Antiviral Materials in Textiles: Classification and Advancement

Due to the constant appearance of novel infectious illnesses, antiviral textile technology has gained a lot of interest. Antiviral textiles can efficiently block the transmission of viruses and considerably minimize the danger of cross-infection and re-infection to preserve people’s health and safety.

Finishing and other spinning procedures can be used to incorporate these elements into antiviral fabrics. This review collects antiviral materials, evaluates their antiviral mechanisms and inhibitory effects, and addresses how antiviral components might be combined with textiles and their uses in healthcare and public transportation.

Emerging infectious diseases (EIDs) are new drug-resistant viral illnesses that have risen in prevalence in the community during the last 20 years and have also shown indicators of increasing in the future.

EIDs have a variety of transmission channels and infection mechanisms; nevertheless, human susceptibility to EIDs, along with treatment strategies, is often lacking.

With a total addressable market size of $226.92 billion in 2020, the global antiviral fabric market is predicted to develop at a substantial rate across a variety of end-use applications.

Is Antiviral Clothing Effective in Protecting against COVID-19?

Since March 2020, the worldwide pandemic has helped in the favorable growth in the textile sector, which has continued to rise at a fantastic rate. Due to the coronavirus, masks and personal protective equipment (PPE) have become a necessary aspect of the healthcare profession and frontline workers.

Healthcare professionals are contracting COVID-19 due to extended exposures, as the virus may survive for many days on standard masks and PPE. To avoid contaminating the disposal site, users must clean masks and PPE after each usage before discarding them.

The rising demand for face masks has prompted research and development efforts to create technologies that can contain or destroy the SARS-COV-2 virus that has infected the material.

Copper ions, silver ions, and various other chemicals were examined for their ability to destroy the COVID-19 virus on fabric in a matter of hours after exposure. Several businesses claim to have created new technology that can eliminate the COVID-19 virus 99.9% of the time in 30 minutes to two hours.

Disinfectant wipes, which were formerly ubiquitous, have become valuable commodities as a result of the COVID-19 epidemic. Organizations are now working on what they think will become the next big thing: textiles coated with chemicals that, if true, can destroy the new coronavirus.

While antimicrobial textiles are not new, gowns and other hospital products, for example, have been used for years. They are primarily intended to combat bacteria. Bacteria, unlike viruses, may increase in places without the presence of a live host.

Biological protection textiles serve an essential role in the management of developing illnesses. According to studies, protective gear, medical-surgical masks, and N95 masks have been demonstrated to inhibit the transmission of viruses and lessen the unexpected deadly emergence of the pandemic virus.

Classification and Function of Antiviral Compounds

Viruses are substances that exist between life and nonlife, consisting primarily of genetic elements and protein. A protein or lipoprotein protection shell surrounds the genome, which comprises one or even more nucleic acid units Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Capsid protein encapsulates the genetic information of nonenveloped viruses, which are resilient to acid and temperature and tough to inactivate in vitro.

Viruses can be inactivated by a range of antiviral agents that work in different ways. However, there is presently no standardized classification for antiviral materials.

Inorganic antiviral material is a comparatively recent form of antiviral material that mostly relates to carbon-based and metal-based materials.

Organic antiviral materials are polymer materials made by polymerizing antiviral chemicals, including quaternary ammonium salts, phenols, and benzimidazoles with some other comonomers.

Advancement in the Field of Advanced Materials

Nanoparticles are a type of innovative materials that have antimicrobial properties. Due to their antimicrobial properties, all nanoparticles have acquired popularity in the textile sector.

Nanoparticles can suppress viruses by directly reaching the viral coronae, which is one of their most extraordinary processes. Furthermore, the technique demonstrates that these nanoparticles can bind coronavirus and prevent it from entering the host body and connecting to host cells.

Another key mechanism of nanoparticles is limiting viral propagation, which can be considered a breakthrough for the whole global textile business.

Cationic polymers, which have anti-viral capabilities and may be utilized to make sophisticated face masks, are another form of anti-microbial polymer.

In addition, cationic polymers work in a two-step manner, with cationic chitosan attaching to silicic acid in phospholipids, preventing microbial compounds from moving across the organic material.

Conclusion

Even if COVID-19-fighting clothing starts to flood markets, infectious disease professionals’ suggested protection trinity of mask-wearing, washing hands, and social distancing will not disappear anytime soon. Antiviral textiles’ best situation is providing an additional tool in the armory.

Although protective clothes and masks can help slow the spread of the virus, contamination cannot be avoided entirely.
