A method of dyeing natural textile fibres with a dyeing medium comprising supercritical carbon dioxide

摘要

The method of dyeing natural textile fibres with the use of a dyeing medium comprising supercritical carbon dioxide and a dye provides for the dye to be of the water-soluble, polar type and for the dyeing medium also to comprise a polar cosolvent. The latter is preferably selected from the group consisting of methanol, ethanol, water and mixtures thereof.
