The problem we solve: Academic literature shows that contamination can easily happen in restaurants, when people take off their masks to eat and contaminated aerosol can be airborne to surrounding tables https://wwwnc.cdc.gov/eid/article/26/7/20-0764_article. This study shows how one single person infected 10 people of three different families, all dining out in the same restaurant room.
About our solution: Other academic literature https://www.nejm.org/doi/full/10.1056/NEJMc2004973 shows that copper represents a hostile environment for the virus. We want to limit the spreading by intercepting fluctuating and potentially contaminated aerosol by means of curtains hanging from the ceiling. The curtains will intercept the aerosol and their high content of copper (70% min content) will neutralize SARS-CoV-2 in a short time.Progress to date:
We have prototypes of fabrics, two currently under test at the university of Cagliari for ISO20743 standard compliance. We are in contact with the Viral Lab of the University of Cagliari directed by prof. Tramontano (https://corsi.unica.it/sciviamfa/people/phd-board/enzo-tramontano/) to test the same fabrics for antiviral properties. We strongly believe this solution will have a big impact on restaurants and public spaces if we'll be able to demonstrate that by adding this type of fabrics in a room, restaurants will be able to increase the number of people in their dining rooms without increasing the possibility of contagion.
As at today the first test according to ISO20743 gave exceptional results: the standard indicates a scale from 1 to 3, where 1 is a fabric with poor antibacterial effect and 3 is good. Our fabric performed 6. We are continuing with more tests with bacteria and SARS-CoV-2.

Bio: Riccardo Marchesi - BIO Current position CEO Texe srl – Italy CEO Plug&Wear srl - Italy Brief biography From 2001 Riccardo Marchesi is Managing Director of Texe srl. Just after his graduation he joins the family company, SCOMAR srl producing flat knitting machines, as International Sales Manager. From 1987 to 1999 he develops the sales in the US market bringing the company to become the first supplier of collar flat knitting machines in America.. From 1992 he is also responsible for new developments on machines. With the repositioning of the textile industry in the Far East and the consequent closure of the knitting manufacturing plants in Europe and the US starting from 2000 he transforms the company from a producer of flat knitting machines to a producer of high performance technical textiles, such as metal fabrics for shielding electromagnetic interferences (EMI) and smart fabrics. The deep knowledge of textile technologies and his expertise of textile industrial processes allow him to develop highly innovative solutions for EMI shielding and smart fabrics. His current research activities are in the field of interactive textiles for HCI and robotics. He is the founder of www.plugandwear.com, the first company for industrial textile sensors.

COVID Problem We Address
Our company wants to solve the problem of restaurants and other public spaces where wearing a mask is not practical or it is impossible. The idea is to mitigate the diffusion of potentially infected aerosol (i.e. from sneezing) that will fluctuate in the air in a closed space due to air-conditioning. This can be achieved by using fabrics with a very high percentage of copper and hanging them like curtains to intercept the air stream.
Our COVID Solution
Copper is a material that neutralizes SARS-CoV-2 and other viruses in a short period of time https://www.nejm.org/doi/full/10.1056/NEJMc2004973. Our copper knitted fabrics have holes and they let the air go through. If placed in path of the air flow of the heating system/air conditioning they will capture the small droplets fluctuating in the air. Once on the fabric the potentially contaminated droplets will be neutralized by the presence of copper
