Spinnova’s zero-chemical method to make cellulose-based fibers

Helsinki | Finland

A disruptive methodology enhancing sustainability of textile industry

Spinnova, a Finland-based company, has developed what it feels is a disruptive technology for manufacturing cellulose-based fibers. Spinnova’s patented method includes no harmful chemicals and zero waste or side streams.

The fiber recently passed industrial spinning tests, which was an important step in its journey towards a commercially viable ingredient material.

Spinnova’s raw material commitment is to only use Forest Stewardship Council certified wood or waste streams. One of Spinnova’s partners is Austria-based Lenzing AG, one of the world’s largest wood-based fiber manufacturers, with products including Tencel, modal and viscose.

Technology

The process involves the conversion of pulp into the textile fibre without harmful chemicals. The process is based on the mechanical treatment of the pulp, as well as fibre suspension flows and rheology.

The finely ground pulp mass flows through a unique nozzle, where the fibers and fibrils rotate and align with the flow, creating a strong, elastic fibre network. The fibre is then spun and dried, suitable as-is for spinning into yarn and then knitting or weaving into fabric elsewhere.

    Spinnova’s Cellulosic fibre vs. All other cellulose-based fibre processes

    The main differentiator of Spinnova’s method to all other cellulose-based fibre processes out there is that we don’t use dissolving pulp or dissolving processes. Dissolving is used in man-made cellulosic textile fibre processes to break the cellulose into a fine composition we call a polymer dope, to form a fibre suitable for textiles. Until now, this has only been possible by breaking the fibre up with chemicals. The cellulose that comes into our process is micro fibrillated cellulose, which, after a pulping process at a pulp mill, is only mechanically ground into a very fine form.

    Material Insight: Spinnova Fiber

    Spinnova is the only cellulose-based textile fiber that is made from wood pulp and does not use chemicals at any stage. This patented spinning technology is based on the mechanical treatment of the pulp, as well as fiber suspension flows and rheology. It is fully recyclable and directly addresses 5 of the UN’s 17 sustainability goals for 2030. Spinnova is a more sustainable solution to synthetic textiles and cotton because it uses zero harmful chemicals, zero waste, and the only side product is water which is re-used in the process. It mitigates the textile’s industry’s effects on global warming and leaves a smaller carbon footprint in the process.

    Real Recycling With the Collection of Tomorrow: "It's Doable!"

    Bergans of Norway, together with the start-up Spinnova, is pushing real recycling in the "Collection of Tomorrow": whoever owns the award-winning backpack also owns the rights to the material and thus to the products of future forms of recycling. Bergan's Sustainability Manager Christoph Centmayer explains the principle that can change the future of the textile trade.

    Design to last / circulate / die?

    While several sustainable trends are emerging in the textile industry, there are three that are especially interesting – and probably the most meaningful in reducing environmental footprint, in addition to novel materials like Spinnova’s.

    10 Don’ts of a sustainable wardrobe

    According to a recent survey made within young adults, 61% of whom said they would be so interested in sustainable fashion they would pay more for it. This is great news, but let’s face it: sustainable materials are still an emerging industry, although innovators like us are going commercial as fast as possible. There are, however, many things everyone can do – or not do – in order to add to individual sustainability. Going sustainable often means NOT taking certain actions.
