Back in 1945
During volcanic activity a fibrous material was drawn by vigorous wind from molten basaltic magma called Pete’s Hair. The event started the idea that became the same phenomenon that applies for melt blowing of polymers.
1950’s
The first research on melt blowing was a naval attempt in the USA to produce fine filtration materials for radiation measurements on drone aircraft in the 1950s. Later, Exxon Corporation developed the first industrial process based on the melt blowing principle with high throughput levels.
Fast Forward to 2018
China produces 40% of Melt Blown non-woven fabric in the world. Another innovation developed by a great American Company, Exxon Corporation left behind and passed over to to China to take over production. Leaving China as the top producer of Melt Blown Fabrics today.
Covid 19 enters USA 2020
The Covid 19 virus either originated in a Wuhan wet market or a Wuhan Infectious Disease Laboratory in 2019, both in China, as we all know. Today, China is the largest producer of this special Melt Blown raw material that is so critical to preventing the spread of moisture from human to human, which therefore also prevents the spread of the Respiratory Disease. From our work at Med Supply US we have seen the cost of this raw material go up 15 times. We have also seen Chinese shipping companies charging 7 times higher to ship goods then 6 months ago. Do your own research. We see it because we have to pay these bills. If anyone is Gauging the World, it is the Chinese Melt Blown and Respirator Factories and the Shipping Companies. The Chinese Economy has turned a complete 180 degrees all because of the Virus. Factories are buzzing, shipping routes are over crowded and full and China is needed by the World once again.
About Melt Blown Process By Wikipedia:
The porous non woven melt-blown fabrics can be used in the filtration of gaseous as well as liquid materials. These applications include water treatment, masks, air conditioning filter, etc. 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 and solvent-free operation.
