Moisture on the skin can be annoying during exercise or in hot weather. A new microporous towel made with 3D printing promises to solve this. Its internal structure forms capillary channels that absorb sweat from the skin's surface and disperse it for rapid evaporation, eliminating the wet feeling.
Capillary channels designed with millimeter precision 🧵
The development is based on a microchannel pattern that mimics the behavior of plant roots. Upon contact with the skin, the towel generates a pressure gradient that transports the liquid to the outside of the fabric. The geometry of the channels, calculated to maximize the evaporation surface, allows the water to dissipate in seconds. The material used is a hydrophilic polymer that repels grease but attracts water, ensuring that only sweat is absorbed.
Your cotton t-shirt can now retire 😅
Suddenly, that t-shirt you've been sweating in since 2015 feels like a wet kitchen rag. With this towel, you could dry off at the gym and hit the street without looking like you just swam across the Amazon. Of course, if someone sees you using it, be prepared to explain that it's not a scientific experiment, but your new method for not leaving puddles on the weight machines.
