(Summary description)The main structure of the Melt-blown wipes for medical mask is a three-layer non-woven fabric, namely the SMS structure. The inner S layer is an ordinary non-woven fabric, mainly for the function of moisture absorption; The outer S layer is a non-woven fabric with waterproof treatment, which is mainly used to isolate the liquid sprayed by the patient and has the effect of preventing droplets; The middle M layer uses electret-treated Melt-blown wipes non-woven fabric, which can filter suspended bacteria and is the most important core layer.

Frist, what is the structure of Melt-blown wipes?


The main structure of the Melt-blown wipes for medical mask is a three-layer non-woven fabric, namely the SMS structure. The inner S layer is an ordinary non-woven fabric, mainly for the function of moisture absorption; The outer S layer is a non-woven fabric with waterproof treatment, which is mainly used to isolate the liquid sprayed by the patient and has the effect of preventing droplets; The middle M layer uses electret-treated Melt-blown wipes non-woven fabric, which can filter suspended bacteria and is the most important core layer.

Melt-blown wipes Wholesale Price

Melt-blown wipes, commonly known as the "heart" of masks. Its main raw material is polypropylene, a film made of many criss-cross fibers stacked in random directions. The fiber diameter ranges from 0.5 to 10 microns, and the fiber diameter in Melt-blown wipes is about one-third the size of a human hair.

After reading the previous paragraphs of this article, do you still have some doubts? Melt-blown wipes have such a large gap, how do they filter viruses in the environment?

The use of Melt-blown wipes takes the novel coronavirus as an example, although the size of the novel coronavirus is very small, around 100 nanometers (0.1 microns). However, the virus cannot exist independently. The main transmission routes are secretions and droplets from sneezing. The size of the droplets is about 5 microns. This is one of them. Second, Melt-blown wipes are essentially a fiber filter. , After the droplets containing the virus are close to the meltblown cloth, they will also be electrostatically adsorbed on the surface and cannot be penetrated.

Through the above introduction and analysis of Melt-blown wipes, hope it helps you.

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.
