Widely used in the dyeing of polyester fibers, Disperse Yellow 64 provides bright yellow to yellowish-green shades with good lightfastness and wash fastness. It is especially effective in high-temperature dyeing processes and thermosol dyeing methods, making it suitable for synthetic fabrics used in apparel, home textiles, and industrial materials. The dye also finds application in inkjet printing on polyester substrates due to its solubility and color consistency. Its stability under heat and resistance to sublimation enhance performance in printing and dyeing operations.
