What is melt blowing process?

Melt-blowing is a unique, one-step process in which the melt of a polymer emerging from orifices is blown into super-fine fibres by hot, high-velocity air.

A molten polymer is blown into ultrafine fibres and collected on a rotary drum or a forming belt with a vacuum underneath the surface to form a nonwoven web..

Is melt blown filter fabric washable?

As stated above, both mask filters have similar filtering performance at the time of first use, but after disinfecting and reusing, the nanofiber filter does not exhibit performance deterioration. In other words, nanofiber filters can be easily sterilized with ethanol at home and reused multiple times.

Is melt blown non woven fabric washable?

Nonwovens generally are not considered wash-durable, and more than a third of nonwovens today are used in durable applications that necessarily do not require laundering since most nonwovens inherently are considered “disposable” after one end-use application.

Why are n95 masks called that?

N95 masks are so called because they are a U.S. standard that requires masks to be able to filter out at least 95% of very small particles, including droplets containing the coronavirus.
