Description

Fancy yarn manufacturing device

Technical Field

The following disclosure relates to an apparatus for manufacturing fancy yarn composed of a main yarn and a decorative fiber intermittently cut and interwoven with the main yarn.

Background

For the purpose of providing a decorative effect or the like to a woven fabric or knit fabric, a periodic or aperiodic change such as a loop yarn or a slub yarn may be imparted to the yarn in advance. Yarns to which this variation is applied are commonly referred to as fancy yarns. To date, many fancy yarns have been proposed.

The method for producing the fancy yarn is not fixed, and may be changed at the stage of the spinning process, or may be changed by processing the spun yarn after the spun yarn is formed into a yarn. In the case of processing, there are cases where one yarn is processed and other yarns are interwoven with one yarn.

Detailed Description

Several exemplary embodiments are described below with reference to the accompanying drawings. In the following description and claims, unless otherwise indicated, terms upstream and downstream are defined and used with respect to the direction of travel of the wire.

As shown in fig. 6A to 6C, the apparatus of the present embodiment can be applied to the use of manufacturing a fancy yarn 10 that includes at least a main yarn 1 and a decorative fiber 5C intermittently cut and interwoven therewith, and can further include a sub-yarn 3. The effect yarn 10 is used, for example, for textiles or knits and gives them a decorative effect.

Referring mainly to fig. 1, the device generally comprises: a main yarn feeding bobbin 11 for feeding out the main yarn 1; a decorative thread cylinder 15 for feeding the decorative thread 5; a twisting device 23; a winder 31. The main yarn 1 passes from the main supply bobbin 11 through the joining region 17 to the twisting device 23. In order to guide the main yarn 1 in this way, yarn guides such as rings and rollers can be appropriately arranged.

The device is further provided with a jet nozzle 19 for guiding the air flow A1. The decorative yarn 5 passes through the jet nozzle 19, is intermittently cut by the cutter 21 to become decorative fibers 5c, and is supplied to the joining region 17 by the air flow A1 to join the main yarn 1.

The device may also comprise a secondary feed creel 13 for feeding out the secondary yarn 3. The secondary yarn 3 merges with the primary yarn 1 downstream of the merging region 17.

The twisting device 23 is disposed downstream of the joining region 17, and is disposed downstream of this region when the sub-wires 3 join. The twisting device 23 is, for example, a false twisting device, and performs false twisting on the entire filaments 1, 3 and the decorative fiber 5c to obtain the fancy yarn 10, and the fancy yarn 10 is taken back to the winder 31. Or may be solid twist as will be described later.

In the example shown in fig. 1, the main yarn, the sub yarn, and the decorative yarn are fed from three yarn feeding bobbins, respectively, but two or more main yarns or two or more sub yarns may be fed by adding yarn feeding bobbins. In this case, a combination of a decorative thread tube holder, a jet nozzle, a cutter, and a joining region may be added. The two or more decorative threads can be respectively set to different colors and different thicknesses.

Referring to fig. 3 in conjunction with fig. 1, the injection nozzle 19 is, for example, an elongated hollow tube, and is connected at one end thereof to an air blowing device such as a blower, for example, and the other end thereof opens toward the merging region 17. In principle, the air flow A1 always generated by the blower device flows in the jet nozzle 19 from one end to the other during operation of the device. The decorative thread 5 is led out from the decorative thread cylinder 15, guided into the jet nozzle 19 from the vicinity of the one end, and ejected from the other end by the air flow A1.

The cutter 21 is disposed, for example, between the jet pipe 19 and the joining region 17. The cutter 21 is for example a sickle with a knife edge. The decorative thread 5 ejected from the jet nozzle 19 always swings and is cut by contact with the cutter 21. Alternatively, scissors or clippers may be applied to the cutter 21 instead of the sickle, and the cutter 21 may be provided with a driving device such as a motor mechanism or a solenoid mechanism for driving them. Alternatively, the decorative thread 5 may be cut by a thermal mechanism or a laser.

