Definitions
- the present invention relates to a textile product with a coded seam and to a system for producing the textile product. Furthermore, the present invention relates to a system and a method for reading information data of a textile product.
- AD:IG: mr in a manner that is obvious or understandable to the consumer.
- a textile product which comprises a textile material and a seam sewn into the textile material.
- the seam has a predetermined pattern which is indicative of information data relating to the textile product and which is optically detectable.
- the textile product can, for example, be a piece of clothing, such as a T-shirt, a shirt, a sweater or trousers.
- the textile product can also be shoes, gloves or a belt.
- Textile products according to the invention can also be used in other areas in addition to being worn on the human body.
- the textile product can be used as a cover for seats, airbag balloons or fittings.
- the textile product is, for example, a medical product, in particular a textile one. Medical products often cannot be printed with data or product information. For this reason, the The data encoding according to the invention can be used both for quality control (e.g. sampling to determine whether the correct textile product is in the correct packaging) and for identifying product properties.
- the textile material of the textile product can, for example, consist of a woven fabric made of synthetic or natural materials.
- the textile material thus has a specific knitted form, in particular a fabric or a fleece.
- the textile material can comprise textile leather, which is used, for example, for covering seats, handbags or suitcases. Accordingly, the coded seam according to the invention can, for example, be sewn onto a leather-like textile material.
- seams are a method for joining fabrics, forming finishes, preventing fraying or creating decorative elements. In doing so, they largely meet basic functional or design-oriented criteria.
- the seam according to the invention can consist of a synthetic or natural yarn.
- the seam can be made from different types of seam and correspondingly different types of shape.
- the seam can, for example, form a zigzag seam, an overlock seam, a step seam, a cast-on seam, a draft seam or a tack seam.
- Other seam shapes or types can also be used to form the pattern for displaying information data.
- the seam is used simultaneously to join fabrics, to form an elastic seam or the seam forms a hem finish.
- the seam can be designed to meet various desired design criteria.
- the yarn that forms the seam can have a uniform color or a different color gradient or areas with different colors. Furthermore, the seam thickness or the thickness of the yarn that forms the seam can be selected to be constant or variable.
- the seam is produced in particular in an automated process, for example with the system according to the invention for producing the textile product.
- the predetermined pattern can, for example, be formed such that the seam has a specific stitch width, which is defined between two spaced-apart punctures in the textile material. Areas of the seam can, for example, have a first stitch width and other areas a second stitch width, wherein the corresponding areas of the stitch width are indicative of certain information. Furthermore, the pattern can be formed from a specific waveform (for example with a corresponding amplitude), wherein each waveform (round waveform with a predetermined curvature or also angular zigzag waveform) is indicative of a certain information. As explained below in further examples, another seam can also form the pattern or the color of the seam and/or the thickness of the seam can vary accordingly in order to depict complex information in a pattern.
- information data about the textile product is depicted in a pattern that is formed by a corresponding seam, and in particular is depicted in an encrypted or encoded manner.
- the desired information data is depicted in the pattern using a specific algorithm.
- Information data can then only be read by those who have knowledge of the algorithm, so that the information data cannot be read by any observer, thus ensuring a high level of security against forgery.
- the information data can reflect a variety of content.
- the information data can provide information about the original manufacturer. Accordingly, for example, it can be checked whether the textile product really comes from the manufacturer stated on the label, for example.
- Other information can also be provided, such as the material of the textile or the quality of the textile.
- information on the certificate of origin can be provided with information on whether the cotton for the active ingredient comes from organic production, does not contain any colors that are harmful to health, or whether the raw material was harvested in accordance with international standards, for example without child labor.
- the seam is permanently and unchangeably connected to the textile material.
- the seam cannot be subsequently changed after the thread has been sewn in without leaving recognizable traces in the textile material.
- areas of the seam or in particular the beginning or end of the seam can be glued or welded to the textile material, so that loosening the seam leads to damage to the textile material.
- the information encoded according to the invention can no longer be modified after the sewing process without leaving traces and thus represents a secure or highly secure feature for data encoding.
- the information encoding in a seam according to the invention makes it possible to achieve a high degree of security against forgery. If the information is coded accordingly, at least a partial unraveling and re-sewing of the seam is necessary for a modification.
