Development of dyeing natural textiles in supercritical carbon dioxide

Supercritical carbon dioxide dyeing has successfully dyed a range of synthetic textiles including polyester, nylon and PLA. However, the dyes used in the process were not applicable to natural fibres due to the differences in polarity. The research focus will be on the development of natural textiles for cotton dyeing in supercritical carbon dioxide using novel disperse reactive dyes to create covalent dye-textile bonds. A present supercritical carbon dioxide dyeing system will be optimized for process evaluation.
