Dyeing agents are substances used to impart color to materials such as fabrics, paper, and even food. They work by chemically bonding with the material, allowing the color to remain vibrant and durable. Common types of dyeing agents include natural dyes, derived from plants and minerals, and synthetic dyes, which are chemically manufactured. These agents can be applied through various methods, including immersion, spraying, or printing. The choice of dyeing agent often depends on the desired color, the type of material, and the intended use. Proper application ensures that the color is evenly distributed and long-lasting.
