Is the disposable mask three-layer or four-layer better?

The fourth floor is better. Disposable medical masks in daily life are made of more than three layers of 28 grams of non-woven fabrics. The bridge of the nose is made of environmentally friendly plastic strips. It does not contain any metal. It is breathable and can prevent respiratory tract infections to a certain extent. Generally, most disposable medical masks on the market are three-layered. They are made of two layers of fiber non-woven fabrics used in medical and health care. An additional layer is added in the middle to filter and prevent bacteria by more than 99%. Ultrasonic welding is enough to prevent viruses, but a four-layer disposable mask has a better natural effect due to more layers, but at the same time, the air permeability will also become worse.

The difference between three-layer and four-layer disposable masks

The three-layer mask with different structures is divided into an inner layer, an outer layer and a middle layer. The outer layer has a water barrier function, the inner layer has a moisture absorption function, and the middle layer has a fine structure, which can block adsorption, kill and filter viruses, particles, droplets, Germs, etc., can achieve clinical prevention and treatment effects. The four-layer mask has one more layer to strengthen the isolation coefficient and filtering function of the mask. The four layers of different applicable occasions can be used in special occasions, such as doctors, front-line nurses, medical staff, etc., with stronger isolation, adsorption, and filtering functions, and stronger prevention capabilities, three-layer masks can also prevent viruses, but more It is suitable for the general public to prevent viruses.

Activated carbon and melt blown cloth mask which is better

Melt blown cloth is better. Under normal circumstances, most of the activated carbon masks in life are not anti-virus. Even if they are anti-virus, the protective effect of activated carbon masks is not as good as that of melt blown cloth. Because the structure of the melt blown cloth mask is non-woven fabric + melt blown cloth + non-woven fabric, the structure of activated carbon mask is non-woven fabric + activated carbon + non-woven fabric, which means that the melt blown cloth in the mask is used to block bacteria If there is no melt blown cloth in the activated carbon mask, the ability to protect against viruses is relatively poor. Because the filtering capacity of the activated carbon layer is much worse than that of the melt blown cloth, it is only suitable for daily dust prevention, so the melt blown cloth has a better protective effect than the activated carbon mask.

Which is better for mask non-woven fabric or meltblown fabric

Although the protective effect of gauze-free masks is also very good, it is less effective than melt blown cloth, because melt blown cloth is mainly made of polypropylene as the main raw material, which is the core material of the mask, and the fiber diameter can reach 1-5 microns. , It has many voids, fluffy structure and good anti-wrinkle ability. The ultrafine fiber with unique capillary structure increases the number and surface area of fiber per unit area, and has good filtering, shielding, heat insulation and oil absorption. The gauze-free mask is made of two layers of fiber non-woven fabric that is professionally used for medical and health care, and a layer of filter melt spray cloth with a filtering and antibacterial effect of 99.99 9% or more is made by ultrasonic welding, which can meet the protection requirements in daily life. Demand, but melt blown cloth can meet the use of higher-level places.
