Heiztextil, its production process and its

use

description

The present invention relates to a heating textile for

Transfer of heat to an environment according to the preamble of claim 1. From the prior art known heating textiles, in addition to heating conductors also always Kontaktle oner, which the

allow electrical current flow to heat the heating conductors. For example, DE 101 12 405 A1 discloses a surface heating element with a textile base material. The contact conductors are glued in advance with a finished, textile base material. Only in a further, completely decoupled from this process step, the heating elements are fed separately. Consequently, there is a time-consuming and expensive to produce surface heating element. Another disadvantage is the numerous steps that are necessary during production. In addition, the splices also represent unwanted break points to which the contact closure breaks and the Function of the entire surface heating element can be significantly reduced.

In addition, the contact conductors are usually ironed or glued to a nonwoven, so as to be an unwanted

To avoid current flow in the sense of a short circuit.

In particular, ironed contact conductors have proven to be disadvantageous in practice, as in the course of time or with a corresponding bending of the heating textile in curved

Surfaces the ironed connection can break and the contact is no longer guaranteed. Similarly, it is also in the power supply terminals, which are glued to the finished Heiztextil, and thus provide a high target for corrosion and possible detachment.

It is therefore an object of the present invention to provide a

Provide Heiztextil, which is designed low maintenance and durable. Furthermore, it is also the task of

present invention, a uniform, reliable

To provide temperature output, overheating too

avoid and even be inexpensive to manufacture.

This object is achieved according to the features of patent claim 1.

The heating textile described here is formed of Stehfasersträngen and shot fiber strands, which form at least one fiber strand situation. To form on the one hand a stable and on the other hand a functional heating textile, Stehfaserstränge and / or Schussfaserstränge are themselves functionally trained. By functional is to be understood advantageously that the respective fiber strands have a certain property.

For example, the heating textile may have weft fiber strands which are designed to be electrically conductive.

Furthermore, the Heiztextil may have Stehfaserstränge, which heat up by electrical energy supply and can deliver this heat to the environment. Finally, the heating textile described here can continue

Have contacting, each of which form the positive pole and the negative pole. All of these fiber strands thus have a certain function, so that in the joint processing as a knitted fabric and / or scrim and / or knitted fabric results in a functional Heiztextil, which can deliver targeted heat to its environment.

The core idea of the present invention is that in addition to contacting, energy-emitting

Fiber strands and electrically conductive fiber strands continue, so in addition, at least one

Coupling fiber strand is provided at least to the contact closure of the energy-emitting fiber strands with the electrically conductive fiber strands and / or the contacting means with the electrically conductive fiber strands, wherein the electrically conductive fiber strands and / or the

Contacting agent and / or the energy-emitting

Fiber strands are formed as Ständerfaserstränge and / or shot fiber strands and the weinigstens one

Coupling fiber strand meshed directly or indirectly around the Stehfaserstränge and shot fiber strands and / or knitted and / or laid to connect these together.

All combination variants described here

Fiber strands with each other can be formed both directly and / or indirectly. Under direct is advantageous to understand the immediate coupling, in which the fiber strands to be coupled at least one common

Form contact surface with each other. Under indirect

Coupling is advantageous to understand the connection in which no direct common contact surface is formed between the fiber strands to be coupled. In the case of indirect coupling, for example, an additional material can be introduced between the fiber strands to be coupled so that they each form a common contact surface with the intermediate material. in the

In the simplest case, the coupling is formed at intersection points of the Stehfaserstränge with the weft fiber strands.

Under electrically conductive elements are advantageous

Fiber strands, nonwovens, flat textiles or film structures to understand, with particular advantage, the electrically conductive elements are designed as electrically conductive fiber strands or fiber bundles. Here, fiber bundles can be understood to mean a multiplicity of fiber strands which are parallel to one another, wound or in

can be arranged otherwise.

In addition to the electrically conductive elements, energy-emitting fiber strands and contacting means, the flexible heating textile described here additionally has at least one coupling fiber strand, advantageously several Coupling fiber strands on. The coupling fiber strands serve for the direct and / or indirect connection, that is to say coupling, of further fiber strands to be connected. For this purpose, the at least one, advantageously a plurality of coupling fiber strands, is introduced directly during the production of the heating textile. Depending on the embodiment, the coupling fiber strands may be acted upon, inserted or entangled. Regardless of the three types of processing described here, the introduction or processing of the coupling fiber strands means a fixation of the fiber strands to be joined together. Particularly advantageous is the work of

Coupling fiber strands shown, as this is particularly stable and strong mesh around the fiber strands to be coupled

be formed. In addition, the coupling fiber strands form with the fiber strands to be coupled, usually at their intersection points large contact surfaces. in the

In the simplest case, the coupling fiber rod meshes around the crossing points of the fiber strands to be joined and form only small free spaces, where no common

Contact surfaces present.

It has surprisingly been found, for the first time, that a large number of coupling fiber strands provide a particularly stable and reliable contact closure between the

energy-emitting fiber strands and the electric

conductive elements and / or between the

Contacting agents and the electrically conductive

Training elements. For this purpose, the advantageous several coupling fiber strands are mesh-like, so that they are the Stehfaserstränge and shot fiber strands at their

Connect crossing points directly and / or indirectly with each other. Firm connection here is to be understood as meaning that the advantageous multiple coupling fiber strands the

Intersecting points of standing fiber strands with weft fiber strands mesh-like manner and thus with the Stehfasersträngen and / or Schussfaserstränge, which are to be joined together form the largest possible, common contact surface, so that the contact closure is permanently ensured.

Under the greatest possible, common contact surface between coupling fiber strands and Stehfasersträngen and / or

Weft fiber strands are advantageously 25% to 80% of the

Scope of a single standing strand of fiber and / or

To understand shot fiber strand.

