1. Textile fiber dyeing (core application)

Sulphur black BR is mainly used for dyeing cotton textiles, and is also widely used for dyeing hemp, viscose fibers, and wool/cotton blended fabrics. Its dyeing process has a wide range of applications, including immersion dyeing, roll dyeing, and pad dyeing, with good dye uptake and uniformity. When dyeing, it is necessary to use reducing agents such as sodium sulfide to reduce insoluble dyes into soluble chromophores, which are adsorbed by fibers and then oxidized to develop color, and fixed on fibers.

2. Leather dyeing

Water soluble sulphur black can be used for dyeing tanned leather, providing uniform black color for leather products.

3. Paper dyeing

Sulphur black is also used in the field of paper dyeing to meet the color requirements of specific paper products.

4. Coloring of viscose fiber solution

In the production process of adhesive fibers, sulfur black can be used in the coloring process of the original solution to achieve uniform color of the fibers before molding.
