The electret master batch is a material prepared by adding an additive (tourmaline) with a charge storage function according to a certain proportion and a processing technology. The tourmaline itself has charge, can release negative ions for a long time under certain conditions, and has to generate micro charge under the excitation of an initiator, so that the electret machine is necessary to charge and store energy in the early stage. Tourmaline powder with nanometer size has high fiber fusion degree, and is dispersed and pre-enveloped in organic insulating material. The electret masterbatch can be used in the production of meltblown nonwoven fibers.

In order to prevent particles from being generated during melt blowing, the electret master batch for the prior melt-blown nonwoven fiber needs to be subjected to mixing treatment.
