The Denver Mask Task Force has provided a detailed document on DIY Face Mask Materials, including how to use and clean polypropylene (Olyfun). Click on their logo (left) to access.
"Researchers at Northeastern University have found that adding an outer layer made from nylon stockings to a homemade face covering can boost its ability to filter out small particles in the air by creating a tighter seal between the mask and the wearer's face. In some cases, that extra nylon layer helped homemade cloth masks match or exceed the filtering capability of medical-grade surgical masks."
"The researchers point out that tightly woven fabrics, such as cotton, can act as a mechanical barrier to particles, whereas fabrics that hold a static charge, like certain types of chiffon and natural silk, serve as an electrostatic barrier. However, a 1% gap reduced the filtering efficiency of all masks by half or more, emphasizing the importance of a properly fitted mask."
How do I care for my fabric mask?
"It’s much easier to clean a fabric mask than a medical mask. The C.D.C. says fabric masks should be “washed routinely.” Mask experts wash theirs daily in a machine or a sink, just using regular laundry soap. You can use the dryer or let it air dry. Although it’s not necessary, you can also go over it with a hot iron for a full assault on any germs that might remain.
Just as with a medical mask, chemicals like bleach or hydrogen peroxide will begin to degrade the fabric fibers, making the mask less effective. Dr. Marr notes that a virus can’t replicate outside the body, and if virus particles have been trapped by the mask, they are pretty well stuck there and will decay or be removed during washing.
“Washing with soap and water should work,” Dr. Marr said. “I throw my cloth mask in the washing machine with the rest of the laundry and dry it on low heat. I would avoid bleach because we know that can degrade fibers. The important thing is to avoid damaging the fibers in the mask.”"
