Definitions

• the invention relates to a method for improving the wet fastness of dyeings with sulfur dyes on cellulose.
• Cellulose can be dyed with sulfur dyes by pulling them out of a long or short liquor or by a variety of processes on dyeing machines and dyeing machines.
• Semi-continuously e.g. can be dyed on pad-roll systems or by the pad-docking method or by the cold dwell process.
• Sulfur dyes can also be colored continuously, e.g. according to the pad steam process or the thermosol continuous process, among others
• water-insoluble sulfur dyes are first converted into the soluble, fiber-affine leuco form by reduction, usually with sodium sulfide or sodium sulf hydrate, and are applied to the fiber in this form and then oxidized.
• Modified sulfur dyes e.g. in water-soluble form, commercially.
• the water-soluble sulfur dyes can be dissolved in water without a reducing agent and only become fiber-affine after the addition of reducing agents and alkali.
• reaction temperatures close to 100 ° C. are required for the use of the aftertreatment agents.
• the alkylating aftertreatment agents react not only with the sulfur dye, but also with the cellulose and are thereby anchored to the fiber. In the event of a false color, the auxiliary can therefore no longer simply be removed, but it must be destroyed under such drastic oxidation conditions that fiber damage cannot be reliably avoided if the sulfur dye is to be applied evenly when it is dyed again.
