Abstract:
A PROCESS FOR SUBJECTING A CONTINUOUS LENGTH OF MOVING MATERIAL TO A LIQUID TREATMENT. THE MATERIAL IS INITIALLY SOAKED IN A BATH OF PROCESSING LIQUID WHILE IN A SUBSTANTIALLY TENSIONLESS CONDITION. IMMEDIATLEY THEREAFTER, THE MATERIAL IS GUIDED THROUGH A TREATMENT CHAMBER WHERE
IT IS EXPOSED TO A HIGH VELOCITY OF FLOW OF THE SAME PROCESSING LIQUID.
Abstract:
A SINK ROLL FOR GUIDING AN ELONGATE STRIP TO BE PROCESSED IN A TREATING LIQUID TANK IN A MANNER SUCH THAT SAID STRIP IN MAINTAINED OUT OF CONTACT WITH THE OUTER SURFACE OF SAID SINK ROLL, COMPRISING A SEMICIRCULAR CYLINDRICAL GUIDE WALL PORTION PROVIDED WITH AT LEAST ONE RECESS OF SUBSTANTIALLY RECTANGULAR SHAPE, FLAT GUIDE WALL PORTIONS EXTENDING FROM THE DIAMETRICALLY OPPOSITE EDGES OF SAID SEMICIRCULAR CYLINDRICAL GUIDE WALL PORTION TANGENTIALLY THERETO, AND AT LEAST ONE CHANNEL OPENING IN THE RECESS AND COMMUNICATING WITH A PUMP TO SUPPLY THE PRESSURIZED TREATING LIQUID BETWEEN THE SURFACE OF THE SEMICIRCULAR CYLINDRICAL GUIDE WALL PORTION AND THE STRIP.
Abstract:
A dyeing apparatus comprises a dyeing vessel adapted to contain a dyeing liquid therein, a rotary shaft rotatably disposed as laterally suspended in the dyeing vessel, an impeller adapted to flow the dyeing liquid in a direction parallel to the rotary shaft, and a reel for permitting an article for dyeing to be rolled up thereon, the impeller and the reel being attached to the rotary shaft. The dyeing of the article rolled up on the reel is effected by causing the dyeing liquid to pass by permeation through the article from the lateral terminal part thereof by the rotation of the impeller. The rotary shaft may be rotated reversibly during the course of the dyeing.
Abstract:
The textile web (1) is guided through a relatively narrow shaft the limits of which are formed at least partially by the surface of rollers (2, 3). Nozzles (7), from which a treatment medium can be applied onto the textile web, are arranged in the curved sections (6, 6') of the shaft. Straight sections (8) between the rollers can be kept very short. The device is especially suitable for the treatment of tension-sensitive textile webs.
