JP4926478B2 - Anti-counterfeit tag clip - Google Patents

Description

  The present invention relates to an anti-counterfeit tag clip that can be used to attach a tag to a product and can confirm an authentic product by irradiation with ultraviolet rays or infrared rays, and further relates to a thread for a tag clip that can verify an authentic product independently.

  When attaching a tag or price tag to a product such as clothing, it is very inefficient to tie the tag to the product with a string. Therefore, as shown in Japanese Patent Publication No. 52-20240, it is common to use an elongated plastic clip. is there. This clip has a shape that connects the enlarged part at the front end and the horizontal bar part at the rear end with a linear part. Load the fixed parts into the mounting device and pull out the clips one by one. Install continuously. This clip prevents the customer from changing tags and price tags, and even an unskilled worker can easily operate the mounting device, so that the price tagging and labeling operations can be accomplished very quickly.

The clip shown in Japanese Patent Publication No. 52-20240 is entirely made of plastic, and when a hard plastic linear portion is driven into a product such as clothing, the clothing is easily damaged, and the clip protrudes from the clothing and may impair the beauty. . In the connector disclosed in Utility Model Registration No. 2538976, in order to improve the point of damage to the product and the appearance, the enlarged portion at the front end and the horizontal bar portion at the rear end are made of plastic, and both are connected by a filament portion. . Since this filament part is flexible, even if it is driven into a product such as clothing, the clothing is not damaged, and there is little discomfort even if it is attached to the clothing. At present, various shapes of clips have been proposed, and the number of clips that can be configured in a ring shape by connecting an enlarged portion at the front end and a horizontal bar portion at the rear end is increasing.

  Although tags and price tags can be quickly attached with the above-mentioned clips, in recent years, there are a large number of counterfeit products on the market that forge a tag displaying a famous brand and improperly use the brand by attaching the tag. As a result, not only does sales of brand products interfere, but there is a frequent occurrence of losing confidence in the quality of brand products. In particular, counterfeit products are manufactured using cheap labor in underdeveloped countries, and are imported and sold at a much lower price than branded products, causing significant damage to branded product manufacturers and distributors. This type of counterfeit product is very similar to a brand product with the advancement of dyeing and sewing techniques for clothing, and it is often difficult for even a specialized trader to distinguish it from the brand product.

  In order to detect a counterfeit product with a counterfeit tag at an early stage, tag dealers have proposed various detection methods such as forming a holography on a tag or printing with a special fluorescent ink. This type of anti-counterfeit tag has a problem that the counterfeit tag is produced after a relatively short period of time, although the manufacturing cost is higher than that of a normal tag, and the effect of authenticity determination is too short. Even if another forgery prevention tag is manufactured and used, a similar forgery tag is produced again in a short period of time, and the endless weasels continue.

  As another problem, if a tag vendor receives the same order from multiple users of the same company for this anti-counterfeit tag, individual tags with different anti-counterfeiting processes must be delivered for each user. In addition, the user must be clearly separated by specifying a pattern such as holography. When such a classification measure is added, if the pattern such as holography is simply subdivided, confusion among users is likely to occur. Therefore, it is necessary to limit the number of individual users to at least a dozen companies. For this reason, tag vendors with more than a hundred users cannot be handled by the forgery prevention tab.

  This inventor examined the said problem regarding the forgery prevention tag with a short effective period from a tag dealer's viewpoint. In this study, instead of taking anti-counterfeiting measures on tags that are relatively easy to forge, if the tag clip for attaching the tag to the product is subjected to anti-counterfeiting processing, the processing costs can be reduced at low cost. We paid attention to the fact that it was easy to understand, and that it was difficult to understand that the measures for preventing forgery were taken. For example, when a fluorescent material is added to the resin of the tag clip and irradiated with ultraviolet rays or infrared rays to develop an arbitrary color, the function of preventing forgery can be provided relatively easily. In particular, when a fluorescent material is added to the yarn body connecting the enlarged portion at the front end and the horizontal bar portion at the rear end made of plastic, the fluorescent material can be added at the time of spinning, so that the processing operation is easy. Since it is also easy to change the fluorescent material added to the above, it is possible to adopt a highly versatile counterfeit prevention measure.

