The raw material of the mask is polypropylene (PP). The medical surgical mask is generally multi-layer structure, commonly referred to as SMS structure, as shown in Figure 1 and Figure 2.
The S in the mask layer stands for spunbonded fiber, with a coarse fiber diameter of about 20 microns (nm). The two layers of spunbonded fiber mainly support the whole non-woven fabric structure, and have no obvious effect on the barrier performance. The most important layer inside the mask is the barrier layer or melt-blown layer (M). The fibers in the meltblown layer are relatively thin, about 2 microns (M) in diameter, and thus only one-tenth the diameter of the spunbond layer, which is essential to keep bacteria and blood out of the layer.

The fibers of the spun adhesive layer, the meltblown layer, and the shape of the hair are compared. As shown in the figure, 1/3 of the diameter of the hair is close to the fibers of the spun adhesive layer, and 1/3 of the diameter of the hair is close to the fibers of the meltblown layer
