Direct Black 80 is a high-strength anionic direct dye mainly used for dyeing cotton and other cellulosic fibers. It produces a deep black to greenish-black shade with good substantivity and uniform dyeing properties. This dye is applied directly to cotton without the need for a mordant, making it suitable for exhaust and continuous dyeing processes.
