Disclosure of Invention

Against this background, with the approach presented here, a textile fabric, an arrangement for generating a non-thermal plasma, a seat cover with a textile fabric, a vehicle with a seat with a seat cover and a method for producing a textile fabric are presented according to the main claims. Advantageous developments and improvements of the device specified in the independent claim are possible as a result of the measures listed in the dependent claims.

With the invention described, textile surfaces can advantageously be equipped with a self-disinfecting function in a particularly simple manner. As a result, for example, the risk of transmission of pathogens can be minimized and unpleasant odors can be neutralized. This can advantageously be achieved with a plasma generating fabric.

A textile fabric is presented, which comprises a textile and an electrode arrangement for generating a non-thermal plasma, the electrode arrangement having a first surface electrode with a first electrical contact for applying a first voltage potential and a second surface electrode with a second electrical contact for applying a second Includes voltage potential, wherein the first surface electrode for generating the non-thermal plasma of the second surface electrode is electrically isolated.

The textile fabric presented here can advantageously be used, for example, to quickly and comprehensively disinfect seats or other surfaces in vehicle interiors or in a person's private environment. An electrode arrangement for generating a non-thermal plasma is used in the textile fabric presented here. A non-thermal or cold plasma can be understood as a partially ionized gas whose mix of electrons, ions, excited molecules and also UV radiation can be used to destroy microorganisms such as bacteria, fungi, viruses, spores or even prions. In addition, the cold plasma can also break down long-chain molecules, which humans can sometimes perceive as an unpleasant odor, and can thus neutralize bad odors. A flexible, flat plasma source is required to generate cold plasma, which can be represented, for example, by surface micro-discharge technology (SMD technology). The non-thermal plasma can be generated at room temperature, for example, by applying the first voltage potential to the first contact and the second voltage potential to the second contact, with the first and second surface electrodes being electrically insulated from one another. The second surface electrode can be, for example, a grounded counter-electrode, which can be arranged, for example, above or below the first surface electrode in relation to the textile.

According to one exemplary embodiment, the textile fabric can comprise a separating layer, it being possible for the first surface electrode to be electrically insulated from the second surface electrode by the separating layer. The separating layer can be formed, for example, from the textile used in the textile fabric, or the separating layer can be an additional, for example also textile and additionally or alternatively flexible layer. For example, the separating layer can be in the form of a very thin spacer fabric, in which the conductive structures of the first surface electrode and the second surface electrode can be worked into both surfaces and can be spaced apart from one another by the structure of the spacer fabric, i.e. by the pile threads, and can be insulated accordingly . Alternatively, for example, the textile fabric can be printed on both sides with conductive material, or two conductive textiles can be laminated to one another, for example with a non-conductive adhesive film. Advantageously, simple and at the same time effective insulation of the first surface electrode from the second surface electrode can be achieved by means of the separating layer.

In addition, the separating layer can be designed to be compressible in order to form a capacitive area sensor together with the electrode arrangement to form. For example, the release liner may compress when a person sits on the fabric. This is useful, for example, when the textile fabric is integrated into a seat cover. In this case, for example, the approach of the first flat electrode to the second flat electrode caused by the weight of the person can be detected by means of a capacitance measurement. If the textile fabric is used, for example, as part of a seat cover, seat occupancy detection can advantageously be activated by using the electrode arrangement as a capacitive area sensor and controlled, for example, by a corresponding control device. This can be used, for example, to advantageously only enable plasma generation when the seat, or all seats in a vehicle, are unoccupied. The additional use of the electrode arrangement as a capacitive area sensor for detecting the presence of persons can thus advantageously optimize the disinfection of the textile fabric or the disinfection of other surfaces arranged on the textile fabric. In addition, an additional sensor, for example for seat occupancy detection, can be dispensed with.

According to a further embodiment, the electrode arrangement can be integrated into the textile or applied to the textile. For example, the electrode arrangement can already be incorporated in the manufacturing process of the textile fabric, for example by knitting, weaving, knitting in, etc. Alternatively, the electrode arrangement can be applied, for example, by printing, coating, embroidering, etc., for example, following the manufacturing process of the textile, for example by a second process step. This has the advantage that the textile fabric can be produced in a particularly cost-effective manner. By subsequently applying the electrode arrangement by printing, coating, laminating, etc., flat electrodes can also be optimally represented.

