Direct Dyes is a class of dyestuffs that are applied directly to the substrate in a neutral or alkaline bath. They produce full shades on cotton and linen without mordanting and can also be applied to rayon, silk, and wool. Direct dyes give bright shades but exhibit average wash fastness.
🔸 These direct dyes are non-benzedene dyestuffs.
🔸 Suitable for dyeing cotton and viscose in the form of fabric,
yarn as well as loose cotton.
🔸 They are also used for dyeing of wool, pure silk & leather
in certain cases.
