Abstract
A process for the wet treatment of fibrous material especially synthetic fiber strands or cables, wherein the material is conveyed on a liquid-permeable conveyor support while being carried by a liquid bath; the liquid layer is provided above the conveyor support and is maintained, with the liquid flowing by the effect of gravity through the material lying on the support. The flow of liquid takes place uniformly over the supporting surface of the conveyor support.
Claims13
A process for the wet treatment of fibrous material, which comprises producing a first liquid layer in a container, transporting a fibrous material on a supporting surface of a liquid permeable conveyor support through said first liquid layer, maintaining the liquid level of said first liquid layer above said fibrous material on said supporting surface of said conveyor support, producing a second liquid layer in said container, maintaining the liquid level of the second liquid layer below the first liquid layer to provide a free air space between said first and second liquid layers, and flowing liquid in the first liquid layer, by the effect of gravity, through the fibrous material being transported on said conveyor support, the flow of liquid taking place uniformly through the fibrous material and over said supporting surface.