According to a further embodiment, the first surface electrode can include an additional contact for enabling a current flow through the first surface electrode. A current flow can be generated in the first surface electrode via the first electrical contact and the additional contact. As a result, the textile fabric can be heated. This has the advantage that the textile fabric can have a heating function in addition to the disinfecting function of the electrode arrangement. This can be used, for example, when the textile fabric is used in a seat cover as seat heating. An additional heating device can thus be dispensed with.

According to one embodiment, the textile fabric can be formed as yard goods. For example, the electrode arrangement can already be incorporated into or applied to the textile during the manufacturing process. Advantageously, such yard goods or roll goods can be produced inexpensively and further processed for different cutting patterns and geometries.

The electrode arrangement can be arranged on at least 50% of a width of the textile fabric. For example, the textile fabric can be in the form of strips of fabric or goods sold by the meter. The electrode arrangement can be arranged, for example, in a central area of the strip and can cover, for example, at least 50% or at least 80% of the width of the fabric. For example, narrow strips of, for example, a maximum of 10% of the width of the textile fabric can remain uncovered by the electrode arrangement only in the edge regions of the textile fabric. Advantageously, as large an area of the textile fabric as possible can be disinfected using non-thermal plasma. The electrode arrangement can also be arranged over the entire width of the textile fabric or over an area of less than 50%.

According to one embodiment, the first surface electrode can have a plurality of first conductor tracks and the second surface electrode can have a plurality of second conductor tracks. In this case, the first conductor tracks and the second conductor tracks can cross over. For example, the electrode arrangement can have a diamond-shaped or grid-shaped pattern made of conductive material by means of the conductor tracks crossing one another, which can be applied to the textile or introduced into it. The conductor tracks can be introduced into the textile, for example, by means of insulated yarns, wires, strands or the like, whereby, for example, all conductors running in the same direction can form the first flat electrode and all these crossing conductors can form the second flat electrode. The non-thermal plasma can be generated at the crossing points of the conductor tracks. Since such a diamond or lattice pattern can be continued indefinitely both in the longitudinal direction and in the transverse direction, it is thus advantageously possible to produce a textile semi-finished product in the form of rolled goods and thus also in large quantities at very low prices. With the help of this semi-finished product, patterns can be advantageously cut out and, for example, covers can be produced for a wide variety of geometries, without the need for an individually manufactured electrical system each time dendesign would be necessary. Alternatively, the first conductor tracks and the second conductor tracks can also run parallel to one another, in which case the plasma can be produced in a line along the conductor tracks. Depending on the desired effect and the radius of propagation of the plasma in the textile, different variants are possible.

According to a further embodiment, the first surface electrode and the second surface electrode are arranged in one plane such that the first conductor tracks of the first surface electrode and the second conductor tracks of the second surface electrode intersect in an insulated manner, preferably in the form of a diamond or checkerboard pattern.

The first electrical contact can be formed as a first contact strip along a first edge area of the textile fabric. Additionally or alternatively, the second electrical contact can be formed as a second contact strip along a second edge area of the textile fabric. For example, the electrode arrangement can be arranged between the contact strips, in which case, for example, the first surface electrode can be connected to the first contact strip and the second surface electrode can be connected to the second contact strip. This has the advantage that the textile fabric can be produced inexpensively, for example by the meter.

According to a further embodiment, the first electrical contact can represent the first contact strip applied to a first section of the first surface electrode already arranged on the textile. Additionally or alternatively, the second electrical contact can represent the second contact strip applied to a second section of the second surface electrode already arranged on the textile. The electrical contact can be made, for example, via conductive strips that are integrated or applied to two opposite sides of the textile fabric. These can, for example, be applied to the required points during the manufacturing process or only after the assembly, for example by gluing or laminating on conductive textile strips or by embroidering on conductor tracks, via which contact can be made with an energy source or control electronics. A manufacturing process can advantageously be optimized and carried out cost-effectively as a result.

