Definitions

  • ABSTRACT OF THE DISCLOSURE A method of treating elongated textile material in a treatment vessel which has double walls, the inner wall being perforated; the treatment vessel having conical (or pyramidal) inlet and outlet sides, textile material being introduced at the inlet and removed, by suction, at the outlet side; the inner walls of the vessel are perforated, and treatment liquid introduced therein is removed alternately from one opposite lateral side, or the other, to set up cross currents of flow and bunch textile material, totally immersed in treatment liquid in the vessel; the removed liquid is re-introduced adjacent a portion of the outlet side by an injector nozzle, to additionally create a flow of liquid through a transport system which may be open, or closed.
  • the present invention relates to a method, and to an apparatus for liquid treatment of textile material which is in elongated form, for example textile webs, textile strands, cables, ropes, ribbons, tapes, or the like, and more particularly to a method for such treatment, and to an apparatus in which the treatment is carried out by immersing the textile material into the liquid retained Within a treatment vessel, from which the textile material is again removed after a predetermined treatment period.
  • Textile treatment arrangements are known in which the textile material is introduced from below into a treatment vessel by means of a liquid current which carries the textile material along, so that a certain section, or region, of the textile material will travel upwardly into the treatment vessel, where it is lifted above the level of the treatment liquid, by the pressure of the moving liquid, in order to be removed over rollers, or the like.
  • the vessel is formed with an injector nozzle at the inlet side of the textile material, so that treatment liquid which is injected will impinge on the textile material to move it into the treatment vessel.
  • the treatment liquid which is injected at that point can be removed from the vessel at a distant point, to form a closed liquid circuit.
  • Such an arrangement requires a mechanical removing device, such as a roller, which is undesirable for certain very fine textile materials, and further exposes the removed textile material to air, which is undesirable if further treatment of the textile material in an additional vessel may have to be carried out.
  • a curved tube is located in the treatment vessel, extending above the normal level of the liquid, through which the textile material is introduced.
  • the textile material leaves the curved tube, it is deflected at the lower part by the treatment vessel, and again guided to an injector by a stream of treatment liquid.
  • Such an arrangement may be used even with elevated temperatures, for example above 100 C.
  • the treatment vessel need not be completely filled with liquid, so that,
  • a treatment vessel may be shaped in a U-form, connected to the suction side of a pump at the bend of the U, the pressure side of the pump being connected to a collection vessel located at the upper end of the U-shaped treatment vessel.
  • the textile material while passing through the U-shaped vessel, is bunched together, thus increasing the capacity of the arrangement.
  • the textile material is removed from this vessel again by rollers; it is difficult to increase the pressure within the container above atmospheric.
  • the material is to be bunched within the treatment vessel so that any longitudinal stresses on elongated textile material are avoided, and treatment by the liquid will be uniform.
  • a closed vessel which is completely filled with treatment liquid, the vessel having inlet and outlet ends, preferably tapering in conical, or pyramidal form to material inlets and outlets shaped somewhat like the material to be treated, that is, for example, having longitudinal slits or circular openings, or the like.
  • a material treatment path in the form, for example, of a closed tube which is re-connected to the inlet, is connected to the outlet side of the vessel; interposed between the transport path and the outlet is an injection nozzle, through which a stream of liquid can be directed against the textile material to carry it along through the transport path.
  • a cross-current of treatment liquid, transverse to the direction of the textile material from inlet, to outlet side is caused to arise adjacent the inlet side of the vessel, for example by providing perforated openings close to the inlet side, and at opposite transverse sides of the vessel, from which liquid is alternately removed by a suction pump.
  • This same liquid is then re-introduced into the closed circuit at the injection nozzle at the outlet. Removal of liquid, alternately, from one side or the other across the treatment tank will cause the material to bunch, or fold in accordion shape, thus increasing the amount of material within the treatment vessel and the passage of time of any given section of material through the treatment vessel.
  • the treatment vessel may be connected, in series, or in parallel with other similar treatment vessels, with injection nozzles provided at suitable intervals to carry the material along.
  • a closed loop is provided, the material being introduced by means of a leader into the treatment system, which leader is then connected to the trailing end of the material so that an endless loop of material to be treated can travel around the liquid circuit including the treatment chamber.
  • the apparatus of the present invention is useful for treatment of textured mesh, or net material of polyester fiber, in which stabilization of the mesh, or net structure is required; in the dyeing art, and particularly in connection with dyes which may have the tendency to fold: in bleaching, or in any other textile treatment step desired.
  • Control of the speed of travel, or the extent of folding, or bunching of the textile material can readily be obtained by adjusting the intensity of the stream of liquid removed,.or injected; the intensity of treatment .can likewise be adjusted by additionally providing cross currents of treatment liquid within the treatment vessel, that is currents transverse to the direction of travel of the texile material, for example by additional reversing pumps, pumps with reversing valves, or the like.
  • liquid removed from one side of the vessel can be reintroduced at the other, or liquid removed from the inletcan be reintroduced at other points of the vessel or in the injectors in the transport path.

  • -Textile material for example in form of a closed loop, is transported over transport path 4 to the inlet 2 of vessel 1.
  • Pump 22 constantly removes liquid, by suction, while the switch-over valve 21 changes the side at which liquid is removed, so that a suction current will arise within the vessel, periodically changing from one side of the vessel towards the other.
  • This periodically changing stream indicated in FIG. 8 schematically by arrows 29a has a component transverse to the general direction of travel of the textile material 5.

  • the pressure stream (arrows 31) is primarily desirable to prevent adhesion of the textile material against the walls of the vessel adjacent the outlet 3, and to ensure proper placement of the textile material into the outlet and then into the transport path. A further portion of the liquid will take the path indicated by arrows 32, in a direction counter to the direction of travel of the textile material 5. This stream contributes to the pleating and bunching of the textile material and thus to increase the intensity of treatment.
