Description

[0001] The present invention relates to a method for producing a textile item, in particular a garment, and to a device for producing a textile item, in particular a garment, according to the respective preambles of claims 1 and 10.

[0002] A key element of the present method is, in a first step, the provision of a template unit that provides a shape and / or a size and / or a textile fabric. In the context of the present invention, "provision" can refer to the actual, haptically structural provision of a haptically perceptible textile fabric, or the textile fabric may exist only virtually, that is, in digital form. For example, such a textile fabric can be digitally represented by various data points stored in the template unit. Such storage might, for instance, take place within a database system.

[0003] In the next step, a textile fabric is provided, which is formed from a textile base fabric.

[0004] This step can mean that the textile fabric is first woven, either structurally or virtually, for example, together with the electrically conductive threads. This would mean that the electrically conductive threads are not added to the base textile fabric afterward, but are woven into it during the weaving process itself. In this case, the electrically conductive threads can replace individual threads or sections of thread in the actual textile fabric.

[0005] Here too, the textile material can either be provided in a haptic, structural form or only virtually stored in the form of data in the specification unit and / or loaded into the specification device.

[0006] MÖHRING, U. [et.al.]: Challenge of Smart Textiles, presentation at the 8th Food Science Seminar of BLC and TUD, Dresden, March 12 and 13, 2013, shows the integration of components, development of efficient positioning and contacting technologies for components, development of textile-based components, such as textile sensors, highly flexible electrodes, textile heating systems, and textile solar cells. DE 10 2010 017 684 A1 shows that flexible antennas for RFID transponders can be manufactured particularly easily by producing a fabric tape with at least two conductive warp threads arranged next to each other and at least one non-conductive thermoplastic weft thread, then cutting the warp threads, creating at least two fabric sections, and heating the weft thread in at least one end area of ​​the warp threads of at least one of the fabric sections in order to fix the weft thread on the end area of ​​at least one fabric section.

[0007] DE 10 2017 203 643 A1 relates to a method for manufacturing thermoelectric modules of a thermoelectric device. Simplified and cost-effective manufacturing of the modules is achieved by providing an electrically conductive substrate and equipping it with a thermoelectrically active semiconductor, wherein the substrate equipped with the semiconductor is then divided into several parts, each forming such a module, wherein each module comprises a substrate section and a semiconductor section. The invention further relates to a method for manufacturing such a thermoelectric device, such a module, and such a device.

[0008] Ribbon weaving. In: Wikipedia, The Free Encyclopedia. Revision as of 3 June 2019. URL: https: / / de.wikipedia.org / wiki / Bandweberei shows: Ribbon weaving is a branch of the textile industry in which smooth and patterned narrow fabrics of all kinds, as ribbons and straps with selvedges on both sides and widths of 5 to 400 mm, are produced using ribbon looms.

[0009] A key element of the present invention is that, in a next step, the textile base material is divided into at least two spatially independent textile segments separated by at least one cutting mark by means of a production unit, wherein the textile segments, after their joining, result in the textile piece specified by the predefined unit, in particular a garment, wherein, in a next step, electrical conductive threads are incorporated into the individual textile segments by means of corresponding predefined parameters of the predefined unit, wherein, according to the invention, the electrically conductive threads do not cross the cutting mark and also do not run on it, at least partially.

[0010] In other words, such a cutting mark is not cut at any point, so the entire process relies on uncut electrical conductors. Cutting the electrical conductors has been shown to result in material defects and hot spots at the cut end during use of the electrical guide.

[0011] Preferably, at least one cutting mark extends at least partially through the textile fabric, which is preferably a flat material. For example, each textile segment has at least one cutting mark as part of a boundary edge.

[0012] For example, each electrically conductive thread is positioned at least two millimeters away from each cutting mark. This ensures that the electrically conductive thread is not damaged during the cutting process.

[0013] For example, a textile segment has at least two electrically conductive threads, preferably running parallel to each other. The distance between these threads can be at least one millimeter. However, the paths of the electrically conductive threads can also be curved, circular, or ellipsoidal.

[0014] For example, at least two sub-segments contain electrically conductive threads of different lengths. These threads can have different lengths within a single sub-segment, and / or threads from different sub-segments can have different lengths.

