The washable mask membrane prepared by one-way or two-way stretching method has a spider web-like microporous structure on the surface. The three-dimensional structure has very complex changes such as network connectivity, hole nesting, and channel bending. Therefore, It has excellent surface filtration function.
Nano masks produced using this material have the characteristics of high barrier efficiency, long service life, lightness and breathability, and are a new direction for the development of masks in the future.
The respiratory impedance of washable mask membranes is only 60-70pa, while ordinary melt-blown non-woven masks are as high as 120-250pa. In comparison, the breathability of film masks is already very good, but it certainly cannot be compared to not wearing a mask. Compare.
The wearing comfort of a polytetrafluoroethylene film mask is mainly determined by the air permeability and moisture permeability of the mask.
Thin film masks have higher air permeability due to their material characteristics of high uniform distribution of holes; coupled with the moisture-proof and moisture-permeable characteristics of film materials, they can give users a more comfortable breathing experience.
