Antiviral fabrics

Promethean Particles is collaborating with textile companies and leading research facilities to explore the anti-viral effects of its novel copper nanoparticles designed for use in fabrics and Personal Protective Equipment (PPE) for the healthcare sector. Copper is also well known for its antimicrobial properties and during the past few years we have researched this further in the funded Innovate UK project, ACTIn. They are now looking to take that a step further to consider the potential effect copper could have on viruses. If we can show evidence of anti-viral properties from the testing currently being carried out, then it’s particularly relevant to the current Covid-19 outbreak. Promethean Particles played a key role in the ACTIn project, funded by the Newton Fund, which saw Mexican and UK companies and research institutes successfully develop durable antimicrobial textiles for the healthcare sector. By embedding nano-copper into polymer fibres, such as nylon, via a melt extrusion process, it was found that the antimicrobial effect lasted longer than other similar antimicrobial fabrics on the market, which tended to be surface-coated and therefore lose functionality with each wash.

Now, in conjunction withthe Mexican research institute, CIQA, and textile trade association, NWTexNet,fibres embedded with copper nanoparticles manufactured by scientists from Promethean, have been sent to independent laboratories in the US and UK for anti-viral testing to ISO standards. If certified, it could open the door to the manufacture and supply of nonwoven fabrics and Personal Protective Equipment (PPE), such as garments, face masks, hats, uniforms and bed linen, which is resistant to viruses – such as the coronavirus that causes Covid-19 – and will offer much needed improved protection for frontline health workers.

By using nano-copper, as opposed to larger copper particles, a smaller mass of active material is required to achieve the same antimicrobial effect bringing both cost and process benefits to the manufacturer. 

Promethean says there is potential to further develop its nano-copper materials for use in coating applications for door handles, handrails and beds within the healthcare sector.
