JP4926439B2 - Manufacturing method of anti-counterfeit woven label and anti-counterfeit woven / knitted fabric - Google Patents

Description

  The present invention relates to a woven label and a fastener capable of confirming genuine products by irradiation of ultraviolet rays and infrared rays and capable of providing information for each user, and further relates to a method for optionally manufacturing a forgery-preventing woven or knitted fabric including the woven label.

  In recent years, popularity has been concentrated on products of famous brands, and a large number of counterfeit products illegally using the brands are on the market. 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 in large quantities using cheap labor in underdeveloped countries, and 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 brand products with the advancement of dyeing and sewing techniques relating to clothing, and it is often difficult for specialist traders to distinguish them from brand products. When it is difficult to identify, counterfeit goods exist for a long time on the same sales route as brand goods, and the manufacturers and distributors of brand goods suffer a great deal of damage.

Various detection methods have been proposed at present in order to detect illegally forged goods at an early stage. As an example, European Patent Application Publication No. 0328320, JP-A-6-306727, and JP-A-7-92911 manufacture a woven label in which a luminescent yarn mixed with an inorganic or organic phosphor is woven together with a normal yarn. . By sewing this woven label on clothing, when the label is irradiated with ultraviolet rays when necessary, it can be identified whether or not it is a counterfeit by the presence or absence of the luminescent yarn. Japanese Patent Application Laid-Open No. 7-92911 develops various colors by combining red, blue and green phosphors or these phosphors, and weaves them in the entire woven label or fabric. Japanese Patent No. 2986714 in which the inventor is an employee of this applicant also uses an ultraviolet phosphor that emits red, blue or green light.

  Such anti-counterfeit woven labels are already widely recognized in the textile industry. This woven label has the effect of authenticity determination even for a relatively short period until it is known that a specific fluorescent yarn has been woven. For this type of woven label, if the label manufacturer receives a similar order from a sewing maker or the like as a plurality of users, the meaning of preventing forgery is lost unless a woven label of a different color is delivered for each user. For this reason, the label manufacturer separates the users by specifying different intervals between the fluorescent yarns when weaving a different number of fluorescent yarns for each user's woven label and incorporating a plurality of fluorescent yarns. Even if such a separation measure is added, if the number and interval of the fluorescent yarns are excessively subdivided, the users will be confused. Therefore, the number of users that can be handled is only a few dozen at most.

  A woven label is a decorative trademark label that is sewn mainly on the back of clothing, bags, clothing accessories, blankets, etc. The label has a complex and beautiful pattern using a loom equipped with a jacquard machine. Weave out. When fluorescent yarn is woven into the central part where there are many floating yarns of colored yarn that displays designs and characters, the fluorescent yarn sinks, making it difficult to discriminate by UV irradiation, and the design tends to be uncomfortable. There is no choice but to weave around the label area. If the weaving of the fluorescent yarn is limited to the peripheral portion of the label, the number of users that can be handled is reduced to about 10 companies, and the present applicant with more than 100 companies cannot respond at all.

  Yet another problem is that trademark woven labels have different dimensions and planar shapes depending on the type and quality of clothing even for the same user, and labels with different numbers of warps and wefts, width, length and density. There are many. In order to always weave the same number of fluorescent yarns at the same warp and weft positions and intervals for the same user's large and small woven labels, in the case of warp, the number of fluorescent yarns and the weaving positions for each of the many woven labels in warping It is necessary to define precisely, and this is still a difficult task even today managed by a computer.

  The present inventor examined the above-mentioned problems related to the anti-counterfeit woven label from the viewpoint of the label manufacturer. In this study, we focused on the fact that if a specific yarn, which is a fluorescent yarn, can be colored in a plurality of different colors, a large number of users can be identified even if only one is woven into the woven label. If the specific thread is one of weft or warp in the woven label, even if the dimensions of the woven label are various in the user, the weaving position is arbitrary around the label, and a highly versatile anti-counterfeit label is produced. It becomes possible to do.

