  • the air spinning device 6 is capable of generating a swirling airflow inside the spinning chamber SC (see the hollow arrows shown in FIG. 3 ).
  • the spinning chamber SC is described in more detail below.
  • the spinning chamber SC is a space surrounded by the fiber guide 61, the spindle 62, and the nozzle block 63. More specifically, the spinning chamber SC is a space surrounded by the substantially conical spindle 62 that is inserted from one side relative to a substantially conical through hole 63p in the nozzle block 63 and the fiber guide 61 attached onto the other side of the nozzle block 63.
  • the shape of the through hole 63p is not limited to such a substantially conical shape as illustrated in FIG. 3 , and can be a substantially columnar shape or the like. Put another way, the shape of the through hole 63p is not limited to a specific shape and can be of any shape so long as a swirling airflow is favorably generated in the spinning chamber SC.
  • the spinning chamber SC is divided into a space SC1 provided between the fiber guide 61 and the spindle 62 and a space SC2 provided between the spindle 62 and the nozzle block 63.

  • the air spinning device 6 is configured without the needle 61n as shown in FIG. 4 , the same object and effect according to the present invention are achieved.
  • the scope of the present invention also encompasses such a modification.
  • the sliver F is caught at a downstream end portion of the fiber guide 61 and introduced into the fiber passageway 62s of the spindle 62.
  • the yarn-defect detecting device 7 detects a defect produced in the spun yarn Y.
  • the yarn-defect detecting device 7 includes a light source 71, a light-receiver 72, and a casing 73. Arrows shown in FIG. 5 indicate the direction of light emitted from the light source 71.
  • the light source 71 is a semiconductor device, or, put another way, a light-emitting diode, that emits light in response to application of forward voltage thereto.
  • the light source 71 is arranged so as to illuminate the spun yarn Y with the light emitted from the light source 71.
  • the light-receiver 72 is a semiconductor device, or, put another way, a phototransistor, that can control electric current with optical signals.
  • the light-receiver 72 is arranged so as to receive the light emitted from the light source 71.
  • the casing 73 is a member that holds the light source 71 and the light-receiver 72 at predetermined positions.
  • a yarn passage 73a, through which the spun yarn Y passes, is defined in the casing 73.
  • the casing 73 holds the light source 71 and the light-receiver 72 such that the light source 71 and the light-receiver 72 face each other with the spun yarn Y therebetween.
  • an amount of light received by the light-receiver 72 can be calculated by subtracting light shielded by the spun yarn Y from the light emitted from the light source 71 to illuminate the spun yarn Y.
  • the yarn-defect detecting device 7 is capable of measuring the amount of received light according to yarn thickness and therefore can detect a defect in the spun yarn Y.
  • Defects that can be detected by the yarn-defect detecting device 7 include anomalies, for example, that a portion of the spun yarn Y is too thick or too thin, and a foreign matter, such as a polypropylene foreign matter, interposed into the spun yarn Y.
  • the yarn-defect detecting device 7 can adopt an electrical capacitance sensor in lieu of the optical sensor described above.
  • the tension stabilizer 8 maintains proper tension on the spun yarn Y and stabilizes the tension.
  • the tension stabilizer 8 includes a roller 81, a power output section 82, and an unwinding member 83. Note that arrows shown in FIG. 6 indicate the feed direction of the spun yarn Y.
  • the roller 81 is a substantially cylindrical rotary member used in pulling out the spun yarn Y from the air spinning device 6 and winding the spun yarn Y around itself.
  • the roller 81 is arranged on a rotary shaft 82a of the power output section 82 and rotated by the power output section 82.
  • the spun yarn Y pulled out from the air spinning device 6 is wound around an outer peripheral surface of the roller 81.
  • the power output section 82 As the power output section 82, an electric motor that is driven on electric power supplied thereto is used.
  • the power output section 82 rotates the roller 81 while maintaining the rotation speed of the roller 81 at a predetermined value. This makes it possible to wind the spun yarn Y around the roller 81 at a constant winding speed.
  • the unwinding member 83 is a threading member that rotates in combination with or separately from the roller 81 to thereby assist unwinding of the spun yarn Y.
  • the unwinding member 83 is provided on its one end to a rotary shaft 84 of the roller 81.
  • a portion on the other end of the unwinding member 83 is curved toward the outer peripheral surface of the roller 81.
  • a permanent magnet that exerts a resisting force against rotation of the unwinding member 83 is provided at a basal portion of the rotary shaft 84, to which the unwinding member 83 is attached.
  • the unwinding member 83 configured in this way rotates in combination with the roller 81 when a tension placed on the spun yarn Y is relatively weak and overcome by the resisting force. In contrast, the unwinding member 83 rotates separately from the roller 81 when the tension placed on the spun yarn Y is relatively strong to overcome the resisting force.
  • the tension stabilizer 8 can thus cause the unwinding member 83 to rotate in combination with or separately from the roller 81 depending on the tension placed on the spun yarn Y, thereby adjusting an unwinding speed of the spun yarn Y.
