Definitions

  • the present invention relates to a melt spinning apparatus, and more specifically, to a melt spinning apparatus that can execute spinning so as to obtain notably a very fine multifilament yarn that is uniform and that has an even fineness.
  • a molten polymer is supplied by an extruder to spinning packs and spun out of a spinneret of the spinning packs as filaments. Cooling winds are then blown against the filaments to solidify them to obtain a multifilament yarn.
  • the more filaments are spun out the more difficult it is to uniformly cool each of the filaments in a longitudinal direction. Then, the cooling may be uneven, the filaments may come into contact with each other below the spinneret, or the fineness may be uneven.
  • each filament is likely to have a high internal strain and to be affected by associated air currents or cooling winds, resulting in an uneven fineness.
  • the number of filaments constituting the multifilament yarn is twice to five times as large as that of filaments constituting a common yarn. Consequently, the above tendency is more prone to occur.
  • a known effective method for uniformly cooling melt spinning filaments comprises arranging cylindrical spin cooling cylinders below respective spinning packs and blowing cooling winds into the spin cooling cylinders from their top portions so that the winds flow parallel with the filaments (for example, International Publication No. WO 99/067450A). It is known that if the spin cooling cylinders are thus used for cooling, a certain method can be very effectively used to make the cooling action more uniform particularly if very fine filaments are subjected to melt spinning. This method comprises using packing to seal the upper end of each of the spin cooling cylinders from the corresponding spinning pack so that cooling winds from the spin cooling cylinder will not flow in the adjacent pack, as described in the International Publication No.WO 01/79594A.
  • each spinning pack is constructed by assembling a plurality of parts together, so that when the spinning packs are installed, the positions of their lower ends vary unavoidably because of errors in the manufacture of these parts or a variation in the amount of collapse of seal elements during assembly and mounting, the seal elements belonging to the spinning packs.
  • each spin cooling cylinder may be imperfect. Further, cooling winds from the adjacent spin cooling cylinder may flow in to cause uneven cooling. This effect is likely to be produced particularly if the cooling section is provided with an integral cooling wind supply box that cover the plurality of spinning packs and if the filament spinning cylinders are provided inside the cooling wind supply box in association with the respective spinning packs.
  • the present invention provides a melt spinning apparatus comprising a plurality of spinning packs installed in a pack housing contained in a spinning beam, the spinning packs being arranged in a line, an integral Quenching stack provided below the plurality of spinning packs so as to be shared by the spinning packs, and filament cooling cylinders each comprising a cylindrical filter and provided inside the Quenching stack in association with the respective spinning packs, the apparatus being characterized in that a first seal mechanism is used to seal a top portion and a bottom portion of each of the filament cooling cylinders from a top plate and a bottom plate, respectively, of the Quenching stack, and a second seal mechanism is used to seal the top portion of the filament cooling cylinder from a bottom surface of the pack housing via a spacer.
  • the first seal mechanism is used to seal the top portion and bottom portion of each of the filament cooling cylinders from the top plate and bottom plate, respectively, of the Quenching stack
  • the second seal mechanism is used to seal the top portion of the filament cooling cylinder from the bottom surface of the pack housing via the spacer. Accordingly, it is possible to allow only stable cooling winds having passed through the filament cooling cylinders to flow into uniformly cool spun-out filaments. Further, since the second seal mechanism is used to seal the top portion of the filament cooling cylinder from the bottom surface of the pack housing, not from the spinning pack, the spun-out filaments can be reliably uniformly cooled without any seal leakage even if the mounting heights of the spinning packs are changed as a result of the replacement of the packs.
  • thermoplastic polymer applied to a melt spinning apparatus according to the present invention is not particularly limited. Any thermoplastic polymer is available for the melt spinning apparatus provided that it can be used to form fibers.
  • the thermoplastic polymer includes, for example, polyamide, polyester, or polyolefin.
  • the melt spinning apparatus can execute spinning so as to obtain a uniform multifilament yarn regardless of the single filament fineness of spun-out filaments.
  • the melt spinning apparatus is particularly effective on the melt spinning of a multifilament yarn of single filament fineness at most 0.55 dtex or even at most 0.33 dtex.
  • the melt spinning apparatus is very effective on the melt spinning of a very fine multifilament yarn having such a small filament yarn fineness and containing at least 90 filaments in total.
  • a pack housing 33 is provided in an upper spinning beam 1.
  • a plurality of spinning packs 2 are housed inside the pack housing 33 so as to be arranged in a direction orthogonal to the sheet of the drawing.
  • a spinneret 3 is incorporated into each of the spinning packs 2 and has an exposed bottom surface.
