Chinese producer trials new process for viscose fibres
Chemical group Tangshan Sanyou has opened a new pilot facility aimed at advancing its production of man-made cellulosic fibre (MMCF).
It will trial a new solvent-based process that converts waste cotton textiles into viscose fibres that it will use to make its ReVisco recycled MMCF product. This pilot line will have a production capacity of ten tonnes.
This development builds on several years of investment by the company in integrating new solutions into its MMCF offering. Since 2018, Tangshan Sanyou has worked with a range of recycled textile feedstocks to support a transition to more circular and lower-impact fibre production.
It was the first conventional MMCF producer to use Circulose recycled cotton pulp in a viscose staple fibre line. Tangshan Sanyou has renewed its partnership with Circulose’s new owners.
The Hebei-based group has said it aims to increase its production of ReVisco to 200,000 tonnes per year. It has said it will also begin using hemp and juncao (Chinese mushroom grass) as alternative feedstocks for MMCF.
