Spinnova: Bio-based textile fibre
15 July 2019
Spinnova Oy
Description
Spinnova is a fibre technology company, developing textile fibre directly out of biomaterials without harmful chemical processes or dissolving.
The raw material of the fibre is pulp that is made of FSC (Forest Stewardship Council) certified wood or waste streams such as agricultural waste.
The pulp is mechanically refined into a very fine, paste-like material. Finely ground pulp mass flows through a nozzle, where the fibres rotate and align with the flow, creating a strong, elastic fibre network.
Outcome out of the bio-based textile fibres made from wood is firm white filament with cotton-like strength, stretch qualities and thermal properties same as wool fibres. Depending on the application, fibres could be water repellent, dyed before wet spinning phase or have higher water absorption capacity.
Added value
- Man-made cellulosic fibres without any harmful chemicals and pollution
- Minimal water use
- Utilizing agricultural waste such as stubble reduces emissions as waste would otherwise be burned
Challenges
- High investment cost, Commercial production unit (s) require large funding, whereas production cost is lower in large volumes
- Technology is new, and although fully scalable, technology risk however remains
