Performance characteristics of PFE99 Melt-blown Fabric

Performance characteristics of PFE99 Melt-blown Fabric

(Summary description)What is PFE99 Melt-blown Fabric? PFE99 Melt-blown Fabric refers to a melt blown fabric with a filtration level of 99%. The filtration efficiency here generally refers to a particle detection of 99%, which is PFE detection. Let's simply say that this PFE test is like passing air containing tiny particles through a melt blown cloth.

What is PFE99 Melt-blown Fabric? PFE99 Melt-blown Fabric refers to a melt blown fabric with a filtration level of 99%. The filtration efficiency here generally refers to a particle detection of 99%, which is PFE detection. Let's simply say that this PFE test is like passing air containing tiny particles through a melt blown cloth.

PFE99 Melt-blown Fabric

The degree of completion that the meltblown cloth can intercept, 100% of the particles is the best, the particles can not pass through, such a meltblown cloth can play a very good role as the filter layer of the mask, but it is impossible to achieve 100% , The current grade 99 PFE99 Melt-blown Fabric is the highest standard. But this standard is also very high.

For example, for our medical surgical masks, the filtration requirement for PFE particles is not less than 30%. Many people are surprised. No, this is too dangerous. Most of them are not filtered out. Doesn't it provide protection after breathing?

This is about a meltblown cloth and another test item, the bacterial filtration test, that is, the BFE test. The working environment of medical surgical masks is mainly to filter viruses, bacteria, etc., and there are basically no particulate harmful substances in the air. , The BFE filtration required by medical surgical masks should not be less than 95%. That is to say, the filtration efficiency of melt blown cloth should also be divided into filtering objects, but we usually call 90.95.99 to describe melt blown cloth, generally it is Refers to PFE99, which is the filtering effect of particle detection.

How

How the Melt-blown fabric is constructed

The following paragraph of this article will introduce the related production process of Melt-blown fabric. The production process of Melt-blown fabric is mainly divided into three steps: melt extrusion, melt-blown process, and electret treatment. Specifically, Melt-blown fabric uses high-speed hot air flow to draw the extruded polymer melt through the spinneret holes of the die nozzle. From this, microfibers are formed and collected on a condensate screen or drum, and at the same time self-bond to become a Melt-blown fabric.

Reasons

Reasons why Melt-blown fabric becomes brittle after production

1. If the aspect ratio of the spinneret of Melt-blown fabric is small, the holes are thick and short. After the polymer is sprayed, the fibers are thicker, the gaps are larger, and the water absorption is stronger for a long time , so the Melt-blown fabric is neither soft nor brittle.

The features of BFE 99 masks

BFE in BFE 99 masks means bacterial filtration effect, which refers to the material's resistance to bacterial penetration. The reported results of BFE 99 masks are shown in percentage data, corresponding to the ability of the material to resist bacterial penetration. The higher the value, the better its filtration performance.