- the predetermined pattern can also be defined based on a local formation of the seam in relation to a reference feature of the textile material.
- the reference feature is in particular a width, a shape and/or a course to a fabric feature, in particular an edge, a hem, a buttonhole, a corner, a predetermined pattern and/or a connecting material of the fabric workpiece. In this way, it can be determined in which area of the seam in relation to a distance to a hem, a buttonhole or a quilting pattern certain information data is stored in the pattern of the seam.
- the seam has a first information area, which has the predetermined pattern, and a second information area, which has the predetermined pattern, wherein the first information area is formed at a distance from the second information area.
- the seam thus has redundant areas in which the pattern is depicted, in particular identically. If the pattern in the first information area is disturbed, for example due to a defect in the first information area or due to a distortion of the first information area (for example due to wear or stretching of the textile material due to prolonged wear), this information of the pattern can be read out from the second information area. This ensures secure availability of the information encoded in the pattern.
- the readability of the encoded information (i.e. the reliability of the reading and decoding process) can be increased by means of appropriate additional measures. For example, a Hamming distance greater than 1 can be selected. This means that several optical changes of an encoding feature can alternate with one another so that this digitally corresponds to a change from 0 to 1 or 1 to 0. This reduces the susceptibility to errors when delivering the information due to changes in the pattern.
- the seam is designed such that the predetermined pattern on a surface, in particular is optically detectable exclusively on a surface of the textile material, in particular by means of a camera or a camera of a mobile device. Due to the information coding according to the invention, the embedded information in the pattern is present on the surface of the textile material and thus also on a surface of the textile product. This allows the information to be read out later (without destroying the product) by means of optical means, in particular by means of a camera, preferably with the camera of a mobile device.
- Certain seam types or combinations of seam types can be used so that the pattern or an information encoding is shown on one side of the textile material, while the other side of the textile material is free of the pattern and correspondingly of optical features of the information encoding.
- the outside of clothes or the top of bathroom rugs can be free of features, while the inside or bottom has encoded information in the form of the pattern.
- a sewing machine can be used for this, for example with different needles, which can be changed automatically, for example.
- two separate sewing machines can also be provided in order to generate different seam shapes on each top side. For example, a straight seam can be sewn with one needle on a first side of the textile material and a zigzag-shaped seam on the opposite second side of the textile material.
- the textile product has a further seam (or a further plurality of seams) which is sewn into the textile material, wherein the further seam has the predetermined pattern or another predetermined pattern which is indicative of further information data relating to the textile product.
- the seam and the further seam are in particular formed at a distance from one another. If the seam and the other seam at a distance form an identical pattern, this redundant design of the pattern can provide greater readability. The information is thus redundantly encoded. It is advantageous if a geographically distant location on the textile product is chosen for the repetition of the information (in particular a different seam), so that in the event of local partial damage to the textile, the information is still retained.
- the predetermined pattern can thus be formed by means of at least the seam and the further seam lying next to one another.
- the pattern can thus be formed by both or a further plurality of seams.
- a higher information density can thus be represented in the pattern due to the different shape of the seams.
- an additional seam can be sewn in next to the one seam (main seam), which encodes information, or several seams lying next to one another can form the pattern and be used accordingly for information coding.
- the distance between the seams can be used as an information coding element that also forms the predetermined pattern.
- Information encoding with more than one seam running next to one another has the advantage of a higher data density per seam length, which is particularly advantageous with larger amounts of data.
- a distance between the seam and another seam and/or the formation of the seam and the other seam on an inner and/or outer edge of the textile material can be used to define the predetermined pattern and to read out the information data.
- the shape/type of seam can be a carrier of information, but also the distance to the fabric edge (i.e. the distance between the seam and the outer edge of the textile, i.e.
- the seam to the end of the hem typically the seam to the end of the hem
- the seam distance to the inner end of the textile material actual end of the textile material in the case of a single-fold open-edge hem or inner fold line in the case of a double-fold hem
- the textile material distance between the seam and the inner end of the fabric/edge of the fabric [in the case of a folded hem, the end of the fabric is on the other side of the seam than the outer edge of the textile]
- the information data is selected from one of the group consisting of opaque data, numbers, order numbers, source material identifiers, production lot identifiers, serial numbers, security codes, key and reference numbers (or of course a combination of these data types or information data).
