Manufacturing Method Of Anti-fog Mask

Existing masks generally use a plurality of rectangular non-woven fabrics or gauze and other materials stacked to form a mask body, and ring-shaped rubber cords are connected to both ends of the body. Ring-shaped rubber cords are hung on the ears on both sides of the user, so that the mask body covers the mouth and nasal cavity and other facial positions, playing a role of protection and filtering. However, because the breath that a person exhales contains a lot of water vapor, the nose bridge of the human face is convex. After wearing a flat mask, a gap will be formed on both sides of the nose bridge, causing a large amount of water vapor to rise through the gap on both sides of the nose bridge. White fog is formed on the glasses worn by the user, which affects the line of sight. When a large amount of exhaled air is discharged through the gap between the ordinary mask and both sides of the nose without being filtered, it will pollute the space environment with high hygiene requirements such as the operating room. For example, Chinese Patent Specification 201610720508.8 discloses a mask to prevent fogging of glasses. The inner layer of the mask body is equipped with gas-blocking silica gel near the upper part of the face side to prevent the exhaled water vapor from rising. However, medical workers often need it during work. Wearing a mask for a long time, a large amount of water vapor during breathing will cause a humid environment to form in the gap between the mask and the face. After a large amount of water vapor condenses on the non-woven fabric or gauze, the air permeability will be reduced, affecting the user's normal breathing, and the wet mask body will be close to the user's face, affecting the wearing comfort. Therefore, there is a need for a mask that can release mist and can be worn for a long time.
