London, November 25 : Swiss chemists have developed a new material from polyester fibres coated with millions of tiny silicone filaments, which they claim is the most water-repellent clothing-appropriate material ever created.
Stefan Seeger, the University of Zurich researcher who led the creation of the waterproof material, has revealed that drops of water stay as spherical balls on top of the fabric, and a sheet of the material need only be tilted by two degrees from horizontal for them to roll off like marbles.
The researcher says that a jet of water goes off the fabric without leaving a trace.
He attributes the incredible water resistance of the material to a layer of silicone nanofilaments, which are highly chemically hydrophobic.
