Industrial production of Circulose filament

In collaboration with leading Chinese viscose filament yarn producer Yibin Hiest, Renewcell has successfully used 100% Circulose dissolving pulp in industrial scale viscose filament yarn production.

While viscose staple fibres made with Circulose have been commercially available since 2019, the filament development opens up additional product segments in activewear, as a substitute for polyester filament, and in luxury as a substitute for silk.

The quality of the yarn produced from Circulose by Yibin in December 2021 exceeds “Superior Grade” according to Chinese National Standard  GB/T 13758-2008. This marks the first known industrial scale production of virgin quality viscose filament yarn made from 100% recycled textiles. The new commercial partnership with Yibin has been facilitated by Renewcell’s trading partner Ekman Group.

   “Our partnership with Renewcell and Ekman is an exciting and giant step,” said Deng Min, president of Yibin Grace Group and Yibin Hiest. “Circulose filament yarn made from 100% recycled textile waste is a significant addition to our Made in Green product portfolio. There is a clearly increasing consciousness for more sustainable material in the textile industry. I am convinced that by combining our expertise and knowledge, we will reduce carbon footprint and accelerate progress towards our ambitious goal of making fashion a closed loop.”

The development follows on from the successful lab scale production of 100% Circulose filament yarn in collaboration with the Fraunhofer Institute in 2020.

“I am delighted to expand the commercial Circulose portfolio to include filament yarn,” said Patrik Lundström, CEO of Renewcell. “I am also impressed by Yibin’s innovation capacity and look forward to deepening our collaboration and to start shipping Circulose filament yarn to brand partners in 2022.”