  Accordingly, an object of the present invention is to provide a forgery-preventing woven label and fastener that can easily detect similar products by irradiation with ultraviolet rays or infrared rays. Another object of the present invention is to provide a forgery-preventing woven label and fastener having a specific yarn that develops into a plurality of colors when irradiated with ultraviolet rays or infrared rays, regardless of the size of the woven body. Another object of the present invention is to provide a method for producing a forgery-proof woven or knitted fabric that can be easily knitted by a label manufacturer and can be delivered inexpensively and quickly.

  The woven label according to the present invention can give individual information to each user by coloring the specific yarn into a plurality of colors. The woven label of the present invention uses a specific yarn obtained by twisting at least two kinds of fluorescent filaments having different colors and a normal filament that is the same as the fluorescent filament and does not contain a fluorescent substance. By weaving this specific yarn as a weft or warp when weaving, the whole is colorless even when irradiated with visible light. On the other hand, when irradiated with ultraviolet rays and / or infrared rays, the specific yarn, which is a woven twisted yarn, has a plurality of colors. Color develops.

  The fastener according to the present invention can give individual information for each user by coloring a specific thread into a plurality of colors. The fastener of the present invention uses a specific yarn obtained by twisting at least two types of fluorescent filaments having different colors and a normal filament that is the same as the fluorescent filament and does not contain a fluorescent substance. By weaving this specific yarn into the tape part of the slide fastener or the hook-and-loop fastener main body during weaving, the whole is colorless even when irradiated with visible light, whereas it is a twisted yarn woven when irradiated with ultraviolet rays and / or infrared rays. Specific thread develops in multiple colors.

  In the woven label or fastener described above, it is preferable to achieve double lock by irradiating ultraviolet rays and infrared rays by twisting at least one kind of ultraviolet emitting fluorescent filament and infrared emitting fluorescent filament in the specific yarn.

  In the method for producing a woven or knitted fabric according to the present invention, a large number of fluorescent filaments having different colors and normal filaments that are the same as the fluorescent filament and do not contain a fluorescent material are held, and information on preventing forgery is imparted to the woven or knitted fabric. When a request is received from a user, at least two types of differently colored fluorescent filaments specified by the user are selected. The yarn is twisted together with a plurality of normal filaments, and then the knitted or knitted fabric is knitted or knitted while weaving the specific yarn at a predetermined location on a loom or knitting machine.

  In the method for producing a woven or knitted fabric of the present invention, the fluorescent filaments are colored in red, blue, green, yellow and / or other colors, respectively, by irradiation with ultraviolet rays. Further, the fluorescent filaments may be colored red, green and / or other colors by irradiation with infrared rays. The fluorescent filament and the normal filament are preferably made of unbleached polyester fiber or nylon fiber.

  To describe the present invention in detail, in order to carry out the method of the present invention, a label manufacturer pre-manufactures a plurality of fluorescent filaments 1 (FIG. 1) that differ in color by irradiation with ultraviolet rays or infrared rays, and further the fluorescent filaments. It is necessary to manufacture and hold a normal filament 2 (FIG. 2) that is substantially the same as the above and does not contain a fluorescent material. After the completion of possession, if a request is received from a user to give information on preventing forgery to a predetermined knitted or knitted fabric, two or more types of fluorescent filaments 1 having different colors are selected, and the user is specified to identify a plurality of these. A specific yarn 3 (FIG. 3) for preventing forgery is prepared by twisting together with the filament 2.

  As illustrated in FIG. 1, the fluorescent filament 1 is manufactured by spinning an inorganic phosphor 5 having a particle size of about 4 to 7 μm in a spinning solution. The resin 4 that is a spinning solution into which the phosphor 5 is kneaded may be a commercially available polyester, polyamide, acrylic, acetate, polyolefin, cellulose acetate, or the like. In general, polyester fibers are preferably used from the viewpoint of durability and cost. On the other hand, as shown in FIG. 2, the normal filament 2 is usually made of only the resin 4 and has the same or similar material and diameter as the fluorescent filament 1 and does not include the fluorescent material 5 and therefore irradiates ultraviolet rays or infrared rays. Even if it does not color. The filaments 1 and 2 can be pre-dyed or post-dyed to a predetermined color except for some dyes and pigments.

