Disperse dyeing is a method used primarily for dyeing synthetic fibers, such as polyester and nylon. This technique involves using disperse dyes, which are water-insoluble and can be dispersed in water as fine particles. The dyeing process typically requires high temperatures to allow the dye to penetrate the fiber, resulting in vibrant and long-lasting colors. During the dyeing process, the fabric is immersed in a dye bath at elevated temperatures, often around 130°C (266°F). The heat helps the dye particles to migrate into the fiber, where they bond chemically. This method is popular in the textile industry for producing colorful and durable fabrics.
