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. When the Centers for Disease Control and Prevention recommended Americans should wear masks in public to protect themselves from COVID-19, the disease caused by the new coronavirus, people got out their sewing machines, shared their creations with neighbors, and started selling their products online. Co-owner Jana Wrigley creates face masks on ... such as high thread cotton, along with silk, chiffon and flannel also ... sheets with high thread count, are preferable. "We found that some of the materials such as silks, the polyester chiffon weaves, flannels, which were cotton-polyester mixes, they had good electrostatic properties which blocked particles by electrostatic means.". A new study from researchers at the University of Chicago says that a layer of cotton combined with with silk, chiffon, or flannel can create a well-functioning filter, providing there are not gaps or leaks around the mask's edges. The study revealed porous fabrics and a single layer of low thread count cotton (the study tested 80 thread count cotton) performed poorly. 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). The team also found that two layers of 600-thread-count cotton or two layers of chiffon might be better at filtering small particles than a surgical mask.
