Definitions

  • the present invention relates to a method for printing synthetic fiber material in transfer printing and the printing paste used for this printing.
  • the transfer printing process has basically been around for a long time, e.g. from DE-A-2,434,753.
  • sublimable disperse dyes are printed on carrier paper, so-called intermediate carriers, and transferred from there to the textile material by heat and pressure using transfer printing machines.
  • the printing pastes applied to the intermediate carriers are subject to high demands with regard to their viscosity behavior, fastness to rubbing and adhesive strength, etc.
  • printing pastes containing at least one thickener and one binder are used for transfer printing.
  • Known combinations represent e.g. Sodium alginate as a thickener and polyvinyl alcohol as a binder.
  • a printing paste which contains these components has insufficient storage stability and homogeneity, which has a negative effect on the loss of pressure.
  • Synthetic thickeners are an alternative to natural alginates. However, these have proven to be sensitive to electrolytes and are therefore only of limited suitability for printing with anionic and ionically formulated dyes.
  • the present invention is therefore based on the object of providing a printing paste which is free from alginate compounds and at the same time insensitive to electrolytes, homogeneous and stable in storage. Surprisingly, it has now been found that the use of certain water-soluble polymers in printing pastes meets these conditions.
  • a further advantage of the method according to the invention is the fact that component (a) acts simultaneously as a thickener and binder. As a result, the use of a further component acting as a binder becomes obsolete, which considerably simplifies the production and handling of the stock thickening or printing paste.
  • water-soluble polymers (a) there are e.g. Homo-co- or graft polymers which contain ⁇ 20 mol% units of a sulfo-containing monomer.
  • the polymeric compounds (a) are preferably homopolymers of monomers containing sulfo groups or copolymers which contain more than 50 mol%, in particular more than 75 mol%, of monomer units containing sulfo groups.
  • Homopolymers and copolymers which are 50 50 mol%, in particular ⁇ are particularly preferred Contain 75 mol% of 2-acrylamido-2-methylpropanesulfonic acid units.

  • the anionic or nonionic dispersant corresponding to component (c) serves as a protective colloid. This has the task of suppressing the undesired orthokinetic coagulation of the dye formulations used under the influence of high shear forces.