  Accordingly, an object of the present invention is to provide a forgery-preventing tag clip that can easily detect a counterfeit product by irradiation with ultraviolet rays or infrared rays when used when the tag is attached to a genuine product. Another object of the present invention is to provide an anti-counterfeit tag clip that can give individual information to each user in the tag dealer by coloring the thread of the tag clip in multiple colors by irradiation with ultraviolet rays or infrared rays. It is to be. Another object of the present invention is to provide a thread body that can easily detect a counterfeit product by irradiation with ultraviolet rays or infrared rays regardless of the presence or absence of a plastic head and tail.

  The tag clip according to the present invention can be continuously attached to a product by being loaded into an attachment device. The tag clip of the present invention has a plastic head portion, a plastic tail portion, and a thread body connecting the head portion and the tail portion, and the thread body is obtained by twisting a plurality of twisted yarns. And at least one of the twisted yarns is a discriminating yarn. Even if the tag clip is irradiated with visible light, the entire clip is colorless. On the other hand, when irradiated with ultraviolet rays and / or infrared rays, a discrimination thread of the filament is colored in a predetermined color.

  The tag clip according to the present invention has a plastic head portion, a plastic tail portion, and a thread body that connects the head portion and the tail portion, and the thread body has two or more types of discrimination yarns. Each discriminating yarn may be colored by irradiation with ultraviolet rays. Even if this tag clip is irradiated with visible light, the entire clip is colorless. On the other hand, when irradiated with ultraviolet rays and / or infrared rays, the discrimination thread of the filament is colored in a predetermined plurality of colors.

  In the tag clip of the present invention, in the yarn body, the discrimination yarn is formed by twisting ultraviolet and infrared emission fluorescent filaments and ordinary filaments so that the discrimination yarn is colored by irradiation with ultraviolet rays and infrared rays. preferable. This yarn body is formed by twisting together a plurality of colored twisted yarns, and after being twisted, it is dyed as it is or appropriately, and the plastic head and tail are fixed together by molding. .

  In the present invention, a yarn body for tag clip or the like twists three or more discriminating yarns of the same color, and each discriminating yarn is composed of a relatively thick normal support yarn and a relatively thin fluorescent yarn. At this time, the fluorescent yarn is twisted so as to be wound around the support yarn, and the fluorescent yarn is preferably composed of ultraviolet and infrared emitting fluorescent filaments.

  Specifically, the tag clip 1 of the present invention includes one or more discriminating threads 20 (see FIG. 4) that develop color when irradiated with ultraviolet rays and / or infrared rays, as illustrated in FIG. It has the thread body 5 twisted together, and connects the front-end | tip part 2 and the rear-end end part 3 via this thread body. The head portion 2 and the tail portion 3 are made of plastic, and the yarn body 5 is usually integrated at the time of molding. The leading portion 2 and the trailing portion 3 are connected to each other as shown in FIG. 6 to form the thread body in a ring shape, or are used in a string-like manner as shown in FIG.

  The leading portion 2 and the trailing portion 3 are generally made of a polyolefin such as polyethylene or polypropylene, a thermoplastic such as polyamide, polyester, or polyvinyl chloride, and a material having relatively large elongation when the two are connected. Is desirable. The plastic of the head part 2 and the tail part 3 needs to be fused with the thread body 5 at the time of molding, and in the case where the plastics are not mutually fusible, the components can be adjusted appropriately or via an adhesive. Adhere to the thread body 5.

  The yarn body 5 is usually constituted by twisting three or more twisted yarns, and at least one of the twisted yarns is a discrimination yarn 20, and the remaining may be a normal twisted yarn containing no fluorescent substance. The discriminating yarn 20 does not develop color even when irradiated with visible light, remains colorless, and develops a predetermined color when irradiated with ultraviolet rays and / or infrared rays.

  The discrimination yarn 20 may be constituted by twisting only a plurality of fluorescent filaments or twisting the fluorescent filament and a normal filament. Further, a fluorescent yarn 24 (FIG. 4) is formed by twisting only a plurality of fluorescent filaments or the fluorescent filament and a normal filament, and even if a plurality of the fluorescent yarns are further twisted, the fluorescent yarn and the normal yarn are combined. You may comprise by twisting together. Preferably, the discriminating yarn 20 is composed of a relatively thick normal support yarn 23 and a relatively thin fluorescent yarn 24. When the fluorescent yarn 24 is mainly wound around the support yarn 23, the tensile strength is increased. It is easy to check the color development with a relatively small number of fluorescent filaments.

