Description

Disperse Blue 341 is a high-performance synthetic dye belonging to the disperse dye class, specifically engineered for hydrophobic fibers. This product matters for its excellent color fastness, thermal stability, and bright blue shade, which are critical for demanding textile applications. It is primarily needed by manufacturers in the polyester, acetate, and nylon dyeing industries, as well as for specialty applications in plastics coloration.

Application

• Primary dyeing of polyester fibers and fabrics (textile, apparel, home furnishings).
• Dyeing of acetate and triacetate materials.
• Coloration of nylon and polyamide fibers.
• Mass coloration (spin dyeing) of synthetic polymers and plastics.
• Printing inks for synthetic textiles.
• Manufacture of dye concentrates and masterbatches.
