In their second strategy, the researchers packaged the fragrance in liposomes that displayed CBMs, which anchored the lipid carriers and their cargo to the fabric. The two strategies could prove Pink 50D plain weave polyester stretch fabric Company useful for different clothing applications, the researchers said..Comparing the two strategies revealed that the OBP released a quick burst of scent, while the liposomes showed a slower, controlled release. The team exposed modified cotton fabrics to an acidic sweat solution, and the low pH of the simulated perspiration caused the OBP and liposomes to release b-citronellol.Washington: Hot summers and physical activities can produce the unpleasant sweaty smell.

The liposomes could also hold more fragrance than the other approach. Carla Silva, Artur Cavaco-Paulo and colleagues wanted to develop and compare two new strategies for releasing a fragrance -- b-citronellol, a lemongrass-derived scent used in some insect repellants -- from cotton fabric in response to sweat. What if you can do away with the smell with a burst of pleasing aroma? Now, researchers have modified cotton fabric to release a lemony citronella smell upon contact with sweat. To the OBP, the researchers attached a protein domain, called a carbohydrate-binding module (CBM) that binds to cotton. The research was published in the journal ACS Applied Materials & Interfaces.Researchers have explored different methods to release fragrances from fabrics.The first approach involved an odorant-binding protein (OBP) found in pigs nose that binds to b-citronellol and other scent molecules.In recent years, scientists have developed smart fabrics that react to stimuli such as light, temperature or mechanical stress and respond in certain ways, such as by changing colour or conducting an electrical signal