  In the discrimination yarn 20, the fluorescent filament is manufactured by spinning one or two inorganic phosphors having an average particle diameter of 2 to 7 μm in a spinning dope. The resin that is the spinning dope for kneading the phosphor may be a commercially available polyester, polyamide, acrylic, acetate, polyolefin, cellulose acetate, or the like. In general, polyester fibers or nylon fibers are preferably used from the viewpoint of durability and cost. Inorganic phosphors are less toxic and have better dyeability than organic compound phosphors.

Regarding the discriminating yarn 20, the phosphor of an inorganic compound that develops color when irradiated with ultraviolet rays has a chemical composition of Sr ₄ Al ₁₄ O ₂₅ : Eu, Dy (emission peak wavelength 490 nm), Sr ₅ (PO ₄ ) in the case of blue color development. ₃ Cl: Eu (emission peak wavelength 445 nm), ZnS: Ag (emission peak wavelength 450 nm), CaWO ₄ (emission peak wavelength 425 nm), and the like. In the case of green color development, the chemical composition is SrAl ₂ O ₄ : Eu, Dy (emission peak wavelength 520 nm), Zn ₂ GeO ₄ : Mn (emission peak wavelength 534 nm), ZnS: Cu, Al (emission peak wavelength 530 nm), Zn ₂ SiO ₄ : Mn (emission peak wavelength: 525 nm) and the like. In the case of red color development, the chemical composition is Y ₂ O ₂ S: Eu (emission peak wavelength 626 nm), Y ₂ O ₃ : Eu (emission peak wavelength 611 nm), YVO: Eu (emission peak wavelength 619 nm), or the like. In the case of purple color development, the chemical composition is CaAl ₂ O ₄ : Eu, Nd (emission peak wavelength 440 nm). When other phosphors or a mixture of these phosphors are used, about 12 types can be obtained in yellow, light blue, light purple, orange, pink, cream color, etc. About 10 types.

  In the case of the produced filament 5, the fluorescent filament may be kneaded only with a fluorescent material that develops color by ultraviolet irradiation. This fluorescent filament, for example, emits a predetermined fluorescent color when irradiated with a small lamp such as black light 28 (FIG. 5) that emits ultraviolet light having an excitation wavelength of 300 to 400 nm, has little afterglow, and has ordinary visible light. Does not emit light when irradiated.

On the other hand, examples of the inorganic compound phosphor that develops color by infrared irradiation include europium compounds, samarium compounds, zinc sulfide compounds, zinc oxide compounds, and zinc silicate compounds. Specifically, LiAlO ₂ : Fe, (Zn · Cd) S: Cu, YVO ₄ : Nd, or the like can be used to develop red or green color. When the infrared-colored phosphor is a crystal, bright light emission may occur when a specific impurity is added, and it is preferable to add an inorganic activator or sensitizer as such an impurity as appropriate. This phosphor may be surface-treated with an oxide or salt such as chromium or manganese in order to improve stability when added to the resin stock solution.

  The infrared coloring phosphor has an average particle size of 2 to 3 μm and 95% of a particle size of 7 μm or less, and is preferably added in an amount of about 3 to 10% by weight with respect to the spinning dope. At this time, if it is less than 3% by weight, the light emission is weak and difficult to detect, and if it exceeds 10% by weight, it is uneconomical and tends to adversely affect the spinning operation. This phosphor usually emits visible light such as green and red that can be easily distinguished by being excited temporarily by irradiating infrared light having an excitation wavelength of 780 nm to 1 mm, and emits light without visible light or a light source. In addition, there is almost no afterglow, and light emission can be maintained over a long period of time.

  In the discrimination yarn 20, it is preferable to incorporate both ultraviolet and infrared emitting phosphors into the fluorescent filament. In this case, double lock is achieved by the ultraviolet ray irradiation and infrared ray irradiation when the produced yarn body 5 is used. “Double lock” means that it has a double anti-counterfeiting function, and the tag clip filaments are colored by either ultraviolet irradiation or infrared irradiation, so that even if only one is imitated, the anti-counterfeiting function is achieved. Since it can be maintained, the prevention effect is better. In this case, it is very difficult for a manufacturer of counterfeit goods to recognize that anti-counterfeiting by ultraviolet light emitting yarn can be sensed, and that anti-counterfeiting measures are also performed by infrared irradiation. In particular, low-power infrared laser radiation equipment is not as common as the commercially available black light 28 for ultraviolet irradiation, and it is not easy for manufacturers of counterfeit products to purchase infrared laser radiation equipment.

