Description

Reactive Red 235 is a high-performance, bifunctional reactive dye designed for demanding textile coloration processes. Its primary value lies in providing excellent color yield, superior wash and light fastness, and high fixation rates on cellulosic fibers. This product is essential for textile manufacturers and dye houses seeking vibrant, durable red shades. The compound, identified by CAS No. 132579-39-6, is a key component in the production of high-quality cotton, viscose, and linen fabrics.

Application

• Exhaust dyeing of cotton yarns and fabrics.
• Continuous pad-batch and pad-steam dyeing of cellulosic textiles.
• Printing applications on cotton and viscose substrates.
• Dyeing of linen and other natural cellulosic fibers.
• Used in combination with other reactive dyes to achieve a broad color palette.
• Applicable in garment dyeing for consistent and level shades.
• Potential use in the coloration of paper pulp where reactive dyes are specified.
