Mask Composition

The three-layer masks (SMS structure) we wear most often are generally composed of meltblown cloth, spunbonded cloth, mask belt, and nose clip. The outer and inner layers are made of spunbonded cloth, and the middle layer is made of meltblown cloth (filter paper). The nose clip is made of soft foldable thin rubber strips embedded in the non-woven fabric, and the mask belt is made of elastic spandex. The most important thing to isolate the virus is the middle meltblown cloth.
