Embodiment 1
[0066] This embodiment provides an antibacterial and antiviral non-woven fabric, the preparation method of which is as follows:
[0067] Mix 7 parts of nano-silver sol (the mass fraction of nano-silver is 8‰, and the average particle size is 10nm), 3 parts of nano-bismuth tungstate, and 2 parts of nano-titanium dioxide are mixed and dissolved in 30 parts of distilled water to form a sol. Soak in the sol, dry at 100°C, flatten, and roll to obtain the antibacterial and antiviral nonwoven fabric.
Embodiment 2
[0069] The difference with Example 1 is that nano-titanium dioxide is replaced with an equivalent amount of chitosan, and nano-bismuth tungstate is replaced with an equivalent amount of quaternary ammonium salt (trimethoxysilylpropyl dimethyl octadecyl ammonium chloride ), the drying temperature is 110°C.
Embodiment 3
[0071] The difference from Example 1 is that the nano-titanium dioxide is replaced by an equal amount of chitosan.

Abstract
The present invention relates to an antibacterial and antiviral non-woven fabric, a preparation method of the fabric and a mask containing the fabric. The antibacterial and antiviral non-woven fabriccontains nano-silver, and also contains an inorganic antibacterial agent and/or an organic antibacterial agent; the inorganic antibacterial agent comprises any one or combination of at least two of nano titanium dioxide, nano zinc oxide, bismuth tungstate and nano silicon dioxide; and the organic antibacterial agent comprises chitosan and/or quaternary ammonium salt. The mask sequentially comprises a first fabric layer, the antibacterial and antiviral non-woven fabric and a second fabric layer from inside to outside. While the air permeability is not affected, the mask is endowed with the long-acting antibacterial, anti-haze and antiepidemic antiviral properties, has the catalytic degradation function for harmful gases such as formaldehyde and benzene in air, and can be repeatedly washed with water to be recycled, thereby greatly reducing the use cost of the protective mask.
Description
technical field [0001] The invention relates to the technical field of mask processing, in particular to an antibacterial and antiviral nonwoven fabric, a preparation method thereof, and a mask containing the same. Background technique [0002] A mask is a commonly used sanitary protection product. With the rapid development of the industrialization process, the air pollution is becoming more and more serious, the air quality is deteriorating, and the frequent occurrence of haze weather poses a threat to people's health, especially for people who work outdoors for a long time. On the other hand, there are many kinds of viruses in the air. During the outbreak of infectious diseases such as influenza and bird flu, it is almost essential for people to wear masks when going out. Ordinary gauze or non-woven masks have been phased out due to their single function and inability to effectively isolate smog and viruses. Various masks with different structures are emerging, including...
