Description

technical area

The The present invention relates to electrically conductive yarns, their use and process for their preparation.

It are some methods of making 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 fabrics are often problematic to manufacture on the loom and feature due to the exposed wires over one only limited 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 methods in which centrally guided metal wires easy or double-wound textile. Because in these yarns essentially the wire's tear strength determined, are usually relatively thick wires with diameters greater than 0.1 mm inserted. Such yarns are relatively stiff and therefore for textile Applications unusable.

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 be stretched to a significant extent, since the conductive threads either tear 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 the invention

Here implements the invention. The invention as characterized in the claims The object of the invention is to provide yarns that are electric conductivity have, but in mutual contact no electrical Line between the individual yarns or different yarn sections cause.

These The object is achieved by the Yarn according to claim 1 solved. Further advantageous details, aspects and embodiments of the present invention Invention will be apparent from the dependent claims, the Description, figures and examples.

The according to the invention electrically conductive yarn includes at least one flexible core thread, at least one the electrically conductive thread wound on the core thread and at least one, Outside around with the electrically conductive Thread wound core thread wound electrically non-conductive multifilament yarn. The electrically non-conductive Multifilament yarn is at least 70 times per meter of yarn with an electrically conductive thread wound core thread wound and consists of at least 5 individual filaments. The individual filaments have a diameter of at least 0.1 .mu.m.

multifilament yarns lie flat on the winding of a core the soul, so they have the same raw yarn outside diameter one in comparison lead to a monofilament of equal thickness significantly higher area coverage. Relax touching Single yarns are due to the covering nature of the outer wrap with an electrically non-conductive multifilament yarn no electrical Contact each other.

The according to the invention electrically conductive textile Combination yarn has a flexible core, which is not rubber-elastic Properties, a first, inner enclosure and, at least partially over the first serving lying second envelope, the first serving at least partially made of electrically conductive materials and the second serving from an electrically non-conductive textile multifilament yarn consists.

In addition to electrically conductive Wrap the yarn according to the invention thus comprises a further outer, non-conductive Wrap of at least one multifilament yarn. This electric insulating wrap can take on different functions and leads thereby to a whole set of improved characteristics of the yarn according to the invention. Examples include: electrical insulation, mechanical Abrasion protection, improving the processability of the yarn on fast-running Machines, mechanical stabilization of the inside conductive thread, Color, shine, appearance, feel, feel, compensation of internal torsional stress of the yarn after wrapping in one direction, sweat transport, Humidity regulation, temperature compensation.

The both servings can also not with mere Fingers are moved on the core. The combination yarn loses its electrical conductivity also after implementation of at least 5 standard washes according to DIN EN 6330 at 40 ° C Not. It is washable, resistant across from chemical cleaning and opposite Abrasion.

Becomes one consisting of at least 5 individual filaments not electrically conductive Multifilament yarn per meter of yarn at least 70 times around with a electrically conductive Thread wound wound core thread and show the individual filaments of Multifilamentgarns a diameter of at least 0.1 microns, so covers the non-conductive Multifilament yarn the conductive Components of the electrically conductive yarn so far from that it at a pressure-free contact between two single yarns to none electric line between these single yarns comes.

A adequate insulating outer cladding and more of the mentioned cheap Properties can by varying the parameters "Number the filaments of the electrically nonconducting multifilament yarn "," number of convolutions of the electrically non-conductive Multifilament yarn per meter of yarn "and" diameter of the individual filaments of electrically non-conductive Multifilament yarn "achieved become. In the context of the present invention, the skilled person can this match three parameters. Proves, for example in the production of a particular yarn the use of a Multifilament yarn with a rather small number of individual filaments as advantageous, so can the resulting lower coverage the conductive one Ingredients by a higher Umwindezahl and / or by a larger diameter of the individual filaments be compensated.

Basically results improved coverage with increasing number of individual filaments, with increasing number of turns and increasing diameter the individual filaments. On the other hand, this parameter is technical Set limits. So the multifilament yarn can technically a maximum of 1500 times per meter of yarn are wound around the core thread. Too big On the other hand, the number of individual filaments causes the individual filaments when winding no longer flat lay next to each other around the wound thread but at least partially over each other to come to rest. In addition to the unnecessarily increased material consumption point such yarns in the finishing poorer properties on.

The said parameters will therefore be coordinated with one another by the person skilled in the art in such a way that sufficient insulating coverage is achieved with the most economical possible use of materials and at the same time good textile properties. The yarns according to the invention cause at 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 According to the present invention, the individual filaments of the electric non-conductive Multifilamentgarns a diameter between 10 .mu.m and 100 .mu.m, between 20 μm and 60 μm or between 30 μm and 50 μm.

Also preferred embodiments are according to those the electrically non-conductive multifilament yarn at least 80 times per meter of yarn, 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 already mentioned can these parameters are advantageously matched to one another by the skilled person become.

