Description

Reactive Yellow 167 is a high-performance, water-soluble azo-based reactive dye designed for demanding coloration processes. Its primary value lies in its excellent fixation properties, providing vibrant yellow shades with superior wash and light fastness on cellulosic fibers. This dye is essential for textile manufacturers and dye houses seeking consistent, high-quality coloration for cotton, viscose, and other natural fibers. Its reliable performance makes it a key component in the production of durable and colorfast textiles for apparel and home furnishings.

Application

• Exhaust dyeing of cotton and viscose yarns and fabrics.
• Continuous pad-dry and pad-steam dyeing processes for woven textiles.
• Coloration of cellulosic fibers in knitwear and garment dyeing applications.
• Used in combination with other reactive dyes to achieve a broad spectrum of shades.
• Suitable for dyeing in industrial jet, overflow, and winch dyeing machines.
• Application in the production of home textiles like bed linens and towels requiring high colorfastness.
