Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for extracting an imitation fastener by woven an identification yarn as a warp yarn at the time of weaving a cloth tape portion and confirming it visually or by irradiation with excitation light of a specific wavelength. The present invention relates to a slide fastener that can easily detect a very similar counterfeit.

[0002]

2. Description of the Related Art Slide fasteners are mainly made of metal or plastic, and both tapes are made of fabric. Various kinds of sweatshirts, sportswear, blousons, textiles such as winter coats and work clothes, bags and the like are known. It is widely used in bags such as wallets and bedding products such as futons and blanket covers. As for slide fasteners, mainly in Southeast Asia, a large number of counterfeit products that directly copy the shape and brand of commercial distribution products are on the market, and they are sold at lower prices and in large quantities than commercial distribution products. Transactions have declined significantly.

[0003] In addition, as the added value of brand products increases due to long-term use, unscrupulous traders who seek unfair profits by free riding appear, and counterfeit products imitating famous or famous brands are distributed through dark routes. Often. These counterfeit products are manufactured in large quantities in a short period of time using the cheap labor of untapped countries, and are imported and sold at a much lower price than genuine products, thereby causing significant damage to genuine manufacturers. Such counterfeit products are often cut off more than genuine products, and tend to damage the brand image of genuine products.

[0004]

With regard to slide fasteners, imitation products are very similar to genuine products with the advancement of processing technology and textile products, so that not only ordinary consumers but also professional companies can easily consider imitation products as genuine products. There are many cases that cannot be identified. As a result, genuine manufacturers suffer irreparable damage due to the long-term imitation of the genuine product on the same sales channel. In the conventional counterfeiting method, a brand name is stamped on a slider or a metal fitting, or a colored thread is woven into a part of a cloth tape portion. The disadvantages of these methods are that they are very costly and are liable to be imitated by the manufacturer of the imitation, and that they cannot be easily changed.

[0005] On the other hand, early detection of unfair counterfeit goods such as clothing and bags is also necessary to maintain the interests of genuine manufacturers and consumers, and for this reason, brands There is a method of coloring a label with a dye that reacts only to ultraviolet light or infrared light. This method requires special equipment for detecting counterfeit goods, and the cost of distributing the equipment to all traders is very high.

The present invention has been proposed in order to improve the above-mentioned problem relating to the conventional slide fastener, and the identification yarn is woven by irradiating excitation light of a specific wavelength by weaving the identification yarn into a cloth tape portion. It is an object of the present invention to provide a slide fastener that emits light to confirm the presence thereof, detects imitation products or counterfeit products that are very similar to genuine products, and can reliably and easily detect it. Another object of the present invention is to provide a slide fastener which can be caught by visually checking the design and name of the display on the identification thread in the cloth tape portion. Another object of the present invention is to provide a slide fastener capable of not only detecting a counterfeit slide fastener but also detecting a counterfeit product very similar to the product after sewing on the brand product.

[0007]

In order to achieve the above object, a slide fastener to be applied is, like a commercially available product,
There is a mode in which two cloth tape portions each having a tooth row on the opposite side are engaged with each other. In the slide fastener according to the present invention, the identification yarn is woven as a warp when weaving the cloth tape portion, and the identification yarn is present in one or both of the cloth tape portions.

In one example, the slide fastener of the present invention uses a strip obtained by cutting a plastic film into a thread shape as an identification thread. With respect to this film, a fine design or name is printed on the surface of the plastic film with a colored ink containing a fluorescent substance, and the colored ink is made of a clear pigment. Also, a fine design or name may be printed on the front or back surface of the plastic film with an ink containing a usual pigment, and a transparent or translucent ink containing a fluorescent substance may be applied above the design or name. Furthermore, it is also possible to apply a transparent or translucent ink containing a fluorescent substance to the surface of the plastic film and record the fine design and name on the display resin film formed with this ink, while depositing metal on the back of the film It is.

