Description

Technical area

The The present invention relates to electrically conductive yarns.

State of the art

It Some methods of making are more electrically conductive Yarns known. So z. B. for dissipation of electrostatic charge for a long time metal wires or wire mesh or metallized yarns incorporated directly into tissue. These tissues are often problematic to manufacture on the loom and dispose of due to the open lying wires over a limited only textile look and / or a metallic handle.

Further Methods are known for the production of so-called staple yarns. Essentially, short textile fibers are used together with short ones and very fine metal fibers spun into a yarn. Depending on the metal content These yarns are more or less textile or metallic Properties. Stacking yarns with good electrical conductivity have a metallic look and feel.

Known are also processes in which centrally guided metal wires be wound simply or double textile. Because in these yarns essentially the wire determines the tear strength, are usually relatively thick wires with diameters greater than 0.1 mm inserted. Such yarns are proportionate stiff and therefore unusable for textile applications.

The EP 250 260 B1 describes how thin wires in the core of a wound yarn can be used by the winding of parallel guided wire and textile thread. In this arrangement, the central textile thread provides tear strength, while the parallel running thin wire causes the electrical conductivity of the yarn. However, such yarns are not particularly elastic and not kink resistant.

In the CH 690 686 A5 the production of a composite yarn of textile Lunte and monofilament metal thread is described. During the yarn spinning process on a ring spinning machine, the fuse is fed centrally to a coated metal wire. In the thermal treatment following the spinning process, the melting coating bonds the central wire to the spun textile cover. These yarns have no good stretchability and are not kink-resistant.

None The yarns described above can be used without loss of electrical Conductivity can be stretched to a significant extent, since either tear the conductive threads or deform plastically.

The US 5,881,547 teaches the fabrication of a high tensile, electrically conductive yarn for use in fencing apparel. This yarn consists of an electrically non-conductive core thread and a double, criss-cross wound with stainless steel wire. It is very stiff due to the large diameter of the stainless steel wires used in the range between 0.6 mm and 1.2 mm and has little textile character.

In the DE 103 42 787 electrically conductive combination yarns are described, which have an elastic extensibility of at least 15% of their length due to their elastic core yarn. Due to their elastic properties such yarns are only partially suitable for processing on high-speed machines of the textile industry. In particular, the use as sewing or embroidery thread is possible only to a very limited extent.

In the US 4,776,160 a yarn construction is described in which a wire is essentially wound around a core thread. Such yarns are already stretchable and kink-resistant to some extent without loss of electrical conductivity, but still have a marked tendency to short-circuit with easy contact of the yarns with each other and abrasion sensitivity when processing on high-speed machines.

In the in the US Pat. No. 5,927,060 The yarn described is a textile core yarn wound with two to four filaments, wherein at least one of the wrapping yarns consists of wire. The relatively low Umwindefrequenz of 200 to 600 turns per meter of yarn leads to a low extensibility of the combination yarn until it comes to the breaking of the sheathing wire. This yarn construction suffers like that in the US 4,776,160 revealed yarn under short circuits with loose contact of the yarns with each other and a low abrasion resistance.

Presentation of the invention

Here implements the invention. The invention as defined in the claims the object of the invention is to provide yarns have the electrical conductivity, but at mutual Contact no electrical wire between the individual yarns or cause different yarn sections.

This object is achieved by the yarn according to claim 1. Further advantage Details, aspects and embodiments of the present invention will become apparent from the dependent claims, the description, the figures and the examples.

The inventive electrically conductive yarn includes at least one flexible core thread, at least one the core thread wound electrically conductive thread and at least one outside with the electrically conductive one Thread wound core thread spiral electrically nonconductive Multifilament yarn. The electrically non-conductive multifilament yarn is at least 70 times per meter of yarn with an electric thread conductive thread wound core thread wound and persists from at least 5 individual filaments. The individual filaments have one Diameter of at least 0.1 microns.

multifilament yarns lie flat on the winding of a core on the soul, so that they have the same raw yarn outside diameter one significantly higher compared to an equally strong monofilament Effect area coverage. Loosely touching Single yarns represent due to the covering nature of the outer Do not wrap around with an electrically non-conductive multifilament yarn electrical contact with each other.

The inventive electrically conductive textile Combination yarn has a flexible core, which is not rubber-elastic Features, a first, inner cladding and one, at least partially over the first envelope lying second enclosure, wherein the first enclosure at least partially made of electrically conductive materials and the second serving of one does not exist electrically consists of conductive textile multifilament yarn.

additionally for electrically conductive winding comprises the inventive So yarn another outer, non-conductive wrap from at least one multifilament yarn. This electrically insulating Wrap around can take over and perform various functions thereby to a whole set of improved characteristics of the yarn according to the invention. Examples include: Electrical insulation, mechanical abrasion protection, improvement the processability of the yarn on high-speed machines, mechanical stabilization of the internal conductive Yarn, color, shine, look, feel, feel, inner balance Torsion tension of the yarn after wrapping in one direction, welding transport, Humidity regulation, temperature compensation.

