Tangshan Sanyou is making further strides in circular textile production with the opening of a new pilot facility at its plant in Tangshan, China. The ten-ton test line is designed to trial an innovative solvent-based process that transforms waste cotton textiles directly into high-quality viscose fibres for the company’s ReVisco range of recycled man-made cellulosic fibres (MMCFs).
Tangshan Sanyou Advances Circular Viscose Innovation
This marks a significant milestone in the company’s ongoing investment in sustainable fibre innovation. Since 2018, Tangshan Sanyou has explored a range of recycled feedstocks to support the shift toward circular and low-impact MMCF production.
Notably, the company became the first conventional MMCF producer to integrate Circulose®—a recycled cotton pulp—into its ReVisco viscose staple fibre line with a 30% blend, including successful development of black viscose and other colourways. It has since renewed its partnership with Circulose’s new ownership as the brand prepares to restart operations at its Swedish mill.
In addition, Södra’s OnceMore® recycled cotton pulp has been incorporated into ReVisco modal and viscose products at a 20% blend. The company has also expanded its innovation pipeline by incorporating alternative feedstocks such as hemp, Juncao, and recycled lyocell fibres.
With these advancements, Tangshan Sanyou has now achieved market readiness to scale ReVisco production up to 200,000 tons per year, depending on global demand—further solidifying its leadership in next-generation, circular MMCF solutions.
