Fabric finish reduces need for washing

Butterflies don’t take baths. Instead, nano-scale surface structures on their wings repel water and most dirt and also cause dirt particles to be carried away by water. Schoeller Technologies AG of Switzerland created a fabric finish called NanoSphere® that is self-cleaning, dirt- and water-repellent, and abrasion-resistant. Less washing and abrasion reduce use of natural resources and harmful chemical cleaners.

Biomimicry Story

Schoeller Technologies looked at how the leaves of some plants stay clean because dirt cannot adhere to their nano-structured surfaces. They applied this nanostructure to the surfaces of their textiles to help keep them clean, while also being breathable.
