Planar face mask
Fold face mask
Breathing valve face mask
Face mask three-layer decomposition: the outer layer has anti-foam design (spinning non-woven fabric) middle filter (melt-sprayed non-woven fabric) inner layer moisture absorption (spinning non-woven fabric).
Note:25 grams of non-woven fabric is generally used
1. Non-woven fabric (outer layer): Non-woven fabric is non-woven fabric, which is made of fiber, relative to textile fabric.
2. Dissolved non-woven fabric (middle layer): This material is the principle of isolating germs. The main material is polypropylene, an ultra-fine electrostatic fiber cloth that captures dust (the droplets containing pneumonia virus will be electronically adsorbed on the surface of the non-woven fabric after being close to the melt-blown non-woven fabric, unable to penetrate).
3. Textile sticky non-woven fabric (inner layer): Non-woven fabric is relative to textile cloth, is non-woven cloth, is made of fiber.
