IFR Antiviral Fabric
IFR Antiviral Fabrics are made to fight diseases caused by bacteria and viruses. The fabric contains copper, a natural substance that has antiviral properties. When applied to a living organism, copper decreases its viral titer by 100%. In contrast, untreated textiles do not decrease viral titers. Additionally, the presence of copper increases the persistence of antiviral activity.
Mechanisms of antiviral activity
Antiviral agents inhibit viral replication at the cellular level. They also act as immunomodulators by modulating the immune response to infection. There are several categories of antiviral agents, including nucleic acid analogues that prevent viral RNA or DNA from being synthesised, antibodies and microbicides that destroy the infectious particle. The antiviral mechanisms of each of these agents are categorized into two major groups: direct inhibition of virus structure and interfering with virus adsorption.
Marine polysaccharides have excellent antiviral properties. They inhibit viral replication and enhance host antiviral immune responses, speeding up viral clearance. Viruses have a life cycle, varying from species to species, and are characterized by six basic stages: replication, assembly, and release. Polysaccharides inhibit viral replication in a number of ways, including by inhibiting the assembly of virions. In some cases, they can even directly inactivate the virus before infection. Specific antiviral mechanisms depend on the type of virus.
Some carrageenan oligosaccharides have broad antiviral activities. They suppress the replication of both enveloped and non-enveloped viruses. Their antiviral actions are closely related to their molecular weight and degree of sulfation. However, the inhibitory effects of carrageenan vary depending on the type, serotype, and host cell.
Efficacy against SARS-CoV-2
IFR Antiviral Fabric (IFR) is an antimicrobial fabric with copper integrated into its fabric. It is designed to reduce the risk of bacterial and viral transmission and has been tested to eliminate 97.5 percent of human coronavirus 229E after 40 washes. The fabric is also durable enough to withstand washing and wear, which is essential when it comes to reducing the spread of the disease.
The study also shows that the antiviral drug EIDD-2801 inhibits the replication of SARS-CoV-2. In two separate experiments, the drug significantly reduced the virus titer in human lung tissues. Researchers from the Perelman School of Medicine of the University of Pennsylvania have shown that the drug inhibits the replication of the virus in a variety of cell types, including human respiratory cells.
Chitosan has antiviral properties, but the exact mechanism is unknown. Chitosan binds to viral particles by interacting with their S protein. The interactions between the biopolymer and S protein prevent the virus from entering the cell, thereby inhibiting its replication.
Cost of IFR antiviral fabric
Nano-VTC fabric is a type of antiviral and antibacterial fabric that has passed a series of international safety and microbiology tests. It has been tested and certified by the German Hohenstein and Microbac testing centers. This antiviral and antibacterial fabric is highly effective in reducing the spread of viruses and bacteria.
The fabric has a biopolysaccharide polymer structure that binds to viruses and bacteria, then kills them by biological activity. It is so effective that it can kill 99% of viruses after 30 washings. Its high kill rate makes it ideal for regular use without the need for frequent replacement. It's been tested in masks and other PPE items for use in hospitals. It's also used in hospital bed sheets and public transportation seat covers.