- opaque data refers to a data type whose physical representation is either unknown or irrelevant.
- the data structure of an opaque data type is not defined solely on a boundary area.
- the concrete type of representation remains opaque (hidden) for the user and the visible implementation is incomplete.
- Opaque data types i.e. non-transparent data types, are often used to implement abstract data types.
- the information data comprises a security code comprising a cross sum, redundancy data and/or a checksum, which is indicative of a correct reproduction of the information data.
- the encoding and subsequent decoding of information data via the predetermined pattern, which is formed by means of the fabric seam can be carried out as a transmission in a noise-disturbed channel (Shannon theory, Shannon-Hartley law).
- the interference is not typical white noise, as in an electrical communication channel, but results from various sources of interference, particularly during decoding.
- the textile material may be distorted, part of the seam may be covered by dirt, the reading camera may have high thermal noise (or another reason for blurriness, such as a dusty lens).
- either the information can be redundantly encoded in the textile material, particularly at several seams, or a larger Hamming distance can be selected, which improves the detectability of errors, or a coding can be selected in which, for example, two or more stitches of a seam are made in a certain way so that the code value of a bit is encoded.
- the information data have at least one information content which can be represented in particular by at least one bit, wherein the seam is designed such that at least two pattern properties are formed in the predetermined pattern in order to represent the information content.
- a pattern property can be defined, for example, by defining predetermined stitch properties, such as the stitch width or the seam shape between two stitches of the seam, in order to represent information, for example a bit (0/1).
- predetermined stitch properties such as the stitch width or the seam shape between two stitches of the seam
- several stitch properties represent a bit (example of information content).
- a certain bit sequence (0100, 1000, 0010, etc.) can be represented via correspondingly repeating pattern sections, and thus represent a readable, compilable code.
- the control unit can accordingly have a compiler which translates source codes of the bit sequence as machine language into a form that can be executed by a computer.
- the seam has an initial character and/or an initial position (e.g. opposite a defined seam edge, label, cross seam) which represents a visually recognizable start and/or a reading direction for reading the predetermined pattern.
- an initial character and/or an initial position e.g. opposite a defined seam edge, label, cross seam
- This enables a recognition option for determining the reading direction (in the seam) or the start of reading (of information in a seam).
- This can be realized, for example, by an additional information element (initial character, initial position indicative of a start of reading) or a sequence of information elements, for example a synchronization element after an unmodulated seam zone and the start of the encoded information.
- the reading direction for reading the predetermined pattern can be determined based on a reading definition, wherein the reading definition can be defined in particular by taking into account the inside and/or outside of the textile material and/or by taking into account the distance of the seam to an edge of the textile material.
- the reading definition can be defined in particular by taking into account the inside and/or outside of the textile material and/or by taking into account the distance of the seam to an edge of the textile material.
- the seam or the start of the seam and the reading direction of the seam can also be defined without the presence of an initial character.
- the reading direction can be determined based on a convention. This can be defined by taking into account the inside and outside of the fabric and/or by taking into account the location of the fabric edge.
- the following convention can be defined: On the inside of the fabric, the fabric area with more fabric is referred to as the west and the fabric area with less fabric (hem side) is referred to as the east, whereby the reading direction is then northward.
- the inside or outside can be recognized by detecting the shape of the seam. because the top and bottom of a seam are usually visually distinguishable.
- the seam is made of a yarn which forms a higher contrast under predetermined lighting conditions than with standard illuminant D65.
- Standard illuminant D65 is defined by the CIE standard lighting and corresponds to the average daylight in a midday sky at a north window. The spectrum has a most similar color temperature of 6504 Kelvin. This standard light is used, for example, as a white point for sRGB, Adobe RGB and the PAb/SECAM TV standard.
- the yarn according to the invention for the seam can, for example, be designed in such a way that its dye absorbs or reflects a specific UV component under standard light D65 and has a specific color temperature.
- the seam is made of a yarn which has a variable yarn thickness and/or a predetermined color gradient as a yarn property, so that the predetermined pattern can be formed at least partially from a yarn thickness variation and/or the predetermined color gradient along the yarn.
