Description

Fabrication yarn manufacturing device

The present invention relates to an apparatus for manufacturing a decorative yarn composed of main yarns and decorative fibers intermittently cut and entwined with the main yarns.

For the purpose of imparting decorative effects to woven or knitted fabrics, there are cases in which periodic or non-periodic changes such as loops or slubs are previously applied to yarns. Yarns endowed with these variations are often referred to as design yarns. So far, numerous design designs have been proposed.

The manufacturing method of the design yarn is not constant, and there are cases where changes are applied at the stage of the spinning process, and there are cases where changes are imparted by processing the yarn after it is made into yarn through spinning. Even in the case of processing, there are cases in which one yarn is processed, and in other cases, one yarn is entwined with other yarns.

Several exemplary embodiments are described below with reference to the accompanying drawings. In the following description and claims, unless otherwise specified, the terms upstream and downstream are defined and used in relation to the direction in which threads travel.

As shown in Figs. 6A to 6C, the device includes at least a main yarn 1 and a decorative fiber 5c intermittently cut and intertwined with them, and a secondary yarn. (Secondary yarn) (3) can be used suitably for the purpose of manufacturing the decorative yarn (10). These decorative yarns 10 are used, for example, in fabrics or knitted fabrics to impart a decorative effect to them.

Referring primarily to FIG. 1, this device generally includes a main feeding yarn creel 11 for sending out the main yarn 1, a decorative yarn creel 15 for sending out the decorative yarn 5, and a twisting device 23 , a winder 31 is provided. The injection tank 1 travels from the main yarn creel 11 to the twisting device 23 through the confluence area 17. A thread guide such as a ring or a roller may be suitably arranged to guide the scanning tub 1 in this way.

The device also has a jet nozzle 19 guiding the airflow A1. The decorative threads 5 pass through these jet nozzles 19, are also intermittently cut by the cutter 21 to become decorative fibers 5c, and are supplied to the confluence area 17 by the airflow A1 to be scanned. Join with Article (1).

The device may further include a subsidiary yarn creel 13 for sending out the subsidiary yarn 3. The secondary thread 3 joins the scanning thread 1 downstream from the confluence area 17 .

The twisting device 23 is disposed downstream of the confluence area 17, further downstream from that place when the braiding yarn 3 joins. The false twisting device 23 is, for example, a false twisting device, and false twist is applied to the entirety of the yarns 1 and 3 and the decorative fiber 5c to become the decorative yarn 10, and the decorative yarn 10 is a winder are drawn into (31). Alternatively, thread twist may be used as will be described later.

In the example shown in Fig. 1, main yarns, auxiliary yarns, and decorative yarns are sent out from three yarn feeding creels, respectively, but two or more main yarns or two or more auxiliary yarns may be sent out by increasing the number of feeding yarn creels. Also, two or more decorative yarns may be used, and in that case, a combination of a decorative yarn creel, a jet nozzle, a cutter, and a joining area is added. Two or more decorative threads can be made in different colors and different thicknesses.

Referring to FIG. 3 in combination with FIG. 1 , the jet nozzle 19 is elongated, for example, connected at one end to a blowing device such as a blower, and at the other end a confluence area 17 is open towards When the device is operating, in principle, the air flow A1 by the blower always flows through the inside of the jet nozzle 19 from one end to the other end. The decorative yarns 5 are drawn out from the decorative yarn creel 15, introduced into the jet nozzle 19 from the vicinity of the one end, and discharged from the other end along the airflow A1.

The cutter 21 is arranged between the jet nozzle 19 and the confluence area 17, for example. The cutter 21 is, for example, a sickle with a blade. The decorative yarn 5 discharged from the jet nozzle 19 is constantly swaying, and is cut when it touches the cutter 21 . Alternatively, instead of a scythe, scissors or a hair clipper can be applied to the cutter 21, and the cutter 21 may be provided with a drive device such as a motor mechanism or a solenoid mechanism to drive them. Alternatively, the decorative yarn 5 may be cut using a thermal means or a laser.

