Cas no 1325-37-7 (Direct Yellow 11)
Direct Yellow 11 is an azo dye commonly used in textile, paper, and leather industries for its bright yellow hue and good lightfastness. It exhibits strong affinity for cellulose fibers, ensuring uniform dyeing with high color yield. The dye is soluble in water, facilitating easy application in aqueous dyeing processes. Its molecular structure provides moderate resistance to washing and perspiration, making it suitable for applications requiring durability. Direct Yellow 11 is compatible with standard dyeing techniques and can be used in combination with other direct dyes to achieve a range of shades. Its cost-effectiveness and consistent performance make it a practical choice for industrial use.
