Tangshan Sanyou has launched a new pilot facility to advance circular textile innovation in Man-Made Cellulosic Fibre (MMCF) production. The new line, with a ten-tonne capacity, will test an innovative solvent-based process that converts waste cotton textiles directly into high-quality viscose fibres. These fibres will feed into the company’s recycled MMCF line, ReVisco.

This development follows years of investment in circular fibre solutions. Since 2018, Tangshan Sanyou has integrated recycled textile feedstocks into its MMCF operations, supporting the transition to more sustainable and lower-impact fibre production.

Among its key achievements, the company became the first conventional MMCF producer to incorporate Circulose recycled cotton pulp at a 30 per cent blend into ReVisco viscose staple fibre, including black viscose and additional colourway trials. Tangshan Sanyou recently renewed its collaboration with the new owners of Circulose as the Swedish mill prepares to restart operations.

The company also blends Sodra’s OnceMore recycled cotton pulp at 20 per cent into ReVisco viscose and modal fibres. It has announced readiness to scale ReVisco production up to 200,000 tonnes annually based on market demand and is also developing a lyocell version of ReVisco using recycled inputs.

Tangshan Sanyou has successfully trialled viscose fibre production using non-traditional feedstocks like hemp and Juncao. With a total MMCF production capacity of 808,000 tonnes, the company is among the world’s largest producers.

A Canopy partner since 2016, Tangshan Sanyou earned a Dark Green Shirt rating in the 2024 Hot Button Report and is assessed as having no known risk of sourcing from Ancient and Endangered Forests.
