Definitions
- the invention relates to an improved method for producing colored native or synthetic substrates with covalently bound azo dyes produced on the substrate.
- Reactive dyes containing azo groups can be reacted with reactive enolic ones
- Coupling components are made with diazomum compounds.
- the diazonium or the coupling component contains one or more, identical or different reactive molecular building blocks, which are usually called reactive groups.
- the reactive groups are only synthetically inserted into the "color base" after the coupling step. After synthesis has been completed, these reactive dyes are reacted under customary dyeing conditions with the material to be dyed in printing or in various dyeing processes with the substrate.
- the hydrolyzate has a characteristic substantivity that leads to intense dye-fiber Interaction leads and thus the washability of the dye necessary after the dyeing process significantly more difficult.
- a water-insoluble naphthol compound in the form of its water-soluble naphtholate is applied to the material to be printed or dyed, and the material thus impregnated is then reacted with sulfo-free diazonium salts to give the water-insoluble, pigment-like dye.
- a disadvantage of this process is the formation of considerable amounts of unpigmented dyes, so-called colored lacquers, which can form on the fiber and in the dyeing liquors. Because of their inadequate pigment-like character, they have little washability and therefore poor wet rub fastness. They have to be rinsed out after the coupling. This significantly extends the overall dyeing time.
- the coupling component can contain a fiber-reactive group.
- the primer is first primed, an intermediate fixation may be carried out in a sodium chloride bath or by rinsing in sodium chloride solution. In none of the examples is the excess coupling component removed by rinsing before reaction with the diazo component.
- DE-A 2 603 445 and GB-A 1 568 172 it is known to block textile material with water-soluble coupling components, which contain a group which is fiber-reactive in the alkaline medium, from aqueous alkaline liquors, and then by treatment with a diazocom components and acid to bring about the dye formation. Again, there is no indication of rinsing off excess coupling component prior to reaction with the diazo component.
- 1,576,061 relates to a process for dyeing or printing fiber materials, the fiber materials being dissolved with the coupling component treated with a diazotizable amine and sodium nitrite or first primed with a coupling component in the customary manner, if necessary rinsing and then allowing a diazotizable amine to act in the presence of nitrite, or by adding a diazotizable fiber-reactive amine to an intermediate rinse bath.
- cotton jersey is primed with a coupling component, followed by an intermediate rinse and then sodium nitrite and a diazotizable amine are added to the same bath with diazotization and coupling.
- the coupling component obviously does not have a fiber-reactive group.
- DE-A 2 712 088 relates to a further embodiment of DE-A 2 603 446, which consists in using as coupling components those which likewise have at least one fiber-reactive group.
- DE-A 2 712 106 relates to a further embodiment of DE-A 2 603 445, according to which the fiber-reactive coupling component is fixed by heat treatment or lingering in the dyeing of mixed fabrics of polyester and cellulose fibers.
- the invention has for its object to provide an improved dyeing process based on reactive dyes, but which has improved application and ecological properties.
- the invention relates to a process for the production of colored native or synthetic substrates with covalently bonded azo color substances produced on the substrate, characterized in that the hydrolyzate of the dye remains in the process in amounts of at most 1% by weight, based on the dye .
