Widely used in the textile industry for dyeing synthetic fibers such as polyester, Disperse Red 1 provides a bright red color with good lightfastness and even dyeing properties. It is especially effective in high-temperature dyeing processes and carrier dyeing methods. Commonly applied in the coloring of fabrics for apparel, home textiles, and industrial materials. Also used in some ink formulations and plastic coloration where a stable red hue is required. Due to its disperse nature, it remains insoluble in water, which makes it suitable for dyeing hydrophobic materials.
