Description

Direct Blue 267 is a synthetic, high-strength disazo direct dye belonging to the benzidine derivative class. It is valued for its excellent substantivity to cellulosic fibers, providing deep, vibrant blue shades with good wash and light fastness properties. This dye is essential for manufacturers in the textile industry requiring consistent, high-quality coloration for cotton, viscose, and other regenerated fibers.

Application

• Primary dyeing and printing of cotton fabrics and yarns.
• Coloration of viscose rayon and other regenerated cellulose materials.
• Used in the production of paper for specialty applications requiring color.
• Dyeing of leather to achieve uniform blue hues.
• Potential use as a colorant for wood staining and other non-textile substrates.
• Formulation of ink for specific industrial marking applications.
