Definitions

  • This invention relates to a method of dyeing textile material made of synthetic fibres, especially of polyester, using aliphatic halogenated hydrocarbons.
  • the objectof the invention is thus to provide a method which avoids these disadvantages and permits very easy dyeing of textile material made of synthetic fibres.
  • this object is achieved in that only those halogenated derivatives of methane, ethane and ethylene are used wherein only two H- atoms are substituted by halogens and whose boiling point is below 85C, and in that these halogenated hydrocarbons in the liquid phase are allowed to act on the textile material at the same time as the aqueous solution or dispersion of dye.
  • the method provided by the invention can be operated in a continuous, semi-continuous or discontinuous operation.
  • the halogenated hydrocarbons and the aqueous dye solution or dispersion can for example be applied by a continuous method to the textile material spread out in 2 web form, with the halogenated hydrocarbons forming not more than 50% of the total bath. Finally the textile material can be left in the coiledstate in a closed cham her.
  • the treatment of the textile material takes place in a closed container, which may for instance be under reduced pressure.
  • the halogenated hydrocarbons form less than 20% of the total dye volume.
  • the textile material may advantageously be subjected in the heated state to the effect of the halogenated hydrocarbons and of the aqueous dye solution or dispersion.
  • a semi-continuous operation if the textile material is to be left in a heated chamber in the coiled state it may be advantageous to cause a preheated foil to run in during the coiling. It is also desirable to produce in the closed chamber a vapour pressure which corresponds to the vapour pressure of the halogenated hydrocarbon at the temperature in the chamber. In this way one avoids unwanted evaporation of the halogenated hydrocarbon, especially when the material is first placed in the chamber.
  • An oil-in-water emulsion is preferably formed from the halogenated hydrocarbon and the aqueous solution or dispersion of dye, however the two components can also be applied directly in sequence to the textile material, when for instance the aqueous dye solution or dispersion is first applied to the textile material, and the halogenated hydrocarbon is then applied. Naturally the reverse procedure is also possible.
  • One of the two components can include an emulsifier.
  • a large part of the dye bath consists of an inert filler material, especially a highly-iluorinated hydrocarbon, which is miscible neither with the aqueous dye solution or dispersion nor with the halogenated hydrocarbon.
  • This filler permits operation with a very small amount of aqueous dye solution or dispersion, but with the dye nevertheless uniformly applied to the fabric. Sincethis inert filler is not contaminated, it can like the halogenated hydrocarbon be easily recovered.
  • the composition of the dyebath of these three components i.e. a large amount of inert fillermaterial and small amounts of the aqueous dye solution and of the halogenated hydrocarbon is. of particular advantage, especially with a discontinuous mode of operation, because of the relatively large amount of dye bath needed in that case.
  • this solution is added 250 ml of methylene chloride (boiling point about 40C) in which 30g of emulsifier has previously been dissolved.
  • a polyester fabric is dipped in the resulting emulsion, heated to 30C, and calendered to a moisture content of The dyed fabric is immediately coiled and kept for two hours in a vapour-tight chamber heated to about the same temperature.
  • the methylene chloride is then removed by heating the fabric to 60C. After rinsing out of the unfixed residual dye an intensely blue dyed fabric is left.
  • EXAMPLE 2 (Discontinuous operation) A laboratory dyeing apparatus for dyeing by the extraction method is loaded with a polyester coil of 800g fabric weight. The apparatus holds altogether l of dye bath. These 10 l are prepared as follows: 40 g of Resolin Red FB liquid 50% are stirred into 9.5 l of wa ter. 500 ml of methylene chloride already containing 50g of emulsifier are emulsified into this solution. The liquor is used for dyeing 1 hour at 40C. During this time the fabric dyes deep-red, while the bath dye content drops. When dyeing has ended the bath temperature is slowly raised to 60C. The evaporated methylene chloride is condensed in a condenser. The bath freed of methylene chloride is drained. Finally the fabric is rinsed and dried.
  • the halogenated hydrocarbon can be added right at the start or when the dyeing temperature is reached, or else one can commence with the emulsion of hydrocarbon and water and add the aqueous dye solution or dispersion.
  • a method of dyeing textile material made of synthetic fibres comprising the step of contacting the material with an aqueous dye liquor containing 20 to 50 ml. of methylene chloride per liter of dye liquor.
  • a method according to claim- 1 wherein the material is contacted with a composition comprising a minor proportion of an aqueous dye liquor containing 20 to 50 ml. of methylene chloride per liter of dye liquor, and a major proportion of an inert liquid which is immiscible witheither the aqueous dye liquor or the methylene chloride.
  • vapour pressure of methylene chloride in the closed chamber corresponds to the vapour pressure of methylene chloride at the temperature in the chamber.
