Definitions

  • the present invention relates to a combined yarn producing device which is configured to produce a combined yarn by combining two types of yarns.
  • a combined yarn formed by combining two types of yarns which are different in physical properties or the like has been known.
  • a representative example of such a combined yarn is a differential-shrinkage combined yarn produced by combining two types of yarns which are different in thermal shrinkage.
  • a typical differential-shrinkage combined yarn is produced by combining, by air interlacing or the like, a thermally-treated yarn which is thermally treated (thermally set) after drawn and a non-thermally-treated yarn which is not thermally set after drawn.
  • differential-shrinkage combined yarns are produced by combining thermally-treated yarns and non-thermally-treated yarns which are produced independently. Later on, a technology of producing differential-shrinkage combined yarns simultaneously with drawing by using a drawing machine configured to draw material yarns such as undrawn yarns (UDY) and partially oriented yarns (POY) was developed (see, e.g., PTL 1 (Japanese Unexamined Patent Publication No. 57-193543 )).
  • FIG. 8 shows an example of a known device for producing differential-shrinkage combined yarns.
  • This device 100 is provided with a first roller 101 which is a heating roller, a second roller 102 which is a non-heating roller, a heater 103 provided between the first roller 101 and the second roller 102, a guide 104 provided to bypass the heater 103, and a combining section 105.
  • a differential-shrinkage combined yarn is produced by this device, to begin with, two packages Pa and Pb on each of which a material yarn such as the undrawn yarn (UDY) and the partially oriented yarn (POY) is wound are prepared.
  • the yarn Ya on one package Pa is arranged to run a yarn path which connects the first roller 101 with the second roller 102 via the heater 103.
  • the yarn Ya is heated to a drawable temperature at the first roller 101, and is then drawn between the first roller 101 and the second roller 102.
  • the yarn Ya is thermally treated by the heater 103.
  • the yarn Yb on the other package Pb is arranged to run on a yarn path which connects the first roller 101 with the second roller 102 via the guide 104.
  • the yarn Yb is heated to a drawable temperature at the first roller 101, and is then drawn between the first roller 101 and the second roller 102. Being different from the yarn Ya, the yarn Yb is not thermally treated during the drawing.
  • the yarn Ya thermally treated after drawn becomes a low-shrinkage yarn with low thermal shrinkage
  • the non-thermally-treated yarn Yb becomes a high-shrinkage yarn with high thermal shrinkage.
  • JP-H01-221505 A is related to the production of differently shrunk blended filaments using separate feed rollers for yarns spun out from separate spinning devices.
  • CN 101200826 A is related to a similar device, and JP 2013-204183 A belongs to the technological background.
  • packages of material yarns such as UDY and POY are prepared in advance, and two types of yarns different in thermal shrinkage are produced from the material yarns.
  • a combined yarn is produced through at least two steps including a step of producing the packages of the material yarns and a step of producing the two types of yarns from the packages and combining the yarns, and this requires a lot of labor and cost.
  • An object of the present invention is to provide a combined yarn producing device capable of serially performing processes from spinning to production of a combined yarn.
  • a combined yarn producing device includes: a yarn feed roller configured to feed yarns spun out from a spinning apparatus; a first drawing roller on which a first yarn among the yarns fed from the yarn feed roller is wound, the first drawing roller being configured to be higher in yarn feeding speed than the yarn feed roller and to heat and feed the first yarn drawn between the yarn feed roller and the first drawing roller; a second drawing roller on which a second yarn among the yarns fed from the yarn feed roller is wound, the second drawing roller being configured to be higher in yarn feeding speed than the yarn feed roller, to be lower in roller surface temperature than the first drawing roller, and to feed the second yarn drawn between the yarn feed roller and the second drawing roller; and a combining section configured to combine the first yarn fed from the first drawing roller and the second yarn fed from the second drawing roller.
  • the combined yarn producing device of the present invention includes the yarn feed roller configured to feed the yarns spun out from the spinning apparatus 2 and the two drawing rollers which are higher in the yarn feeding speed than the yarn feed roller.
