Definitions
- the present invention relates to a process for the production of reserve effects on textile materials based on mixed fibers of polyester and cellulose, in particular polyester-cotton fibers, by impregnating the materials with dye liquors which, in addition to conventional dyeing and padding aids, contain disperse and reactive dyes which contain the reservation agents react and which may contain further dispersing and reactive dyes which are resistant to the reservation agents, drying or drying the padded materials and then printing on a reserve paste which, if desired, in addition to the reservation agent contains dispersing and reactive dyes which are resistant to the reservation agent, heat treatment at temperatures from 100 to 190 ° C and subsequent alkaline fixation of the reactive dye in a manner known per se, characterized in that the etchable disperse dyes are those of the formula 1 wherein R 1 is hydrogen, cyano, optionally substituted alkyl or phenyl; X 1 is hydrogen, halogen, optionally substituted alkyl or alkoxy; Y 1 is hydrogen, halogen, optionally substituted alkyl or
- deralkylcarbonyl, sulfamoyl, lower alkylsulfonyl, lower alkylcarbonylamino or lower alkoxycarbonyl and Z represents hydrogen or lower alkyl; or disperse dyes free of water-solubilizing groups, which contain at least two carboxylic ester groups, as etchable reactive dyes those which contain reactive radicals of the formulas III to VI in which M is hydrogen or a metal cation and hal is halogen, and a reserve paste which contains a) an alkali metal sulfite or an alkali metal hydrogen sulfite in combination with alkali metal carbonate or alkali metal hydrogen carbonate and optionally an aldehyde and b) optionally a nonionic detergent as the reservation agent.
- the textile material is colored at the printed areas by the indestructible dye.
- Colored prints on a dark background can also be obtained if the dark background is made with a mixture of an etchable and a differently colored non-etchable dye by introducing both types of dye into the padding liquor.
- German patent specification 23 26 522 describes a process for producing reserve effects with reactive dyes on native or regenerated cellulose fiber materials.
- the textile material is printed with sulfites, thiosulfites or thioureas as a reservation agent, alkalis as a fixing agent and reactive dyes, which a) react with the reservation agent and have the ß-sulfatoethylsulfonyl or ß-sulfatoethylsulfonamide group as reactive group and b) do not have on fixing react with the reservation agents and have as a reactive group the chloraminotriazine, dichloropyrimidine, trichloropyrimidine, dichlorotriazine, monochlorotriazine, quaternized chlorotriazine or the dichloropyridazine group, in the form or overpressure process, then dries and fixes the dyes by steaming or Hot air treatment.
- the Simpl se 'he method of ⁇ tzreservedrucks includes a number of technical difficulties that make its use often. It is usually not easy to completely destroy the base dye with the etchant. If this does not succeed, a colored residue remains on the etched areas, the shade of which can vary between yellow-brown and dull violet or reddish gray tones and which soils the white background at the etched areas. This leads to white etching which appears to be unclean or, in the event that a colored etching is to be produced, to a falsification of the shade of the etching-resistant dye.
- etching pastes which contain relatively strong reducing or oxidizing agents such as sodium dithionite in combination with alkali, alkali formaldehyde sulfoxylates or even heavy metal salts such as tin-2-chloride.
- strong etching agents such as sodium dithionite in combination with alkali, alkali formaldehyde sulfoxylates or even heavy metal salts such as tin-2-chloride.
- these etchants are usually not cheap, and in the case of Sc l lwermetalliserstoff they represent an additional environmental burden or they cause additional expenses in the purification of waste water.
- dispersions and reactive dyes that are resistant to such etchants, and so the selection of etch-resistant dyes that can be used to produce colored etchings is relatively small.

- the process according to the invention is carried out in a manner known per se by padding the textile material composed of polyester and cellulose fibers with dye liquors which contain one or more of the above-mentioned alkali-etchable disperse dyes and one or more reactive dyes which contain one of the above-mentioned reactive radicals of the formulas III to VI, preferably the ⁇ -sulfatoethylsulfonyl or ⁇ -sulfatoethylsulfonamide groups, contain, in addition to the known customary dyeing aids, such as, for example, dispersants, wetting agents, foam suppressants and padding aids and, if colored etching prints are to be produced, additionally disperse and reactive dyes which are resistant to the etchant , and squeezing the padded fabric webs to a liquor absorption of 50-120%.
