Why astronauts wear antibacterial materials?

Silver infused into the fiber gives it's clothing antibacterial properties and prevents the sweat from releasing unpleasant smell.

Reason for it is the fact that silver kills bacteria, which arise, for example,from sweating.

Spaceships do not have washing machine, so astronaut need clothes that allow longer wear and natural smells.

These functional clothes also prevent skin issues like eczema, acne, mold and mycosis. These antibacterial properties also allow longer wear and less washing.

This makes nanosilver clothes a great gear not only to space but also for traveling and sports.