The standing fiber strands used here and / or

Weft fiber strands advantageously form a nearly round or completely round cross-section. Will now be

Coupling fiber strand around a crossing point of

Stehfaserstrang and shot fiber strand worked, so the corresponding coupling fiber strand meshes both strands and couples them.

Since the Heiztextil has numerous Stehfaserstränge and numerous shot fiber strands, which are all formed from each other and spaced apart, the Heiztextil described here is also referred to as Heiztextilgitterelement.

The leadership of the coupling fiber strands takes place in the simplest embodiment from bottom to top of the

Stehfaserstränge and / or shot fiber strands around. Thus it can be ensured that a particularly close and Fixed mesh training is possible and thus the

Free space between coupling fiber strand and standing strand of fiber and / or shot fiber strand is kept as low as possible. This is particularly advantageous if the flexible heating textile is coated after its completion in a possible process step. Due to the reduced clearances between coupling fiber strands and Stehfasersträngen and / or weft fiber strands, it is now possible for the first time to coat particularly efficiently, without resulting in the formation of impermeable structures. The mesh-like arrangement of the coupling fiber strands thus makes it possible for the first time to provide flexible heating textiles in the form of flexible grid elements for transferring heat to an environment, which can be coated particularly efficiently and which, moreover, retain their grid element character even after coating.

The flexible heating textile described here for the first time is designed as a grid element, for example as a scrim, knitted or knitted fabric, and has at least standing fiber strands and

Shot fiber strands on. The Stehfaserstränge are also known as 0 ° fiber strands, which extend in the longitudinal direction of the Heiztextils. Advantageously, the corresponds

Longitudinal direction of the Heiztextils at the same time the transport direction during the manufacturing process. The continue

provided fiber strands are also referred to as 90 ° - fiber strands and extend in the simplest case, transverse to the Stehfasersträngen.

For the first time, all functionalities which the heating textile described here can now be provided and configured in the form of fiber strands and / or fiber bundles. Under Fiber strands are advantageous to understand individual fibers and / or filaments, wherein a fiber strand has at least one fiber and / or a filament. Advantageously, a fiber strand but also as a multifilament and / or as

Multifiber be formed and as a single filament the

Characterization tdexlO f2-3 to have 96,000 tdex with 90,000 k. Possible fibers and / or filaments are natural materials, synthetic materials,

inorganic materials or organic materials or a mixture thereof conceivable.

Furthermore, it has surprisingly been found advantageous to form the electrically conductive elements as weft fiber strands. In the simplest case, the electrically conductive elements are introduced as 90 ° threads. This results in the simplest case tracks for the

electricity.

Furthermore, the energy-emitting fiber strands for heating the environment as Stehfaserstränge, also referred to as 0 ° - fiber strands may be formed. These extend in the longitudinal direction of the heating textile to be produced during its production process. The 0 ° fiber strands are advantageously arranged parallel to one another and spaced apart from one another. The same applies to the weft fiber strands, so that when they are arranged a lattice structure of the flexible heating textile is formed.

Furthermore, for example, the contacting means for forming at least one closed circuit may be arranged parallel to the energy-emitting fiber strands. For this purpose, the contacting agents are in two groups divided. A first group forms the plus pole and a second group forms the minus pole.

In the simplest case, energy-emitting fiber strands and contacting means form, as mutually spaced 0 ° fiber strands, a plane in which energy-emitting fiber strands and contacting means adjoin one another

are arranged.

Further advantageously, the contacting means are arranged in groups, for example in two groups. It is conceivable that at least one contacting means has at least one fiber and / or at least one filament. Fibers differ to filaments only in their

limited length.

The material of the contacting agents is therefore not limited to textile fibers, glass fibers, carbon fibers or the like, but also metal fibers can be used. Furthermore, nonwovens, conductive sheet-like textiles or even electrically conductive

Plastic films are used as contacting agents.

Now to an energy transfer, here in particular one

To ensure flow of current, the flexible heating textile described here still has coupling fiber strands. It has surprisingly been found that via these coupling fiber strands to form a contact closure of the associated further fiber strands, a particularly simple and cost-effective production of the flexible

Heating textile is made possible for the first time. The

Heating fabric grid element can heat efficiently and constantly deliver the environment without overheating itself. Here it is flexible and flexible.

In addition, a high heat resistance and a high

Thermal conductivity can be ensured, and permanently.

The above-mentioned predetermined breaking points from the state of

Techniques which are used by gluing or soldering in known heating textiles are not used in the present invention. The ones described here

Coupling fiber strands form an energetic coupling with the associated fiber strands, so that

For example, the heat generation and the power line is formed by the contact closure accordingly. For this purpose, the coupling fiber strands are mesh-like,

knitted or laid formed.

In the simplest case, the coupling fiber strands can be formed meshed with and / or around the electrically conductive elements, the energy-emitting fiber strands and / or the contacting means for the successful contact closure. In particular, forms of fringe stitches, jersey stitches, cloth stitches, satin stitches, atlas stitches, or open body stitches or velvet stitches have been found to be advantageous. With all the mesh forms listed here can be particularly solid, permanently stable and secure

Be trained contacts, while saving time and cost savings in production and

Maintenance.

In addition, it is also conceivable that the

Coupling fiber strands directly and / or indirectly to the Crossing points of the fiber strands to be joined in the form of fringe stitches, jersey stitches, satin stitches, atlas stitches, open body stitches, velvet meshes are meshed and / or twisted or twisted when the heating textile described here is designed as a scrim , Thus, the intersections between the Stehfasersträngen and shot fiber strands can be firmly connected together in one step during manufacture.

Under contact closure is advantageous to understand that the weft fiber strands with the Stehfasersträngen and vice versa at the respective intersection points through the surrounding mesh form a contact closure, so that, for example, the transmission of energy, advantageously electrically and / or in the form of heat, permanently enabled. In addition, the meshing causes additional stabilization of the flexible heating textile.

Of course, this is not limiting, so that other combinations of Stehfasersträngen and weft fiber strands are possible.

