[0002] Dyes refer to a class of organic compounds that can give other substances a bright and firm color. Since the pigments currently used are all artificially synthesized, they are also called synthetic dyes. Synthetic dyes are made in a reactor. During the chemical reaction, some precipitates will be produced. In order to ensure the quality of the dye and ensure that the dye is more uniform during the dyeing process, these precipitates need to be removed.
