Water-soluble monoazo compounds conforming to the general formula (1) ##STR1## where D is monosulfo- or disulfo-phenyl, which may each be substituted by lower alkyl, lower alkoxy, halogen, carboxy and/or lower alkanoylamino, or is mono- or di- or trisulfonaphthyl, K as the radical of a coupling component is para-phenylene, which may be substituted by lower alkyl, lower alkoxy, halogen, lower alkanoylamino, ureido, carbamoyl and/or sulfo, or is 1,4-naphthylene, which may be substituted by 1 or 2 sulfo groups and/or a lower alkoxy group, R is hydrogen or lower alkyl, A is phenylene or a direct bond, W is a direct bond or lower alkylene or an amino group substituted by lower alkyl, although A and W are not both a direct bond, and the group --SO.sub.2 --X is a fiber-reactive group of the vinyl sulfone series.The azo compounds of the formula (1) are fiber-reactive and have very good dyestuff properties. They dye hydroxy- and/or carboxamido-containing material, in particular fiber material, for example cellulose fiber materials, wool and synthetic polyamide fibers, in strong, bright, fast shades. In particular they are suitable for discharge and resist printing.
摘要:
There are described water-soluble fiber-reactive dye-stuffs which possess a triazinylamino radical to which is bonded as second substituent an amino group or an N-containing heterocyclic group which, bonded via an arylene, alkylene or aralkyl radical, possesses a fiber-reactive grouping of the vinyl sulfone series, and to which is bonded as third substituent a sulfonamide group, wherein the sulfone radical is substituted by optionally substituted aryl, alkylenearyl or arylenealkyl or optionally substituted amino groups.The dyestuffs are used for dyeing hydroxy - and/or carboxamido-containing material, in particular fiber material, such as cellulose fibers, wool and synthetic polyamide.

Water-soluble dyes are described, such as azo dyes, metal complex dyes, anthraquinone, phthalocyanine and formazan dyes, which contain a fiber-reactive group of the vinyl sulfone series which, if desired, is bound via a bridging member, and furthermore contain a 4-cyanamido-1,3,5-triazin-6-ylamino radical which is substituted in the 2 position by a group of the formula (2) ##STR1## in which R.sup.z is hydrogen or a lower alkyl group which is unsubstituted or substituted by alkyl, hydroxy, cyano, lower alkoxy, carboxyl, sulfamoyl, sulfo or sulfato or by a substituted or unsubstituted phenyl radical or is a cyclohexyl radical or a substituted or unsubstituted phenyl radical, W is an aryl, alkylenearyl, arylenealkyl, alkylenearylenealkyl or arylenealkylenearyl radical substituted by 1 to 4 water-solubilizing substituents, it being possible for these aryl, arylene, alkyl and alkylene radicals to be additionally substituted and/or interrupted by hetero groups, A is the number zero or 1, and B is the number 1 or 2, the sum of (A+B) being the number 2. The dyes are fiber-reactive and are suitable for the dyeing of hydroxy- and/or carboxamido-containing material, in particular fiber material, such as cotton, wool, silk and synthetic polyamide, by the procedures known for fiber-reactive dyes.

摘要:
A process for dyeing textile fiber materials with water-soluble dyestuffs, in particular anionic dyestuffs, and of these in particular those having a fiber-reactive group, in which the dyeing is carried out using low-electrolyte or entirely electrolyte-free and/or low-alkali or entirely alkali-free dye liquors or printing pastes and a fiber material which has been modified with a silane compound containing amino groups is used as the textile material. The fiber material is modified by applying the silane compound containing amino groups to the material in aqueous solution and subjecting the impregnated material to a heat treatment. Novel silane compounds which contain a secondary amino group and can likewise be employed for the purpose mentioned are furthermore described.
