Mask production process

The whole production process of masks is still relatively numerous, especially the follow-up disinfection link. This is why a mask is made in 0.5 seconds, so the rapid production efficiency is still the reason for the shortage of masks. Understanding the production process of masks begins with the composition of the mask , We cut a medical mask, you can find that the mask has three layers of non-woven fabrics, which is also required by the national standard of medical masks, otherwise it will not meet the protection requirements.

Medical mask is generally referred to as SMS structure

For the production of masks, the raw materials and fibers are all polypropylene (Polypropylene, PP), and medical masks are generally referred to as SMS structures. The spunbond layer is a single layer, and the meltblown layer is divided into a single layer or multiple layers according to filtration requirements. “Melt-blown cloth”, commonly known as the “heart” of the mask, is the filter layer in the middle of the mask. It has good filterability, shielding, heat insulation and oil absorption, and is an important raw material for the production of masks.

Polypropylene high melting point non-woven special material becomes the best choice for masks. It can also be used in disposable medical gowns, sheets, drapes, liquid absorption pads and other medical supplies. These materials all come from some chemical companies such as Sinopec, Qilu Petrochemical, Zhenhai Refinery, Maoming Petrochemical and so on.

With the supply of raw materials, the process of making masks is less complicated:
