Description

Title of the invention: Jacquard woven label with 2D code technical field

[0001] The invention relates to the technical field of Jacquard weaving, and more particularly to the field of Jacquard weaving of labels such as for ready-to-wear clothing or textile accessories such as bracelets. Previous art

[0002] It is known from the prior art of Jacquard woven labels featuring two-dimensional codes such as QR codes.

[0003] Such a QR code weave can be used on clothing to make information available to the user. It can be used for traceability (logistics or anti-counterfeiting). It can also be adapted for the manufacture of identification bracelets for access to campsites or festivals, for example.

[0004] Document JP3132067 describes such a woven label. However, the ranges given for yarn selection and label weave are neither precise enough nor suitable for reliably and repeatably producing Jacquard woven labels. For example, one difficulty in weaving labels with a two-dimensional code lies in the fact that fabric is flexible, and deformation of a two-dimensional code hinders its readability. Furthermore, the crossing of yarns during weaving can distort the code and also impair readability.

[0005] Document WO2013 / 001380 also describes a Jacquard woven label featuring a QR code. The teachings in this document have the same shortcomings.

[0006] Furthermore, a 2D code presents a number of data points (square modules, or pixels) correlated to the amount of information encoded. If the code encoded by the 2D code is too large (in data volume), because it contains too many characters, then the 2D code comprises many pixels.

[0007] When mapping this 2D code, a choice must then be made between: - the good readability of the 2D code, by imposing a minimum pixel size, and therefore, the minimum size of the woven 2D code; and - the maximum size that we want to give to this 2D code, especially in the case of a label whose width rarely exceeds 4 cm or 5 cm.

[0008] The smaller the woven 2D code, the more regularly the threads defining the pixels must be crossed to form said pixels. Too many thread crossings lead to distortion of the fabric (and therefore of the 2D code), which impairs its readability. In cases of excessive information density, this Too many crossings can even cause jams on the loom.

[0009] There is therefore a difficulty in weaving 2D codes in a reliable and repeatable manner.

[0010] Jacquard label weaving featuring data is also known variables. That is to say, for a batch of labels manufactured: - they share fixed data such as a brand's logo, and - they present variable data that are specific to one or more labels, such as clothing sizes or a serial number.

[0011] Variable data can be unique (serialization) or repetitive (for example, several labels may show the same clothing size). A production batch of variable labels can include at least 50 different combinations of fixed and variable data, or at least 100, 500, or even 1,000 different combinations. In some traceability applications where the variable data is unique, a production batch can include at least 10,000, or even 100,000 different combinations, since each label is unique.

[0012] When manufacturing variable data labels, a difficulty arises in the card layout of the woven labels: from an industrial perspective, this card layout cannot be performed manually, as the working time would be multiplied by the number of variable data points. Automatic card layout software is used.

[0013] Automatic carding has the advantage of accelerating the carding of a large number of labels; however, it has the disadvantage of not being as high-quality and optimized as manual carding. For example, automatic carding can lead to an insufficient or, conversely, excessive number of weft thread connections. This results in defects during weaving (loops of threads that are too loose, distortion of the woven pattern). These defects can render a woven 2D code unreadable. Furthermore, the readability is not constant and depends on the smoothing and weaving of each variable data point: there is a risk that the majority of labels will be readable, but that a significant and unacceptable proportion of labels will be unreadable.

[0014] The difficulties of weaving 2D codes are therefore exacerbated in the case of Jacquard weaving of 2D codes with variable data, and even more so if the codes are unique.

[0015] In traceability applications, all delivered labels must be legible. Furthermore, the functionality of the proposed traceability solution, based on woven labels, must be guaranteed for at least the entire lifespan of the products concerned: this could be around ten years for an accessory such as a handbag.

[0016] A fortiori, the operation of the proposed traceability solution must be guaranteed for at least the entire lifespan of the traceability application itself (i.e., from the date the first traced item was put into circulation until the end of life of the last traced item placed on the market). This duration could therefore be around fifteen, or even twenty years.

