Melt-blown fabric is a kind of ultrafine fiber non-woven material made by melt-blown process, raw material is food grade PP, fibre diameter can be 0.5um-2um.
Our Melt-blown meet BFE99 standard，applications include disposable surgical face masks, gas
filtration, clean room pocket filters and more.
For example，the medical face mask has three layers, and the meltblown cloth is
the middle layer. It has strong filtering, shielding, and thermal
insulation properties. It can play the role of sterilization and virus
isolation. It can be said that it is the heart of a medical mask.
Both the inner and outer layers of the medical mask are only
supporting functions. The most important thing for filtering viruses is
the middle melt-blown cloth. The ordinary melt-blown cloth has a
filtration efficiency of 50%. It needs to be reprocessed to increase
electrostatic adsorption before bacterial filtration can reach more than
99% ( (Referred to as BFE99) 50% filter efficiency meltblown cloth can
only be used as a civilian protective mask, only dust, dust, and can not
isolate viruses, but all medical masks, surgical masks must use 99%
filter efficiency meltblown cloth .
In the chain of medical masks, meltblown fabrics, special materials
for meltblown fabrics, and raw materials, special materials are the most
important links. The main raw material for the production of special
materials for meltblown cloth is polypropylene (Polypropylene), and the
material supply mainly comes from Sinopec.
