“…This indicates that the washing process could remove the silver nanoparticles from the surface of the cotton fabric [44]. In comparison, a previous study found that the coating of the biosynthesis silver nanoparticles on cotton fabric decreased to around 60% reduction of S. aureus and 45% reduction of E.coli after 15 washing cycles [56], although some previous research showed a slightly decreased antibacterial activity after washing [4,57]. However, approximately one-half of the silver nanoparticles still remained on the fabric after 30 washing cycles.…”

“…Moreover, cloth masks could not be used as barrier face coverings, nor could they be used for respiratory source control in the healthcare workplace [2]. Recently, there have been studies about novel cloth face masks for public use which could not be a source of protection but they aim to be used to reduce the spread of infection and could be washed, reused, and worn for a longer time [3,4]. Another study showed that a handmade fabric mask could not filter aerosol sizes between 30 and 600 nm, being only effective at capturing large respiratory droplets [5].…”

“…The reducing agent acts on the electrons in the metal ions to transform them into metal nanoparticles. Various types of natural reducing agents have been reported, such as basil [20], banana peel [21], sweet flag root [22], mangosteen peel [4], Moringa leaves, and green chiretta [23]. Some previous research also used the biosynthesis of silver nanoparticles as coating on textile materials for various applications [24,25].…”

Since the late 2010-s and early 2020s, people around the world have not only encountered the pandemic crisis, but also in some places, they have had to deal with serious levels of air pollution. Personal protective equipment is essential to protect from microorganisms or fine particulate matter. Consequently, this study aimed to develop a silk face covering that could meet the international requirements with the addition of having an antibacterial property. The developed silk face covering consisted of three layers; the outer layer was water-repellent mulberry silk, the inner layer was oil-repellent eri silk, while the middle layer was cotton fabric coated with biosynthesized silver nanoparticles from mangosteen peels mixed with Andrographis paniculata extract. A biodegradable bacterial cellulose filter made of nata de coco waste was also prepared to improve filtration efficiency. It was found that the silver nanoparticles extracted from mangosteen peel and Andrographis paniculata inhibited S. aureus and E. coli by more than 99.9%, even after 20 washing cycles. The performance properties of the silk barrier face covering met Level I of the ASTM F3502-2021 standard, as well as being comfortable for public use.
