How are medical masks made
Composition and materials of medical masks:
1. Three layers of medical mask decomposition: the outer layer has anti-foam design (spunbond non-woven fabric) + middle layer filtration (meltblown non-woven fabric) + inner layer moisture absorption (spunbond non-woven fabric).
2. If you cut out the mask, you can see that there are at least 3 layers of non-woven fabric. The number of layers is required by production regulations, at least 3 layers.
Non-woven fabric (also known as non-woven fabric): It is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties.
Advantages: breathability, filterability, water absorption, water resistance, good feel, soft and light
Disadvantages: Poor durability compared to textile fabrics, not washable