  • the tension stabilizer 8 maintains a proper tension on the spun yarn Y and stabilizes the tension in this way.
  • the tension stabilizer 8 can wind the spun yarn Y around the outer peripheral surface of the roller 81 to store the spun yarn Y.
  • the tension stabilizer 8 can therefore take up a slack in the spun yarn Y.
  • the winding device 9 winds the spun yarn Y to thereby form a substantially cylindrical (cheese-shaped) package P.
  • the winding device 9 includes a driving roller 91 and a cradle (not shown).
  • the cradle rotatably supports a bobbin 92.
  • the driving roller 91 is a rotary member that rotates to cause the bobbin 92 and the package P to be rotated by rotation of the driving roller 91.
  • the driving roller 91 adjusts its rotation speed according to change in the outer diameter of the package P, thereby maintaining the circumferential velocity of the package P constant. This makes it possible to wind the spun yarn Y on the bobbin 92 at a constant winding speed.
  • the bobbin 92 is a substantially cylindrical rotary member around which the spun yarn Y is wound.
  • the bobbin 92 is rotated by the rotation of the driving roller 91 that rotates in contact with the outer peripheral surface of any one of the bobbin 92 and the package P.
  • a traversing device (not shown) causes the spun yarn Y to be traversed to prevent unbalanced winding of the spun yarn Y on the package P.
  • the spun yarn Y introduced to the bobbin 92 is wound, without being unbalanced, on the outer peripheral surface of the bobbin 92.
  • the winding device 9 can form the substantially cylindrical (cheese-shaped) package P in this way.
  • the package P to be formed by the winding device 9 is not limited to the substantially cylindrical (cheese-shaped) package P shown in FIG. 1 .
  • the winding device 9 can also form the package P having a substantially conical shape.
  • the air spinning device 6 produces the spun yarn Y by twisting the sliver F by utilizing the swirling airflow. More specifically, in the space SC1 of the spinning chamber SC, the trailing-end portions of the fibers that form the sliver F are turned over (see the long dashed double-short dashed line in FIGS. 3 and 4 ) by the swirling airflow. In the space S2 of the spinning chamber SC, the trailing-end portions of the fibers that form the sliver F are swung (see the long dashed double-short dashed line in FIGS. 3 and 4 ) by the swirling airflow.
  • fibers to be spun are synthetic fibers having a relatively long average fiber length of 32 millimeters (mm) to 51 mm.
  • Synthetic fibers generally possess high stiffness as their inherent material property. Accordingly, if a distance D between the spindle 62 and the fiber guide 61 is shorter than a predetermined value (e.g., 2.6 mm), trailing-end portions of the synthetic fibers are hard to be turned over. As a result, the spun yarn Y that is loosely twisted is produced. More specifically, if the distance D between the spindle 62 and the fiber guide 61 is relatively short (e.g., shorter than 2.6 mm), only a small number of the trailing-end portions of the synthetic fibers are moved by and along the swirling airflow.
  • a predetermined value e.g., 2.6 mm
  • the distance D between the spindle 62 and the fiber guide 61 is longer than the predetermined value (e.g., 2.6 mm), a sufficient number of the trailing-end portions of the synthetic fibers are turned over. As a result, the spun yarn Y that is firmly twisted is produced. More specifically, if the distance D between the spindle 62 and the fiber guide 61 is relatively long (e.g., 2.6 mm or longer), the trailing-end portions of the synthetic fibers are moved by and along the swirling airflow easily, and hence the sufficient number of the trailing-end portions is turned over.
  • the predetermined value e.g., 2.6 mm
  • the synthetic fibers in a state where the sufficient number of the trailing-end portions of the synthetic fibers are wound around central fibers in the space SC2 are introduced into the fiber passageway 62s.
  • a firmly-twisted spun yarn (firm yarn) Y is produced.
  • both ends of the synthetic fibers are swung in the spinning chamber SC without being restricted by either of the fiber guide 61 and the spindle 62. Accordingly, the synthetic fibers are discharged to the outside of the air spinning device 6 more frequently. As a result, fiber loss increases, which is disadvantageous.
  • the distance D increases, the volumetric capacity of the spinning chamber SC increases, and hence the amount of air that needs to be used in producing the swirling airflow also increases. Accordingly, the need for increasing the size of the air pressure conveying device arises. This requires upsizing of the spinning unit 1, which is also disadvantageous.
  • fibers to be spun are natural fibers having a relatively short average fiber length of, for example, shorter than 32 mm. Natural fibers generally possess low stiffness as their inherent material property. However, if the distance D between the spindle 62 and the fiber guide 61 is shorter than a predetermined value (e.g., 1.6 mm), trailing-end portions of the natural fibers cannot be turned over easily. As a result, a spun yarn Y that is loosely twisted is produced. More specifically, if the distance D between the spindle 62 and the fiber guide 61 is relatively short (e.g., shorter than 1.6 mm), only a small number of the trailing-end portions of the natural fibers are moved by and along the swirling airflow.
  • a predetermined value e.g., 1.6 mm
  • the distance D between the spindle 62 and the fiber guide 61 is longer than the predetermined value (e.g., 1.6 mm), a sufficient number of the trailing-end portions of the natural fibers are turned over.

