Classification of Dyes

Dyes can be classified in several ways, each class has a very unique chemistry, structure and particular way of bonding. Some dyes can react chemically with the substrates forming strong bonds in the process, and others can be held by physical forces. Some of the prominent ways of classification are given below
  • Natural / Synthetic
  • Organic / Inorganic
  • By area and method of application
  • Chemical classification - Based on the nature of their respective chromophores.
  • By nature of the Electronic Excitation (i.e., energy transfer colorants, absorption colorants and fluorescent colorants).
  • According to the dyeing methods
    • Anionic (for Protein fibre)
    • Direct (Cellulose)
    • Disperse (Polyamide fibres)