In addition, an arrangement for generating a non-thermal plasma with the textile fabric described above and with a voltage source for generating the voltage potentials is presented. The voltage source is preferably designed to provide a voltage between 2 kVpp and 10 kVpp at a frequency between 5 kHz and 100 kHz. In a preferred embodiment, the voltage source is designed to provide a voltage of 8 kVpp at a frequency of 5 kHz. In one variant, the voltage source is designed to provide a voltage of 4 kVpp at a frequency of 50 kHz. The non-thermal or cold plasma is generated by applying these voltages to the electrode arrangement with the surface electrodes of the textile fabric arranged insulated from one another. It must be taken into account that the voltage and frequency values are adapted to the design of the electrode arrangement.

In addition, a seat cover with a variant of the previously presented textile fabric or the described arrangement for generating a non-thermal plasma is presented. Such a seat cover can be used, for example, for seats in vehicles, for example in local and long-distance public transport, and in other public facilities such as theaters or congress centers or in waiting rooms and similar rooms in which different people are covered with the seat cover presented here seating can take place. The textile fabric can be used, for example, in the form of so-called inlays, which can be placed directly by the seat manufacturer under the decorative seat cover, for example made of leather, imitation leather or textile, and accordingly additionally protected by it. This has the advantage that there is less likelihood of the functional inlay being damaged by mechanical influences, liquids or the like. Alternatively, the textile fabric can be used to produce a complete seat cover, ideally with the conductor track structure on an inside facing away from the user. Advantageously, the automatic, integrated cleaning function of the textile fabric using non-thermal plasma can quickly and effectively disinfect the seat cover or seat and neutralize odors. In this way, among other things, the risk of infection with pathogens can be minimized. For example, cars, buses, trains, airplanes and other means of transport can be equipped particularly easily with the self-disinfecting function using an already existing, usable energy supply with the seat cover described. However, other areas of life can also benefit from this invention with only very minor changes and thus a high level of profitability. All seating furniture, especially in areas that are very sensitive from a hygienic point of view, such as waiting rooms in doctor's surgeries, hospitals, etc., but also in cinemas, restaurants or canteens, can be used in this way can be cleaned effectively and easily, just like all other textile contact surfaces, such as mattresses in hotels and hospitals or handles.

In addition, a vehicle with at least one seat with a variant of the seat cover presented above and with a control device is presented, the control device being designed to apply the first and the second voltage potential to the electrode arrangement in response to a disinfection signal. For example, the vehicle can be a bus or a train wagon for regularly transporting people. Many means of transport, such as cars, buses, trains, planes or ships, are used at short intervals by numerous different and changing people. With most means of transport, people are transported in a seated position for reasons of safety and comfort. The higher the frequency of use, the greater the risk that the mostly textile-covered seating surfaces will be contaminated with dirt, pathogens and unpleasant odours. This can lead to health damage through infection, or at least to an impairment of travel comfort. When using seating that is covered with a seat cover presented here, the seats can advantageously be regularly and comprehensively disinfected by means of non-thermal plasma. For this purpose, for example, a disinfection signal can always be issued at the end of a journey or a specific deployment time, for example by a user, in order to quickly and effectively disinfect the seats arranged in the vehicle and thus advantageously minimize the risk of infection and unpleasant odors in the vehicle. Since the majority of vehicle seats are now electrically adjustable, corresponding connections under the seats can be used to contact the electrode arrangement of the textile fabric used in the seat cover, for example by means of a Y-coupling. This means that existing vehicles and fleets can also be very easily retrofitted with self-cleaning covers. Rear seats can also be connected to a corresponding connection under the front seat, for example via a cable laid under the carpets. Advantageously, a seat cleaning using non-thermal plasma can be carried out quickly and hardly in a personnel-intensive manner. In the event of a pandemic, the fear of infection and the subsequent avoidance or ban on public or shared transport can be reduced.

According to one embodiment, the vehicle can have a sensor device for detecting contamination of the seat cover, wherein the sensor device can be designed to provide the disinfecting signal in response to the detection. Disinfection can advantageously only be carried out as required and thus in an energy-saving manner.

