Today, I will introduce you to theclassification of commonly used masks on the market and the composition ofnonwovens in masks.

First of all, there are two kinds of masks commonly used in the market, namely flat masks and three-dimensional masks.Below we will find two useful pictures for you to see.

In this construction, the planar mask isusually composed of three layers, which are spunbonded nonwoven fabrics -meltblown nonwoven fabric - spunbonded nonwoven fabric. It is the melt-blown nonwoven fabric of the intermediate layer that can really play the filter ingeffect, so the melt-blown nonwoven fabric(Nonwoven Face Mask Wholesale) of the intermediate layer will directly cause the filtering effect of the mask.

Better 3d masks(Disposable Face Mask Company) are usually composed offive layers, spunbonded nonwovens - meltblown nonwovens - filter cotton -meltblown nonwovens - spunbonded nonwovens. The middle two layers of meltblow nnon-woven fabrics(Medical Face Mask Supplier) provide a strong filtration effect on the three-dimensional maskand prevent PM2.5. However, the three-dimensional mask has poor gas permeability compared to a flat mask. Therefore, some higher-priced stereomasks will be equipped with a breathing valve to ensure smooth breathing.

In terms of specifications and standards,flat covers 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 intoN90, N95, and N99 European standards are generally divided into FFP1, FFP2, andFFP3.

It is worth noting that in a flat mask, thinnermost layer of nonwoven fabric will be treated hydrophilically to ensurethat the vapor generated by the breath can be adsorbed onto the nonwoven fabric.

The above is the composition,specifications and application standards of the non-woven masks.
