Description

Disperse Blue 26 is a synthetic anthraquinone derivative dye widely recognized for its vibrant blue hue and excellent fastness properties. This product is essential for achieving deep, wash-resistant coloration on hydrophobic synthetic fibers, particularly polyester and acetate. It is a critical component for textile manufacturers, dye houses, and industrial colorant producers seeking reliable and consistent performance in high-temperature dyeing processes.

Application

• Textile Dyeing: Primary application for dyeing polyester, polyester blends, and acetate fibers, especially via high-temperature pressure dyeing and thermosol processes.
• Plastics Coloring: Used as a colorant for mass coloration of various plastics, including polystyrene, polycarbonate, and acrylics, where good dispersion and heat stability are required.
• Ink Manufacturing: Employed in the formulation of specialty inks for non-porous substrates, such as those used in transfer printing.
• Automotive Interiors: Suitable for coloring synthetic fabrics and plastics used in vehicle upholstery and trim due to its light and wash fastness.
• Synthetic Fiber Masterbatch: A key ingredient in color concentrates (masterbatches) for synthetic fiber production, ensuring uniform color distribution.
• Research & Development: Serves as a standard or reference material in analytical chemistry and dye research laboratories.
