About 34 Red Acid Dyes

34 red acid dyes are a group of dyes that are used to colour textile fibres and other materials. These colours were formerly made from coal tar and other materials. They have strong colour fastness qualities and are water soluble. Wool, silk, nylon, and other protein-based materials can be dyed with our offered pigments. In addition to this, the said products are also utilized for dying fabrics that are ideal for making clothes, carpeting, and furniture. Tussah and wool products can be dyed, while casein plastic, paper, and leather can also be dyed. 34 red acid dyes are frequently used to colour synthetic polyamide (nylon), acrylic fibres, mixes of these fibres, and natural protein (wool and silk).

Outstanding Compatibility and Performance

Acid Red 34 demonstrates remarkable compatibility with most acids and mordants, ensuring uniform color uptake for textile, leather, and paper applications. Its high strength (120% standard) and purity (99%) result in vibrant, durable shades that resist light, washing, and rubbing, making it ideal for demanding environments.

Safe and Convenient Handling

This dye is non-hazardous, non-poisonous, and odorless, making it safe for handling and suitable for industrial-scale processing. The product should be stored in a cool, dry place, away from direct sunlight, to maintain stability and performance over its two-year shelf life. Packaged for ease in 25 kg HDPE bags or fiber drums.

Diverse Industrial Applications

Acid Red 34 serves a versatile role across textile dyeing, leather finishing, and paper coloring industries. Its bright hue and stable performance make it a top choice for nylon, wool, silk, and leather, ensuring consistently excellent results with every batch.
