Face mask manufacturing processes
1. Combining: Three distinct non-woven textiles were layered neatly together by the laminator above on the production line's permanent support. A trumpet-shaped feeding port is located here, and a string of wires is continuously fed into the laminating machine through the trumpet.
2. Stitch: When wearing the mask, the nose clip must be pinched to the bridge of the nose in order for the mask to be secure and the protective effect to be maintained. The wire must be matched and conveyed down one side of the non-woven fabric, then the next edge must be rolled, the back must be stitched, and the wire must be stitched in.
3. Folding mask: Masks for adults are all the same size. It is ensured that different persons have the appropriate size needs in order to wrap the nose, lips, and chin to the maximum extent possible. It must then be flattened using a roller machine to create a crease for improved processing in future procedures. After that, it's trimmed down to a single mask unit.
4. Strengthen: This stage necessitates the use of additional non-woven fabric to press-fit the mask's edges. The excess non-woven fabric unites the single mask bodies that were cut in the previous stage at this point, so we must separate them once more.
Fixing the ear loop: It is vital to use adhesives at the four corners of the mask to improve the binding strength of the rope and the mask body. It is mechanically transferred during the pressing process. Hang the ear rope from the heat pressing equipment and adhere it to the mask with an adhesive.

5. Disinfecting: The mask will invariably become contaminated by germs during the entire manufacturing process, including not only the machine's processing contact but also the touch of many artificial linkages. Face mask manufacturer is aware of this. If it's just a regular mask, it doesn't need to be sterilised, but medical treatment necessitates the use of a ring. The steriliser for oxygen ethane (EO) has been sterilised. To achieve the goal of sterilisation, the mask was placed in an atmosphere containing 400 mg/L of ethylene oxide, and the hydroxyl group was alkylated to render the microbial macromolecules inactive.
Only medical masks made using the above procedure use high-melt melt-blown non-woven textiles for filter materials, electric treatment to promote electrostatic adsorption, disinfection with ethylene oxide after manufacture, and ethylene oxide analysis after 7 days. Masks made with this procedure is a certified, non-hazardous medical mask that can be used to prevent the spread of the new Covid variants.
