There is disclosed a process for printing cellulosic textile material with reactive dyes which contain at least one monohalotriazine radical, which process comprises printing said material, without the addition of urea, in a single step and wetting the dried printed goods with water for the fixation step. The novel process gives level and deep prints of excellent appearance without the use of urea.

Process for printing cellulosic textile material with reactive dyes:

The invention relates to a process for fixing azo, metal complex azo and formazan dyes on textile fabrics with hot steam to give stable shades, which process comprises fixing textile fabrics dyed or printed with said dyes in hot steam that contains at least 0.5% by volume of air.

Process for fixing dyes and prints with hot steam containing air

The invention relates to a process for printing cellulosic fibres or cellulose-containing blend fibres with reactive dyes or dye mixtures which contain a reactive dye and subsequent fixation, which comprises printing these materials with a print paste containing at least one water-soluble reactive dye of the formula

The invention relates to long-shelflife print pastes containing at least one water-soluble reactive dye of the formula

Long-shelflife print containing reactive dye and alkali acetate pastes

Dyes difficultly soluble or insoluble in water are used together with specific auxiliaries to dye or print textile material made from cellulose fibres, or mixtures thereof with synthetic fibres. These auxiliaries effect an increased dye yield, particularly on the cellulose material, and level tone-in-tone dyeings on mixed fabrics.

Process for printing or pad dyeing of textile material made from

Process for the pad-dyeing and printing of textile material made from mixed fibres of cellulose and polyester, which process comprises impregnating of printing the textile material with a dispersion of a disperse dye containing at least one hetero atom which can be alkylated; treating the textile material, before, during or after the impregnating or printing operation, with a compound containing at least two epoxy groups or groups convertible into epoxy groups; and subjecting the material impregnated or printed with dye and epoxy compound to a heat treatment.

Process for the pad-dyeing and printing of textile material made from

Described is a process for the tone-in-tone printing and pad-dyeing of textile material made from fibre mixtures of synthetic and natural material with at least one disperse dye with the use of solvents having swelling properties, which process comprises printing or impregnating the textile material with a printing paste or padding liquor in which one or more disperse dyes have been produced by reaction of coupling components with diazo components; subsequently subjecting the printing or the dyeing, after intermediate drying, to a heat treatment and finally to the finishing process. There are obtained in the case of many disperse dyes when they are produced in the printing paste or padding liquor by the process of the invention better fixings on the natural constituent of the mixed fibres than when the same dyes are firstly produced and then added in the finely-dispersed form to the printing paste or padding liquor.

Described are aqueous, stable, highly concentrated, finely dispersed, flowable preparations of dyestuffs and optical brighteners insoluble to difficultly soluble in water, which preparations have a low content of dispersing agent and a particle size smaller than 10 .mu., particularly smaller than 2 .mu., characterized in that these preparations contain at least 10 percent by weight of water, at least 30 percent by weight of a finely dispersed dyestuff or optical brightener insoluble to difficultly soluble in water, and a mixture consisting of at most 10 percent by weight of an anion-active dispersing agent, at most 5 percent by weight of a nonionic dispersing agent and at most 35 percent by weight of a hydrotropic agent, as well as, optionally, further additives which preparations are useful for the dyeing, printing and optical brightening of textile material in a conventional manner or for the production of printing pastes having an aqueous base or a water-in-oil-emulsion base which printing pastes are useful for the printing of carrier materials, particularly paper with application of dyestuffs or optical brighteners suitable for transfer printing and use of the printed carrier materials in the transfer printing process on textile materials.

New aqueous, stable, highly concentrated, finely dispersed, flowable dyestuff preparations having a low content of dispersing agents and a high content of dyestuff insoluble to difficultly soluble in water are described, which dyestuffs have a particle size smaller than 10 .mu., particularly smaller than 2 .mu., the said preparations being characterised in that they contain at least 10 percent by weight of water, at least 30 percent by weight of a finely dispersed dyestuff, especially a disperse or vat dyestuff, and a mixture consisting of at most 10 percent by weight of an anionactive dispersing agent, at most 5 percent by weight of a nonionic dispersing agent and at most 35 percent by weight of a hydrotropic agent as well as, optionally, further additives. The said dyestuff preparations are especially useful for the preparation of printing pastes having an aqueous base or a water-in-oil emulsion base, which themselves can be used preferably for the printing of carrier materials, particularly paper, suitable for transfer printing.

Continuous process for the optical brightening and printing of organic fiber material, wherein the material is dry cleaned and at least one optical brightener applied from an organic liquor, the said material being then intermediately dried, printed, and subsequently finished by a heat treatment.

Continuous process for optical brightening and printing of organic

Described is a process for the semi-continuous or continuous dyeing and printing or optical brightening of cellulose materials by impregnation of the material with an aqueous liquor or printing paste containing at least one fibre-reactive dyestuff or fibre-reactive optical brightener, wherein subsequent to impregnation, fixing of the dyestuff or optical brightener is performed in a salt-free single-phase bath containing at least one alcohol and alkali and optionally water. By this process there are obtained dyed or optically brightened cellulose materials having fastness properties equivalent to those obtained in the conventional manner. An advantage of the present process, in contrast to the usual processes, is that the waste water is not polluted by large amounts of salt.
