Definitions

  • the present invention relates to a pad-cold dwelling process for dyeing piece goods of wool or wool-containing fiber mixtures in an acidic medium using reactive dyes.
  • the purpose of the invention explained below is therefore to remedy the shortcomings or disadvantages described at the outset when dyeing wool with reactive dyes by the pad-docking method, in particular to further reduce the energy expenditure for the actual dyeing process and to reduce the output reduce contaminated waste water if possible. From today's perspective, every type of energy saving and easy to remove wastewater play an important role.
  • the sheet-like textile material is dissolved in an aqueous liquor containing the dissolved reactive dyes at a pH between 1.5 and 4, preferably between 2 and 3, and at temperatures up to a maximum of 25 ° C. preferably in the range of room temperature, blocks and then allows this block to remain in the moist state for the dye fixation under the customary acidic conditions and without further addition of temperature for 18 to 36 hours.
  • the method set out above has clear advantages in the energy and wastewater balance over the prior art.
  • any temperature supply can be dispensed with by maintaining a certain pH range.
  • the company consciously refrains from using urea as a fixative to deepen the color.
  • the block fleet therefore only contains inorganic or orga African acids and / or acid salts thereof, which ensure the setting of the characteristic pH range in accordance with the process and whose neutralization is very easy to carry out when treating the waste water.
  • the principle of the present invention is essentially based on the presence of high acid content in the padding liquors used.
  • the new method can be carried out with the safety and reproducibility of the nuance required for practice.
  • the simple and uncomplicated procedure is impressive in this dyeing process. After a normal completion of the dyeing following the dwell process, excellent fastness properties are obtained on the wool dyed in this way. The result is extraordinarily brilliant and deep colors.
  • both organic and inorganic acids or their salts are considered in the process.
  • Potassium bisulfate (bisulfate) sulfuric acid, amidosulfonic acid, formic acid, oxalic acid, succinic acid, tartaric acid and others are examples of this.
  • mixtures of such acidic agents which are capable of realizing the specific pH can also be used according to the invention. If, however, weak organic acids such as acetic acid are used in this process, which only allow the adjustment of pH values in the range from 4 to about 4.8, then it can always be found here that the resulting fastness properties are not so good are what you can expect when using strong acids.
  • urea must also be added to the liquor in such cases, as already explained in DE-C2-26 35 989.
  • the addition of urea can be dispensed with when using strong organic acids which produce pH values of 2 to 3.
  • NEN that the setting of certain acidic conditions allows a temperature reduction in the pad-docking process for dyeing wool with reactive dyes. The lowering of the dyeing temperature is considerable, so that there is a real cold retention fixation.
  • the aqueous padding liquor may also advantageously contain nitrogen-containing oxyethylates or alkyl polyglycol ethers or a mixture of both commercially available classes of compounds to prevent the appearance of gray veils on the wool dyeings produced according to the invention. It was namely found according to the present invention that with the addition of 5 to 25 g / l, preferably 10 to 15 g / l, a 30 to 70% aqueous setting of fatty amines containing ethylene oxide groups, i.e.
  • the organic dyes known under this generic term - regardless of the type of their fiber-reactive group - are considered as reactive dyes.
  • This class of dyes is referred to in the Color Index, 3rd edition 1971 and additions in 1975 as "CI Reactive Dyes” and comprises chemical compounds with a dye character which form a covalent bond with fibers containing OH groups and / or NH groups are able to. These are predominantly those dyes which contain at least one group which is reactive with hydroxyl or amino groups in the fiber material having a polyamide structure, a precursor therefor or a substituent which is reactive with the above-mentioned constituents of the fiber molecule.
  • Particularly suitable as the base of the chromophoric system of these organic dyes are those from the series of the azo, anthraquinone and phthalocyanine compounds, it being possible for the azo and phthalocyanine dyes to be both metal-free and metal-containing.
  • Reactive groups and precursors which form such reactive groups include, for example, epoxy groups, the ethyleneimide group, the vinyl grouping in the vinylsulfone or acrylic acid radical, and also the ⁇ -sulfatoethylsulfone group, the ⁇ -chloroethylsulfone group or the ⁇ -dialkylamino-ethylsulfone group.