In addition, a method for producing a textile fabric is presented. In a providing step, a textile, a first surface electrode, a first electrical contact for applying a first voltage potential to the first surface electrode, a second surface electrode and a second electrical contact for applying a second voltage potential to the second surface electrode are provided. In an assembly step, the first surface electrode, the first electrical contact, the second surface electrode and the second electrical contact are assembled with the textile. In this case, the first flat electrode is or is electrically insulated from the second flat electrode in order to generate a non-thermal plasma.

The first surface electrode and the first electrical contact can be provided separately or together, also in one piece. The second surface electrode and the second electrical contact can accordingly be provided separately or together, also in one piece. Each of the surface electrodes can also be provided in one piece or in multiple pieces, already formed in a finished form or to be formed during assembly. Correspondingly, the textile can be provided ready-formed or ready to be formed during assembly. The assembly step can also comprise a number of sub-steps. For example, the surface electrodes and the textile can first be joined together and then the textile having the surface electrodes can be joined to the contacts. According to one embodiment, a completely shaped electrode arrangement and a completely shaped textile are provided in the providing step and joined together in the joining step. In this case, for example, the electrode arrangement can be integrated into the textile in the assembly step, or the electrode arrangement can be applied to the textile in this step.

Electronics that are optionally required to control the cleaning function and, if necessary, other functions can also be incorporated in the further packaging and creation of inlays or seat covers using the textile fabric, for example in the form of an embroidered functional sequin, which is particularly useful for a retro-fit solution would be advantageous, since then only one connection to an external energy source would be required.

In the following description of favorable exemplary embodiments of the present invention, the same or similar reference symbols are used for the elements which are shown in the various figures and have a similar effect, with a repeated description of these elements being dispensed with.

1 shows a schematic representation of a textile fabric 100 according to an embodiment. The textile fabric 100 has a textile 105 and an electrode arrangement 110 for generating a non-thermal plasma. For this purpose, the electrode arrangement 105 comprises a first surface electrode 115 with a first electrical contact 120 for applying a first voltage potential and a second surface electrode 125 with a second electrical contact 130 for applying a second voltage potential, the first surface electrode 115 being electrically insulated from the second surface electrode 125 . The electrode arrangement 110 is formed in such a way that a non-thermal plasma can be generated, with which the textile fabric 100 and surfaces arranged on the textile fabric 100 can be disinfected. Microorganisms such as bacteria, fungi, viruses, spores or even odor molecules can be destroyed using the plasma, which enables hygienic and automated cleaning of the textile fabric 100 .

In this exemplary embodiment, the electrode arrangement 110 is integrated into the textile 105 purely by way of example. In another exemplary embodiment, the electrode arrangement can also be applied to the textile. In this exemplary embodiment, the first surface electrode 115 has a plurality of first conductor tracks 135 and the second surface electrode 125 has a plurality of second conductor tracks 140, with the first conductor tracks 135 and the second conductor tracks 140 crossing in a diamond-like pattern. In another exemplary embodiment, the conductor tracks can also intersect in a square arrangement, for example, or be aligned parallel to one another.

In one exemplary embodiment, the first conductor tracks 135 are each connected to the first electrical contact 120 , which in this exemplary embodiment is formed as a first contact strip along a first edge region 145 of the textile fabric 100 . The second conductor tracks 140 are connected to the second electrical contact 130 , which is formed congruently to the first electrical contact 120 as a second contact strip along a second edge region 150 of the textile fabric 100 , merely by way of example. In this exemplary embodiment, the first electrical contact 120 represents the first contact strip applied to a first section 155 of the first surface electrode 115 already arranged on the textile 105, and the second electrical contact 130 represents, merely by way of example, the contact strip applied to a second section 160 of the first surface electrode 115 already arranged on the textile 105 arranged second surface electrode 125 applied second contact strips. In another exemplary embodiment, the first electrical contact 120 and the second electrical contact 130 can also have been applied to the textile at the same time as the electrode arrangement.

The shape of the contacts 120, 130 is only shown as an example. The shape and arrangement of the contacts 120, 130 can also be designed differently, and the first contact 120 and/or the second contact 130 can also comprise a plurality of individual contacts. During operation of the textile fabric 100, the contacts 120, 130 can be connected via electrical lines to a voltage source which can provide the voltage difference required to generate the non-thermal plasma to the electrode arrangement.

