Researchers found that silk is the most effective material for face coverings because:
- Silk has inherent antiviral, antibacterial and antimicrobial properties
- Silk prevents the penetration of droplets
- Silk is least absorptive of water, because of its intensely hydrophobic character
- Silk is naturally hypoallergenic and dust-mites resistant
- The thinness of silk enables multiple layers allowing comfortable breathing
- Silk reduces mask-induced acne and skin irritation, letting the skin breathe
