Melt spraying method is by the polymer particles after high temperature melting through melt spraying combined die extrusion, under the action of high temperature and high pressure airflow inside the spinneret, the melt fiber is sprayed and stretched into micro filaments, which are received by the negative pressure forming network to produce a kind of non-woven fabric with micro pores.
Fabric was implanted by electrostatic electrets to filter and block bacterial micro molecules.
It is generally used in the cuter layer of masks to support and filter large particles.