  The double lock may be achieved by twisting the fluorescent filaments that emit infrared rays in addition to the fluorescent filaments that emit ultraviolet rays in the discrimination yarn 20. If desired, a more complicated double lock can be achieved by twisting a plurality of ultraviolet light emitting fluorescent filaments of different colors with respect to the discriminating yarn 20.

  The yarn body 5 can be post-dyed to black or white after twisting three or more twisted yarns or after integrating with the head portion 2 and the tail portion 3. In this post-dyeing, the dye is not dyed with ultraviolet rays or infrared rays, and is usually dyed into a color other than that with ultraviolet rays or infrared rays. However, when the yarn body 5 is post-dyed white, it is difficult to identify the color of the tag clip 1 by irradiation with ultraviolet rays, for example, by bleaching with a fluorescent brightening agent. In this case, the quality of the yarn body before dyeing is checked by ultraviolet irradiation, and the confirmation of the genuine product is determined by infrared irradiation. Even in the case of after-dyeing in black, it is preferable to confirm the authentic product by infrared irradiation.

Even when the plurality of discriminating yarns 20 formed by twisting fluorescent filaments that are clearly different in color and twisted easily are twisted, the yarn body 5 twists only the fluorescent filaments that differ in color or the fluorescent filaments and ordinary filaments. Alternatively, the fluorescent yarn 24 (FIG. 4) may be configured, and the discriminating yarn 20 may be configured by further twisting a plurality of the fluorescent yarns. There are 4 to 12 types of fluorescent filaments with different colors, and they are appropriately selected from these and used for the individual discrimination yarns 20. For example, 10 C ₂ = 45 patterns are obtained when _two of ₁₀ fluorescent filaments are taken out, ₁₀ C ₃ = 120 patterns are obtained when 3 kinds are taken out, and ₁₀ C ₄ = 210 is obtained when four kinds are taken out. This is a pattern, and if it is a medium-sized tag sales business, it is possible to sort each user by a combination of two or more. When the number of distinguishable color fluorescent filaments exceeds 10, the number of user classifications can be increased even with only two combinations.

  This type of thread body can be used not only for connecting the head part 2 and the tail part 3 for tag clips but also for connecting tags and the like as a single thread. In the same manner as described above, this yarn body twists three or more discriminating yarns of the same color, and each discriminating yarn is composed of a relatively thick normal support yarn and a relatively thin fluorescent yarn. Even when the yarn body is used alone, it is vividly colored by irradiation with ultraviolet rays and / or infrared rays, and it can be easily confirmed that the product to which the tag is attached with the yarn body is an authentic product.

  The tag clip 1 is exactly the same as a normal one under visible light. If the user himself / herself or the trader irradiates ultraviolet rays or infrared rays with the black light 28 or the laser emitting device, the filament 5 is colored in a single color or a plurality of colors unique to the user and easily confirms whether or not it is a genuine product. it can. In the tag clip 1, the thread body 5 is the same thickness as a normal product and is colorless, so it is difficult for a counterfeiter to know the presence of the ultraviolet and / or infrared coloring discrimination thread 20 in the thread body 5. If the infrared-colored fluorescent filaments are twisted, it is practically impossible for a counterfeiter to produce similar tag clips.

  The manufacturer of the tag clip 1 manufactures and holds in advance a plurality of types of fluorescent filaments that differ in color by irradiation with ultraviolet rays or infrared rays, and also manufactures ordinary filaments that are substantially the same quality as the fluorescent filaments. preferable. After the possession, if a tag dealer receives a request to give information for preventing counterfeiting to the tag clip 1, a predetermined fluorescent filament is twisted to form a discrimination yarn 20, and the discrimination yarn is further twisted appropriately. Thus, it is possible to manufacture the thread body 5 and specify the thread body 5 for each end user. A large number of the obtained thread bodies 5 are juxtaposed in a predetermined mold, and the assembly 14 of the tag clips 1 can be integrally formed of plastic.

  The tag clip according to the present invention vividly develops color by irradiating the yarn with ultraviolet rays and / or infrared rays by twisting at least one discriminating yarn in the yarn body connecting the plastic head and tail. And it can confirm easily that the goods which attached the tag with this clip are authentic. Since the tag clip of the present invention does not reveal the characteristics of the thread body at all by visual observation and is the same as a normal one under visible light, it is difficult for a manufacturer of imitation products to manufacture the same clip. It is possible to prevent counterfeit products with counterfeit tags from flooding the market.

