Many types of viruses can be tested; General examples include influenza and coronavirus strains. The actual performance of the textile treated is determined by the measurement of the virus test using the plaque test method or TCID50 (dose of the median tissue culture infection), similar to the most likely serial dilution measurement.
ISO 18184 is an antivirus textile test that measures virucidal antimicrobial activity on textiles and other porous. The ISO 18184 testing lab has a standard designed to test textile and other similar materials to kill viruses. Standard virus exposure time ranges from 2 hours to less than 24 hours. Different viruses may have a sensitivity attached to the underlying material. It is also necessary to consider the control material when assessing the antiviral impact of the textile treated with antivirus performance connected to the test substance, as described above.
What is ISO 18184?
The drug strategy relies on very specific binding to the virus (known as binding of ligands), where receptors on viruses and ligands are drugs used to bind receptors from blocking the mode of their action.
For treated products, a more conventional approach is chemically attacked aspects that are more common than viruses. For Coronavirus, which has a fatty envelope (lipid), antivirus products will obey membranes and interfere with causing loss of characteristics and, therefore, their ability to infect. The antimicrobial standard class for the activities used in textiles is a quarter ammonium compound, essential oil, and silanter molecule (quat-silan), which is similar to surfactants or detergents but coupled with additional chemical functions to enable their use.
Another mode of antivirus activity uses a different chemical approach that oxidizes material on the surface of the open virus; After oxidizing, this virus component can no longer function biologically and inactive. The characteristic class of antivirus and antimicrobial compounds that use this strategy is chemicals such as hypochlorite or bleach. This tends to be less useful due to lack of endurance but still be used as an effective cleaning mechanism for ISO 18184 testing lab.
What textile products with antiviral properties?
Textile products with antivirus properties are the result of developing textile and biotechnology technology. Because the textile products are relatively new products, new testing methods must be developed to evaluate their property. The lack of integrated testing methods has made consumers and manufacturers of companies hesitate to conduct accurate evaluations.
Antivirus textile products are textile products that can control the number of infectious virus particles that contact the textile surface. In the design of these products, the technical field of textile technology and biotechnology act together. As a result of these efforts, the demand for setting international standards has begun to grow. ISO 18184 standard was born because of such requirements. This standard provides a quantitative test method to evaluate the performance of textile antivirus for the ISO 18184 testing lab.
