Description

C.I. Reactive Red 155 is a high-performance, bifunctional reactive dye belonging to the vinyl sulfone and monochlorotriazine chemical class. This compound is engineered for exceptional color yield and fixation properties, making it a critical component for achieving vibrant, wash-fast red shades on cellulosic fibers. It is primarily required by textile manufacturers and dye houses engaged in the production of cotton, viscose, and other natural fiber fabrics. The product, identified by CAS NO 88385-26-6, is valued for its reliability in exhaust, pad-batch, and continuous dyeing processes.

Application

• Exhaust dyeing of cotton and viscose yarns and fabrics.
• Pad-batch and continuous dyeing processes for woven and knitted cellulosic textiles.
• Production of home textiles, including bed linens, towels, and curtains, requiring high colorfastness.
• Dyeing of garments and fashion apparel where bright red shades are essential.
• Used in combination with other reactive dyes to build a wide spectrum of colors.
• Application in the dyeing of hemp and other natural cellulosic fibers.
