Cut open an already used medical mask (new is fine, but I urge you not to waste it) and you will find: the mask has three layers.Because according to the national production regulations, the medical mask should contain at least 3 layers of non-woven cloth.

In fact, non-woven fabrics are non-woven and consist of directional or random fibers.Every family will have this material, the most common is the old people home often keep environmental protection cloth bags.

So are these three levels the same?Of course not.

All the raw materials used for making masks are Polypropylene (PP), and medical masks are generally shortened to SMS.The spunbonded layer is a single layer, and the molten spray layer can be divided into a single layer or multiple layers according to the filtration requirements.

 "Melt spray cloth", commonly known as the "heart" of the mask, is the filter layer in the middle of the mask, with good filtering, shielding, thermal insulation and oil absorption, is an important raw material for the production of masks.

As can be seen from the schematic diagram, the internal and external spunbonded layer can protect sweat and water, while the molten spray layer in the middle can filter out bacteria, so as to prevent the spread of germs and reduce the incidence of epidemic infection.Therefore, the production process of molten spray layer is different from that of spunbonded layer.

Let's make a comparison. The fiber diameter of the spunbonded layer S is about 1/3 of that of the hair, and the fiber diameter of the fused spray layer M is close to 1/30 of that of the hair. The finer fibers ensure better antibacterial filtration.

In order to meet the national requirements, polypropylene high melting point non-woven fabric special material becomes the best choice of mask, it can also be used in disposable surgical clothes, sheets, covers, liquid absorption pads and other medical supplies.

It has been reported that one ton of high-melt finger fiber can produce about 250,000 bacteria protective masks.With the supply of raw materials, the process of making masks is not complicated.

First of all, three layers of non-woven fabric raw materials are laminated together by a production machine.

Roll the edges and put the nose in.

Make a "folding structure" by making a large piece of non-woven cloth narrow from left to right along the inclined plane.

Then there is the pressing part, which flattens the mask surface.

The single cutting and sewing edge of the mask are mostly automatic without manual treatment.

Then use non-woven cloth to fill the edge of the mask.

So we need to cut and mend again.

Then by means of hot pressing, fix the lug rope, and basically you're done.
