Description

Disperse Orange 44 is a synthetic organic dye belonging to the disperse azo dye class. This high-performance colorant is valued for its ability to impart bright, durable orange shades to synthetic fibers with excellent fastness properties. It is primarily used in the textile industry for dyeing and printing hydrophobic materials like polyester, acetate, and nylon. Our supply of Disperse Orange 44 CAS NO 4058-30-4 ensures consistent quality and reliable performance for demanding industrial applications.

Application

• Primary dyeing of polyester fibers and fabrics.
• Printing applications on polyester and polyester-blend textiles.
• Dyeing of secondary synthetic fibers, including acetate and triacetate.
• Coloration of nylon and polyamide-based materials.
• Used in the production of colored masterbatches for plastics.
• Potential applications in the research and development of new polymeric colorants.