[0017] The weaving of woven labels with a 2D code must therefore be stable and repeatable over a long period even in the case of automatic smoothing, which is not possible with prior art solutions. Description of the invention

[0018] The invention aims to solve the problems of the prior art, by proposing a label compatible with the Jacquard weaving of two-dimensional codes (“2D codes”), in a reliable and repeatable manner, and preferably with variable data.

[0019] For this purpose, a Jacquard woven label has been developed comprising a two-dimensional code, encoding an identifier.

[0020] According to a first embodiment of the invention: - the warp thread density of the label is between 38 and 70 threads per cm; - the warp yarns of the label have a count between 50 and 110 dtex; - the thread density in the weft of the label is between 65 and 125 threads per cm; - the weft yarns of the label have a count between 20 and 65 dtex.

[0021] According to a second embodiment of the invention: - the warp thread density of the label is between 75 and 140 threads per cm; - the warp yarns of the label have a count between 40 and 72 dtex; - the thread density in the weft of the label is between 55 and 105 threads per cm; - the weft yarns of the label have a count between 20 and 100 dtex.

[0022] This multiple choice of yarn density and warp and weft thread count makes it possible to obtain a label: - of sufficient density to be rigid enough (and prevent deformation of the QR code, which would impair its readability); - of sufficient definition and resolution to allow the code to be readable. - while ensuring reliable and repeatable weaving.

[0023] In particular, the use of finer yarns for the warp as well as for the weft allows for more flexible yarns, deforming the weave less at the level of the QR code (where the links are particularly numerous).

[0024] To prevent the code's information density from becoming too high, the code comprises an alphanumeric string of between 30 and 45 characters, for example, 35 characters. In one embodiment, the identifier is a unique identifier. This embodiment allows for the creation of labels suitable for traceability or authentication applications.

[0025] Advantageously, the unique identifier comprises an alphanumeric string, preferably consisting of 9 to 12 characters. This number of characters is more than sufficient to obtain a large number of unique identifiers (more than 28x10" identifiers).

[0026] In one mode, the alphanumeric string simultaneously comprises digits and letters, preferably selected from a predetermined list. Mixing alphabetic and numeric characters within the identifier makes it possible to obtain an average amount of data to encode. Indeed, digits are encoded in fewer bytes than some alphabetic characters. Systematically mixing digits and letters avoids having: - codes composed solely of digits (corresponding to few bytes, therefore easy to encode, and QR codes that are easy to weave together); and - codes composed of letters only (corresponding to more bytes, therefore less easy to code, and QR codes less easy to weave).

[0027] Preferably, the characters are selected from a predetermined list which makes it possible to avoid the lightest characters to code (little data) and the heaviest characters to code (more data).

[0028] In order to be compatible with the most commonly used labels on the ready-to-wear market, the 2D code has dimensions between 9 and 25mm, or between 15 and 20mm, or between 10 and 12mm.

[0029] Advantageously, the weft threads comprise ground threads and broach threads, and floats of broach threads located on the reverse side of the label are tied to the level of floats of weft threads located on the front of the label at a rate equal to or dividing by the rate of the weft thread weave, in order to increase the rigidity of the label. Thus, the 2D code is less distorted and its reading is facilitated.

[0030] The 2D code optimized according to the aforementioned characteristics makes it possible to manufacture a batch of labels that present variable data within the batch, such as variations of an item according to its size or color. Preferably, the identifier of each label is unique, which allows for the implementation of individual item traceability applications.

[0031] The invention also relates to a method for manufacturing a batch of labels, comprising steps consisting of: - obtain an initial list of identifiers, defining a manufacturing batch; - to create a card layout for the batch of labels to be woven; - weaving the labels; - cut the woven labels using an automatic cutting machine; - package the cut-out labels. This process makes it possible to obtain woven labels with a variable 2D code (because (from the first list), according to the aforementioned advantages.