If the phosphor 5 of an inorganic compound kneaded into the fluorescent filament 1 is colored by ultraviolet irradiation, for example, in the case of blue color development, the chemical composition is Sr ₄ Al ₁₄ O ₂₅ : Eu, Dy (emission peak wavelength 490 nm), Sr ₅ (PO ₄ ) 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 plurality of these phosphors are mixed, it is possible to obtain about 12 colors of fluorescent filaments 1 that can be distinguished by yellow, light blue, light purple, orange, pink, cream color, etc. . For example, the fluorescent filament 1 emits a predetermined fluorescent color when irradiated with a small lamp such as a black light 7 (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.

The phosphor of the inorganic compound may be a fluorescent filament 8 (FIG. 3) that develops color by infrared irradiation. In this case, the phosphor is a europium compound, a samarium compound, a zinc sulfide compound, a zinc oxide compound, Examples include 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. 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. The fluorescent filament 8 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.

  The infrared colored fluorescent filament 8 may be used together with the ultraviolet colored fluorescent filament 1 in the specific yarn 3 (FIG. 3), and is not used alone. In the case of an infrared-colored phosphor, if it 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. 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.

  In a normal product mode, in addition to at least one type of ultraviolet light emitting fluorescent filament 1, it is preferable that an infrared coloring fluorescent filament 8 is always twisted into the specific yarn 3 to perform double locking of ultraviolet irradiation and infrared irradiation. In this case, it is very difficult for the counterfeiter to recognize that the counterfeit prevention by the ultraviolet light emitting yarn is taken, and that the counterfeit prevention measure is further performed by infrared irradiation. In particular, low-power infrared laser radiation equipment is not as common as commercially available black light 7 for ultraviolet irradiation, and it is not easy for counterfeiters to purchase infrared laser radiation equipment.

Fluorescent filaments 1 and 8 are selected from two or more types, and as shown in FIG. 3, a plurality of normal filaments 2 are twisted together to obtain a specific yarn 3 having the same thickness as other warp and weft yarns in a woven or knitted fabric. . For example, when 10 kinds of fluorescent filaments 1 and 8 having different colors are held, a combination obtained by removing two of them is ₁₀ C ₂ = 45 patterns, and a combination obtained by removing 3 kinds is ₁₀ C ₃ = 120 patterns. The combination obtained by extracting the four types is ₁₀ C ₄ = 210 patterns. When all of the combinations obtained by extracting the ten types are added, (45 + 120 + 210 + 252 + 210 + 120 + 45 + 1) = 1003 patterns is sufficiently practical. If ten types having different colors are held, the 627 pattern can be obtained by always twisting the infrared-colored fluorescent filament 8 or by twisting up to five types.

  Referring to FIGS. 5 and 6, the specific yarn 3 is woven into the woven label 10 (FIG. 5), the fastener 12 (FIG. 6), or the like. In the specific yarn 3, two or more types of fluorescent filaments 1 and 8 having different colors are twisted, and the label usage destination can be identified by the specific color and the number of colors. On the other hand, since the woven label 10 shown in FIG. 4 is under visible light, the fluorescent filaments 1 and 8 do not develop color, and the specific yarn 3 is buried in other weft yarns or warp yarns. Although the fastener shown in FIG. 6 is the slide fastener 12, it can be easily applied to a surface fastener woven in a tape shape.

  As illustrated in FIG. 7, the woven label tape 14 is usually manufactured by heat-cutting a wide woven fabric 11 (FIG. 8) in which the specific yarn 3 is woven as a normal weft or warp into a plurality of strips. If desired, the tapes 14 can be woven one by one using a narrow loom such as a needle loom, in which case heat cutting is unnecessary. For example, in FIG. 7, the specific yarn 3 is woven into the tape 14 as a weft, and in FIG. 6, the specific yarn 3 is woven into the tape portion 16 of the fastener 12 as a warp.

