Spunbonded meltblown Fabric Filter Materials

PP Spunbonded Nonwoven Fabric Filter Materials Replaces Meltblown


The core material of the film mask is PTFE nano film, and the film fiber diameter is between 100 and 200 nanometers. The film mask made of this material has the following three characteristics:


1. Higher blocking efficiency. Mainly because the fiber diameter of the material used is smaller than that of traditional materials (the fiber diameter of the non-woven fabric used in traditional masks is more than 1000 nanometers), it can effectively block PM2.5 in the air (the aerodynamic equivalent diameter is less than or equal to 2500 nanometers) Particulate matter), and effectively reduce the concentration of bacteria and viruses in the air;
 
2. the service life is longer. The reason is that it uses physical principles to isolate air pollutants and is more durable (nonwoven fabric materials used in traditional masks need to rely on static electricity to adsorb particulate matter due to the large fiber diameter. Invalid, so it can only be used once);
 
3. Breathe more easily and freely when wearing. This is mainly determined by the better air permeability and moisture resistance of the nano film.
 

Option

Nano film

Meltblown

Structural features

The fiber diameter is 0.1 to 0.2 microns, that is, 100 to 200 nanometers, ultrafine fibers, complex pore structure, can provide absolute filtration accuracy, large total adsorption area, high filtration effect

The average fiber diameter is 2 microns, the total adsorption area is small, and the filtering effect is not good

Applicability

The PTFE membrane is naturally hydrophobic, and the filtration mechanism is pore size interception, which will not attenuate the filtration effect due to breathing and moisture. Compared with ordinary melt-blown cloth masks, its electrostatic adsorption protection effect is more durable.

Mainly rely on static electricity to adsorb particles, breathing easily makes the mask wet, the static electricity will continue to weaken, and the protection efficiency is reduced, so experts recommend replacing the mask every 4 hours

Comfort

The PTFE membrane will not lose fibers through the overall stretching process, and has an ultra-thin thickness of less than 5 microns. After composite non-woven fabric, the total thickness does not exceed 100 microns, which is more suitable for wearing

The thickness of the melt-blown non-woven fabric is about 150 microns, which is relatively thick. The melt-blown film is brittle and the fibers are easy to fall