  The tag clip of the present invention may twist two or more types of discriminating yarns in the yarn body, and in this case, it is possible to more reliably recognize that it is a genuine product by multiple color development of the yarn body. Tag vendors can define different colored tag clips for each user. Tag clips that generate multiple colors can be handled individually for many users, and in addition to confirming genuine products or genuine clothing or garments with tags attached, the manufacturer and date of manufacture of the product Can also be specified.

  In the tag clip of the present invention, when the yarn for discriminating the yarn is colored by irradiation with ultraviolet rays and infrared rays, the yarn may be used as it is, or may be post-dyed to black or white. Is also possible. In the case of post-dying to black or white, the quality of the filaments is checked by ultraviolet irradiation, and the confirmation of the genuine product may be determined by infrared irradiation. The thread body of the present invention can be used as a single thread to bind a tag or the like. Even when used alone, it is possible to easily confirm that a product that is vividly colored by irradiation with ultraviolet rays and / or infrared rays and has a tag attached with the filament is an authentic product.

  Next, the present invention will be described based on examples, but the present invention is not limited to the examples. As shown in FIG. 1, the tag clip 1 has a rectangular rectangular flat head portion 2 and a thin rod-shaped tail portion 3, and a leading end portion 2 and a rear end portion by a thread body 5 having a length of about 12 cm. Is communicated with the last part 3 of. The leading portion 2 is provided with a locking hole 7 penetrating in the lateral direction, and the locking hole has a small diameter portion 8 in the middle of the inside. On the other hand, the tail part 3 is a rod with a round tip having a length of about 10 mm and can be inserted into the locking hole 7. An annular shoulder 12 is formed.

  Since the tag clip 1 is difficult to be loaded in a mounting device (not shown) by itself, the tag clip 1 is used in the form of the assembly 14 as shown in FIGS. The assembly 14 is formed by integral molding with each thread body 5 by injection-molding polypropylene into a mold in which the thread bodies 5 having predetermined dimensions are juxtaposed. In the assembly 14, a large number of tag clips 1 are arranged in parallel, and each of the head portion 2 and the tail portion 3 is connected to orthogonal members 16 and 16 arranged vertically. The elongate orthogonal members 16 and 16 are thin and flexible, and are connected to the head portion 2 or the tail portion 3 via a small diameter connecting portion 18 that can be cut.

  On the other hand, the yarn 5 is used by twisting three discriminating yarns 20 to 22 (FIG. 4) of the same color when irradiated with ultraviolet rays, and the discriminating yarn itself is also a twisted yarn. As shown in the figure, each of the discrimination yarns 20 to 22 includes a relatively thick normal support yarn 23 and a relatively thin fluorescent yarn 24, and the fluorescent yarn 24 is mainly wound around the support yarn 23. . The fineness of the support yarn 23 is about 1000 denier. For example, 126 polyester yarns of 8 denier are twisted. On the other hand, the fineness of the fluorescent yarn 24 is about 100 denier. For example, 20 fluorescent filaments of 5 denier are twisted.

  In the discrimination yarns 20 to 22, the fluorescent filaments constituting the fluorescent yarn 24 are manufactured by kneading two kinds of inorganic phosphors having an average particle diameter of 2 to 7 μm into a polyester resin by melt spinning. The two types of inorganic phosphors are phosphors that develop color when irradiated with ultraviolet rays and phosphors that develop color when irradiated with infrared rays. This fluorescent filament does not emit light when irradiated with ordinary sunlight or fluorescent lamp light, and the filament develops color when irradiated with ultraviolet rays and infrared rays.

In this fluorescent filament, phosphors that develop color when irradiated with ultraviolet rays are blue color formers (chemical composition, Sr ₄ Al ₁₄ O ₂₅ : Eu, Dy), green color formers (chemical composition, SrAl ₂ O ₄ : Eu, Dy), It is a red color former (chemical composition, Y ₂ O ₂ S: Eu, Y ₂ O ₃ : Eu) or a purple color former (chemical composition, CaAl ₂ O ₄ : Eu, Nd). select. Moreover, the fluorescent substance which develops color by infrared irradiation is a red coloring substance (chemical composition, LiAlO ₂ : Fe).

  The yarn body 5 may be used as it is after it has been melt-spun and twisted, or it can be dyed black or white after the discrimination yarns 20 to 22 are twisted together. When the yarn body 5 is post-dyed, confirmation of the genuine product is determined by infrared irradiation.