The main yarn 1 always travels, vibrates, and performs a complicated operation such as turning, thereby generating an air flow A2. The air flow A1 ejected from the ejection nozzle 19 is mixed with the air flow A2, and an air flow A3 including a complex operation of stagnation and rotation is generated around the main yarn 1. The cut decorative fibers 5c may merge along the main yarn 1 by riding the air flow A3, and be carried to the twisting device 23 together with it. At this time, the form of the decorative fiber 5c with respect to the main yarn 1 is as shown in fig. 6A, for example, that is, only along the main yarn 1 or slightly wound.

Referring to fig. 3, the device may be provided with one or more walls 33 for rectifying the air flow in the junction region 17. At least one of the walls 33 can be arranged, for example, in an orientation and in a position to rectify the air flow A1 towards the main wire 1. The other of the walls 33 may be disposed so as to rectify the air flow in the traveling direction of the main yarn 1, for example. They help to wind the decorative fibers 5c around the main thread 1.

For this purpose, for example, the yarn winding frame 15 may be provided with a servo motor. Alternatively, the roller guiding the decorative thread 5 may be provided with a servomotor. When the servo motor is intermittently operated, the decorative thread 5 can be intermittently supplied. If the tip of the decorative wire 5 contacts the main wire 1 and the servo motor is stopped, tension is applied to the decorative wire 5 at that instant, and thus the cutter 21 is promoted to cut. Alternatively, the decorative thread 5 can be cut without touching the cutter, as the case may be. Alternatively, the decorative thread 5 may be cut before the tip end contacts the main thread 1, and the cut decorative fiber 5c may fly toward the main thread 1 by the air flow A1 and be wound around the same.

Alternatively, instead of intermittently operating the servo motor, or in addition thereto, the jig 19A that is intermittently operated as shown in fig. 4 may be used. For the operation of the clamp 19A, a driving device such as a solenoid may be used. When the clamp 19A is operated by a solenoid or the like to intermittently clamp the decorative thread 5, the decorative thread 5 is stopped instantaneously and cut by the cutter 21. The clamp 19A may be outside the injection nozzle 19 unlike in fig. 4.

The cutter 21 may be located outside the jet nozzle 19 as shown in fig. 3, but may be located inside the jet nozzle 19 as shown in fig. 4. The device may further include a second clamp 19B downstream of the cutter 21. According to this configuration, the decorative fibers 5c cut in advance are prepared, and the second jig 19B releases the decorative fibers to sequentially supply the decorative fibers 5c to the joining region 17.

Alternatively, the decorative thread 5 may be cut in advance outside the jet nozzle 19, and the cut decorative fibers 5c may be sequentially supplied to the jet nozzle 19.

Referring back to fig. 1, the main yarn 1 accompanied by the decorative fiber 5c travels toward the twisting device 23, but the device is configured such that the sub-yarn 3 merges downstream of the merging region 17 and upstream of the twisting device 23. The decorative fiber 5c is wound around the main yarn 1 by twisting the sub yarn 3 together with the main yarn 1 and the decorative fiber 5 c. Alternatively, by applying a yarn having different properties from the main yarn 1 to the sub-yarn 3, design or functionality can be imparted to the fancy yarn 10.

For this joining and twisting, for example, an air nozzle 23 such as a rotary nozzle for imparting false twist to the yarn by rotating air back can be used. By using the rotary nozzle, the main silk thread 1 and the auxiliary silk thread 3 rotate, so that the decorative fiber 5c is driven to enter the main silk thread 1 and the auxiliary silk thread 3. This is advantageous in that the decorative fibers 5c are prevented from falling off. Instead of a rotary nozzle, a hollow shaft, for example, may also be used. Alternatively, heating or the like may be applied in place of or in addition to this.

The decorative fiber 5c passes through the air nozzle 23 together with the main yarn 1 and the sub yarn 3, thereby being possibly wound in a winding manner. The air nozzle 23 is dedicated to preventing the shedding of the decorative fibers 5c, and it is not necessary to bundle the threads 1, 3. The form of the filaments 1, 3 and the decorative fibers 5c passing through the air nozzle 23 is as shown in fig. 6B, for example.

