Definitions

  • the invention relates to an apparatus for the wet spinning of synthetic fiber, and more particularly to an apparatus for passing synthetic fiber material from the spinning nozzle through the various baths of treating liquid employed to set or harden the fiber by chemical and physical processes, and hereinafter generally referred to as spinning baths and spinning liquids.
  • Another object is the provision of transporting means for passing the fiber material through the spinning bath or baths without tensioning the fiber material.
  • Yet another object is the maintenance of such conditions in the spinning bath that the individual filaments of each group of filaments emit-ted from a spinning nozzle be uniformly wetted for reaction with the spinning bath.
  • a further object is the provision of rapid flow of the bath liquid relative to the fiber material without any tensioning of the latter.
  • the invention contemplates introducing the fiber material into a bath of spinning liquid, generating a flow of spinning liquid in the bath in one direction toward an endless, continuously movable support so as to urge the fiber material against the support, and moving the support through the bath so as to move the fiber material relative to the bath without tensioning.
  • Transportation means are continuously movable in the container for transporting the material through the liquid without tensioning it. Additional means are provided for withdrawing the material from the container.
  • FIG. 1 is a view in elevational longitudinal section of a wet spinning apparatus embodying a preferred embodiment of the device of the invention
  • FIG. 2 is a sectional elevational view of one of the elements of the apparatus of FIG. 1;
  • FIG. 3 shows a side elevation of the device of FIG. 2.
  • the apparatus includes two tanks 1 and 2, to which spinning liquids are fed through perforated feed pipes 1 and 2' respectively.
  • a constant level of treating liquid is maintained in the tanks by means of overflow arrangements which discharge liquid continuously into overflow troughs 1" and 2" respectively.
  • a plurality of spinning nozzles 3 only one of which is visible in FIG. 1 is arranged in tank 1 and axially aligned relative to a hollow drum 4 which is rotatably supported in the tank 1. It is mounted on a shaft 30 which is driven by a suitable prime mover such as an electric motor for rotation in the direction of the arrow.
  • a suitable prime mover such as an electric motor for rotation in the direction of the arrow.
  • the fiber material 5 which is deposited on the curved surface of drum 4 by nozzle 3 is carried by the drum through substantially a complete turn of the drum. Since the overflow is arranged at such a level as to keep the drum 4 completely submersed, the fiber material 5 is exposed to the chemical and physical action of the spin ning solution during its travel. There is no relative movement of fiber material and drum surface so that the material is not subjected to tensile stresses in the initial stages of the setting process.
  • FIG. 2 represents an elevational sectional view of the tank 1 through the axis of shaft 25.
  • the shaft has a free end to carry a pulley or other connecting means for driving connection with a prime mover and is journalled in a stationary member of the equipment. It enters tank 1 through a stuffing box 26 in substantially fluid-tight manner. It is axially secured to flat end wall 7 of drum 4. The center of the end wall 7 and the adjacent portion of shaft 25 are provided with an axial cylindrical bore 27 the purpose of which will become apparent promptly.
  • the other end wall 28 of drum 4 is formed with an axial opening and is rotatably movable on a short length of pipe 8 which passes in fluid-tight engagement through the wall of tank 1 into a pump chamber 9 in which a centrifugal pump 11, driven by electric motor 10, is ar ranged in such a manner that its axial suction opening communicates with pipe 8 and liquid is drawn through the pipe from the interior of drum 4 by pump 11 and discharged into the pumping chamber 9 from which it returns into the tank 1 through several ports 18, one of which only is shown in FIG. 2.
  • the cylindrical wall 6 of drum 4 is perforated. The openings in wall 6 are spaced in a substantially regular pattern and permit continuous flow of spinning liquid from tank 1 into the interior of drum 4 when pump 11 is driven by motor 10.
  • drum 4 If it is desired to operate drum 4 in a partly submersed condition, air could be drawn through the perforations of drum wall 6 above liquid level. prevent suificient negative pressure to be developed inside drum 4 to cause a satisfactory inward flow of spinning liquid.
  • Such operating conditions are illustrated in the second spinning bath of FIG. 1 in which the drum 4' partly projects above the top surface of the liquid.
  • Drum 4 is equipped in the same manner as drum 4 shown in FIG. 2.
  • the drum is equipped with an internal shield 12 fixedly mounted on pipe 8 and rotatably supported in axial cavity 27 of shaft 30.
  • the shield 12 is of cylindrical shape and snugly fits the inside of the cylindrical wall 6 of drum 4. It extends circumferentially over and beyond that portion of wall 6 which emerges from the spinning liquid.
