Description

  The present invention relates to a molding using a metal wire as a core and a method for manufacturing the molding.

  In general, the molding is made by twisting a yarn that is a decorative portion between a core yarn and a core pressing yarn. Here, the flower yarn is required to have a decorative property mainly to determine the appearance of the mall. On the other hand, the core yarn is required to have flexibility and strength such as bending in addition to firmly holding the flower yarn so as not to come off. For this reason, the conventional molding uses, for example, hairs and fibers dyed in flower yarn and wire for core yarn.

  By the way, the flower yarn that is simply pinched and twisted between the core yarn and the core presser yarn easily falls off when rubbed or caught. Therefore, a technique relating to molding has been developed, in which a flower yarn is bound to a core yarn with a heat-sealing yarn or fused (see Patent Document 1).

JP 2000-54237 A

  However, even if a conventional molding using a wire for the core yarn has flexibility and strength such as bending with the wire, the portion where the flower yarn is tied to the wire with the heat-sealing yarn or the portion fused is bent. Since the resistance is low, there is a problem that the yarn is easily removed. This is because the part where the flower yarn is tied to the wire with the heat-welding yarn is likely to loosen mainly due to the elongation or deformation of the wire, and the part where the flower yarn is fused to the wire with the heat-welding yarn is mainly used. One reason is that the wire is easily peeled off from the wire due to the elongation or deformation of the wire. Therefore, the molding using wire for the core yarn has a problem in repetition of bending and the like.

  In addition, the molding using a wire for a conventional core yarn has a problem that the decorativeness of the flower yarn is deteriorated depending on the use because the metal color of the wire is added to the appearance.

  The present invention has been made in view of the above problems, and provides a molding using a metal wire as a core part and a method for manufacturing the same, which suppresses the falling off of the flower yarn and does not impair the decorativeness of the flower yarn. Is the main technical issue.

  The molding according to the present invention includes two core yarns, a flower yarn, and a heat fusion yarn, the core yarn is a metal wire covered with fibers, and the outer periphery of the core yarn is coiled with the heat fusion yarn. The wound yarn is sandwiched between the core yarns and is fused to the core yarn with a heat fusion yarn.

  With this configuration, the influence of elongation and deformation of the metal wire is reduced by the fiber covering the metal wire, and the flower yarn can be firmly fused to the fiber to prevent the flower yarn from falling off. In addition, since the metal wire is covered with a fiber so that the metal color of the metal wire is not visible from the outside, it is possible to prevent the decoration of the flower yarn from being damaged by the metal color of the metal wire.

  The metal wire of the molding according to the present invention may be any metal wire such as iron, stainless steel or alloy, but is preferably a copper wire. Copper wires are softer and more durable than metal wires such as wires, and are therefore suitable for being used by repeatedly deforming a molding.

  At least one of the fibers and the yarns of the molding according to the present invention may be acrylic fibers or polyester fibers that can be cationically dyed. In this specification, the acrylic fiber refers to a chemical fiber containing acrylonitrile as a raw material. Therefore, the acrylic fiber of the present specification is a fiber composed of a linear synthetic polymer containing 85% or more of acrylonitrile group repeating units by mass ratio or 35% or less and less than 85% of acrylonitrile group repeating units by mass ratio. It means that it contains regardless of the kind etc. which consist of a linear synthetic polymer to contain. Acrylic fibers are more resistant to friction and tension than wool, have excellent light resistance compared to other synthetic fibers, and can have vivid colors. Therefore, the acrylic fiber is suitable for a decorative part of the mall, that is, a fiber that covers the flower thread or metal wire of the mall. Here, cation dyeing means dyeing with a basic dye, that is, a dye that becomes a cation (cation) in an aqueous solution. In particular, a basic dye having excellent dyeability with respect to acrylic fibers is called a cationic dye.

  The fibers and flower yarns of the molding according to the present invention may have the same color. In this way, a mall having a sense of unity in color is created.

  In the molding method according to the present invention, first, two metal wires are coated with fibers without any gaps, and further, heat-sealed yarn is wound around the metal wires coated with the fibers. Next, two metal wires are arranged in parallel, and a flower yarn is arranged between them, and the metal wires are twisted together while sandwiching the flower yarn. Thereafter, these metal wires are heat-treated to fuse the heat-sealing yarn to both the fiber and the flower yarn. As a result, it is possible to obtain a molding using a metal wire in the core part, which prevents the yarn from coming out and jumping out and does not impair the decorativeness of the yarn.

