Supercritical CO2 Lab Dyeing system

There is a joint wish from Swedish School of Textiles, TEKO and Swedish textile industry to become leading in the domain of effective textile coloration processes and preparation with limited water use. A jointly defined area of interest is dyeing using supercritical CO2 (see e.g. the report about the visit of TEKO to DyeCoo in Weesp and their pilot scale test facilities in Delft, both in The Netherlands). Key objective of the application is to strengthen the facilities for research and education at Swedish School of Textiles in the domain of more effective coloration processes.

Start date


As a first step in supercritical CO2 dyeing THS wishes to invest in lab scale technology. Supercritical CO2 dyeing is not labour intensive compared to conventional processes and is considered especially interesting for Swedish textile industry because of significant savings in energy, chemicals and water while producing high quality products thereby creating new opportunities.

The equipment will support research and education at The Swedish School of Textiles in advanced novel sustainable dyeing technology and dyeing chemistry and the development of Swedish textile industry in these areas. The initiative is part of an overall approach responding to the needs of Swedish textile industry demanding for novel sustainable and competitive textile dyeing processes and changing production strategies. A technology with large potential in that domain is dyeing supercritical CO2. The technology has fairly recently been embraced by large companies such as Nike, enabling introduction of the technology at full scale in textile industry.
