Description

C.I. Disperse Blue 171 is a high-performance, anthraquinone-based disperse dye widely used in synthetic fiber coloration. This product is valued for its excellent color fastness properties, including good lightfastness and wash fastness, which are critical for durable textile applications. It is primarily needed by manufacturers in the textile and polymer industries for dyeing polyester, acetate, and nylon fibers.

Application

• Primary dyeing of polyester fibers and fabrics.
• Dyeing of cellulose acetate and triacetate fibers.
• Coloration of nylon and other synthetic polyamide materials.
• Mass coloration of plastics and synthetic polymers.
• Used in the production of high-fastness automotive textiles.
• Application in sportswear and outdoor apparel requiring durable colors.
• Potential use in ink formulations for specialized printing.
