Description

Disperse Red 167:1 is a high-performance, monoazo-based disperse dye. It is valued for its excellent color fastness properties, particularly its lightfastness and sublimation fastness, making it a critical component for demanding textile applications. This dye is primarily used by manufacturers in the synthetic fiber industry seeking vibrant and durable red colorations.

Application

• Primary dyeing of polyester (PES) fibers and fabrics.
• Dyeing of polyester blends, including polyester/cotton and polyester/wool.
• Textile printing applications for synthetic materials.
• Imparting color to polyamide (nylon) fibers.
• Used in the coloration of acetate and triacetate fibers.
• Employed in high-temperature dyeing processes (HT dyeing) for optimal exhaustion and fixation.
• Suitable for applications requiring excellent wash and perspiration fastness.
