The machine () for the treatment of fabrics according to the invention comprises a treatment tank () arranged for containing the fabric or other material to be treated (TC) and a treatment liquid. The head losses that the treatment liquid undergoes along the different collecting ducts (A, B) between the treatment tank () and the relative entry nozzle (A, B) in the collector () mutually differ at most of ±10% of the losses themselves. The head losses that the treatment liquid undergoes between each entry nozzle (A, B) in the collector () and the entry () in the chamber () of the pump impeller differ at most of ±10% between the various entry nozzles (A, B). The level of liquid on the bottom of the tank () is more even, and it is thus possible to make the machine () work with very low bath levels. 11: A machine () for the treatment of fabrics , nets , gauzes , felts , non-woven fabrics and other piece or sheet material , comprising:{'b': '3', 'a treatment tank () arranged for containing the fabric or other material (TC) to be treated and a treatment liquid;'}{'b': '3', 'a recirculation system arranged for collecting the treatment liquid still contacted by the fabric or other material to be treated in the treatment tank (), wherein the recirculation system comprises{'b': 11', '3, 'a recirculation pump (′) arranged for pumping the treatment liquid towards the treatment tank ();'}{'b': 37', '37', '3', '39', '11, 'a plurality of collecting ducts (A, B), each of them arranged for taking the treatment liquid out the treatment tank () and bringing it to a collector () feeding the recirculation pump (′), wherein the recirculation system is so provide that{'b': 37', '37', '39', '370', '370, 'each collecting duct (A, B) enters the collector () at a corresponding entry nozzle (A, B);'}{'b': 37', '37', '39, 'all collecting ducts (A, B) mutually feed in parallel the collector ();'}{'b': 37', '37', '3', '370', '370', '39, 'the head losses which the treatment liquid undergoes along ...