[0009] In another example, the slide fastener of the present invention uses a filament yarn as the identification yarn. With respect to this filament yarn, an inorganic fluorescent substance having a particle size of about 3 μm or less is kneaded into a raw material polymer, and the raw material polymer is melt-spun. Alternatively, a resin solution in which an inorganic fluorescent substance having a particle size of about 3 μm or less is kneaded may be applied to the surface of the mono- or multi-filament yarn.

[0010] In the cloth tape portion of the slide fastener,
It is also possible to perform printing with the engaged tooth surface of the fastener material and the cloth tape portion positioned substantially on the same plane. A print pattern is formed on the surface of the cloth tape portion at a slight vertical interval from the service tooth row except for the location of the service tooth row on the opposing side surface.

[0011] When printing the cloth tape portion of the slide fastener, an elongate underlay having appropriate elasticity is stuck on the printing stand, and then the teeth of the cloth tape portion of the fastener material are engaged and engaged. The tooth row of the fastener material is fitted into the recess of the underlaying base, and the cloth tape portion is removably attached to the underlaying base. By pressing at the time of printing, the surface of the working tooth and the cloth tape portion are positioned on substantially the same plane, whereby the print pattern is applied almost uniformly on the surface of the cloth tape portion.

[0012] The printing of the cloth tape portion is performed in multicolor printing.
After sticking a flexible band-shaped underlay on the printing conveyor in an endless manner, mesh the working teeth of the cloth tape part of the fastener material, and place the engaged working teeth of the fastener material in the recess of the underlay. It is preferable that the cloth tape portion is detachably attached to the underlaying base by being fitted to the base. In this underlay, the surface of the working tooth and the cloth tape portion are positioned on substantially the same plane due to the pressing at the time of printing at each coloring stage by running along with the conveyor, whereby a multicolor print pattern is almost formed on the surface of the cloth tape portion. Apply evenly.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Slide fastener 5 of the present invention
Can be either a mode in which individual metal teeth 6 made of metal or plastic are sandwiched between tape side edges as the service tooth row 1, or a mode in which a series of resin coils called coil fasteners are sewn to the tape side edge. Good. This resin coil is generally made of nylon or polyester. In one or both of the cloth tape portions 2, the identification yarn 14 is woven as a warp yarn at an arbitrary position, and the identification yarn 14 is exposed on the front side or the back side of the cloth tape portion 2 by a weaving method. A part of the pattern may be configured. The number of weaving of the identification yarns 14 is usually one for the fastener 5, but may be plural.

The identification thread 14 may be manufactured from a transparent or translucent film 16 as illustrated in FIG. On the surface of the film 16, a pattern layer 22 is provided by printing many rows of fine designs 18 (FIG. 4) and names 20 (FIG. 5) with colored ink containing an inorganic fluorescent substance. This fluorescent substance emits light only when irradiated with a lamp having excitation light of a specific wavelength, and does not emit light when irradiated with ordinary sunlight or a fluorescent lamp. For printing this ink, fine screen printing or gravure printing is used. Next, the film 16 is cut into a long and narrow thread having a width of about 1 mm by a microslitter or the like, thereby forming many flat tape-shaped identification threads 14.

As shown in FIG. 6, a fine design or name is printed on the surface of the film 26 with an ink containing a normal pigment, and a fluorescent substance is provided on the upper side of the design or name. The fluorescent layer 30 may be formed by applying a transparent or translucent ink containing the phosphor. In this case, as shown in FIG. 7, the pattern layer 28 may be provided on the back surface of the film 26 with an ink containing a usual pigment, while only the fluorescent layer 30 may be formed on the film surface.

To manufacture the identification thread 14, as shown in FIG. 8, a transparent or translucent ink containing a fluorescent substance is applied and dried on the surface of the plastic film 32, and the display resin film 36 is formed with the ink. It may be formed. A metal layer 34 is provided on the rear surface of the film 32 by depositing a metal such as aluminum or silver. The display resin film 36 is appropriately processed so that a fine design or name can be recorded.