  FIG. 8 schematically shows the entire side surface of the loom 18 that weaves the tape 14. For example, a warp beam 19 is rotatably installed behind a high-speed wide loom 18 that is a rapier loom. In the loom 18, a normal warp yarn 20 is connected from the warp beam 19 to a front weave 28 through a back roller 22, a plurality of healds 24 and a rapier 26. The warp yarns 20 are divided into upper and lower portions by the twill rods 30 arranged in the orthogonal direction, and then pass through the holes of the heald 24 for each warp yarn. Each heald moves up and down to open the warp yarn group up and down, let the weft pass through the rapier 26 or the shuttle, and pass the specific yarn 3 for each weaving pattern. The weft yarn and the specific yarn 3 are struck to the pre-weaving 28 by a sley (not shown) and are made orthogonal to the warp yarn 20 to obtain the wide woven fabric 11.

  The woven wide fabric 11 reaches the clothing roll 34 from the pre-weaving 28 via the guide roller 32 and passes through the pair of press rolls 36 and 36. In the loom 18, a large number of hot knives 38 are obliquely attached in front of or behind the press rolls 36, 36, and the wide woven fabric 11 passing is heated and cut to a label width W (FIG. 7). The obtained multiple woven labels 10 are wound around a cross beam 52 through an ironing roll 40 in order to stabilize the shape thereof. In addition, after the wide fabric is wound on the cross reel 42, it can be heat-cut into a large number of woven labels 10 by another heat cutting machine.

  As illustrated in FIG. 7, when weaving the wide woven fabric 11, the specific yarn 3 is woven into each woven pattern, and a large number of woven labels 10 (FIG. 4) are manufactured by heat cutting the woven fabric. Whatever the size of the woven label 10, one or more specific yarns 3 may be woven into each woven label 10. As a result, even if the size of the woven label 10 required by the sewing manufacturer that is the user is various, the label manufacturer can easily perform the forgery prevention process unique to the manufacturer.

  The woven label 10 and fastener 12 obtained by the method of the present invention are the same as usual under visible light. If the user himself / herself or the trader irradiates ultraviolet rays or infrared rays with the black light 7 or the like, the specific yarn 3 is colored in a plurality of colors unique to the user, and it can be easily confirmed whether or not the product is a genuine product. In the woven label 10 and the fastener 12, the specific yarn 3 has the same diameter as the surrounding normal yarn and is colorless, so it is difficult for a counterfeiter to know that the specific yarn is woven, and the presence of the specific yarn can be confirmed. However, it is impossible to recognize a color pattern formed by a plurality of luminescent yarns. For this reason, it is almost impossible for a counterfeiter to weave into the woven label 10. The inorganic phosphor contained in the ultraviolet fluorescent filament 1 and the infrared fluorescent filament 8 is less toxic than the organic compound phosphor, and has good weather resistance and printability.

  In the woven label and fastener according to the present invention, a plurality of types of fluorescent filaments having different colors and a normal filament not containing a fluorescent substance are appropriately selected, and a specific yarn is produced by twisting the selected filament. It is only necessary to weave when weaving. Multiple types of fluorescent filaments and normal filaments need to be spun and held in advance, and because of the very fine fibers, the storage space may be narrow at the time of holding, and specific filaments dedicated to users are twisted from these filaments It is also an easy task.

  The woven label and fastener of the present invention are exactly the same as usual under visible light, even if the specific yarn is woven as warp or weft. If there is any doubt about the authenticity of the product, it is possible to easily identify whether or not the product is a genuine product by irradiating ultraviolet rays or infrared rays to identify the specific yarn and using a plurality of colors of the specific yarn. In the woven label and the fastener, the presence of the specific yarn is unknown only by visual observation, and it is practically difficult for a manufacturer of similar products to manufacture the same label or fastener. As a result, even if the similar product is so similar that the garment or garment with the woven label or fastener sewn cannot be distinguished from the appearance even by a specialized trader, the similar product is determined based on the woven label or fastener. It can be detected early and reliably.

