Medical masks are generally of three-layer (non-woven) structure, which are made of two layers of spunbonded non-woven fabric used for medical and health care, and one layer is added in the middle of the two layers, which is made of solution sprayed non-woven fabric with more than 99.999% filtration and anti bacteria by ultrasonic welding.

Three layer decomposition of medical mask: outer layer with anti droplet design (spunbonded non-woven fabric) + middle layer filtration (melt blown non-woven fabric) + inner layer moisture absorption (spunbonded non-woven fabric).

Note: melt blown non-woven fabric is generally 20 grams

Spunbonded non-woven fabric (outer layer): non woven fabric is a non-woven fabric, which is composed of fibers, relative to textile fabric.

Advantages: ventilation, filtration, water absorption, waterproof, good handle, soft, light

Disadvantages: can’t clean

Solution spray non-woven fabric (middle layer): this material is the principle of isolating bacteria. The main material is polypropylene, which is a kind of ultra-fine electrostatic fiber cloth, which can capture dust (the droplets containing pneumonia virus will be electrostatic adsorbed on the surface of the non-woven fabric after they are close to the melt blown non-woven fabric, which cannot be penetrated).

Spunbonded non-woven fabric (inner): non woven fabric is relative to textile fabric, that is, non-woven fabric, which is composed of fibers.

Advantages: ventilation, filtration, water absorption, waterproof, good handle, soft, light

Disadvantages: can’t clean
