Definitions

  • each exhaust hole By making the area of each exhaust hole be equal to or smaller than 30mm 2 so as to increase passage resistance of each exhaust hole, it was possible to suppress suction of gas in a concentrated manner through exhaust holes at a position where gas easily flowed, such as exhaust holes arranged at a position which was relatively close to the suction device in a suction direction of gas. That is, by making passage resistance of each exhaust hole higher, gas was likely to be sucked evenly through each exhaust hole, and concentration of an air flow inside an exhaust ring to one or some of exhaust holes was restrained, with the result that disturbance of air flow inside the exhaust ring could be suppressed.
  • Suction quantity of gas per unit time may need to be changed by changing the total area of the exhaust holes, depending on the thickness or types of yarns to be spun out.
  • each exhaust hole can be closed by using a typical pin or the like.
  • each of the exhaust holes can be closed by using typical screws or the like. That is, the total area of the exhaust holes is changeable by increasing or decreasing the number of pins, screws, or the like which close the exhaust holes.
  • the melt spinning device of any one of the first to sixth aspects is arranged such that the spinning unit is capable of spinning out filaments whose thickness is 0.55 dtex per filament (0.5DPF) or less.
  • the melt spinning device of any one of the first to seventh aspects is arranged such that the enclosure member comprises: a passage reduction part whose passage width is arranged to be narrowed toward the downstream side in a suction direction in which the gas is sucked; a linear part whose passage width is constant, and which is arranged on the suction device side of the passage reduction part, in the suction direction; and a curved part which is disposed between the passage reduction part and the linear part, and has a curved passage.
  • a spinneret 13 in which nozzles 14 are formed is provided at a lower end portion of each of the spinning packs 12.
  • the spinning packs 12 spin out molten polymer as filaments f from each of the nozzles 14 of the spinneret 13.
  • one multi-filament yarn (yarn Y) formed of plural filaments f is spun out from one spinneret 13.
  • aperture area of each of the nozzles 14 is, for example, 0.017mm 2 ( ⁇ 0.15) to 0.07mm 2 ( ⁇ 0.30), and the spinning beam 2 can spin filaments f which are thinner than 0.55 dtex per filament (0.5DPF) or less.
  • the oil guide 5 is configured to supply a yarn Y with oil.
  • the oil guide 5 is provided below the cooling cylinders 21 and partitioning cylinders 22.
  • the yarn Y having been cooled in the cooling cylinder 21 comes into contact with the oil guide 5.
  • the oil guide 5 discharges oil to the yarn Y so that the oil is applied to the yarn Y.
  • the yarn Y to which the oil has been applied by the oil guide 5 is taken up by a take-up roller (not illustrated) provided below the oil guide 5.
  • the yarn Y is then sent to a winding device (not illustrated) and is wound onto a bobbin (not illustrated) at the winding device.
  • the enclosure member 31 is divided into one first member 31a which is a rear part of the enclosure member 31 (upstream side in the direction where gas is sucked) and two second members 31b which are arranged in front of the first member 31a (downstream side in the suction direction). (See FIGs. 3 to 5 , and note that the details will be described later.)
  • the curved part 62 is provided between the passage reduction part 61 and the linear part 63 in the suction direction.
  • the inner wall surface 64 of the curved part 62 (see bold lines in FIG. 5 ) is curved so that the passage width is narrowed toward the suction pump 34.
  • the linear part 63 is arranged on the downstream side of the passage reduction part 61 and the curved part 62 in the suction direction, and the passage width of this part is constant.
  • the front end portion of the linear part 63 is connected to the duct 33. Gas tends to flow smoothly along the inner wall surface 64 of the curved part 62, when flowing from the passage reduction part 61 to the linear part 63. Therefore, problems such as generation of vortexes by separation of air flow are suppressed.
  • the value of dispersion between rings is large in such cases where suction quantity of gas in one or some of exhaust rings 32 is large/small as compared to the other exhaust rings 32 (that is, the degree of sway of yarns and the like tends to be different between the exhaust rings 32, and, as a result, the quality of yarns tends to be inconsistent).
  • the value of dispersion between rings is small, as compared to cases where the value is large, it is suggested that gas is evenly sucked from the exhaust rings 32.
  • each exhaust hole 72 it is necessary to arrange the area of each exhaust hole 72 to be at least approximately 30 mm 2 or less in order to increase the resistance of each exhaust hole 72. More preferably, by setting the area of each exhaust hole 72 at approximately 13 mm 2 or less to further increase the resistance of each exhaust hole 72, it is possible to make dispersion in ring and dispersion between rings small.
  • the present inventors interpreted the above result, as follows. Since exhaust holes 72 of each exhaust ring 32 were arranged at equal intervals, gas tended to be discharged evenly in the circumferential direction of each exhaust ring 32. Because the flow rate of gas around each exhaust ring 32 was close to even, flow rate dispersion in the whole internal space 44 of the enclosure member 31 could be reduced, as compared to cases where the flow rate around each exhaust ring 32 dispersed greatly. Thus, it was considered that dispersion of suction quantity of gas between exhaust rings 32 could be suppressed. Based on the above, to reduce dispersion between rings, it is preferable to arrange exhaust holes 72 at equal intervals in the circumferential direction of an exhaust ring 32.
  • each exhaust hole 72 By making the area of each exhaust hole 72 be equal to or smaller than 30mm 2 so as to increase passage resistance of the exhaust hole 72, it is possible to suppress drastic discharge of gas and sucking of gas in a concentrated manner through an exhaust hole 72 at a position where gas easily flows. That is, by making the resistance of each exhaust hole 72 bigger, gas is likely to be sucked evenly through each exhaust hole 72, and to suppress concentration of the air flow to one or some of the exhaust holes 72 inside the exhaust ring 32. Furthermore, by arranging the opening ratio to be equal to or lower than 2.5%, it is possible to suppress suction quantity of gas per unit time from being excessively large relative to the capacity of the internal space of an exhaust ring, with the result that disturbance of air flow inside the exhaust ring 32 can be suppressed.
  • a gas passage may be clogged when monomer gas solidifies at around the curved part 62 and the linear part 63.
  • the arrangement in which the enclosure member 31 is divided and the second member 31b is attachable to and detachable from the first member 31a is very effective for restraining the clogging of the passage.