  • a plurality of pack housings 33 may be formed for the respective spinning packs 2 or an integral pack housing 33 may comprise a plurality of installation holes in which the respective spinning packs can be installed.
  • a filament cooling device 6 is provided below the spinning packs 2 installed in the pack housing 33 as described above.
  • the filament cooling device 6 blows cooling winds against filaments Y constituting the multifilament yarn at 20 to 50 mm below a bottom surface of each of the spinnerets 3.
  • the filament cooling device 6 has independent filament cooling cylinders 44 for the respective spinning packs 2 so that each of the cooling cylinders 44 surrounds the filaments Y spun out of the spinning pack 2 through the spinneret 3.
  • the filament cooling cylinders 44 are installed in a cooling wind supply box 15.
  • the cooling wind supply box 15 is integrally formed so as to be shared by the plurality of spinning packs 2.
  • the independent filament cooling cylinders 44 are provided inside the outer cooling wind supply box 15 for the respective spinning packs 2 (see Figure 3).
  • each of the filament cooling cylinders 44 has a double structure composed of an inner cylindrical filter 8 and an outer cylindrical filter 9, as shown Figure 5.
  • a heat insulating member 24 composed of an adiabatic material is provided between a top plate 6b of the cooling wind supply box 15 and a bottom surface of the pack housing 33 so as to surround the installation holes in the spinning packs 2.
  • the heat insulating member 24 maintains a bottom surface of each of the spinnerets 3 at an appropriate temperature for melt spinning.
  • a protective cover 12 for the filament Y is separably connected to a bottom surface of each filament cooling cylinder 44.
  • An oiling device 11 is provided in a lower part of the protective cover 12 so as to apply a lubricant to the filaments Y cooled by cooling winds through the filament cooling cylinder 44.
  • a winding device is provided downstream of the oiling device 11 via a godet roller for drawing the filaments Y (not shown in the drawings).
  • pieces of packing 21, 22 are provided as a first seal mechanism, a piece of packing 21 is provided between a top surface of each filament cooling cylinder 44 and a top plate 6b of the cooling wind supply box 15, and a piece of packing 22 is provided between a bottom surface of each filament cooling cylinder 44 and a bottom plate 6c of the cooling wind supply box 15.
  • the filament cooling cylinder 44 is thus sealed from the top plate 6b and bottom plate 6c of the cooling wind supply box 15.
  • the first seal mechanism forms a seal to prevent the flow, into a filament path 27, of the cooling winds other than those passing through the cylindrical filters 8, 9 of the filament cooling cylinder 44.
  • a seal plate 5 as a spacer is placed on the top plate 6b of the cooling wind supply box 15 via packing 39.
  • the seal plate 5 partly overlaps the packing 21 at the top of the filament cooling cylinder 44 and has its top surface sealed from the bottom surface of the pack housing 33 using packing 20 as a second seal mechanism.
  • the second seal mechanism forms a seal to hinder external cooling winds from flowing into the filament path extending from the top portion of the filament cooling cylinder 44 to the bottom surface of the pack housing 33. This prevents the disturbance of the filament Y passing through a downstream side of the filament cooling cylinder 44.
  • the top portion of the filament cooling cylinder 44 is sealed from the bottom surface of the pack housing 33, not from the corresponding spinning pack 2. Accordingly, even if the mounting height of the spinning pack 2 is changed as a result of, for example, the replacement of the spinning pack, it is possible to prevent the seal leakage between the top portion of the filament cooling cylinder 44 and the bottom surface of the pack housing 33.
  • the seal plate 5, inserted as a spacer as described above, has its thickness varied to set the appropriate distance from the bottom surface of each spinneret 3 to a cooling wind blowout start position of the filament cooling cylinder 44.
  • the distance from the bottom surface of each spinneret 3 to the cooling wind blowout start position of the filament cooling cylinder 44 is not particularly limited but is preferably selected in accordance with the single filament fineness. This distance is preferably between 20 and 50 mm, more preferably between 30 and 40 mm for the spinning of a very fine filament.
  • the illustrated filament cooling device 6 has an elevating and lowering device 13 provided on a rear surface of the protective cover 12 and driven by a hydraulic cylinder.
  • the elevating and lowering device 13 enables the filament cooling device 6 to be elevated and lowered via the protective cover 12. After the filament cooling device 6 has been lowered, the spinning packs 2 can be replaced with new ones or the spinnerets 3 can be cleaned. Further, since the filament cooling device 6 can be elevated and lowered for all of the plurality of spinning packs 2, the airtight sealing characteristic of the yarn cooling device 6 is further enhanced.
  • the cooling wind supply box 15 of the filament cooling device 6 is connected to a cooling wind supply duct 26 via a duct 32.
