Description

C.I. Reactive Yellow 22 is a high-performance, water-soluble reactive dye belonging to the vinyl sulfone class, known for its bright and vibrant yellow hue. Its primary value lies in its ability to form strong covalent bonds with cellulosic fibers, resulting in excellent wash and light fastness properties. This dye is essential for manufacturers in the textile industry seeking reliable and consistent coloration for cotton, viscose, and other natural fabrics.

Application

• Exhaust Dyeing of Cellulosic Fibers: Primary application for dyeing cotton, rayon, linen, and hemp in batch processes, offering good leveling and reproducibility.
• Continuous Dyeing (Pad-Batch/Steam): Used in high-throughput pad-batch and pad-steam processes for uniform coloration of woven and knitted fabrics.
• Yarn Dyeing: Suitable for dyeing cellulosic yarns in package, beam, or hank dyeing machines for subsequent weaving or knitting.
• Union Dyeing: Can be applied in combination with other dye classes for dyeing blended fabrics containing cellulose.
• Printing Pastes: Formulated into printing pastes for direct or discharge printing on cellulosic textiles.
• Technical Textiles: Used for coloring industrial textiles where good fastness properties are required.
