Abstract
The invention refers to a process and a device for the treatment of fibrous material. In order to provide a process for the treatment of fibrous material which allows for cleaning and preparing fibrous material, the invention provides that fibrous material, especially combed sliver, textiles, non-woven fabrics and wool fiber bunches, are at first cleaned in a cleaning phase with support from a solvent, then dried in a vacuum drying phase, and then surface modified in a plasma treatment phase. The device (100,200) proposed according to the invention for the treatment of fibrous material comprises a cleaning vessel (102,202), a vacuum drier (104,204) and a plasma treatment vessel (106,206) for this purpose.
Claims11
A device for treating fibrous material, especially sliver, textiles, non-woven fabrics and wool fiber bunches as the fibrous material moves along a substantially continuous path of travel comprising a cleaning chamber (102;
- 202) for cleaning the fibrous material utilizing a solvent, a vacuum drier chamber (104;
- 204) downstream of said cleaning chamber, a plasma treatment chamber (106;
- 206) immediately downstream of said vacuum drier chamber, a vacuum pump (142) for creating a strong vacuum in said vacuum drier chamber (104;
- 204) for drying the fibrous material as it moves therethrough;
- a condenser (146;
- 246) for separating fluid from the flow of gas exhausted from the vacuum drier chamber (104, 204) by said vacuum pump (142), said vacuum drier chamber (104;
- 204) including a plurality of side-by-side vacuum chambers (134, 136, 138;
- 234, 236, 238), means for increasing the vacuum in each downstream vacuum chamber as compared to its most immediate upstream vacuum chamber thereby effecting Progressively increasing vacuum from a most downstream vacuum chamber to said plasma treatment chamber (106;
- 206), said condenser (146, 246) having an outlet for discharging separated fluid, and a pump (150) and a supply conduit (148) for conducting the separated fluid from the condenser outlet to the cleaning vessel (102, 202).
