Definitions

  • the present invention relates to an electrically conductive yarn comprising one or more bundles of metal fibres and to its various uses.
  • Yarns comprising one or more bundles of metal fibres are known. Such yarns are e.g. applied in vehicle seat heating systems or heatable textiles. In these applications, the yarns are used as an electrical resistance and provided, in use, with an electric current to obtain the required heating effect. In many of the applications of such yarns, the yarns are subjected to different stress and/or strain conditions. In particular, the yarns may be repeatedly loaded under tensile and/or bending or torsion stresses, e.g. when applied in a car seat heating. When repeatedly subjected to such stresses, metal fibres of the yarn may break, eventually resulting in the failure of the yarn. As a result, the yarn may no longer provide its function as a heating element in e.g. a car seat heating.
  • this object is achieved by a yarn for car seat heating comprising one or more bundles, each bundle comprising at least thirty metal fibres, said metal fibres comprising stainless steel and a metal which is electrically more conductive than stainless steel, such as e.g. copper or a copper alloy, said yarn comprising a predetermined number of torsions per meter, characterized in that said predetermined number of torsions per meter is smaller than 80 per meter and larger than 10 per meter.
  • Examples of a metal “which is electrically more conductive than stainless steel” are e.g. copper, aluminium, nickel, silver, gold or any alloy thereof.
  • the bundles comprise and at least 30 metal fibers.
  • all the fibers in the bundle are metal fibers.
  • all the fibers in the bundles are metal fibers comprising stainless steel and a metal which is electrically more conductive than stainless steel.
  • the metal fibres can be single drawn or bundle drawn.
  • a single drawn fibre the diameter reduction is done by means of a series of dies for one fibre.
  • For bundle drawn fibres the diameter reduction is done by means of a single series of dies for the whole bundle, as e.g. described in U.S. Pat. No. 3,379,000, U.S. Pat. No. 3,394,213, U.S. Pat. No. 2,050,298 or U.S. Pat. No. 3,277,564.
  • the cross section of a fiber has usually a pentagonal or hexagonal shape as is shown in FIG. 2 of U.S. Pat. No.
  • the number of torsions per meter may vary from 10 per meter until 80 per meter, e.g. from 20 per meter until 70 per meter, e.g. from 30 per meter until 60 per meter.
  • the term “number of torsions” must be understood to be the amount of twist or torsion used to obtain the electrically conductive yarn, or stated otherwise, the number of turns about the axis of the yarn. In case only one bundle is present in the yarn, the number of torsions is the amount of torsion applied on this individual bundle. In case two or more bundles are present in the yarn, the number of torsions is the amount of twist used to combine the bundles into the yarn.
  • a yarn according to the present invention encompasses the following examples:
  • the individual bundles have no torsions on their own.
  • the fibres as applied in yarns according to the present invention comprise multiple layers of metal and at least they comprise both stainless steel and a metal which is electrically more conductive than stainless steel, such as e.g. copper or copper alloy.
  • a metal which is electrically more conductive than stainless steel such as e.g. copper or copper alloy.
  • the equivalent diameter of the individual metal fibres is typically smaller than 50 ⁇ m, e.g. smaller than 40 ⁇ m, e.g. smaller than 20 ⁇ m.
  • the fibre diameter is typically greater than 1 ⁇ m, e.g. greater than 2 ⁇ m, e.g. greater than 6 ⁇ m. It has been observed that a reduced fibre diameter also has a positive effect on the flexlife.
  • the metal fiber yarn can further be coated with a suitable coating, preferably PVC, PVA, PTFE (polytetrafluoroethylene, also called Teflon) FEP (copolymers of tetrafluoromethylene and hexafluoropropylene), MFA (perfluoroalkoxy polymer) or polyurethane lacquer.
  • a suitable coating preferably PVC, PVA, PTFE (polytetrafluoroethylene, also called Teflon) FEP (copolymers of tetrafluoromethylene and hexafluoropropylene), MFA (perfluoroalkoxy polymer) or polyurethane lacquer.
  • a yarn according to the invention is advantageously used in car seat heating, but also in textile products in general or for heating applications in general.
