Definitions

  • EP-A1-21 432 (not pre-published) is in turn concerned with conversion and etching reserve articles which are obtained when a reactive dye or a mixture of reactive and vat dyes is printed on cellulose fabric as a base in the weakly acidic medium and then a specially activated one Reducing agent from neutral medium and possibly the vat dye is overprinted, whereupon the simultaneous fixation of both dye classes takes place according to a two-phase process.
  • the object of the present invention was therefore to produce white and colored reserves on mixed materials made of polyester and cellulose fibers.
  • This object is achieved according to the invention by applying a slightly acidic preparation to the mixed material, the at least one etchable reactive dye which stains both types of fibers, or a mixture of at least one etchable reactive dye and at least one disperse dye which is mixed with alkali in a water-soluble anionic Form can be transferred, and possibly contains a neutral fixing aid for reactive dyes, then an alkaline etching reserve printing paste is printed on this rear impregnation, which contains a reducing agent and possibly a non-etchable dye in addition to the alkali, followed by fixing with superheated steam or saturated steam in conjunction with hot air takes place, and if the acidic preparation does not contain the neutral fixing aid, treatment with alkaline agents and a steaming process follow.
  • White reserves are obtained by this process.
  • vat dyes, alkali-stable or viable disperse dyes or a combination of such dyes are added to the alkaline printing paste.
  • conversion articles can also be produced if non-etchable dyes are added to the acidic preparation.
  • the colored substrates according to the invention comprise mixed materials made of polyester fibers, in particular polyethylene glycol terephthalate fibers, and natural and regenerated cellulose fibers in all usual mixing ratios.
  • the weakly acidic preparation is advisable by padding or splashing, however also applied by printing, especially when large-area patterns (decks) are pre-printed.
  • the embodiment of the process according to the invention in which the acidic preparation contains one or more etchable reactive dyes which stain both types of fibers, has the advantage that there are no fission products of disperse dyes which can be difficult to remove from the cellulose fiber. These dyes are preferably applied together with the neutral fixing aid for reactive dyes, whereupon they are fixed in a superheated steam atmosphere.
  • Disperse dyes which can be converted into a water-soluble anionic form with alkali, in particular at a higher temperature, are known.
  • the alkali solubility of these dyes is dependent on functional groups, especially esterified carboxy groups or phenolic or enolic hydroxyl groups or a combination of such groups.
  • these disperse dyes no longer attach to the polyester fiber and can also be easily removed from the cellulose fiber.
  • the neutral fixing aid for reactive dyes causes the reactive dye to be fixed on the fund in the course of the steaming operation with superheated steam.
  • these auxiliaries are alkali metal or alkaline earth metal salts of aliphatic or aromatic, preferably low molecular weight, mono- or polycarboxylic acids, in particular alkali metal or alkaline earth metal salts of multiply halogenated low molecular weight aliphatic carboxylic acids and low molecular weight cyclic carbonic acid esters.
  • the alkaline etching can p aste be printed without intermediate drying. In general, however, intermediate drying is recommended.
  • the etching paste contains alkali, preferably in the form of alkali hydroxide or carbonate or a mixture of both, and a reducing agent which is customary in etching and vat printing inks, preferably a stabilized sulfinate, in particular the sodium salt of hydroxymethanesulfinic acid.
  • a suitable dye or a mixture of dyes is added to the alkaline etching paste, which is selected from the range of vat dyes, the alkali-stable dispersion dyes and the combinable dispersion dyes. Combinations of several dyes from different classes are also possible.
  • the alkaline printing paste contains a vat dye
  • treatment with saturated steam at atmospheric pressure follows.
  • the vat dye is incubated so that it can be drawn onto the cellulose portion of the mixed fiber material.
  • vat dyes are very sensitive to temperatures above 100 ° C during the fixing process, but high-temperature fixing is required for the dyes on the polyester fiber portion, it is advisable to add an auxiliary agent that releases water above 100 ° C. This prevents or otherwise at least strongly suppresses the clouding of the color tone.
  • auxiliary agent that releases water above 100 ° C. This prevents or otherwise at least strongly suppresses the clouding of the color tone.
  • auxiliary agents of this type are aqueous dispersions of polymers, for example ethylene polymers, but especially organic dicarboxylic acids which are expediently used in the form of their salts, for example their alkali metal salts. From these aids, 50 to 400 g per kilogram of printing paste are appropriately added.
