Counter-flow washing. The present invention relates to a process for washing filaments.

A spin cycle mobile washer (SCMW) for manually washing laundry comprises a portable, wheeled frame (F) supporting an axle (A) on each end of which is mounted a wheel (W). A shaft (RS) rotatably mounted on the axle rotates as the axle rotates. An inner wash tub (IWC) is mounted on a rotatable disc (RD) to which one end of the shaft is connected for rotation of the shaft to effect rotation of the tub. This tub has a plurality of paddles (P1-P3) attached to an interior surface so to agitate laundry to be cleaned which is loaded into the tub. This tub is fitted inside an outer wash tub (OWC) with the inner wash tub having openings therein by which water flows through and between the tubs for movement of the wheeled frame by a user to affect the cleaning of laundry.

Repeatable and reliable chemical treatment for loose fibers is achieved by spraying or immersing loose fibers in a chemical treatment bath, and continuously moving the soaked fibers through a continuous centrifuge. The continuous centrifuge controls the wet pickup of the chemical formulation on the fibers and assures a substantially even chemical distribution on the centrifuged fibers. The centrifuged fibers may be dried to fix the chemicals in the chemical formulation to the fibers and/or to remove water from the chemical formulation. Recycling of the chemical formulation from the continuous centrifuge allows for the process to be performed more economically and in a more environmentally friendly fashion.

A process and a system for washing filaments. A filament to be washed and a washing liquid are passed in a countercurrent. The process and the system include two washing stages. In each washing stage the filament is brought into contact with a fresh washing liquid by a washing element in such a way that only an amount of the washing liquid is transferred to the filament, which adheres to the filament itself, for example by adhesion. The washing liquid is then separated from the filament again in each washing stage, and a separated washing liquid is collected in such a way that it is not mixed with the separated washing liquid from other washing stages of the process but is used as the fresh washing liquid in the washing element of a preceding washing stage.