- a predetermined pattern is thus generated in which the information data is encoded by varying the yarn thickness and/or by a color variation integrated in the yarn gradient.
- the yarn thickness variation for example, the upper and lower threads of a seam can be of different thicknesses.
- the seam is formed from at least two different yarns, wherein the yarns have different yarn properties that are optically detectable, so that the predetermined pattern can be formed using the different yarns.
- the different yarn properties can be defined in particular by different yarn thicknesses, different yarn colors (in particular also in the area of the light spectrum that is not visible to the eye), and/or different yarn material.
- the yarn is designed in such a way that the yarn property is not visible under standard light type D65.
- a yarn is used for the predetermined pattern and the corresponding data encoding which forms a particularly good contrast to the sewn textile material. This allows for easier decoding with simpler (mobile phone) cameras.
- This can also be supported by means of a dye which reacts to a special lighting light composition (e.g. UV-active color) or the resulting yarn color is based on the color mixture of two dyes which produce the desired design color under normal white light, but when illuminated with special light one of the several dyes forms a particularly clearly recognizable contrast.
- a special lighting light composition e.g. UV-active color
- Yarns dyed in this way have a different color under special lighting conditions than, for example, under standard light D65. This corresponds to a phase of natural daylight with a most similar color temperature of approx. 6504 K.
- information can also be encoded by combining different yarns which are the same color under D65.
- the seam is formed from an upper thread and a lower thread, wherein the predetermined pattern is formed from a predetermined variation of the upper thread and the lower thread.
- the upper thread is a part of the yarn which is an upper part of a sewing machine.
- the upper thread tension is used to slow down the unwinding of the thread from the spool, for example.
- the lower thread is the part of the thread that forms the lower side of the seam when sewing with the sewing machine.
- the lower thread is typically on a spool that is inserted into the sewing machine under the needle plate. If the upper thread and lower thread of the seam are used to define the predetermined pattern, this in turn allows (particularly when combined with other coding methods) a higher data density per length or is a design element used for information coding.
- the textile product has a decoding element, in particular a label or tag, which is permanently and unchangeably connected to the textile material.
- the decoding element has an encryption rule by means of which the information data from the predetermined pattern can be decrypted.
- the decoding element forms the encryption rule in particular in a serial number or a non-fugible token.
- the decoding element accordingly has a code as an encryption rule.
- the encryption rule can specify which information can be read from the specific stitch spacing of the seam or the specific yarn thickness of the seam in the predetermined pattern.
- the encryption rule can specify that 3 stitches in a defined length section of the seam result in the bit value 1 and 2 stitches in a defined length section result in the bit value 0.
- This type of encryption rule can be shown accordingly on the label or tag.
- the predetermined pattern can be displayed and the encryption rule can be displayed on the decoding element simultaneously or sequentially.
- the encryption rule is now applied to the recorded predetermined pattern and the information data is read out accordingly. Since the encryption rule is also fixed directly to the textile material, it is not necessary to obtain the encryption rule via an external server or database unit, but can be done locally via a mobile handheld device, for example.
- a non-fungible token is a "cryptographically unique, indivisible, irreplaceable and verifiable token that represents a specific object, be it digital or physical, in a blockchain.
- a label can be sewn into the seam of the textile material.
- the seam or the predetermined pattern and the label as a decoding element can contain information that complements each other.
- a code/encryption rule (e.g. a barcode or a QR code) can be attached to the label, which establishes the link between the predetermined pattern and the information data or seam information.
- the code forms the encryption rule, so to speak, for how the predetermined pattern can be decrypted and the information data can be read out accordingly.
- the code can, for example, be attached to the label at a later date and take the seam information or the actual pattern shown into account. In this way, (extended) information that cannot be changed without causing any damage can be linked to the
- a system for producing the textile product described above has a control unit with a database unit in which predetermined patterns are stored which are indicative of information data of the textile product. Furthermore, the system has a sewing machine which is coupled by means of the control unit in such a way that at least one seam with the predetermined pattern indicative of information data of the textile product can be sewn into the textile material of the textile product.
- the sewing machine can be controlled fully automatically by the control unit, which has knowledge of the manufacturing data of the textile product on the one hand and of the information that is to be reproduced in the seam on the other.
