Description

Disperse Yellow 76 is a high-performance synthetic organic dye belonging to the disperse dye class, widely recognized for its vibrant yellow hue. Its primary value lies in its excellent sublimation fastness and strong affinity for synthetic hydrophobic fibers, ensuring color durability in demanding applications. This product is essential for manufacturers in the textile and plastics industries seeking reliable and consistent coloration. It is particularly valued for dyeing polyester and its blends, as well as for mass coloration of polymers.

Application

• Primary dyeing and printing of polyester (PET) fibers and fabrics.
• Coloration of polyester-cotton and other synthetic fiber blends.
• Mass coloration (spin dyeing) of polyester resins and plastics.
• Dyeing of acetate and triacetate fibers.
• Used in the production of transfer papers for sublimation printing.
• Potential use as a colorant for specific inks and coatings.
• Applied in laboratory research and development of new dye formulations.