The display resin film 36 may be a surface phase hologram, a volume phase hologram, or a phase-separated photopolymer film that reproduces a design or name whose reflected light is fine by diffraction of light. A fine design or name is recorded on the display resin film 36 using the interference. The fluorescent substance added to the display resin film 36 is the same as described above.

In FIG. 9, a fluorescent substance is not added to the display resin film 38 formed on the surface of the film 32, and a transparent or translucent ink containing the fluorescent substance is further applied to the surface of the display resin film to obtain a fluorescent light. The layer 39 is formed. The fluorescent layer 39 may be provided very thin. In this case, providing the metal layer 34 on the back surface of the film 32 is the same as the configuration in FIG.

In the fastener 5, for example, the identification thread 14 in the form of a flat tape is simply woven into the cloth tape portion 2 at the time of weaving, and this weaving does not require any special process or device. Since the identification yarn 14 is sent as a warp yarn during weaving and is not twisted and woven like a weft yarn, the displayed fine design or name can be easily read, and the trader or the consumer can use the fastener 5 with the imitation product. Therefore, it can be easily confirmed that the product to which the fastener is sewn is a genuine product.

It is very difficult to imitate the flat tape-shaped identification thread 14 even if the fastener itself is imitated, because a fine design or name is displayed. Even if the shape of the identification thread 14 is imitated, the identification thread is provided with the pattern layer 22, the fluorescent layer 30, or the display resin films 36 and 38 containing a special fluorescent substance. Simply irradiating the cloth tape section 2 with a lamp that generates excitation light of a specific wavelength can easily detect that the fastener is imitation.

The identification yarn 14 may be a filament yarn 40 as shown in FIG. 10, and when weaving the cloth tape portion 2, the filament yarn 40 kneaded with an inorganic fluorescent substance 42 and spun. Is sent one or more times. In the filament yarn 40, the raw polymer 43 into which the fluorescent substance 42 is kneaded is a known polyester, nylon, acrylic, or the like. The fluorescent substance 42 is the same as described above.

The particle size of the fluorescent substance 42 used is generally about 3
It is not more than μm, and as shown in FIG. 11, a number of extremely thin filament yarns 44 may be twisted and supplied as warp yarns. If the filament yarn 44 cannot be used simply by twisting a large number of filaments, it may be a composite yarn twisted with other ordinary fibers or wound around other fibers. Such a composite yarn may be one or more filament yarns kneaded with a fluorescent substance and composite-spun, or a core-sheath composite yarn or a laminated composite yarn of a polymer kneaded with a fluorescent substance and a normal transparent polymer. is there.

In FIG. 12, a resin liquid in which a fluorescent substance 48 having a particle size of about 3 μm or less is kneaded is applied to a filament yarn 50.
And a thin resin layer 52 is formed on the surface of the filament yarn. As the coating filament yarn 54,
When the resin layer 52 is provided on the surface of the thin filament yarn 50, a large number of twisted identification yarns can be used.
The application of the resin liquid is performed by a dipping method, a spray method such as thermal spraying or electrostatic coating.

The inorganic fluorescent substance used in the present invention is, for example, a phosphor pigment containing a sulfide or an oxide as a main component, and develops blue, green, red, orange, yellow, or the like upon irradiation with specific excitation light. And has little afterglow. This fluorescent substance does not develop color under sunlight or fluorescent light, and it is possible to easily and surely confirm whether or not it is a genuine product if a trader or a consumer irradiates light of a specific wavelength with a small lamp. This fluorescent substance is less toxic than the fluorescent substance of an organic compound, has good weather resistance, printability and other processability, and is generally easy to detect a red color forming body.

The working teeth row 1 is an embodiment in which individual working teeth 6 made of metal or plastic are sandwiched between tape side edges or a series of resin coils sewn to the tape side edges. The upper fastener 7 is attached to one end of the slide fastener 5, and the lower fastener 8 or the opening is attached to the other end.

