Meltblown Nonwoven is a fabric formed from a melt-blowing process that extrudes and draws molten thermoplastic resin from an extruder die with high-velocity hot air to superfine filaments deposited onto a conveyor or moving screen to form a finely fibrous and self-bonding web. The fibers in the melt-blown web are laid together by a combination of entanglement and cohesive sticking.
The Meltblown Nonwoven Fabric is mainly made of polypropylene resin. The melt-blown fibers are very fine and generally measured in microns. Its diameter can be 1 to 5 microns. Owning to its ultra-fine fiber structure that increases its surface area and the number of fibers per unit area, it comes with excellent performance in filtration, shielding, heat insulation, and oil absorption capacity.
