happoväriaineita
Happoväriaineita, known in English as acid dyes, are a class of anionic dyes that are applied to textiles from an acidic dyebath. These dyes are typically water-soluble and are characterized by the presence of acidic functional groups, such as sulfonic acid groups. Their affinity is primarily for fibers that contain basic functional groups, making them particularly effective for dyeing protein fibers like wool and silk, as well as polyamide (nylon) fibers.
The dyeing process for acid dyes involves a chemical reaction between the acidic dye molecule and the
Acid dyes are available in a wide spectrum of colors and exhibit good lightfastness and washfastness on
