Description

Disperse Blue 270 is a high-performance synthetic dye belonging to the anthraquinone class of disperse dyes. It is valued for its excellent color fastness, brilliant blue shade, and strong affinity for synthetic fibers, making it a critical component in demanding coloration processes. This product is essential for manufacturers in the textile and polymer industries seeking consistent, high-quality coloration for hydrophobic materials.

Application

• Primary dyeing of polyester (PET) fibers and fabrics.
• Coloration of polyamide (nylon) textiles.
• Dyeing of acetate and triacetate fibers.
• Mass coloration (dope dyeing) of synthetic polymers during the melt-spinning process.
• Used in the production of high-visibility and automotive textiles requiring excellent light and wash fastness.
• Formulation of disperse dye mixtures and specialty colorants for technical applications.
