Melt-blown cloth is the core material of the mask. The melt-blown cloth is mainly made of polypropylene, and the fiber diameter can reach 1 ~ 5 microns. The microfibers with unique capillary structure increase the number and surface area of the fibers per unit area, so that the melt-blown cloth has good filtering, shielding, insulation and oil absorption. It can be used for air and liquid filtration materials, isolation materials, absorbing materials, mask materials, thermal materials, oil absorbing materials and wiping cloth and other fields.


No matter whether the cloth used is thick or thin, cotton or silk, if the mask has only two layers inside and outside, without the melt-blown cloth in the middle, it will not be able to prevent particles and bacteria.


Theoretically speaking, if the number of layers is increased, the filtering efficiency of the melt-blown cloth mask will be improved appropriately, that is, the ability to intercept micro-particles will be better, but the suction resistance of the mask will be greatly increased, and the wearer will feel "stuffy". Choose the right melt-blown cloth mask, one layer can achieve a good protective effect, there is no need to blindly pursue a double layer of melt-blown cloth.