[0015] In other words, in the above-mentioned process, a cutting pattern is first applied to a preferably flat textile fabric by means of the production unit and / or such a textile fabric is virtually overlaid by means of a virtual pattern (for example, the pattern is only virtually placed over the textile fabric), whereby this cutting pattern is then cut up according to the cutting lines stored in the cutting pattern, so that the then cut textile segments can subsequently be joined together to then produce a textile piece as claimed here.

[0016] The electrically conductive threads serve to connect electrically operated sensors and / or other electrically operated elements. These elements can generally also include one or more devices for measuring pressure and / or humidity.

[0017] According to the invention, these sensors are applied, at least partially, to the textile segments along the cutting lines before cutting, for example, by printing them on, and are brought into electrically conductive contact with the electrically conductive threads. After the individual segments are joined together to form the textile fabric, i.e., for example, the garment, the free ends of the electrically conductive threads can be electrically connected to a power supply unit, according to the invention.

[0018] Alternatively, the electrically operated sensors and / or other electrically operated elements can also be applied to the textile item, for example the garment, only after it has been created.

[0019] The device for measuring pressure and / or humidity, which is also described here, comprises at least one sensor for measuring pressure and / or humidity, wherein the sensor comprises at least one capacitor with at least two electrodes, which are arranged relative to each other, in particular in a horizontal direction, along and on a support material, in particular a flexible one, wherein at least one dielectric layer is arranged between the electrodes.

[0020] The horizontal direction is preferably a main extension direction of the flexible support material. The support material can be the textile base fabric.

[0021] In this context, "flexible" means that the carrier material is at least partially bendable and therefore elastic.

[0022] In particular, the carrier material can be a woven fabric or another type of clothing fabric, such as polyester.

[0023] The dielectric layer thus separates the two electrodes in a horizontal and / or a transverse direction perpendicular to it.

[0024] For example, on a side facing away from the substrate material, at least one electrode and / or dielectric layer is arranged, at least partially, and at least one moisture layer is arranged, at least partially permeable to liquid and / or absorbent, wherein the at least one electrode and / or dielectric layer is arranged in a transverse direction between the substrate material and the moisture layer, so that a capacitance is at least partially changed by the liquid that at least partially affects the dielectric layer, wherein a processing unit is set up and provided for measuring and / or storing this change, so that a capacitive moisture sensor is created.

[0025] A capacitive humidity sensor is essentially a capacitor whose dielectric preferably consists of a hygroscopic polymer layer that absorbs or desorbs moisture depending on the humidity of the ambient air until an equilibrium state (diffusion gradient = 0) is reached. The dielectric constant of the polymer material changes as a function of the moisture content. The task of the processing unit includes, among other things, determining the relative humidity as accurately as possible, preferably also from a measured ambient temperature and the humidity-dependent capacitance value of the sensor.

[0026] According to at least one embodiment, the device for measuring pressure and / or humidity comprises at least one sensor for measuring pressure and / or humidity, wherein the sensor comprises at least one capacitor with at least two electrodes, which are arranged in a horizontal direction along and on a, in particular flexible, support material relative to each other, wherein at least one dielectric layer is arranged between the electrodes.

[0027] For example, on a side facing away from the substrate material, at least one electrode and / or dielectric layer, at least partially, is arranged, and at least one, at least partially, liquid-permeable and / or liquid-absorbing layer (= moisture layer) is arranged, wherein the at least one electrode and / or dielectric layer is thus arranged in the transverse direction between the substrate material and the moisture layer, so that a capacitance is at least partially changed by the liquid that at least partially affects the dielectric layer, wherein a processing unit is set up and provided for measuring and / or storing this change, so that a capacitive humidity sensor is created.

[0028] The moisture layer can be formed with a dielectric material. The material of the moisture layer can be different from the material of the waterproof layer.

[0029] The sensor and / or the processing unit can be powered by a battery or a mains power supply.

[0030] Alternatively or additionally, it is possible to generate electrical energy to supply the sensor and / or processing unit using so-called "energy harvesting".

[0031] Energy harvesting refers to the extraction of small amounts of electrical energy from sources such as ambient temperature, vibrations, or air currents for low-power mobile devices. The structures used for this purpose are also known as nanogenerators. Energy harvesting eliminates the limitations of wired power supplies or batteries in wireless technologies.

