| titleOfInvention | Process for the dyeing or printing of textile material of cellulose fibers or mixtures thereof with other fibers with reactive dyestuffs |
| abstract | Abstract of the disclosure Certain reactive dyestuffs of commercial constitu- . tion are available in a form which does not react with cellulose fibers and have therefore to be converted into their reactive form before being able to undergo a covalent bond with the fiber materials. The methods hitherto applied in the practice for this purpose are unsatisfactory because they either do not produce a suffi-cient amount of reactive dyestuff under the prevailing conditions, or due to susceptibility of the converted form to hydrolysis, portions of the dyestuff are in activated, thus resulting in dyestuff losses in both cases. In accordance with the invention these drawbacks are overcome by converting first the dyestuffs to their fiber-reactive form, before dyeing or printing, by treating them under correspondingly typical conditions, for example in an alkaline medium, and chemically stabilizing then this converted form by alteration of the pH, for example to the acidic range. The dyestuff formulations so obtained are then used for the dyeing or printing of cellulose fibers in a neutral to acidic pH range. This is the decisive condition for acceptable yields as compared to the hitherto known operation modes. |
