Medical masks generally use an SMS (spunbond-meltblown-spunbond) composite three-layer nonwoven fabric structure. The inner and outer layers are spunbond nonwoven fabrics, and the middle is a meltblown nonwoven fabric. The middle layer is mainly used to filter air. It is mostly made of PP non-woven fabric, and generally uses ultra-fine multi-layer fibers. The main purpose of this layer is to filter fine particles and is the blue source of common medical masks. The inner layer is mainly made of water-absorbing non-woven fabric. The main purpose of this layer is to absorb the water vapor exhaled by breathing. The mask has good air permeability, can block dust and water, avoid splashing liquid and spray from contacting the mouth and nasal cavity, and prevent infection between people.
