Meltblown is a manufacturing process used to create nonwoven fabrics. It involves melting plastic pellets, which are then extruded through fine nozzles to form thin fibers. These fibers are blown by hot air onto a conveyor belt, where they bond together to form a web-like structure. This process is commonly used to produce materials for filters, insulation, and medical supplies. The resulting meltblown fabric is known for its fine fiber structure, which provides excellent filtration properties. It is often used in products like face masks, including those made for COVID-19 protection, as well as in air filters and absorbent materials.
