Definitions

  • the present invention relates to an agent for improving the appearance of used, in particular soiled textiles, especially soaking, washing or rinsing agents, and to a method for improving the appearance of textiles with the aid of the agents according to the invention.
  • photosensitizing compounds i.e. especially dyes that catalyze oxidation processes under the influence of light can be used for bleaching textiles. These compounds can be contained in soaking, washing, rinsing or other cleaning agents or they are used in a separate bleaching process. See British Patent 1,372,036, U.S. Patent 3,927,967, German Offenlegungsschriften 26 13 936 and 28 12 278.
  • the corresponding photosensitizing compound or a soaking, washing, rinsing or cleaning agent containing it is added to an aqueous liquor in which the textiles to be bleached are soaked , washed, rinsed or otherwise cleaned.
  • the textiles must be treated with light
  • Irradiation can take place during the treatment of the textiles in the bathroom (e.g. in the bleaching, soaking, washing or rinsing bath) or after the treatment outside the bath.
  • the still damp textiles can be exposed to sunlight, e.g. while drying on a leash. Irradiation can also be carried out, if necessary, with repeated rewetting of the textiles.
  • the present invention accordingly consists first of all in a means of improving the appearance of used, in particular soiled, textiles, which comprises 0.0001 to 1%, preferably 0.001 to 0.1% of a photoactivator and 0.005 to 1.5%, preferably 0.01 to 0, 5%, based in each case on the total weight of the composition, sulfonic acids distyrylbiphenyl of an optical brightener of the class of acids and salts thereof and / or 4,4'-bis- (1,2,3-triazol-2-yl) Contains -2,2'-stilbene sulfonic acid or its salts, it also being possible for mixtures of several brighteners to be present.
  • Both metal-free phthalocyanines and metal complexes of phthalocyanines can be used as water-soluble phthalocyanines.
  • those of Al, Zn, Mg, Ca, Fe, Na, K, preferably Al and Zn, are used as metal complexes.
  • mixtures of photo actuators can also be used, e.g. Mixtures of various phthalocyanine compounds, such as mixtures of water-soluble Zn and Al phthalocyanine.
  • X 1 and Y 1 are preferably -NH- or -N-alkyl.
  • Halogen is preferably chlorine or bromine, especially chlorine.
  • the 5- or 6-membered heterocyclic rings (R 3 + R 4 ) the morpholine, piperidine, pyrazolidine, piperazine and oxazolidine radicals are preferred.
  • the number of substituents present in the molecule is determined by achieving sufficient water solubility. If - several water-solubilizing groups are present in the molecule, these can be the same or different. As is common in phthalocyanine chemistry, the degree of substitution does not necessarily have to be an integer, since the manufacturing method, e.g. Sulfonation does not always result in uniform products. In general, the total number of water-solubilizing substituents per molecule is between 1 and 4.
  • the phthalocyanines which can be used in the agents according to the invention can also contain other substituents, for example reactive residues customary in dye chemistry, such as chloropyrazine, chloropyrimidine and especially Chlorotriazine residues.
  • substituents for example reactive residues customary in dye chemistry, such as chloropyrazine, chloropyrimidine and especially Chlorotriazine residues.
  • any other substituents can also be used in addition to . be water-solubilizing groups, at most in a number that they do not fall below the required water solubility. However, they can also only be present in very small amounts, for example about 0.1 mol per mol of phthalocyanine compound.
  • substituents are: halogen atoms (including F and J), cyano, optionally substituted alkyl, alkoxy, optionally substituted phenyl and other substituents customary in phthalocyanine chemistry.
  • Preferred additional substituents are fluorine, chlorine, bromine, iodine and cyano, especially chlorine.
  • the molecule contains an anion X to saturate the third valence of the aluminum ion, which is not important for the bleaching effect.
  • This anion is mostly identical to that of the aluminum compound used to make the complex.
  • Particularly preferred photoactivators are aluminum and zinc phthalocyanine di, tri and tetrasulfonates and their salts, which may also contain an additional substituent, e.g. contain a halogen, especially chlorine.
  • Phthalocyanine compounds which are contained in agents according to the invention as a photoactivator and which contain other substituents in addition to the water-solubilizing groups can also be obtained by customary methods.
  • these substituents can already be present in the starting materials used for the construction of the phthalocyanine ring structure (for example phthalic anhydride, phthalodinitrile or imide).
