Reactive Yellow 3 is widely used in the textile industry for dyeing cellulosic fibers such as cotton, rayon, and linen. It forms a strong covalent bond with the fiber under alkaline conditions, resulting in excellent color fastness to washing and light exposure. This dye is particularly valued in batch and continuous dyeing processes where bright yellow shades are required. It is also applied in printing fabrics using screen printing techniques due to its good solubility and reactivity. Additionally, Reactive Yellow 3 is used in the dyeing of blended fabrics when combined with other reactive dyes to achieve a range of shades. Its application extends to paper printing and leather dyeing in some industrial processes.
