The protective effect of non-woven protective masks is based on the effect of adsorbing fine dust (especially dust less than 5 microns). Because dust of this size can directly enter the alveoli, it has the greatest impact on human health. General gauze masks, the dust blocking principle is mechanical filtration, that is, when dust collides with gauze, it passes through layers of barriers to block ...

Melt blown cloth is mainly made of polypropylene, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, and good anti-wrinkle ability. These ultra-fine fibers with unique capillary structure increase the number and surface area offibers per unit area, so that the meltblown cloth has good filtration, shielding, heat insulation and oil absorption. . It can be used ...

Medical non-woven fabric is a fabric that does not need to be spun and woven. It is mainly bonded together directly by physical methods, so when you glue it, you will find that you cannot draw the thread from the non-woven fabric. It breaks through the traditional textile principle. Compared with traditional pure cotton woven textiles, medical non-woven fabrics are moisture-proof, breathable, flex...

Two-layer masks are very inferior. Medical masks must have three layers. Both sides of medical masks are usually spunbonded non-woven fabrics, and the middle is meltblown fabric. A good meltblown cloth is heavy enough. It looks white rather than transparent. It looks a bit like paper. The thinner the meltblown cloth, the worse the protective effect. The melt blown layer will melt when it encounter...
