Acid Black ATT Application
Acid Black ATT is primarily used for dyeing fibers (such as wool, silk, etc.), leather, paper, and even tree bark. As it is an acid dye, it requires an acidic dyeing process during application.
Acid dyes on leather
1. Vivid Color: Acid dyes can produce bright and vibrant colors, offering a wide range of color choices, from bright to deep shades.
2. Suitable for Natural Fibers: Acid dyes are particularly suitable for dyeing natural fibers like leather and silk. They chemically react with the amino acids in these fibers, resulting in long-lasting dyeing effects.
3. Good Affinity: Acid dyes exhibit good affinity for leather, resulting in even dyeing and avoiding color deviation.
4. Lightfastness: Dyeing leather with acid dyes typically results in good lightfastness, meaning the color is resistant to fading or discoloration, even when exposed to sunlight.
5. Water Resistance: Acid dyes generally possess a certain degree of water resistance, making the dyed leather more resistant to water.
