The assembly for dyeing fabric piecegoods (4) has a venturi transport jet to move the continuous loop of material within a closed vessel (1), using a gas transport medium of air or an air/steam mixture. The liquid dyestuff is contained in a separate zone (14), with no contact between it and the fabric, to be applied to the moving material in volumes controlled by time, at a point before and/or after the transport jet according to a computed model. The dyestuff is recirculated at the holding zone through a heat exchanger (19), without fabric contact, and taken out under control (29) for application through the dyestuff delivery (20,21). |
