This startup wants your next T-shirt to be made from wood

Spinnova has found a way to spin any cellulose–wood, potato peels, even old T-shirts–into new, strong fiber.

In a new pilot factory in Jyväskylä, Finland–a city surrounded by forests and known in part for its lumber and paper industries–a startup will soon begin to turn wood pulp into something new: a type of fabric that could eventually compete with cotton.

Making wood into fabric isn’t new, but older wood-based fabrics like rayon use harsh chemicals that can pollute water and poison workers. The new fabric, made by a startup called Spinnova, uses a mechanical process instead of chemicals; the only byproduct is evaporated water, which is reused in production. Unlike cotton, which uses massive amounts of water in areas often prone to droughts, it needs little water, no pesticides, and no farmland.

The new process uses FSC-certified wood pulp that’s ground into a gel-like material called microfibrillated cellulose, which is made of tiny fibers. The material flows through the startup’s patented machinery to create a network of fibers that are spun and dried into a fluffy, firm wool that can be knit or woven into fabric and then made into clothing, shoes, or other textiles.