2 shows a schematic representation of a textile fabric 100 according to an embodiment. The textile fabric 100 shown here corresponds to or is similar to the textile fabric described in the previous figure, with the difference that the textile fabric 100 in this exemplary embodiment is in the form of yard goods. In this case, the electrode arrangement 110 is arranged only by way of example over approximately 70% of a width 200 of the textile fabric 100 . In another version For example, the arrangement of the electrode arrangement can vary along the width of the textile fabric, for example it can be arranged over at least 50% of the width, over at least 80% of the width or over the entire width. In this exemplary embodiment, the electrode arrangement 110 has a diamond pattern that continues endlessly both in the width 200, which can also be referred to as the x-direction, and in a length 205 of the textile fabric 100, which can also be referred to as the y-direction leaves. It is thus possible to produce a textile semi-finished product in the form of rolled goods and thus also in large quantities at very low prices. With the help of this semi-finished product, patterns can then be cut out and covers for a wide variety of geometries can be produced without the need for an individually manufactured electrode design each time.

3 shows a schematic cross-sectional view of a textile fabric 100 according to an embodiment. The textile fabric 100 shown here corresponds or is similar to the textile fabric described in the previous figures, with the difference that in this exemplary embodiment a separating layer 300 is arranged between the first surface electrode 115 and the second surface electrode 125 . According to one exemplary embodiment, the separating layer 300 is formed from an electrically insulating material, as a result of which the first surface electrode 115 is electrically insulated from the second surface electrode 125 by the separating layer 300 . Alternatively or additionally, the electrical conductors forming the first surface electrode 115 and/or the second surface electrode 125 are surrounded by an electrically insulating sheathing. If the electrical conductors of the first surface electrode 115 and the second surface electrode 125 are surrounded by an electrically insulating sheath, the separating layer 300 can be formed from an electrically conductive material or, for example, material that becomes electrically conductive when it absorbs moisture.

By way of example only, the separating layer 300 is indicated by the in 1 described textile formed. In another embodiment, the separating layer can also be formed with an additional material, for example in the form of a very thin knitted spacer fabric, in which conductive structures are knitted into both surfaces and spaced apart from one another by the structure of the knitted spacer fabric, i.e. by the pile threads, and accordingly insulated are.

Alternatively, a fabric can be printed on both sides with conductive material, or two conductive textiles can be laminated to one another with non-conductive adhesive film or the like.

In one exemplary embodiment, the separating layer 300 is designed to be compressible in order to optionally form a capacitive area sensor together with the electrode arrangement 110 . In this way, for example, a compressive force acting on the textile fabric 100 can be detected. In order to use the electrode arrangement 110 as a capacitive area sensor, suitable measuring signals can be applied to the contacts 120, 130 in accordance with known capacitively acting sensors.

In one exemplary embodiment, the first surface electrode 115 optionally has an additional contact 305 for enabling a current to flow through the first surface electrode 115 . The flow of current through the first surface electrode 115 that can be generated in this way makes it possible to heat the textile fabric 100 . As a result, the textile fabric 100 is in addition to the in 1 The disinfecting function described can also be used as surface heating. If, in addition or as an alternative, the second surface electrode 125 is used as a heating element, the second surface electrode 125 is equipped with a corresponding additional contact in a corresponding manner.

In other words, in addition to generating the non-thermal plasma, the same conductor geometry can also be used as a capacitive surface sensor and as surface heating. This means that additional functionalities can be included with the same semi-finished product through appropriate control and energy supply. This means that the textile fabric 100 can only be implemented as an example with the adaptation of a corresponding control or evaluation electronics with seat heating, seat occupancy detection and self-cleaning function. The property of the capacitive area sensor can also be used, for example, to make the plasma generation activatable only when a seat covered with the textile fabric 100 is unoccupied.

