Abstract: An apparatus for steaming printed fabrics is described which comprises a treating chamber, humidifying passages or channels in the chamber, through which the steam present in the chamber is caused to circulate. The apparatus comprises means for supplying additional humidity by introduction of water into the steam circulating through the channels, and means effective to cause the supplied water, if not vaporized, to collect in the channels so that water in liquid state is prevented from entering the treating and steaming chamber. The humidifying channels are essentially U-shaped and comprise a downwardly directed inlet portion, a passage direction reversing intermediate portion and an upwardly directed outlet portion. Nozzles are provided in the downwardly directed portion as to establish in this latter a dynamic steam entraining effect from the environment. The apparatus is advantageous to obtain the greatest color yield of the dyestuff material present in the fabric.