- dye liquors which contain one or more of the above-mentioned alkali-etchable disperse dyes and one or more reactive dyes which contain
- the fabric webs are then dried by warm air with any preceding infrared radiation, the temperature being approximately 80 to a maximum of approximately 150 ° C. with a corresponding reduction in time.
- the fabric webs prepared in this way are then included the etching reserve printing paste, which contains the reservation agents described above and the additives known in printing pastes for textile printing, in particular thickeners.
- the padded and printed textile fabrics are subjected to a heat treatment between 100 and 190 ° C. The heat is supplied by means of superheated steam.
- the heat treatment effects a) an inhibition of the reservable dispersion and reactive dyes at the points printed with the reserve paste and a fixation of the possibly non-reservable dispersion and reactive dyes, b) a fixation of the dispersion dyes at the points not printed with reserve paste and, if the padding liquor contained an alkali metal formate, the reactive dyes at the same time.
- Hiarbet is
- the dyeings or prints are rinsed hot and cold and dried.
- the K lotzflotte except reservable disperse and reactive dyes additionally includes those that are resistant to the resisting agent, and thus will not be destroyed by the discharge reserve printing pastes used according to the invention. If one proceeds as above, then multicolored designs are obtained.
- a further embodiment of the method according to the invention consists in that the dyes which can be reserved are not applied to the entire fabric by padding with a pad liquor but are also printed on the fabric in the form of printing pastes and then overprinted with the etching reserve printing paste. The textile prints are then fixed and completed as described above. With this method, too, it is possible to add dyes that are resistant to the reservation agent to the color printing pastes printed on first.
- etching reserve printing pastes which in turn contain dyes which are resistant to the reservation agent, are printed on the fund which is padded or printed with reservable dyes. With subsequent fixation and completion of the textile materials as described above, multicolored designs are also obtained here.
- the disperse dyes of the formula I are present in the padding liquors or in the printing pastes in finely dispersed form, as is customary and known for disperse dyes, while the reactive dyes are dissolved.
- the padding liquors or printing pastes which are to be used according to the invention are also produced in a manner known per se by mixing the liquor or printing paste components with the necessary amount of water and liquid finely dispersed or solid redispersible formulations of the disperse dyes and solutions or formulations of the Reactive dyes.
- Dispersion dyes which are resistant to the reservation agent and which can be combined with the reserved dye of the formula I to produce multicolored designs are the known commercial dyes from the group of azo or azomethine, quinophthalone, nitro or anthraquinone dyes.
- Some examples of resistant disperse dyes are:
- This solution is stirred into 500 parts by weight of a thickening stock, the 230 parts by weight of an aqueous 4% alginate thickening and 80 parts by weight of an aqueous.
- a thickening stock containing 10% starch ether thickening, 85 parts by weight of water, 25 parts by weight of an aqueous 10% solution of the condensation product of polyglycol 2000 with stearic acid and 80 parts by weight of white spirit.
- 100 parts by weight of the etching reserve are then added, which was previously prepared by mixing 65 parts by weight of a 40% aqueous glyoxal solution, 310 parts by weight of sodium bisulfite solution 38 ° Be, 125 parts by weight of water and 500 parts by weight of sodium hydrogen carbonate.
- a leached mixed fabric made of polyester cellulose 70:30 is padded with the dye liquor described in Example 1, carefully dried in a hot flue at 80-100 ° C. and overprinted in film printing with a printing paste consisting of 40 parts by weight of the liquid commercial form of C.I. Disperse Red 200, 30 parts by weight of the commercial form by C.I. Reactive Red 33, 80 parts by weight of urea,
- a block fabric of polyester and mercerized cotton in the ratio 65:35 is padded with a dye liquor composed of 150 parts by weight of a 20% liquid setting of the dye of the formula 40 parts by weight of the commercial form of CI Reactive Blue 122, 767 parts by weight of water, 3 parts by weight of sodium chlorate, 20 parts by weight of an antimigrant based on polyacrylic acid, 20 parts by weight of sodium formate. It is carefully dried in a hot flue at 80-100 ° C. and overprinted in rouleaux printing with a printing paste consisting of 60 parts by weight of the dye of the formula
