The invention is characterized in that the water-based treatment liquors used contain deaerating components free or at least substantially free from foam under the spraying conditions in dissolved, homogeneously emulsified and/or homogeneously dispersed form in such high concentrations that the textile material is thoroughly wetted almost immediately. The invention also relates to processes for simultaneously carrying out a plurality of treatment stages in a single step and to preparations suitable for these processes, for example preparations and a process for simultaneously desizing, scouring and bleaching cellulose-containing textile materials.