  The manufacturing method of the woven or knitted fabric according to the present invention can be manufactured in the same manner as a normal woven or knitted fabric by weaving the specific yarn together with the weft or warp during the knitting. Therefore, even if the dimensions of the woven label and fastener required by the user are various, a manufacturer of the woven label or the like can easily cope with it by simply twisting and weaving a specific thread dedicated to the user. Manufacturers of woven labels, etc. can easily provide anti-counterfeit woven labels or fasteners dedicated to each user, even if there are more than 100 users requesting woven labels and fasteners of various sizes. Management and storage are almost the same as general products.

  Next, the present invention will be described based on examples, but the present invention is not limited to the examples. Each of the fluorescent filaments 1 and 8 was melt-spun by kneading an inorganic phosphor having a particle size of 4 to 7 μm into the polyester resin 4. On the other hand, the normal filament 2 was obtained by melt spinning the polyester resin 4 as a spinning solution. A total of 12 filaments were used, and when this was twisted, the fineness of the specific yarn 3 was 7.5 denier.

As for the fluorescent filament 1, nine types having different color developments include 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), and a red color development. Body (chemical composition, Y ₂ O ₂ S: Eu, Y ₂ O ₃ : Eu), purple color former (chemical composition, CaAl ₂ O ₄ : Eu, Nd), light blue, yellow, light purple, orange, pink A cream colored chromophore was used. These phosphors emit light in a predetermined color when irradiated with ultraviolet rays, and do not emit light when irradiated with ordinary sunlight or fluorescent light. Ten types of fluorescent filaments 1 were produced and held by kneading each phosphor.

On the other hand, for the fluorescent filament 8, a red color former (chemical composition, LiAlO ₂ : Fe) was used. This phosphor emits red light when irradiated with infrared rays, and does not emit light when irradiated with ordinary sunlight or fluorescent light. This phosphor is kneaded and the fluorescent filament 8 is always twisted as shown in FIG.

In the twisting process, there are 10 types of fluorescent filaments 1 of different colors, and an appropriate one is selected, and one fluorescent filament 8 and an appropriate number of normal filaments 2 are added to twist a total of 12 yarns. The specific yarn 3 is manufactured. FIG. 3 shows an example in which four types of fluorescent filaments 1 are selected, and one fluorescent filament 8 and seven normal filaments 2 are added, and a total of 12 yarns are twisted. There are ₁₀ C ₄ = 210 patterns for combinations that extract 4 types from 10 types, of which 10 patterns are shown. In FIG. 3, the fluorescent filament 1R that develops red color with ultraviolet rays, the fluorescent filament 1G that develops green color, the fluorescent filament 1D that develops orange color, the fluorescent filament 1B that develops blue color, the fluorescent filament 1M that develops purple color, the fluorescent filament 1P that develops pink color, A yellow colored fluorescent filament 1Y, a cream colored fluorescent filament 1C, and a blue colored fluorescent filament 1S.

  In the weaving process, in the rapier loom 18 shown in FIG. 8, the warp yarn 20 drawn backward from the warp beam 19 performs a warp yarn opening motion using a jacquard (not shown), and the path generated by the opening motion. A wide woven fabric 11 was woven by passing a colorless polyester yarn through the rapier 26 as a weft and passing the specific yarn 3 for each weaving pattern. In the rapier loom 18, a large number of hot knives 38 are attached to the rear of the press rolls 36, 36, and the wide woven fabric 11 is band-shaped heat cut, so that a large number of woven label tapes 14 can be produced simultaneously from the wide woven fabric, Each of these was wound on a cross reel 42.

  As shown in FIG. 8, the tape 14 is cut along the straight line 54 at the cutter part of the cut and hold machine, and then sent to the holder part of the cut and hold machine, held in the middle, and pressed to display each display mark. The woven label 10 (FIG. 4) cut into pieces was formed. The woven label 10 is usually sewn on the back side of clothing.

