Indigo Dye

Nature — What Is Indigo Dye?

Indigo Dye is a deep blue dye traditionally used for denim and heritage textiles.

Unlike many dyes, indigo sits primarily on the fiber surface, creating its signature fading and aging characteristics.

Scientific Structure (Explained Clearly)

Indigo is a vat dye that becomes soluble in a reduced alkaline solution, allowing it to penetrate fibers. Upon exposure to oxygen, it oxidizes and returns to its insoluble blue form, bonding to the fiber surface.

  • Vat dye chemistry
  • Oxidation-based color development
  • Surface-level fiber bonding
  • Layered dyeing process for depth
