Acid Yellow 204

High-Performance Acid Yellow 204 Dye from Ahmedabad, Gujarat

Acid Yellow 204 is a premium-grade anionic dye engineered for exceptional color yield and consistent performance across textile and industrial applications. Formulated to meet rigorous quality standards, this water-soluble synthetic dye is specifically designed for coloring protein fibers and synthetic polymers such as wool, silk, nylon, and modified acrylic fibers from neutral to acid dye baths. Classified under milling, super-milling, and fast acid dye categories, it delivers excellent colorfastness, uniform coverage, and vibrant yellow shades for commercial dyeing facilities and specialized studio dyers alike.

Acid Yellow 204 operates efficiently in acidic processing environments, requiring the addition of mild or strong acids—such as acetic acid, vinegar, or sulphuric acid—to fix the dye molecules onto the target substrate securely. Its molecular structure (C28H20N2Na2O8S2) provides optimal solubility and superior chemical stability during elevated temperature processing. Manufactured with high precision in Ahmedabad, Gujarat, this dye provides dependable batch-to-batch consistency for industrial textile processors, yarn producers, and specialized dye houses across global markets.

Key Features and Benefits

• Superior Solubility: Water-soluble anionic formulation ensures rapid dissolve rates and uniform liquor distribution during bath preparation.

• Broad Substrate Compatibility: Ideal for dyeing protein-based natural fibers including wool and silk, as well as synthetic fibers such as nylon and modified acrylics.

• Versatile Dye Bath Range: Operates effectively across varying bath conditions from neutral to acidic pH levels.

• High Fastness Ratings: Offers dependable fastness properties under milling acid, super-milling, and fast acid classification requirements.

• Flexible Processing Scale: Perfectly suited for large-scale industrial commercial operations as well as craft studio dyeing applications.

Applications and Usage

Acid Yellow 204 is extensively utilized in textile wet-processing units for dyeing yarn, woven fabrics, and knitted materials. To achieve optimal shade intensity and fastness, prepare the dye bath with water and adjust the pH using appropriate acidic agents such as acetic acid or sulphuric acid based on the specific fiber type and shade depth required.
