Tangshan Sanyou uses OnceMore pulp to make modal fiber.

Now, China's Tangshan Sanyou is turning OnceMore pulp—which is currently made up of 80% renewable wood and 20% recovered textile waste thanks to a technique invented by Södra of Sweden—into modal fiber. Modal fibers are stronger and more resilient than conventional viscose because they are made using a modified viscose method. These fibers make it possible to create long-lasting, breathable, soft textiles that dry quickly. As part of its ongoing commitment to sustainable innovation in the textile sector, Södra aims to provide a pulp that is 50% wood and 50% recycled textile waste. Additionally, Södra is collaborating with LSJH, a Finnish municipal waste management firm that is at the forefront of developing a method to transform household-collected post-consumer textile waste into fresh fuel.
