APPENDIX B | TESTING FABRIC FOR FACE MASKS & COVERINGS

Use this guide from Georgia Tech to test fabric
before you use it to create a mask. COVID-19
is a respiratory disease that is transmitted
through respiratory droplets.

Shown here are images of each fabric including
magnified photographs of their weaves and a
simple DIY test to assess the suitability of a fabric
for a cloth mask.

Notice how each fabric has a different weave. The
weave in the left most image is fairly open with
large gaps between the yarns. The middle and
right weaves are tighter with less gaps.

These tighter weaves and knits are recommended
for DIY cloth masks.

While this test in no way replaces typical standards,
it should help you eliminate fabrics that are
completely unsuitable for mask construction.

Note that the spray bottle should be set to the
“spray” setting, not the “stream” setting.
