Whether it’s fashion fabrics, industrial yarns, or high-end leather goods, acid dyes are essential for delivering consistent, vibrant colour in environments that demand chemical compatibility and long-lasting performance.
What Are Acid Dyes?
Acid dyes are water-soluble, anionic (negatively charged) dyes that are applied to fibers in an acidic environment. They are primarily used for dyeing:
• Protein fibers like wool and silk
• Polyamide fibers such as nylon
• Leather and certain modified acrylics
These dyes form ionic bonds with the positively charged amine groups in the fibers, resulting in excellent wash fastness and colour depth.
How Dycron Manufactures Acid Dyes
Dycron’s acid dyes are produced using advanced synthesis techniques that ensure purity, consistency, and compliance with industry-specific performance parameters. Our manufacturing process includes:
1. Dye Synthesis
We begin by reacting aromatic compounds with sulfonic acids and other agents under controlled pH and temperature. This yields dye molecules with strong chromophore structures and high solubility in water.
2. Filtration and Purification
Crude dyes are filtered to remove impurities and are washed thoroughly to achieve high levels of purity. This ensures stable shades and avoids staining or uneven dyeing during application.
3. Spray Drying and Powdering
The purified dye solution is dried into fine powder using high-efficiency spray dryers. Particle size is controlled to ensure smooth dispersion in aqueous systems and precise shade development.
4. Shade Standardization and Testing
Each batch is color-matched and tested against international shade cards (CI Numbers) to ensure standardization. We also run tests for:
• pH level
• Solubility
• Light, rub, and wash fastness
• Colour yield and levelling properties
Types of Acid Dyes We Offer
Dycron manufactures a wide range of acid dyes, including:
• Leveling Acid Dyes: For even dyeing on wool and silk
