Definitions

  • the indestructible dye causes the textile material to color at the printed areas, in which case colored prints on a dark background are obtained.
  • Colored prints on a dark background can, however, also be achieved if the dark etched base is made with a mixture of an etchable and a differently colored non-etchable dye and these two types of dye are brought into a common padding liquor.
  • the known etching printing process is therefore modified in such a way that the textile web is first padded with a dye liquor comprising disperse dye and dried or dried on, but no fixation of the dye, i.e.
  • the dye can be dissolved in the hydrophobic fiber.
  • the desired pattern is then printed on the dried or dried-on, padded fabric with the etching printing paste and the padded and printed fabric is then subjected to a heat treatment in which the base dye immerses in the non-printed areas in the polyester fiber, i.e. there is fixed, and at the places printed with the etching the dye is destroyed, i.e. there is no coloring.
  • the technique just described is also referred to as etching reserve pressure.
  • etching reserve printing which is simple in itself, involves a number of technical difficulties which often make its use more difficult. So it is fundamentally not easy to completely destroy the base dye with the etchant. If this does not succeed, then a colored residue remains on the etched areas, the shade of which can fluctuate 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 powerful reducing or oxidizing agents, e.g. Sodium dithionite in combination with alkali, alkali formaldehyde sulfoxylates or even heavy metal salts such as tin-2-chloride.
  • reducing or oxidizing agents e.g. Sodium dithionite in combination with alkali, alkali formaldehyde sulfoxylates or even heavy metal salts such as tin-2-chloride.
  • etching agents e.g. 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 heavy metal etchants they also represent an ecological burden or cause additional expenditure in the purification of the waste water.
  • dyes that are resistant to etchants on the aforementioned basis, and so the selection of etch-resistant dyes that can be
  • Disperse dyes are known from German patent applications DE-A 26 12 740, 2612 741, 26 12 742.26, 12 790, 2612 791 and 26 12 792, which have at least two esterified carboxyl groups in their molecule. Such colorants saponify when treated with aqueous alkalis to form corresponding alkali-soluble compounds containing carboxyl groups.
  • the known acidic etching printing processes which contain either tin-2-chloride or zinc salts of formaldehyde sulfoxyl acid as oxidative etching agents in the printing pastes, mean, in addition to the disadvantage of the corrosive effect on the fixing units, also the risk of wastewater pollution.
  • the present invention also relates to etching reserve means for carrying out the claimed method, characterized in that it contains a mixture of components (a), (b) and (c) of the type specified in claim 1.
  • the mixture component (a) in the etching reserve according to the invention is, for example, 2-, 3- or 4-hydrazinobenzene-carboxylic acid; 2-hydrazino-phenylacetic acid; Hydrazino-naphthatin carboxylic acids; 2-, 3- or 4-hydrazino-benzenesulfonic acid- (5); 4-, 5- or 8-hydrazino-naphthalenesulfonic acid (1); 1- or 6-hydrazino-naphthalenesulfonic acid (2): 4-hydrazino-toluenesulfonic acid (2); 2-or 3-hydrazino-benzene-disulfonic acid (1,4) and 4-hydrazino-benzene-disulfonic acid (1,3) as well as corresponding alkali metal or ammonium salts on the acid residue or salts of hydrohalic acids on the hydrazo group .
  • Mixing component (a) is used in amounts between 5 and 60 g, preferably between 10 and 30 g
  • Mixture component (c) serves to neutralize compound (a); therefore the amount of (c) used depends mainly on the amount of the mixture component (a) present.
  • the pH of the aqueous solution of these neutralized phenylhydrazine derivatives must be adjusted so that the solutions are transparent and clear in water.
  • the aqueous solutions of the 3-component mixture for the etching reserve in the printing paste (i) should expediently have a pH in the range between 6.5 and 8.8.
  • Suitable polyalkylene glycols corresponding to component (b) for the etching reserve according to the invention are primarily polyethylene glycols with an average molecular weight of between 300 and 4500.
  • the amount of the mixture component (b) required in the printing paste (i) is between 30 and 500 g, preferably between 60 and 200 g, per kilogram of the etching printing paste.
  • Suitable textile fabrics in particular woven or knitted fabrics, made of synthetic fibers with a hydrophobic character are, according to the process, all materials that can be dyed by heat-fixable dyes, especially disperse dyes, especially from fibers of linear aromatic polyesters such as polyethylene terephthalate, furthermore from cellulose triacetate, cellulose 2 1/2 -acetate and polyamide fibers. Textile based on mixtures of these synthetic fibers with fibers of natural origin or other synthetic fibers can also be used.
  • the compounds known from this class and suitable for application to the synthetic fibers described above are used from the class of disperse dyes, for example those described in the COLOR INDEX, 3rd edition 1971 and additions in 1975 are listed under the generic name "Disperse Dyes”.
  • the selection of the etchable dyes for the claimed process can only be made experimentally due to the mild effect of the etching reserve.
  • the range of disperse dyes that can be etched according to the present invention is sufficient and ranges from yellow to blue.
  • the etching reserves are then produced in such a way that the undyed textile fabric or knitted fabric is first padded with a dye liquor containing an etchable disperse dye and dried or dried, but no fixation of the dye, i.e. Solution of the dye in the hydrophobic fiber, may take place, and then prints the desired pattern with the etching printing paste on the dried fabric.
  • a dye liquor containing an etchable disperse dye and dried or dried, but no fixation of the dye, i.e. Solution of the dye in the hydrophobic fiber, may take place, and then prints the desired pattern with the etching printing paste on the dried fabric.
  • a further advantage of the method according to the invention is the possibility of storing the goods printed with the printing pastes containing the etching agent after drying.
  • the printed and optionally over-splashed or over-printed goods are fixed in the usual way in hot air or hot steam at temperatures between 160 ° and 220 ° C for 45 seconds to 8 minutes, or in pressurized steam at 1.2 to 1.4 atm for 10 to 30 minutes, preferably 15 to 20 minutes.
  • the completion of the fixed prints requires after rinsing with water, as usual, a reductive aftertreatment and then rinsing and drying again.
  • Printed in punctiform patterns dried and then treated in a high-temperature steamer at 180 ° C. for 7 minutes in order to etch or fix the applied dyes.
  • the goods are then rinsed with water, reductively aftertreated in an aqueous liquor with sodium dithionite, sodium hydroxide solution and a nonionic surfactant, rinsed again with water and finally dried.
  • yellow and white dot-shaped patterns on a violet background are obtained on the goods from example 1 a), and yellow and white dot-shaped patterns on a red background are obtained on the goods from example 1 b).
  • a polyester fabric is printed with the printing paste 1 according to Example 1 d) in any pattern, and this pre-print is grafted wet-on-wet in the same operation with a plating paste of the following composition:
  • the process product is then dried as in example 1, fixed and then finished.
