Melt Blown Polypropylene Nonwoven Fabric Material

What is melt blown polypropylene fabric?     Polypropylene is abbreviated as PP. PP fibers obtained by polymerization of isotactic polypropylene of propylene, which is a thermoplastic resin, are used as non woven fabric raw material for spinning from synthetic fibers. Many everyday products are made of polypropylene plastic, such as transparent disposable lunch boxes, microwave containers, certain sports cups, etc.     Melt spraying ( melt blow molding ) is a nonwoven process through polymer extrusion. This is a filter material developed by the U.S. Navy in 1954 to collect radioactive particles from nuclear tests. Then around 1965, Exxon, 3M and other companies produced the first generation of melt spray nonwoven equipment.     The melt blown material is made by hot melting of its own fibers, and the thickness of the non woven fabric produced by the melt blown method is thicker. The randomness of the fibers…
