Melt Blown

Meltblown cloth, commonly known as the “heart” of the masks. It is the filter layer in the middle of the mask, which can filter bacteria and prevent the spread of germs. Melt-blown cloth is a film made of polypropylene with a high melt index. It is a film formed by laminating many criss-cross fibers in random directions. The fiber diameter ranges from 0.5 to 10 microns, and the fiber diameter is about 30 cents of the hair thread.
   
The melt blown process is a nonwoven manufacturing system. It is  involving direct conversion of a polymer into continuous filaments, integrated with the conversion of the filaments into a random laid nonwoven fabric.
The melt blown process  is a one-step process that converts polymer resin into low diameter fiber nonwoven web or tow (Andreas Desch, February 2011). The melt blown process, and its variants, is the only large-scale commercial process. It is presently being used to directly produce melt spun fibers with diameters in the submicron range without splitting or chemically dissolving away polymer.

Not All Masks Are Equal.

Many fashion brands start to making maks by using whatever material in hand. Are these masks helping to block? Medical-grade masks are made from specialized textiles. The variety favored in places such as hospitals (pdf) today isn’t woven like a typical fabric. It’s made by complex and expensive machines that form melted, synthetic fibers into an extremely fine web. This web allows air to pass through while filtering out particles, which is why this non-woven material is used in respirators such as those labeled N95 in the US or FFP2 in Europe (pdf). The labels refer to the certification processes the respirators undergo. N95 respirators, which are designed to fit so they form a seal around the nose and mouth, can block at least 95% of particles as small as 0.3 microns under testing.

Non Woven PP is never being so popular

So, why is the non-woven propylene material so popular?

The reason why polypropylene non woven masks are favored, mainly because it has the following advantages: good ventilation, non woven fabric breathable than other fabrics, and if the non woven fabric with filter paper in it, it’s filtering will be better; at the same time, non woven masks thermal insulation than ordinary masks, its water absorption, waterproof good effect; In addition, non-woven mask has good scalability, stretching even if it will not appear disheveled phenomenon , Its feel good, very soft, even if washed several times in the sun will not harden. Non woven masks flexible, long-term use can return to its original shape.