  • the first yarn is drawn between the yarn feed roller and the first drawing roller whereas the second yarn is drawn between the yarn feed roller and the second drawing roller.
  • the second drawing roller is lower in the roller surface temperature than the first drawing roller.
  • the first yarn drawn by the first drawing roller is heated by a higher temperature than the second yarn is.
  • the first yarn and the second yarn after drawn are therefore different in physical properties such as thermal shrinkage. Thereafter, the first yarn and the second yarn are combined in the combining section and a combined yarn is produced.
  • two types of yarns which are different in physical properties are produced from yarns spun out from the spinning apparatus, and processes until the combination of the two types of the yarns are serially performed.
  • processes from the spinning to the production of the combined yarn are serially performed, labor and cost are significantly reduced as compared to known arrangements.
  • the combined yarn producing device of the first aspect is arranged such that the first drawing roller is a heating roller heating the first yarn wound onto a surface of the heating roller, and the second drawing roller is a non-heating roller not heating the second yarn wound onto a surface of the non-heating roller.
  • the first yarn drawn between the yarn feed roller and the first drawing roller is heated by the first drawing roller which is a heating roller.
  • the second yarn drawn between the yarn feed roller and the second drawing roller is wound onto the second drawing roller which is a non-heating roller, and hence the second yarn is not heated by the second drawing roller.
  • the combined yarn producing device of the first or second aspect is arranged such that the yarn feeding speed of the first drawing roller is higher than the yarn feeding speed of the second drawing roller.
  • the first yarn which is heated at a high temperature by the first drawing roller after drawn is a rigid yarn as compared to the second yarn.
  • a difference in the rigidity is one of reasons why the two types of yarns are not easily interlaced at the combining section.
  • the yarn feeding speed of the first drawing roller is higher than that of the second drawing roller, there is a difference in the yarn tension at the time of the combination, and hence the tension of the first yarn is lower than that of the second yarn. With this, the rigid first yarn becomes easily bendable, and the interlacing of the first yarn and the second yarn in the combining section is facilitated.
  • the difference in the tension between the first yarn and the second yarn at the time of the combination is preferably not excessively large.
  • a difference between the yarn feeding speed of the first drawing roller and the yarn feeding speed of the second drawing roller preferably falls within the range of 0.25% to 2.5% of the yarn feeding speed of the first drawing roller (the fourth aspect of the invention).
  • the combined yarn producing device of any one of the first to fourth aspects is arranged such that the first yarn is wound onto the first drawing roller at a winding angle of less than 360 degrees, and the second yarn is wound onto the second drawing roller at a winding angle of less than 360 degrees.
  • the winding angles of the first yarn and the second yarn on the drawing roller are both less than 360 degrees. In other words each yarn is wound not more than once on each drawing roller, and hence the yarn placement on each drawing roller is easily done.
  • the combined yarn producing device of any one of the first to fourth aspects is arranged such that the first drawing roller and the second drawing roller extend in a predetermined direction, the first yarn before wound onto the first drawing roller and the second yarn before wound onto the second drawing roller run side by side in the predetermined direction, the first yarn is wound onto the first drawing roller at a winding angle of less than 360 degrees, a separate roller is provided in the vicinity of the second drawing roller, and the second yarn is wound at least once between the second drawing roller and the separate roller.
  • the second drawing roller does not heat a yarn to a high temperature and hence this roller can be short in diameter.
  • the contact length with the second yarn is short and the gripping force is low.
  • the second yarn is wound at least once between the second drawing roller and the separate roller. The contact length between the second drawing roller and the second yarn is therefore long and the gripping force is increased, with the result that the second yarn is less likely to slip.
  • the first yarn and the second yarn are lined up in the roller axial direction.
  • the first yarn is wound onto the first drawing roller at a winding angle of less than 360 degrees, and hence the yarn path of the first yarn after wound onto the first drawing roller is unlikely to be shifted from the yarn path of the first yarn before wound onto the first drawing roller.