[0032] Possibilities of energy harvesting: Piezoelectric crystals generate electrical voltages when subjected to force, such as pressure or vibration. These crystals can be arranged on or attached to the substrate. Thermoelectric generators and pyroelectric crystals generate electrical energy from temperature differences. These generators can be attached to or mounted on the substrate. Antennas can capture the energy of radio waves, a form of electromagnetic radiation, and use it for energy generation. Passive RFID tags are an example of this. These antennas can be attached to or embedded in the carrier material. - Photovoltaics, electrical energy from ambient lighting. - Osmosis.

[0033] According to at least one embodiment, the sensor is additionally a capacitive pressure sensor, wherein the processing unit is additionally configured and designed to measure and / or store a change in the capacitor's capacitance caused by external pressure.

[0034] Essentially, a capacitive sensor is a sensor that operates based on changes in the electrical capacitance of a single capacitor or a capacitor system. The influence of the quantity to be measured on the capacitance can occur in various ways, primarily determined by the intended application.

[0035] A capacitive sensor is based, among other things, on the fact that two electrodes, one of which can be the measuring surface, form the "plates" of an electrical capacitor, whose capacitance or change in capacitance is measured, which can be influenced as follows: - A plate is displaced and / or deformed by the measuring effect, which changes the plate distance and thus the electrically measurable capacitance. - The plates are rigid and the capacitance itself changes when an electrically conductive material or a dielectric is brought into close proximity. - The effective plate area changes by shifting the plates relative to each other, as in a variable capacitor.

[0036] In order to better detect even small changes, the actual measuring electrode can often be surrounded by a shielding electrode that protects the inhomogeneous boundary region of the electric field from the measuring electrode. This results in an approximately parallel electric field between the measuring electrode and the usually grounded counter electrode, with the known characteristics of an ideal plate capacitor.

[0037] A capacitive pressure sensor is, in particular, one in which the change in capacitance due to the deflection of a diaphragm and the resulting change in the plate spacing is evaluated as the sensor effect. For example, the diaphragm is the aforementioned dielectric material or the individual capacitor electrodes, which can be designed, in particular, in the form of a plate. In other words, in such an embodiment, a capacitive humidity sensor is combined with a capacitive pressure sensor in a novel way, but without these components forming separate elements or two separate sensors. Rather, the present embodiment is a "two-in-one" concept in which the same sensor functions as both a humidity sensor and a pressure sensor.

[0038] According to at least one embodiment, the carrier material is a woven fabric, in particular in which electrical conductors for electrical contacting of the sensor and the processing unit are woven.

[0039] For the purposes of the invention, a woven fabric is therefore a fabric that has been woven manually or mechanically on the basis of individual threads.

[0040] The electrical conductors can therefore be integrated into a fabric in addition to the usual fibers and fabric strands, or they can replace individual fabric strands that form the fabric network.

[0041] Depending on the spacing and properties of the individual threads (twisted, bulky, etc.), very loose fabrics, such as bandages, or dense fabrics, such as brocade, can be created. Longitudinally elastic fabrics are achieved through the use of rubber threads (more often ribbons) as warp threads or crimped and bulky yarns. These are stretched, processed, and then contract when at rest. Bulky yarns consist of textured, i.e., crimped, synthetic fibers. The crimping alters the properties of the synthetic fibers. The yarns spun from these fibers are very elastic and voluminous and offer good thermal insulation.

[0042] For example, the substrate material can be part of the upholstery fabric of a seat, in particular a vehicle seat or an office chair. In this respect, the sensor, or preferably the entire device, can be applied to or integrated into the upholstery fabric of such a seat.

[0043] For example, the processing unit is set up and designed to record the individual humidity and pressure values ​​and to determine at least one characteristic value from a combination of the individual humidity and pressure values, from which it can be derived which individual (with weight and / or size) is currently occupying the vehicle seat.

[0044] For example, the weight of a person can be derived and determined from the pressure measurement taken by the processing unit. Similarly, the moisture emitted by the person to the sensor can be measured, with the corresponding value being, for example, the product of the relative humidity value and the weight determined by the processing unit.

