Description

Acid Blue 335 is a synthetic acid dye belonging to the anthraquinone chemical class, valued for its bright and stable blue hue. It is a critical component for achieving high-quality, wash-fast coloration in polyamide fibers like nylon. This dye is essential for manufacturers in the textile and leather industries seeking consistent, vibrant color results for their products.

Application

• Primary dyeing of polyamide fibers, including nylon and wool.
• Printing applications on silk and polyamide textiles.
• Coloration of leather goods requiring acid dyes.
• Production of colored paper and specialty papers.
• As a colorant for inks and coatings where acid dye compatibility is required.
• Potential use in biological staining for microscopy (subject to specific grade purity).