  In the molding according to the present invention, the metal wire of the core wire is coated with the fiber, and the flower yarn is fused to the fiber with the heat-sealing yarn, so that the yarn loss due to deformation such as bending of the metal wire is suppressed. be able to. Moreover, since the molding according to the present invention covers and hides the metal color of the metal wire with the fiber, the decorativeness of the flower yarn is not impaired.

(the mall)
FIG. 1 is a perspective view showing a configuration of a molding before twisting and heat-treating. As shown in FIG. 1, the molding 1 includes a metal wire 2, a covering yarn 3, a heat fusion yarn 4, and a flower yarn 5. A metal wire 2 (hereinafter, this metal wire is referred to as a “coated metal wire”) around which the coated yarn 3 is wound without a gap is further wound with a heat-sealing yarn 4 in a coil shape (hereinafter referred to as this metal wire). The metal wire is referred to as “coated metal wire with heat-bonding yarn”. Here, in this specification, being wound in a coil shape means that the pitch width is longer than that of being densely wound without a gap and the winding is sparsely wound. The thickness of the coated metal wire is preferably about 0.05 [mm] to 3 [mm]. The coated metal wire may be one in which a material such as a fiber is coated on the metal wire 2 instead of the coated yarn 3. Further, the coated metal wire may be one in which a material such as a plurality of coated yarns and resins, or a combination thereof, is coated on the metal wire 2. Further, the coated yarn 3 and the heat fusion yarn 4 may be wound around the metal wire 2 and then tied to each other, or may be fixed with an adhesive. The coated metal wire may be partially or wholly fixed using an adhesive between the metal wire 2 and the coated yarn 3.

  In FIG. 1, the mall 1 uses two covered metal wires with heat-bonding yarn as a basic configuration, but a larger number may be used. As shown in FIG. 1, the flower yarn 5 is arranged between two coated metal wires arranged in parallel. The molding 1 is completed by twisting the coated metal wire while sandwiching the flower yarn 5 between the coated metal wires from the state of FIG. 1 and fusing the heat-sealed yarn 4 to the coated yarn 3 and the flower yarn 5 by heat treatment. In this case, the flower yarn 5 of the molding 1 is fused not to the metal wire 2 but to the covering yarn 3, so that it is difficult to come out of the covering yarn 3 even when the metal wire 2 is stretched or deformed. Moreover, since the coated yarn 3 is coated on the metal wire 2 without a gap, the metal color of the metal wire 2 is not visible on the exterior of the molding.

  The metal wire 2 can use materials such as iron, copper, stainless steel, and alloys. Various fibers can be used for the covering yarn 3 and the flower yarn 5. Specifically, the covering yarn 3 and the flower yarn 5 are: rayon, acrylic, acrylic, nylon, long fibers such as polyester including those that can be cationically dyed, short fibers, fibers modified for cationic dyeing, natural fibers , Composite fiber and synthetic fiber. Further, as the covering yarn 3 and the flower yarn 5, paper slit tape yarn, flat yarn, lame yarn and the like can also be used.

  The covering yarn 3 and the flower yarn 5 are preferably made of the same material with the same color. In this way, a mall 1 with a sense of unity can be obtained. Further, it is preferable to select the covering yarn 3 and the flower yarn 5 that are easily fused to the heat-sealing yarn 4.

  FIG. 4 is a diagram illustrating an example of a mall. FIG. 4A shows a photograph of the mall, and FIG. 4B schematically shows the mall of FIG. 4A. In FIG. 4B, a part of the configuration is simplified for easy understanding of FIG. Specifically, FIG. 4 (b) mainly reduces the number of flower yarns 5, omits the fusion layer in which the heat fusion yarn 4 is fused to the yarn 3 and the flower yarn 5 by heat treatment, A portion where two metal wires 2 coated with 3 are twisted is exposed. FIG. 4 shows two moldings 1, one molding 1 is closed by twisting the metal wire 2 at the tip, and the other molding 1 has the metal wire 2 and the covering yarn 3 at the tip. It has been solved. As can be seen from FIG. 4, since the coated yarn 3 is covered with the metal wire 2, the metal color of the metal wire 2 cannot be visually recognized from the outside. A large number of the flower yarns 5 are sandwiched between the metal wires 2 covered with the covering yarn 3, and serve as a decorative portion of the molding 1.

  Since the molding 1 has the flower yarn 5 fused to the covering yarn 3 instead of the metal wire 2, it is possible to reduce the influence of the elongation and deformation of the metal wire 2 and to prevent the flower yarn 5 from coming off. In addition, the molding 1 can be used for a desired decoration because the coated yarn 3 is covered with the metal wire 2 and the metal color of the metal wire 2 is not visible in appearance.