The scanning tub 1 always travels, oscillates, and performs complicated movements such as turning, and an airflow A2 is generated along with this. The air stream A1 discharged from the jet nozzle 19 is mixed with the air stream A2 to generate an air stream A3 with complex motions around the injection tank 1 including retention and swirling. The cut decorative fibers 5c, possibly by riding on this airflow A3, follow the casting tub 1, join them, and are transferred to the twisting device 23 together with it. At this time, the manner of the decorative fiber 5c relative to the thread 1 will be such that it simply follows the thread 1 or is lightly entangled, as shown in Fig. 6A, for example.

Referring to FIG. 3 , the device may have one or more walls 33 to rectify the airflow at the confluence area 17 . At least one of the walls 33 can be arranged in a direction and position to rectify the air flow A1 towards the injection vessel 1, for example. Another one of the walls 33 can also be arranged to rectify the airflow, for example in a direction following the travel of the injection tank 1 . These are helpful in entangling the decorative fibers 5c in the thread 1.

To facilitate cutting, the decorative yarn 5 may be fed intermittently, for which purpose the decorative yarn creel 15, for example, may be equipped with a servomotor. Alternatively, the rollers guiding the decorative threads 5 may be provided with a servomotor. When the servo motor is operated intermittently, the decorative threads 5 are supplied intermittently. When the tip of the decorative thread 5 touches the scanning thread 1 or the servomotor is stopped, tension is applied to the decorative thread 5 at that moment, so cutting by the cutter 21 is promoted. Alternatively, in some cases, the decorative threads 5 can be cut without touching the cutter. Alternatively, the decorative thread 5 is cut before the tip touches the thread 1, and the cut decorative fiber 5c is made to fly toward the thread 1 by the airflow A1, thereby may be entangled.

Alternatively, instead of or in addition to operating the servomotor intermittently, as shown in Fig. 4, the intermittently operating clamp 19A can be used. A driving device such as a solenoid can be used to operate the clamp 19A. When the clamp 19A is operated by a solenoid or the like to intermittently clamp the decorative yarn 5, the decorative yarn 5 is instantly stopped and cut by the cutter 21. Unlike FIG. 4 , the clamp 19A may be outside the jet nozzle 19 .

In addition, the cutter 21 may be outside the jet nozzle 19 as shown in FIG. 3 , but may be arranged inside the jet nozzle 19 as shown in FIG. 4 . Further downstream of the cutter 21, the device may include a second clamp 19B. According to this configuration, pre-cut decorative fibers 5c are prepared, and the second clamp 19B releases them, thereby supplying the decorative fibers 5c to the confluence area 17 one after another.

Alternatively, the decorative yarn 5 may be previously cut outside the jet nozzle 19, and then the cut decorative fibers 5c may be supplied to the jet nozzle 19 in order.

Referring again to FIG. 1 , the yarn thread 1 carrying the decorative fibers 5c runs toward the twisting device 23, downstream of the joining area 17 and upstream of the twisting device 23, the secondary thread ( 3), the device is configured. As the secondary yarn 3 is twisted together with the yarn yarn 1 and the decorative fiber 5c, the decorative fiber 5c is entangled with the yarn yarn 1. Alternatively, designability or functionality can be imparted to the design yarn 10 by applying a yarn having a different property from that of the main yarn 1 to the secondary yarn 3.

For such merging and twisting, an air nozzle 23 such as, for example, a swirling nozzle that imparts false twist to the yarn by causing the airflow to swirl may be used. According to the turning nozzle, the main and secondary yarns 1 and 3 are rotated, and the entanglement of the decorative fibers 5c with the main and secondary yarns 1 and 3 is promoted. This is advantageous in preventing the decorative fibers 5c from falling off. Instead of the swivel nozzle, a hollow spindle may be used, for example. Alternatively, or in addition to this, heating or the like may be applied.

