When discussing fabric dyeing, the primary focus is on colorants. While some colorants can dye independently, most require auxiliary compounds called mordants to bond with the fabric and stabilize the color. Chintz, cotton fabrics known for their intricate patterns, use colorless metallic salts like alum or iron along with botanical dyes. These fabrics became popular in Mallorca in the 18th century, with varieties from France and Barcelona each adding to the rich tapestry of textile history. This dry dyeing technique conserves water and allows for vibrant, multicolored effects in a single dye bath.
