Definitions

  • the present invention relates to a process for the dyeing of textiles which consist of wool which has not been treated with a felt, or which has been treated with a layer of a polyimine resin or a polyacrylic resin, or which contains such (i.e. the wool content in fiber mixtures) by the exhaust method with water-soluble reactive dyes.
  • Felt-free finished wool is wool fibers which, for. B. with a polyimine or polyacrylic resin film (according to the information in Melliand Textile Reports 9/1971, page 1100, or in the Journal of the Society of Dyers and Colors, Volume 88, Number 3/1972, pages 93-100) are.
  • a textile article made from it must be able to withstand the hard stresses not required and not achieved with normal wool, such as washing multiple times at 60 ° C with the use of household detergents containing perborate, without matting, and consequently be color-fast.
  • Such requirements at this high level of fastness, particularly in terms of fastness to washing and sweating, are primarily achieved by dyeing with reactive dyes.
  • the dye manufacturers have put together separate ranges of dyes with the reactive dyes best suited for the type of fiber so equipped and put them on the market.
  • the reactive groups of such dyes are temporarily, i.e. H.
  • the present invention is based on the object of simplifying the currently known dyeing processes for reactive dyes on wool, reducing the amount of their critical points and maintaining the high level of authenticity of the dyeings, which amounts to bringing about the covalent bond between dyes and fibers.
  • aqueous dye liquors containing at least one water-soluble reactive dye in a commercially available form and composition, the solution of which in water results in a pH in the slightly acidic to neutral range, and in that after adding the dissolved dye the liquor together with the textile is heated as quickly as possible and in one go to the dyeing temperature of 110 to 125 ° C and dyed at this temperature for 10 to 20 minutes and that no pH-regulating substances are added during the entire dyeing process.
  • the dye baths are completely removed within 10 to 20 minutes when dyeing according to the new process, so that good dye utilization is ensured.
  • HT conditions according to the invention the differences in dyeing behavior between non-finished and felt-free finished wool when dyeing with reactive dyes largely eliminated.
  • the wool treated according to the invention does not suffer any damage under the above-mentioned conditions, despite the high dyeing temperatures which are unusual for wool, or is kept within a range such as occurs in the usual dyeing processes and is accepted.
  • wool preservatives can be added to the dye baths. It was surprising that the 33% aqueous formaldehyde solution normally used under these conditions in amounts of 5% (by weight of the dry wool) produces only slight losses in color depth, i. H. affects the achievable color depth only slightly.
  • Other wool protection agents, such as B. Protein condensation products do not provide effective wool protection under the HT conditions used.
  • the aqueous dyebath is set at 70 to 80 ° C. together with the goods made from the normal wool or from the wool which has already been treated without felt and which has not undergone any pretreatment with the addition of alkalis or alkali donors, and the liquor is left run 5 to 10 minutes to even out the temperature and to distribute any additives (wool protection agents).
  • the reactive dye or the reactive dye mixture is dissolved in water in a conventional manner and added to the dyebath at about 80 to 90 ° C.
  • the pH of these liquors (measured at 20 ° C) must be in the slightly acidic to neutral range. This means that pH values of approximately 4.0 to 7.0, preferably 6.0 to 7.0, should be maintained. A pH adjustment is not necessary, since aqueous solutions of reactive dyes (in commercial form and quality) are weakly acidic. Process water that has been softened with cation exchangers are often weakly alkaline and therefore require a pH correction in the range mentioned, expediently using acetic acid.
  • the dyeing liquor is heated to the dyeing temperature of 110 ° to 125 ° C. as quickly as possible (within 5 to 10 minutes) and the goods are then dyed at this temperature for 10 to 20 minutes.
  • the liquor and the material to be dyed are then allowed to cool to about 80 ° C. and the dyeing thus obtained is rinsed with warm and cold water.
  • the dyeings produced according to the invention to aftertreatment with 1 to 2% (by weight of the dry goods) aqueous ammonia solution (25%) in certain cases after the end of the dyeing operation .
