Definitions

  • the present invention relates to a process for the continuous dyeing of cellulose / polyamide blended fabrics, and to the padding liquor used to carry out the process.
  • Cellulose / polyamide blended fabrics are generally dyed using the two-bath method, for example the cotton portion using the pad-steam method in the first step and then the polyamide portion using the pull-out method or vice versa (W. Bernard, practice of bleaching and dyeing textiles; Springer 1966, Page 368 ff). This process proves to be time-consuming and labor-intensive, especially when dyeing large crops.
  • thermosol pad-steam process has become generally accepted for the continuous dyeing of polyester / cotton blended fabrics.
  • the textile material is impregnated with a padding liquor that already contains a combination of polyester and cotton dyes.
  • a padding liquor that already contains a combination of polyester and cotton dyes.
  • the result is a perfectly dyed cellulose fiber, but the polyamide portion is only dyed on the surface, rather soiled, i.e. the dye has not diffused into the fiber under these conditions.
  • the object of the present invention was therefore to develop a dyeing process for cellulose / polyamide blended fabrics which enables the continuous single-bath dyeing of both types of fibers in one operation.
  • thermosol pad steam dyeing process for the continuous dyeing of cellulose / polyamide blended fabrics with a padding liquor containing vat dyes and special 2: 1 metal complex dyes.
  • non-ionic surfactants In contrast to the present application, however, only a few special 2: 1 metal complex dyes (telogens) can be used.
  • GB-A-896 019 describes a process exclusively for dyeing polyamide fabrics using certain metal complex dyes. If necessary, the additional use of dispersants and / or thickeners is recommended, if appropriate in the presence of a humectant and / or acid dispenser.
  • the invention thus relates to a continuous dyeing process for cellulose / polyamide blended fabrics according to the Thermosol-Pad-Steam method, with a padding liquor containing at least one vat dye and at least one metal complex dye, and optionally further additives, characterized in that the padding liquor is a nonionic Contains surfactant or a mixture of non-ionic surfactants.
  • Preferred nonionic surfactants are ethylene oxide adducts of ethylene oxide with alkylphenols, fatty alcohols, fatty amines or fatty acids (ethoxylates); as well as polyethylene glycols.
  • the molecular weight of the ethylene oxide adducts is between 500 and 10,000 and that of the polyethylene glycols between 200 and 6000.
  • ethylene oxide adducts those mentioned under a) are preferred, namely those with a molecular weight of 800 to 1500.
  • Mixtures of the ethylene oxide adducts according to a), b), c) and d) with one another can also be used. These mixtures are obtained by mixing individual adducts or directly by ethoxylating a mixture of the compounds on which the adducts are based. Mixtures of ethylene oxide adducts within a group are of course also possible, such as those obtained by ethoxylating a mixture of fatty alcohols of different chain lengths.
  • Suitable saturated and / or unsaturated fatty alcohols for a) dodecanol, palmityl alcohol, stearyl alcohol, oleyl alcohol or tallow fatty alcohols, preferably a mixture of C 12 to C 19 fatty alcohols.
  • alkylphenols for b) are butylphenol, hexylphenol, but especially isooctylphenol, p-tert-octylphenol, nonylphenol and dodecylphenol.
  • For d) are as saturated and / or unsaturated fatty acids such.
  • polyethylene glycols preferably the low molecular weight z. B. those with a molecular weight from 300 to 500 for use.
  • the nonionic surfactant is advantageously added to the padding liquor in an amount of 2 to 50 g / l, in particular 5 to 20 g / l.
  • Suitable metal complex dyes with which the polyamide portion is colored are, for example, 1: 1 or 1: 2 metal complexes of azo or azomethine dyes or metallized phthalocyanines, such as copper or nickel phthalocyanines.
  • the 1: 1 and 1: 2 metal complexes are preferably 1: 1 nickel complexes, 1: 1 cobalt complexes, 1: 1 copper complexes, 1: 1 chromium complexes, 1: 1 iron complexes or symmetrical or asymmetrical 1: 2 cobalt complexes, 1: 2 iron complexes or 1: 2 chromium complexes, which are used as coloring ligands e.g. B.
  • carboxyl and sulfonic acid groups optionally substituted sulfonic acid amides or alkyl sulfones, halogen atoms or the nitro, acetyl or acetamido group, furthermore alkyl radicals, such as the methyl, ethyl or propyl radical.
  • the azo dyes can be mono-, bis- or polyazo dyes.
  • colorless ligands such as bidentate hydroxyquinoline derivatives, are also suitable in addition to the azo dyes.
  • Metal complex dyes are preferably used 1: 2 in the process according to the invention.
  • the block liquor can in particular also have migration inhibitors, e.g. B. Hypophosphite-acrylic acid telomeres or those based on polyacrylate, these effectively prevent edge runs and a two-sided coloring.
  • migration inhibitors e.g. B. Hypophosphite-acrylic acid telomeres or those based on polyacrylate, these effectively prevent edge runs and a two-sided coloring.
  • buffer substances for. B. ammonium sulfate, sodium hydrogen or dihydrogen phosphate, acids, for. B. acetic acid and / or light stabilizers in question.
  • the fabric first passes through a chemical bath, where the vat dye in alkaline is converted into the water-soluble leuco form using hydrosulfite. Then the fabric enters the air-free steamer, where steaming takes about 1 minute at 100 ° C (saturated steam). After leaving the steamer, the fabric goes into the wide washing machine, where the dyeing is completed by rinsing, oxidizing and soaping.
  • the dyeings obtained with the combination vat dye / metal complex dye on cellulose / polyamide blended fabric in the presence of the specific surfactants according to the present process are distinguished by excellent general fastness properties, in particular by very good light and weather fastness and very good wet fastness properties.
  • the method according to the invention is ideally suited for dyeing large quantities; Compared to the prior art mentioned at the outset, this saves time, is more cost-effective and also saves energy, while at the same time improving shade conformity. It is also surprising that the coloring of the polyamide portion is not damaged by the subsequent development of the vat dye on the cotton fiber.
  • the polyamide fiber component dyed with the metal complex dye survives the treatment with the reducing agent largely without damage; there is practically no destruction of the dye and no color shift.
  • Blended fabrics made of 50% polyamide 6.6 and 50% cotton are dyed on a continuous system using the Thermosol Padsteam process.
  • the pH of the padding liquor is adjusted to 5.5 by adding acetic acid.
  • the textile material has been impregnated with the padding liquor of the specified composition (liquor absorption 60%), intermediate drying (hotflue, temp. 110-130 ° C) and then thermal insulation in a thermo-hotflue for 1 minute at 210-220 ° C.
  • the fabric web then runs through the pad-steam system, where the vat dyes are fixed.
  • the goods first enter the chemical fleet, which contains the amounts of alkali required to reduce vat pigments.
  • B. sodium hydroxide solution and hydrosulfite Then the goods enter the air-free steamer, where steaming takes place for 1 minute at 100 ° C (saturated steam).
  • the textile material runs through the individual compartments of a wide washing machine, where the dyeing is completed by rinsing, oxidizing and soaping.
  • a uniform olive-colored textile material with excellent weather and light fastness and excellent wet fastness properties is obtained.
  • Example 1 If the procedure described in Example 1 is followed, however, a padding liquor is used which, instead of the fatty alcohol ethoxylate, contains the same amount (10 g / liter padding liquor) of one of the following nonionic surfactants, this also gives a uniform olive-colored textile material with excellent weather and Light fastness and excellent wet fastness.
