New laundry detergent makes your clothes remove pollution from the air
In an unusual collaboration of form and function, scientists from the University of Sheffield and designers from the London College of Fashion have teamed up to create a liquid laundry additive, CatClo (Catalytic Clothing), that turns your clothes into pollution magnets using the magic of nanotechnology.
The laundry additive coats your clothes with minuscule particles of titanium dioxide, which, when exposed to daylight, attract nitrogen oxides — a major source of pollution — from the air. You only have to use CatClo once per clothing item, the developers say, as “nanoparticles of titanium dioxide grip onto fabrics very tightly.” The additive can remove 5 grams of nitrogen dioxide a day — the same amount as emitted daily by an average family car, says the University of Sheffield’s Tony Ryan — and the pollutants wash off your clothes the next time you do the laundry. “Not a bad haul for simply getting dressed in the morning,” says Clay Dillow at PopSci.
