The "heart" of the mask-meltblown


From the steps of wearing a mask correctly, we basically understand that the role of the nose wire is to make the mask fit the face more perfectly, and to ensure that bacteria are not easy to enter the respiratory tract.

The nose wire structure needs to be well deformed by external force, does not spring back under no force, and keeps the existing shape unchanged. The nose wire is called the "backbone" of the mask.
