Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminescent decorative textile using an optical fiber having local light leakage portions distributed in the length direction.

[0002]

2. Description of the Related Art FIG. 5 is a plan view of a conventional luminous ornament of the type disclosed in, for example, Japanese Utility Model Laid-Open No. 2-15398. In the figure, reference numeral 1 is an optical fiber, and a plurality of optical fibers are bundled at one end, the other portion 2 is entwined in a braided shape, and the light source 3 is fixed so as to face the one end.

FIG. 6 is an axially enlarged cross-sectional view of the optical fiber 1. The optical fiber 1 is provided with a core 101 made of a material having a high transparency and a high refractive index, and is provided so as to cover the outer peripheral surface of the core 101 and has a high transparency. However, the clad 102 is made of a material having a lower refractive index than the core 101.

When the light L is made incident from one end of the optical fiber 1, the light L becomes the core 101 and the clad 10.
It is well known that the total reflection is repeated at the boundary surface 103 between the two and exits from the other end with substantially no loss, and if the cladding 102 is partially scratched as shown by an imaginary line. It is also well known that the total reflection at that portion is broken and a light leakage portion 104 is formed from which light leaks to the outside as shown by a virtual line.

FIG. 5 uses an optical fiber 1 having such local light leakage portions distributed in the length direction (axial direction). Light from the light source 3 is leaked from the light leakage portion 104 to the outside. By doing so, it is used as a light-emitting decoration. The Japanese Utility Model Laid-Open No. 2-15398 teaches that the optical fiber 1 has a woven structure.

[0006]

Since a long and wide woven fabric can be obtained by using a woven structure, it can be used as a large-sized light-emitting decorative body as it is or cut into a necessary size for various decorative uses. Although it can be used, when it is formed into a fabric using an optical fiber, the surface of the optical fiber is smooth and the optical fiber tends to slip out of the fabric and become a defective product. There is a problem that the weaving structure of the cutting portion is broken. In addition, it is necessary to apply tension to the warp during the weaving operation, but the optical fiber may be cut at the light leak part under the tension, and it is practical to connect the cut part even if it is cut in this way. It was impossible and there were various problems such as defective products.

The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a luminescent decorative fabric which can be easily manufactured with stable quality.

[0008]

In order to achieve the above-mentioned object, the luminous decorative fabric of the present invention comprises at least a part of a weft composed of an optical fiber having local light leakage portions distributed in the lengthwise direction, and A warp yarn made of a highly flexible metal ear and the weft yarn are interwoven.

[0009]

In the luminescent decorative fabric constructed as described above, the warp is woven with the weft by the interwoven weave, so that the weft is stably sandwiched from both sides at the intersection with the weft in a substantially straight state. Since the warp is more flexible than the optical fiber, the optical fiber can be clamped more steadily and more stably, and even if the warp is cut, it is easy to burn the cut ends due to its flexibility. Can be connected.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 is an enlarged plan view of a portion of a luminescent decorative fabric according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line II-II of FIG. 1, and FIG. 3 is a sectional view taken along line III-III of FIG. It is a figure.

In FIGS. 1 and 2, 4 is a weft yarn, 5 is a warp yarn, each weft yarn 4 is composed of an optical fiber 1 similar to the conventional one, and its clad 102 is already scratched before weaving by a loom. Leakage portion 1 distributed in the longitudinal direction of the lever
04 are formed. On the other hand, the warp yarns 5 are all made of a soft metal wire 6 which is more flexible than the optical fiber 1. The weft yarn 4 and the warp yarn 5 are interwoven. Since it is virtually impossible to align the optical fiber 1 in a certain direction when viewed in the circumferential direction of its cross section, it is preferable that the light leaking portions 104 are distributed and formed in the circumferential direction. The distribution of the light leakage portions 104 does not need to be regular, and may be a random distribution.

In this way, when the weft yarn 4 and the warp yarn 5 are comb-woven, the warp yarn 5 passes both above and below the weft yarn 4 at the intersection with the weft yarn 4, so that the weft yarn 4 is stably clamped in a substantially straight state. . Since the warp 5 is composed of a soft metal wire 6 which is more flexible than the optical fiber 1, the warp 5 wraps flexibly along the outer peripheral surface of the weft 4 at the intersection with the weft 4 and holds the optical fiber supplely. It will be more stable.

Therefore, there is virtually no possibility that the optical fiber 1 will come out of the woven fabric, and even if the woven fabric is cut, the optical fiber 1 is in a substantially straight state and the flexibility of the metal wire 6 which is the warp 5 is maintained. Since it has a greater flexibility, the weave structure of the optical fiber 1 and the metal wire 6 is broken like the case where the weft yarn 4 as well as the warp yarn 5 is made of the optical fiber 1 despite the elasticity of the optical fiber 1. No, or at least less likely to crumble than such. Further, even if the warp yarn 5 is cut under its tension during the weaving operation, the warp yarn 5 has a large flexibility, so that the cut ends can be easily joined by burning. Further, if the optical fiber 1 which is the weft yarn 4 is cut for some reason, no trouble will occur if the cut weft yarn 4 is removed and the next weft yarn 4 is driven in.

