Description

Long-acting antiviral fabric and mask formed by same

Technical Field

The utility model relates to the field of articles for daily use, concretely relates to antibiotic fabric and adopt gauze mask that this fabric constitutes.

Background

There are many ways to make the fabric itself antiviral, and most commonly, chemical substances capable of killing viruses are provided on the fabric, such as: halogen (chlorine-containing disinfectant), metal (silver nitrate), quaternary ammonium compound, alcohol, and the like used in conventional antibacterial methods. Conventional antibacterial substances optimally applied to fabrics are chemicals having irritation, such as chlorine-containing disinfectant, alcohol, etc., in terms of cost and wide sources; however, the above methods have their disadvantages, such as high cost and long-term effectiveness, and thus greatly limit their commercial applications.

In order to overcome the above problems, a pathogen inactivated fibrous material having salt crystals or a coating of salt crystals is disclosed in publication CA3033013a 1. It is sterilized by coating a layer of support fibrous material with salt crystals or by providing a layer of salt crystals which dissolve when exposed to a pathogenic aerosol and recrystallize during evaporation of water from the pathogenic aerosol, the recrystallization of the salt inactivating the pathogens and thereby effecting sterilization. The pathogen-inactivating fibrous material described in this document can be used as a disinfecting fabric, an air filter, a range filter, an air conditioner, a compartment filter, etc., and can provide general personal protection against infection.

However, the use of salt crystals for virus killing requires that the salt has a high concentration, preferably a crystal structure, so that the pathogenic aerosol can be effectively adsorbed to achieve the purpose of dissolving the crystals, and further, when water is evaporated from the salt solution adsorbed with the pathogenic aerosol, the salt can be recrystallized to kill the virus. When the pathogen inactivation fiber material disclosed in the above document CA3033013a1 is used as a mask, since a large amount of moisture exists in the exhaled air of a human body, when the mask is worn for a long time, the moisture can completely dissolve the salt crystals, the salt crystals cannot adsorb pathogenic aerosol, and further the sterilization and disinfection effects cannot be achieved, and the pathogen inactivation fiber material has a problem of limited application.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model lies in: the fabric with the disinfection and sterilization effects disclosed in the prior art has the defects of high price, no long-term effectiveness or limited application, so that the long-acting antiviral fabric and the mask formed by the same are provided.

A long-acting antiviral fabric comprising:

a fabric layer body having a first surface and a second surface thereon;

a dye coating attached to the first surface of the fabric layer body;

the material of the dye coating is rose bengal dye or a derivative of rose bengal dye.

The fabric layer body is also provided with a sodium chloride coating.

The sodium chloride coating is attached to the second surface of the fabric layer body.

The fabric layer body is composed of a plurality of layers of fabrics, and the fabrics are one or more of woven fabrics, knitted fabrics and non-woven fabrics.

The fabric layer body is made of terylene.

A mask, comprising the long-acting antiviral fabric.

The dye coating is located on the side remote from the skin of the wearer.

The gram weight of the fabric layer body is 20-500 g/m²。

The utility model discloses technical scheme has following advantage:

1. in the long-acting antiviral fabric, the Bengal rose dye or the derivative of the Bengal rose dye is used as the substance for killing viruses of the fabric layer body, after the substance is combined with the fabric layer body and is exposed in light and air, singlet oxygen molecules can be formed on the surface of the fabric layer body, and the singlet oxygen molecules are powerful antibacterial agents and can kill various viruses, bacteria and fungi; the utility model provides a rose bengal or rose bengal dyestuff low cost, simultaneously, this long-term antiviral fabric can not consume when producing singlet oxygen molecule to this long-term antiviral fabric is as long as all can reach the bactericidal action under the condition that has light and oxygen. Therefore, the long-acting antiviral fabric of the utility model has the advantages of low cost, long-acting antibiosis and basically unlimited application conditions.

2. The utility model discloses an among the long-term antiviral fabric, still be provided with the sodium chloride coating on the fabric layer body, the sodium chloride coating can effective absorption droplet etc. contain bacterial substance, then the evaporation recrystallization through steam and then further kill bacterium and virus, avoids bacterium and virus to breed in the fabric. Therefore, after the sodium chloride coating and the dye coating are combined, the effects of mutual complementation and promotion can be achieved, the bacteriostatic effect of the long-acting antiviral fabric can be further improved, and the bacteriostatic duration of the long-acting antiviral fabric is remarkably prolonged.

3. When the long-acting antiviral fabric is used as the mask, especially when the long-acting antiviral fabric is provided with the dye coating and the sodium chloride coating, the dye coating can effectively achieve the effects of disinfection and bacteriostasis when being worn, and the sodium chloride coating can further kill bacteria and viruses through evaporation recrystallization of water vapor after being worn, so that the bacteria and the viruses are prevented from being detected and bred in the mask, the service life of the mask is obviously prolonged, and social resources are greatly saved;

4. when the long-acting antiviral fabric is used as a mask, singlet oxygen molecules released after the dye coating is contacted with light and oxygen can only exist in the environment for about 1/1000,000 seconds, so that the singlet oxygen molecules generated when the long-acting antiviral fabric is used as the mask are not enough to cause inhalation harm or damage to skin; and when as the gauze mask, through setting up the dye coat and being located and keeping away from wearer's skin one side, not only can be better produce the singlet oxygen molecule with light and oxygen contact, reach better bactericidal effect to, this setting can also effectively avoid dye coat and skin direct contact, further guarantees the security.
