What is melt blown nonwoven fabric

Melt blown nonwoven fabric is a filter material with polypropylene as the main raw material. The fiber diameter can reach 1 to 5 microns. These ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown non-woven fabric has good 

filtration, shielding, heat insulation and oil absorption. It can be used in the fields of air, liquid filter materials, isolation materials, absorbent materials, mask materials, thermal insulation materials and wipe cloths.

Melt blown nonwoven fabric is the core material of masks. Medical masks and N95 masks are composed of a spunbond layer, a meltblown layer and a spunbond layer. The spunbond layer and the meltblown layer are all made of polypropylene PP material.