[0045] If such a parameter exceeds a corresponding limit, the processing unit can issue a warning, particularly via a connection to the vehicle's electronics. This warning could indicate that the seat is overoccupied or that the driver is sweating excessively. However, this warning could also be replaced by a display indicating the type of occupant using the seat. Occupancy type could be a weight classification of the respective user, or it could be whether the user is an animal, a person, or even an object. Therefore, the processing unit is preferably integrable into the vehicle's display electronics, or at least connectable to such an electronic system.

[0046] It is conceivable that the processing unit connects to a receiving unit of the vehicle, for example via Bluetooth or another wireless connection, and that the respective characteristic or limit value and / or the respective warning and / or the respective identification of the user is displayed on a display of the vehicle.

[0047] Alternatively or additionally, it is conceivable that these individual values ​​and / or identifications could also be retrieved and / or displayed externally. For example, the car could be monitored for overload by an external controller.

[0048] For example, a data connection can be used to link the processing unit with an airbag trigger unit, allowing the processing unit to control and / or regulate the trigger unit, particularly regarding the airbag deployment time. Additionally and / or alternatively, the processing unit can provide an airbag controller unit with data, for example, regarding the occupant type, position, and / or weight of the vehicle seat user.

[0049] This data can be used to adjust the triggering time and sequence of the airbag to the user, thus preventing personal injury to the user.

[0050] According to at least one embodiment, at least one electrode and / or dielectric layer is printed on the substrate material or on a layer arranged on the substrate material, in particular a water-impermeable layer, or applied using a thin-film process.

[0051] This means that at least one element, preferably both the electrode and the dielectric layer, is printed onto the substrate material or onto a layer applied between the sensor and the substrate material, preferably electrically non-conductive and further preferably waterproof, by means of a printing process.

[0052] The printing process could, for example, be an inkjet process.

[0053] For example, the processing unit is applied to the substrate in the same way as the sensor. It is conceivable that the processing unit, or at least one layer of it, particularly a conductive one, is printed onto the substrate. Data communication between the processing unit and the sensor can then occur via the aforementioned conductive traces. These conductive traces can be woven into the fabric, at least partially, but preferably completely, or even form individual fibers of the fabric itself.

[0054] For example, at least one electrode is designed as a flat surface. This means that the thickness of the electrode is negligible compared to its surface area. Such an electrode can therefore be manufactured, in particular, using a printing process.

[0055] Alternatively, the thickness of at least one electrode can be a maximum of 5 mm. The printing process can be applied multiple times so that at least two, but preferably more, individual printed layers are stacked on top of each other.

[0056] Furthermore, the electrode can also be arranged on the substrate material using a 3D printing process. 1. The FDM process (Fused Deposition Modeling) Alternative names: Fused Filament Fabrication (FFF), Fused Layer Modeling (FLM)

[0057] The process involves the layer-by-layer application (extrusion) of a material through a hot nozzle. The consumable material, in the form of a long wire (filament) on a spool, is fed by the feed unit into a print head, where it is melted and deposited onto a build plate. The print head and / or build plate are movable in three directions, allowing layers of plastic to be applied one on top of the other. 2. The SLS process (Selective Laser Sintering)

[0058] Unlike sintering, where powdered materials are fused together under heat, SLS selectively uses a laser (alternatively an electron beam or infrared beam). Only a specific portion of the powder is fused together.

[0059] A thin layer of powder is applied to the print bed by the coating unit. The laser (or other energy source) is then precisely aimed at specific points within the powder layer to create the first layer of the print data. During this process, the powder is partially melted and then solidifies again upon slight cooling. The unmelted powder remains around the sintered areas and serves as support material. After a layer has solidified, the print bed lowers by a fraction of a millimeter. The coating unit then moves across the print bed and applies the next layer of powder. The second layer of the print data is then sintered by the laser (or other energy source). In this way, a three-dimensional object is created layer by layer. 3. Three-Dimensional Printing (3DP)

[0060] The 3DP process works very similarly to selective laser sintering, but instead of a directed energy source, a print head moves across the powder. This head deposits tiny droplets of binder onto the underlying powder layers, bonding them together. Otherwise, this process is identical to SLS. 4. Stereolithography (SLA)

