Conventionally, as this seed yarn, the one described in Japanese Utility Model Publication No. 58-52300 is known. This involves forming a planar glitter piece having at least the length and width of a fine piece of the diffraction grating film on one side of a transparent synthetic resin film, and then using a transparent adhesive. A sheet with a transparent synthetic resin film formed on its surface is cut into narrow pieces. According to this thread, it has a unique, diamond-like shine on both sides due to individual glitter particles, giving it an elegant and innovative texture that has never been seen before, but the source of the shine is a diffraction grating film. Since the reflection characteristics were only small pieces of glitter, the reflective properties were still not satisfactory. Further, as another conventional example, the one described in Japanese Utility Model Publication No. 58-42461 is known. This is made by cutting a raw material film containing a polyester resin film coated with flaky aluminum paste on one or both sides. In this conventional example as well, the source of the glow was only the scale-like aluminum paste, so it was still unsatisfactory in terms of light reflection characteristics.

した場合に可撓性の面で不十分なものである。 Furthermore, as another conventional example,
The one described in the publication No. 1 is known. This involves forming a transparent film on the outer peripheral surface of a continuous linear object (such as a thread) that has a reflective luster of a metallic color or other color, and then forming a transparent silicone water-repellent film on the transparent film. It is made of embedded glass beads coated with. The water-repellent film, glass beads, and transparent film transmit light, and reflect this light on the outer circumferential surface (reflective glossy surface) of the thread, etc., and the water-repellent film, glass beads, and water-repellent film are formed in the following order: It is designed to emit reflected light. This water-repellent film does not reflect light. The plating layer of the present invention is a reflective material for retroreflecting the light incident on the glass beads (transparent globules), and the water-repellent film and the plating layer are completely different in function and effect. In this conventional example, what corresponds to the plating layer of the present invention is the outer circumferential surface of a thread or the like having a reflective luster, and is far inferior in reflectivity compared to the plating layer. In other words, the outer circumferential surface (reflective glossy surface) of the thread, etc. does not follow the spherical shape of the glass beads, but has a curved surface that is exactly opposite to the curved surface of the glass beads, so that it diffuses the incident light and does not reflect it retroactively. It is. In addition, this conventional example involves processing the peripheral surface of the thread, making it difficult to manufacture, and even if it can be manufactured, the manufacturing efficiency is low, and when twisted, it is insufficient in terms of flexibility. It is something.

ある。 Another embodiment of the first invention shown in FIG. 2 includes a reflective layer 5 formed between the transparent adhesive layer 2 of the base material 1 and aluminum by vacuum deposition on the upper surface of the base material 1.
It has been established. To manufacture the filament shown in FIG. 2, first, a carrier sheet 6 having at least a two-layer structure with one side made of a plastic layer 6a such as a heat-meltable polyethylene film is prepared, and this plastic layer 6a is heated. Then, transparent globules 3 are attached to the layer (see FIG. 3). As shown in FIG. 4, the method of attaching the transparent globules 3 is to pull out the rolled-up carrier sheet 6 with a pull-out roll 7, and then
A heat roll 9 heated to 120°C to 200°C is arranged so as to enter into the tank 8, and the carrier sheet 6 drawn out from the drawing roll 7 is placed inside the tank 8. The transparent globules 3 are passed through hot rolls 9 and deposited in the bath 8 on the plastic layer 6a. The carrier sheet 6 to which the transparent globules 3 are attached is wound up by a winding roll 10. When the carrier sheet 6 is stretched over the thermo roll 9, the thermofusible plastic layer 6a is placed on the outside and the other layer 6b is placed in contact with the roll. Since the heat roll 9 is heated to 120°C to 200°C, the plastic layer 6a melts and becomes sticky, and this stickiness causes the transparent globules in the tank 8 to adhere to the plastic layer 6a. It happens.
By passing between a pair of pressure rolls 11, 11 on the way to the winding roll 10,
It is desirable that the transparent globules attached to the plastic layer 6a are embedded within the plastic layer 6a. The degree of embedding of the transparent small sphere 3 into the plastic layer 6a is preferably about one-third of its diameter. As shown in FIG. 5, on the carrier sheet 6 provided with the transparent globules 3 thus manufactured, a metal such as aluminum is deposited on the exposed portions of the transparent globules 3 by vacuum evaporation.
Approximately 200 g/m 2 of adhesive is applied onto the plating layer 4 formed by means such as vapor deposition, and after heating and drying at a temperature of 120°C for 10 minutes, it is rolled up and left for about 24 hours. Let it harden naturally. The sheet manufactured in this way is referred to as the first sheet 20 (sixth sheet 20).
(see figure). Apart from this first sheet 20, a thickness of 25
A reflective layer 5 is formed on one side of a base material 1 made of a polyester film of about micron size by vapor deposition of a metal such as aluminum by a vacuum evaporation method. This sheet will be referred to as the second sheet 30. And then the first one
On the top surface of the sheet 20, apply approximately 80 g/m 2 of paint adjusted with 100 parts of polyester adhesive, 3 parts of isocyanate crosslinking agent, and 10 parts of solvent.
After drying at 100℃ for 10 minutes, as shown in Figure 8,
The reflective layer surface of the second sheet 30 is laminated using a heated pressure roll 12 . After this pasted sheet was left to harden naturally for about 48 hours, the carrier sheet 6 of the first sheet 20 was peeled off, and the transparent small balls 3
is buried in the adhesive layer 4, and a plating layer 4 is formed in the buried portion of the transparent small sphere 4. What remains after peeling off the carrier sheet 6 is a sheet consisting of the base material 1, adhesive layer 2, transparent globules 3, plating layer 4, and reflective layer 5, and this sheet is cut into narrow widths. As a result, the filaments shown in FIG. 2 are completed. It is preferable to cut finely so that about 80 to 120 filaments can be produced in a width of 1 inch. Then, the cut filament is wound around a cone with the transparent small spheres on the outside. Furthermore, this filament is made into nylon,
Twisted yarn is made by a twisting method such as round twisting, hagoromo twisting, cross twisting, Chiyoda twisting, etc. with filaments such as human silk or polyester. One layer 6b constituting the carrier sheet 6 is made of a polyester film with a thickness of about 75 microns, but it may be made of other plastic material with a smooth adhesive surface to the plastic layer 6a. It may be smooth paper. In this way, a carrier sheet 6 having at least a two-layer structure in which a thermofusible plastic layer 6a is laminated and integrated on the surface of a layer 6b made of a plastic material, paper, etc. with a smooth surface is used, and the plastic layer 6a of the carrier sheet 6 is Temporarily adhering the transparent spheres 3 to the layer 6b means that the ridges of the transparent spheres 3 will come into contact with the smooth surface of the layer 6b and become smooth, so that the carrier sheet 6 will be peeled off and the transparent spheres 3 will be glued together. After transferring the layer 2, the exposed upper ends of the transparent globules 3 can have a uniform height. Furthermore, it is extremely convenient to form the plating layer 4 on the necessary portions of the transparent small spheres 3.

