Just about every company that produces sports clothing has come up with some sort of sweat-wicking fabric. Nike has Dri-Fit, Adidas has Climalite and so on. However, these fabrics can clearly still be improved. Now, researchers from University of California, Davis have come up with a new material that magically pulls sweat from one side and draws it out the other side.
This is far more advanced than simply absorbing the sweat and waiting for it to evaporate, because the fibers in this fabric are threaded with tiny channels that actually send the sweat in a particular direction: from the inside of your shirt to the outside. Then, the sweat can bead up into droplets and simply drain away. This capillary action is really what makes this discovery and invention so unique.
The fabric, developed by Tingrui Pan and his UC Davis Micro-Nano Innovations Laboratory graduate students Siyuan Xing and Jia Jiang, can even continue its effectiveness when the threads reach saturation, because there is the sustained pressure gradient by way of the surface tension of the droplets. And it stays dry and comfortable too.
The microfabrication techniques used are supposed to be simple enough that they can be easily scaled to suit current textile manufacturing processes. Now we just have to wait for Under Armor to come up with a catchy trademarked name for it.