The In addition, both sheathings can not be combined with mere Fingers are moved on the core. The combination yarn loses its electrical conductivity even after implementation of at least 5 standard washes according to DIN EN 6330 at 40 ° C not. It is washable, resistant to chemical Cleaning and abrasion.

Becomes one consisting of at least 5 individual filaments not electrically conductive multifilament yarn per meter of yarn at least 70 times around the core thread wound with an electrically conductive thread wound and have the individual filaments of the multifilament yarn one Diameter of at least 0.1 microns, so does not cover conductive multifilament yarn, the conductive components of the electrically conductive yarn from so far that it at an unpressurized contact between two single yarns to any electrical Lead between these single yarns comes.

A sufficient insulating outer cladding and other of the mentioned favorable properties by varying the parameters "number of individual filaments of the electric Nonconductive multifilament yarn "," Number of convolutions of the electrically non-conductive multifilament yarn per meter Yarn "and" diameter of the individual filaments of the electrically not conductive multifilament yarn. "In the frame In the present invention, those skilled in the art can use these three parameters match up. Proves, for example, in the production of a particular yarn using a multifilament yarn a rather small number of individual filaments as advantageous, so the resulting lower coverage of the conductive Components by a higher Umwindezahl and / or by a larger diameter of the individual filaments be compensated.

in principle results in an improved coverage with increasing number Single filaments, with increasing number of turns and rising Diameter of the individual filaments. On the other hand, this parameter set technical limits. So the multifilament yarn can technically conditionally wound a maximum of 1500 times per meter of yarn around the core thread become. Too large a number of individual filaments causes on the other hand, that the individual filaments in the winding not lay more flat next to each other around the wound thread but at least partially come to lie one above the other. In addition to the unnecessarily increased material consumption have such yarns in the subsequent processing worse properties on.

The mentioned parameters are therefore coordinated by the expert be that sufficient insulating coverage at the most economical Material use and at the same time good textile properties is achieved. The yarns of the invention cause mutual Contact especially in the low voltage range no short circuits.

Prefers has the electrically non-conductive multifilament yarn at least 7, at least 10, at least 13, at least 16 or at least 24 individual filaments on.

According to others preferred embodiments of the present invention own the individual filaments of the electrically non-conductive Multifilament yarn has a diameter between 10 μm and 100 μm, between 20 μm and 60 μm or between 30 μm and 50 μm.

Also Preferred are embodiments according to which the electrically non-conductive multifilament yarn per meter Yarn at least 80 times, at least 300 times, at least 500 times, at least 700 times, at least 900 times or at least 1100 times wound around the core thread.

As These parameters can already be mentioned by the person skilled in the art be matched in an advantageous manner to each other.

Dependent from the application are not suitable for the electrically conductive wrapping of various materials. Exemplary called: nylon, polyester, viscose, polyamide, linen, wool, silk, Cotton, polypropylene, kevlar in the various embodiments as well as mixed yarns of all kinds.

Prefers is the textile core thread of the invention Yarns made of rubber-elastic but flexible materials. such Threads are commercially available yarns between 20 dtex up to 3000 dtex. They consist of natural or synthetic fibers, mono- or multifilament constructions, are textured or smooth and have tear strengths greater than 0.5N.

Appropriate Composite yarns with flexible core, electrically conductive inner covering and electrically insulating outer cladding can therefore without loss of electrical conductivity be stressed with at least 2 N in the longitudinal direction. You can miss it without loss of conductivity subjected to significant tensile stresses at least for a short time. The textile core thread largely takes over the tensile load and thus relieves the electrically conductive winding.

Of the flexible core of the composite yarn is with an electrically conductive equipped with inner wrap. The used electrically conductive Thread must be so wound around the core that stretching the entire Yarn unit 5% no plastic deformation or a fracture inducing mechanical load of the electrically conductive thread caused.

The Extensibility of the entire electrically conductive yarn is so limited by the core thread. To fulfill this property, are core thread, conductive wrap and non-conductive outer Handling in terms of material and in terms of number the wraps around the core thread appropriately to each other Voted. In addition, some more advantageous to the expert adapted in the field of yarn production known parameters. In addition, the different thread materials have different Friction coefficient on, causing a different force is required to the individual threads against each other to move. For the expert in the field of yarn production such selection does not pose a problem.

Of the Core thread can be suitable for the respective application Form are used. By way of example, some variants may be mentioned: Monofilament, multifilament and textured types. If necessary, can also several threads used in parallel or twisted in the core become. It can be similar or different threads be used side by side.

