Description

C.I. Reactive Blue 108 is a high-performance, vinyl sulfone-based reactive dye belonging to the anthraquinone chemical class. It is valued for its excellent wash and light fastness properties, providing a brilliant and durable blue shade on cellulosic fibers. This product is essential for textile manufacturers and dye houses specializing in the coloration of cotton, viscose, and other natural fibers. Its consistent quality ensures reliable batch-to-batch reproducibility for industrial dyeing and printing processes.

Application

• Exhaust Dyeing of Cotton: Primary application for dyeing cotton yarns and fabrics in jet, overflow, and winch dyeing machines.
• Continuous Dyeing: Used in pad-batch and pad-steam processes for efficient, large-scale fabric production.
• Textile Printing: Formulated for printing inks to create sharp, vibrant blue patterns on cellulose-based textiles.
• Viscose and Rayon Dyeing: Effective for dyeing regenerated cellulose fibers, offering good exhaustion and fixation.
• Shade Building: A key component in trichromatic dyeing systems to achieve a wide range of green and navy shades.
• Industrial Laundry Marking: Used for durable identification and marking on cotton-based industrial linens.
