The raw materials used in polyester color masterbatch mainly have two major types: colorants and carriers. In accordance with the different colorants and carriers, some polyester color masterbills also need to add auxiliary. Usually, if the coloring agent is selected, the carrier is selected from the low melting polymer, generally need to be added to the appropriate auxiliary. If the colorant is selected from the polyester soluble dam, the vector is also a polyester itself, and it is generally not necessary to add any additives. The former situation and the general plastic masterbatch are similar, but all indicators are more demanding, and they are no longer repeated. If a high-grade polyester-colored masterbatch is prepared, such as a filamentary polyester masterbatch, it is generally considered to be a polyester soluble dye, which is preferably a carrier in the polyester itself.
