When employed at shorter depths, this reactive black dye produces a superb jet black colour. It possesses strong post-mercerization fastness and great salt solubility. This dye has the ability to be easily washed off. Both its visual distinction and longevity increased significantly. Its considerable advantage over both illegal and cellulose colours is due to this characteristic. Its wet speed was made possible by an effective and simple colouring procedure. A new class of cellulose fibre products, like Lyocell fibers, can be dyed using this reactive black dye.
