Textile dye is a substance used to add color to fabrics and fibers. It can be derived from natural sources, such as plants and minerals, or created synthetically in laboratories. Dyes work by chemically bonding with the material, ensuring that the color remains vibrant and durable through washing and wear. There are various types of textile dyes, including reactive dyes, acid dyes, and disperse dyes, each suited for different materials and applications. The dyeing process can involve techniques like immersion, spraying, or printing, allowing for a wide range of colors and patterns on textiles.
