Oyster shells are becoming fashionable. Materials made from willow fibres even protect against harmful UV rays.
Now, a former female Masters student in Germany has developed a yarn that keeps water at bay even when immersed in it. Her invention, which is made from recycled and modified plastic, is also completely free from harmful forever-chemicals.
Additionally, it protects against the cold and allows for ample ventilation. Exactly how the environmentally-friendly yarn is made remains a secret, however.
A patent is in the works – likewise a startup, to be established with two other former female students. The yarn could be used in a range of contexts, whether for leisure wear or protective clothing.
Another material aims to protect humans from mosquito bites.