  The woven label 10 is merely a normal label after the sewing, under the visible light, the fluorescent filaments 1 and 8 of the specific thread 3 are not colored. If the user himself / herself or the trader irradiates ultraviolet rays or infrared rays with the black light 7, the specific yarn 3 is colored in a plurality of colors unique to the user, and it can be easily confirmed whether or not the product is a genuine product. For example, in FIG. 3 (1), the specific yarn 3 develops red, blue, green, and purple when irradiated with ultraviolet rays, and develops red when irradiated with infrared rays. In FIG. 3 (2), red, yellow, green and purple are colored by ultraviolet irradiation, and red is colored by infrared irradiation.

  In the woven label 10, double-locking of ultraviolet irradiation and infrared irradiation is performed by always twisting the infrared-colored fluorescent filament 8 into the specific yarn 3. The use of low-power infrared laser radiation equipment for counterfeiting is not as common as for UV-irradiated black light 7, so that counterfeiters are extremely sensitive to the fact that the woven label 10 is double-locked. It becomes difficult.

  FIG. 6 shows the slide fastener 12 that is engaged with two tape portions 16 and 16 each having a dentition 56 on the opposite side surface and is opened and closed by a slider (not shown). The tape portions 16, 16 are generally woven by a known narrow loom such as a needle loom. The specific yarn 3 is woven as warp in at least one of the tape portions 16. The dentition row is an aspect in which individual dentitions 56 made of metal or plastic are clamped on the side edge of the tape, or a series of resin coils are sewn on the side edge of the tape.

  The slide fastener 12 is drawn out from a fastener automatic manufacturing apparatus (not shown) and wound in a roll shape. The fastener 12 has a long shape in which the tape portions 16 and 16 having the dentitions on the opposite side surfaces are engaged with each other. After the slide fastener 12 is cut to a predetermined size, an upper stopper is attached to one end and a lower stopper or an opening is attached to the other end.

  What is necessary is just to sew the obtained slide fastener 12 to a predetermined | prescribed location in clothing, such as moss and blouson. The slide fastener 12 is only a normal slide fastener without sewing the specific thread 3 under visible light after sewing. If the user himself / herself or the transaction person irradiates the ultraviolet light with the black light 7 and further irradiates the infrared light, the specific yarn 3 is colored in a plurality of colors unique to the user and it can be easily confirmed whether or not it is a genuine product.

  The hook-and-loop fastener 58 shown in FIG. 9 is made of nylon fiber, and the hook-like element 60 and the loop-like element 62 are mixed and erected. In the long surface fastener tape, a plurality of rows of element standing portions having a width of 21 mm are woven with a width of 4 mm on a wide base fabric body, and a specific thread 3 is woven into each element standing portion. After the adhesive is applied to the back surface of the base fabric body and the hook-shaped element 60 is formed or heat-treated, it is cut by heating in the middle of a gap having a width of 4 mm without the element.

  The edge stitching portions 66, 66 wrapping the both side edges of the base cloth 64 make the needle thread tightening in the overlock sewing machine strong and the lower thread tension relatively weak so that the lower thread side Envelop the edges. In this stitch format, the width of the edge stitching portion 66 is set to 1.5 mm. The lower thread is a multifilament bulky thread that completely hides the relatively hard side edges.

  In order to obtain the hook-and-loop fastener 58, the fastener tape having both side edges sewn is further heat-cut in the lateral direction one by one with a separate heat-cutting device (not shown). What is necessary is just to sew the obtained surface fastener 58 in a predetermined | prescribed location in clothing, such as a coat and a blouson. When the hook-and-loop fastener 58 is sewn on the clothes, the skin of the wearer is prevented from being damaged, and the sweater and the inner shirt are not fluffed. The hook-and-loop fastener 58 is merely a normal hook-and-loop fastener without sewing the specific thread 3 under visible light after sewing. If the user himself / herself or the transaction person irradiates the ultraviolet light with the black light 7 and further irradiates the infrared light, the specific yarn 3 is colored in a plurality of colors unique to the user and it can be easily confirmed whether or not it is a genuine product.