  • colored reserves are generated with the aid of alkali-stable disperse dyes which are added to the alkaline etching paste.
  • This alkali-stable disperse dye is advantageously used in combination with a vat dye which has the same shade.
  • colored reserve effects are generated with the aid of combinable disperse dyes, which penetrate into the cellulose fiber in a coupled form, where they are firmly anchored in the course of the reoxidation.
  • the fixation of the coloring depends on the dyes used. As mentioned, a saturated steam treatment is required when using vat dyes, which can be omitted if, apart from the reactive dyes, only disperse dyes are used. If saturated steam treatment is carried out, the destruction of the reactive dye by the reducing agent and the conversion of the alkali-sensitive disperse dye into its water-soluble anionic form take place in this step.
  • the disperse dyes are expediently fixed in the same unit as a previous saturated steam treatment with superheated steam or hot air in connection with saturated steam. This also promotes reoxidation of the vat dye. If the acidic preparation contains the neutral fixing aid for reactive dyes, the reactive dye is also fixed in this step.
  • the reactive dye is steamed after the fixation of the other dyes process fixed.
  • alkali is applied to the fiber material, preferably in the form of alkali hydroxide, carbonate, bicarbonate, phosphate or silicate or a mixture of such alkalis. It can be applied in any manner, for example by spraying, padding or splashing.
  • the subsequent steaming process is advantageously carried out as short-term steaming in saturated steam, which requires 2 to 20 seconds.
  • the reactive dyes which can be used in the process according to the invention can belong to the various organic dye classes, for example azo, anthraquinone and phthalocyanine dyes, which contain at least one P-hydroxyethylsulfonic sulfuric acid ester group, vinylsulfonyl group, monochlorotriazine group, dichlorotriazine group, 2,2,3,3-tetrafluorocyclobutane contain acroylamlnooeuvre, vinylsulfonylamino group, ß-Hydroxyäthylsulfonylaminosulfuric acid ester group, P-phenylsulfonylpropionylamino group or a dichloroquinoxaline radical.
  • organic dye classes for example azo, anthraquinone and phthalocyanine dyes, which contain at least one P-hydroxyethylsulfonic sulfuric acid ester group, vinylsulfonyl group, monochlor
  • the disperse dyes that can be converted into a water-soluble anionic form with alkali, preferred are those whose cleavage products are easy to eliminate. Dyes which contain one or more carboxylic acid ester groups and nitro-thiazole dyes are preferred.
  • Disperse dyes with anthraquinone structure which can be linked, and naphthalene di- and tetracarboxylic acid derivatives and quinophthalone derivatives, which are resistant to alkali and reducing agents, are suitable for the colored etching reserve effects.
  • Vat dyes are in particular indigoide, thioindigoide, anthraquinone or naphthochinoid compounds, which are advantageously used in the commercially available dough form.
  • locust bean gum ether thickeners come into consideration. Of this, 50 to 200 g of a 4 to 8% strength aqueous preparation are expediently added per liter of liquor.
  • Suitable thickeners for the printing pastes are, for example, mixtures of degraded types of rubber and low-viscosity alginates or locust bean gum carboxymethyl ether and starch carboxymethyl ether.
  • the goods are treated with superheated steam for 8 minutes at 180 ° C, briefly rinsed, reoxidized at 50 ° C with 2 g / I hydrogen peroxide and 5 ml / I acetic acid, rinsed again and finally with 0.5 g / I of a 20-fold oxyethylated nonylphenol washed at 90 ° C, rinsed and dried.
  • a brilliant red print is obtained on a greenish-yellow background with good fastness properties.
  • the goods After printing and drying, the goods are steamed for 10 minutes at 102 ° C in saturated steam and then for 7 minutes at 175 ° C in superheated steam.
  • the further treatment is carried out as in Example 1.

  • the fabric After printing and drying, the fabric is padded with 50 g / l acetic acid in a block bath with a squeezing effect of 70% and then steamed for 8 minutes at 175 ° C in superheated steam.
  • the result is a deep blue print on a red background with good fastness properties.
  • the fabric After drying, the fabric is printed with a printing ink which, apart from the dye, contains the same constituents as described in Example 1.
