Description

Disperse Yellow 126 is a high-performance synthetic organic dye belonging to the disperse dye class, widely recognized for its bright and durable yellow coloration. Its primary value lies in its excellent sublimation fastness and wash fastness, making it ideal for demanding textile applications where color retention is critical. This product is essential for manufacturers in the polyester and acetate fiber industries, as well as for specialty applications in plastics and inks.

Application

• Primary dyeing and printing of polyester fibers and fabrics.
• Coloration of acetate and triacetate textiles.
• Mass coloration (dope dyeing) of synthetic polymers including certain plastics.
• Manufacture of transfer printing papers for the textile industry.
• Production of inks for specialized printing applications.
• Used in blends of polyester with other fibers like cotton or wool.

Quality Control

Our Disperse Yellow 126 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. The product is tested against key parameters including color strength, shade, particle size distribution, and dispersion stability. A Certificate of Analysis (COA) detailing purity, physical properties, and application performance is provided with every shipment to guarantee it meets your specific technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed when not in use to prevent moisture absorption and degradation.
