JP4943260B2 - Elastic decorative string - Google Patents

Description

  The present invention relates to a decorative string that can be used as, for example, watering, and more particularly, to a stretchable decorative string that has stretchability, can be easily attached and detached, and can be used as a band.

As water-stretching having elasticity, the one disclosed in Patent Document 1 below has been proposed.
This is a stretchable watering system in which a plurality of string-like objects formed by winding a thread around an elastic core are arranged in parallel. The winding of the yarn around the core is not integrated using an adhesive, but can be expanded and contracted simply by winding.

  However, in the stretchable watering having such a structure, since the deformation in which the cross-sectional area of the core changes with expansion and contraction occurs, the yarn may be displaced or returned, and the appearance may be impaired.

  Moreover, the thing of the following patent document 2 is disclosed as an accessory cord used for a necklace or a bracelet.

  This accessory cord is made by winding a sheath yarn made of a thermoplastic synthetic fiber around a core yarn made of an elastic yarn, and prevents fraying by heat welding.

  In the accessory cord having such a configuration, fraying is prevented, so that inconvenience such as slippage as in the case of the stretchable watering described above can be avoided, but a special sheath thread must be used. Although it is good for an accessory cord for passing a decorative member (accessory) such as the above, it lacks a decorative property to be used as a water draw. In addition, the use of special yarns is expensive.

  Therefore, the main object of the present invention is to provide a stretchable decorative string that can be used in various ways without causing an appearance to be lost along with expansion and contraction and having a high decorative effect.

  Means therefor include a stretchable core material, a primary covering material wound around the surface of the core material, a heat welding yarn attached onto the primary covering material, and the heat welding yarn. A stretchable decorative string having a secondary covering material wound thereon and heated to melt the heat-welded yarn after the secondary covering material is wound.

  The above-mentioned heat welding yarn is attached along, for example, along the length direction of the core material.

  By the welding of the heat welding yarn, integration is performed at the intersection of the primary covering material, the heat welding yarn, and the secondary covering material.

  For this reason, the independence of the covering material is high, and even when the core material expands and contracts, it is less affected. Further, deformation accompanying expansion and contraction of the core material is possible. Therefore, even if the elastic decorative string expands and contracts and the deformation that changes the cross-sectional area of the core material occurs, the basic positional relationship between the covering materials is maintained.

  As a result, the displacement and return of the covering material are suppressed, and the appearance can be maintained.

  Another means is a primary winding step of winding the primary covering material on the surface of the stretchable core material, a heat welding yarn attaching step of attaching a heat welding yarn on the primary covering material, Manufacture of stretchable decorative string having a secondary winding step of winding a secondary covering material on the welding yarn and a heating and melting step of heating to a temperature at which the hot welding yarn melts after the secondary winding step Is the method.

  As described above, according to the present invention, the secondary covering material is wound on the primary covering material, and the space between them is partially joined and integrated by the heat-welding yarn. Even if it expands and contracts, the appearance can be maintained without damaging the appearance due to the displacement of the covering material. A good appearance that is not inferior to that produced by knitting the outer peripheral part can be obtained.

  Moreover, since the thing of appropriate materials, such as a cotton thread, a synthetic fiber, a synthetic resin film, paper, a water draw, and a braid, can be used for a covering material, it can be set as the highly decorative thing which has a desired external appearance.

  Furthermore, since an adhesive can be made unnecessary in manufacturing, the manufacturing can be easily performed. In addition, there is no protrusion of the adhesive in the finished state, and it is possible to prevent the appearance from being damaged from this point.

An embodiment for carrying out the present invention will be described below with reference to the drawings.

  Further, the secondary covering material 51 is wound in a direction opposite to the winding direction of the primary covering material 31.

  In this case as well, the above-described heat-welded yarn 41 may be attached as appropriate, but it is preferable that the heat-welded yarn 41 extends along the length of the core member 21 as shown in the figure.

  Further, the secondary covering material 51 is wound in a direction opposite to the winding direction of the primary covering material 31.

  The decorative string 11 illustrated in FIG. 6 uses one type of covering material as the primary covering material 31 and one type of covering material as the secondary covering material 51. . A non-twisted yarn 34 is used for the primary covering material 31. As the secondary covering material 51, a water draw 55 is used. As the water draw 55, an existing one can be used, and for example, it is preferable that a paper web or the like is colored or a tape or the like is wound. When the tape is wound, it may be wound with one color tape as shown in FIG. 6 (a), but the glossy color tape 55a as shown in FIG. If it is wound so that it appears, a beautiful appearance can be obtained.

