  Cationic dyes are a type of dye that carry a positive charge and are used to color materials that have a negative charge, such as acrylic fibers, nylon, and wool. These dyes are commonly used in the textile industry to color synthetic fibers, as well as in the paper industry to color paper and other pulp products. Cationic dyes are typically composed of organic molecules that contain quaternary ammonium groups, which give them a positive charge. This positive charge allows the dye molecules to be attracted to the negatively charged surface of the material being dyed. One of the benefits of using cationic dyes is that they are generally more resistant to fading than other types of dyes. This is because the positive charge on the dye molecules makes them more chemically stable and less likely to react with other substances that could cause them to break down or change color. Cationic dyes also have a high level of affinity for certain types of materials, which means they can be us...
