ABSTRACT:
An apparatus is described for continuously dyeing textile fabrics. The apparatus may be best described in terms of its operation as follows: The fabric is preheated in a chamber and then impregnated with a bath consisting of dyestuff dissolved in a solvent in another chamber. Then the fabric is treated in a developing chamber where the dyestuff is fixed thereon by evaporation of the solvent. The excess solvent is then eliminated from the fabric in a water vapor atmosphere. The treatment in the developing chamber is effected by passing the fabric continuously and alternately a plurality of times to and from a zone of saturated solvent vapor and a zone of superheated solvent vapor. The solvent in these two zones is substantially the same as the solvent in the bath.
