May 29 2020Protective face masks are classified as PPE in the EU and are subject to the requirements of Regulation (EU) 2016/425 and performance tests according to EN 149:2001+A1:2009 The Chinese counterpart is GB 2626-2019 but it is not equivalent to EN
For basic infection control this non-woven fabric bonds fibers together to form a single layer that is appropriate only for very minimal fluid exposure Balanced mix of protection and comfort Strong and breathable Spunbond/Meltblown/Spunbond (SMS) is a multi-layer fabric composed of inner layers of meltblown polypropylene between outer
Melt blowing is a conventional fabrication method of micro- and nanofibers where a polymer melt is extruded through small nozzles surrounded by high speed blowing gas The randomly deposited fibers form a nonwoven sheet product applicable for filtration sorbents apparels and drug delivery systems The substantial benefits of melt blowing are simplicity high specific productivity [jargon
Apr 22 2020Most of the traditional filter materials are ordinary melt-blown non-woven fabrics etc which has a poor filtering effect and cannot effectively filter the tiny particles and bacteria in the air after research the electret process is used that is: adding electret materials And the non-woven polypropylene non-woven fabric with high electret treatment has high filtration efficiency

Spunbond and non-woven fabrics are affiliation There are many production processes for the manufacture of non-woven fabrics among which the spunbonding method is one of the non-woven fabric production processes (including the spunbonding method the melt-blown method the hot-rolling method and the leeches method which are mostly on the market) ) Non-woven fabrics produced by
The key difference between the spunbonded process and melt-blowing is in the die assembly In the melt-blown process hot air converges with the fiber as it emerges from the die whereas in the spunbond process the hot air flow is at a cross flow to the emerging fiber