Furthermore, it is also conceivable that the functional fiber strands described here, such as energy-emitting fiber strands, electrically conductive elements and contacting means and / or coupling fiber strands cover the entire heating textile

span.

Further details emerge from the subclaims. In a further advantageous embodiment, it is conceivable for the heating textile to have, in addition to the functional fiber strands, additional support fiber strands, which serve as

Stehfaserstränge and / or are formed as a shot fiber strands. This is particularly advantageous if an excessively large free area would be arranged between the spaced-apart electrically conductive elements, so that the

Stability of the heating textile would be reduced. In this case, it has proved to be advantageous to introduce further support fiber strands as shot fiber strands. These stabilize the heating textile described here and can be made from the above

be formed materials mentioned.

Furthermore, the support fiber strands serve to form the flexibility of the heating textile described below

simultaneous mold preservation. Advantageously allow the

Support fiber strands bending and draping the Heiztextils depending on the particular application, for example, curved components. It is also conceivable that such support elements, as the support fiber strands may also be referred to, instead of or in addition to the fiber strands and auxiliary yarn form, which in the further processing for better connection with others

Materials used.

In a further advantageous embodiment, the Heiztextil is formed as a scrim, fabric or knit. As a particularly advantageous and easy to manufacture, the training has shown as a knit or as a clutch.

In particular, in the formation of the heating textile as knitted fabric, in which case the coupling fiber strands are formed as meshes which connect the further fiber strands with one another, For the first time, a heating textile can be provided which has a grid structure. At the same time, the lattice structure is made particularly strong and stable by the action of the coupling fiber strands. In addition, the meshes of the coupling fiber strands provide at least partial encasement of the fiber strands associated therewith, thus ensuring a relatively compact bond with little clearance between the individual coupling fiber strands and the associated further fiber strands. This allows for the first time after the possible coating method of

Heiztextils, for example, with a plastic, further ensuring the open grid structure and the

Reduction of coating material between

Coupling fiber strands and related others

Fiber strands. Thus, predetermined breaking points and excessive plastic coating surfaces between the individual

Fiber strands avoided. This requires a significant increase in the quality of the heating textile, which here for the first time

is described.

In a further advantageous embodiment is between contacting and electrically conductive

Fiber strands arranged at least one insulating element, wherein the contacting means are connected via the coupling fiber strands with the at least one insulating directly and / or indirectly or the contacting means on the

Coupling fiber strands on the at least one insulating directly and / or indirectly with the below the

Insulating arranged electrically conductive

Fiber strands are connected. The insulating element is advantageously used for decoupling between contacting means and electrically conductive elements in order to avoid a short circuit at their crossing points. Therefore, it is also important to form the coupling fiber strands from an electrically non-conductive material. In the simplest case, coupling fiber strands and

Insulating element may be formed from the same material.

The at least one insulating element has at least one, advantageously a plurality of insulating materials, which are not formed electrically conductive. Particularly advantageous materials for coupling fiber strands and / or insulating such as PES, other polymers such as

For example, polyethylene or polypropylene, natural fibers such as hemp, flax, kenaf and / or a mixture thereof.

In these electrically insulating materials, the

Processing of the insulating element in Heiztextil be carried out particularly easily. By inserting and arranging the at least one insulating exactly between

Contacting agents and electrically conductive fiber strands are successfully decoupled from each other. to

simplified fixing are the contacting means with the coupling fiber strands on the at least one

Insulating element fixed directly. Furthermore, it is also conceivable that the Ummaschung the contacting means by the at least one insulating element is carried out and the underneath

lying electrically conductive fiber strands are also ummascht. As a result, an even better fixation and stability is formed. The fixation is advantageously done by knitting, knitting or laying. This is the Insulating element advantageously flat,

For example, as a non-woven material or as

Plastic film.

In the simplest case, the fixation of the

Contacting means with the at least one insulating element via a meshing in the knitting process, knitting process or laying process during manufacture.

The at least one insulating element can, in one

Embodiment, formed continuously in the longitudinal direction of the heating textile.

However, this is not limiting, so that it is also conceivable that the at least one insulating element

only at and / or at the intersections of electrically conductive fiber strands and contacting agents

is arranged in sections. It always applies

ensure that the insulating element performs its function and unwanted short circuits or contacts between the contacting means and the electrically conductive fiber strands are avoided.

To be particularly advantageous, it has been found that the two groups of contacting agents, which advantageously the positive pole and the negative pole of the described here

Form heating fabric, are arranged close to each other.

Arranged close to one another is a distance to one another in the centimeter range, for example at a distance of 0.2 to 10 cm. It is possible by this close arrangement for the first time to tailor flexible heating textile individually in its surface size, without the heating function gets destroyed. From the prior art it is known that plus and minus pole in known heating textiles are each widely spaced from each other, are arranged on the outer edges. This limits the packaging of the

Heiztextils drastically and conditionally high

Production costs to individual Heiztextilgrößen

manufacture. This is achieved for the first time with the heating textile described here, in which positive pole and negative pole are arranged close to each other and at the same time decoupled from each other for the first time. The overhanging lateral surfaces of the

Heating textile can be assembled freely. It is

for example, conceivable that positive pole and negative pole are arranged in a left edge region of the heating textile. The remaining area of the heating textile is only through

energy-emitting fiber strands and electrically conductive

Fiber strands, optionally with support fiber strands

educated. Thus, the remaining, remaining area is freely configurable, since all three mentioned

Fiber strand types can be easily cut without the actual heating function is lost.

Furthermore, it is also conceivable to arrange positive pole and negative pole centrally in the middle, so that the laterally beyond projecting surfaces of the Heiztextils can be assembled accordingly on the left and right.