  • the water-solubilizing groups can be introduced (for example by sulfonation), provided that these were not already present in the starting materials.
  • the water-solubilizing substituents can be introduced before or preferably afterwards, for example by sulfonation. If the phthalocyanine ring system is built up from phthalic anhydride or phthalodinitrile in the presence of chlorides, for example AlCl 3 , ZnCl 2 and others, chlorinated phthalocyanines are formed, especially with a chlorine content of 0.5-1.5 mol chlorine per mol phthalocyanine.
  • the water-solubilizing groups can also be introduced subsequently into such products, for example by sulfonation.
  • the methods mentioned can be combined in a suitable manner for the production of mixed-substituted phthalocyanine compounds. All methods are well known in phthalocyanine chemistry and are described in detail there.

  • alkali metal ions M in formula (20) Na and K are preferred.
  • Suitable amine salt ions M are mainly those of the formula -HNR 1 R 2 R 3 , in which R 1 and R are hydrogen or optionally substituted alkyl and R 3 is optionally substituted alkyl.
  • R 1 and R are hydrogen or optionally substituted alkyl
  • R 3 is optionally substituted alkyl.
  • substituted alkyl radicals which preferably have 1 to 4 carbon atoms in the alkyl part, particular mention should be made of hydroxyalkyl, cyanoalkyl, haloalkyl and benzyl.
  • M is preferably hydrogen, sodium, potassium or ammonium.
  • Brighteners of the formula are preferred used, wherein X 'is hydrogen or chlorine and M' is hydrogen, sodium, potassium or ammonium, in particular the brightener of the formula where M "means hydrogen, sodium or potassium.
  • the brightener As a brightener from the class of 4,4'-bis- (1,2,3-triazol-2-yl) -2,2'-stilbenesulfonic acids, which are also contained in agents according to the invention, the brightener of the formula in particular mentioned, wherein M represents hydrogen, an alkali metal, ammonium or amine salt ion.

  • the salt content e.g. Na sulfate
  • the salt content has a certain influence on the effectiveness of the photoactivator.
  • an optimal effect of the photoactivator can be set.
  • the agents according to the invention can be produced without problems by all methods customary in the detergent industry, be they liquid formulations or powders or granules.
  • the good heat resistance of the components essential to the invention also allows them to be added to the slurry of washing powders, which by drying can be dried.
  • the invention further relates to aqueous soaking, washing or rinsing liquors which contain 0.001 to 100 ppm, preferably 0.01 to 10 ppm of a photoactivator and 0.05 to 150 ppm, preferably 0.1 to 50 ppm, in each case based on the total liquor, an optical brightener the class of the distyrylbiphenyl sulfonic acids and their salts or / and the 4,4'-bis (1,2,3-triazol-2-yl) -2,2'-stilbene sulfonic acids or their salts, including mixtures can be contained by several brighteners.
  • Brighteners and photoactivators in the fleets according to the invention are the same as those defined above for the agents according to the invention.
  • the fleets according to the invention are e.g. obtained by dissolving or dispersing the agents according to the invention in water.
  • the individual constituents can be dissolved or dispersed individually or in groups in water, whereupon the liquors according to the invention are formed.
  • a known soaking, washing or rinsing agent can be processed into a corresponding liquor and the photoactivator (s) and the brightener (s) added subsequently in the amount defined above. It is essential that the finished liquors contain photo activator and brightener in the specified concentration.
  • the invention also relates to a process for improving the appearance of used, in particular soiled, textiles, which is characterized in that the textiles are treated in the presence of oxygen with a liquor which contains an agent according to the invention and the textiles are directly in the liquor or in irradiated with light when wet outside the fleet.
  • the textiles are soaked, washed or rinsed in an aqueous liquor according to the invention (as described above).
  • the exposure required to develop the effect of the photoactivator can be carried out with an artificial light source which provides light, for example in the visible and / or infrared range (for example incandescent lamp, infrared lamp), it being possible for the bathroom to be irradiated directly, either by a Light source inside the container in which the liquor is located (e.g. lamp in the washing machine), be it from a light source outside the container.
  • a Light source inside the container in which the liquor is located e.g. lamp in the washing machine
  • the irradiation can also take place only after the textiles have been removed from the treatment bath. In this case, however, the textiles should still be damp or they must be moistened again afterwards.
