Direct Dyes

Direct dye, as the name suggests, applied directly to the substrate in either neutral or alkaline bath. This is majorly used to dye fabric, like linen, nylon, leather, viscose, cotton, silk, silk jute, wool and rayon. The fabric once dyed in dyebath at or near boiling point, requires after-treatments (for instance cationic dye fix), in order to enhance dye's washfastness. Paper can also be subjected to direct dyeing. These salts of complex sulfonic acids have anionic as ionic nature and are soluble in water. Electrolyte or sodium carbonate is added in the dyebath for dyeing application. For the level dyeing, factors that need to be considered are dyeing temperature, rate of heating, electrolyte concentration, time, dye solubility and leveling agent. This dye is attached to fibers with hydrogen bonding.
