Description

Dianix Blue Fg-Se CAS NO 86438-37-1 is a high-performance, anthraquinone-based disperse dye specifically engineered for demanding textile applications. It is valued for its excellent color fastness properties, including superior wash, light, and sublimation fastness, ensuring vibrant and durable coloration. This product is essential for manufacturers of synthetic fibers, particularly polyester and its blends, seeking reliable and consistent dyeing results for apparel, home textiles, and technical fabrics.

Application

• Primary dyeing of polyester fibers and yarns for apparel and sportswear.
• Dyeing of polyester/cellulose (e.g., cotton) blend fabrics.
• Coloration of polyester-based home textiles, such as curtains and upholstery.
• Use in high-temperature dyeing processes (e.g., carrier-free dyeing at 130°C).
• Applications requiring excellent sublimation fastness for fabrics subjected to heat during finishing or ironing.
• Production of automotive textiles where color stability is critical.
• Dyeing of technical textiles and industrial fabrics.
