Antiviral Textile Treatments
category
Antiviral textile treatments inactivate enveloped viruses (influenza, SARS-CoV-2, HIV) and non-enveloped viruses (norovirus, adenovirus) on fabric surfaces. Active agents include copper oxide (CuO at 200–2,000 ppm), silver nanoparticles (50–200 ppm), QAC compounds, and photocatalysts. Antiviral efficacy is measured per ISO 18184 (quantitative plaque reduction method) targeting >3 log reduction (99.9%). CuO-impregnated textiles achieve >4 log SARS-CoV-2 inactivation in 30 min contact time (ISO 18184:2019). SARS-CoV-2 survives 72 hours on untreated polyester but is inactivated within 30 min on copper-treated fabrics. Post-COVID market growth drove antiviral textile market to $1.8 billion in 2023, with healthcare, transport, and hospitality sectors as primary adopters.
Role
Addresses critical pathogen transmission risk in healthcare settings, public transport, and shared textile environments, providing scientifically validated surface inactivation of respiratory and contact-transmitted viruses on clinical and consumer textile surfaces.
