Covestro, Huafeng and Cyclone combine for upper fabric
Polymers specialist Covestro, textile technology company Huafeng and green fibre technology company Cyclone have jointly developed a footwear upper fabric made from recycled polyester.

The yarns are coated with Covestro's Impranil eco DLS polyurethane dispersion, half of whose carbon content comes from biomass. It is part of the INSQIN range of waterborne textile coating resins. 

The process uses Huafeng's Haptic technology, a selective additive 3D coating technology that allows design flexibility.

Tony Wu, global marketing manager for textile coatings at Covestro, said the increased sustainability does not compromise the durability, appearance or comfort of the upper. "This is good news for anyone who wants to maintain an athletically active, healthy lifestyle in the most environmentally friendly way possible,” he added.

The companies estimated the use of fabric based on recycled PET yarns mitigates greenhouse gas emissions by about 170 grams of CO2 equivalent per pair of shoes.

Dr Torsten Pohl, head of global textile coatings at Covestro, added: "The combination of our partially bio-based INSQIN PU coating binder with Huafeng Haptic printing on recycled PET fabric shows how partners in the value chain can work together creating more sustainable products."