[0032] Advantageously, the identifiers are unique and the process includes, between the cutting step and the packaging step, an automatic unit control step of the unique identifier, in order to verify the readability of the unique identifier of each of the labels, and: - if the inspection is successful, the label is automatically transferred for packaging; or - in case of non-compliance of the control, the label is set aside so as not to be packaged. In this way, any manufacturing defects that may have occurred and that impair the readability of the label will be detected, and only readable labels will be delivered to customers.

[0042] With reference to [Fig. 1], the invention relates primarily to a Jacquard woven label (1) having a two-dimensional code (2). In the remainder of this document, reference will be made to a QR code (2), without this being limiting.

[0043] Woven labels (1) are primarily intended for the clothing, ready-to-wear, textile, and apparel market. In this sector, the size of the labels (1) rarely exceeds 8 cm on each side. Most often, the width of the labels (1) is between 10 and 50 millimeters, and their visible length is between 4 and 8 cm.

[0044] A QR code (2) for the aforementioned markets therefore has a typically wide between 9 mm and 25 mm, or between 10 mm and 20 mm or even between 10 mm and 15 mm for labels (1) of smaller dimensions.

[0045] In a particular embodiment, the width of the QR code (2) is between 12 and 16 mm, not including a possible silence zone bordering the QR code (2) to facilitate its reading by a device such as a smartphone. This value represents a satisfactory compromise between the readability of the QR code (2), the amount of information it can encode, and the most common label widths (1). This dimension therefore constitutes a standard suitable for the markets concerned.

[0046] When a label (1) of this type has a QR code (2), the dimensions of the latter are therefore limited by the dimensions of the label. On the other hand, the content of the QR code (2) depends on the encoded information.

[0047] In this case, the more information a QR code (2) needs to encode, the more square modules (or pixels) it must contain. It follows that for a QR code (2) of a given size, the greater the amount of information to be encoded, the smaller the size of the pixels in the QR code (2).

[0048] There may therefore be an incompatibility between the required resolution of the QR code (2) (based on its maximum size and the amount of information to be encoded) and the resolution of the Jacquard weave (which is defined by the texture and the yarn count of the yarns used): - Using wires that are too thick does not allow us to obtain the resolution necessary to weave the code (2). - Using a weave that is too loose provides a flexible fabric on which the QR code (2) can be distorted and therefore difficult to read. - Weaving pixels that are too small results in too many, too dense, thread crossings, which can distort the fabric during weaving and complicate the code's readability. Alternatively, the label (1) might not be woven because of jams on the loom.

[0049] The invention essentially lies in the suitability found between the thread count and the texture of the label.

[0050] In the first embodiment: - the warp yarn density of the label (1) is between 38 and 70 yarns per cm; - the warp yarns of the label (1) have a count between 55 and 105 dtex; - the thread density in the weft of the label (1) is between 65 and 120 threads per cm; - The weft yarns of the label (1) have a count between 20 and 65 dtex. In particular, the weft yarns may include ground yarns and broach yarns of different counts, selected from: - the first yarns, with a count between 20 and 40 dtex; and - second yarns, with a count between 35 and 65 dtex.

[0051] In the second embodiment: - the warp thread density of the label (1) is between 75 and 140 threads per cm; - the warp yarns of the label (1) have a count between 40 and 72 dtex; - the thread density in the weft of the label (1) is between 55 and 105 threads per cm; - The weft yarns of the label (1) have a count between 20 and 100 dtex. In particular, the weft yarns may include ground yarns and broach yarns of different counts, selected from: - the first yarns, with a count between 20 and 40 dtex; and - secondary yarns, with a count between 35 and 65 dtex; and - third yarns, with a count between 55 and 100 dtex.

[0052] The choice of one mode or the other is mainly based on the desired warp yarn density range, which imposes a particular construction of the loom (size and arrangement of the Jacquard mechanism, position of the heddles, heddle line, preparation of the beam).

[0053] Selecting the warp yarn density range allows for weaving with varying degrees of density. The selection of other parameters (warp and weft yarn count, weft density) is then carried out.

[0054] Such choices of texture and titration provide a fabric rigid enough to ensure the readability of the code, and has a resolution suitable for weaving QR codes.

