Description

Disperse Blue 165:1 is a high-performance, anthraquinone-based disperse dye used for coloring synthetic fibers. It is valued for its excellent color fastness properties, including strong lightfastness and wash fastness, ensuring vibrant and durable coloration. This dye is primarily required by manufacturers in the textile industry for dyeing and printing polyester and its blends, as well as by producers of specialty inks and plastics.

Application

• Primary dyeing of polyester fibers and yarns.
• Printing applications on polyester fabrics.
• Coloration of polyester-cotton and other synthetic fiber blends.
• Manufacturing of color filters and other optical components.
• Production of specialty inks for non-textile applications.
• Coloring of certain engineering plastics.
