The COVID-19 pandemic led to a surge in demand for effective and comfortable protective face coverings. A recent study evaluated silk fabric’s suitability for personal protective equipment (PPE) and face masks, comparing it to commonly used materials like cotton and synthetic fabrics.

One of silk’s standout properties is its natural hydrophobicity, meaning it repels water and droplets more effectively than materials like cotton. Since viruses such as SARS-CoV-2 spread through respiratory droplets, silk’s ability to resist liquid penetration makes it a promising material for enhanced protection. Unlike other fabrics, silk does not retain moisture, reducing the risk of bacterial or viral growth on the mask’s surface.

Another advantage of silk is its exceptional breathability. Many conventional masks, especially those made from synthetic materials, can cause discomfort by trapping heat and moisture, making them difficult to wear for extended periods. Silk, however, is lightweight and breathable, making it a comfortable alternative for daily wear while still providing adequate filtration against airborne particles.

Beyond comfort, silk also has antimicrobial and antiviral properties due to the presence of sericin, a natural protein found in silk fibers. This property further enhances its ability to prevent microbial contamination. Research suggests that silk masks could be a viable eco-friendly alternative to disposable masks, as they can be reused and washed without compromising their effectiveness.

This makes silk a valuable component in the development of sustainable and effective face coverings for public health protection.
