Reactive Yellow HeR

Reactive Yellow HeR is a high-exhaust, mono-functional reactive dye used predominantly in the textile industry for dyeing and printing cellulosic fibers like cotton, viscose, and their blends. This dye contains a reactive group that forms a covalent bond with hydroxyl groups in cellulose under alkaline conditions, ensuring excellent wash fastness and color retention. Reactive Yellow HeR is valued for its bright yellow hue, good solubility, and compatibility with continuous, semi-continuous, and batch dyeing processes.