As described above, the present invention adopts the interlace weave, but it is conceivable to use other weave design such as plain weave or twill weave in place of the interwoven weave. However, in these weave designs, the warp 5 passes only one side of the optical fiber 1 which is the weft 4 at the intersection with the weft 4, and the adjacent warp 5 passes the other side of the same optical fiber 1. Since a large bending stress is applied to the optical fiber 1 and the core 101 of the optical fiber 1 is broken, and the transmission of light is interrupted at the broken part of the core 101, other weaving structures such as plain weave and twill weave are quite adopted. Can not. In this respect, if the weave is adopted, the warp 5 sandwiches substantially the same part seen in the longitudinal direction of the weft 4 from the upper and lower sides at the intersection with the weft 4, so that bending stress is not applied to the weft 4. Practically none.

The optical fiber 1 and the metal wire 6 used in the present invention may have various diameters, and the optical fiber 1 has a diameter of 0.5.
The diameter of the metal wire 6 is 0.1.
mm stainless steel wire was used, and both warp and weft were woven with 24 meshes (24 meshes between 25.4 mm, but warp yarns 5 are 24 meshes with two adjacent yarns as one). Was stably held by a stainless steel wire, and the optical fiber 1 did not come out and the woven structure of the cut portion did not collapse.

A rapier loom is used as the loom in the above specific examples. In this case, the end of the weft yarn 4 is grasped by the rapier and pulled from one side in the width direction of the fabric to the other side, but since the flexibility of the optical fiber 1 which is the weft yarn 4 is low, the cut end of the weft yarn 4, that is, When hot air was blown to the gripping part of the rapier to increase the flexibility and then the rapier was used for gripping, the optical fiber 1 could be continuously woven without breaking.

As the metal wire 6, various other wires such as brass wire and copper wire can be used in addition to the stainless steel wire, but since stainless steel is white, it is possible to prevent light from leaking from the optical fiber 1. Not to be a visual obstacle, good rust resistance,
Stainless steel wire is most preferable because of its excellent mechanical strength, especially tensile strength.

If the diameter of the metal wire 6 which is the warp yarn 5 is too small, the tension applied to the metal wire 6 at the time of weaving may cause a wire breakage. Since the holding stability will be reduced, it is necessary to repeat the test in consideration of these factors to select an appropriate diameter, but SUS-304
In case of stainless steel wire of 0.08m
A diameter of about m to 0.2 mm is suitable from the above point.

If the diameter of the optical fiber 1 which is the weft yarn 4 is too small, the amount of light leakage will be small, and if it is too large, the rigidity of the finished product will be large and the flexibility will be lacking. , 0.25 mm ~
0.75 mm is suitable. However, when it is required to have high rigidity or to increase the amount of light leakage in terms of visual effects, a thicker one than 0.75 mm can be used.

The number of meshes is 2 for both the weft yarn 4 and the warp yarn 5.
0-30 are suitable. That is, in the case of the warp 5, if the mesh is smaller than 20 mesh, the holding force of the weft 4 is reduced, and if it is larger than 30 mesh, light leakage of the weft 4 is blocked by the warp 5. Further, in the case of the weft yarn 4, if the mesh size is smaller than 20 mesh, the total amount of light leakage decreases, and if it is larger than 30 mesh, the eyes become fine and the weaving work becomes difficult.

Although the weft yarns 4 are all composed of the optical fibers 1 in the embodiment, some of them may be filaments made of other suitable materials. In addition, the light leakage unit 104
Other than the method of mechanically scratching the clad 102,
It may also be formed by other appropriate means such as locally chemically or thermally scratching, locally bending appropriately, or locally forming a window in the clad when manufacturing an optical fiber.

The light emitting decorative fabric according to the present invention is used for the decoration of side walls and ceilings of rooms, blinds, curtains, dress materials,
Although various kinds of artificial flowers and stage don's books can be considered, an example of use suitable for decorating a side wall of a room will be described with reference to FIG.

FIG. 4 is a partially cutaway perspective view of the wall decoration device according to the above use, 7 is a luminous decorative fabric according to the present invention, and 8 is
Is a long fluorescent lamp arranged along a wall surface (not shown),
Reference numeral 801 is the lamp, 9 is a reflector fixed along both sides of the lamp 801, and the luminous decorative fabric 7 is the weft,
That is, the fluorescent lamp 8 with the optical fiber 1 oriented vertically
Fixed against.

Reference numeral 10 is a hood having a slit-shaped opening 10A in the lower part, and the fluorescent lamp 8 and the reflecting plate 9 are housed therein. Reference numeral 11 is a holding plate for holding the light emitting decorative fabric 7. The holding plate 11 is inserted into the opening 10A and the double-sided adhesive tape 12 is used so that the upper end of the optical fiber 1 faces the lamp 801. Is fixedly held. The woven structure of the luminous decorative fabric 7 is omitted in the drawing.

Therefore, when the fluorescent lamp 8 is turned on, the light of the lamp 801 efficiently enters the light-receiving end of the optical fiber 1 without being randomly scattered by the reflecting plate 9 to the outside from the light leak part of each optical fiber 1. It leaks and exerts a decorative function.

[0026]

As described above, according to the present invention, an optical fiber having a light leakage portion is used as at least a part of the weft, and a metal wire having a greater flexibility than the optical fiber is used as the warp, Due to the extremely simple construction in which the weft yarn and the warp yarn are blind-weaved, it is possible to easily produce a luminous decorative fabric of stable quality, which is free from the optical fiber coming out and the weaving structure of the cutting portion being not broken.