  That is, first, the untwisted yarn 34 as the primary covering material 31 is densely wound around the surface of the core material 21 (primary winding step). Thereafter, the heat-welding yarn 41 is attached on the primary covering material 31 (heat-welding yarn attaching step), and further, the water draw 55 as the secondary covering material 51 is roughly wound (secondary). Winding process). It may be wound tightly. Then, it manufactures by heating to the temperature which the heat welding thread | yarn 41 fuse | melts (heating-melting process).

  In this case as well, the above-described heat-welded yarn 41 may be attached as appropriate, but it is preferable that the heat-welded yarn 41 extends along the length of the core member 21 as shown in the figure.

  Further, the secondary covering material 51 is wound in a direction opposite to the winding direction of the primary covering material 31.

  The decorative string 11 illustrated in FIG. 7 is an example in which two types of two covering materials are used as the primary covering material 31 and two types of covering materials are used as the secondary covering material 51. . The primary covering material 31 is wound in this order using a water pull 35 and a non-twisted yarn 34. The secondary covering material 51 is wound in this order using a non-twisted yarn 54 and a decorative tape 53 such as a metal vapor-deposited tape.

  That is, the non-twisted yarn 34 is wound after the water-drawing 35 as the primary covering material 31 is tightly wound around the surface of the core material 21 (primary winding step). After that, a heat welding yarn 41 is attached on the primary covering material 31 (heat welding yarn attaching step), and further, a non-twisted yarn 54 as the secondary covering material 51 is roughly wound thereon, The decorative tape 53 is wound so as to be placed at an intermediate position in the width direction of the untwisted yarn 54 (secondary winding step). Then, it manufactures by heating to the temperature which the heat welding thread | yarn 41 fuse | melts (heating-melting process). Since the untwisted yarn 54 of the secondary covering material 51 is wound roughly and the decorative tape 53 is placed thereon, the surface of the primary covering material 31 can be visually recognized from between the untwisted yarn 54, such as water pulling 35. Depending on the appearance, combined with elasticity, you can get a novel design.

  In this case as well, the above-described heat-welded yarn 41 may be attached as appropriate, but it is preferable that the heat-welded yarn 41 extends along the length of the core member 21 as shown in the figure.

  In this case as well, the above-described heat-welded yarn 41 may be attached as appropriate, but it is preferable that the heat-welded yarn 41 extends along the length of the core member 21 as shown in the figure.

  Further, the secondary covering material 51 is wound in a direction opposite to the winding direction of the primary covering material 31.

  The decorative string having the steps as described above is manufactured using an appropriate apparatus.

  In the decorative string 11 configured in this manner, as schematically shown in FIG. 8, the decorative string 11 extends in the length direction of the core material 21 between the primary covering material 31 and the secondary covering material 51. Since the heat-welding yarn 41 interposed between the two melts and adheres, partial adhesion is performed at the portion where these three components are polymerized. In the figure, reference numeral 42 denotes an adhesive portion.

  Since the entirety is not bonded, the primary covering material 31 and the secondary covering material 51 are appropriately deformed as the core material 21 expands and contracts, so there is no hindrance to expansion and contraction. For this reason, free expansion and contraction is possible. Moreover, even if the covering material is partially stretched after being stretched once, the covering materials are partially bonded to each other. Due to appropriate integration between the covering materials, independence from the core material 21, etc., the position of the covering material Misalignment is unlikely to occur and cannot be reversed. As a result, the desired decorativeness can be maintained without impairing the appearance.

  Further, since no adhesive is used in the production, the production can be easily performed with an appropriate apparatus. In addition, there is no protrusion of the adhesive in the finished state, and it is possible to prevent the appearance from being damaged from this point.

  Furthermore, since the cover material can be made of an appropriate material such as cotton yarn, synthetic fiber, synthetic resin film, paper, water draw, braided string, etc., it can be made highly decorative with a desired appearance. Moreover, since the number and kind of the primary covering material 31 and the secondary covering material 51 can also be set freely, compared with what manufactured the outer peripheral side, various variety of decorative strings can be obtained. it can. The above effect is also enhanced by roughly winding the covering material located on the upper side to expose or show the lower covering material.

  Moreover, if the paper twisted string 33 or the water pulling 35 is used for the primary covering material 31, the core material can be hardened as schematically shown in FIG. 9, or an appropriate frictional resistance is obtained. Therefore, it is possible to obtain the decorative string 11 that is more difficult to remove. Further, the presence of the twisted paper string 33 has an effect of concealing the core material 21.

  The above configuration is one form for carrying out the present invention, and other configurations can be adopted.