[0055] Advantageously, the construction of the first embodiment is carried out according to the following preferred selections: - the warp thread density of the label (1) is between 45 and 65 threads per cm, or between 50 and 60 threads per cm, or between 52 and 57 threads per cm, and is for example 54 threads / cm; - the warp yarns of the label (1) have a count between 65 and 95 dtex, or between 72 and 88 dtex, or between 76 and 84 dtex and is worth for example 80 dtex; - the thread density in the weft of the label (1) is between 75 and 110 threads per cm or between 83 and 100 threads per cm, or between 87 and 97 threads per cm, and is for example 92 threads / cm; - The weft yarns of the label (1) have a count between 25 and 60 dtex, or between 27 and 55 dtex, or between 29 and 53 dtex, and are, for example, 50 dtex. In particular, the weft yarns may include ground yarns and broach yarns of different counts, selected from: - the first yarns, with a count between 24 and 36 dtex, or between 27 and 33 dtex, or between 29 and 32 dtex, and worth, for example, 30 dtex; and - second yarns, with a count between 40 and 60 dtex, or between 45 and 55 dtex, or between 48 and 53 dtex, and worth for example 50 dtex.

[0056] Advantageously, the construction of the second embodiment is carried out according to the following preferred selections: - the warp thread density of the label (1) is between 86 and 130 threads per cm, or between 97 and 120 threads per cm, or between 103 and 113 threads per cm, and is for example 108 threads / cm; - the warp yarns of the label (1) have a count between 44 and 66 dtex, or between 50 and 60 dtex, or between 52 and 58 dtex and is worth for example 55 dtex; - the thread density in the weft of the label (1) is between 64 and 96 threads per cm or between 72 and 88 threads per cm, or between 76 and 84 threads per cm, and is for example 80 threads / cm; - The weft yarns of the label (1) have a count between 24 and 90 dtex, or between 27 and 84 dtex, or between 29 and 80 dtex, and are, for example, 50 dtex. In particular, the weft yarns may include ground yarns and broach yarns of different counts, selected from: - the first yarns, with a count between 24 and 36 dtex, or between 27 and 33 dtex, or between 29 and 32 dtex, and worth, for example, 30 dtex; and - second yarns, with a count between 40 and 60 dtex, or between 45 and 55 dtex, or between 48 and 53 dtex, and worth, for example, 50 dtex; and possibly - third yarns, with a count between 60 and 90 dtex, or between 68 and 84 dtex, or between 72 and 80 dtex, and worth for example 76 dtex.

[0057] In a particular embodiment, the label (1) has variable data. This means that within the same batch of labels, not all have the same code. This is used in several situations: - Serialization of label (1) with unique code (2), so that it can be used in traceability or authentication applications; - Traceability of manufacturing batches, in which several labels (1) have an identical code (2) corresponding to a family of articles, for example the same model of clothing (model, color, size).

[0058] Examples of batch manufacturing of variable data labels are given below.

[0059] Table 1 illustrates the principle of a manufacturing batch in which each label (1) presents a unique identifier (here composed of eight alphanumeric characters).

[0061] Table 2 illustrates the principle of a manufacturing batch in which each label (1) has an Internet address (“URL” for “Uniform Resource Locator”). In particular, each URL is unique.

[0063] Table 3 illustrates the principle of a manufacturing batch in which 13 clothing labels (1) are to be manufactured, several labels (1) being able to have the same identifier.

[0065] In each case, the identifiers and URLs are coded by a QR code.

[0066] From an industrial point of view, it is not feasible to make the individual carding Each of these variable data labels is manually drawn, even when using dedicated software. In the case of variable data, the fixed data—that is, the label background and any brand logo—is drawn manually. However, the variable data on the label (1) is processed by automatic drawing software.

[0067] Figure 2 illustrates an excerpt from a card layout. It shows a representation of the intersections of the warp and weft threads constituting the label. The higher the density of warp and / or weft threads, the more thread intersections there are. The same applies to the resolution of the QR code (2): the greater the amount of information to be encoded, the higher the resolution, as explained previously.