  As shown in FIG. 5, in order to connect the tag clip 1 to the clothing such as the shirt 27 together with the tag 26, for example, the head row of the assembly 14 in the groove formed in the longitudinal direction of the attachment device (not shown) The tail row is loaded from the rear side of the apparatus, and the assembly 14 is fed forward with the yarn body 5 being bent and held. In the front of the apparatus, the leading portion 2 is received by the support portion of the transfer arm, and the arm is advanced so that the leading portion 2 stands by at the tip portion approaching the axis of the hollow needle. At the entrance of the hollow needle, the tail portion 3 is pushed into the hollow needle by the piston rod, pushed out from the exit of the hollow needle, and fitted into the locking hole 7 of the leading portion 2 waiting just before the exit. And the thread body 5 is formed in a ring shape.

  In the tag clip 1, when the tail portion 3 is inserted into the locking hole 7 of the leading portion 2, the constricted portion 10 of the tail portion 3 is positioned at the small diameter portion 8 of the locking hole 7, and the annular shoulder portion 12 is the small diameter portion. 8, it will not come out of the head part 2 even if the tail part 3 is pulled backward. As a result, the thread body 5 is connected in a ring shape, and the tag 26 and the price tag can be attached to the shirt 27. The tag clip 1 may store a pair of articles such as shoes and gloves together, or may combine a plurality of articles by connecting the tag clips together.

  After the tag clip 1 is attached to the shirt 27 by the attaching device, the generated thread 5 is not colored under visible light or fluorescent light, and is exactly the same as a normal tag clip. When a forgery problem occurs, the user himself / herself or the transaction person irradiates ultraviolet rays with the black light 28 (FIG. 5) and infrared rays with a laser light emitting device (not shown). Since the discrimination yarns 20 to 22 of the thread body 5 are colored in a predetermined color when irradiated with ultraviolet rays and are colored in red when irradiated with infrared rays, it can be easily confirmed that they are genuine products.

  In the tag clip 1, the produced yarn body 5 is double-locked with ultraviolet irradiation and infrared irradiation. The double lock allows the anti-counterfeit function to be maintained even if one of the ultraviolet and infrared coloring is imitated, and has a double anti-counterfeit function. The use of low-power infrared laser radiation equipment for counterfeiting is special compared to the black light 28 irradiated with UV light, and the manufacturer of counterfeit products senses that UV and IR color are double-locked. It is extremely difficult to do.

  The tag clip 30 shown in FIG. 6 has a cylindrical cylindrical head portion 32 and a thin rod-shaped tail portion 33, and the head portion 32 and the tail portion 33 are connected by a thread body 35 having a length of about 22 cm. A cylinder hole 37 is a locking hole in the head part 32, and the cylinder hole has a small diameter part 38 in the middle of the inside. On the other hand, the tail portion 33 is a rod with a thin round tip that can be inserted into the cylindrical hole 37, and a constricted portion 40 is provided at the front portion thereof. The tag clip 30 is loaded into an attachment device (not shown) in the form of an assembly (not shown).

  The filamentous body 35 uses five discriminating yarns 42 to 46 (FIG. 7) that are different in color by ultraviolet irradiation, and each discriminating yarn itself is also a twisted yarn. The discrimination yarns 42 to 46 are each composed of a relatively thick normal support yarn 47 and a relatively thin fluorescent yarn 48, and the fluorescent yarn 48 is mainly wound around the support yarn 47. The fineness of the support yarn 47 is about 800 denier, and, for example, 100 polyester yarns of 8 denier are twisted. On the other hand, the fineness of the fluorescent yarn 48 is about 100 denier, and, for example, 20 5 denier fluorescent filaments are twisted.

  In the discrimination yarns 42 to 46, each fluorescent filament constituting the fluorescent yarn 48 is manufactured by melt spinning by kneading two kinds of inorganic phosphors having an average particle diameter of 2 to 7 μm in a polyester resin. The two types of inorganic phosphors are phosphors that develop color when irradiated with ultraviolet rays and phosphors that develop color when irradiated with infrared rays. This fluorescent filament does not emit light when irradiated with ordinary sunlight or fluorescent lamp light, and the filament develops color when irradiated with ultraviolet rays and infrared rays.

