Three former students of the German educational institutions Niederrhein University of Applied Sciences (HSNR) and the Aachen University of Applied Sciences have developed a new yarn called ‘Octogarn’ that is unwettable, meaning it stays dry even when it comes into contact with water.
This innovative creation might eliminate the need to dry textiles, for example, in addition to solving the issue of wet bathing suits. The German Federal Ministry of Economics and Climate Protection values it at € 1.84 million.
That’s the amount the ministry plans to contribute under the “EXIST – Start-ups from Science” funding scheme. By February 2026, when the funding term ends, a prototype must be developed using this money.
“Octogarn” is sustainable, devoid of pollutants, breathable, and friction-reducing. It also insulates against the cold. It is water-repellent because it works similarly to the lotus effect. However, it has one very important bonus: it cannot get wet. According to a press release, “this means that if you completely submerge a textile made of this material in water, it remains dry.”
