What is a melt-blown fabric?

Melt blown extrusion is a fabricating process that is taken to produce a type of material called non-woven fabric that is made of polymers including polypropylene, Polystyrene, Polyesters, Polyurethane, Polyamides (nylons), Polyethylene, Polycarbonate.

Melt-blown fabrics are used for several instances such as filtration, sorbents, hygiene products, apparel, and drug delivery.
To produce traditional fabrics that are made of natural materials like cotton, a process should be used in which the natural material first form into a yarn. After that, they are interwoven through a weaving or knitting process which leads to producing a sheet of traditional fabric.
On the other hand, non-woven fabrics do not evolve to the yarn by weaving or knitting and they need to be mechanically, thermally, or chemically bound together.
