Widely used in the textile industry for dyeing acrylic fibers, Astrazon Red 6B provides bright, intense red shades with good lightfastness and wash fastness. It is particularly effective in dyeing synthetic fabrics used in apparel, home textiles, and industrial materials. Commonly applied through exhaust or continuous dyeing methods, it offers excellent leveling properties, ensuring uniform color distribution. Also utilized in the dyeing of polyamide and modified polyester fibers when specific red tones are required. Its cationic nature allows strong affinity to negatively charged fiber sites, enhancing color uptake and reducing dye waste. Additionally, it finds use in paper printing and as a colorant in some specialty inks.
