First of all you need to know what is non-woven fabric?

Nonwoven fabric is a fabric-like material made from staple fibre (short) and long fibres (continuous long), bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted.[1] Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non-wovens have become an alternative to polyurethane foam– From WIKI

1.Combine 3 layers non woven

Such 3 layers of non-woven raw materials, is stacked together by such a production machine as picture attached, Did you notice this little horn in the upper left corner of this machine? There was a thread that kept sending it through the horn.

2.Stitched into the nose clip

The second structure of the mask makeing: the bent metal on the upper part of the mask. You need to pinch the nose clip fixed to the nose beam when you wear it, so wearing a mask will be strict, otherwise without this structure, seal is not tight, affect the effect of protection

It is along the side of the non-woven fabric to match the delivery of wire, Rolls edge, Switch it as the same time.

3.Stitched into the nose clip

It depends on the second structure of the mask: the bent metal on the upper part of the mask. You need to pinch the nose clip fixed to the nose beam when you wear it, so wearing a mask will be strict, otherwise without this structure, seal is not tight, affect the effect of protection

4.Parts of layers

Such a mechanical design, there are three adjustable bevels, set a small bevel, so that a large area of nonwoven sloping along these bevels, from left to right gradually narrowed the “folding structure” to come.

Then there’s a folding pressure, guarantee surface of the mask is flattened.

5.Cut-out Process

The single cutting and seam edges of the mask are mostly fully automatic without manual handling. And the different masks are subtle manufacturing differences, some are seam slits, sometime it is hot-press glue.

6.Edge compression

Each side has a non-woven fabric to enhance and press the hanging rope, so as not to tear it off as soon as it pulls.

7.Hot pressure to fixed ear loop

In the edge of the face mask also need to use adhesive, on the following image of this side of the mechanical claws sent to the hanging ear loop, there is a hot adhesive on the homoze rope fixed on the mask, so that a flat mask even if the production is completed.

8.Sterilization

As picture show that batch of masks into the disinfection room, and then through the ethylene oxide gas (yellow below is for highlighting, in fact, colorless), reached a certain concentration after the completion of the disinfection process. After that, the air and nitrogen in the disinfection chamber to dilute and remove ethylene oxide, so many times, until the surface of the mask of ethylene oxide residue suppliced to the standard.

So it comes
