Description:
FABRIC LABEL CONTAINING A UNIQUE PIECE OF INFORMATION AND PROCESS FOR MAKING AND STORING IT

Field of the Invention

The present invention concerns the field of the individual identification of items by means of labels made of fabric and anti-counterfeiting systems of labels made of fabric. More in particular, the present invention relates to a label provided with an anti- counterfeiting system and the relative making process.

Known Art

As known, the individual identification of items of clothing or fashion accessories is obtained also by fabric labels containing numerical or alphanumeric strings or codes of mono/two-dimensional types both readable by electronic equipment, such as for example bar codes or QR-codes. These labels and the relative coding are made, for example, by printing processes, such as Thermal Transfer or Ink on Ribbon (TTR) or by inkjet printing.

Such processes are, in fact, to date the only ones able to make big quantities of labels containing variable data readable both by visual recognition and electronic equipment. The Applicant observed that the labels obtained have poor aesthetic attractiveness due to the limitation of the number of colors and/or alignment problems among the colors and/or printing definition problems. Furthermore, the fabric treatment, prior and preparatory to the printing, generally involves such a stiffening of the same to be bothersome to the user (especially in a clothing wherein the label is in contact with the skin), which involves that often the same user removes the label. Furthermore, the labels printed with this technique are not intrinsically protected against the counterfeiting.

In fact, the Applicant observed that the same label can be, with reasonable ease, reproduced unless further anti-counterfeiting elements are applied on it, which make the reproduction more complicated and thus the falsification more evident.

In any case, such techniques complicate the production process and have little effectiveness as these additional anti-counterfeiting elements are not usually serialized. The Applicant has further observed that the coding are placed on the label after the weaving step or the step of making the support of the label, consequently dilating production times of the label and increasing production costs.

A further known technique consists in weaving the serialized information or coding instead of printing them, with interesting tactile and aesthetic results.

But the Applicant observed that this type of label, even if having unique tactile and aesthetic aspects with respect to the previous ones, is very easy to replicate and thus the use thereof doesn't constitute a valid solution to counterfeiting. To compensate this aspect, on said labels holograms are often applied and/or yarns/threads are inserted having optical properties difficult to be reproduced. But the effectiveness of these expedients is relatively low as the additional anti-counterfeiting elements are always identical to one another within a production batch.

Thus, the Applicant found the need to develop a novel label comprising an anti- counterfeiting system and a production process thereof that could resolve the limitations in the technology according to the known techniques mentioned above. Thus, in particular the Applicant found the need to develop a novel label provided with serialized information or coding woven directly in the fabric constituting the label, but not having the counterfeiting limitations of known labels.

Furthermore, the Applicant found the need to develop a novel process for making a woven label, allowing production times and costs to be reduced.

Summary of the Invention

Therefore, in its first aspect the invention relates to a fabric label comprising weft threads and fabric threads woven together so that a first woven pattern is made; said woven pattern being obtained through a specific and controlled arrangement of the weft threads with respect to the warp threads; said label further comprising:

at least one filiform security element arranged in a predetermined position of said label and comprising at least one identification element for each label to be made; said at least one identification element being positioned randomly in said label;

at least one piece of variable information adapted to identify a single label; - the reciprocal position of said at least one identification element (3) with respect to said first woven pattern (2) making at least one element of authenticity of the label (10) itself.

In the scope of the present invention:

The expression "piece of information of variable type" means a piece of information being different for each made label and adapted to identify the label on which is placed. The expression "fabric" means a material obtained by weaving, or inserting, weft yarns in a warp.

By "metallizing" is meant a physical deposition process of a metal in the vapor phase on a film, typically made of plastic.

The present invention, in the above mentioned aspect, can have at least one of the preferred characteristics that are hereinafter described.

Preferably, the filiform security element has a first color and said identification element comprises at least one portion of filiform element of said filiform security element having a color different from the first color of the filiform element.

Advantageously, the filiform security element is arranged at least in the weft threads. Conveniently, the filiform security element comprises at least one fiber, at least one thread, at least one strip, preferably made of film, or a combination thereof.

