Disposable masks are made of more than three layers of non-woven fabrics. The bridge of the nose adopts the environment-friendly plastic strip, which does not contain any metal, breathable and comfortable. Especially suitable for electronic factories, daily life use. Disposable face masks (medical-surgical masks) can prevent respiratory infections to a certain extent, but they cannot prevent haze. The advantage is that it has very good ventilation, it can filter toxic gases, it can be waterproof, it is stretchable and will not be messy, it feels very good and quite soft. Compared with other masks, the texture is relatively light, very elastic, and can be reduced after stretching. The price is very cheaper, only for one-time use. The disadvantage is that compared with other cloth masks, disposable masks cannot be cleaned. Because the fibers are arranged in a certain direction, they are easy to be torn apart. Compared with other textile masks, disposable masks are weaker in strength and durability than other masks.