To manufacture the fastener 5, a fastener material 12 shown in FIG. 2 is used, and the fastener material is drawn out of an automatic fastener manufacturing apparatus (not shown) and wound into a roll. The fastener material 12 has a long shape in which the cloth tape portions 2 and 2 having the engagement teeth 1 on the opposing side surfaces are engaged with each other, and the slider 3, the upper stopper 7 and the lower stopper 8 are not attached. Fastener material 12,
It is applicable from a length of 5 to 10 m for small lots.

The cloth tape portion 2 is generally woven by a known narrow width loom such as a needle loom. In at least one of the cloth tape portions 2, an identification yarn 14 is woven as a warp yarn, and the identification yarn is a warp yarn even if it is a flat tape shape, so that it is not twisted and woven.

In order to manufacture the identification yarn 14, a biaxially stretched transparent polyester film 16 as shown in FIG. 3 is used, and a fine design 18 with a colored ink containing a fluorescent substance is formed on the surface of the film (FIG. 4). And a number of names 20 (FIG. 5) are printed in parallel in a large number of rows to provide a fine design layer 22. It is necessary to use a clear pigment for screen color separation or the like that does not contain a concealing resin and a pigment in the colored ink. The amount of the fluorescent substance added is 20% of the resin dry weight.

n), a red color former (composition: Y ₂ O ₂ S: Eu) and the like are preferable, and a red color former is easily detected. This fluorescent substance emits light having a wavelength of 445 nm for a blue color, a wavelength of 534 nm for a green color, and 624 nm for a red color. The fluorescent substance emits light when irradiated with a lamp having excitation light, has little afterglow, and has a property such that it does not emit light when irradiated with ordinary sunlight or fluorescent light. Generally, the wavelength of the excitation light is 254 nm or 365 nm, which is the wavelength of a commercially available black light.

The film 16 is cut into a thread shape having a width of about 1 mm using a known microslitter or the like to obtain a number of flat tape bodies 23 and 24 illustrated in FIG. 4 and FIG.
The flat tape body 24 is used as the identification thread 14.

In order to manufacture this identification yarn, as shown in FIG. 6, a transparent polyester film 26 is used, and a fine design or name (FIGS. (See FIG. 2) to form a fine pattern layer 28, and apply a transparent or translucent ink containing a fluorescent substance on the upper side of the design or name to form a single fluorescent layer 30. Alternatively, as shown in FIG. 7, a design layer 28 may be provided on the back surface of the film 26 with an ink containing a normal pigment, and the fluorescent layer 30 may be formed on the surface of the film with a fluorescent substance. In this case, the design layer 28 may contain a concealable resin or pigment. The fluorescent substance in the fluorescent layer 30 is the same as described above. The film 26 is formed into a number of flat tapes by a known microslitter or the like, and the flat tapes are used as identification threads.

In order to manufacture this identification yarn, as shown in FIG. 8, a transparent polyester film 32 is used,
A display resin film 36 is formed by depositing an aluminum layer 34 on the back surface of the film and applying a transparent or translucent ink containing a fluorescent substance on the film surface. Fine design and name on display resin film 36 (see FIGS. 4 and 5)
For example, a positive-type, negative-type, or photopolymer-based photopolymer surface phase hologram that can record fine surface irregularities with high accuracy is used. These photopolymers are applied on a thin film of a substrate, and an etching-resistant thin film is formed by irradiation with an excimer laser, an argon laser, or the like. . The obtained substrate is
A large number of designs and names can be duplicated on the display resin film 36 by embossing as a master hologram.

The display resin film 36 may be a volume phase hologram obtained by adding erythrosine or the like as a spectral sensitizer to a photopolymer, and irradiates an object with an argon laser to cause diffracted light transmitted or reflected to interfere with reference light. The fine design and name are recorded on the display resin film 36. The display resin film 36 of the volume phase hologram may be a carbon tetraiodide / polyvinylcarbazole resin or a photopolymerized photopolymer that has been subjected to a photocrosslinking reaction, which may be an argon laser or a He—Ne laser as described above. Can record fine designs and names.

