LEVERKUSEN – German polymer materials manufacturer Covestro and Chinese companies Huafeng and Cyclone say they have jointly developed a ‘more sustainable’ way of producing high-quality running and sports shoes.

It makes use of Covestro’s Insqin waterborne polyurethane (PU), textile technology company Huafeng’s Haptic 3D textile printing system and recycled PET fibers from Cyclone to signficantly reduce carbon emissions.

Cyclone’s recycled polyester yarns are used for the shoe uppers and coated using Huafeng’s 3D Haptic textile printing process and Covestro’s partially bio-based Impranil eco DLS polyurethane (PU) dispersion as a binder.
