  • Patent number: 4164051
    Abstract: A method for continuously dyeing a thick textile material such as a blanket or carpet material or the like. The thick textile material is arranged to be continuously pulled upward and guided over a slanting plate from a lower position to a higher position. A nozzle tube is arranged to spray a dye solution at the thick textile material in an atomized state while the textile material is on the move being guided upward along the slanting plate. The spraying quantity of the dye solution discharged out of the nozzle tube is set to have all of the sprayed quantity of the dye solution absorbed by the thick textile material without having any superfluous portion of the solution flowing down and yet to ensure sufficient impregnation of the textile material with the dye solution. The textile material impregnated with the dye solution is further continuously fowarded and passed through a hygro-thermic treatment chamber and a water washing device.

  • Patent number: 4116627
    Abstract: For sealing a high pressure steamer air, pressurized to a level higher than the internal pressurized medium, in the drum body of the high pressure steamer is directed against the mutually contacting portions of rubber seal rolls. Initially, the pressurized air flows over the outside of a cylindrical duct extending between the opening for the passage of textile articles into the drum body of the steamer and the rubber seal rolls and the air serves to block the flow of the pressurized medium within the steamer through the opening. Sealing plates positioned between the interior of the steamer and the seal rolls, are forced into contact with the seal rolls by the pressurized air. Further the flow of pressurized air collides with the internal pressure medium of the steamer within the cylindrical duct preventing the exhaust of the internal pressure medium through the cylindrical duct.

  • Patent number: 4089194
    Abstract: In a pressure seal apparatus for a high pressure steamer, seal rolls form a nip in a roll seal mechanism mounted on the fiber products feed in and take out openings of a high pressure steamer vessel body. The roll seal mechanisms shield the inside of the vessel from external air when fiber products are fed in or taken out and are positioned on the upper planes of a seal block through which a fiber products passage extends. Different members can be combined with the seal rolls in forming the seal mechanism, such as intermediate rolls formed as water permeable hoses are inserted into concave parts provided on opposite sides of the fiber products passage through the seal block. In another embodiment an elastic sealing member is placed in contact with the seal block and the seal rolls. In still another embodiment a shielding valve is provided at one end of the fiber products passage for regulating vessel internal pressure and preventing sudden pressure leakage.

  • Patent number: 4064582
    Abstract: A pressure sealing method for sealing the inlet and outlet parts of a high pressure steamer which performs steaming with saturated steam of high temperature and high pressure in processing a textile product for desizing, scouring, bleaching, dyeing or the like. A pair or more than one pair of air pressure chambers made of a gas or fluid exudative material formed in a hollow cylindrical or semicylindrical shape or made of a gas impermeable thin plate are arranged to confront one another at the inlet or outlet part in the high steamer for the entry or exit of the treated product. The pressure of a pressure chamber of the steamer and that of atmospheric parts are shut off by one pair or more than one pair of nipping faces of these air pressure chambers which are pressed against one another. The treated product is allowed to pass through the inlet and outlet parts against the combined pressure developed between the nipping faces.
