ingrain dye, any of a group of azo dyes that are produced within the fibre from chemical precursors and attach themselves by an irreversible chemical change, so that the dyeing shows improved fastness. Usually, the bonding of the dye molecules occurs through the hydroxyl or amino groups of the fibre (cotton, silk, or wool).
