preparation example Construction

[0035] Wherein, the preparation method of the virus-killing non-woven fabric comprises the following steps:

[0036] S01. Prepare a composite metal wire rod by combining metal silver and copper, wherein, by weight percentage, silver is 40%-80%, and the rest is copper.

[0037] In a preferred embodiment, metal silver and metal copper wires are braided and rolled into a composite metal wire rod, wherein, by weight percentage, silver is 60% to 80% and the rest is copper.

[0038] S02. Use the composite metal wire rod as the anode conductor of the DC power supply to form an arc with the cathode. The temperature of the arc is above 5000°C, so that the tip of the metal wire rod of the anode conductor is vaporized and evaporated to produce smoky metal atom groups, silver metal atoms Fully mixed with copper metal atoms to form a gaseous alloy.

[0039] In a preferred embodiment, the composite metal wire rod is used as the anode conductor of the DC power supply to form an arc with the...

Embodiment 1

[0056] A method for preparing a virus-killing non-woven fabric, comprising the following steps:

[0057] S01, braiding silver metal wire and copper metal wire into a mixed metal wire with a diameter of 6mm, which is cold-rolled and rolled into a composite metal wire rod with a diameter of 5mm; wherein, in terms of weight percentage, silver is 40%, and the rest is copper. The purity of said metal silver and copper wire is 99.9%, and the diameter of said silver wire and copper wire is 0.4mm.

[0058] S02. Use the composite metal wire rod as the anode conductor of the DC power supply. Under the conditions of a DC voltage of 36 volts and a current of 1050 amps, an arc with a temperature of 5500 ° C and a length of 30 mm is formed with the cathode to make the tip of the metal wire rod of the anode conductor gas Evaporation produces smoky metal atom clusters, and the silver metal atoms and copper metal atoms are fully mixed to form a gaseous alloy. S03. Along with metal vaporizatio...

Embodiment 2

[0063] A method for preparing a virus-killing non-woven fabric, comprising the following steps:

[0064] S01. Weaving silver wire and copper wire into a mixed metal wire with a diameter of 7 mm, and cold rolling and calendering into a composite metal wire rod with a diameter of 5 mm; wherein, in terms of weight percentage, 60% of silver and the rest are copper. The purity of said metal silver and copper wire is 99.9%, and the diameter of said silver wire and copper wire is 0.5mm.

[0065] S02. Use the composite metal wire rod as the anode conductor of the DC power supply. Under the conditions of a DC voltage of 36 volts and a current of 1050 amps, an arc with a temperature of 5800 ° C and a length of 30 mm is formed with the cathode to make the tip of the metal wire rod of the anode conductor gas Evaporation produces smoky metal atom clusters, and the silver metal atoms and copper metal atoms are fully mixed to form a gaseous alloy.

Abstract

The invention discloses a virus-killing non-woven fabric, a preparation process thereof and a protective garment using the non-woven fabric. The non-woven fabric is made of a virus-killing polypropylene composite and is prepared from the following components in percentage by weight: 95-99 percent of polypropylene and the balance of a nano-silver-copper alloy material, wherein the nano-silver-copper alloy material is formed by mixing nano-silver-copper alloy particles with a particle size being 15-50nm, an atom form of copper metal on the outer surface of the alloy material is copper oxide, andthe nano-silver-copper alloy material is prepared from the following components in percentage by weight: 40-80 percent of silver and the balance of copper. For the protective garment using the non-woven fabric, detected that the antibacterial rates to escherichia coli and staphylococcus aureus representing conventional strains as well as methicillin-resistant staphylococcus aureus representing super bacteria all reach 99 percent or above.

Description

technical field [0001] The invention belongs to the field of non-woven materials, and in particular relates to a virus-killing non-woven fabric, a preparation process thereof, and protective clothing using the non-woven fabric. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, people's requirements for the quality of the environment are getting higher and higher. But at the same time of economic development, it also brought a series of environmental problems. For example, in smoggy weather, smog is mainly composed of sulfur dioxide, nitrogen oxides, and inhalable particulate matter. These fine particulate matter inhaled into the human body may cause great damage to the respiratory tract and lungs. Especially the SARS virus and the new coronavirus, which can be transmitted through droplets, contact and other ways. For medical staff and epidemic prevention personnel in hospitals, it is necessa...