Of the flexible core can also be used multiple times with conductive threads be wounded. These conductive wraps can also applied in different winding directions and optionally by Interlayers be separated from each other.

When electrically conductive threads are particularly suitable metallic wires, wires or braids, conductive Coated synthetic fibers, staple yarns with metal content and conductive filled synthetic fibers and conductive polymers. The electrically conductive thread can be single or multiple, sorted or mixed.

to Wrap used monofilament metal wires are for numerous embodiments of the invention especially in one Thickness range between 0.01 mm and 0.12 mm, preferably between 0.02 and 0.06 mm, more preferably between 0.03 and 0.05 mm. Although in principle numerous metals and alloys, the additionally coated or stained, for producing yarns according to the invention with wire are due to technical and economic factors Copper wires, silver-coated copper wires, silver wires, Stainless steel wires and brass wires are particularly preferred. Improved the use of coated or painted wire types the corrosion resistance and washability of the invention Yarns. Such yarns are not only washable well, they resist rather, even a dry cleaning.

In addition to monofilament metal wires are suitable Multifilament stainless steel yarns very well for the production of the yarns of the invention. Typically, the thickness of a single stainless steel filament ranges between 0.002 mm and 0.02 mm. The number of individual filaments is between 10 and 1000.

For Numerous applications offer the use of silver-coated synthetic yarns for electrically conductive wrapping of the flexible core. Particularly suitable are wash-resistant, silver-coated Nylon yarns for the production of the invention Yarns. The market offers both monofilament and multifilament yarns at. With multifilament yarns as a wrap can be compared to monofilament fibers higher area coverage of the core can be achieved with the same yarn diameter.

The Production of the yarns according to the invention can in principle be done in any known to those skilled species, such as by wrapping techniques, Umwirbeltechniken or by twisting. Prefers The central flexible thread is pretensioned on a drafting system. The prestressed core thread is guided by a rotating hollow spindle. On the hollow spindle, the yarn package sits with the Umwindefaden. Of the Umwindefaden is subtracted from the even Threaded core, so that the wrapping thread in the form of a helix is wound around the core thread.

By the winding of the core thread with another thread creates inner Torsional forces that cause the Yarn in the unloaded state, so when unwinding from the coil, twisted around itself. Become two threads around the core thread twisted, this gives rise to the possibility of this inner To eliminate torsional forces. One speaks in this case of a "balancing" of the yarn, becomes the second thread namely in the opposite direction to the first thread around the core thread twisted, torsion forces result in opposite directions Directions. Material and number of turns can now be matched by simple experiments so that the amounts of torsional forces about are equal and have a resulting torsional force of nearly Zero results. As a result, it is guaranteed that the Yarn in the unloaded state hardly or not at all twisted around itself.

According to one preferred embodiment of the present invention So are the electrically conductive thread and the electric Non-conductive multifilament yarn in opposite directions around the flexible Wound core thread. So if the electrically conductive thread for example wound in the S direction around the flexible core thread is present, the multifilament yarn is in the Z direction to the flexible Wound core thread. It is therefore a crosswise winding. The present invention thus provides yarns, which are essentially free of internal torsional stresses and can therefore be processed without problems.

The present invention also provides textile structures such as fabrics, knits, Stitches, knits or nonwoven fabrics are available at least one inventive electrically conductive Include yarn. Preferably, warp and weft comprise these textile Each structure at least one invention Yarn.

The said textile structures can, for example, by Laminating on other fabrics, knits, leather, artificial leather or polymers are applied.

The Yarns, fabrics and textiles according to the invention can be used for data transmission and power supply electrical or electronic components are used. Besides can the yarns of the invention and Tissues are also used as electrically conductive materials, which similar to a ribbon cable or a spatially resolved controllable two-dimensional matrix different electrical Signals without significant mutual influence next to each other can transport. The invention Yarns, fabrics and textiles are therefore used for transmission of electrical signals, in particular the transmission of analog and / or digital signals.

Further can yarns of the invention or from it manufactured fabrics and textiles as a shielding element for shielding electromagnetic fields, as an electrical fuse or as an antistatic one Means are used to dissipate static charges.

The Yarns according to the invention can also be used as electrical heating conductors and as sensors, preferably as humidity sensors or strain sensors are used. The yarns of the invention manufactured fabrics can also be used as elastic, electrically heatable fabrics and textiles are used. In the event of of electrically heatable fabrics is a heat generation with the help of electricity.

The Yarns according to the invention are largely resistant to abrasion and can without restriction on sewing / embroidery machines or processed on knitting machines or looms.

