melt blown fabric
Melt blown fabric is the core material of the mask. Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure and good resistance to folds. The ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt-blown cloth has good filtration, shielding, heat insulation and oil absorption.