Depending on the application are suitable for the electrically non-conductive winding of various materials. Examples include: nylon, polyester, viscose, polyamide, Linen, wool, silk, cotton, polypropylene, kevlar in various embodiments as well as mixed yarns of all kinds.

Prefers If the textile core thread of the yarns according to the invention consists of non-rubber-elastic, but flexible materials. Such threads are commercially available yarns between 20 dtex to 3000 dtex. They consist of natural or synthetic fibers, Mono- or multifilament constructions, are textured or smooth and have tear strengths of more than 0.5N.

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

Of the flexible core of the composite yarn is with an electrically conductive inner Envelope equipped. The used electrically conductive thread must be so twisted around the core that stretching the entire yarn unit 5% no plastic deformation or fracture inducing mechanical Load of the electrically conductive Thread causes.

The Extensibility of the entire electrically conductive yarn is thus through limited to the core thread. To fulfill this feature are Core thread, conductive Wrap and non-conductive outer wrap in terms of material and in terms of the number of wraps around the core thread appropriate to each other Voted. In addition, some more advantageous to the expert adapted in the field of yarn production known parameters. Furthermore the different thread materials have different coefficients of friction which requires a different amount of force, around the individual threads to shift against each other. For one skilled in the yarn making art Selection is not a problem.

Of the Core thread can be in one for the particular application can be used appropriate form. exemplary be some variants called: monofilament, multifilament and textured Types. If necessary, can also several threads be used in parallel or twisted in the core. It can be similar or different threads be used side by side.

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

When electrically conductive Threads are suitable especially metallic wires, Wire twisted or braided, conductive coated synthetic fibers, Metallic staple yarns and conductive filled synthetic fibers and conductive polymers. The electrically conductive Thread can be used single or multiple, sorted or mixed become.

Monofilament metal wires used for wrapping are suitable for numerous embodiments of the invention, particularly in a thickness range between 0.01 mm and 0.12 mm, preferably between 0.02 and 0.06 mm, particularly preferably between 0.03 and 0.05 mm. Although in principle many metals and alloys, which may additionally be coated or pickled, are suitable for producing yarns of the invention with wire, copper wires, silver-coated copper wires, silver wires, stainless steel wires and brass wires are particularly preferred due to technical and economic factors. The use of coated or coated wire types improves the corrosion resistance and washability of the yarns of the invention. Such yarns are not only good Washable, they even resist chemical cleaning.

Next monofilament metal wires Multifilament stainless steel yarns are perfectly suited for production the yarns of the invention. Typically, the thickness of a single stainless steel filament is moving in the range between 0.002 mm and 0.02 mm. The number of included Single filaments is between 10 and 1000.

For many Applications are the use of silver-coated synthetic Yarns for electrically conductive Wrap around the flexible core. Particularly suitable are wash-resistant, silver-coated Nylon yarns for producing the yarns of the invention. The market offers both monofilament and multifilament yarns. With multifilament yarns as a turn around higher core area coverage compared to monofilament fibers same yarn diameter can be achieved.

The Production of the yarns according to the invention can basically take place in all known to those skilled species. Preferably, the central flexible thread biased on a drafting system. The preloaded Core thread is guided by a rotating hollow spindle. On the hollow spindle sits the yarn package with the Umwindefaden. The wrapping thread is from the uniformly withdrawn core thread taken along, so that the wrapping thread in the form of a helix around the Core thread is wound.

By the winding of the core thread with another thread creates inner torsional that lead to, that the yarn in the unloaded state, so when unwinding the coil twisted around itself. Become two threads around the core thread tortuous, this gives rise to the possibility of this internal torsional forces to eliminate. One speaks in this case of a "Ausbalanzieren" of the yarn the second thread namely wound in the opposite direction to the first thread around the core thread, so give torsional forces in opposite directions. Material and number of turns can now be matched by simple experiments so that the amounts the torsional forces approximately are equal and have a resulting torsional force of nearly Zero results. As a result, it is ensured that the yarn barely or not at all when unloaded twisted itself.

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

The present invention also encompasses the use of the yarns of the invention, Fabrics and textiles for data transmission and for powering electrical and electronic components. Besides this, the use of the yarns according to the invention is also possible and tissue as electrically conductive materials similar to one Ribbon cable or a spatially resolved controllable two-dimensional Matrix different electrical signals without significant mutual Can convey influence side by side.

Further can inventive yarns or fabric and textiles made of it for shielding electromagnetic Fields or to dissipate static charges.

The The present invention also includes the use of the yarns of the invention as electrical heating conductors and the fabric made therefrom elastic, electrically heatable fabrics and textiles.

The In addition, the present invention also includes the use of the yarns according to the invention as Sensor, preferably as a humidity sensor or strain sensor.

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 With 22 Single filaments shown. 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 illustrate also the use of multifilament yarns as an outer, non-conductive 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.
