Definitions

  • the invention relates to a process for single-bath, single-stage dyeing of polyester / cellulose fiber mixtures by the exhaust process using a dye bath which, in addition to a disperse dye, contains a reactive dye and 0.1 to 5 g / l of an acid donor effective at the dyeing temperature.
  • the process is characterized in that a reactive dye having a fluorotriazinyl or fluoropyrimidinyl group is used as the reactive dye and the starting pH of the dyebath is adjusted by adding disodium hydrogen phosphate or a trisodium phosphate / monosodium dihydrogen phosphate mixture.
  • DE-A-1 819464 discloses a process for dyeing mixtures of cellulose and polyester fibers with reactive and disperse dyes, in addition to the above-mentioned dyes, alkalis and halogen-containing organic compounds acting as acid donors and, if appropriate, carriers customary for dyeing polyester fibers Dye bath are included.
  • Suitable reactive dyes in the process according to the invention are, in particular, organic dyes from the anthraquinone, azo and phthalocyanine series which have a monofluoro-s-triazinyl radical, in particular those which contain an ether or thioether group or in particular an optionally substituted amino group as further substituents on the triazine ring or else fluoropyrimidine dyes, especially those with a difluorochloropyrimidinyl residue.
  • Such dyes are described in large numbers, for example in British Patents 1,169,254; 1 108 606; 1 526840.
  • Water-soluble derivatives of organic or inorganic acids are used as acid donors, which release acidic groups specifically in the temperature range from 60 to 100 ° C and thus the pH value of the initially neutral to weakly alkaline dye bath during the dyeing process in the acidic range, preferably up to pH Move 4-5.
  • Half esters of sulfuric acid such as lauryl sulfate, hexadecyl sulfate or octadecyl sulfate and preferably 2-ethylhexyl sulfate, butyl sulfate, and the sulfuric acid esters of oxyethylated and oxypropylated alcohols such as.
  • trimethyl phosphate triethyl phosphate, tris (hydroxyethyl) phosphate, dimethyl phosphate, diethyl phosphite, dipropyl phosphite, di-isopropyl phosphite, dibutyl phosphite, dimethyl methanephosphonate, Ethanphosphonklarediethylester, Phosphonopropionchuretrimethylester, Cyanethanphosphonklaredimethylester, Cyanmethanphosphonklaredimethylester, and hydroxyethane Hydroxymethanphosphonklaredimethylester, 2-Chlorethanphosphonklaredimethylester, 2-Chlorethanphosphonklathylester, Acetylphosphonklaredimethylester and diethyl acetylphosphonate and tetramethyl phosphonosuccinate.
  • polyester fiber components may be used for the dyeing of the polyester fiber components.
  • examples include trichlorobenzene, o-dichlorobenzene, methyl cresotlonate, butyl benzoate, o-phenylphenol, p-phenylphenol.
  • the carriers are used in the usual amounts for dyeing polyester fibers and are added to the dye bath after the dye and salt have been added.
  • the process is suitable for dyeing yarn and pieces on packing and cross-winding machines, jet dyeing machines, reel runners and jiggers.
  • the process is generally carried out as follows:
  • the textile material is introduced into a dyebath which has a pH of about 7-10, preferably 7-9 and 0.01-10 g / 1 of a fluorotriazinyl and / or fluoropyrimidinyl reactive dye , 01 ⁇ 10 g / l of a conventional disperse dye, 10-200 g / l of a conventional electrolyte such as sodium sulfate or sodium chloride, 0.1 ⁇ 5 g / l of an acid dispenser and 0.1-10 g / l disodium monohydrogen phosphate or trisodium phosphate monosodium dihydrogen phosphate Mixture and other conventional auxiliaries, for example 1-8 g / 1 of a carrier contains.
  • the dyebath is heated from 30-40 ° C to 95-130 ° C within 1-2 hours and dyed at this temperature for 2-1 hours.
  • the reactive dye is dyed in the alkaline range, preferably at pH 7.5-9 below 100 ° C.
  • the amount of acid donor is measured so that after dyeing the pH is below 7, preferably in the range 4-5.
  • 100 of a knitted fabric consisting of 50 g polyester and 50 g cotton are treated on a HT jet dyeing machine with a 30 ° C. liquor, which consists of consists.
  • the liquor is brought to 130 ° C. in 100 minutes and kept at this temperature for 1 hour.
  • the liquor is brought to 130 ° C. in 100 minutes and kept at this temperature for 1 hour.
  • 100 g of a knitted fabric consisting of 50 g polyester and 50 g mercerized cotton are treated at 75 ° C. for 45 minutes on a HT tree dyeing machine with a liquor which consists of consists.
  • the liquor is brought to 130 ° C. in 55 minutes and kept at this temperature for 1 hour.