The decorative fibers 5c will be entangled as if they are wound by passing through the air nozzle 23 together with the yarn yarns and the yarn yarns 1 and 3. The air nozzle 23 is only used to prevent the decorative fiber 5c from falling off, and it does not necessarily require collecting the yarns 1 and 3. The state of the yarns 1 and 3 and the decorative fiber 5c passing through the air nozzle 23 will be as shown in Fig. 6B, for example.

Referring again to FIG. 1 , the yarns 1 and 3 and the decorative fiber 5c joined together are guided to the entanglement device 25 . The bridging device 25 may include 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 to the yarn. Alternatively, instead of using the water imparting guide 27, the bridging nozzle 29 described later may be provided with a water nozzle. By applying a small amount of water to the threads, the intertwining of the threads 1, 3 and the decorative fiber 5c can be further strengthened.

The bridging device 25 includes an air nozzle such as the bridging nozzle 29 . Referring to FIG. 5 , a known bridging nozzle may be applied to the bridging nozzle 29 . The bridging nozzle 29 has a guide hole 41 through which yarn passes, and an air duct 43 communicating with the guide hole 41 . The air duct 43 is connected to an external blowing device such as a blower, and is narrowed at least on the guide hole 41 side, so that a relatively high-speed airflow A4 is blown into the guide hole 41. has been The airflow A4 blown into the guide hole 41 causes a relatively high-speed turbulent flow at its exit, which imparts entanglements to the yarns passing through the guide hole 41 .

Yarns 1, 3 and decorative fibers 5c to which water is applied pass through the entanglement nozzle 29, whereby the threads 1, 3 are bundled with each other and further entangled together with the decorative fibers 5c. become tightly entangled with each other, and thus, the design yarn 10 as shown in FIG. 6C is obtained.

Although the example using the bridging nozzle has been described above, an interlaced nozzle may be used instead, or a yarn processing device such as a hollow spindle or a combination of a friction twisting device and a heating device may be used. Alternatively, instead of or in addition to using such yarn processing means, heating or bonding may be used. As a heating means, a heater, a laser, and an ultrasonic generator can be illustrated.

Further, although an example in which false twist is applied to the yarn has been described above, yarn twist may be used instead of false twist. 2 shows an example of yarn twisting, and the twisting device 23b is a yarn twisting device, for example, a combination of a twister and a spindle. In this case, the spindle doubles as a winder. Even by thread twisting, of course, the decorative fibers 5c are firmly entangled among the yarns 1 and 3, so that the yarns 1 and 3 are more firmly bundled. Since the decorative fibers 5c can be tightly entangled in the thread 1 during twisting, the entanglement device 25 may be omitted.

Further, in this example, the yarn guide 23a can be provided downstream from the joining area 17 and upstream from the twisting device 23b. The thread guide 23a has only a function of guiding the main thread 1 and the auxiliary thread 3 so as to join the decorative thread 5, or even if it is accompanied by a configuration that turns or processes the yarn. do.

Referring again to FIG. 6C , the decorative yarn 10 according to the present embodiment has a relatively long feather-like structure with short cut decorative fibers. Each structure is feather-shaped, but since it is firmly intertwined with the main thread and the secondary thread, it does not easily fall off as a feather.

The size of these structures can be freely changed depending on the length of cutting the decorative threads, and also the spacing between structures adjacent to each other can be freely changed by the spacing of cutting the decorative threads. Needless to say, you can also change the size and spacing for each structure. Also, as already explained, since two or more decorative yarns can be used, for example, different colors can be used for each structure.

In the conventional manufacturing method of decorative yarn, in many cases, structures such as loops and slubs are formed by processing yarns of continuous long fibers, so that the ends of the fibers do not spread outward of the decorative yarn, so as in the present embodiment. cannot form long feather-like structures. Also, in the conventional manufacturing method, it is not possible to control the spacing between structures or the size of each structure very freely. According to this embodiment, these are easily realized. Further, according to this embodiment, different colors can be provided for each structure.

Although several embodiments have been described, it is possible to modify or transform the embodiments based on the content of the disclosure above.
