Acid dyes are a specialized type of dye used to color natural and synthetic fibers. They require an acidic environment for effective dyeing and can bond with the fibers through ionic and hydrogen bonding interactions. Acid dyes are soluble in water and offer a wide range of vibrant colors. They exhibit good Colorfastness and are commonly used on protein-based fibers like raw leather, wool and silk. Acid dyes are essential for adding long-lasting and intense color.


Characteristics of acid dyes

Acid Dyes are water-soluble anionic dyes applied to fibers such as silk, wool, leather from neutral to acid dye baths. Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups. Acid Dyes of Sardar Chemical include a wide range with certifications of Azo free. Key Features of Acid Dyes are:

What are the properties of acid dyes?

Due to the sodium salt’s large anion in aqueous solutions, these are usually sold as sodium salts. Below are the properties of acid dyes:

Using acid dyes involves a specific acid dyeing process to ensure effective and vibrant coloration. Here are the steps to follow when using acid dyes:

Preparing the dye bath

Preparing the fabric or fiber

Dyeing process

Rinsing and aftercare