[0061] Instead of plastic filament or powdered printing material, the stereolithography process uses liquid resins, so-called photopolymers. These are hardened layer by layer by UV radiation, thus creating three-dimensional objects. For this process, the build platform is lowered step by step into the resin bath. There are also variants (so-called PolyJet processes) that do not use a whole bath of liquid resin. In these, an epoxy resin is applied drop by drop from a nozzle and immediately cured by a UV laser. 5. Laminated Object Manufacturing (LOM)Alternative name: Layer Laminated Manufacturing (LLM)

[0062] The process is based neither on chemical reactions nor on a thermal process. It involves cutting a film or sheet (e.g., paper) along its contour using a separating tool (e.g., a knife or carbon dioxide laser) and gluing the layers together. Lowering the build platform then creates a layered object made of glued, overlapping films.

[0063] One or more waterproof layers and / or the moisture layer can be applied in the same way and / or thickness as the electrode.

[0064] According to at least one embodiment, the moisture layer completely covers the condenser.

[0065] This can mean that the moisture layer, to the outside, i.e. in the transverse direction, demarcates and seals off the sensor to the outside, so that the sensor is arranged between the moisture layer and the substrate material.

[0066] According to at least one embodiment, the sensor has at least one further capacitor which is arranged in the transverse direction below or above the capacitor and is spaced apart from the capacitor by a further waterproof layer on or below this further waterproof layer, so that a capacitor stack is formed.

[0067] The additional capacitor can be constructed in the same way as the first capacitor and can also be arranged on the further waterproof layer in the same way as the first capacitor.

[0068] Using such a capacitor stack, the sensor technology can be refined particularly easily. Specifically, with two sensors forming the capacitor stack, both sensors perform the same tasks, but each sensor takes individual measurements, which are then combined to calculate an average value. For example, each of the two sensors measures the (relative) humidity of the environment, and the average humidity value is then calculated from these two measurements. The same can be done with pressure measurement, allowing the accuracy of the overall measurement, especially a combination of (relative) humidity and pressure measurements, to be significantly improved.

[0069] According to at least one embodiment, the waterproof layer and / or the further waterproof layer forms the dielectric layer at least partially itself.

[0070] This can mean that instead of the separate positioning of a dielectric layer next to the waterproof layer and / or next to the further waterproof layer, this dielectric layer itself is formed by the waterproof layer and / or the further waterproof layer.

[0071] Therefore, generating the dielectric layer using the water-impermeable layer(s) in this way constitutes a particularly simple and cost-effective manufacturing process for a cost-effective device.

[0072] Apart from that, it can generally be provided that the electrodes, the dielectric layer and the waterproof layer(s) are arranged in such a way as to prevent an electrical short circuit in any case.

[0073] According to at least one embodiment, the maximum thickness of the moisture layer is at least 30% and at most 80% of the maximum thickness of the waterproof layer and / or the maximum thickness of the further waterproof layer.

[0074] This not only ensures a particularly flat sensor design, but also guarantees a particularly fast response time to changes in humidity. Moisture acting on the moisture layer from the outside therefore does not have to travel long distances to reach the dielectric.

[0075] Furthermore, the present invention relates to a method for measuring pressure and / or humidity, whereby it should be noted in particular that all features disclosed for the device described above are also disclosed for the method described here and vice versa.

[0076] According to at least one embodiment, the method for measuring pressure and / or humidity initially comprises a first step by which at least one sensor for measuring pressure and / or humidity is provided, wherein the sensor has at least one capacitor with at least two electrodes, which are arranged to each other, in particular in a horizontal direction along and on a, in particular flexible, support material, wherein at least one dielectric layer is arranged between the electrodes.

[0077] According to the invention, on a side facing away from the substrate material, at least one electrode and / or the dielectric layer is arranged, at least partially, with at least one, at least partially liquid-permeable and / or liquid-absorbing moisture layer, wherein the at least one electrode and / or the dielectric layer are thus arranged in a transverse direction between the substrate material and the moisture layer, so that a capacitance is at least partially changed by the liquid at least partially affecting the dielectric layer, wherein a processing unit measures and / or stores this change, so that a capacitive moisture sensor is created.

