99% MELT BLOWN: Melt blown extrusion is a manufacturing process that is used for creating a type of fabric called non-woven fabric which is made from polymers such as polypropylene. Traditional fabrics made of natural materials like cotton are woven together, meaning that the material is first formed into a yarn and then interlaced using a weaving or knitting process that results in the creation of a sheet of fabric from the yarn. Non-woven fabrics do not involve joining yarn by weaving or knitting; instead, they mechanically, thermally, or chemically bound together material created from separate fibers of molten polymers forming a web-like fabric.
