Mask with antibacterial and antiviral functions and preparation method thereof

Abstract

The invention provides a mask with antibacterial and antiviral functions, which comprises a mask main body and hangers arranged on two sides of the mask main body, wherein the mask main body comprises an outermost layer, a secondary outer layer, a middle layer and an inner layer. The antibacterial and antiviral treatment of the secondary outer layer comprises the steps of a, selecting a spunbond non-woven fabric made of polypropylene or polyethylene; b, conducting hydrophilic finishing; and c, conducting antibacterial and antiviral finishing. The mask with the antibacterial and antiviral functions is made of the multiple layers of non-woven cloth, compared with an existing common mask, the mask body further comprises the antibacterial and antiviral non-woven cloth layer, an adopted antibacterial agent is non-toxic, environmentally friendly and safe, the antibacterial and antiviral non-woven cloth layer has an excellent killing effect on germs and viruses, the layer does not make direct contact with the skin, the safety is high, and the mask is easy for industrial mass production, simple in production process, short in flow and low in cost.

Description

technical field [0001] The invention relates to a mask, in particular to a mask with antibacterial and antiviral functions and a preparation method thereof. Background technique [0002] At present, the main body of ordinary masks commonly used in the market mainly has a three-layer structure, which are the outer layer of dust-proof non-woven fabric layer, melt-blown non-woven fabric layer, and skin-friendly non-woven fabric layer. The meltblown nonwoven fabric layer can absorb and block particles, germs and viruses through electrostatic adsorption and filtration, which belongs to physical barrier function. Viruses and bacteria that are filtered and adsorbed can still survive. For example, in an environment with a relative humidity of about 65% at room temperature (22°C), surgical masks can survive for more than 7 days. During use, with the continuous exhalation of water vapor from the mouth and nose, the charge of the melt-blown cloth that has been treated with electret is...