  • tetrafluorocyclobutyl series for example tetrafluorocyclobutyl acrylic acid
  • the reactive substituents in reactive dyes are those that are easily removable and leave an electrophilic residue.
  • 1 to 3 halogen atoms on the following ring systems are of interest as substituents: quinoxaline, triazine, pyrimidine, phthalazine, pyridazine and pyridazone.
  • Dyes with several identical or different reactive groups can also be used.
  • Such reactive dyes of the type defined above often have more than one sulfonic acid group (apart from the reactive grouping of the dye) in the molecule, which can be distributed as desired over the chromophore, but are preferably bound to its aromatic radicals.
  • dyes of the vinyl sulfone type are preferably used, with which the fiber reacts via an addition mechanism via the vinyl sulfone form of the dye.
  • coloring substances in the claimed process are the conversion products of such known sulfonyl reactive dyes with, for example, methyl taurine, in which the reactive group is temporarily present in masked form.
  • the claimed process is generally carried out as follows:
  • the wool textile to be dyed is padded with the padding liquor containing dye, acid and possibly auxiliaries at about room temperature.
  • the liquor absorption can be between 50 and 130%, based on the weight of the dry fiber material.
  • the moist goods are then held for about 18 to 36 hours at about room temperature for dye fixation, which is usually done in a rolled-up state with slow rotation of the ball.
  • This measure is expediently carried out with a substantial absence of air, which can be achieved by wrapping the docked goods in a plastic film. If the liquor intake is correspondingly low, the dwelling process with the moist textile goods can also be carried out in a de-tabulated state.
  • the dye is then rinsed, washed and neutralized.
  • aqueous padding liquor of about 20 ° C, which 10 g / l of a 4% aqueous thickener based on galactomannan, 15 g / l of the dye Reactive Blue 19 with the CI no. 61200 and 20 ml / l sulfuric acid conc. (96%) contains and is adjusted to a pH value of 2.8, a fabric made of wool that has not been pretreated with an anti-felt treatment is padded.
  • the liquor absorption is 100%, based on the weight of the dry fiber material.
  • the goods treated in this way are then docked in the moist state resulting from squeezing off the excess liquor and left for 24 hours at room temperature for dye fixation while slowly rotating the ball. The dyeing thus produced is then washed out with water.
  • the dye liquor specified under 1a) was added instead of the substance according to 1b) in this case 15 g / l of an aqueous solution of the reaction product of 1 mol of isotridecyl alcohol with 5 mol of ethylene oxide
  • Example 1a Using an aqueous padding liquor, as indicated in the composition in Example 1a), but instead of the blue dye used there, 20 g / l of the yellow reactive dye of the formula and instead of sulfuric acid 80 g / l potassium hydrogen sulfate containing, at room temperature and a pH of 2.9, a non-felted wool flannel fabric is padded with a liquor absorption of 95% (of the weight of the fabric). After a 20-hour residence time for dye fixation at 20 ° C., the procedure is as described under Example 1a).
  • aqueous padding liquor of about 20 ° C, which 10 g / l of a 4% aqueous thickener based on galactomannan, 15 g / l of the red reactive dye of the formula and Contains 90 g / l tartaric acid, at a pH value of 3, a wool fabric finished with a polyimine resin coating that is felt-free is padded with a liquor absorption of 100% (by weight of the goods). After a dwell time of 28 hours for dye fixation at room temperature, the procedure is as described in Example 1a).
  • Example 1a Using an aqueous padding liquor at room temperature and the composition as given in Example 1a), but in contrast to this instead of the yellow dye there 30 g / l of the commercially available red reactive dye of the formula with methyl taurine containing, a wool fabric that has not been finished with felt is padded at a pH value of 2.5 and a liquor absorption of 100% (by weight of the goods). After a The dyed textile material is washed out with water for 24 hours at around 20 ° C for the moist goods. A full red color results.
  • Example 6 By means of an aqueous padding liquor as described in Example 6, which instead of the dyes there is a mixture of 15 g / l of the yellow reactive dye of the formula 15 g / l of the red reactive dye of the formula such as 15 g / l of the dye Reactive Blue 19 with the CI no. 61200 and 25 ml / l sulfuric acid conc. contains, the procedure for dyeing and dye fixation is as given in Example 6.