[0078] The method described above has the same advantages and advantageous features as the device described above.

[0079] According to at least one embodiment, the method for manufacturing a textile item, in particular a garment, comprises a first step in which a specification unit is provided which specifies a shape and / or size or a textile fabric, wherein in a next step the textile fabric is provided which is formed with a textile base material.

[0080] In a further step according to the invention, the textile base material is divided into at least two spatially independent textile segments separated by at least one cutting mark by means of a production unit, wherein the textile segments, after their joining, result in the textile piece specified by the predefined unit, in particular a garment, wherein in a next step electrically conductive threads are incorporated into the individual textile segments by means of corresponding predefined parameters of the predefined unit, wherein the electrically conductive threads do not cross the cutting mark and do not run at least partially on it.

[0081] According to at least one embodiment, pattern segment subdivisions are stored in the input unit, which are selected in particular by a user and the textile fabric is subdivided according to this pattern segment subdivision of the different textile segments.

[0082] The pattern segment subdivisions are therefore either present in a haptic structural form, or, however, are virtual, meaning they are only stored in the specification unit in terms of data technology and can either be actually, i.e., structurally, or virtually laid over the surface of the textile fabric, resulting in a cutting template.

[0083] According to at least one embodiment, the user specifies the shape and / or size and / or the textile material of the textile piece to be produced, and these values ​​are compared with corresponding values ​​clearly defined in the specification, in particular corresponding pattern segment subdivisions, whereby, after these values ​​have matched, the corresponding pattern segment subdivision is selected by the specification unit.

[0084] Alternatively or additionally, if the values ​​specified by the user deviate by a maximum of, for example, 25%, corresponding matching sample segment subdivisions can be selected. If this deviation is exceeded, the default unit can preferably search for a suitable alternative sample segment automatically. If no suitable sample segment exists, it is conceivable that a new sample segment subdivision is defined and generated based on the values, which then deviate significantly from known patterns.

[0085] According to at least one embodiment, the input unit sends the corresponding pattern segment subdivision to the production unit via data communication, wherein the data communication includes data transmission and further wherein the data transmission is based on a binary language or machine language. The pattern segment is therefore visualized by the production unit either structurally haptically or purely virtually.

[0086] According to at least one embodiment, providing the textile fabric includes or is a virtual or technical loading of data of the textile fabric into the input unit.

[0087] In the context of the invention, "virtual" can mean that an element that actually exists structurally is represented purely in terms of data technology.

[0088] According to at least one embodiment, the further production steps are also carried out at least partially, but preferably completely, only virtually and are therefore only available in the form of data, so that during the subdivision of the textile fabric and the incorporation of the electrically conductive threads into the textile fabric by the specification unit and / or by the production unit, a production file is created which contains all relevant data required for the manufacture.

[0089] According to at least one embodiment, the specification unit and / or the production unit sends this production file to a manufacturing machine for the haptic production of the textile piece, so that the manufacturing machine produces the textile piece exactly according to the data contents of the production file.

[0090] Therefore, at the latest in connection with the aforementioned manufacturing machine, a structurally haptic process is provided.

[0091] However, it should be particularly mentioned that the virtual process steps, each of which is technically solved by structural elements (specification unit, production unit), address the technical problem of sending various manufacturing specifications, for example regarding the shape, size, or quality of the textile fabric, to a production unit preferably in a single production file. This virtual step complex, located before the production machine, not only saves work steps but also allows the production machine to be adapted to the individual technical needs of the overall process as well as to the needs of the user.

[0092] The input unit can be a computer comprising a memory chip and a computer chip.

[0093] The same may apply to the production unit.

[0094] According to at least one embodiment, the cutting mark is defined by at least one cutting point on the textile.

[0095] This can also be done structurally, haptically, or virtually. The cutting markings can be laser markings, driving marks, or mechanical markings such as scoring or punching.

[0096] According to at least one embodiment, the textile piece is manufactured without any rejects. This means that on a given textile piece, preferably 90%, more preferably 95%, and further preferably 100% of the available area is formed by the aforementioned textile segments. In other words, such a textile fabric does not include any areas free of such textile segments (no rejects). The textile piece can therefore be manufactured without any rejects.

