Today, the editor will give you a general introduction to the classification of commonly used masks on the market and the composition of non-woven fabrics in masks.

First of all, the more commonly used masks on the market are divided into two categories, namely flat masks and three-dimensional masks.


In terms of structure, flat masks generally consist of three layers, namely spunbond non-woven fabric-meltblown non-woven fabric-spunbonded non-woven fabric. real


It is the middle layer of melt-blown non-woven fabric that can filter, so the quality of the middle layer of melt-blown non-woven fabric will directly lead to the filtering effect of the mask.


A better three-dimensional mask is generally composed of five layers, namely spunbond non-woven fabric-melt blown non woven fabric-filter cotton-melt blown non woven fabric-spunbond non woven fabric. The two layers of meltblown non-woven fabric in the middle can make the three-dimensional mask have a very strong filtering effect and prevent PM2.5. But compared to flat masks, the air permeability of three-dimensional masks is relatively poor. So some three-dimensional masks with a higher price will

Equipped with breathing valve to ensure smooth breathing.
