Definitions

  • the present invention relates to a method for producing etching reserve prints on textile materials which consist of hydrophobic fibers or predominantly contain hydrophobic fibers, e.g. B. in connection with cellulose, in particular with cotton, or in connection with wool, one or more white-etchable disperse dyes and optionally one or more etch-resistant disperse dyes being applied in the form of a liquor or printing paste and then carefully dried or dried and then one Etching reserve printing paste is printed in the desired pattern, which optionally additionally contains one or more etching-resistant disperse dyes, the order of printing on the etching reserve printing paste and the printing paste being reversed and, if a printing paste is used, drying or intermediate drying can be omitted, and subsequent heat treatment at 100 to 230 ° C.
  • hydrophobic fibers or predominantly contain hydrophobic fibers e.g. B. in connection with cellulose, in particular with cotton, or in connection with wool
  • the textile material is colored at the printed areas by the indestructible dye.
  • Colored prints on a dark background can also be obtained if the dark background is made with a mixture of an etchable and a different 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 the dye is not yet fixed , ie Solution of the dye in which hydrophobic fiber takes place.
  • 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, the base dye immigrating into the polyester at the non-printed areas at the same time, 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, a colored residue remains on the etched areas, the shade of which can vary 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.

Disperse Red 303 contains, overprinted in a pattern. After fixing under superheated steam for 7 minutes at 175 ° C. and aftertreatment as in Example 1, a brilliant red etching on a blue background with a sharp stand and very good coloristic properties is obtained.
  • Example 2 A polyester fabric is padded and dried as described in Example 1. Then, as in Example 2, an etching reserve paste, which, however, contains 80 parts by weight of bis (isopropoxythiocarbonyl) disulfide instead of the thioglycolic acid, is overprinted, fixed and aftertreated. In this way, one also obtains a white etching on a blue background with a sharp stand and very good coloristic fastness properties.
