Definitions

  • the present invention relates to a process for dyeing cellulose fibers and cellulose / polyester fiber mixtures with reactive dyes by the one-bath exhaust process. It is characterized in that dyeing is carried out under HT conditions with dyes which contain a dihalogenotriazinyl, monofluorotriazinyl, fluoropyrimidinyl or dichloroquinoxalinyl reactive group.
  • HT conditions are understood to mean:
  • Temperature cooking temperature and higher, for example 100-130 ° C, in particular about 105-120 ° C.
  • the process is carried out at pH values of about 7-8.5, especially at about 7-7.5.
  • the optimal pH range depends on the type and amount of the dye. The less reactive the dye, the higher it is.
  • the amount of alkaline agent should preferably not be significantly higher than is stoichiometrically required for dye fixation.
  • Suitable buffers for adjusting the pH are, for example, sodium bicarbonate, disodium hydrogenphosphate, borax or conventional buffer systems which are able to maintain the above-mentioned pH range.
  • sodium bicarbonate or disodium hydrogen phosphate are used per liter of dye liquor.
  • the optimal amount depends on the type and amount of the dye used.
  • the process is preferably carried out as an all-in-one process. It is particularly advantageous for reactive dyes with hydrolysis constants K w ⁇ 1. 10 -3 (measured at pH 10.0 and 60 °; see Venkataraman: The Chemistry of Synthetic Dyes; Academic Press, New York, 1972, Volume Vl, page 352), ie in particular for fluoropyrimidinyl, monofluorotriazinyl and dichloroquinoxalinyl dyes .
  • Dyes of the type mentioned are described in large numbers in the literature. Azo, anthraquinone and phthalocyanine dyes are preferably used.
  • the method is preferably suitable for single-bath dyeing of cotton and rayon blended materials in strand and piece, in particular those with polyester, rayon spun cake and rayon cross-wound bobbins as well as mercerized cotton in yarn and piece form.
  • both types of fibers can be dyed simultaneously in cellulose-polyester blends.
  • a dyeing liquor in a dyeing machine e.g. yarn dyeing machine, reel runner or jet dyeing machine
  • which dye e.g. textile material, reel runner or jet dyeing machine
  • textile material e.g. textile material
  • alkali dispenser especially sodium bicarbonate
  • other conventional additives for example salts such as sodium sulfate, and Contains reduction inhibitors such as sodium m-nitrobenzenesulfonate, is heated to 100-130 ° in about 15-60 minutes and held at this temperature until the coloring is complete.
  • 100 parts of a rayon yarn in the form of a spin cake are mixed in a HT yarn dyeing machine with a 75 ° C. warm liquor which contains and the flow direction is changed in the following change: 3 minutes from the inside out and 3 minutes from the outside in.
  • the mixture is then heated to 100 ° C. and 1.5 parts of sodium bicarbonate are added over the course of 10 minutes.
  • the temperature is then brought to 106 ° C. under static pressure and colored at this temperature for 45 minutes. It is then rinsed as usual, soaped at the boil and dried.
  • the mixture is then warmed to 110 ° C. with good liquor circulation and dyed at this temperature for 60 minutes.
  • the temperature of the dyebath is brought to 120 ° C. under static pressure and dyed at this temperature for 90 minutes.
  • the exhausted liquor is then drained and rinsed as usual and soaped at the boil for 10 minutes. A deep blue color is obtained with good fastness properties.
