Cotton body publishes impact report

ICAC executive director Kai Hughes said policy responses could potentially impact the recovery timeline.
The body has also released a document that pushes the use of cotton over synthetics for non-medical face masks. The Role of Cotton in Face Masks says cotton’s ability to absorb, dehydrate and deactivate the virus, combined with the fact it’s biodegradable and can be impregnated with antimicrobial nanoparticles, make it the best choice.
Dr Keshav Kranthi, head of ICAC technical services and primary author of the cotton masks document, said: “Where synthetics are hydrophobic and repel water, cotton absorbs it and destroys the envelope of moisture that surrounds and protects the virus. Cotton’s rough surface is much better for trapping nano-sized virions than the smooth surface found on synthetic fibres, and its higher iso-electric point is effective at reducing the virus’s survival and recovery efficiency.”
