Description

C.I. Disperse Yellow 67 is a synthetic organic dye belonging to the disperse dye class, widely recognized for its bright yellow hue. It is valued for its excellent color fastness properties, particularly its lightfastness and sublimation fastness, which are critical for demanding textile applications. This dye is primarily needed by manufacturers in the polyester and acetate fiber industries for dyeing and printing, as well as by producers of specialty plastics and inks.

Application

• Dyeing of polyester fibers and fabrics, including textured yarns and microfibers.
• Printing on polyester textiles for apparel, home furnishings, and automotive interiors.
• Coloration of secondary acetate and triacetate fibers.
• Mass coloration (spin dyeing) of synthetic polymers during fiber production.
• Dyeing of polyester/cellulose or polyester/wool blended fabrics.
• Manufacture of colored masterbatches for engineering plastics.
• Production of specialty inks for transfer printing and other industrial marking applications.