- the control unit has knowledge of the algorithm with which the desired information is reproduced in the pattern. Accordingly, the control unit can control the sewing machine to form the seam based on the pattern to be reproduced.
- a handling robot with an effector can be used, on which a handling mechanism is provided.
- the handling mechanism is configured in such a way that at least one layer of the textile material is laid flat, e.g. on a work surface of a work table, and the layer of material is stretched out without creases.
- the handling robot has the effector, to which the corresponding handling mechanism for holding the textile material is attached, in particular replaceably.
- the handling robot is attached to the floor or work table with a stationary robot base in order to introduce corresponding forces into the corresponding system.
- the handling robot can also be configured in such a way that the robot base is designed to be movable along the floor.
- a robot arm can be arranged between the effector and the robot base, which has for example one or more joints in order to control the effector into a desired position.

- the handling robot is designed to handle or manipulate the fabric layers and to move and position them accordingly relative to the sewing machine.
- the handling robot enables a machine-controlled position change option in more than one axis and/or along a translational position change of the fabric layers.
- the handling robot and in particular the sewing machine can be controlled by the control unit in such a way that the seam can be reproduced with a specific pattern on the textile material.
- (Digital) information can be encoded with the pattern formed by the seam according to the invention. Digital information is thus embedded in the seam of a textile product, which can later be read out digitally.
- the system for producing the textile product has a fabric guide system for guiding the textile material during sewing, wherein the control unit is coupled to the fabric guide system and the sewing machine in such a way that the sewing of the predetermined pattern can be implemented by controlling the guidance of the textile material.
- the control unit is coupled to the fabric guide system and the sewing machine in such a way that the sewing of the predetermined pattern can be implemented by controlling the guidance of the textile material.
- an effector as part of a fabric handling system on a handling robot or a sewing frame as a fabric handling system in which the textile material is clamped usually moves the textile material during sewing.
- the fabric guide system and, for example, a fabric transport system in the sewing machine therefore have less displacement resistance when guiding the seam, which leads to a better seam appearance and accordingly to a more precise predetermined pattern.
- the color printer can be an inkjet printer and can color the yarn with fine color jets of a dye.
- the color printer can be designed to apply a dye of a specific color.
- the color printer can also be designed to apply several different dyes with different colors and compositions to the yarn in sections. Mixtures of the dyes can also be implemented in a targeted manner using the color printer.
- the seam can thus be made from a yarn whose color gradient is adjusted during the sewing process.
- This can be achieved, for example, with a color printer, in particular an inkjet printer, before, after or in the sewing machine.
- the color printer can be arranged so that the yarn is fed through the color printer before sewing and the printer prints the information as a color gradient onto the yarn during sewing (in particular in real time).
- This color gradient can vary in such small sections that it is inconspicuous and/or invisible to the human eye.
- the dye can be chosen outside the range of the light spectrum visible to humans and/or has such a fine contrast and/or is so small in size that this is not trivially visible when viewed. The information is thus encoded in the color gradient.
- a system for reading information data of a textile product described above has a reading device for optically detecting the seam with the predetermined pattern, which is indicative of Information data relating to the textile product. Furthermore, the system has a readout control unit having a database unit, wherein the database unit has encryption rules by means of which information data can be read out from the detected predetermined pattern.
- the reading device has, for example, a camera which can take an image of the pattern, which is then analyzed, for example, by means of image processing software in the reading control unit.
- the reading device can, for example, be a mobile handheld device, such as a smartphone.
- the reading control unit can, for example, have a corresponding processor for processing the image data and for processing the encryption rules, which are stored, for example, in the database.

- the information data can specify a manufacturer A, wherein the verification data specifying the original manufacturer specifies manufacturer B.
- information data can, for example, specify a synthetic substance, while the verification data surrounds a natural substance. Accordingly, counterfeits can be identified by comparing the decrypted information data with the verification data provided in the database. In other words, by comparing the information data with the Verification data can be used to check the authenticity of the textile product and as a result determine whether the textile product was actually manufactured by manufacturer A, was actually manufactured from a specific textile material (e.g. organically grown textile material) which was, for example, harvested in country A. If all information data matches the verification data, a certificate confirming the authenticity of the textile product can be displayed (e.g. on a smartphone) or printed out using the readout control unit.
