Spinnova's Inherent Dyeing Method for Cellulose Fibres

Updated : 09-Sep-20

Inherent Fiber Dyeing Method

The inherent dyeing developed by Spinnova and Kemira is a process in which the cellulosic fiber mass is dyed before extruding into filament. Spinnova’s innovation originates from the pulp and paper industry.

Sustainability Benefits

  • Inherent dyeing avoids the excess use of water, energy, heavy metals and other harmful substances that go into dyeing fibre, thread and fabric.

USP

  • The efficiency in the use of its resources, is the main advantage of the inherent dyeing process, over its non eco-friendly alternatives.

End user sector

  • Apparel and Garment Manufacturers
  • Eco-Fabric Design Studios
  • Sustainable Textile Production Facilities
  • Denim Textile Manufacturing

How does this work?

  • The process is based on mechanical treatment of the pulp.
  • The finely ground pulp mass flows through a unique nozzle, where the fibres and fibrils rotate and align with the flow, creating a strong, elastic fibre network. The fibre is then spun and dried, suitable for spinning into yarn and then knitting or weaving into fabric elsewhere.
  • There are no waste streams in this closed process. Its only side product is evaporated water, also recycled back into the process.
  • This method includes no dissolving or any other harmful and complex chemical processes.


 

About the Company

Spinnova was founded in 2015. The company's vision is a more sustainable textile industry, where sustainable cellulose-based materials are a cost-efficient, environmentally friendly and preferred option for brands, and available to all consumers.After two years of laboratory scale R&D, the technology was scaled up to a continuous pilot scale that was specifically built for this. The technology has been scaled up from a small pilot scale to an industrial pilot scale in December 2018, when the construction of their pilot line was completed. They will be finalizing product properties and production processes, while working on selected prototypes with partners.