In this fluorescent filament, as a phosphor that develops color by ultraviolet irradiation, a blue color former (chemical composition, Sr ₄ Al ₁₄ O ₂₅ : Eu, Dy), a green color former (chemical composition, SrAl ₂ O ₄ : Eu, Dy), Red chromophore (chemical composition, Y ₂ O ₂ S: Eu, Y ₂ O ₃ : Eu), purple chromophore (chemical composition, CaAl ₂ O ₄ : Eu, Nd), light blue, yellow, pale purple, orange, Ten different color development bodies such as pink and cream colors are used, and a different one is selected for each of the discrimination threads 42 to 46 from these color development bodies. Moreover, the fluorescent substance which develops color by infrared irradiation is a red coloring substance (chemical composition, LiAlO ₂ : Fe).

For the five discriminating threads 42 to 46, five predetermined types are selected from ten types having different colors, and the number of combinations is ₁₀ C ₅ = 252 patterns. In FIG. 7, 10 patterns out of 252 patterns are illustrated. In FIG. 7, a red color discrimination yarn R, a green color discrimination yarn G, an orange color discrimination yarn D, a blue color discrimination yarn B, a purple color discrimination yarn M, a pink color discrimination yarn P, These are a yellow color discrimination yarn Y, a cream color discrimination yarn C, and a sky blue color discrimination yarn S.

  As a result, even if the tag dealer receives similar orders from 252 business users, the tag clip 30 can be delivered clearly sorted for each user, and the tags clearly sorted for each user. The clip 30 can be delivered, and confusion among users can be avoided in advance. Even if the tag distributor is a fairly large company, it is sufficient if 252 companies can be classified.

  The tag clip 30 is mounted on a garment together with the tag by loading the assembly into an attachment device (not shown). The tag clip 30 is merely a normal tag clip in which the thread body 35 does not develop color under visible light, and the discrimination yarns 42 to 46 develop in multiple colors when irradiated with ultraviolet light, and also develop in red when irradiated with infrared light. The tag clip 30 performs double locking of ultraviolet irradiation and infrared irradiation. It is very difficult for a manufacturer of counterfeit goods to sense that the tag clip 30 is double-locked with ultraviolet and infrared colors.

  The tag clip 50 shown in FIG. 8 has a plate-like head portion 52 and a horizontal bar-like tail portion 54 made of polyester, and a leading end portion 52 and a tail end portion of the rear end by a thread body 56 having a length of about 22 cm. Contact 54. The yarn 56 is used by twisting three discriminating yarns of the same color when irradiated with ultraviolet rays. Each discrimination yarn is composed of a relatively thick normal support yarn and a relatively thin fluorescent yarn. The fineness of the support yarn is about 1000 denier, while the fineness of the fluorescent yarn is about 100 denier.

In each discriminating yarn, the fluorescent filament constituting the fluorescent yarn is manufactured by kneading an inorganic phosphor that develops color by ultraviolet irradiation into a polyester resin by melt spinning. In this fluorescent filament, phosphors that develop color when irradiated with ultraviolet rays are blue color formers (chemical composition, Sr ₄ Al ₁₄ O ₂₅ : Eu, Dy), green color formers (chemical composition, SrAl ₂ O ₄ : Eu, Dy), It is a red color former (chemical composition, Y ₂ O ₂ S: Eu, Y ₂ O ₃ : Eu) or a purple color former (chemical composition, CaAl ₂ O ₄ : Eu, Nd). select. The fluorescent filament does not emit light when irradiated with ordinary sunlight or fluorescent lamp light, and develops color when the filament is irradiated with ultraviolet rays.

  The yarn body 56 is used as it is after it is melt-spun and twisted, and is not post-dyed after the three discriminating yarns are twisted together. The tag clip 50 is loaded into an attachment device (not shown) in the form of an assembly, the tag passed through the thread body 56 is held at the head portion 52, and the tail portion 54 is attached to a buttonhole or cloth of clothing.

  The tag clip 50 is mounted on a garment together with the tag by loading the assembly into an attachment device (not shown). The tag clip 50 is merely a normal tag clip without the color of the filament 56 under visible light, and the filament 56 is colored in a predetermined color when irradiated with ultraviolet rays. It is difficult for a manufacturer of counterfeit goods to detect that the tag clip 50 is colored by ultraviolet irradiation.

It is a partial side view which shows an example of the tag clip concerning this invention. FIG. 2 is a partial side view illustrating an assembly of tag clips in FIG. 1.