Advantageously the strip, preferably made of film, can be made of plastic, metal, non- woven fabric paper or a combination thereof.

Preferably, the filiform security element comprises distinctive elements selected among micro-deformations of the filiform security element or a portion thereof, knots, unevenness or thickness variations in the spinning of the filiform security element or a portion thereof, association of micro-objects to the filiform security element or a portion thereof, or a combination thereof.

Conveniently, the filiform security element comprises at least two identification elements each comprising at least one portion of filiform security element having a color different from the first color of the filiform element.

Preferably, the filiform security element comprises a plurality of identification elements each comprising at least one portion of filiform security element having a color different from the first color of the filiform element.

Advantageously, the unique piece of variable information for each label is contained in an alphanumeric code and/or a mono-dimensional code and/or a two-dimensional code and/or a microchip memory.

According to another aspect, the present invention relates to a process for making a fabric label, containing a unique piece of information and for storing such a unique piece of information; characterized by comprising the following steps:

- weaving a fabric piece comprising a first woven pattern made by a predetermined arrangement combination of weft threads with respect to warp threads; said fabric piece having size so that at least one label is made; the weaving step comprising the weaving of at least one filiform security element, comprising at least one identification element for each label to be made, such that said at least one identification element is positioned randomly in a portion of said fabric piece associable to each label to be made;

associating at least one piece of variable information adapted to identify a label for at least one label to be cut;

detecting a reference image, associated with a label, for every portion of first woven pattern; each reference image being adapted to show the reciprocal position of said at least one identification element with respect to the portion of first woven pattern in which it is placed;

storing a reference image or a resumptive parameter of said reference image. Therefore the present invention relates on how to directly insert uncontrollable aesthetic variations in the fabric, in the weaving step, how to use these variations for characterizing each label and how to verify the authenticity of a label by looking at the same aesthetic variations.

The limitations of existing weaving processes do not allow determining the positioning of the filiform security element woven in the label and the result is that its identification elements are positioned randomly with respect to the rest of the label.

The arrangement of the identification elements that are positioned randomly, with respect to the woven pattern, determines a unique label difficult to reproduce.

Preferably, the filiform security element has a first color and said identification element comprises at least one portion of filiform security element having a color different from the first color of the filiform element.

Detailed Description of Embodiments of the Invention

The process according to the present invention allows making a fabric label 10 containing an anti-counterfeiting system, according to the present invention.

The label 10 is made of fabric comprising weft threads and warp threads woven together. The weft threads and warp threads are woven together so that a first woven pattern 2 is made.

The first woven pattern 2 being obtained through a specific and controlled arrangement of the weft threads with respect to the warp threads.

In the label of Figure 1 by way of example, the first woven pattern 2 is depicted as a plain background 20, a heraldic coat of arms 21 having different colors and a writing 22 placed under the coat of arms.

The arrangement of the weft and warp threads can make different decorations and/or writing. The weft and warp threads can be made in any natural, artificial or synthetic material or mixtures thereof which are reciprocally suitable to make a fabric piece 7, by way of example the threads can be made of cotton fiber, viscose yarn, polyester yarn and can be pigmented and shaped according to the weaving capabilities of the loom.

Furthermore, the label 10 has at least one piece of variable information 5, 5', 5" adapted to identify a single label 10.

The variable information 5, 5', 5" can be applied to the label 10 by printing techniques or, preferably, can be woven in the production step of the fabric piece 7.

In other words, in the label manufacturing, during the weaving, the specific arrangement of the weft threads with respect to the warp threads is also making, in addition to the woven pattern 2, the variable information.

The variable information 5 can be depicted as alphanumeric strings, such as the piece of variable information 5' of Figures 1 and 3.

Still alternatively, the variable information 5 can be depicted as two-dimensional codes 5", such as for example the QR-codes of Figure 1 and 3, which are electronically readable by cells of single information elements; the Applicant even made labels also containing two-dimensional codes of Datamatrix or Aztec type and further types of codes could be used without departing from the scope of the present Application. According to another embodiment, the variable information 5 can be contained in one or more microchip physically associated with the label 10. In particular, the microchip could be a RFID tag, more particularly a NFC tag.

