Description

Disperse Yellow 163 is a high-performance synthetic organic dye belonging to the disperse dye class, widely recognized for its vibrant yellow hue and excellent fastness properties. It is engineered to provide superior color strength and dispersion stability, which are critical for achieving uniform and durable coloration on synthetic fibers. This product is essential for manufacturers in the textile and polymer industries seeking reliable and consistent yellow pigments for their dyeing and printing processes. Its quality and performance make it a key component for producing colorfast synthetic fabrics and specialty plastics.

Application

• Primary dyeing and printing of polyester (PET) fibers and fabrics.
• Coloration of polyamide (nylon) textiles.
• Mass pigmentation and spin-dyeing of synthetic polymers and plastics.
• Manufacturing of transfer papers for sublimation printing.
• Production of colored acetate and triacetate fibers.
• Industrial applications requiring lightfast and washfast yellow pigments.
