Dyeing is the process of adding color to materials, such as fabrics, yarns, or even food. This is typically done using a liquid solution that contains colorants, known as dyes. The dye penetrates the material, resulting in a permanent change in color. Different methods of dyeing can be used, including immersion, where the material is soaked in the dye, or surface application, where the dye is applied directly. There are various types of dyes, including natural dyes derived from plants and synthetic dyes created in laboratories. The choice of dye often depends on the material being colored and the desired outcome. Textiles, colorants, and natural dyes are all important concepts in the dyeing process.
