Meltblown cloth 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 fold resistance. 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 filterability, shielding, heat insulation, and oil absorption.

Meltblown cloth can be used in the fields of air, liquid filter materials, insulation materials, absorption materials, mask materials, thermal insulation materials, oil-absorbing materials and wipers.