Alternatively, it would be conceivable on both edge regions of the

Heiztextils each provide a group of contacting. So a simple division between the

Groups take place and both Heiztextilteile would be full

functioning . In a further advantageous embodiment, the heating textile on at least a first recess, which is formed fiber strand free. This at least first recess is advantageously arranged between the positive pole and the negative pole, provided no insulating element is provided.

Advantageously, the recess can be seen as an alternative to the insulating element described above. The recess prevents a short circuit. Particularly advantageously, the recess interrupts the electrically conductive

Fiber strands between positive pole and negative pole. This is

necessary, since in the manufacturing process, the electrically conductive fiber strands throughout in the Heiztextil

are introduced. Therefore, the fiber strands would otherwise be in contact with both the positive pole and the negative pole at the same time. There would be a short circuit. To prevent this, the at least one first recess is provided. This can be particularly cheap and fast during the

Are applied manufacturing process.

In the simplest case, this is done by punching. Thus, all fiber strands used in the heating textile as

Standing fiber strands and weft fiber strands are provided, whereby the production is accelerated and at the same time costs are reduced.

Furthermore, it is conceivable that the heating textile has an additional, second recess for contacting the contacting means with the electrically conductive fiber strands. In this embodiment, an insulating member between the electrically conductive fiber strands and the

Provided contacting. The insulating element itself has this second recess, so that at this controlled, predetermined position of the recess form the contact means direct contact with the electrically conductive fiber strands. A permanent one

Connection is ensured by the close meshing of the electrically conductive fiber strands with the contacting means through the coupling fiber strands.

In a further advantageous embodiment, the Stehfaserstränge and shot fiber strands to each other at an angle of 30 ° - 150 °. As a result, a corresponding grid structure is formed, since advantageously also the

Stehfaserstränge and shot fiber strands to each other

Have spacing.

It has proved to be particularly advantageous for the

Fibers strands at a distance of 0.01 mm - 5 cm to each other to arrange. The standing fiber strands can

advantageously be presented with a fineness to a target between El and E50. Thus, the lattice structure with open through holes / openings, which by the spacing of the Ständerfaserstränge to the weft fiber strands and the Ständerfaserstränge with each other and the results

Weft fiber strands are formed with each other. This lattice structure is particularly advantageous if the heating textile is to be subsequently coated with a coating material, for example an aqueous plastic solution, since the plastic solution can drip off correspondingly in particular through the lattice structure and the lattice structure after the cured coating is retained. The

Lattice structure is advantageous for power dissipation and flexible embedding in possible materials. The

Lattice structure ensures that the one described here Heating textile can be embedded particularly well and firmly in other materials.

In a further advantageous embodiment, the energy-emitting fiber strands and / or the electrically conductive fiber strands and / or the support fiber strands and / or the contacting of electrically conductive, non-insulated materials such as metals or their compounds, alloys and their compounds, from organic materials such Carbon-containing

Materials, electrically conductive polymers, metallized fiber strands, or inorganic materials such as glass fibers and / or a mixture thereof formed. Both

energy-emitting fiber strands, it has proven to be advantageous that they have a high ohmic resistance

to generate an effective amount of heat. In the case of the current-supplying, ie electrically conductive fiber strands, materials such as, in particular, copper, stainless steel, copper alloys, gold, zinc or silver-coated copper have proved to be advantageous. In addition, are

carbonaceous materials, PTC yarns as conductive polymers and / or metallized textile yarns conceivable. The materials mentioned here can also be used as flat

Heiztextil be used knitted advantageous, it is always considered that the coupling fiber strands are not electrically conductive.

Furthermore, the Heiztextil described here characterized by the fact that it is to be operated in miniature protective voltage by high-impedance filaments and / or mains voltage. This is especially advantageous for overheating protection and also for power consumption. In a further advantageous embodiment, this is

Heating textile two-dimensional and / or three-dimensional

educated. This is advantageous, since in this way a high degree of flexibility is formed in the area of use of the heating textile.

The flat two-dimensional design is advantageous if the heating textile is to be inserted into thin components, where little material is required. Due to the design of the heating textile as a grid element can also thin

Material orders a high stability and installation safety are guaranteed.

The formation of a three-dimensional Heiztextil is particularly advantageous because this curved surfaces and

Structured structures and, for example, the use of seat cushions or mattress bases (mattresses and the like) forms additional applications. Under three-dimensionally, a multilayer heating textile with at least one cover surface and at least one base surface is advantageous

understand. Both surfaces are made of the same and / or

different material Stehfasersträngen and

Weft fiber strands formed, for example as a knitted fabric, scrim or knit.

Furthermore, both surfaces are spacers

firmly connected and spaced at the same time

from each other. Possible spacer elements may advantageously be pile threads which, for example, to the respective

Crossing points of standing fiber strands and

Weft fiber strands are arranged on each surface. The pile threads connect the two surfaces together. In addition, there are also entanglements, interweaving, forebodings,

Transfers and the like conceivable.

It has proven particularly advantageous in the three-dimensional design of the heating textile to integrate the heating textile described here in the cover surface and / or the base surface in the case of such a grid element designed as a heating textile. Consequently, the heating textile described here then forms directly the top surface and / or the base surface of the three-dimensional formation. This integration takes place already during production and can be implemented in a particularly simple and cost-effective manner. That's how it works

described Heiztextil the top surface and / or the

Form base of the multilayer heating textile.

Due to the advantageous embodiment of the spacer elements, for example, as a continuous spacer thread, is a

Formed a plurality of spacers. These can form, for example, a spring function by their training and thus assign the three-dimensional Heiztextil additional flexibility and damping function.

