Description

  The present invention relates to a shape holder used for clothes and handicrafts, and used for binding materials.

  Conventionally, wire is not used for binding materials that require plastic deformation that does not return to its original shape when bent or twisted (for example, used to close the mouth of a bag containing food). It was mainly used. Also, in handicrafts and the like, when making artificial flowers or the like, a stem made by winding a paper tape around a wire is used for the stem part. As the clothing that needs to maintain its shape, there is known a clothing in which the shape is woven by using a wire or the like as a warp.

  Recently, polyolefin-based plastic wires have been proposed as an alternative to such conventional wires. For example, JP-A-61-282416 (Patent Document 1), JP-A-2-293407 (Patent Document 2), JP-A-7-238417 (Patent Document 3) and the like have been proposed. Such plastic wire is actually commercially available.

Further, JP 2003-205565 (Patent Document 4) does not use the core material as it is, but sandwiches a core material made of a thermoplastic resin between the heat-fusible films, and the outer heat-fusible film. A molded sheet in which the core material is coated by fusing the upper and lower layers is disclosed.

However, conventional wires and plastic wires as disclosed in Patent Documents 1, 2, and 3 are often used as they are, and the range of use is limited. For example, it is often used in a state where it cannot be seen from the outside, such as in a mask. Moreover, since the wire can be seen from the outside when the wire is put in the fabric, there is a problem that the color is different from other yarns and the appearance is bad.

  Since the molded sheet disclosed in Patent Document 4 cannot be stably bound as it is when twisted and tied with a plastic wire or the like by an automatic binding machine or the like, the plastic wire made of a thermoplastic resin is formed into a sheet-like shape. By being sandwiched between heat-fusible films and covered with a heat-fusible film, it can be stably bound by an automatic binding machine. However, such a thing is good for making a binding tool, but because of its shape (shape in which the core part swells and the flat part expands to the left and right in the cross section), and the range of use Is limited. In addition, the color of the molded sheet is determined by the color of the heat-fusible film, and it is difficult to change the color of the heat-fusible film in various shades (especially light shades) due to costs. It is.

  The present invention solves such problems and can be widely used not only as a binding material but also as a clothing material and a handicraft material, and can be used without adversely affecting the appearance of clothing. An object of the present invention is to provide a simple shape holder.

  It is another object of the present invention to provide a manufacturing method that can easily manufacture shape holders of various shades.

The present invention is a shape holding body composed of a core material and a sheath thread, the core material is composed of a linear or tape-shaped plastically deformable plastic material, the sheath thread is composed of an inner covering thread and an outer covering thread, The inner coated yarn and the outer coated yarn are crimped bulky processed yarns, and the inner coated yarn and the outer coated yarn are wound around the core material in opposite winding directions with a twist number of 1500 T / m or more, respectively. The above-mentioned object is achieved by a shape holding body characterized by covering the core material.

  In this case, it is preferable to use a linear plastic deformable plastic material having a diameter of 0.4 mm or more or a tape-shaped plastic deformable plastic material having a thickness of 0.2 mm or more and a width of 1 mm or more as the core material.

  The present invention also provides a covering device in which hollow spindles are provided in two upper and lower stages, using a linear or tape-shaped plastically deformable plastic material as a core material, and extending the hollow shaft of the hollow spindle without stretching the core material. The inner shape of the crimped bulky processed yarn and the outer coated yarn are supplied from the bobbins of the hollow spindles and wound around the core material with a twist number of 1500 T / m or more. The object is achieved by a method for manufacturing a body.

  In the present invention, a plastically deformable plastic material is used as a core material, and a double coated with an inner coated yarn made of a crimped bulky processed yarn and an outer coated yarn made of a crimped bulky processed yarn thereon. Since the coated yarn is wound around the core material with a twist number of 1500 T / m or more to cover the core material, the core material itself is not visible from the outside. Therefore, by changing the color of the covering yarn used as the sheath yarn, etc., it is possible to obtain a shape holding body of various shades irrespective of the color of the core material (usually white). For this reason, the use range of this shape holding body of this invention becomes a very wide thing.

  According to the present invention, the core material is doubly covered with the inner covering yarn and the outer covering yarn and is covered with a twist number of 1500 T / m or more, so that the covering yarn is not displaced. When the core material is thick, the two inner coated yarns and the outer coated yarn are wound together so that the coated yarn is not further displaced.

  Further, according to the present invention, the covering device provided in the upper and lower two stages passes the hollow shaft of the hollow spindle without extending the core material, and the coated yarn is wound around the core material. Unlike the case where it is wound by hand, shape holders of various shades can be easily manufactured.

  Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. Fig.1 (a) shows one Example of the shape holding body of this invention, and is a front view which has shown the state which unfolded the covering yarn, FIG.1 (b) is a cross section of what was shown to (a) It is sectional drawing which showed typically.

  The shape holding body 1 of the present invention is composed of a core material 11, an inner covering yarn 12 and an outer covering yarn 13. The core material 11 is made of a linear or tape-shaped plastically deformable plastic material. If the linear core material is too thin, it deforms even if a slight force is applied, and the shape retainability deteriorates. Therefore, it is preferable to use a material having a diameter of 0.4 mm or more (plastic deformation) Assuming that the conductive plastic material is high-density polyethylene, a linear core material having a diameter of 0.4 mm is about 1200 dtex in terms of dtex). In addition, it is preferable that the tape-shaped core material has a thickness of 0.2 mm or more and a width of 1 mm or more from the viewpoint of shape retention (Note that the plastically deformable plastic material is high-density polyethylene. The tape-shaped core material having a thickness of 0.2 mm and a width of 1 mm is about 1900 dtex).