Furthermore, the label 10 according to the present invention has at least one filiform security element 4. In the embodiment shown in Figure 1, the filiform security element 4 is arranged as a weft, but could be arranged as a warp without departing from the scope of protection of the present invention.

The position of the security element in the weft is a specific and predetermined position obtained in a controlled way during the production process of the label. Several filiform security elements 4 can be provided for each label 10 and such filiform security elements 4 can be arranged as a weft, as a warp or in both positions.

Preferably, the filiform security element 4 comprises at least one fiber, at least one thread, at least one strip preferably made of film, or a combination thereof. Advantageously the strip, preferably made of film, can be made of plastic, metal, non- woven fabric paper or a combination thereof.

The filiform element 4 can for example be constituted by one single yarn or more yarns kept together, or one or more yarns kept together, for example by twisting to one or more strips made of film.

The filiform security element 4 can be made of natural, artificial or synthetic material or a mixture thereof.

The filiform security element 4 comprises at least one identification element 3 for each label 10. The identification element 3 is positioned randomly in the label 10.

The reciprocal position of the identification elements 3 in the label with respect to the first woven pattern 2, or parts thereof, together with the association between at least one piece of variable information 5, 5', 5" and the reciprocal position of the identification elements 3 with respect to the first woven pattern 2, is making an element of authenticity of the label 10 itself.

Preferably, there are several identification elements 3 for each label 10.

In the embodiment shown in Figures 1 and 3, the filiform security element 4 is a thread having a first base color, while the identification elements 3 are lengths of the same thread having colors different from the first base color.

The identification elements 3 in the embodiment shown in Figure 1 and 2 are represented by lengths 8 or colored portions of filiform element 4.

In detail, the filiform security element 4 has a first color and each identification element 3 comprises at least one portion 8, specifically, a length 8 of filiform element 4 of the security thread having a color different from the first color of the filiform security element 4.

In other words if, as shown in Figure 2, the filiform security element 4 is white, the lengths 8 of different color are black or however not white.

The higher the number of lengths or portions 8 having a color different from the first color, the higher the security level obtained by the label 10 will be.

The lengths 8 having colored thread can be with colors that are not visible to the naked eye but visible in the visible spectrum or IR spectrum when irradiated by UV and/or IR light. Each portion or length 8 having different color of filiform element 4 can have the same longitudinal extent, along the development of the filiform element 4 itself, but higher security level is obtained by providing portions or lengths 8 having different color of filiform element 4 having different extent, as shown in Figure 2.

Each portion 8 having different color of filiform element 4 can have the same color, but higher security level is obtained by providing several portions or lengths 8 having different color of filiform element 4, all having different color.

According to an embodiment not shown, the filiform element 4 can be represented by two yarns kept together by twisting, in this case a first yarn has a first base color of the filiform element 4 and the second yarn has a second color which is different from the first base color and makes the identification elements 3. Thus, the same twisting is making a twisted yarn representing the filiform element 3 having portions with different color due to the alternate twist position of a yarn with respect to the remainder.

The filiform security element 4, as better shown in Figure 2, can have distinctive elements 16 selected among micro-deformations of the filiform security element 4 or a portion thereof, knots, unevenness or thickness variations in the spinning of the filiform security element 4 or a portion thereof, association of micro-objects to the filiform security element or a portion thereof, or a combination thereof.

The distinctive elements 16 can have the same colors or have different colors to one another and with respect to the first base color of the filiform security element 4. The higher the randomness in the distribution of the portions 8 having different color and of the distinctive elements in a filiform security element 4, the more it will be difficult to reproduce the label 10 and thus the higher the protection of the label 10 itself against the counterfeiting.

In the embodiment described by way of example, the process for making a unique fabric label 10 according to the present invention starts with weaving a fabric piece 7. The fabric piece 7 comprises a first woven pattern 2 made by a predetermined arrangement combination of the weft threads with respect to the warp threads.

The arrangement of the weft and warp threads can make different decorations and/or writing. The arrangement of the single weft threads and/or warp threads with respect to all the other threads is controlled by the loom and gives the desired mechanical and aesthetic properties to the fabric.