Furthermore, a corresponding material reinforcement or simply a spacer between base and top surface is also conceivable. To a textile heater in the

To work in three-dimensional Heiztextil, it is important to process the individual fiber strands, as described above, in the cover and / or the base. In addition to the knitting method, the laying method or the knitting method has proved to be particularly advantageous. Particularly advantageously, the three-dimensional Heiztextil in its unchanged initial form, ie without any external application of force, a total material thickness of 0.5 - 700 mm. Particularly advantageous has a

Material thickness in the range of 1 - 50 mm proved. Particularly advantageous is the material thickness, ie the distance between the base and the top surface to each other by 8 mm. With this particular material thickness sufficient flexibility of the heating textile while maintaining the stability of the active compounds, laying joints or knitted connections is given for the first time. Furthermore, it is advantageous to arrange the Verschlaufungspunkte, ie the compounds of base and top surface congruent with each other.

As a result, in particular in the case of a crescent-shaped course of the spacer elements, a high restoring force is effected, which after a force application allows a return to the desired shape, that is to say the starting position which is not acted upon by force.

In addition to the crescent-shaped course is also conceivable, a

Zigzag shape or a sawtooth shape of the course of the

Provide spacer elements between the base and the top surface. Furthermore, interruptions are themselves formed in a hexagonal shape. The combination of hexagonal arrangement and hexagonal formation of the

Interruptions provides the greatest possible load capacity and compressive rigidity, as well as shear stability over the entire surface of the upper deck surface.

Particularly advantageous are six mutually hexagonally arranged, hexagonal interruptions in one

Surface area provided by a 1 - 3 cm ² , the Dimensions of the interruptions are formed in the range of 1 - 4 mm in width and 1 - 10 mm in length.

Of course, this is not limiting, so it is also conceivable to provide significantly larger dimensions of the interruptions, especially in green roofs, so that the interruptions in a surface area of 25 - 50 cm ² dimensions in the range of 5 - 50 mm in width and 10 - 80 mm in length.

Of course, the interruptions may also have the same extensions in their width as in their length. Again, the above dimensions apply. The hexagonal training is of course not limiting, so that it is also possible, the interruptions polygonal such as round,

rectangular, oval, diamond-shaped, square, triangular or in any other polygonal shape.

In an alternative, advantageous embodiment of the

Heating textile, the coupling fiber strands are replaced in part by the energy-emitting fiber strands, the original energy-emitting fiber strands are now replaced by support fiber strands. At the same time, the energy-emitting fiber strands form stitches, so that the weft fiber strands are meshed or meshed with the standing fiber strands in such a way that standing and weft fiber strands are closely connected at their points of intersection.

Due to the mesh formation of the energy-emitting fiber strands, more contact points are formed between them and the electrically conductive fiber strands than is the case with a layer of weft and standing fiber strands. As a result, the electrical contact resistance between energy-emitting fiber strands and electrically conductive fiber strands is significantly reduced, which leads to a higher overall efficiency of the heating textile.

Furthermore, in addition to the heating textile, as described above, the present invention relates to the method for

Production of this heating textile. The method points

at least the following steps:

Providing at least one standing fiber strand feed for feeding standing fiber strands,

Providing at least one shot fiber strand feed for feeding a plurality of spaced apart fiber strands,

- coupling standing fiber strands and weft fiber strands together by simultaneously acting or knitting or laying at least one coupling fiber strand

Formation of mesh-like connections.

The method described here describes for the first time the production of a technical heating textile in the form of a grid element where, as described above, weft fiber strands and stalk fiber strands to each other or weft strands and Stehfaserstränge are arranged spaced from each other and thus forms a lattice structure with continuous openings. This technical Heiztextilgitter, as the Heiztextil described above can also be called, is formed by the fact that the Stehfaserstränge with the

Weft fiber strands or vice versa knitted, knitted or be placed by these advantageous to their

Crossing points with each other through wenigstnes one

Be wrapped or meshed Kopplungsfaserstrang.

In particular, the stable active compound is characterized by the

Introduction of at least one coupling fiber strand, advantageously of a plurality of coupling fiber strands, which are used bundled / processed formed. Advantageously, the coupling fiber bundle per standing fiber row is guided in each case via a perforated needle. The crossing points of Stehfasersträngen and weft fiber strands are thereby sequentially meshed and thus fixed to each other. Particularly advantageously, the Ummaschung controlled by a predeterminable thread train, so that it is also ensured that shot fiber strands and Stehfaserstränge be arranged together, so as to first aufzuspannen the Heiztextil in its surface.

In the particular case, the heating textile is produced in such a way that the weft fiber strands can be formed as support fiber strands and / or electrically conductive fiber strands. The Stehfaserstränge can be formed here as energy-emitting fiber strands and as a contacting.

Furthermore, it is conceivable that the method described here comprises a further method step, which is carried out between step b) and c). This further

Process step, as in a further advantageous

Embodiment described is that between the Stehfasersträngen at least one insulating element is supplied. This is particularly advantageous because the feeding of the at least one insulating element during the

Manufacturing process, so to speak at the same time with the downstream Verwirk performed. For this purpose, the at least one insulating element is advantageously formed like a flat surface and is, for example, via a

Conveyor supplied accordingly. Consequently, the at least one insulating element below the Stehfaserstränge and above the weft fiber strands to the processing process.

With the feeding of the at least one insulating element, the Ummaschung is then performed in a next step. The at least one coupling fiber strand, which is advantageous as a coupling fiber bundle with a plurality of fiber strands

is formed, is gripped by a guided from bottom to top needle and acted accordingly. Thus, can

be sure that the Ummaschung of

Stehfasersträngen and Schussfasersträngen with the

intervening at least one insulating permanently and safely implemented.

Particularly advantageously, the hole needle is passed from bottom to top through the working plane to the

to grab at least one coupling fiber strand. In this example, the standing fiber strand feed is also above and the shot fiber strand feed is located below the supplied at least one insulating element.

In an alternative advantageous method, the coupling fiber strands are partially replaced by the energy-donating fiber strands, with the original energy replacing fiber strands replaced by strands of support fiber become. In this case, the Stehfaserstränge and the Schussfaserstränge be intermeshed or intermeshed at the intersection points, so that standing and Schussfaserstränge are closely connected at their intersection points. The energy-giving fiber strands are each guided via a perforated needle, so that the Ummaschung the floor and

Weft fiber strands controlled with a predeterminable thread train takes place.

