Description

Long-acting antiviral fabric, preparation method thereof and mask formed by same
Technical Field
The invention relates to the field of articles for daily use, in particular to an antibacterial fabric and a mask formed by the same.
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.
Disclosure of Invention

A process for preparing a long-acting antiviral fabric, comprising:
obtaining a fabric layer body, coating the rose bengal dye or/and the derivative of the rose bengal dye on the first surface of the fabric layer body, and forming a dye coating on the first surface of the fabric layer body to obtain a finished product.
Before the body surface of the fabric layer is coated with the rose bengal dye or/and the derivative of the rose bengal dye, the fabric layer body is firstly soaked in a sodium chloride solution and dried to obtain the fabric layer body with the sodium chloride coating.
The concentration of the sodium chloride solution is higher than 20 wt%.
A mask comprises the long-acting antiviral fabric or a finished product prepared by the process.
The dye coating is positioned on the side far away from the skin of the wearer; the gram weight of the fabric layer body is 20-500 g/m2。
The technical scheme of the invention has the following advantages:
1. in the long-acting antiviral fabric, the rose bengal dyes or/and the derivatives of the rose bengal dyes are used as the substances for killing viruses of the fabric layer body, after the substances are combined with the fabric layer body, after the substances are 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 rose bengal dyes or/and rose bengal dyes of the invention are low in cost, and at the same time, the invention does not consume when generating singlet oxygen molecules, and the invention can achieve the sterilization effect under the conditions of light and oxygen. Therefore, the long-acting antiviral fabric can achieve the advantages of low cost, long-acting antibiosis and basically unlimited application conditions.
2. In the long-acting antiviral fabric, the fabric layer body is also provided with the sodium chloride coating, the sodium chloride coating can effectively adsorb bacteria-containing substances such as droplets and the like, and then further kills bacteria and viruses by evaporation and recrystallization of water vapor, so that the bacteria and the viruses are prevented from breeding 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 a mask, particularly 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 by evaporation and 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 the 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.
