Description
Technical Field
The utility model relates to the technical field of weaving, especially, relate to an antibiotic waterproof gas gauze mask.
Background
Air and water pollution, and the massive multiplication of germs or other bacteria bring great threats to the health of people. The mask is a convenient protection measure for protecting human from being invaded by germs. The mask is worn by people to provide a 'filtering barrier' for the respiratory tract, so as to filter the sucked air, and prevent a large amount of dust, bacteria, viruses, various harmful gases and the like which are mixed in the air from entering the human body. Meanwhile, some germs are extremely hard and are mainly transmitted by droplets and close contact, so when the mask has no function of killing germs or insufficient capability of killing germs, the safety protection performance of the mask is often improved by increasing the thickness of the mask. However, some stubborn germs still have the problem of insufficient safety protection performance, and if the worn mask is too thick, the air permeability of the mask is affected, so that people feel suffocating, and particularly after the mask is worn for a long time, the nasal mucosa is easily weakened, so that the original physiological function of the nasal cavity is lost, and other diseases can be induced.
At present, the common mask on the market is SMS or SMMS type (S: spun bond non-woven fabric; M: melt blown non-woven fabric), and the surface layer and the inner layer are non-woven fabric of polyester or polypropylene. Such masks have insufficient moisture absorption properties, and in use, the face becomes wet by moisture exhaled from the mouth, which can cause water mist to develop particularly on the lenses of the spectacles, and thus cause discomfort to the user, particularly the wearer. Meanwhile, the mouth and nose area is covered by the mask, so that the mask can be directly contacted with the oral cavity and the nasal cavity, and a large amount of water vapor and bacteria are generated when a human body breathes or speaks, so that the mask is easily contaminated on the mask, and the pollution of the mask is caused. And the bacteria can grow in a large amount under the relatively closed or ventilation-insufficient environment, thereby causing harm to human health. However, most of the existing protective masks use the principle of physical interception and filtration, that is, filter materials with certain pore sizes are used to filter and intercept the micro dust and aerosol particles larger than the pore sizes, so as to prevent pathogenic microorganisms (such as viruses, bacteria and the like) or other harmful factors attached to the micro dust and the aerosol particles from contacting with the human body and entering into the respiratory tract, thereby greatly reducing the risk of infection or harm to the human body. However, pathogenic microorganisms and other harmful factors intercepted and filtered are still attached to the mask filter material, and the common mask can only play a role in filtration and protection when being worn, but does not have an antibacterial function, so that the current market demand is difficult to meet.
Therefore, how to improve the waterproof, antibacterial and comfortable performances of the non-woven fabric mask is a technical problem to be solved urgently at present.
