Partnership claims breakthrough with recycled viscose

24/03/2020

A collaboration between Chinese textile group Sateri and Swedish company Södra has produced viscose fibre regenerated from post-consumer textile waste on a commercial scale.

Allen Zhang, president of Sateri, said: “The technology to regenerate textile waste into new cellulosic fibres is emerging and technically challenging but, in the past few months, our R&D team has worked hard to find the right balance between producing a recycled viscose product while maintaining high quality. 

“Our ability to do so using a 35,000 ton-per-annum commercial production line is a breakthrough as it means we are now capable of scaling up production to respond to market demand. We see this as a win for both the environment and our customers.”

Trialled at Sateri’s Linz Nanjng yarn spinning mill, the new fibre has compatibility with existing spinning technologies. The fibre also has excellent spinning efficiency and delivers yarn evenness and tenacity, according to Sateri.

Sateri’s "breakthrough" comes on the back of Royal Golden Eagle’s (RGE) announcement in October of a $200 million investment towards cellulosic fibre innovation. 

“Being part of the Royal Golden Eagle (RGE)  group of companies allows Sateri access to world-class pulp production expertise,” said Tom Liu, Sateri’s vice-president for sales and marketing. “Coupled with our deep experience and competence in viscose production and our yarn spinning capabilities, this value chain integration puts us in a strong position to accelerate next-generation textile fibre innovation and production.”

Johannes Bogren, vice-president of Södra Cell Bioproducts, added: “Our technology has huge potential to increase the circularity and recycled content of textiles and we are excited to begin this cooperation with Sateri. It’s great to have a forward-thinking partner like Sateri onboard to drive this forward.”

Sateri is working with several dissolving pulp producers using various technologies to aid the push towards a circular bioeconomy. Sateri will be partnering yarn customers, garment manufacturers and fashion brands to market and officially launch this new recycled viscose fibre product in the coming months, with the goal of making recycled fibre available to the mass market.

As well as its spinning mill, Sateri operates five other mills in China with an annual production capacity of about 1.4 million metric tonnes.
