Medical masks are mostly made of one or more layers of non-woven fabrics. The main production process of medical masks includes meltblown, spunbond, hot air or acupuncture, etc., which is equivalent to resisting liquids, filtering particulates and bacteria, and is a medical protective textile.

Composition and function of Medical Masks
The medical masks are composed of a mask face and a tension band. The face mask is divided into inner, middle and outer layers. The inner layer is ordinary sanitary gauze or non-woven fabric. Non-woven fabric or ultra-thin polypropylene meltblown material layer. This highly effective medical protective mask is highly hydrophobic and breathable, and has a significant filtering effect on tiny virus aerosols or harmful dust. The overall filtering effect is good, the materials used are non-toxic and harmless, and they are comfortable to wear.
Medical Masks can prevent infections caused by airborne diameter ≤ 5μmg infectious agents or close-range (≤ 1m) exposure to droplet-borne diseases. The particle filter efficiency of the mask filter should be no less than 95%, and the protection level is high.
Scope of application
Medical masks are better protective equipment. It is recommended to wear them when there is serious environmental pollution or medical infectious diseases (such as respiratory infections).
☆ Individual protection of military biochemical weapons