Furthermore, the present method is characterized in that the knitted or laid or knitted

Heating textile is pulled flat and / or steep in the optional step of the manufacturing process. The fabric take-off of the heating textile, which subsequently also further

Can undergo treatment steps, for example a

Coating, is crucial for the mesh strength. For example, a steep fabric removal directly after the manufacturing process, especially if this as

Furthermore, the present invention also claims a system for producing a flexible heating textile, as described above, and / or a system for carrying out the

Production process also as described above. For this purpose, the system has at least the following components: a) a standing fiber strand feed for feeding the standing fiber strands above or on a second side of the working plane,

b) a Schussfaserstrangvorbringer for arranging the

Weft fiber strands, at least one slide element and at least one knock-off element, wherein

Schussfaserstrangvorbringer, slide element and

Abschlagselement are arranged below or on a first side of a working plane,

c) at least one needle for working or laying or

Knitting at least one coupling fiber strand, more preferably coupling fiber bundles, in the form of stitches around the one to be joined together

Fiber strands.

The system described here for the first time has been specially developed for the production of technical textiles, in particular of the functional, technical heating textile described here. It is now possible to technical

Textiles about the knitting process or knitting process or

To produce a fast and high quality clutch process while saving time. A processing of the technical fiber strands, as described here, for example, glass fiber strands,

electrically conductive fiber strands and the like, could not currently be produced on known textile systems. These could u.a. do not hold the necessary fiber tension because conventional fibers such as cotton have completely different properties, such as a PTC yarn.

In a further advantageous embodiment, the system has at least one feeding device for feeding at least one insulating element between weft fiber strands and Stehfaserstränge, wherein at least one free end of the Standerfaserstrangführung at least one projection for holding down the insulating element during the

Manufacturing process is arranged.

This system is a special one

Running the system using the above

described insulating element. By the hereby first described construction of the system for the production of

Heiztextils it is possible for the first time in a compact

Process within the processing level to be able to train reliable and fast product production. In particular, it is advantageous in this case if at least one projection, advantageously in the form of a nose, for holding down the at least one insulation element is provided on at least one end of the standing fiber strand guide. This projection also keeps the at least one insulation element substantially flat during the manufacturing process, while thus the coupling fiber strands, weft strands and

Stehfaserstränge be meshed through the at least one insulating element therethrough.

This advantageously forms a common

Contact surface between weft fiber strands and insulating element. By holding down the at least one

Insulating element in the working plane and thus during the manufacturing process, especially during the kneading process, it can be ensured that the Stehfaserstränge arranged above it and the underlying Schussfaserstränge particularly safe and without large

Force can be meshed with each other. A unwanted wave formation of the insulating is thus prevented.

In a further advantageous embodiment of the system, the same also has at least one needle under point c) for knitting or laying or knitting at least one energy-emitting fiber strand, advantageously energy-releasing fiber bundles, in the form of loops around the fiber strands to be joined together.

This is the first time possible with the machine described here or with the system described here. Thus, summarized a particularly effective system

be provided, which the processing time for

Production of a corresponding Heiztextils clearly

reduced and allows a customizable assembly. With the system described here, it is possible for the first time to produce and implement any size relationships in the surface, as well as in three-dimensional space one above the other, in a compact production method, in particular the mode of action.

Finally, the present invention also relates to

Use of the heating textile described in

Automotive interiors for heating interior trim, vehicle seats, in greenhouses for direct temperature control of plant pots, in the outdoor area for temperature control of plants growing above, as a seat cushion, mattress or mats, for example in the form of

Mattress components, sports mat components,

Yoga mat ingredients or relaxation mat ingredients. Furthermore, the present invention also relates to the use of the above-described heating textile in the construction sector

Heating of building parts such as ceilings and / or walls and / or as a textile reinforcement element. In this case, the flexible Heiztextil the function of a heating mat

have, serve for deicing or even for

Temperature control of molds or components are used. Particularly advantageous may be a three-dimensional

Grid element with integrated Heiztextil additionally be provided as a reinforcing element in concrete components. This is clearly an advantage, for example, when de-icing bridges.

By flexible is to be understood here that the Heiztextil can be deflected from its original flat, horizontal plane, without the functionality or quality can be reduced. In particular, this is to be understood as deflections of more than 5 ° from the horizontal.

Advantages and expediencies are in the following

1 shows a schematic plan view of a first embodiment of a heating textile 1, wherein L of the longitudinal direction, ie the transport direction, and A of

Working width corresponds. In addition, it should be pointed out that all views shown in FIGS. 1 to 3 represent only the smallest repetition unit in the longitudinal direction. Advantageous is a large number of these units in

Longitudinal direction L of the heating textile 1 is provided. In

Longitudinal direction L, the standing fiber strands are introduced, while the shot fiber strands are introduced in the direction of the working width A.

The heating textile 1 is formed of 0 ° fiber strands extending in the longitudinal direction L and 90 ° fiber strands extending in the working width direction A.

The weft fiber strands extend in the simplest case, as shown here, with angle to the Stehfasersträngen. They can serve to support the heating textile 1 and / or to supply the electrical energy via appropriate

electrically conductive fiber strands 6a, 6b. In this example, the electrically conductive fiber strands 6a form the negative pole. This will be one or more

electrically conductive fiber strands 6a or

Fiber bundles formed. These are to each other

formed spaced. The electrically conductive

Fiber strands 6b form the positive pole. This may also be formed of one or more fiber strands or fiber bundles, which are also spaced from each other.

Furthermore, two groups of contacting means 10a,

10b provided.

For fixing Stehfasersträngen and shot fiber strands together coupling fiber strands 8 are provided. These can, as shown here, advantageous as Ummaschung in

Mesh form selected from the group Franze, jersey, cloth, satin, velvet, satin and open twill selected and trained. However, this is not limiting, so the fixation also be formed over wrap, loop or the like.