[0068] When putting a batch of variable data labels (1) into production, there is therefore a risk that some variable data may correspond to an excessive volume of data, which can lead to labels (1) that are either unmanufacturable or unreadable. Since card insertion is automatic, these labels (1) will not be detected.

[0069] To overcome this drawback, the identifier encoded by the QR code (2) comprises a limited number of characters. In a preferred mode, the identifier is encoded using eight alphanumeric characters. This number of characters provides several billion possibilities, which is more than sufficient in the technical field considered. However, this limited number of characters ensures that the resolution of the QR code (2) will not exceed what is acceptable from the point of view of weaving.

[0070] The different alphanumeric characters are not encoded with the same amount of data depending on their encoding format: - for example, in the "ASCII" encoding table, according to the English acronym "American Standard Code for Information Interchange", a character is coded on 1 byte; - in the "UTF-8" encoding table, according to the acronym for "Universal Character Set Transformation Format - 8 bits", a character can be encoded on 4 bytes.

[0071] Thus, the character A is coded on a single byte in ASCII; whereas it is coded on 4 bytes in UTF-8.

[0072] In order to limit the volume of data required to encode the code, it only includes characters from the ASCII table. The ASCII table contains fewer characters than other tables; however, the number of available characters is sufficient to obtain, for example, several trillion unique 8-character identifiers.

[0073] The woven label generally presents the identifier in alphanumeric form, in order to overcome difficulties in reading the QR code (2), or simply to allow it to be read by eye.

[0074] In order to avoid dyslexia or reading errors, visually similar characters are avoided. For example, the number 0 and the letter O, or the number 1 and the letter 1, are easily confused.

[0075] Preferably, the alphanumeric characters are therefore chosen from a reduced list, comprising the following characters: A, B, C, D, G, H, J, N, P, S, T, W, Z, a, b, d, e, f, h, k, m, r, t, x, y, 2, 3, 4, 5, 7, 8, 9.

[0076] Choosing characters from a predetermined list therefore allows: - to limit the volume of data needed to encode the code, because the characters can be encoded according to a lighter character encoding standard; - to avoid dyslexia problems or reading difficulties when a user tries to read the woven identifier in alphanumeric form.

[0077] Although the number of available characters is more limited, this list makes it possible to generate more than 100 billion unique 8-character identifiers.

[0078] In one mode, QR codes (2) encode an alphanumeric string which includes a unique identifier according to the aforementioned characteristics. This is, for example, a URL.

[0079] Even if the alphanumeric string is longer, it is still possible to control the density of the QR code (2) within the production batch, since the variability of the amount of information to be coded is controlled in the same way as explained above.

[0080] Advantageously, the coded URLs can be shortened URLs (fewer characters, therefore less data to code), pointing to longer redirection URLs (more characters, therefore more data to code).

[0081] With reference to Figures 3 and 4, two QR codes (2) are shown, each encoding an eight-character alphanumeric code. It can be seen that the amounts of data required to encode these two identifiers are sufficiently close that the QR codes (2) have the same resolution. In this case, they each comprise 21 pixels on each side.

[0082] With reference to Figures 5 and 6, two identifiers are shown in URL format, each comprising eight characters. It can be seen that, since the amount of encoded information is greater than for the identifiers in Figures 3 and 4, the resolution of the QR codes (2) has also increased: each of these QR codes (2) now comprises 25 pixels on each side. In the case of fixed-size QR codes (2) (for example, 12 mm), the QR codes (2) in Figures 5 and 6 have smaller pixels than the QQR codes (2) in Figures 3 and 4.

[0083] Nevertheless, the two URLs encoded in Figures 5 and 6 include a similar amount of information, so that the two QR codes (2) have the same resolution.

[0084] Figure 7 illustrates a Jacquard weave with two weft yarns: a ground (F) and a brocaded (B): - the ground yarn (F) is woven according to a 3 twill weave: it leaves three warp yarns (Cl, C2, C3), then takes one warp yarn (C4), leaves three warp yarns again (C5, C6, C7) and so on. - the broaching thread (B) is not supposed to be visible at this level of the label (1), and is therefore reverse (V) of the label.

