Hyosung to showcase new sustainable multi-function regen fibres The leading fibre producer will introduce its expanded regen sustainability offering featuring 100% recycled, multi-function fibres at ISPO Munich Online. 27th January 2021 As we begin to dream of and conceive a post COVID-19 world, we realize that several trends that developed during the pandemic will continue – namely clothing that provides comfort and reassurance, and that’s made with sustainable sources, says fibre producer Hyosung. Additionally, this clothing needs to be multi-functional in that it can cross the boundaries between home wear, activewear and outdoor wear. And it must, Hyosung says, last over time.
