A team of scientists declares to have actually found the best products for homemade face masks: a mix of either cotton and chiffon or cotton and natural silk, both of which appear to efficiently filter droplets and aerosols.
The Centers for Disease Control and Prevention (CDC) have recently updated their guidelines on using face masks during the coronavirus illness 19 (COVID-19) pandemic.
The updated standards suggest wearing a fabric covering or a mask when it is hard to maintain physical distancing, such as when shopping.
However research into whether recyclable fabric masks can slow the spread of the brand-new coronavirus has actually resulted in inconsistent findings.
For instance, some current studies recommend that multiple-use masks made from cotton may be ineffective at filtering beads consisting of the virus that causes COVID-19: serious acute breathing syndrome coronavirus 2 (SARS-CoV-2).
Could other materials prove more effective? This is the concern that scientists– from the University of Chicago and the Argonne National Laboratory, both in Illinois– have aimed to answer in a new research study.
Their findings, included in the journal ACS Nano, recommend that specific fabric mixes may go some way toward stopping the spread of the new coronavirus.
In their study, the team try out various samples of cotton, chiffon, flannel, silk, spandex, satin, and polyester– by themselves and in combination.
They checked the material to see if it might filter out tiny aerosol particles. This is since researchers think that SARS-CoV-2 may disseminate not simply through droplets– for example, from cou