(Mall manufacturing method)
Below, the manufacturing method of a mall is demonstrated.
(1) Prepare two metal wires, a covering yarn, a heat-sealing yarn, and a flower yarn. At this time, it is preferable that the covering yarn and the flower yarn have the same color and the same material in order to make the molding have a sense of unity and simplify the selection of the heat fusion yarn. As the covering yarn and the flower yarn, those that are preliminarily dyed in a predetermined color may be selected, or they may be dyed at arbitrary points in time. As the heat fusing yarn, a yarn having a melting point lower than that of either the covering yarn or the flower yarn and a material that is easily fused to both the covering yarn or the flower yarn are selected. For example, when both the covering yarn and the flower yarn are acrylic fibers, it is preferable to use low-melting nylon or the like as the heat-sealing yarn.

(2) Wrap the coated yarn around the two metal wires without any gaps.
FIG. 2 is a diagram in which a metal wire is covered with a thread. As shown in FIG. 2, the coated metal wire 6 has the coated yarn 3 wound around the metal wire 2 without a gap. This winding may be performed in any manner as long as there is no gap such as multiple winding. Moreover, when covering the metal wire 2 with a material such as a fiber without a gap, the covered portion may have various structures such as a multilayer structure.

(3) A heat-sealing yarn is wound around each metal wire of (2) in a coil shape.
FIG. 3 is a view in which a heat-sealing yarn is wound around a metal wire covered with a yarn. The coated metal wire 7 with the heat-sealing yarn is obtained by winding the heat-sealing yarn 4 around the coated metal wire 6 shown in FIG. 2 in a coil shape. This winding may be performed so long as the heat-sealing yarn 4 is in contact with both the covering yarn 3 and the flower yarn used in the next step.

(4) Two metal wires of (3) are arranged in parallel and a flower thread is arranged between them. A space for crossing the metal wires of (3) alternately to sandwich the flower yarn may be provided as appropriate, and the flower yarn may be inserted into the space. Then, the coated metal wires are twisted together while the flower yarn is sandwiched between the coated metal wires.
(5) Thereafter, the heat-sealed yarn is fused to both the flower yarn and the coated yarn by heat treatment. A mall is obtained by the above procedures (1) to (5).

(Example)
Below, the Example of the manufacturing method of a mall is shown.
(A) First, an acrylic long fiber thread is wound around a 0.4 [mm] copper wire with a Italy type covering machine like a horizontal winding without a gap to obtain a coated metal wire. Two coated metal wires are prepared.
(B) Next, each coated metal wire is dyed red.
(C) Next, a heat-welded yarn (for example, Elder (registered trademark), manufactured by Toray Industries, Inc.) is wound around the coated metal wire in a coil shape to obtain a coated metal wire with a heat-welded yarn.
(D) Next, on the molding machine, the coated metal wires with heat-bonding yarns are arranged in parallel, and the yarns of acrylic long fibers dyed in red are arranged therebetween.
(E) Next, the coated metal wire with the heat fusion yarn is twisted together while the flower yarn is sandwiched between the coated metal wires with the heat fusion yarn by a molding machine.
(F) Next, the twisted metal wire obtained in (e) is heated with a heater. As a result, the heat fusion yarn is fused to both the coated yarn and the flower yarn to complete the molding.

  Copper wires are softer and more resistant to deformation than iron wires used in conventional wires. Therefore, the molding obtained in the above embodiment has durability against deformation as compared with the molding using the conventional wire, and can be repeatedly used by changing flexibly. In addition, workability is improved by using this mall. In addition, since the heat fusion yarn is fused to the flower yarn and the covering yarn in this molding, it is possible to reduce the influence of the elongation and deformation of the copper wire when the molding is deformed, and to prevent the yarn from falling off. . In addition, in this molding, since the red acrylic long fiber is covered with a metal wire without a gap, the metal color of the metal wire cannot be seen from the outside. Furthermore, since this molding uses a long red acrylic fiber for the flower yarn as in the case of the covering yarn, it can be used for decoration as a whole having a uniform sense of acrylic in red.

  Since the above-described molding method is simply wound, twisted, heated, and dyed as necessary, it does not require a large machine and can be carried out manually. Therefore, anyone can easily get a mall.

  The mall according to the present invention can be used in various decorative fields than conventional malls. Therefore, the present invention has a great industrial applicability as an improvement in the durability of the mall and expansion of the use of the mall.
