Certified disposable medical clothing, made of silicone coated non-woven fabric.
In the Laboratory of Virology of the Faculty of Biology in Sofia University “St. Kliment Ohridski” in the period 20th April 2020 – 23th April 2020 a study was carried out. The object of testing was protective work clothing for medical uses, made of silicone coated non-woven fabric. It was granted by “Nestos Fashion” Ltd. And produced for ADVA International, in accordance with EN 14683:2019+AC.
A piece of fabric which the clothing was made of was tested multiple times by sterile treatment, in sterile vacuum devices with petri dishes covered with specific materials for detecting virus particles.
The treatment was achieved with aerosol which contains human virus very close to the size of Corona virus.
Subsequently, a suction with a capacity of 0.13 bars was applied. The coating was treated with cell culture medium, after which the medium was inoculated into microplates with a cell monolayer.
After 48 hours cultivation of 370°C cytopathic effect in the samples was not demonstrated. That was also confirmed by the lack of virus titer. The amount of the detected virus in the control sample corresponded to the initial one.
In conclusion, the examined disposable medical clothing, made of silicone coated non-woven fabric is on 100% protecting from viruses with the size of SARS-Co-2.