By way of example, in Figure 2 an embodiment of a fabric piece 7 according to the present invention is shown, each containing three substantially identical first woven patterns 2.

In particular in Figures 1 and 3, the first woven pattern 2 is obtained by controlling the position of the weft threads with respect to the warp threads; in particular, with reference to Figure 3, a fabric piece 7 is shown which comprises three portions 17 substantially with the same woven pattern 2 that are adapted to make three different labels 10. In each portion 17 of the fabric piece 7 intended to become a label 10, by way of example, the first woven pattern 2 is represented by a plain background 20, a heraldic coat of arms 21 having different colors and a writing 22 placed under the coat of arms.

Still with reference to the embodiment shown in Figure 1 is visible how the woven pattern 2 can also be repeated in the fabric piece 7; various fabric pieces 7 can have the same woven pattern, but the highest level of security is achieved when the fabric pieces 7 produced, each adapted to make a batch of labels, have a different woven pattern 2. Preferably, the fabric piece 7 intended to make a label batch comprises a plurality of different woven patterns 2, this can be achieved by controlling the weaving arrangement of the warp threads with respect to the weft threads.

By varying in a controlled way the reciprocal arrangement and positioning of the weft threads with respect to the warp threads, it is possible to obtain, depending on the combination fantasy and the resolution of the weaving, a very high number of woven patterns 2 and consequently a very high number of labels, all of which containing at least one woven pattern 2 different from the other labels 10.

The threads, both as warp and weft, can be made of any natural, artificial or synthetic material or mixtures thereof which are reciprocally suitable to make a fabric piece 7; by way of example the threads can be made of cotton fiber, viscose yarn, polyester yarn and can be pigmented and shaped according to the weaving capabilities of the loom. During the weaving step of the fabric piece 7, at least one filiform security element 4 is inserted, comprising at least one identification element 3 for every portion 17 of fabric piece corresponding to a label 10 to be made. The identification element 3 is positioned randomly in the portion 17 of fabric piece corresponding to a label 10 to be made.

In other words, by inserting the filiform security element 4 in the portion 17 of fabric piece 7 corresponding to a label 10, it is not possible to determine the positioning of its identification elements 3 with respect to the weft threads and the warp threads and, consequently, with respect to the woven pattern 2 or its components.

Preferably, the filiform security element 4 is inserted in the portion 17 of fabric piece 7 corresponding to a label 10 by weaving the same.

In the embodiment shown in Figure 1, the filiform security element 4 is arranged as a weft, but could be arranged as a warp without departing from the scope of protection of the present invention.

Several filiform security elements 4 can be provided for every portion 17 of fabric piece corresponding to a label 10 and they can be arranged as a weft, a warp or in both positions.

Preferably, the filiform security element 4 comprises at least one fiber, at least one thread, at least one strip preferably made of film, or a combination thereof.

The filiform element 4 can for example be constituted by several yarns kept together by twisting or by a thread kept together, for example, by twisting to a strip, the latter being preferably made of film. Advantageously the strip, preferably made of film, can be made of plastic, metal, non-woven fabric paper or a combination thereof.

The filiform security element 4 can be made of natural, artificial or synthetic material or a mixture thereof.

In Figure 2, by way of example a filiform security element 4 not inserted in the fabric piece 7 is shown.

The identification elements 3 in the embodiment shown in Figure 1 and 2 are represented by lengths 8 or colored portions of filiform element 4.

In detail, the filiform security element 4 has a first color and each identification element 3 comprises at least one length 8 of filiform element 4 of the security thread having a color different from the first color of the filiform security element 4.

In other words if, as shown in Figure 2, the filiform security element 4 is white, the lengths 8 having different color are black or however not white.

The higher the number of the lengths 8 having a color different from the first color, the higher the security level obtained by label 10 will be.

Each length 8 having different color of filiform element 4 can have the same longitudinal extent, along the development of the filiform element 4 itself, but a higher security level is obtained by providing lengths 8 having different color of filiform element having different extent, as shown in Figure 2.

