Disperse Blue 359 is an anthraquinone disperse dye with extremely low water solubility. It relies on dispersing agents to form a stable aqueous dispersion system, making it highly compatible with mainstream high-temperature dyeing processes for polyester fibers. This dye boasts high color saturation, a bright and luminous shade, and excellent transfer efficiency.
