Description

Disperse Blue 72 is a high-performance anthraquinone-based disperse dye, valued for its excellent color fastness and thermal stability. It is a critical component for achieving deep, vibrant blue shades with superior wash and light resistance in synthetic textiles. This product is essential for manufacturers in the polyester, acetate, and nylon dyeing industries seeking consistent, high-quality coloration for apparel, home furnishings, and automotive textiles.

Application

• Primary dyeing of polyester fibers and fabrics for apparel and sportswear.
• Coloration of acetate and triacetate materials used in linings and luxury garments.
• Dyeing of nylon and polyamide fibers for carpets, upholstery, and technical textiles.
• Used in high-temperature dyeing processes (e.g., carrier or pressure dyeing) due to its stability.
• Application in the mass coloration of synthetic polymers during the spinning process.
• Suitable for printing inks formulated for synthetic fabrics.
