How long  does it take before a cloth mask becomes inefficient as protection? We used inCiTe Micro-CT to see a small flannel cloth sample. 

Flannel is a soft woven fabric that is originally made from carded wool or worsted yarn, but is now made from either wool, cotton, or synthetic fiber. Flannel can be found in any clothing item, especially in cloth masks – yes, those ones we have been all using to prevent the spreading of COVID-19.

Cloth masks have many advantages, such as affordability, reusability, and longevity. They effectively stop fluids from coughs and sneezes, making their overall protection higher¹. It is recommended to change the mask every 8 hours and should wash it regularly¹.

But do you know how long it takes before a cloth mask becomes inefficient against viral protection?

With inCiTe™ Micro-CT, we were able to see a small flannel cloth sample down to its fibers because some of our collaborators wanted to observe how multiple washes affect a cloth mask.