[0085] In theory, the brocaded thread (B) could be left floating across the entire width of the label (1), but the floats would then form long loops of thread that could hinder the label manufacturing process. In practice, the brocaded threads (B) on the reverse side (V) are therefore picked up at regular intervals, for example, approximately every 10 to 20 warp threads.

[0086] In order not to affect the background weave, the stitch (B) is taken at a rate that is a multiple, equal to, or a divisor of the rate of the background weave (F). In the case of 3-ply twill (4-ply warp), the stitch (B): - is taken from a warp thread (C2); then - is left on 7 warp threads (C3-C9); then - is taken from the chain wire (CIO), and so on.

[0087] The rhythm of the brocade (B) is therefore 8 warp threads, which is a multiple of the rhythm of the background weave (4 threads).

[0088] With reference to [Fig.8], it may be necessary to increase the rigidity of the label (1), without, however, exceeding the aforementioned yarn density and yarn count ranges. To achieve this, it is possible to modify the weave structure to increase the number of yarn links.

[0089] In order that these additional ties do not change the appearance of the label (1) from the front (R), ties are added only one level of floats of brocaded threads (B), on the front (R).

[0090] In the given example, the rhythm of the paperback (B) is now 4: - he takes a wire (C2), - leaves three wires (C3-C5), - takes a wire (C6) and so on.

[0091] The stitching pattern of the binding (B) is then 4 threads, which is equal to the stitching pattern of the background thread (F): from the front (R), the stitching patterns of the binding (B) remain hidden by the floats of the background thread (F) and the appearance of the label (1) is preserved. However, the number of stitching patterns has been doubled, and therefore the rigidity of the label (1) has also been doubled.

[0092] If it is necessary to further increase the rigidity of the label (1), it is possible to make bindings of the staple (B) according to a divisor rhythm of the background rhythm (F).

[0093] With reference to [Fig. 9], the stitching pattern (B) is now 2 threads. The rigidity of the label (1) is further increased.

[0094] The examples given illustrate the binding at the level of floats of the ground yarn (F), but it can be any weft yarn: ground (F) or broached (B).

[0095] It is observed that it is therefore possible, by implementing the aforementioned characteristics, to weave batches of labels (1) presenting QR codes (2) encoding unique identifiers, in a reliable and repeatable manner, because the identifiers to be encoded can be diversified (several billion possibilities), while ensuring that the quantity of information to be encoded is controlled (limited disparity in the quantity of data, which guarantees the stability of the resolution of the QR code).

[0096] The invention also relates to a Jacquard weaving method for labels (1) having a 2D code. The method comprises the following steps: - obtain an initial list of identifiers, defining a manufacturing batch; - to carry out a card layout of the batch of labels (1) to be woven; - weaving the labels (1); - cut the woven labels (1) using an automatic cutting machine; - package the cut-out labels (1).

[0097] The aforementioned technical characteristics of the label (1) guaranteeing the reliability of the weaving, this process makes it possible to obtain batches of Jacquard woven labels (1) with QR code (2), including when the woven data are variable.

[0098] In particular, this process is adapted to weaving a unique QR code (2). In order to perfect To ensure the reliability of the process, it is possible to add, between the cutting and packaging stages, an automatic unit control step for the unique identifier, in order to verify the readability of the unique identifier on each label, and: - if the inspection is successful, the label (1) is automatically transferred for packaging; or - in case of non-compliance of the control, the label (1) is set aside so as not to be packaged.

[0099] In this way, it is possible to deliver a batch of labels (1) for which readability is guaranteed for all of the labels.

[0100] Furthermore, the label (1) and the method can be shaped differently from the examples given without departing from the scope of the invention, which is defined by the claims.

[0101] In particular, the two-dimensional code can be shaped differently from a QR code (2), and can be of any type suitable for the present application.