Each length 8 having different color of filiform element 4 can have the same color, but higher security level is obtained by providing several lengths 8 having different color of filiform element 4, all having different color.

Preferably, the lengths 8 having different color of filiform element 4 are obtained by dyeing.

Alternatively, the lengths 8 having different color of filiform element 4 are obtained by color printing.

Still alternatively, the lengths 8 having different color of filiform element 4 are obtained by metallizing, for example by metallizing the external surface of the fibers or yarns or film, which constitute the length 8 having different color.

Alternatively, the lengths 8 of different color of filiform element 4 are obtained by colors that are not visible to the naked eye but visible in the visible spectrum or IR spectrum when irradiated by UV and/or IR light.

The lengths 8 having different color of filiform security element 4 can also be represented by the natural aspect of the same filiform security element 4 or its components.

The filiform security element 4, as it is better shown in Figure 2, can have distinctive elements 16, such as knots or crimp.

The distinctive elements 16 can have the same colors or have different colors from one another and with respect to the first color of the filiform security element 4. The distinctive elements 16 can be obtained by micro-deformation.

The higher the randomness in the distribution of the lengths 8 having different color and of the distinctive elements in a filiform security element 4, the more it will be difficult to reproduce the portion of fabric piece 7 intended to become a label 10 and thus the higher the protection of the label 10 itself against the counterfeiting will be. During the weaving step, with the purpose described below, the producer of the label 10 must be accurate in inserting the filiform security elements 4 in the portion 17 of fabric piece 7 intended to become a label 10 so that, when the label 10 is finished, a significant part of the filiform security element 4, and consequently its identification 3 and distinctive 16 elements, are visible.

In a particular embodiment not shown, the filiform security element 4 can be embroidered on the surface of the portion 17 of fabric piece 7 intended to become a label 10.

The Applicant believe that, in the state of the art, during the weaving step being the positioning of the filiform security element 4 in the length direction, with respect to the position of the other threads parallel to it in the plane, precisely and in a controlled way problematic if not even impossible, and being visible the color sequence of the portions 8 having different color or of the distinctive elements 16 it follows that, in the weaving state of the art, it is extremely unlikely to reproduce an area of fabric piece 7 containing a portion of said thread perfectly identical to the other one. Therefore the use of the cited filiform security element 4 allows obtaining a fabric piece 7 containing one or more fabric areas whose peculiarity can optically be recognized.

Subsequently, or at the same time as the weaving step of the first woven patterns 2, on the fabric piece 7 a step of applying at least one piece of variable information 5 to the portion of fabric piece that will generate a label, occurs. The piece of associated variable information 5 is unique for every label 10 to be made and, therefore, is adapted to identify a label 10 and, directly or indirectly, its reference image 12.

The piece of variable information 5 can also be contained in the first woven pattern. Each piece of variable information 5 is adapted to identify only one label. For the identification of the label 10 various variable information 5 can be associated with each label 10 to be made and can contain additional information about the product associated with the label 10 or the production batch of the product and/or label 10. The variable information 5 can be depicted as alphanumeric strings, such as the piece of variable information 5' of Figures 1 and 3.

Alternatively, the variable information 5 can be depicted as electronically readable barcodes; still alternatively, the variable information 5 can be depicted as two- dimensional codes 5", such as for example the QR-codes of Figure 1 and 3, which are electronically readable by cells of single information elements; the Applicant even made labels also containing two-dimensional codes of Datamatrix or Aztec type and further types of codes could be used without departing from the scope of the present Application.

As shown in figures 1 and 3, for every label 10 there can be several variable information 5 adapted to identify a label 10. In the embodiment shown in figures 1 and 3, each label 10 does comprise a first piece of variable information 5' depicted as an alphanumeric string and a second piece of variable information 5" depicted as a QR- code.

Alternatively, variable information 5 can be represented by other coding typologies, without departing from the protection scope of the present invention.

By way of example, the variable information 5 can be stored in one or more microchip physically associated with the label 10. In particular, the microchip could be part of a RFID tag, more in particular a NFC tag, i.e. readable in short distance.

