Disperse dyes are a type of dye specifically designed for coloring synthetic fibers, such as polyester and nylon. Unlike other dyes, they are not soluble in water; instead, they are finely ground and dispersed in a liquid medium. This allows them to penetrate the fibers during the dyeing process, resulting in vibrant and long-lasting colors. These dyes are commonly used in the textile industry for dyeing fabrics and garments. They can be applied using various methods, including high-temperature dyeing and printing. Disperse dyes are known for their excellent lightfastness and washfastness, making them ideal for items that require durability.
