Problems solved by technology

Since some germs are very tenacious and mainly spread by droplets and close contact, when the mask does not have the function of killing germs or the killing ability is not strong enough, the safety protection of the mask can only be improved by increasing the thickness
Even so, it may not be completely safe for some stubborn bacteria, and if you wear a mask that is too thick, you will feel very stuffy, especially if you wear it for a long time, it will make the nasal mucosa weak and lose the original nasal cavity. Physiological function, but may cause other diseases

Embodiment 1

[0046] See Figure 1 and Figure 2. One layer of commercially available superamphiphobic barrier fabric layer 1, one layer of sterilizing and disinfecting fabric layer 2, one layer of absorbent antibacterial fabric layer 3, one layer of commercially available superamphiphobic barrier fabric layer 4 and two layers of commercially available contact protection The fabric layers 5 are stacked successively from the outside to the inside, and the materials are all cotton gauze. Cut into a rectangle of 18cm * 12cm, sew it up with sutures 6 along the inner 0.5cm of the edge, and then sew four corner bands 7 at four corners to obtain the mask 8 of the present invention. The air permeability of the mask made is very good, within the national standard. The antibacterial test adopts the Quinn method. Take one layer of sterilization and disinfection layer 2 and one layer of adsorption antibacterial layer 3, drop the bacterial liquid directly on the two layers of cotton yarn, cover with cul...

Embodiment 2

[0049] See Figure 1 and Figure 2. One layer of commercially available superamphiphobic barrier fabric layer 1, two layers of sterilization and disinfection fabric layers 2, one layer of absorbent antibacterial fabric layer 3, one layer of commercially available superamphiphobic barrier fabric layer 4 and two commercially available contact protection fabric layers 5. The materials are all non-woven fabrics and are stacked together sequentially from the outside to the inside. Cut into a rectangle of 18cm * 12cm, sew it up with sutures 6 along the inner 0.5cm of the edge, and then sew four corner bands 7 at four corners to obtain the mask 8 of the present invention. The air permeability of the mask made is very good, within the national standard. The antibacterial test adopts the Quinn method. Take two layers of sterilization and disinfection layer 2 and one layer of adsorption antibacterial layer 3, drop the bacteria solution directly on the three-layer non-woven fabric, cover...

Embodiment 3

[0052] See Figure 1 and Figure 2. One layer of commercially available superamphiphobic barrier fabric layer 1, one layer of sterilizing and disinfecting fabric layer 2, one layer of absorbent antibacterial fabric layer 3, one layer of commercially available superamphiphobic barrier fabric layer 4 and two commercially available contact protection fabric layers 5 are stacked together from the outside to the inside, the materials used are the 1st, 2nd, 4th functional fabric layers are polyester cloth, the 3rd functional fabric layer is non-woven fabric, and the 5th functional fabric layer is cotton gauze. Cut into a rectangle of 18cm * 12cm, sew it up with sutures 6 along the inner 0.5cm of the edge, and then sew four corner bands 7 at four corners to obtain the mask 8 of the present invention. The air permeability of the mask made is very good, within the national standard. The antibacterial test adopts the Quinn method. Take one layer of sterilization and disinfection layer 2...

Abstract

An antibacterial and antiviral mask is composed of a dual-layer isolating fabric layer, an antibacterial sterilizing fabric layer, an antibacterial adsorptive fabric layer, a dual-layer isolating fabric layer, and a protecting fabric layer, which are arranged sequentially from inner to outer and sewed together. Its advantage is high effect.

Description

technical field [0001] The invention belongs to the field of masks, in particular to a high-efficiency sterilization and anti-virus mask and a preparation method thereof. Background technique [0002] The pollution of air and water, the proliferation of germs or other bacteria pose a huge threat to people's health. Masks are a convenient protective measure used to protect humans from germs. People wear masks to set up a "filter barrier" for the respiratory tract to filter the inhaled air, so that a large amount of dust, bacteria, viruses and various harmful gases mixed in the air cannot enter the human body. Because some germs are very tenacious, and mainly spread by droplets and close contact, when the mask has no germ-killing function or the germ-killing ability is not strong enough, the safety protection of the mask can only be improved by increasing the thickness. Even so, it may not be completely safe for some stubborn bacteria, and if you w...
