Dyeing is a process of coloring fabrics, yarns, or fibers using various dyeing techniques and natural or synthetic dyes. It is one of the oldest and most important processes in the textile industry, dating back thousands of years. Dyeing can be done at different stages of textile production, from raw fibers to finished garments, and can involve different methods such as vat dyeing, reactive dyeing, direct dyeing, and many others. The choice of dye and dyeing technique depends on the type of fabric, the desired color, and the intended end-use of the textile product.
