Browniline is widely used as a dye in the textile industry, particularly for coloring wool, silk, and nylon fabrics. It provides a consistent, medium brown shade with good color fastness when mordanted properly. The dye is also applied in the leather industry to color finished leather goods, offering an attractive earth tone suitable for footwear and upholstery. In addition, Browniline finds use in paper staining and in some specialty inks where a natural brown hue is desired. Its compatibility with various mordants allows for shade variation, enhancing its utility in industrial dyeing processes.