Ways to execute the invention

How out 1 can be seen, the yarn of the invention comprises a textile core thread 1 , an electrically conductive thread 2 and an electrically nonconductive multifilament yarn 3 , The core thread 1 is made of non-rubbery but flexible materials. The flexible core 1 of the composite yarn is with an electrically conductive inner wrap 2 fitted. The electrically non-conductive multifilament yarn 3 is on the outside around the wound with the electrically conductive thread core thread 1 wound.

In 2 is an electrically conductive multifilament yarn 4 presented with 22 individual filaments. The parallel arrangement of the individual filaments of the electrically conductive multifilament yarn causes a significant increase in the area covered by the conductive filaments compared to the incorporation of a single filament. With multifilament yarns as a wrap, it is thus possible to achieve higher area coverage of the core with the same yarn diameter compared to monofilament fibers. Such yarns are particularly well suited for shielding electromagnetic fields. Very good properties in this context have the illustrated multifilament stainless steel yarns 4 on.

The 1 and 2 also illustrate the use of multifilament yarns as an outer, nonconducting wrap 3 , Multifilament yarns lie flat on the core when they are wound around a core, so that they produce a significantly higher area coverage in comparison with an equally strong monofilament with the same raw yarn outside diameter. This causes an electrically insulating effect.

Example 1:

One Thread made of textured polyester with 334 dtex and 96 individual filaments (Monofilament × 4) is biased on a yarn wrapper. The polyester thread is passed through a hollow spindle. These Hollow spindle carries a yarn spindle, from above Head a 0.041 mm thick, hard-silvered copper wire through the Polyester thread is peeled off. The simply wrapped with wire polyester is guided by a second hollow spindle. This hollow spindle wears a commercial polyester yarn with 167 dtex and 30 individual filaments. The outer polyester yarn is wound in opposite directions to the wire around the core. The machine parameters are selected to produce a well-balanced yarn, that is as free as possible from internal torsional stresses. The outer Polyester yarn is wound around the core 950 times per meter of yarn; the inner wire is wound around the core 1100 times per meter of yarn. Of the inside wire is approximately complete of the outer yarn covered so that the yarn over textile look and feel features. The yarn has excellent electrical conductivity and over a tensile strength of about 42 N. On a common Spool wound up, there is no electrical short circuit within the yarn windings, which are checked by resistance measurements can. The combination yarn loses its electrical conductivity not even after performing at least 5 standard washes according to DIN EN 6330.

Example 2:

A textured polyester yarn of 334 dtex and 96 single filaments (monofilament × 4) is biased on a yarn rewinder. The polyester thread is passed through a hollow spindle. This hollow spindle carries a conical yarn spindle, from which a 0.07 mm thick, hard-silver-plated copper wire is pulled through the polyester yarn over the head. The simply wrapped with wire polyester is passed through a second hollow spindle. This hollow spindle carries a commercial polyester yarn with 167 dtex and 30 individual filaments. The outer polyester yarn is wound around the core in opposition to the wire. The machine parameters are selected to produce a balanced yarn that is as free as possible from internal torsional stresses. The outer polyester yarn is wound around the core 1100 times per meter of yarn; the inner wire is wound around the core 950 times per meter of yarn. The inner wire is almost completely covered by the outer yarn, so that the yarn has textile look and feel. The yarn has excellent electrical conductivity and a tensile strength of about 42 N. wound on a conventional yarn spool there is no electrical short circuit inside half of the yarn windings, which can be checked by resistance measurements. The combination yarn does not lose its electrical conductivity even after performing at least 5 standard washes according to DIN EN 6330.

Example 3:

The yarn produced according to Example 2 is periodically a (see 3 ) as warp thread 5 incorporated into a fabric. Also at regular intervals b (see 3 ) becomes the same yarn as weft 6 incorporated into the tissue. Both warp and weft threads can be grouped 7 be used. Such a group of warp threads is in the 3 with the reference number 7 Mistake.

Example 4:

A fabric produced according to example 3 is present, for example, in a width of 1500 mm, the dimensions being a = 125 mm and b = 8 mm, and in each case 5 individual combination yarns from example 2 grouped are used as warp threads. From this tissue, a strip is separated in a width of about 310 mm. From the strip, a piece about 500 mm (4 × 125 mm) long piece is separated. The outer groups of warp threads 7 are severed so that a parallel connection of each 6 Weft threads results. The electrical contact between the warp and weft threads is at the in 4 positions shown 9 made by impregnation with a conductive adhesive or conductive ink. At the positions shown 10 the electrical contact is made to a 12 V DC power source. The textile shows a resistance of 4 ohms between the terminals. At 12 V supply voltage results in an electrical power of 36 W, which corresponds to a specific power of 24 mW / cm ² . The surface temperatures are about 40 ° C.
