Description

C.I. Reactive Yellow 95 is a high-performance, water-soluble reactive dye belonging to the vinyl sulfone class, known for its bright yellow hue and excellent fastness properties. Its primary value lies in its ability to form a strong covalent bond with cellulosic fibers, ensuring brilliant, wash-fast, and lightfast coloration. This dye is essential for textile manufacturers and dye houses specializing in the coloration of cotton, viscose, and other natural fibers, as well as for applications requiring high wet fastness. The compound is identified by CAS No. 71838-98-7.

Application

• Exhaust dyeing of cotton and viscose yarns and fabrics.
• Continuous pad-batch and pad-steam dyeing processes for woven and knitted cellulosic textiles.
• Used in combination with other reactive dyes to produce a wide range of green and olive shades.
• Ideal for applications demanding high levels of wash fastness and lightfastness.
• Suitable for the dyeing of hemp, linen, and other natural cellulosic materials.
• Employed in the textile printing industry for creating sharp, durable prints.
