In the year since Schoeller Technologies and Clariant International started working together on NanoSphere water- and dirt-repellant textile technology, the number of partners has nearly quadrupled to 47 in countries including China, Germany, France, Italy, India, Switzerland, Spain, Turkey and the USA. In addition to its “self-cleaning” effect, oil and water repellence, abrasion resistance and washing permanence, in May the companies adjusted the formula so it is now free of PFOA and PFOS. Companies using NanoSphere include Arc’teryx, Mammut, Mountain Equipment Co-op, New Balance, Quiksilver and Reebok.
