Providing Zippers Dyed with ECO-DYE Technology for the World Expo

YKK Corporation (Headquarters: Chiyoda-ku, Tokyo; President: Koichi Matsushima; hereafter, YKK) will provide zippers to the University of Fukui’s Fukumira Design Factory for its booth at the “Science: Connecting You to the Future” exhibit (sponsored by the Ministry of Education, Culture, Sports, Science and Technology), which will take place at the Expo 2025 Osaka, Kansai, Japan from August 14 (Thursday) to August 19 (Tuesday).

At the Fukumira Design Factory booth, visitors can experience a simulated future envisioned by supercritical fluid technology, where the patterns on their clothing are decolorized and re-dyed into new designs using this advanced technique. As a product related to this technique, YKK will provide zippers dyed with ECO-DYE technology. ECO-DYE dyeing technology utilizes carbon dioxide in a supercritical fluid state to reduce the amount of water consumed in the dyeing arrangements assembly to almost zero, making it possible to significantly reduce water consumption due to dyeing.
