvents rather than water. They offer unique features and properties that make them highly versatile and desirable for various applications. Solvent dyes are used to dye paper specially craft papers. Purified form of solvent dyes is used in Cosmetic industry as well.
5. Intermediate
Dye intermediates are chemical compounds used in the production of dyes. They serve as precursors that undergo specific chemical reactions to create the final dye product. These intermediates are crucial for determining the colour, stability, and performance of the dye. Proper handling and formulation of dye intermediates are essential for achieving the desired dye characteristics and ensuring consistent quality in various applications. These intermediaries can be commonly used for production of various dyes. For e.g. H Acid can be used for production of Acid as well as Reactive dyes.
6. Reactive Dyes
Reactive dyes are a class of dyes that form a covalent bond with the fibers, typically cotton or other cellulose-based fabrics, during the dyeing process. This chemical reaction ensures that the dye becomes a permanent part of the fabric, resulting in vibrant colours with excellent wash and light fastness. Because of their strong bonding and durability, reactive dyes are widely used in textile industries to produce long-lasting and high-quality colored fabrics.
