Description

Fancy yarn manufacturing device

Technical Field

The following disclosure relates to an apparatus for manufacturing an effect yarn composed of a main yarn and decorative fibers intermittently cut and interlaced with the main yarn.

Background

For the purpose of imparting a decorative effect to a woven fabric or a knitted fabric, a periodic or aperiodic change such as a loop or a slub may be imparted to the yarn in advance. The yarn to which this variation is applied is generally referred to as fancy yarn. Many fancy yarns have been proposed so far.

The method of manufacturing the effect yarn is not fixed, and may be changed at the stage of the spinning step, or may be changed by processing after being spun into a yarn. In the case of processing, one yarn may be processed, and another yarn may be interlaced with the 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, the terms upstream and downstream are defined and used with respect to the direction of travel of the threads.

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 decorative fibers 5C intermittently cut and interlaced 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 apparatus generally comprises: a main yarn supply bobbin holder 11 for feeding out the main yarn 1; a decoration thread cylinder frame 15 for sending out the decoration thread 5; a twisting device 23; and a winder 31. The main yarn 1 travels from the main yarn supply creel 11 to the twisting device 23 through the confluence region 17. In order to guide the main thread 1 in this manner, thread guides such as rings and rollers can be appropriately arranged.

The device is also provided with a jet nozzle 19 which directs an air flow a 1. The decoration thread 5 passes through the jet nozzle 19, is intermittently cut by the cutter 21 to become decoration fibers 5c, and is supplied to the merging region 17 by the air flow a1 to be merged with the main thread 1.

The device may also comprise a secondary supply creel 13 that feeds the secondary thread 3. The sub-threads 3 merge with the main thread 1 downstream of the merging region 17.

The twisting device 23 is disposed downstream of the confluence region 17, and is disposed downstream of the part when the sub-threads 3 are joined. The twisting device 23 is, for example, a false twisting device, and false twisting is applied to the entire yarn 1, 3 and the decorative fiber 5c to form the effect yarn 10, and the effect yarn 10 is collected in the winder 31. Alternatively, the twist may be a solid twist as described later.

In the example shown in fig. 1, the main thread, the sub-thread, and the decoration thread are fed from three yarn supply creels, respectively, but two or more main threads or two or more sub-threads may be fed by adding more yarn supply creels. In this case, a combination of a decorative yarn barrel holder, an injection nozzle, a cutter, and a merging region may be added. The two or more decoration wires may be provided in different colors and different thicknesses, respectively.

Referring to fig. 3 in conjunction with fig. 1, the spray nozzle 19 is, for example, an elongated hollow tube, and has one end connected to a blower such as a blower, for example, and the other end opened toward the joining region 17. In principle, the air flow a1 generated by the blowing device always flows in the injection lance 19 from one end to the other end during operation of the device. The decoration wire 5 is drawn out from the decoration wire barrel frame 15, introduced into the injection nozzle 19 from the vicinity of the one end, and injected from the other end while being entrained by the air flow a 1.

The cutter 21 is disposed, for example, between the jet nozzle 19 and the confluence region 17. The cutter 21 is for example a sickle with a knife edge. The decoration wire 5 ejected from the ejection nozzle 19 is always swung and 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 decoration wire 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 a rotation, thereby generating an air flow a 2. The air flow a1 ejected from the ejection nozzle 19 is mixed with the air flow a2, and an air flow A3 having a complicated operation including stagnation and rotation is generated around the main yarn 1. The cut decorative fibers 5c may join along the main yarn 1 by riding the air flow a3, and are carried to the twisting device 23 together with it. At this time, the form of the decoration fiber 5c with respect to the main thread 1 is, for example, as shown in fig. 6A, that is, only along the main thread 1 or slightly twisted.

Referring to fig. 3, the device may also include one or more walls 33 in order to rectify the air flow in the merging region 17. At least one of the walls 33 can be arranged, for example, in an orientation and position that rectifies the air flow a1 towards the main wire 1. The other wall 33 may be disposed to rectify the air flow in the direction along the travel direction of the main wire 1, for example. They help to wind the decoration fibers 5c around the main thread 1.

The decoration wire 5 can be intermittently fed to promote cutting, and for this purpose, for example, the decoration wire bobbin 15 can be provided with a servo motor. Alternatively, the roller for guiding the decoration wire 5 may be provided with a servo motor. When the servo motor is operated intermittently, the decoration wire 5 can be supplied intermittently. When the leading end of the decoration wire 5 comes into contact with the main wire 1 and the servo motor is stopped, the tension is applied to the decoration wire 5 at that moment, and the cutter 21 is promoted to cut. Alternatively, the decoration wire 5 may be cut without contacting the cutter in some cases. Alternatively, the decoration thread 5 may be cut before the leading end comes into contact with the main thread 1, and the cut decoration fiber 5c may be caused to fly toward the main thread 1 by the air flow a1 and be entangled therewith.

Alternatively, instead of intermittently operating the servo motor, or in addition to this, a 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 clip 19A is operated by a solenoid or the like to intermittently hold the decoration wire 5, the decoration wire 5 is momentarily stopped and cut by the cutter 21. The jig 19A may be outside the injection nozzle 19, unlike fig. 4.

