The disposable mask covers the mouth, nose, and chin of a person, forming a sealed space between the medical mask and the face. People inhale when passing through a mask, forcing the air to filter out harmful substances to achieve a protective effect.
With the continuous development of science and technology, the continuous improvement of people's living standards and the increasingly serious environmental pollution, people's self-protection awareness is also increasing, and it is especially common to use disposable masks as protective equipment in non-woven masks.
At present, the types of masks circulating in shopping malls are generally divided into air filter masks and air supply masks. Air filter masks should be used more, such as dust masks, haze masks, and medical protective masks. Corresponding regulations have been issued for various types of domestic masks to regulate the mask market. Most of the specifications of protective filter masks implemented in China are mandatory product standards, and many items need to be tested. The air permeability of the fabric is the characteristic of the fabric itself, which is closely related to the fabric structure and fabric combination.
