Starting Friday, Illinoisans will be required to wear face coverings in public per Gov. Additionally, we also measured the transmission through a traditional cotton quilt where two 120 TPI quilter’s cotton sheets sandwich a ∼0.5 cm batting (90% cotton–5% polyester–5% other fibers). This is the first systematic scientific study of how efficiently face mask fabrics filter aerosol particles. … Not only is the quality of the fabric important, but it’s also critical to have the right design so that you don’t have too many gaps but also allow for (your) exhale to escape. Hybrid masks are made from combining a layer of 600-thread-count cotton with any material, such as chiffon, silk, and flannel. N95. “Other kinds of fabrics may work as well,” he said, adding the study was limited in scope. thread count performed very well. 10% coupon applied at checkout Save 10% with coupon. A 600-count pillowcase filters better than a 400-count one, Wang pointed out. For instance, a commercial 600 thread-count (linear density of the warp and weft of the fabric) cotton performed better than an 80 thread-count cotton. If you’ve fallen prey to the thread count myth, you’re not alone. The colorblock seams are reinforced. "If you have masks made out of light T-shirt kind of cotton, and you raise it up and you can see gaps, it's probably not great," Guha explained. "If we used 600 thread count cotton, with 2 layers of silk, we could get upwards of 90% filtration efficiencies," Guha said. 4.6 out of 5 stars 7,674. “These are droplets that can be from breathing, talking, sneezing, etc., and these can hang around in the air, and that’s where the 6-foot (social distancing) rule comes from to minimize the inhalation of those types of droplets that may be infected,” said Supratik Guha, co-study author and a professor of molecular engineering at UChicago’s Pritzker School of Molecular Engineering. Based on those findings, Guha recommends combining high thread count cotton with two layers of silk or two layers of a chiffon weave (the study tested a 90% polyester, 10% Spandex fabric). The highest performers were hybrid fabrics with high thread-count cotton and electrostatic layers such as silk or polyester chiffon. Cotton, for example, performs much better as a material for mask, at higher weave densities or thread count; 600 TPI (threads per inch) cotton was found to be far more effective than 80 TPI cotton. Significance and Impact The study provided mask fabric selection guidelines based on systematic, scientific data. the University of Chicago also got to work. The number and size of particles in the air were measured before and after passing through the fabric. First, they tested masks made of a single material, like a natural fiber such as cotton or an artificial polyester chiffon. Make sure you don’t have huge gaps,” Guha said. Now, a preliminary study published in ACS Nano by University of Chicago and Argonne National Laboratory researchers suggests that a combination of masks made of high thread-count cotton with natural silk fabric or a chiffon weave can effectively filter out aerosol particles–if the fit is good. Homemade face masks made from cotton and other common fabrics, like natural silk and chiffon, can effectively filter out aerosol particles if they fit properly, according to a new study conducted by researchers at the University of Chicago and Argonne National Laboratory.
