Different functional masterbatches have different properties when pigments are selected. The following describes the function of masterbatch
The most basic requirements for the heat-resistant masterbatch pigments， the most basic requirements can withstand the temperature of the polypropylene fiber production process, to maintain its performance is stable, The temperature resistance temperature is generally required to be 270 ~ 280 ° C or more
The pigment for the disperse masterbatch should be excellent in dispersibility. and should be uniformly dispersed in the masterbatch. and the dispersant used does not reduce the quality of the polypropylene fiber, Otherwise, the quality of the raw liquid colored fiber cannot be produced, and the operation is unstable； It is easy to break or produce abnormal fibers when drafting fibers
