SULPHUR BLACK

SulphSulur Black
Product Description
Sulphur Black is a synthetic sulfur-based dye renowned for its deep black color and excellent fastness properties, especially on cellulose fibers like cotton. It is widely used in textile dyeing due to its cost-effectiveness and ability to produce dark, durable black shades. Sulphur Black is insoluble in water but applied through a reduction process that allows it to penetrate fibers and form insoluble pigments within the fabric, offering excellent wash and light fastness.

Uses
Primary Uses
Textile Chemicals

• Extensively used for dyeing cotton, viscose, and other cellulose fibers to produce rich, deep black colors. 
• Applied in vat and sulfur dyeing processes providing durable color with good wash and light fastness. 
• Used in textile printing for creating dark black patterns and designs. 

Leather Processing Grade

• Occasionally utilized in leather dyeing processes to achieve stable black coloration with good fastness properties.