As shown in fig. 3, the cutter 21 may be provided outside the spray nozzle 19, but may be provided inside the spray nozzle 19 as shown in fig. 4. The apparatus may further include a second clamp 19B at a position downstream of the cutter 21. According to this configuration, the previously cut decorative fibers 5c are prepared, and the second clamp 19B releases the prepared decorative fibers to sequentially supply the decorative fibers 5c to the confluence region 17.

Alternatively, the decoration wires 5 may be cut in advance outside the injection nozzle 19, and the cut decoration fibers 5c may be sequentially supplied to the injection nozzle 19.

Referring back to fig. 1, the main yarn 1 with the ornamental fibers 5c advances toward the twisting device 23, but the device is configured to merge the sub-yarns 3 downstream of the merging region 17 and upstream of the twisting device 23. By twisting the sub thread 3 together with the main thread 1 and the decoration fiber 5c, the decoration fiber 5c is twisted with the main thread 1. Alternatively, by applying a thread having properties different from those of the main thread 1 to the sub-threads 3, design properties or functionality can be imparted to the effect yarn 10.

For the joining and twisting, for example, an air nozzle 23 such as a rotary nozzle that imparts a false twist to the yarn by rotating an air flow can be used. By the rotary nozzle, the main yarn 1 and the sub yarn 3 are rotated to urge the decorative fibers 5c into the main yarn 1 and the sub yarn 3. This is advantageous in that the decorative fibers 5c are prevented from falling off. Instead of a rotary nozzle, for example, a hollow shaft may be used. Alternatively or in addition thereto, heating or the like may be applied.

The decoration fiber 5c passes through the air nozzle 23 together with the main thread 1 and the sub thread 3, and thereby may be wound in a winding manner. The air nozzle 23 is used exclusively for preventing the falling of the decoration fibers 5c, and the wires 1, 3 do not necessarily need to be bundled. The form of the yarns 1 and 3 and the decorative fibers 5c after passing through the air nozzle 23 is, for example, as shown in fig. 6B.

Referring back to fig. 1, the yarns 1 and 3 and the decorative fibers 5c merged with each other are guided to the interlacing device 25. The interweaving device 25 may comprise water imparting guides 27. The water supply guide 27 is a yarn guide provided with a nozzle capable of jetting a small amount of water to the yarn. Alternatively, instead of using the water application guide 27, the weaving nozzle 29 described later may be provided with a water nozzle. By imparting a small amount of water to the yarn, the interlacing of the yarns 1, 3 and the decoration fibers 5c can be further enhanced.

The interleaving device 25 includes air nozzles such as interleaving nozzles 29. Referring to fig. 5, a known interleaving nozzle can be applied to the interleaving nozzle 29. The interlacing nozzle 29 includes 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 configured to be tapered at least on the guide hole 41 side, thereby ejecting a relatively high-speed air flow a4 into the guide hole 41. The air flow a4 ejected into the guide hole 41 generates a relatively high-speed turbulent flow at its outlet, which imparts interlacing to the yarn passing through the guide hole 41.

The water-applied yarns 1 and 3 and the decorative fibers 5C are passed through the interlacing nozzle 29, whereby the yarns 1 and 3 are gathered together, and are interlaced together with the decorative fibers 5C to be strongly twisted with each other, whereby the effect yarn 10 as shown in fig. 6C is obtained.

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

In the above description, an example of applying the false twist to the yarn was described, but the true twist may be applied instead of the false twist. Fig. 2 is an example based on a solid twist, the twisting device 23b being a solid twist device, for example a combination of a twister and a shaft. In this case, the spindle also functions as a winder. By the solid twist, of course, the decoration fibers 5c are also firmly wound in the wires 1, 3, and the wires 1, 3 are more firmly bundled. Since the decoration fibers 5c can be firmly wound around the main yarn 1 at the time of the real twisting, the interlacing device 25 can be omitted.

In this example, the thread guide 23a may be provided downstream of the confluence region 17 and upstream of the twisting device 23 b. The yarn guide 23a has only a function of exclusively guiding the sub yarn 3 so as to merge with the main yarn 1 and the decorative yarn 5, or may be accompanied by a structure of turning and processing the yarn.

Referring back to fig. 6C, the effect yarn 10 of the present embodiment has a relatively long fluffy structure obtained from decorative fibers cut short. Each structure is in a pile shape, but is not easily detached as a pile because it is firmly wound around the main yarn and the sub yarn.

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

In the conventional method for producing an effect yarn, in many cases, a structure of a loop or a slub is formed by processing a continuous filament yarn, and therefore, the tip of the fiber is not spread to the outside of the effect yarn, and a structure such as a long pile cannot be formed as in the present embodiment. In addition, in the conventional manufacturing method, the control of the interval between the structures and the size of each structure cannot be performed as freely. According to the present embodiment, these can be easily achieved. Furthermore, according to the present embodiment, different colors can be given to each structure.

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