Definitions

  • the present invention relates to a process for the production of etching reserve prints on textile materials which consist of hydrophobic fibers or contain predominantly hydrophobic fibers, wherein one or more white-etchable disperse dyes and optionally one or more etch-resistant disperse dyes in the form of a liquor or printing paste are applied to the textile material and then carefully dried or dried and then an etching reserve printing paste is printed in the desired pattern, which may optionally also contain one or more etching-resistant disperse dyes, the order in which the etching reserve printing paste and the printing paste are also reversed and, if a printing paste is used, drying or intermediate drying can also be omitted, and subsequent heat treatment at 100 to 230 0 C.
  • the color of the textile material on the printed areas is destroyed by the color at the same time as the background color is destroyed disturbable dye made.
  • Colored prints on a dark background can also be obtained if the dark background is made with a mixture of an etchable and a differently colored, non-etchable dye.
  • the known etching printing process is therefore modified in such a way that the textile material is first padded with a dye liquor containing disperse dye and then carefully dried or dried so that no fixation yet of the dye, ie The dye is dissolved in the hydrophobic fiber.
  • the desired pattern is then printed on the dried or dried-on padded fabric with the etching printing paste and the fabric treated in this way is then subjected to a heat treatment, with the base dye immigrating into the polyester at the unprinted areas, i.e. is fixed, and the dye is destroyed at the areas printed with etching printing paste, i.e. no coloring takes place.
  • This process is also known as etching reserve pressure.
  • etching reserve printing which is simple in itself, involves a number of technical difficulties which often make its use more difficult. It is usually not easy to completely destroy the base dye with the etchant. If this does not succeed, it remains a colored residue on the etched areas, the shade of which can fluctuate between yellow-brown and dull violet or reddish gray tones and which soils the white background at the etched areas. This leads to white etch which appears to be unclean or, in the event that a colored etch is to be produced, to a falsification of the shade of the etchant-resistant dye.
  • etching printing pastes which contain relatively strong reducing or oxidizing agents, e.g. Alkali formaldehyde sulfoxylates, or even heavy metal salts, such as tin-2-chloride.

  • the use of such dyes by the processes described leads to fiber damage due to saponification, which is particularly intolerable in the case of very light, thin qualities.
  • such dyes can generally only be prepared using special, complex processes and from preliminary products produced specifically for this type of dye. They also show defects in the application. So they show a certain affinity after the etching hydrophilic accompanying fabrics and soiling them, or they tend to thermomigration, or they have poor drawing power and thus have only a low color yield on the fiber.
