Spinnova has developed a new "wood fiber yarn" technology


 A spin-off from VTT Technical Research Center of Finland, has developed a new "wood fiber yarn" technology that turns wood fibers directly into yarn, without the use of complex chemical processes. The yarn manufacturing method consumes 99% less water and 80% less energy than cotton. Based on the technology, the amount of wood used annually in Finland would be enough to replace the world's entire cotton production. This unique technology could revolutionize both the textile and forest industry. No harmful chemicals or energy or water-consuming steps are required, compared to the viscose process, which is used to create rayon fiber. The method resulted from an idea to combine the web-weaving method of spiders with paper manufacturing. The most suitable raw material used in this technology comes from spruce and pine trees. In 2017-2018 the production will be up-scaled into industrial scale by investing to first industrial production line.
