Abstract: Dying or bleaching apparatus for yarn wound on reels or similar packages, comprising a plurality of small vertical dying boilers (15) arranged on a single circumference each suitable for receiving a mobile reel holder shaft (13) which can be removed at the same time as the others for the subsequent centrifugal water draining and drying operations, operating with less liquid and also capable of being used with fractional capacities with a constant soaking ratio.

Abstract: A beaker for a sample dyeing machine comprises a hollow beaker body and a longitudinal sliding cylinder with flanges on both its ends. The outer wall of the cylinder is uniformly perforated for wrapping of a sample yarn or cloth to be dyed. A plurality of grooves is separately formed on the periphery of either one of the flanges to guide the flow of a dye solution. An annular passage is formed in the interior of the cylinder from one end to the other for allowing a dye solution to flow between the passage and the perforated wall of the cylinder. The beaker thus constructed can dye a sample uniformly and efficiently due to sufficient contact between a sample and a dye solution. The beaker also comprises a hollow tube outside the beaker body for one-way flow of a dye solution, and/or a dispensing device screwed on the top thereof for liquid addition to the beaker. A sample dyeing machine comprises a plurality of the beakers in a fixed rack.

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: An installation is provided for the wet treatment of textile materials disposed on material-carriers, comprising a tank with means for loading or unloading the material-carriers, a means for causing the treatment fluid to flow through said materials and, possible, a heat exchanger, each material-carrier having a box shaped base with an aperture for connection to an aperture of an adjacent material-carrier, or for connection to a first pipe of said fluid moving means which opens into a treatment volume so as to form a first fluid flow in one direction, the flow of said fluid in the other direction following a path which includes at least a second pipe of said fluid moving means also opening into said volume, this latter being limited laterally by walls extending between the floor and the vault of the tank and said first pipe and at least said second pipe each open into said volume through one or more passages formed in the vicinity of the floor of the tank.

Abstract: An apparatus for treating textile materials has an impeller or vane wheel which is disposed in a flow passageway communicating with a circulatory pump and with the interior of a perforated cylindrical beam and which is connected to a shaft of the beam.

Abstract: Apparatus comprising an inner cylinder and an outer cylinder which are telescoped with respect to one another to define between them an annular treatment chamber in which materials, such as textiles, are treated with a fluid medium. The ends of the annular chamber are closed by radial flanges on one of the cylinders, and clearances are sealed by pressurized seals. Material to be treated is wound onto the inner cylinder, and fluid medium is circulated through the chamber while one cylinder is rotated and the other remains stationary. At the conclusion of treatment, one of the cylinders is moved axially with respect to the other so as to expose the inner cylinder for unloading and reloading. Novel T-shaped seals of rubberlike material are mounted within annular grooves in the cylinder flanges, with the head of the T forming a diaphragm and the leg of the T projecting toward the other cylinder.

Abstract: To liquid-treat filamentary materials, such as threads, yarns and textiles, a hollow package of the filamentary material is confined within a vessel so that the package subdivides the interior of the vessel in an inner and a separate outer chamber which communicate with one another only through the thickness of the filamentary material. A foamable treating liquid in unfoamed state is admitted into one of the chambers and is pressed into the filamentary material in order to wet the filamentary material with the liquid. The still unfoamed liquid is then discharged from said one chamber and a pressurized gaseous fluid is forced through the package in order to evenly distribute the wetting liquid throughout the package and to foam it at the same time.