The display resin film 36 may be a phase-separated photopolymer film obtained by photocuring acrylate under special conditions, and the light transmission state changes depending on the angle of incident light. The fluorescent substance added to the display resin film 36 is the same as described above. The film 26 is formed into a number of flat tapes by a known microslitter or the like, and the flat tapes are used as identification threads.

In FIG. 9, the transparent polyester film 3
No fluorescent substance is added to the display resin film 38 formed on the surface of No. 2, and a transparent or translucent ink containing a fluorescent substance is applied to the surface of the display resin film to separately form the fluorescent layer 39. The fluorescent layer 39 is provided very thin with a thickness of several μm,
On the other hand, an aluminum deposition layer 34 is provided on the back surface of the film 32. The display resin film 36 may be processed in the same manner as described above to record a fine design or name.

The identification yarn in FIG. 1 may be a filament yarn 40 as shown in FIG. 10, and the filament yarn is kneaded with about 20% by weight of an inorganic fluorescent substance 42 having a particle size of about 1 to 3 μm. It is produced by melt spinning raw polymer. The raw polymer 43 into which the fluorescent substance 42 is kneaded is, for example, polyester, nylon, or acryl having relatively high transparency. It is preferable that the raw polymer be, for example, polyester. The fluorescent substance 42 may be the same as described above. The filament yarn 40 is supplied as a warp by twisting a single or a plurality thereof.

As shown in FIG. 11, when the fluorescent substance 42 is kneaded into a very thin filament yarn 44, a large number of identification yarns can be twisted and used. Since the thin filament yarns 44 are twisted into a dozen or more yarns to form the identification yarns 46, their appearance and physical properties are almost the same as ordinary polyester yarns, and their tensile strength is also increased. For this reason, if the identification yarn is woven by a high-speed needle loom or the like as a warp yarn, the identification yarn 46 is normally in the cloth tape portion 2 in a normal state.
It is inconspicuous at all, and almost no yarn breakage occurs during weaving.

In FIG. 12, a resin liquid in which an inorganic fluorescent substance 48 having a particle size of about 1 to 3 μm or less is kneaded is applied to the surface of the filament yarn 50, and a thin resin layer 52 is formed on the surface of the filament yarn. Have been. The coated filament yarn 54 can be supplied as a warp yarn. When the resin layer 52 is provided on the surface of the thin filament yarn 50 as the filament yarn 54, a large number of twisted identification yarns can be used. Since the thin filament yarn 54 is twisted into a dozen or more yarns to form an identification yarn, its appearance and physical properties are almost the same as ordinary polyester yarn.

When the filament yarn illustrated in FIGS. 10 to 12 is used as the identification yarn, the cloth tape portions 2 and 2 can be patterned in the state of the fastener material 12 as shown in FIG. For patterning the fastener material 12, a processing device illustrated in FIGS. 14 and 15 is used, and the printing table 55 of the processing device is straight and flat.

In this processing apparatus, the underlay 56
Is composed of two elongated rectangular rails 58, 58 adhered to the printing table 55, and has appropriate elasticity made of rubber, sponge, polyurethane or the like. Parallel rail 58,
58 may be a single rail with a concave cross section. The rails 58, 58 are removably attached to the printing table 55 via a double-sided adhesive tape or an adhesive layer. Similarly, the fastener material 12 is placed on an underlay 56 so as to be lined with the printing stand 55.

At this time, by pressing the squeegee 62, the surface of the engagement tooth 6 and the cloth tape portion 2 are positioned on substantially the same plane, and an appropriate printed pattern 63 such as a character or a pattern is formed on the surface of the cloth tape portion 2 (see FIG. 13). ) Can be formed uniformly. When the printing operation is completed, the screen frame 60 is raised and the ink is returned to the original side edge.

