Introduction to the composition, specifications and application standards of non-woven fabrics for m

2021-06-07 15:53:47
Today, the editor will give you a general introduction to the classification of the more commonly used masks on the market and the composition of the non-woven fabrics in the masks.

First of all, the more commonly used masks on the market are divided into two categories, namely flat masks(N95 Fabric Factory) and three-dimensional masks.

In terms of structure, flat masks generally consist of three layers, namely spunbonded non-woven fabric-meltblown non-woven fabric-spunbonded non-woven fabric. It is the middle layer of melt-blown non-woven fabric that can really 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(Mask Fabric Factory) 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 can prevent PM2.5. However, compared with flat masks, the air permeability of three-dimensional masks is relatively poor. Therefore, some higher-priced three-dimensional masks will be equipped with breathing valves to ensure smooth breathing.

In terms of specifications, flat masks are generally divided into three standards, 1. BFE95/99 bacterial filtration efficiency standard 2. VFE99 virus filtration efficiency standard 3. PFE99 particle filtration efficiency standard.

Three-dimensional masks are generally divided into American standard and European standard. American standard is generally divided into N90, N95, and N99. European standard is generally divided into FFP1, FFP2, FFP3

It is worth noting that on flat masks, the innermost layer of non-woven fabric will be treated with hydrophilic treatment to ensure that the water vapor generated by breathing can be absorbed on the non-woven fabric.

The above is the introduction of the composition, specifications and application standards of non-woven fabrics for masks(Electrostatic Filter Company) compiled by the editor.
