Description

Vat Brown 1, Solubilised is a specialized, pre-reduced form of the Vat Brown 1 dye, designed for ease of application and superior color yield. This product is essential for achieving deep, fast brown shades with excellent wash and light fastness properties on cellulosic fibers. It is primarily used by textile manufacturers and dye houses requiring consistent, high-performance coloration for cotton, viscose, and linen fabrics.

Application

• Dyeing of cotton yarns and fabrics for apparel and home textiles.
• Coloration of viscose and rayon materials to achieve rich brown hues.
• Printing applications on cellulosic substrates where a solubilised vat dye is preferred.
• Used in the production of workwear and outdoor fabrics demanding high colorfastness.
• Batch and continuous dyeing processes in industrial textile mills.
• As a key component in creating specific shade ranges and color blends.
