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.
  • a pad-cold dwelling process for dyeing piece goods of wool or wool-containing fiber mixtures in an acidic medium using reactive dyes.
  • For dyeing textile fabrics made of wool there are in practice, in addition to more or less continuous processes, for example according to the Klotz warm retention method in accordance with the German patent specification DE-C2-26 35 991, for this task there are also pronounced block docks. Process as described for metal complex dyes in German patent DE-C2-26 35 990 and for reactive dyes in German patent DE-C2-26 35 989.
  • heat must be applied either during the padding process or during the dwell or also in both operations.
  • the padding process runs between 60 ° and 80 ° C and the residence temperature subsequently required for dye fixation is then again 75 ° to 85 ° C.
  • a cold storage process for pad dyeing wool and / or silk with reactive dyes under acidic conditions has been described in FR-A 1 421 945. Even if the dye fixation can be carried out in accordance with this known technique at room temperature in the absence of hydrotropic substances such as urea, in this case it is absolutely necessary to use a cationic surface-active agent and to have a large amount of acid in the padding liquor.
  • the said aid forms a coacervate with the anionic reactive dyes, which is intended to ensure the levelness of the dyeings by blocking the solubilizing groups of the dyes and releasing the latter only slowly to the fibers and for reaction.
  • 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 reduce the energy expenditure for the actual dyeing process even further 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 textile material is mixed with an aqueous liquor which has the dissolved reactive dyes but no urea 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, and then this padding can remain for 18 to 36 hours in order to fix the dye in the moist state under the customary acidic conditions and without further addition of temperature.
  • 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 padding liquor therefore only contains inorganic or organic 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 a relatively 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 that the resulting fastness properties are not so good are how to get them at the Use of strong acids can be expected.
  • urea must also be added to the liquor in such cases, as already explained in DE-C2 2 635 989.
  • the addition of urea can be dispensed with when using strong organic acids which produce pH values of 2 to 3.
  • the setting of certain acidic conditions would allow the temperature to be lowered 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 alkylpolyglycol ethers or a mixture of both commercially available classes of compounds to prevent the appearance of gray haze 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, of 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 "C.I. Reactive Dyes” and comprises chemical compounds with dye character which are able to form a covalent bond with fibers containing OH groups and / or NH groups. These are predominantly those dyes which contain at least one group which is reactive with hydroxyl or amino groups in the fiber material with 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, the ⁇ -sulfatoethylsulfone group, the ⁇ -chloroethylsulfone group or the ⁇ -dialkylamino-ethylsulfone group.
  • tetrafluorocyclobutyl series e.g. Tetrafluorocyclobutylacrylic 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 e.g. Methyl taurine in which the reactive group is temporarily masked.
  • the moist wool textile for dye fixation is then held at about room temperature for 18 to 36 hours, which is usually done in a rolled-up state with slow rotation of the ball. This measure is expediently carried out with the 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 can also be carried out with the damp wool textile in a de-laminated state. The dye is then rinsed, washed and neutralized.