…20 parts by weight Methyl ethyl ketone …106.5 parts by weight Epoxy resin …0.75 parts by weight Dimethyl formamide …75 parts by weight Pearlescent pigment platelets …100 parts by weight Basic lead carbonate or the like is used as the pearlescent pigment platelets (reflective material 13). The adhesive has a size of about 8 to 25 microns and a thickness of about 40 to 200 microns. The adhesive mixed with the pearlescent pigment platelets is applied so as to cover the transparent small spheres 3. The coating thickness of this pearlescent pigment platelet-incorporated adhesive is approximately 150 microns wet thickness. Methyl ethyl ketone and methyl formamide are solvents in the composition, and during volatilization of these solvents, the characteristics of the pearlescent pigment platelets are that they are arranged in multiple layers surrounding the transparent globules. When the pearlescent pigment platelets are arranged in multiple layers so as to surround the buried portion of the transparent small sphere 3, the light rays that are refracted and incident on the transparent small sphere 3 are reflected by the pearlescent pigment platelets. When it hits the plate, a portion is reflected, and the rest is transmitted, and when it hits the next pearlescent pigment platelet, similarly, a portion is reflected and the rest is transmitted. The light reflected by the pearlescent pigment platelets in each layer is refracted and passed through the transparent small spheres 3 and is retroreflected. Due to the light properties of these pearlescent pigment platelets, which partially reflect and partially transmit, a multilayered light reflection effect is achieved.
The reason why the pearlescent pigment platelets surround the buried part of the transparent small sphere 3 and are arranged in multiple layers is that when applying the adhesive, the coating surface and the brush, etc. Parallel viscous flow occurs due to shear motion, etc., and due to this viscous flow, the pearlescent pigment platelets in the adhesive try to align in parallel, but due to the presence of the transparent globules 3, the transparent globules 3 are present in the adhesive. A viscous flow along the sphere 3 occurs, which disturbs the parallel alignment of the pearlescent pigment platelets and results in an alignment along the spherical surface of the transparent globules 3. To elaborate on the above-mentioned retroreflection effect, when the pearlescent pigment platelets are arranged around the buried part of the transparent sphere 3, the light L 1 is incident on the transparent sphere 3 and refracted, and the pearlescent pigment platelets are arranged around the buried part of the transparent sphere 3. The light hits the pigment platelets and is reflected in multiple layers, is refracted by the transparent small sphere 3, and is reflected toward the light source as light L2 (see Figure 11). In other words, retroreflection is performed which returns to the direction of the light source. When the transparent small sphere 3 is not buried, the pearlescent pigment platelets are arranged in parallel, and the light L hitting them is as shown in Fig. 12a.
As shown in Figure 12b, multiple reflections occur, resulting in strong reflections and pearlescent luster, but if metal powder is mixed instead of pearlescent pigment platelets, it can be seen in Figure 12b.
As shown in the figure, the light L is scattered. This has long been known as a property of pearlescent pigment platelets. Furthermore, as shown in FIG. 12a, the pearlescent pigment platelets have extremely low hiding power, and the light L is repeatedly reflected while passing through several layers of the pearlescent pigment platelets. This property of extremely low hiding power means that while metal powders have a blackish tinge, making it difficult to mix them into beautiful colors, pearl pigments can be mixed freely without creating a blackish tint. It is guaranteed. In this way, the transparent beads 3 are attached to the carrier sheet 6, and the transparent beads 3 are coated with an adhesive mixed with a reflective material 13 made of pearlescent pigment platelets, as shown in FIG. A similar base material 1 is bonded under pressure. Next, by peeling off the carrier sheet 6, a sheet having a structure as shown in FIG. 10 is obtained. Cut this sheet into thin strips, and add 1 strip of this cut stripe.
By twisting one or more fibers with a filament such as nylon, a light-reflecting twisted yarn can be obtained.