  • the natural fibers in a state where the sufficient number of the trailing-end portions of the natural fibers are wound around central fibers in the space SC2 are introduced into the fiber passageway 62s.
  • a firmly-twisted spun yarn (firm yarn) Y is produced.
  • both ends of the natural fibers are swung in the spinning chamber SC without being restricted by either of the fiber guide 61 and the spindle 62. Accordingly, the natural fibers are discharged to the outside of the air spinning device 6 more frequently. As a result, fiber loss increases, which is disadvantageous.
  • the distance D increases, the volumetric capacity of the spinning chamber SC increases, and hence the amount of air that needs to be used in producing the swirling airflow also increases. Accordingly, the need for increasing the size of the air pressure conveying device arises. This requires upsizing of the spinning unit 1, which is also disadvantageous.
  • the description about the distance D and the firmness of the spun yarn Y holds true not only for a case where the entire sliver F is formed with natural fibers, but also for a case where the sliver F of synthetic fibers contains a relatively high proportion of natural fibers and a case where the sliver F is formed with synthetic fibers of which average fiber length is less than 32 mm.
  • the spun yarn Y made by the air spinning device 6 is likely to be influenced by fiber characteristics because the air spinning device 6 causes fibers to swing by utilizing the swirling airflow.
  • the air spinning device 6 is disadvantageous in that twisting firmness of the produced spun yarn Y varies according to fiber characteristics, such as an average fiber length.

In a case where a yarn structure of the spun yarn Y is highly stable, even when the spun yarn Y is rolled a plurality of times, the spun yarn Y will not be easily untwisted. In this case, a numerical value indicating the rolling endurance RP is relatively large.
  • the distance D between the spindle 62 and the fiber guide 61 of the air spinning device 6 is set to a value from 2.6 mm to 4.1 mm.
  • the range of the distance D from 2.6 mm to 4.1 mm is determined based on a result of a test carried out by using twisting firmness of the spun yarn Y according to fiber characteristics as a parameter.

  • the spinning method can alternatively be implemented in a structure in which a mounting position of the spindle 62 can be changed to achieve adjustment of the distance D.
  • the spinning method can be implemented in a configuration in which a plurality of the air spinning devices 6 that differ from one another in the distance D are prepared. With this configuration, the air spinning device 6 is switched to another one of the air spinning devices 6 that is suitable for a type of the sliver F.
  • the spinning unit 1 includes an input screen 10 for receiving input of information relating to a type of the sliver F.
  • the input screen 10 also functions as a display unit that displays information about the air spinning device 6 suitable for the type of the sliver F.

  • one of the air spinning devices 6 in which the distance D between the spindle 62 and the fiber guide 61 is set to be longer than or equal to 3.1 mm and shorter than or equal to 3.6 mm is displayed.
  • one of the air spinning devices 6 in which the distance D between the spindle 62 and the fiber guide 61 is set to be longer than or equal to 1.8 mm and shorter than or equal to 2.3 mm is displayed.
  • This configuration makes it possible to select one of the air spinning devices 6 suitable for fiber characteristics without fail. Accordingly, a troublesome job that can otherwise be involved in changing the sliver F to be spun to the sliver F having different fiber characteristics is made easier.
  • the spun yarn Y spun by the air spinning device 6 is drawn out and temporarily stored by the tension stabilizer 8.
  • the configuration of the spinning unit 1 is not limited to such a configuration.
  • a configuration is allowable in which a delivery roller and a nip roller are arranged downstream of the air spinning device 6, and the delivery roller and the nip roller draw out the spun yarn Y from the air spinning device 6.
  • a configuration is allowable in which the tension stabilizer 8 is arranged downstream relative to the delivery roller and the nip roller, and the spun yarn Y drawn out from the air spinning device 6 by the delivery roller and the nip roller is temporarily stored by the tension stabilizer 8.
  • a configuration in which the tension stabilizer 8 is omitted and the winding device 9 directly winds the spun yarn Y can be employed.
  • the present invention yields the following effects.
  • an air spinning device including a spindle and a fiber guide that are separated by a distance longer than or equal to 2.6 mm and shorter than or equal to 4.1 mm, quality of the spun yarn can be stabilized.
  • a spun yarn can be produced from a plurality of types of fiber bundles of which average fiber lengths are longer than or equal to 32 mm and shorter than or equal to 51 mm.
