| 1. An ink-jet printing process for printing textile fiber materials, wherein
the fiber materials are printed with an aqueous ink comprising
(I) at least one fiber reactive dye, and
(II) a di, tri or tetramer of a C2-C4-oxyalkylene or a mono- or di-C1-C4-alkyl ether of a di, tri or tetramer of a C2-C4-oxyalkylene,
said ink having a viscosity from 5 to 20 mPa s at 25°C, and wherein
said ink is applied to the fiber material with an ink-jet print head comprising
an ink supply layer (b) receiving ink from an external ink reservoir, said ink supply layer having a first side and a second
side and comprising, a porous medium having a plurality of pores therein and a plurality of holes extending therethrough,
so as to allow passage of the ink and wherein the textile fiber material is pre-treated with a liquor comprising a pad dyeing
auxiliary comprising a copolymer from acrylic acid amide and acrylic acid monomer in an amount of 0.5 to 5 g/l of liquor,
urea in an amount of 50 to 150 g/l of liquor, a base in an amount of 20 to 80 g/l of liquor, the sodium salt of a nitrobenzene
sulfonic acid in an amount of 5 to 50 g/l of liquor, a softener based on a amino functional siloxane in an amount of 10 to
100 g/l of liquor and optionally a salt, in an amount of 50 to 200 g/l of liquor.