4 shows a schematic representation of an embodiment of a seat 400 with a seat cover 405 with a textile fabric 100, as was described in the previous figures. The textile fabric is completely integrated into the seat cover 405 purely by way of example. Depending on the exemplary embodiment, the textile fabric 100 is hidden under a top layer of the seat cover 405 or forms a top layer or the entire fabric of the seat cover 405 . The electrode arrangement is optionally designed at the same time as a capacitive area sensor in order to detect whether the seat 400 is occupied.

5 shows a schematic representation of an exemplary embodiment of a seat 400 with a textile fabric formed as a seat insert 100. The textile fabric 100 shown here corresponds or is similar to that in the previous ones 1 until 3 described textile fabric. The textile fabric 100 in this exemplary embodiment is shaped and designed as a seat insert, which can also be referred to as an inlay, in order to be arranged between the seat 400 and a seat cover or simply under an upper cover on a foam padding of the seat 400, for example. In this exemplary embodiment, an interface 502 for an energy supply or a control of the electrode arrangement of the textile fabric 100 is arranged between a seat surface 505 and a backrest 510 .

6 FIG. 12 shows a schematic representation of a vehicle 600 with a seat 400. The seat 400 shown here corresponds or is similar to that in the previous ones 4 and 5 described seat and is covered with a seat cover 405, with the in the previous 1 3 described textile fabric 100 is designed for generating non-thermal plasma.

In one exemplary embodiment, the vehicle 600 optionally includes a control device 605 which is designed to cause the first and the second voltage potential to be applied to the electrode arrangement of the textile fabric 100 in response to a disinfection signal 610 . For this purpose, for example, an electrical connection is closed between the electrode arrangement and an energy supply device, or the control device 605 is designed to provide the corresponding voltage potentials to the electrode arrangement itself. The voltage potentials applied to the electrode assembly cause the non-thermal plasma used to disinfect the seat cover 405 to be generated.

In this exemplary embodiment, the disinfection signal 610 is provided by a sensor device 615, which is designed to detect contamination of the seat cover 405 and to provide the disinfection signal 610 in response to the detection. In another exemplary embodiment, the disinfection signal can also be provided manually by a user of the vehicle 600, for example by means of a remote control, in order to save personnel costs in particular with so-called free floating fleets, or automatically when leaving the vehicle 600.

In one exemplary embodiment, the control device 605 is designed to only make the plasma generation activatable in response to the disinfection signal 610 if an occupancy signal 620 provided using the electrode arrangement represents an unoccupied seat 400 . For this purpose, the electrode arrangement is additionally designed as a capacitive area sensor, for example.

7 FIG. 7 shows a flowchart of a method 700 for producing a textile fabric according to an exemplary embodiment. The method 700 has a step 705 of providing an electrode arrangement and a textile and a step 710 of assembling the electrode arrangement with the textile to produce the textile fabric. In this case, a diamond-shaped pattern made of conductive material is applied to the textile, merely by way of example, by means of a printing process. In another exemplary embodiment, the electrode arrangement can also be applied by coating or embroidering, or integrated directly into the textile or introduced into it, for example by working, weaving or knitting. For example, crossing conductor tracks can be introduced into the textile by means of insulated yarns, wires, strands, etc., whereby, for example, all conductors running in the same direction represent one electrode and all these crossing conductors represent the other electrode. In this case, however, the contacting becomes more complex, since the conductors should only be stripped in the area of the contact points. In one embodiment, the method also includes an additional step 715 of applying a contact strip. In this step 715 of application, the electrical contacting takes place via conductive contact strips applied to two opposite sides of the textile fabric, which are applied to the required locations by gluing following the assembly. In another exemplary embodiment, the contacts can also be applied, for example, by laminating on conductive textile strips or embroidering on conductor tracks. The contact to the energy source or control electronics can be made, for example, via a joining and contacting technique.

Thus, in step 710, for example, an electrode arrangement that has already been shaped or only segments of the electrode arrangement and a textile that has already been shaped can be joined together. Alternatively, for example, segments of the electrode arrangement and segments of the textile can be joined together, for example woven, as a result of which the textile with an integrated electrode arrangement is formed. Depending on the shape of the electrode arrangement, the contacts can, for example, be joined to the textile together with the surface electrodes or as part of the surface electrodes in step 710 or be supplemented in the separate step 715 .
