Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multi-thread yarn for bundled use of a plurality of yarns, for example, a wig or artificial hair used for artificial hair transplantation, which is supplied in a pre-bundle state.

[0002]

[Prior art]

 When a plurality of yarns are used in a bundle, the bundled yarns are usually supplied as individual pieces cut into a certain size to be used. For example, in the case of artificial hair, the required number of threads (artificial hair) to be used at one place are arranged in a plane on a backing sheet and fixed with sewing thread or the like.

[0003]

[Problems to be solved by the device]

 In the conventional method in which the bundled yarns are independently supplied for each unit, it is difficult to handle the yarns in a mechanically continuous manner. Further, artificial hair or the like having one end bundled and fixed has a drawback that a plurality of threads are easily entangled.

In order to bundle a plurality of yarns and mechanically handle the yarns, it is preferable to wind the yarns around a winding tool such as a spool and supply the yarns. However, when a plurality of yarns are bundled without being twisted, various difficulties are involved in handling the bundled state as a single yarn (multi-thread yarn). For example, in the state of just bundling, it does not form a body as a single thread, so it has drawbacks such as being easily entangled in the winding tool and unwinding itself. Even if a plurality of yarns are bundled and wound up on a winding tool, if they are mechanically paid out, if one of the multiple threads is cut, this is a winding tool, etc. It can not be handled efficiently because it is entangled with.

In order to solve this problem, it is possible to twist a plurality of yarns to some extent. However, even in this case, when one yarn is cut, there still remains a drawback that the yarns are easily entangled, and the yarns have a peculiar shape. It is not suitable for use because of In view of such a point, the present invention is devised so that a multi-thread yarn obtained by bundling a plurality of yarns can be mechanically handled as one yarn.

[0006]

[Means for Solving the Problems]

 A plurality of yarns are bundled to form a multi-thread yarn, and the multi-thread yarn joins the plurality of yarns at a predetermined interval P to form an integrated connecting portion 2. The connecting portions 2 are arranged in parallel on the same plane and connected in a flat state according to the purpose and use of the yarn to be used.

[0007]

[Action]

 The multi-thread yarns that are integrally connected at a predetermined interval can be handled as a single yarn as a whole without the multiple yarns 1 and 1 coming apart due to the presence of the connecting portions 2 and 2. Becomes When this multi-strand yarn is mechanically paid out and used, even if one yarn 1 that composes the multi-strand yarn is cut, it is entangled within the range up to the next joint, and it is paid out one after another. No influence is exerted beyond the joint portion 2 of the multi-thread yarn. Further, the cut yarn is sent to the other side due to the existence of the connecting portion 2, and it is not entangled with the winding tool or the like. .

【Example】

 Hereinafter, embodiments of the multi-thread yarn of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a state in which a multi-thread yarn is wound around a winding tool 3. For the multi-thread yarn, a plurality of yarns, for example, in the case of artificial hair, a dozen or more acrylic monofilaments having a size of about 80 microns are bundled, and the bonding portion 2 is arranged at a predetermined interval, for example, twice the length required for hair.

In order to bond a plurality of yarns at the joint portion 2, they can be joined together by an adhesive, when the yarns are thermoplastic synthetic resin fibers, by heat welding, molding or any other means.

FIG. 2 shows an example of a cross section of the coupling portion 2. In FIG. 2, (a) shows an embodiment in which a plurality of threads are arranged in parallel on the same plane and integrated by an adhesive 4, (b) shows a plurality of threads arranged in parallel on the same plane, An example in which they are integrated by heat welding is shown. In the case of artificial hair, it is preferable to combine them in a planar arrangement as shown in (a) and (b) of Fig. 2, but depending on the application, they may be bundled in a round shape as shown in (c). It may be combined in the state.

FIG. 3 shows an embodiment in which the multifilamentary yarn of the present invention is used as artificial hair on the wig cloth 5. In order to obtain artificial hair of length L, the space between the connecting portions 2 and 2 is to be obtained. The interval P is set to be approximately twice the size L, and is folded in two and bound to the wig cloth 5 as shown in FIG. 3 (a). After binding to the wig ground 5, the connecting portions 2 and 2 are cut off, and as shown in FIG. 3 (c), twice the number of the bundled threads are fixed to the wig ground 5 as artificial hair. . In the case of artificial hair for artificial hair transplantation, the folded back part of the multi-thread yarn is subjected to the necessary treatment for hair transplantation.

As shown in FIG. 3 (a), if the multi-thread yarn is handled with the connecting portions 2 and 2 left at both ends, the yarn in a bundled state may be scattered. Instead, they can be treated as if they were a single thread.

On the other hand, as shown in FIG. 3B, it is possible to leave the coupling portion 2 only at one end and use it. In this case, one end can be aligned and fixed to a mount or the like as in the conventional case, and the same handling can be performed. In any case, when the connecting portion 2 is cut off after processing, the state shown in FIG. 3 (c) is obtained.

The present invention is not limited to the artificial hair providing means shown in the embodiments, but can be widely used for a bundle of a plurality of yarns. In practicing the present invention, it is preferable that the distance P between the coupling portions 2 and 2 be a length required for bundling and use, or an integral multiple thereof. However, if the interval P is too large, the entanglement of the yarn cut in the interval P cannot be ignored. Therefore, it is more preferable that the interval P does not become so large in relation to the thickness of the yarn.

Further, the thin yarn forming the multi-thread yarn may be not only the single fiber shown in the embodiment but also a twisted yarn in which the yarn 1 itself is thin.

[0016]

[Effect of device]

 According to the multi-thread yarn of the present invention as defined in claim 1, it is possible to wind this around a winding tool and mechanically feed it out for processing. If the yarn is simply wound into a winding tool in a state of being bundled, when one thread is cut, the thread is wound around the winding tool, and continuous processing cannot be performed. However, even if a single thread is cut, the cut thread does not get entangled with the take-up tool, etc. and cannot be reused without discarding a large amount of thread. If only the part where the thread is located is cut between the joints, it can be restarted immediately.

Further, the multi-strand yarn of the present invention is a single yarn that does not become entangled or entangled with each other even if it is a bundled yarn that does not twist due to the presence of the joint portion. Mechanical handling is possible.

According to the second aspect of the present invention, since the two-dimensionally aligned state is maintained between the joining portions, it is necessary to use a plurality of threads aligned in a plane. It can also be used as it is unrolled from the winding tool. In addition, there is little possibility that multiple yarns will become entangled with each other, and even when wound on a winder, they can be wound up neatly without being bulky, as if continuous thin yarns were wound in an aligned state without gaps. it can.