If the print pattern 63 such as a character or a pattern is a multicolor print, the above-described printing process is repeated using a screen frame on which the individual colored inks are placed. The zipper blank 12 can be removed from the underlay 5 when a predetermined printing operation is completed.
6 and cut into a predetermined size, and then the slider 3, the upper stopper 7, the lower stopper 8, and the like as shown in FIG. If the adhesive force of the double-sided adhesive tape or the adhesive on the upper and lower surfaces of the underlaying base 56 is reduced by repeating the printing operation, the underlaying base may be replaced. If screen printing of a normal cloth is performed on the printing stand 55, the underlay 56 may be peeled off from the printing stand 55 and returned to a flat state.

FIG. 16 and FIG. 17 show a continuous processing apparatus for patterning. This processing apparatus includes a pair of pulleys 65 and 6.
It has an endless and wide printing conveyer 66 stretched between five. On the surface of the conveyor 66, belt-shaped underlaying bases 67 are installed endlessly in one row or in parallel, and the number thereof is three in the drawing. Each underlay 67 has flexibility and a concave cross section. The conveyor 66 can run linearly by being supported by an appropriate frame (not shown).

Above the conveyor 66, a number of screen frames 68 to 70 corresponding to the number of colors of the printed pattern are arranged in a vertically movable manner. A pair of guide plates 72, 72 are vertically installed in front of the screen frames 68 to 70, respectively, and the leading ends of the guide plates are close to the fastener material on the underlaying base 67. The distance between the tip portions of the guide plates 72, 72 is substantially equal to the vertical width between the engagement teeth of the fastener material, and each guide plate 72, 72 is, with respect to each screen frame 68 to 70, in the case of multicolor printing. The position of the fastener material is prevented from shifting.

In order to perform printing with this continuous processing apparatus, three fastener materials are respectively adhered on the underlaying base 67 on the left pulley 65 side, and the respective tooth rows are fitted into the concave portions 75. As the conveyor 66 travels in the direction of the arrow in FIG. 16, the colored inks are pushed out below the screen gauze by the screen frames 68 to 70 and adhere to the cloth tape portion. Since the fastener material is positioned each time by the guide plates 72, 72, it does not shift with respect to each of the screen frames 68 to 70. Fastener material is right pulley 6
When it reaches the fifth side, it may be removed from each of the underlaying stands 67.

Visual observation is also possible at this stage. In addition, even if the identification yarn woven into the cloth tape is imitated, the identification yarn has a pattern layer or a fluorescent layer containing a special fluorescent substance, so that a product using the imitation fastener can be easily manufactured. Can be detected.

The slide fastener of the present invention may use a filament yarn kneaded or coated with a fluorescent substance as an identification yarn, and weave the identification yarn when weaving the cloth tape portion. If questions about the authenticity of fasteners and products arise, traders, retailers, and consumers can use a small lamp to irradiate the cloth tape with light of a specific wavelength to easily determine whether the fasteners or products are genuine. And it can be surely confirmed.

The fastener according to the present invention merely weaves the identification yarn as a warp yarn when weaving the cloth tape portion, does not require any special process or device for weaving, and is less expensive to manufacture than a normal fastener. Does not rise much.
ADVANTAGE OF THE INVENTION The fastener of this invention almost eliminates re-imitation by a counterfeit manufacturer by adopting a special fluorescent substance, and can minimize damage.

The slide fastener of the present invention can be printed on a cloth tape portion, and can be used not only for a simple overall pattern such as pattern weaving with a yarn-dyed yarn, but also for a multicolored pattern of rich and complex characters and patterns. Or a special pattern such as a retroreflective layer to which small beads are adhered, or a character or a pattern serving as a trademark, a precautionary statement, or an advertising phrase can be provided. In the fastener of the present invention, since the printed pattern is printed after weaving of the fastener, it can be produced in a much shorter time than the pattern weaving using the yarn-dyed yarn. The fastener of the present invention
Since the printing process of the cloth tape portion is simple, it is possible to produce fasteners that quickly follow the changes in fashion trends, and it is possible to manufacture the fasteners at a relatively low cost without the hassle of designing and selling the fasteners.