[0097] Furthermore, the present invention relates to a device for producing a piece of textile, in particular a garment, wherein the device comprises at least one presetting unit which is set up and provided for specifying a shape and / or height and / or a textile fabric.

[0098] According to the invention, the device comprises at least one production unit which is set up and provided for dividing the base textile material into at least two spatially independent textile segments separated by at least one cutting mark, wherein the textile segments, after being joined together, result in a textile piece specified by the preselection unit, in particular a garment, and further wherein the electrically conductive threads can be incorporated into the individual textile segments by means of corresponding preselection parameters of the preselection unit, wherein the electrically conductive threads do not cross the cutting marks and do not run at least partially on them.

[0099] The device described here has the same advantages and advantageous features as the method described above, and vice versa. The present invention is described in more detail below with reference to three figures.

[0100] Identical and similarly functioning components are marked with the same reference symbols, even if these components may be depicted as exaggeratedly large.

[0101] Fig. Figure 1 shows a basic process diagram illustrating the basic sequence of a procedure described here.

[0102] The Fig. Figure 2 shows a more detailed process diagram illustrating the above procedure according to the Fig. 1.

[0103] The Fig. Figure 3 shows a schematic top view of a process based on the method of Fig. 1 and Fig. 2. Segmentation of the textile fabric created before cutting.

[0104] In the Fig. Figure 1 shows a first process step V1, in which the material of electrically conductive threads 4 (visible in the Fig. 3) as well as the material of a textile fabric 10 of a textile base fabric 11 (visible in the Fig. 3 is selected.

[0105] These are fed into a input unit 21 as part of process step V2. Simultaneously, parameters specified by the user for the production of the desired textile piece 1 are also loaded into input unit 21.

[0106] This therefore includes steps V3 and V4.

[0107] In step V5, certain machine conditions and machine properties of a production machine 5 are also loaded into the processing unit 21. In other words, according to steps V1 to V6, the processing unit 21 therefore has all the relevant data for the production of the textile piece 1.

[0108] Processing unit 21 now processes this data and thus creates a production program adapted to textile piece 1 by means of step V7, so that in step V8 the production program can be sent from one production unit to another or to manufacturing machine 5. Alternatively, it is also possible for the program file to be sent to any other production machine or manufacturing machine.

[0109] In other words, in the Fig. 1. A, preferably purely, virtual creation program is presented, which is, however, technically essential in order to operate the production machine 5. In addition, the production program is not only stored in the processing unit 21 in a technically tangible way, but is actually generated by it.

[0110] In the Fig. Figure 2 shows a more detailed internal data processing flow within the specification unit. Steps V1 and V2 are shown again, and it can now be seen that step V21 integrates all data from the... Fig. The data shown in step 1 is initially processed. It can also be seen that this data is then processed, whereby a design simulation or a design verification D1 can take place in step V22, before, after a corresponding design simulation / verification in step V23, this data is fed back into a processing box 250.

[0111] Alternatively or additionally, after the data integration step, this data is also fed into processing box 250 via step V24. Processing box 250 processes and generates the corresponding cutting mark 3 (visible in the Fig. 3) on the respective underlying textile base material 11 and compares the design data obtained in step V25 with a desired design cut profile within the framework of a simulation / verification S1. This design cut profile can in turn be stored in the processing unit 21.

[0112] If any deviations from a desired design cut profile are detected, this design can be adapted in step V26 to an optimal or desired design profile D2, or one stored in processing unit 21. In step V26, a design rule check D3 is performed, and in step V27, a program file D4 is ultimately generated.

[0113] In the Fig.Figure 3 schematically depicts a basic textile material 11, which is subdivided into different textile segments 210. It can also be seen that corresponding conductive threads 4 are woven into the textile segments 210, or that these electrically conductive threads 4 themselves even replace a textile thread of the textile material 11.

[0114] Furthermore, it is crucial that none of the electrically conductive threads 4 cut through or lie on the cutting marks 3, so that the electrically conductive threads 4 do not have any cut surfaces even after the corresponding cutting along the cutting marks 3, for example by means of a laser or a knife.

[0115] The applicant reserves the right to claim all features disclosed in the application documents as essential to the invention, provided that they are novel individually or in combination compared to the prior art.
