meltblown

Meltblown is a manufacturing process used to produce fine, lightweight nonwoven fabrics by extruding melted polymer (usually polypropylene) through tiny nozzles. As the molten material is stretched by high-velocity air, it forms a web of microscopic fibers that are collected on a surface. This process creates materials with a high surface area and small pore size, making them highly effective at filtering particles, such as in face masks and air filters. Meltblown fabrics are characterized by their softness, filtration efficiency, and flexibility, making them essential in medical and industrial applications.
