Characteristics and classification of non-woven fabrics for masks


Today, I will introduce to you the classification of commonly used masks in the market and the composition of non-woven fabrics in masks.


First of all, there are two types of masks commonly used in the market, namely flat masks and three-dimensional masks. General flat masks usually consist of three layers, they are spunbond nonwoven fabric - meltblown nonwoven fabric - spunbond nonwoven fabric. What can really play the filtering effect is the melt-blown non-woven fabric in the middle layer, so the melt-blown non-woven fabric in the middle layer will directly lead to the filtering effect of the mask.


Better 3d masks usually consist of five layers, spunbond nonwoven - meltblown nonwoven - filter cotton - meltblown nonwoven - spunbond nonwoven. The two layers of melt-blown non-woven fabric in the middle can make the three-dimensional mask have a strong filtering effect and can prevent PM2.5. However, compared with flat masks, three-dimensional masks have poor air permeability. Therefore, some higher-priced three-dimensional masks will be equipped with breathing valves to ensure smooth breathing.


In terms of specifications and standards, flat shields 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.


3d masks are generally divided into American standards and European standards. American standards are generally divided into N90, N95, and N99 European standards are generally divided into FFP1, FFP2, and FFP3. It is worth noting that in the flat mask, the innermost non-woven fabric will be hydrophilic, which is to ensure that the steam generated by breathing can be adsorbed on the non-woven fabric.
