description Product Description

Direct Black 38 is widely used in the textile industry as a dye for coloring cotton, rayon, and other cellulose-based fibers. It provides a deep black shade and is valued for its strong affinity to these materials, ensuring good color fastness. Additionally, it is employed in paper dyeing to achieve consistent and durable black tones. In some cases, it is also used in leather dyeing processes to produce dark, uniform finishes. Its effectiveness in binding to natural fibers makes it a popular choice in industries requiring long-lasting and intense black coloration.
