Leather

Acid dyes are often used for dyeing leather products such as shoes, bags and interior decoration.
Basic dyes are known for their bright and strong tones and are mainly used for dyeing leather clothing and accessories. Direct dyes can be directly dyed on fibers after being dissolved in water. They have good color fastness and are suitable for dyeing light and dark leathers.

Reactive dyes can form covalent bonds with leather fibers, thus having excellent wash and light fastness. They are often used for dyeing leather products with high color fastness requirements, such as automotive interior leather, high-end furniture leather, etc.
Reducing dyes have strong anti-fading properties and are often used for dyeing leather products that require high durability.
The use of leather dyes is more to meet specific functional needs or artistic effects.
