Antibacterial and antiviral non-woven fabric, preparation method of fabric and mask containing fabric

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...

AI Technical Summary

Problems solved by technology

[0003] But the masks of the prior art have the following problems: 1. The antibacterial and anti-virus functions cannot reach the expected effect; 2. The protective masks currently used are all disposable Sexual, can not be cleaned, use time is short, can not be reused, increase the cost of use, to a certain extent cause waste; 3. Existing masks lack the function of purifying harmful gases such as formaldehyde and benzene in the air

However, the mask has many layers and poor air permeability, so the anti-smog and epidemic prevention effects are not reflected.
