Technical Field

The invention relates to the field of protective articles, in particular to a reusable mask made of high-density wool fabric.

Background

At present, respiratory infectious diseases in China and even in the whole world are serious, the main transmission ways are droplet transmission and respiratory transmission, so that people need to ensure the safety of respiratory passages, and the mask is a main means for preventing the respiratory infectious diseases and can play a role in blocking virus infection. Aiming at infected patients, the mask can prevent virus from spreading, reduce the pollution to the environment, prevent infection and the chance of infection to other people, so that the selection of the mask with better quality is very important. The old and middle school teachers in China call for people to carry masks when going out, so that the masks become the most popular products in the market at present. People find out to rob the mask in many times, and the phenomena of shortage of raw materials for manufacturing the mask, shortage of personnel and the like appear in the market at one time.

In the market, disposable masks are rich in types and low in price, but need to be replaced in time according to needs. For example, in general areas, the replacement is required to be carried out once in 4-6 hours, and in areas and places with serious epidemic diseases, the replacement is required to be carried out once in 2-3 hours. The replaced mask can not be reused, and a great deal of disposable masks are discarded, so that huge waste of resources is caused. Meanwhile, the existing classification level of the garbage in China is far from meeting the requirement of discarding and processing the disposable mask, and huge pressure and gaps exist in the separation and processing, so that certain social hidden dangers are caused.

In addition, from the use experience of consumers, the disposable mask is made of universal size and chemical fiber non-woven fabric, and the comfort performance is poor. Meanwhile, the existing disposable mask is not distinguished from medical protective products in the aspect of appearance, and the distance between people is kept from the sense of the appearance.
