ABSTRACT:
When both colored and white wash are to be laundered together, one has the problem that pigment particles are transported from the colored pieces to the white pieces and the white pieces are discolored. This problem will be eliminated in a novel counterflow cycling washing machine by providing additional components besides the control components for the counterflow which produce a reversal of the usual counterflow to concurrent flow when a colored piece of wash is in the machine or the washing zone. For concurrent flow operation switchover of the valves permits the head of the washing liquid in the upstream compartment of the washing zone to cause the flow through this zone to the downstream compartment where the concurrent flow liquid is discharged.
