Types of non-woven masks
Non-woven masks are generally divided into two-layer non-woven masks, three-layer non-woven masks, and non-woven activated carbon masks.
1. The two-layer non-woven mask is made of two layers of 28-gram non-woven fabrics; the nose bridge is made of environmentally friendly all-plastic strips, does not contain any metal, and is equipped with vapor permeability, which is particularly suitable for electronic factories and daily life;
2. The three-layer non-woven mask is made of two layers of non-woven fabric and filter paper; the disposable three-layer mask is made of two layers of fiber non-woven fabric professionally used in medical and health, with an additional layer in the middle to prevent filtration More than 99.999% of the filter solution spray cloth is made by ultrasonic welding. The nose bridge is made of environmentally friendly all-plastic strips, does not contain any metal, and is equipped with steam permeation, which is comfortable. Filtration effect B.F.E up to 99.9%, especially suitable for electronics factories;
3. The non-woven fabric activated carbon mask is made of 28 grams of non-woven fabric on the surface layer, and the first layer in the middle is anti-bacterial filter paper with an anti-bacterial filter paper of more than 99.999%, which plays an anti-bacterial role and prevents viruses; the second layer in the middle is It is made of a new type of high-efficiency adsorption and filtration materials-activated carbon fiber and activated carbon cloth, which has the effects of anti-virus, anti-odor, filter bacteria and dust resistance;
