Reactive Brown 9 is a dichlorotriazine (DCT) reactive dye, commonly known as a “hot brand” dye. It is designed for optimal performance when dyeing cellulosic fibres at high temperatures (approx. 80°C), where it achieves a high degree of fixation. It produces a deep, reddish-brown shade and is valued for its robust performance in high-temperature exhaust dyeing and printing processes that utilize steam fixation.