  • the second yarn is wound between the second drawing roller and the separate roller at least once, and hence the yarn path of the second yarn after wound onto the second drawing roller is shifted from the yarn path of the second yarn before wound onto the second drawing roller. This makes it possible to cause the yarn path of the first yarn fed by the first drawing roller and the yarn path of the second yarn fed by the second drawing roller to converge, immediately before reaching the combining section.

  • yarns Y (Y1 and Y2) made of synthetic fibers (e.g., polyester fibers) are spun out, respectively.
  • an oil guide 8 is provided below each spinneret 7, to apply oil to the spun-out yarns Y.
  • the combined yarn producing device 3 is provided with rollers 10 to 19 configured to take up the yarns Y on which the oil has been applied. While the rollers 10 to 19 take up the yarns Y, the combined yarn producing device 3 draws and thermally treats the yarns Y to produce two yarns Y1 and Y2 which are different in physical properties. Furthermore, a single combined yarn Ym is produced by combining the two yarns Y1 and Y2. The structure of the combined yarn producing device 3 will be detailed later.
  • the winding device 4 is configured to wind combined yarns Ym respectively produced by the combined yarn producing devices 3.
  • the winding device 4 includes members such as a bobbin holder 21 and a contact roller 22.
  • the bobbin holder 21 is long in the front-back direction (i.e., the direction orthogonal to the plane of FIG. 1 ) in shape, and is rotationally driven by an unillustrated motor.
  • bobbins 23 are attached to be lined up along the longitudinal direction of the bobbin holder 21.
  • the winding device 4 rotates the bobbin holder 21 so as to wind the combined yarns Ym onto the respective bobbins 23, with the result that packages 24 are formed.
  • the contact roller 22 adjusts the shape of each package 24 by making contact with the surface of each package 24 and applying predetermined contact pressure thereto.
  • the controller 5 is provided with a setting unit 25 for setting control parameters of various actions of the spun yarn take-up apparatus 1. Based on the parameters set by an operator through the setting unit 25, the controller 5 controls the sections of the combined yarn producing device 3 and the winding device 4. For example, the controller 5 controls the speed of a motor (not illustrated) by which the rollers 10 to 19 of the combined yarn producing device 3 are driven and the temperature of a heater 30 provide in each of the rollers 11 to 15.

  • the apparatus is not very large as compared to the known apparatuses because the diameter of the second drawing roller 16 can be short.
  • the yarn Y1 which is thermally set at a high temperature is a rigid yarn as compared to the yarn Y2 which is not thermally set.
  • Such a difference in the rigidity is one of reasons why the two types of the yarns Y1 and Y2 are not easily interlaced at the interlacing device 26.
  • the yarn feeding speeds V4 and V5 of the first drawing rollers 14 and 15 are higher than the yarn feeding speed V6 of the second drawing roller 16
  • the yarns Y1 and Y2 are different in the yarn tension at the time of the combination, and the tension of the yarn Y1 is lower than the tension of the yarn Y2.
  • the rigid yarn Y1 becomes easily bendable, and the interlacing of the two types of the yarns Y1 and Y 2 in the interlacing device 26 is facilitated.
  • the difference in the yarn tension between the two types of the yarns Y1 and Y2 at the time of the combination is preferably not excessively large.
  • the difference in the speed between the first drawing rollers 14 and 15 and the second drawing roller 16 is preferably 0.25% to 2.5% of the yarn feeding speeds V4 and V5 of the first drawing rollers 14 and 15.
  • the spun yarn take-up apparatus of the present embodiment can be used not only for producing the combined yarn Ym by combining the two types of the yarns Y1 and Y2 but also for producing only one type of yarns.
  • all of the yarns Y spun out from the spinnerets 7 of the spinning apparatus 2 are wound onto the two first drawing rollers 14 and 15, and no yarn Y is wound onto the second drawing roller 16.
  • all of the yarns Y are thermally set after drawn, so that only the yarns with low thermal shrinkage are produced.
  • all of the yarns Y spun out from the spinnerets 7 are wound onto the second drawing roller 16 and all of the yarns Y are not thermally set after drawn, only yarns with high thermal shrinkage are produced.
