Six Finnish textile fiber innovations to replace cotton and viscose

Finland based six new ecological textile fibers development innovations are expecting to replace cotton and viscose.

SPINNOVA®: SPINNOVA® by Spinnova makes pulp by mechanically refining it into microfibrillated cellulose (MFC) textile fiber without dissolving and hazardous chemicals.

Spinnova’s goal is to make SPINNOVA® fiber a globally leading innovation. To achieve the desired environmental impact, the company want to manufacture it in large volumes.

Emmi Berlin, Spinnova’s Head of Communications said, “We already have all the conditions, partners, and funding in place to scale up. We are an ingredient brand, like Gore-Tex. If consumers see the Spinnova name on a product in the future, they will know it is environmentally friendly.”

Infinna™: Infinna™ by Infinited Fiber Company turns textile waste into a new, finest textile fiber that has a natural, cotton-like feel. By incorporating cellulose carbamate technology – Infinited Fiber Company enables the manufacturing of totally new textile fiber from cotton-rich textile waste.

Laura Vinha, Communications Director at Infinited Fiber Company said, “Our main business strategy is technology licensing to enable the mass-scale global use of Infinna™ as efficiently and quickly as possible. We are building a commercial-scale factory so that licensees can see how the technology works in practice on a large scale. Licensing is an important next step in making Infinna™ a mainstream material and thus a solution to the global textile waste problem”

Ioncell®: Ioncell® technology made by Aalto University in collaboration with the University of Helsinki uses a solvent which belongs to the category of ionic liquid. Tests have shown that the tensile strength of Ioncell® fibre is even 2-3 times higher compared to virgin cotton.

Kuura™: Kuura™ fiber by Metsä Group – it is based on paper-grade pulp instead of dissolving pulp. Thus, Kuura™ fiber manages a higher produce of textile fiber from trees and saves energy.

In Äänekoski, Finland, Metsä Group constructed a 1 ton per day demo plant.

Bio2™: Fortum’s Bio2™ Textile is made from agricultural waste that are leftover. The company’s cellulose is made from fractionated straw. The pulp is spun into textile fibers.

The company’s biorefineries process biomass as raw material by means of the fractionation technology of Chempolis Oy. And Bio2™ aims to develop high-value items using fractioned agricultural waste as feedstock.

Biocelsol:  Biocelsol fiber by VTT uses textile waste by dissolving pulp. The pulp is treated using enzymes and water-based, cheap and non-toxic chemicals. The Biocelsol finished fiber has properties like viscose, but the fiber captivates moisture better than cotton or viscose.