  The plastically deformable plastic having shape retention is as proposed in Patent Document 1, Patent Document 2, or Patent Document 3 described above. In addition, as a linear plastically deformable plastic material, for example, there is a material commercially available as “Techno Roto” (registered trademark) from Mitsui Chemicals, Inc. As a tape-like plastically deformable plastic material, there is one commercially available as “Forte” (registered trademark) from Sekisui Chemical Co., Ltd. Such a core material can be used as the core material of the present invention.

  Both the inner covering yarn 12 and the outer covering yarn 13 use crimped bulky yarns such as woolly nylon yarns. In this case, when the core material 11 is thin, the denier of the crimped bulky processed yarns 12 and 13 may be thin, for example, 70 denier (about 80 dtex) or more, but when the core material 11 has a diameter of 0.7 mm, it is 140 denier. It is preferable to be about (about 155 dtex). When the diameter of the core material 11 is larger, it is preferable to use crimped bulky processed yarns 12 and 13 having a larger denier number. Note that a single crimped bulky processed yarn may not have the desired number of deniers, but a plurality of crimped bulky processed yarns (for example, two crimped bulky processed yarns) may be aligned to obtain the desired number of deniers.

  The inner covering yarn 12 and the outer covering yarn 13 are wound around the core material 11 at a winding number of 1500 T / m (that is, 1500 turns per meter) or more. It is preferable to increase the number of twists per meter as the diameter of the core material 11 increases. By doing so, the core material can be completely covered and the covered yarn can be made difficult to slip. Each of the inner covering yarn 12 and the outer covering yarn 13 may be a single yarn, or may be wound in a state in which two or more yarns are aligned. In particular, when the diameter and width of the core material 11 are wide, it is more difficult for the coated yarns 12 and 13 to be wound around the core material than two coated yarns 12 and 13 are aligned, as compared to winding one yarn. Become.

  Next, the manufacturing method of the shape holding body of this invention is demonstrated based on FIG. FIG. 2 shows an embodiment using a covering device in which hollow spindles are provided in two upper and lower stages. First, the core material 11 is sent out from the package 10 around which the core material 11 is wound. The core 11 travels through the hollow shaft 21 of the lower hollow spindle 20 that is driven by the drive belt 2, and the inner coated yarn 12 drawn from the package 22 placed on the hollow spindle 20. Is further wound and travels through the hollow shaft 31 of the upper hollow spindle 30. The outer covering yarn 13 is pulled out from the package 33 placed on the upper hollow spindle 30, and the outer covering yarn 13 is wound on the core material 11 around which the inner covering yarn 12 is wound. It becomes the shape holding body 1 and is wound on the package 40 driven by the driving roller 3. In this case, until the core 11 is pulled out of the package 10 and wound around the package 40, the traveling speed is the same, and the core 11 is not stretched and is allowed to travel while maintaining its length.

  The lower hollow spindle 20 and the upper hollow spindle 30 are driven by the driving device 2, respectively, and the rotational speed of the hollow spindle is determined in relation to the traveling speed of the core material 11, and the twist number is 1500 T / m or more. It is rotated at such a rotational speed.

  The shape holder 1 wound on the package 40 may be cut into a length suitable for use. The shape holder 1 of the present invention can be used, for example, in clothing by inserting or sewing it into the edges of pocket mouths, heels, cuffs, hems, plackets, etc. It can be used to maintain a bent state.

  Since the shape holding body 1 of the present invention can change the color of the coated yarn in various ways, the design can be changed by matching the color of the yarn with the color of the garment body or conversely.

  As other uses, for example, the shape holding body of the present invention can be used for a part of a bag, a bag, footwear, a hat, or the like, and the shape can be adjusted. Also, interesting things can be made by making various shapes of bags and hats mainly using the shape holder of the present invention. Furthermore, it can be used in the same manner as those conventionally used for wires and plastic wires.

  A twin yarn made of Mitsui Chemicals' “Techno Roto” diameter 0.7 mm is used as the core material 11 and two 70 deniers of wooly nylon (crimped bulky processed yarn) are twisted as the inner covering yarn. One (140 denier) was used. In addition, one double yarn obtained by twisting two 70 deniers of wooly nylon was used as the outer covering yarn. The lower spindle rotation speed was 12000 rpm. The upper spindle rotation speed was set to 10,000 rpm. The number of twists in this state was 1800 T / m. The obtained product is a comparatively thin shape holding body, and is a material suitable for use in making a frill or the like for use in hand trimming, for example, at the edge of clothing.

  “Techno Roto” manufactured by Mitsui Chemicals, Inc. having a diameter of 1.1 mm was used as the core material. As the inner coated yarn, one double yarn (140 denier) in which 70 denier of wooly nylon was twisted was used. As the outer covering yarn, a double yarn (280 denier) obtained by twisting two twisted 70 denier nylon yarns was used. The rotational speed of the lower spindle was 12000 rpm, and the upper rotational spindle was 12000 rpm. The number of twists was 2500 T / m.

  In this product, the diameter of the core material was thicker than that of Example 1, but the two coated yarns of the outer side were aligned, so that the coated yarn did not shift in the product.

  A tape-shaped plastically deformable plastic material (“Forte” from Sekisui Chemical Co., Ltd.) having a thickness of 0.4 mm and a width of 2.5 mm was used as the core material. As the inner coated yarn, two 70 denier yarns twisted into a double yarn were used. Similarly, two double yarns obtained by twisting two 70 denier wooly nylon yarns were used as the outer covering yarn. The lower spindle rotation speed was 12000 rpm, and the upper spindle rotation speed was 12000 rpm. In this case, the number of twists was 3000 T / m.
