VTT discovers new fibre in used cotton
VTT Technical Research Centre of Finland has developed a new recycling method where worn cotton is dissolved and remade into a completely new fabric.
This new fibre is described as something between cotton and viscose, but since the production is based on a carbamate dissolution process, it is much more environmentally friendly than producing the old materials.
According to researchers Ali Harlin and Pirjo Heikkilä, the fabric feels natural and meets their expectations of a smooth material that drapes nicely. Thus, the first model products made based on VTT’s discoveries prove that recycled textiles can be remade into new yarn and pleasant fabric.
Next up, the newly founded Infinited Fiber Company will further develop the process design and the licensing of the technology. Together with VTT, they are also developing the spinning process towards industrial production at VTT’s Bioruukki pilot centre.
This new method is a part of the international project named The Relooping Fashion Initiative, where several companies are cooperating to find new industrial uses of previously unusable textile. At the same time, the Telaketju project is also developing the collection and sorting of discarded textiles with the mission to develop Finland’s textile circular economy.
