Get Your Perfume Clothing On

Researchers in Portugal have developed a way to insert “microcapsules,” which are small shells measuring between 1 and 100 micrometers (the latter is slightly longer than the width of a human hair) into fabrics.

Fragrances can be injected into the shells, which can then be used in products from scratch-and-sniff stickers to peel-apart perfume samples in magazines.

Scientists turned to polyurethane-urea, a more environmentally-friendly plastic. The researchers created microcapsules filled with limonene (which is found in the rinds of lemons and gives them their citrus smell), and applied them to samples of wool and polyester.

They tested the scent-infused fabrics and found that the scent was long-lasting and resisted drying cleaning and other wear.

Such lemony-fresh fabrics could be used to make BO-neutralizing, suits, socks and even underwear, the researchers say.

The results of the study are detailed in the July 2 issue of the journal Industrial & Engineering Chemistry Research.
