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.
