Skyacido® Acid Orange GSN
Acid dyes are a significant class of synthetic dyes characterized by their acidic functional groups, such as sulfonic and carboxylic groups, which enable them to form anions in water. These dyes are primarily used to color protein fibers, like wool and silk, as well as polyamide fibers such as nylon. The dye molecules bind to the cationic groups in these fibers through electrostatic interactions, facilitating the dyeing process.
The dyeing process with acid dyes typically occurs under acidic conditions to ensure a strong bond between the dye molecules and the fibers. Fabrics dyed with acid dyes exhibit vibrant colors, a comprehensive range of shades, and good levelness and fastness properties. Due to the diverse structures of acid dyes, their molecular configurations can be adjusted to achieve different colors and performance characteristics, catering to various textile dyeing needs.
Beyond textiles, acid dyes are also widely used in leather, paper, food, and cosmetic industries
