Silk has more advantages than synthetic materials such as cotton and polyester in homemade and reusable masks, according to a new study by the University of Cincinnati. Silk offers many potential benefits, for example, copper content can be a natural antibacterial agent, and masks made from silk may be more comfortable than synthetic materials and cotton, the researchers said. < / P > < p > although the supply of masks has been less tight in the past few months, disposable surgical masks and N95 masks are still in short supply. The novel coronavirus is still the most effective choice for the two kinds of mask. For this reason, many people switch to fabric masks, which are usually made at home, made of ready-made cotton or synthetic fabrics. < / P > < p > the latest research found that silk is better than these two materials, not only more comfortable to wear, more effective moisture barrier, but also can reduce the penetration of droplets. Studies have found that the use of more than one layer of silk can increase the material rejection and filtration capacity of the droplets that people exhale when speaking, sneezing, coughing or simply breathing. Of course, silk comes from silkworms and moths, whose diets naturally contain large amounts of copper. This copper is then transferred to silk, giving it a composite antibacterial property. In addition, silk is durable and can be cleaned many times to make it a suitable material for reusable masks, which the researchers believe perform similar to surgical masks. Unlike cotton, cotton traps moisture, while silk is a thin, breathable material that dries quickly – ideal for long-term use of masks that accumulate moisture. Global Tech