Returning to and referring to fig. 1, the mutually converging filaments 1, 3 and the decorative fibers 5c are led to an interweaving device 25. The interweaving means 25 may comprise a water imparting guide 27. The water-imparting guide 27 is a yarn guide provided with a nozzle capable of spraying a small amount of water onto the yarn. Alternatively, instead of using the water applying guide 27, the interlacing nozzle 29 described later may be provided with a water nozzle. The interlacing of the threads 1, 3 and the decorative fibers 5c can be further enhanced by imparting a small amount of water to the threads.

The interlacing device 25 includes an air nozzle such as the interlacing nozzle 29. Referring to fig. 5, a known interleaving nozzle can be applied to the interleaving nozzle 29. The interlacing jet 29 is provided with a guide hole 41 through which the yarn passes and an air passage 43 communicating with the guide hole 41. The air duct 43 is connected to an external blower like a blower, and is tapered at least on the guide hole 41 side, so that a relatively high-speed air flow A4 is discharged into the guide hole 41. The air flow A4 ejected into the guide hole 41 generates turbulence at a relatively high speed at its outlet, which imparts interlacing to the yarn passing through the guide hole 41.

The yarn 1, 3 to which water is applied and the decorative fiber 5C pass through the interlacing jet 29, whereby the yarn 1, 3 are bundled together, and the yarn is interlaced with the decorative fiber 5C to be firmly wound around each other, thereby obtaining the fancy yarn 10 shown in fig. 6C.

In the above description, an example using an interlacing jet is described, but instead of this, an interlacing jet may be used, or a yarn processing device such as a hollow shaft or a combination of a friction twisting device and a heating device may be used. Alternatively, instead of the processing unit using these wires, heating and bonding may be used. Examples of the heating means include a heater, a laser, and an ultrasonic wave generating device.

In the above description, the case where the false twist is applied to the yarn has been described, but the false twist may be applied instead of the false twist. Fig. 2 is an example based on a real twisting, the twisting device 23b being a real twisting device, for example a combination of a twisting machine and a shaft. In this case, the main shaft also functions as a winder. By solid twisting, of course, the decorative fiber 5c is also firmly wound in the filaments 1, 3, the filaments 1, 3 being more firmly bundled. Since the decorative fiber 5c can be firmly wound around the main yarn 1 at the time of actual twisting, the interlacing device 25 may be omitted.

In this example, the yarn guide 23a may be provided downstream of the joining region 17 and upstream of the twisting device 23 b. The yarn guide 23a may have only a function of guiding the sub yarn 3 exclusively so as to merge with the main yarn 1 and the decorative yarn 5, or may be accompanied by a structure in which a rotation and a working are applied to the yarn.

Referring back to fig. 6C, the effect yarn 10 of the present embodiment has a relatively long fluff-like structure obtained from a decorative fiber cut relatively short. Each structure is fluff-like, but is not easily detached as fluff because it is firmly entangled with the main yarn and the sub yarn.

The size of the structure can be freely changed according to the length of the cut decorative thread, and the interval between adjacent structures can be freely changed according to the interval of the cut decorative thread. Of course, the size and spacing may also be varied for each structure. Further, as described above, two or more decorative threads can be used, and thus, for example, different colors can be used for each structure.

In the conventional method for producing a fancy yarn, in many cases, a loop or slub yarn is formed by processing a continuous filament yarn, and therefore the tip of the fiber does not spread out of the fancy yarn, and a structure such as a long fluff is not formed as in the present embodiment. In addition, in the conventional manufacturing method, the interval between structures and the size of each structure cannot be controlled so freely. According to the present embodiment, these can be easily realized. Further, according to the present embodiment, a different color can be given to each structure.

Although the embodiments have been described, modifications and variations of the embodiments can be made based on the above disclosure.
