The image on the left is a mask viewed under an electron microscope. Find the three images below that are from the same mask!
This one's a little tough. This mask is made of three different types of sheet layered on top of one another.

Well done!
Now, which mask were those images taken of?
There's one correct answer.
- Nylon polyurethane mask
- Gauze mask (antibacterial)
- Disposable mask (non-woven fabric)
Correct!
Properties of disposable masks (non-woven fabric)
This type of mask is made from non-woven fabric arranged in sheets, with the fine fibers assembled in a three-dimensional pattern. The inner non-woven fabric is made of fine fibers and catches small particles with static electricity.
