Production of dyeings by the inkjet printing technique on modified fiber materials using anionic textile dyes |
摘要 |
There is described a process for dyeing sheetlike fiber materials, in particular those made of or containing cellulose fibers, with anionic dyes, in particular those having fiber-reactive groups, which comprises applying an alkali-free and preferably low-electrolyte or completely electrolyte-free aqueous solution of the anionic dye by the inkjet printing spray technique to a fiber material which has been pretreated and modified with a compound that contains one or more primary, secondary or tertiary amino groups or quaternary ammonium groups, which amino/ammonium groups may be part of a heterocycle. There is generally no need for an aftertreatment by washing. The costly treatment of wastewaters resulting from the excess dyeing liquors otherwise obtained is eliminated. If fiber-reactive dyes are used, fixation by means of alkali is not necessary; it is generally effected by a short heat treatment.