Furthermore, at least one insulating element 12 is arranged. This is arranged between the electrically conductive fiber strands 6a, 6b and the contacting means 10b and decouples them from each other. The contacting agents

10a, 10b are advantageously formed as Kontaktierungsfaserstränge. The contacting means 10b are also via the coupling fiber strands 8 with the insulating member 12th

connected, for example, meshed or knitted.

In addition, the electrically conductive fiber strands 6a, 6b arranged below the insulating element 12 can also be detected by the lap, so that the insulating element 12 can be firmly and non-slippable between the two

decoupling fiber strands 10a, lOv and 6a, 6b is arranged. This successfully prevents a short circuit from occurring.

To short circuit between positive pole and negative pole

avoid, a first fiber strand-free recess 14 is disposed at the level of the electrically conductive fiber strands 6b. At the same time, this recess 14 is located between the two groups of Kontaktierungsfasersträngen 10 a, 10 b. In the simplest case, the recess 14 is formed as a punched-out. In addition, the embodiment of the

Heiztextils 1 yet another recess 16. This is below the contacting fiber strand group 10b, in the

Insulating element 12 at the height of the electrically conductive

Fiber strands 6b arranged. This second recess 16 is also formed as a punched hole. It serves for the contacting of contacting means 10b with the electrical conductive fiber strands 6b. However, this is done only in the size and dimension of the recess 16. The electrically conductive fiber strands 6a remain

still isolated.

In the simplest case, the contacting means 10a, 10b may also be formed as strands and / or bands, which group a plurality of fiber strands. The connection to a

Power source occurs after exposure of a few

Centimeters, which are sufficient for a commercial

Plug to install. Among others is also possible the

Contact by splicing, soldering or gluing with a power cable.

Furthermore, the heating textile 1 energy-emitting

Fiber strands 2, which are introduced spaced apart as Stehfaserstränge.

2 shows a further embodiment of the heating textile 1. The same reference numerals as before correspond to the same components and will not be explained again here.

In contrast to FIG. 1, the heating textile 1 in FIG. 2 shows an enlarged insulating element 12, which is flat,

extending continuously below both contacting agent groups 10a, 10b. In this embodiment is to the

Recess 16 of FIG 1, yet another recess 16 is formed. This is formed at the level of the electrically conductive fiber strands 6a below the contacting means 10a in the insulating member 12. This arrangement of the two recesses 16 prevents unwanted

Short circuit. Both in FIG 1 and in FIG 2 are the

Contacting means 10a, 10b arranged close to each other. This has the advantage that the

Contacting means 10a, 10b are fixed in their position. The Heiztextil of Stehfasersträngen and

Weft fiber strands, which in the plan view right next to the contacting means 10b arbitrarily continue

extends is perfect in its working width A.

to produce and assemble individually. Consequently, the adjacent arrangement of the contacting means 10a, 10b offers a significantly higher degree of flexibility

Heiztextilgeometrie, as it is even possible in the prior art.

In FIG. 3, a third exemplary embodiment of a heating textile 1 is shown. Again, the same components as before correspond to the same reference numerals and will not be explained again.

This Heiztextil 1 has Stehfaserstränge and

Shot fiber strands on. The contacting means 10a, 10b are widely spaced in this embodiment

from each other, arranged opposite each other,

Advantageously, and / or in the respective edge regions of the heating textile 1. This embodiment is formed insulating element free. In order to avoid a short circuit, this heating textile 1 has two fiber-strand-free recesses 14. Both recesses 14 in each case interrupt the electrically conductive fiber strands 6a, 6b.

FIG. 4 shows the side view of FIG. 1 (top), FIG. 2 (center) and FIG. 3 (bottom). Here it is evident that the insulating elements 12 are positioned differently until completely omitted. In addition, the

Contacting means 10a, 10b arranged at different distances from each other. Furthermore, here are the knitted

and / or knitted and / or laid stitches of the at least one coupling fiber strand 8. It is

It can be seen that the stitches embrace both standing fiber strands and weft strands at their intersection points and thus fix them. If an insulating 12 is provided, it can also be seen that the mesh through the

Insulating element 12 pass through, so that the

Insulating element 12 between the Stehfasersträngen 2 and

Weft fiber strands 4 is processed.

In particular, when Ummaschung the crossing points of only Stehfasersträngen 2 and shot fiber strands 4, ie without Isolierlement 12, the narrow mesh is visible around the respective intersection point. Through this

snugly arranging the mesh of the mesh of a coupling fiber strand 8, virtually any clearance between the fiber strand and mesh is avoided. This is particularly effective when the technical textile Gitterlement so produced in retrospect with plastic as

Corrosion protection is coated. The coating can be done very effectively by the close stitch formation. An excessive amount of coating material in the

Free space is avoided, which significantly increases the processability and longevity of the technical heating textile. Unintentional sealant stresses and fractures are also avoided. In FIG 5, a three-dimensional textile 20 is shown, which as a top surface 44 and / or as a base 46 with

Spacer fiber strands 40 has integrated at least one described here Heiztextil 1. The same reference numerals as heretofore also correspond to the same components and are not explained again. As a result, for the first time a three-dimensional technical textile 20 with heating function is formed. This can be used, for example, for road building for deicing

Bridges, heating elements with textile probation, seat cushions, lying mat or mat, for example: mattresses / sports mat, yoga or relaxation mat, for direct temperature control of

Plants can be used in planters or in the ground or as a reinforcing element in building construction or civil engineering. The spacer fiber strands 40 are to be understood as spacer elements and may be formed, for example, as pile threads, as described above.

FIG. 6 shows a schematic side view of a system S which is needed to produce the heating textile 1. The system S has in particular a

Shot fiber strand feed (not shown), which introduces the weft fiber strands. In this case, electrically conductive fiber strands 6a, 6b or also support fiber strands 4 can be understood as weft fiber strands.

