What is Non Woven Fabric for Face Mask?

Cut a used medical mask, and you will find that the mask has three layers. Because in accordance with national production regulations, medical masks contain at least 3 layers of non-woven fabrics.

In fact, non-woven fabrics are composed of oriented or random fibers. Every family will have this material, and the most common one is the environmentally-friendly cloth bags that are kept in the elderly's homes.

Ⅰ. Medical face mask raw materials

Are these 3 layers the same? Of course not.

When making masks, all raw materials are polypropylene (PP), and medical masks are generally SMS structure. Among them, the spunbond layer is a single layer, and the meltblown layer can be divided into single layer or multiple layers according to filtration requirements.

"Meltblown cloth", commonly known as the "heart" of masks, is the filter layer in the middle of the mask. It has good filtering, shielding, heat insulation and oil absorption properties, and is an important raw material for the production of masks.

The two inner and outer spunbond layers of the melt blown cloth can protect sweat and water, and the middle meltblown layer can filter out bacteria, thereby preventing the spread of germs and reducing the occurrence of epidemic infections. Therefore, the manufacturing process of the meltblown layer is different from that of the spunbond layer.

Ⅱ. Comparison of medical mask raw materials and its production processes

Let's make a comparison: the fiber diameter of the S layer of the spunbond layer of the medical mask is about 1/3 of the hair, and the fiber diameter of the meltblown layer M is close to 1/30 of the hair. Only thinner fibers can ensure better antibacterial filtration.

In order to meet national requirements, polypropylene high-melt index non-woven fabric is the best choice for masks. It can also be used in disposable surgical gowns, sheets, covers, liquid-absorbent pads and many other medical supplies.

It is reported that 1 ton of high melting index fiber material can produce about 250,000 germ protection masks. With the supply of raw materials, the process of making masks is actually not complicated.

1. Lay the three layers of non-woven fabric material for mask together through the production machine;

2. Crimping, stitch the nose clip in;

3. Use a machine to make a large piece of mask non-woven fabric along the slope, gradually narrowing from left to right, to make a "folded structure";

4. Then pressing link to flatten the surface of the mask;

5. The individual cutting and seam of medical masks are mostly processed automatically without manual work;

6. Use non-woven fabric again to fill the edges of the mask;

7. It is necessary to cut and fill the edges again;

8. Fix the ear ropes by hot pressing.