  • a porous piece 7 such as the one shown in Figure 6 is incorporated into the connection between the cooling wind supply duct 26 and the duct 32.
  • the porous piece 7 serves to make the air flow of cooling winds and their static pressure uniform to allow the cooling winds to be uniformly distributed to the filament cooling cylinders 44 in the cooling wind supply box 15 (see Figure 3).
  • the porous piece 7 preferably has an open area ratio of 30 to 50% and is composed of a material having a transmission resistant characteristic or a combination of the material.
  • the material is a wire mesh, a non-woven cloth, or a porous plate such as a corrosion-resistance metal and plastics.
  • An air flow regulating device 14 and an expansion joint 17 are incorporated into the cooling wind supply duct 26.
  • the air flow regulating device 14 properly adjusts the air flow to the filament cooling device 6.
  • the expansion joint 17 allows the elevating and lowering device 13 to smoothly perform operations of elevating and lowering the filament cooling device 6.
  • the plurality of filament cooling cylinders 44 may be arranged in a line as shown in Figure 3.
  • the filament cooling cylinders 44 may be staggered as shown in Figure 4 in association with the staggered arrangement of the spinning packs 2 (spinnerets 3) with respect to the spinning beam 1. The staggered arrangement makes the melt spinning apparatus compact.
  • the number of filament cooling cylinders 44 in the integral cooling wind supply box 15 can be arbitrarily set and may be, for example, 4, 6, 8, 10, 12, 14, 16.
  • the outer cylindrical filter 9 may be formed of a porous plate of open area ratio 5 to 8%, while the inner cylindrical filter 8 may be formed of a porous filter having a lower open area ratio than the outer cylindrical filter 9.
  • the cylindrical filters 8, 9, constituting the filament cooling cylinder 44 are preferably set to have a cooling wind blowout length of 80 to 100 mm when incorporated into the cooling wind supply box 15.
  • the filament cooling cylinder 44 is preferably set to have a passing resistance ⁇ P/Q of 0.02 to 0.06.
  • a wire mesh or a non-woven cloth may be incorporate between the inner cylindrical filter 8 and the outer cyrindrical filter 9.
  • Figure 7 shows essential parts of another embodiment of a melt spinning apparatus according to the present invention.
  • the seal plate 5 is placed on the packing 21 at the top of the filament cooling cylinder 44, with the packing 20 placed on the top surface of the seal plate 5.
  • the present embodiment differs from the above embodiment in that the packing 20 is not allowed to adhere directly to the bottom surface of the pack housing 33 but in that a firm seal is formed by using a seal ring 35 having an annular projecting portion 35a which projects downward and which cuts into the surface of the packing 20.
  • the seal ring 35 also acts as a spacer.
  • the seal ring 35 is formed on the bottom surface of the pack housing 33 so as to surround the installation hole in the spinning pack 2.
  • the seal ring 35 is removably screwed into the bottom surface of the pack housing 33.
  • the projecting portion 35a can be allowed to cut into the surface of the packing 20 by using the elevating and lowering device 13 to raise the protective cover 12.
  • Figure 8 shows essential parts of another embodiment of a melt spinning apparatus according to the present invention.
  • the seal ring 35 having the annular projecting portion 35a projecting downward, is removably screwed into the bottom surface of the pack housing 33 as in the case of Figure 7.
  • the seal ring 35 acts as a spacer.
  • the seal plate 5, placed on the packing 21 at the top of the filament cooling cylinder 44 in Figure 7, is replaced with an annular pot 37 in the embodiment shown in Figure 8.
  • the pot 37 is filled with a fluid metal 43 acting as a seal material. Then, a seal is formed by immersing the annular projecting portion 35a of the seal ring 35 into the liquid metal 43.
  • the applicable liquid metal include a low-temperature solder, a fuse, or a low-melting-point material used in a fire hydrant, a high pressure reservoir safety plug, a dental material, a physical or chemical model, or the like.

  • Figure 9 shows essential parts of another embodiment of a melt spinning apparatus according to the present invention.
  • the spinning pack 2 is installed so that its bottom portion projects below the bottom surface of the pack housing 33. Since the bottom portion of the spinning pack 2 thus projects downward, a heater 4 is set around the projecting portion so as to maintain the surface temperature of the spinneret 3 at a predetermined value (spinning temperature ⁇ the predetermined value ⁇ spinning temperature-10°C).
  • the heater 4 is fixed to the bottom surface of the pack housing 33 via adiabatic packing 19.
  • the packing 20 and seal ring 5, which are similar to those in the embodiment shown in Figures 1 and 2, are abutted against the bottom surface of the heater 4.