  • This aftertreatment can be carried out in the dye bath even after it has been exhausted with reactive dye and after cooling to 70 ° to 80 ° C. for a further 5 to 15 minutes or in a freshly prepared ammoniacal aftertreatment bath under the conditions mentioned above.
  • the process according to the invention is also suitable for the single-bath dyeing of mixtures of wool or felt-free finished wool and polyester fibers, the advantages of the novel application technology for the reactive dyes being particularly clear.
  • the dyeing liquors used also contain the predispersed disperse dyes; however, the use of acid donors is not necessary.
  • the measures according to the invention for dyeing these fiber mixtures can be carried out both in one-stage and in two-stage mode of operation.
  • the disperse dye can be added to the dye liquor after it has been exhausted with reactive dye, or the reactive dye can, for example in the case of rapid dyeing processes, also be introduced into the HT apparatus by the disperse dye after a pre-dyeing time for the polyester fiber fraction.
  • the new process now also allows the reactive dyes to be used in an HT dyeing process in addition to the disperse dyes for dyeing such mixtures.
  • the method according to the invention is distinguished from the known, conventional methods for pulling dyeing wool by its simplicity and by a considerable reduction in dyeing times.
  • the fastness properties which can be achieved correspond in all tests to those of dyeings which have been produced by the two-stage processes which have been customary to date.
  • reactive dyes come under this Term known organic dyes - regardless of the nature of their reactive group - into consideration.
  • This class of dyes is referred to in the Color Index, 3rd edition 1971 as »reactive dyes «.
  • These are predominantly those dyes which contain at least one group which is reactive with polyhydroxyl fibers or wool, a precursor therefor or a substituent which is reactive with polyhydroxyl fibers or wool.
  • Particularly suitable as the basic body of the organic dyes are those from the series of the azo, anthraquinone and phthalocyanine dyes, 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 residue, also the ⁇ -sulfatoethylsulfone group, the ⁇ -chloroethylsulfone group or the ⁇ -dialkylaminoethylsulfone group.
  • derivatives of the tetrafluorocyclobutyl series e.g. B. the tetrafluorocyclobutyl acrylic acid in question.
  • the reactive substituents in reactive dyes are those that are easily removable and leave an electrophilic residue. Examples of suitable substituents are 1 to 3 halogen atoms on the following ring system: quinoxaline, triazine, pyrimidine, phthalazine, pyridazine and pyridazone.
  • the temporarily blocked reactive dyes mentioned at the outset such as are obtained, for example, by reacting dyes containing ⁇ -sulfatoethylsulfone groups with N-methyl taurine, also give the new process dyeings on normal wool and on felt-free finished wool, but here, depending on the individual dye content, the Color yield can be reduced compared to the usual dyeing process.
  • Disperse Dyes are suitable as disperse dyes for dyeing the polyester fiber component. Products of this type come, for example, from the series of the azo, anthraquinone or quinophthalone dyes, it being possible for the azo dyes to be used both in metal-containing and in metal-free form. Dyes in the category mentioned are well known.
  • the bath is drained and the wool is rinsed with water.
  • Dyeing is carried out as in Example 1, but here 54 kg of piece of wool in an HT tree dyeing machine at a liquor ratio of 1:20 1.2% (by weight of the goods) of the commercial dye of the formula You get a real red color of the wool.
  • Example 2 It is dyed as in Example 1, but here without the addition of formaldehyde, 35 kg of wool yarn finished with a felt-free finish 6% (of the wool weight) of the commercial dye Reactive Black 5 with the C. L no. 20 505 and 0.1% (by wool weight) of chromium (III) acetate sulfate.
  • aqueous ammonia solution (25%) is added to the dye bath, the dyeing is treated for a further 10 minutes under the given conditions and the yarn thus dyed is rinsed clear with water.
  • the wool is given a felt-free finish using the process described in Melliand Textile Reports 9, 1971, p. 1100, and in the Journal ofthe Society of Dyers and Colorists, Volume 88, p. 93 ff.