  • Shield 12 may also be arranged in such a manner as to prevent or reduce inward flow of liquid through the perforations in cylindrical wall 6 where this may be desired in order either to increase inward flow in other surface portions or to selectively reduce or cancel the suction force caused by the radially inward flow of liquid through the perforatlons.
  • the diameter of hollow drums 4 and 4' is only slightly smaller than the length of the tanks so that the drums which extend substantially over the full width of the tank, as seen in FIG. 2, almost completely fill the tanks.
  • Heat transfer elements 29 and 29' are provided along the walls of the tanks to maintain the temperature of the spinning liquids at a predetermined value.
  • a transfer cylinder 13 tangentially cooperates with drum 4 to guide the fiber material from the perforated surface of drum 4 and out of tank 1.
  • Cylinder 13 is in circumferential engagement with one cylinder of a pair of pinch cylinders 14 and 15 between which the fiber material may be squeezed.
  • Another transfer cylinder 13' in circumferential contact with pinch cylinder 14 guides fiber material 5 towards the perforated surface of drum 4' in the second spinning bath in tank 2.
  • the cylinders 13, 13, 14 and 15 are suitably driven.
  • a driven transfer cylinder 13" withdraws the fiber material 5 from the surface of drum 4 after passage through the liquid bath in tank 2 and transfers it to a second set of pinch cylinders 14' and 15' from which it is further passed to driven sets of guide and stretch cylinders 16 and 17 which transport the fiber material, which now is completely solidified, to a cutting device in which the continuous filaments may be severed into pieces of suitable length for spinning on conventional mechanical spinning equipment.
  • Nozzles 3 and transfer cylinders 13, 13' and 13 are arranged closely adjacent to each other along the circumference of drums 4 and 4' respectively, so that the fiber material 5 is caused to travel over substantially a full turn of the drum in the respective tanks 1 and 2.
  • the nozzles 3 are mounted at the ends of tubes 19 which carry filters 20 and receive liquid spinnable fiber material from individual pumps 23 which are connected by a manifold to suitable storage means (not shown).
  • the nozzles 3 and their coordinated carrying tubes 19 and pumps 23 are individually pivotally supported in a frame 21, and a plurality of nozzles 3 may be pivoted towards and away from the surface of drum 4 by means of levers 22. When in their position adjacent drum 4, the nozzles are secured by engagement of filters 20 in resilient clips 24 mounted on the upper rim of a wall of tank 1.
  • Tanks 1 and 2 are filled with spinning liquids to the desired level determined by the respective overflow arrangements and pumps 11 of drums 4 and 4' are started to circulate the respective liquids inwardly through the perforations in the cylindrical surfaces of the drum and back into the tanks through ports 18. Synchronized rotation of the drums and cylinders is started.
  • Liquid fiber material is extruded through nozzles 3 by the pressure generated in pumps 23.
  • the extruded material reacts with the spinning liquid in tank 1 so as to gradually solidify.
  • the solidifying fiber material reaches the endless, continuously moving cylindrical surface of drum 4 and is held against the surface by the suction effect of the spinning liquid inwardly flowing through the perforations of the drum.
  • the fiber material thus is transported through the liquid while in stationary contact with the drum surface over substantially a full turn of the drum.
  • the liquid in tank 1 the liquid is acted upon by a rapidly flowing stream of spinning liquid which rushes past the fiber material through the perforation in the drum 4.
  • Threading of the apparatus then continues in an analogous fashion by passage of the leading ends of the filaments between cylinders 14, 15" and through the cylinder sets 16 and 17 to the cutting device. It will be readily appreciated that this arrangement saves time and labor as compared to the threading of a type of spinning bath now commonly in use.
  • the arrangement of the several transport and guide means of the inventive apparatus provides for tangential transfer of the fiber material between the various means without abrupt changes in the direction of travel of the material so as to avoid tensioning inherent in such changes. While immersed in the spinning liquids, the fiber material is effectively secured against any longitudinal tension while in intimate contact with a vigorously moving spinning liquid.
  • a container adapted to contain a spinning bath; a plurality of spinning nozzles in said container for releasing fiber material into said container for treatment in said spinning bath; a hollow drum supported for rotation in said container, said drum being formed with a plurality of openings in the curved surface thereof for providing communication between the container outside said drum and the inside of said drum; shielding means adjustably secured to said container closely adiacent a portion of said openings in the curved surface of said drum for selectively obstructing portions of said openings as said surface moves relative to said shielding means; suction means communicating with the inside of said drum for continuously withdrawing fluid therefrom and for feeding said fluid back into said container, whereby said fiber material is urged against the curved surface of said drum by the flow of fluid through said openings to be held by suction thereon while being subjected to intensified treatment by said fluid, said drum being located in said container for a portion of said curved surface to be continuously movable in said container between an area closely adjacent said
