| titleOfInvention | A method of dyeing a substrate with a reactive dyestuff in supercritical or near supercritical carbon dioxide |
| abstract | The present invention relates to a method of dyeing a substrate with a reactive dyestuff in supercritical or near supercritical carbon dioxide, said substrate being selected from the group consisting of cellulose fibres; modified cellulose fibres; protein fibres; synthetic fibres and any combination thereof, wherein the method comprises dyeing said substrate by contacting the substrate with supercritical or near supercritical carbon dioxide containing a reactive dyestuff and one or more acids in a concentration of at least 0.05 mol.%, calculated on the molar amount of reactive dyestuff that is used in the dyeing method, said reactive dyestuff being a chromophore derivative containing a chromophoric residue and a reactive group, said reactive group comprising a cyclic or heterocyclic aromatic residue that will be protonated under the conditions employed during the contacting, such protonation resulting in enhanced reactivity of the reactive dyestuff towards the plurality of reactive groups contained in the substrate. |