Above the weft fiber strands is at least one

Stehfaserstrangzuführung 22 arranged. This leads the

Stehfaserstränge the working plane B to. In this

Embodiment, the contacting means 10a, 10b and the energy-emitting fiber strands 2 on the

Stehfaserzuführung the processing level supplied. Furthermore, above the processing plane B are several

Hole needles 24 are arranged, which provide the Kopplungsfaserstränge 8.

Below the processing plane B, where the Ummaschung or knitting or laying or knitting takes place, needle 26, tee 28 and slide member 30 are arranged. The needle 26 is first from bottom to top, through the

Machining level B passed through, so that the needle 26 above the working plane B fed

Coupling fiber strands 8 can grab. Subsequently, the needle 26 is guided back down through the working plane B, where it is then abgemascht on the slider element 28.

Optionally, in this embodiment also the

at least one insulating element 12 introduced. The feed takes place just below the Stehfaserstranglage and above the Schussfaserstranglage. The insulating element 12 is thus between weft fiber strands and Stehfasersträngen

arranged. In the simplest case, the at least one insulating element 12 via a conveyor 32 to the

Processing process supplied. For this purpose, the conveying device may, for example, have a plurality of deflection rollers whose conveying tension is adjustable. This ensures that the insulating element in matching speed to the

Processing process is supplied. Tensions or

Wave formation of the insulating 12 is thus prevented.

At the end of the processing or manufacturing process, the generated Heiztextil is deducted. This can now be done flat as shown in FIG 6, for example in one Angle of 5 to 30 ° with respect to the horizontal working plane B in this embodiment.

In FIG 7 again the same structure is shown as in FIG 6. Same reference numerals correspond here again

same components. However, in Figure 7, the deduction of the Heiztextils 1. This is much steeper, for example in a range of 35 to 75 ° relative to the horizontal plane B. This is achieved in particular in an applied knitting process that the formed mesh of Kopplungsfaserstränge particularly be pulled tightly around the fiber strands to be joined.

FIG. 8 furthermore shows a schematic side view of the system S. Again, like reference numerals refer to like components, as previously explained. The difference to FIG. 1 is that here a three-dimensional textile 20 is produced. There are thus introduced several layers 34 of weft fiber strands, which then, as stated above, according mesh and with the

Knitted fiber strands 8 knitted or knitted or laid. The thickness, ie the thickness of the three-dimensional textile 20, is arbitrary.

FIG. 9 shows a further schematic view of a system S by means of which a further embodiment of the heating textile 1 described here can be produced. The already explained components are in this

Embodiment fiber chips 36 below the

Feeding fiber strands supplied. These are positioned by means of a fibrous chip retaining element 38. In the simplest Case, the fibrous chip holding member 38 may be formed as hold-down and controls the fiber chips 36 controlled, for example, flat, the processing plane B. As a fiber schnitzel come both natural and

synthetic fibrous pulps such as fiber reinforced plastics, which are used, for example, for vehicle handling, wind power, aircraft and shipbuilding, or the like, in

Consider.

Finally, FIG. 10 shows a further schematic view of the system S with which a further alternative

Embodiment of the heating textile 1 is implemented. Here, the working plane B is tilted by 90 °, so that the

actual knitting process or knitting process or laying process in the vertical direction takes place. This differs from the above examples, where editing is done in a horizontal orientation.

In the cross-section shown here of a double-walled knitting machine with 90 ° weft insertion, the heating textile 1 is produced with the following special features. The

Stehfaserstrangzuführung 22 can here as laying bar and with Stehfaserstrangzuführung (similar to FIG.6 - 9)

be formed. With it, the energy-emitting fiber strands 2 and / or the coupling fiber strands 8

brought in. The thread feed to the stitch formation, which connects the textile together, in particular the

Contacting means 10a, 10b, are fixed to the electrically conductive fiber strands 6a, 6b and / or the

Support fiber strands 4 contacted. For mesh formation, the coupling fiber strands 8 are worked with the perforated needle 24. It should be emphasized that up to 75 mm ² contacting means 10a, 10b to 15 mm width by Mehrfacheinzug simultaneously with a single feed

energy-emitting fiber strands 2 are processed.

The insulating member 12 with variably introduced recesses 14 or 16, which are punched out in the simplest case and used for contacting, is about

Conveyor 32 is supplied. The feeding takes place via individual, product-dependent strips, which can be arranged on a shaft with coils.

The electrically conductive fiber strands 6a, 6b, if necessary in alternation, to the support fiber strands 4, with 90 ° to

Needle needle 24 supplied. In knitting machines and / or

For jig machines, the weft insertion can deviate +/- 60 ° from 90 °.

The energy-emitting fiber strands 2 are with the

Stehfaserstrangzuführung 22 fed. At the locations with the contacting means 10a, 10b, a multi-feed occurs in the yarn feeders in order to achieve a higher square (E3-E44). These are arranged directly in front of the needle bar. In the Ständerfaserstrangzuführung 22 can by a

Leg bar, similar to FIG. 6-9 pictured, the

Contacting means 10a, 10b in parallel with the

energy-giving fiber strands 2 are drawn in a barre. The energy-emitting fiber strands 2 can also be supplied to the processing process additionally or simultaneously via the guide rail 24. The spacer fiber strands 40 are meshed with the textile surfaces in the knitting process. The Stehfaserstränge each form a textile surface, in which the

Spacer fiber strands are eingemascht.

Although the invention is illustrated and described in detail by the advantageous embodiments described herein, the invention is not limited to

Examples have been limited and other variations can be deduced therefrom by those skilled in the art without departing from the scope of the invention. In particular, the present invention is not limited to the following combination of features but other obvious combinations and sub-combinations of the disclosed features may be formed for those skilled in the art.
