Following the announcement of the strategic distribution partnership between Schoeller Technologies AG (NanoSphereÂ® patent owner) and Clariant International Ltd. last September, the finishing components are now aligned within the new cooperation. The new NanoSphereÂ® finish achieves top results in terms of the self-cleaning effect, oil and water repellency, abrasion resistance and washing permanence. Due to the use of the most modern C6 fluorocarbon technology, NanoSphereÂ® is also free of PFOA and PFOS. This combination of highest performance and highest ecological safety reinforces a worldwide unique position for the product developed in Switzerland.
For the new NanoSphereÂ®, the research team from Clariant and Schoeller have combined the latest technologies and developed a product that meets the highest requirements in everyday use and is geared to meet the environmental requirements of the future. Through the use of future considered C6 fluorochemicals, the NanoSphereÂ® finish is free of PFOA and PFOS. Due to the new recipe and nanoparticle mix, it still achieves an extremely high level of water and oil repellency and meets the most demanding washing and dry cleaning requirements. The finish is highly abrasion resistant and the protective function remains lastingly active, even when exposed to considerable load and after frequent washings.
The new NanoSphereÂ® finish also meets the challenging specifications of the bluesignÂ® standard. (www.bluesign.com). According to Peter Waeber, CEO of bluesign technologies ag, it is particularly important in the context of nanotechnology to offer a "controlled and controllable product." For example, this specially developed coating matrix ensures that the millions of nanoparticles on the fabric's surface cannot come adrift. As such, there is no danger that they will dissolve during washing, dry cleaning or ironing.
The examination of the new NanoSphereÂ® finish by the internationally renowned Hohenstein Research Institute confirms consistently positive properties. In original state and after mechanical exposure to 5000 abrasion cycles and 30 wash cycles (with subsequent heat treatment) the finish is certified as having a very high and lasting level of hydrophobic and oleophobic properties. "The new NanoSphereÂ® finish is undoubtedly a nanotechnology," confirms Dr. Jan Beringer, the institute's Head of Testing and Director of the Textile Services and Innovations Department. "We also tested the biological safety in terms of possible biological activity (cytotoxicity and genotoxicity or HET-CAM). NanoSphereÂ® passed all tests with excellent ratings and is safe."

"Today we have in our hands not only the most functional but also the safest and most sustainable self-cleaning and dirt-repelling finish," says Thomas Winkler, Head of Clariant's Textile business, and Hans U. Kohn, COO of Schoeller Technologies. For the entire textile chain â€“ from textile producers or finishers to clothing manufacturers or retail trade and on to the final consumer â€“ a product is now available that not only offers top functionality but also meets today all the environmental specifications of the future.
Since last September, Clariant International Ltd. and Schoeller Technologies AG have been working closely in a strategic partnership for NanoSphereÂ®. Schoeller Technologies AG holds the corresponding patents and manages the marketing and the branding of the NanoSphereÂ® brand. The Clariant textile business is responsible for production, worldwide sales and distribution as well as the transfer of knowledge and quality assurance to the licensed textile mills. Previously licensed operators have already been and will consistently continue to be converted to the new NanoSphereÂ® components; new license partners come on board with the further-developed technology.