It is also possible to color this reflective layer 5 with a desired color. Furthermore, a dye of a desired color may be mixed into the adhesive layer 2 mixed with the reflective material 13 consisting of the pearlescent pigment platelets.

By dropping transparent globules 3 onto this adhesive layer 2 before the adhesive of this adhesive layer 2 has dried, i.e. while this adhesive layer 2 is still wet,
It is also possible to form a multiple multilayer reflective layer 14 by embedding the transparent globules 3 and surrounding the embedded part with pearlescent pigment platelets and arranging them in multiple layers.

As explained above, according to the present invention, a transparent adhesive layer is formed on a base material, and transparent small spheres having a refractive index of at least 1.9 or more are attached to the adhesive layer by at least three times the diameter of the transparent small spheres. 1 or more are buried and fixed,
The buried part of the transparent globule is plated with a highly reflective substance by means such as vacuum deposition to form a plating layer that retroreflects light incident on the surface of the transparent globule, and the base material, adhesive A sheet consisting of a layer, a transparent sphere, and a plating layer is cut into thin strips, and one or more of these cut filaments are twisted with a filament such as nylon. The light hits the plating layer, is reflected, and returns to the light source through the transparent sphere. Therefore, the light reflecting performance of the twisted yarn is higher than that of any conventional twisted yarn that emits a glow, and if this twisted yarn is used in obi fabrics or other clothing, it is possible to create novel clothing that has never existed before. In addition, since the filament of nylon or the like is twisted with a filament having transparent spherules on one side, a reflective surface exists over the entire circumference of the twisted yarn, and the transparent spherules are intertwined with the filament, which improves strength and flexibility. It is possible to obtain a twisted yarn with excellent flexibility.

が良くなるものである。 In the case where a reflective layer formed by vacuum-depositing aluminum on the top surface of the base material is provided between the base material and the transparent adhesive layer, light rays that do not enter the transparent globules also pass through the adhesive layer. Since the light passes through the reflective layer, passes through the adhesive layer again and is reflected, the presence of the plating layer and the reflective layer further improves the reflection efficiency.

The formed transparent globules surrounded by a plating layer are covered with a transparent adhesive layer, the carrier sheet and the adhesive layer are peeled off, the transparent globules are buried in the adhesive layer, and the plating layer is applied to the buried part. In the formed product, the heights of the upper ends of the transparent globules exposed from the adhesive layer are uniform, and the formation of the plating layer becomes easy and reliable.
Furthermore, since the plating layer and the reflective layer can be colored with a desired color, it is also possible to produce twisted yarns with higher brightness at low cost and in large quantities compared to conventional gold threads, silver threads, and other colored threads.

As a characteristic of the above, the sheet consisting of the base material, adhesive layer, transparent globules, and multi-layer multi-reflective layer is arranged in multiple layers to form a multi-layer multi-reflective layer, and the sheet consisting of the base material, adhesive layer, transparent globules, and multi-layer multi-reflective layer is cut into narrow widths, and the cut filaments are cut into 1
Since the book or two or more books are twisted with a filament such as nylon, the following remarkable effects are achieved. In other words, due to the presence of multiple reflective layers, the light incident on the transparent sphere is refracted and hits the pearlescent pigment platelets one after another, and a portion of the light is reflected at each pearlescent pigment platelet. The light passes through the transparent sphere again and returns to the light source, resulting in extremely excellent reflection characteristics. Pearlescent pigment platelets have extremely low hiding power, so they can be toned into beautiful colors without becoming dark like metal powder.

It exhibits even more reflective properties. One side of a carrier sheet having at least a two-layer structure is made of a plastic layer such as a thermofusible polyethylene film, and this plastic layer is heated to reflect the exposed transparent globules attached to the layer. In cases where the transparent globules are coated with an adhesive layer containing a mixture of materials, the carrier sheet and the adhesive layer are peeled off, and the transparent globules are buried in the adhesive layer, the heights of the transparent globules exposed from the adhesive layer are uniform. It will be done. Furthermore, since the reflective layer can be colored in a desired color, twisted yarns in a desired color can be produced in large quantities at low cost.