The variable information 5', 5" can be applied to the fabric piece 7 by printing techniques or preferably can be woven in the production step of the fabric piece 7. Advantageously, to reduce the cycle times it is possible to apply the variable information 5', 5" to the fabric piece 7 directly during the weaving step.

In case the fabric piece 7 is intended for making several labels 10, a step of cutting the fabric after the weaving step of the piece 7 needs to be performed.

The cutting step can occur immediately after the step of associating the variable information 5.

Alternatively, the cutting step can occur in a more advanced process step, without departing from the protection scope of the present invention.

Advantageously, the cutting step can be performed by thermal or ultrasound cutting to fix the position of the filiform element 4 with respect to the label 10 itself.

Following the weaving step, the step of associating the variable information 5, and possibly the step of cutting, as shown in Figure 4 a picture of each label 10 is taken, and the image captured by the picture is adapted to show the reciprocal position of each identification element 3 of the filiform security element 4 with respect to the first woven pattern 2 of the label in which it is inserted.

Preferably, the pictures are digital pictures just made by digital technique, and for each label 10 they show the reciprocal position of the identification elements 3 with respect to the woven pattern 2, and in particular the lengths 8 of different color of the filiform elements 4 with respect to the woven pattern 2, thereby in this way a unique image, that cannot be reproduced and will be the reference image 12, is created.

Therefore, once a unique image for every label 10 has been obtained, such an image, named reference image 12, is stored in a database 14 and will be the comparison model to determine subsequently the authenticity of the label.

Further, it is possible to cut the labels 10 coming from the same fabric piece 7, even after making the pictures described above.

Once the labels 10 have been commercialized, it is very simple to ascertain their authenticity and whether they have been counterfeited or not.

Referring to figure 5 when a user, for example a dealer or an inspector or a consumer, has to verify the authenticity of a label 10 and to ascertain whether it has been counterfeited or not, it will be sufficient to detect an image 11 (for example by visual observation) of the same label 10 and compare it visually with a reference one 12 made during the production process.

The reference image 12 is retrieved in the database 14 by the variable information 5 depicted on the same label 10. In the specific example, retrieving the reference image 12 is made possible by inserting the URL encoded in the QR-code in any Internet browser, the URL heads to the machine 13 which is connected to the database 14.

Once the reference image 12 is obtained, the controller will not need to do anything else than verifying the position and shape of the identification elements 3 detected on the physical label with the elements 3 highlighted on the reference image 12, said visual comparison carried out by the controller between the reference image 12 and the detected image 11 of the label in the market will detect the authenticity or not of the label in the market. For the detected image 11 of the label in the market to be authentic, the reciprocal position of the identification elements 3 and/or distinctive elements with respect to the first woven pattern 2 of the detected label 11 must correspond to the reciprocal position between the reciprocal position of the identification elements 3 and/or distinctive elements 16 with respect to the first woven pattern 2 being in the reference image 12. Any misalignment between identification elements 3 and/or distinctive elements 16 and first woven pattern 2 with respect to the positioning of the same elements in the reference image 12 is an indisputable sign that the label 10 is not original.

Alternatively to the storing of the image 12, it is also possible to determine one or both the coordinates of the identification elements 3 and distinctive elements 16 with respect to one or more reference points of the second decoration pattern 4 and storing these coordinates by associating them, directly or indirectly, in the database 14 with one or more variable information 5, thus it is possible to make a detection of the image 11 by any photographic means, by way of example also a simple smartphone 15 or cell phone provided with an integral camera and a specific application, the image is sent to a remote server 13 looking for, in the association database 14 linked to it, the corresponding reference image 12, i.e. the image made of the label 10 itself during the production process. By specific algorithms, software analyzing the image installed on the machine 13 is able to give an evaluation of the authenticity of the label in the market.

In such a case it is also possible to make the authentication by comparing the same coordinates of the identification elements 3 and distinctive elements 16 and those obtained by the reference image 12. In this case, the advantages relative to the reduction of the data amount to be stored for each reference image 12 are manifest. The present invention has been described with reference to some embodiments. To the embodiments herein represented in detail various modifications can be made, comprising the shapes of the woven patterns, anyway remaining in the protection scope of the invention, defined by the following claims.
