Dyes are colored substances that chemically bind to fibers, unlike pigments which remain on the surface. The preparation of dyes involves understanding their chemical nature, including chromophores and auxochromes, and can be achieved through natural extraction or synthetic methods. The dyeing process varies based on the fiber type and includes techniques such as direct dyeing, mordant dyeing, and vat dyeing, with applications in textiles, food, and cosmetics.
