Anti-coronavirus non-woven fabric, preparation method thereof and mask comprising anti-coronavirus non-woven fabric

Abstract

The invention discloses an anti-coronavirus non-woven fabric, a preparation method of the anti-coronavirus non-woven fabric and a mask comprising the anti-coronavirus non-woven fabric, belongs to the field of mask processing, and discloses the anti-coronavirus non-woven fabric, the preparation method of the anti-coronavirus non-woven fabric and the mask comprising the anti-coronavirus non-woven fabric. The anti-coronavirus non-woven fabric contains nano-silver and further contains an inorganic agent and/or an organic agent; the inorganic agent comprises any one or a combination of at least two of nano titanium dioxide, nano zinc oxide, nano bismuth tungstate or nano silicon dioxide; the organic agent comprises chitosan and/or quaternary ammonium salt. The mask sequentially comprises a first fabric layer, the anti-coronavirus non-woven fabric and a second fabric layer from inside to outside. The mask is endowed with long-acting, anti-haze, anti-epidemic and anti-coronavirus performance while the air permeability is not affected, the mask has a catalytic degradation function on harmful gases such as formaldehyde and benzene in air, and can be repeatedly washed and recycled, and the use cost of the protective mask is greatly reduced.

Description

technical field [0001] The present invention relates to the field of mask processing, and more particularly, to an anti-coronavirus nonwoven fabric, a preparation method thereof, and a mask comprising the same. Background technique [0002] Masks are a commonly used sanitary protection product. With the rapid development of industrialization, air pollution has become more and more serious, air quality has continued to deteriorate, 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 a variety of coronaviruses in the air. During the outbreak of infectious diseases such as influenza and bird flu, it has become almost an indispensable link for people to wear masks when going out. Ordinary gauze or non-woven masks have been gradually phased out due to their single function and cannot effectively isolate smog and coronavirus. Various masks of different structures have ...

AI Technical Summary

Problems solved by technology

[0003] But the mouth mask of prior art has following problems: 1. anti-coronavirus function does not reach expected effect; The cost of use causes waste to a certain extent; 3. The 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.
