Fabric dyes are substances used to add color to textiles and materials. They can be derived from natural sources, like plants and minerals, or created synthetically in laboratories. Different types of dyes are available, including reactive dyes, acid dyes, and disperse dyes, each suited for specific fabrics and applications. The dyeing process involves applying the dye to the fabric, often using heat or chemicals to fix the color. This can be done through various methods, such as immersion dyeing, tie-dyeing, or screen printing. Proper dyeing techniques ensure vibrant colors and long-lasting results on the fabric.