  • sunlight can also serve as the light source, the textiles preferably being exposed to the sunlight after treatment in the washing or bleaching bath in a moist state.
  • the textiles can preferably be exposed to daylight during drying, for example on a clothesline.
  • the process according to the invention is expediently carried out at temperatures in the range from about 10 to 100, in particular from 10 to 85 ° C., for a period of from 15 minutes to 5 hours, preferably from 15 minutes to 60 minutes.
  • Example 1 A detergent slurry consisting of 50 parts of deionized water and 50 parts of a detergent of the following composition is produced:
  • the aluminum phthalocyanine tetrasulfonate hereinafter referred to as A1PCS
  • ZnPCS zinc phthalocyanine tetrasulfonate
  • Al PC aluminum phthalocyanine tetrasulfonate
  • A1PCS always also means the compound of the formula (25).
  • the photoactivator and brightener are added to the above-defined detergent slurry, which does not yet contain these two components, with largely no light and dried in a drying box and a vacuum of approx. 400 torr at 80 ° C. for 4 hours.
  • the detergent crusts obtained are then pressed through a sieve, beneath which another sieve is located, so that a uniform-grain washing powder is produced.
  • Test strips from the soiled fabrics just described are each washed in a liquor containing 4 g per liter of the detergent defined above at a liquor ratio of 1:20 for 30 minutes at 50 ° C., then rinsed briefly and suspended on a leash in the daylight and then Let dry for 6 hours (equivalent to about 250 Langley).
  • An alkaline solution (pH 9, corresponds to that of the wash liquor) is sprayed every 40 minutes.
  • the washing tests are carried out by varying the photoactivator and / or the optical brightener, with all tests to be compared being carried out in parallel and simultaneously for each type of soiling.
  • Table I shows the composition of the detergent with regard to photoactivator and optical brightener (photoactivator / brightener combinations).
  • the trials 2 and 3 deliver the best results in terms of color removal and brightness of the treated test fabrics for each type of soiling.
  • Example 2 The same detergent compositions are used under the same test conditions as in Example 1. However, a cotton fabric is washed which has been soiled in accordance with Example 9 of German Offenlegungsschrift 28 12 278 with a brown dye. Because of the coloration achieved in this way, bleaching results which are very reproducible are obtained.
  • Example 3 With the aim of quantifying the effects, various variants are tested under the same conditions as in Example 2 using a brightener compound contained in agents according to the invention, namely the brightener B (see Table I). However, the evaluation is not only visual, but also colorimetric. The rags are measured after washing on the RFC 3 color measuring device (from Zeiss) with the 21 filters. The degree of whiteness according to the whiteness formula of Ganz (see Fluorescent Whitening Agents, Chapter V / 2 in Environmental Quality and Safety, Ed. By Coulston & Korte, G. Thieme Verlag Stuttgart) is determined. The combinations listed in Table II below are tested (see also Table I). The degrees of whiteness achieved are also summarized in Table II below.
  • Example 4 Under the same conditions as in Example 3, combinations with a photo activator but different brighteners are tested this time. The results are given in Table III below.
  • Example 5 The cloth from Example 4 are further tested for their intrinsic white to the actual removal of dirt to kontrollie- r s. This is done by measuring the reflection at 460 nm (R value) with xenon lighting with the addition of a UV blocking filter, in accordance with DIN 44 983. The brightener is thus not excited and only the basic white is determined. The results are shown in Table IV below.
  • the two brighteners contained in the agents according to the invention surprisingly result in an additional bleaching effect which is significantly higher than that achieved by the photoactivator.
  • the 6 cotton flaps are then subjected to a 10th wash cycle (as described), which is however stopped after spinning.
  • the 6 spin-damp cloths are now observed in bundle form, also looking into the bundle (corresponding to the process when the housewife takes the washed bundle of laundry from the washing machine and looks at it).
  • the damp bundle of the 6 cotton flaps which was washed with the detergent containing the combination, shows an unsightly yellowish aspect (both after washing at 30 ° C and after washing at 60 ° C).
  • This enormous advantage is achieved both when washing at 30 ° C and when washing at 60 ° C.
  • the effect described is particularly clear when it is observed under low-UV light (incandescent lamp), which generally also prevails in practice when laundry is removed from the washing machine.
