Description
C.I. Reactive Brown 17 is a high-performance, bifunctional reactive dye designed for covalent bonding with cellulose fibers. This product matters for its excellent wash and light fastness properties, providing durable and vibrant brown shades in demanding textile applications. It is primarily needed by textile manufacturers for dyeing and printing cotton, viscose, and other cellulosic fabrics, ensuring consistent color yield and process reliability.
Application
- Exhaust dyeing of cotton yarn and knitted fabrics.
- Continuous pad-dyeing and pad-steam processes for woven cellulosic materials.
- Textile printing applications on natural fiber substrates.
- Garment dyeing for consistent and level shades.
- Dyeing of viscose rayon and other regenerated cellulose fibers.
- Potential use in the coloration of leather where reactive dyes are specified.