  • FIG. 1 schematically shows a cross-sectional view of a yarn according to the present invention
  • FIGS. 2 a and 2 b schematically illustrate two possible ways of twisting multiple bundles about one another to obtain a yarn according to the present invention
  • FIG. 3 schematically illustrates the flexlife of a yarn as a function of the number of torsions per meter
  • FIG. 4 schematically illustrates the application of a yarn according to the present invention as a heating element for a car seat.
  • Yarns according to the present invention comprise one or more bundles of metal fibres, each bundle comprising at least 30 metal fibres.
  • FIG. 1 schematically depicts a cross-sectional view of a yarn 100 according to the present invention.
  • the yarn 100 comprises three bundles 110 , 120 and 130 each comprising more than 30 metal fibres 140 .
  • metal is to be understood as encompassing both metals and metal alloys (such as stainless steel) or compositions.
  • the metal fibres as applied in the present invention may comprise a stainless steel core enclosed by copper or a copper alloy.
  • the metal fibres as applied in a yarn according to the present invention may have a copper core surrounded by a stainless steel mantle.
  • Such fibres provide improved electrical properties combined with the corrosion and oxidation resistance of stainless steel.
  • Said stainless steel is preferable chosen out of AISI 300 series such as AISI 302, 304, 316 or 316L, or AISI 400 series such as AISI 430, AISI 625 or AISI 904.
  • the fibres forming the bundles may either be bundle-drawn fibres or single drawn fibres.
  • the metal fibres as applied in the yarns according to the present invention preferably have an equivalent diameter being less than 50 micrometer, but more than 0.5 micrometer, preferably between 1 micrometer and 35 micrometer, yet preferably between 7 and 21 micrometer.
  • the equivalent diameter of a fibre is to be understood as the diameter of an imaginary circle, having the same area as the cross section of the fibre.
  • the bundles of fibres as applied in the yarns according to the present invention are obtained from a bundle-drawing process.
  • the latter process may advantageously be applied as it enables the manufacturing of thinner fibres compared to a single-drawing process.
  • the bundle-drawing process can be considered a more economical process as it results in a plurality of fibres being obtained at the same time.
  • bundle drawing of metal fibres reference can be made to U.S. Pat. No. 3,394,213, U.S. Pat. No. 2,050,298 or U.S. Pat. No. 3,277,564.
  • the yarns according to the present invention may advantageously be applied to obtain a textile product, e.g. a braided, woven, knotted or knitted textile product.
  • the metal fibres as applied in the yarns according to the present invention may comprise a core of a material having a higher electric conductivity compared to steel or steel alloys.
  • Preferred materials for forming such a core are copper or copper alloys.
  • bundles of such materials may equally be obtained by grouping a plurality of single-drawn wires or filaments, or, preferably, as in the present invention, using a bundle-drawing process, as e.g. described in JP-A-5-177243 and WO-A-2006/120045 obtaining metal fibres with multiple layers.
  • a bundle of metal fibres having a copper or copper alloy core and a mantle of e.g. stainless steel can be obtained.
  • the stainless steel mantle may comprise AISI 316L steel or AISI 625 or AISI 904.
  • Said bundles may advantageously be applied in yarns according to the present invention for such applications where the electrical conductivity is important, such as electrical heating applications.
  • Such applications can e.g. include heatable textiles wherein the electrically conductive yarn functions as a resistive heating element.
  • Such textiles can e.g. be part of a heating device which is integrated in a car seat, usually between a foamed part of the seat and the seat upholstery.
  • a further application where the electrical conductivity is important and where the yarns according to the invention may advantageously be applied is the use as leadwire connecting different electronic devices to each other such as batteries, PCB's or monitoring devices.
  • FIGS. 2 a and 2 b Two options are illustrated in FIGS. 2 a and 2 b.
  • FIG. 2 a schematically depicts two bundles A and B and a reference line L on the outer surface of each bundle (if the bundle is untwisted, then the reference point is a fibre L the fibre being located on the circumference of the bundle).
  • One way of twisting the different bundles A and B is by bending the bundles about each other, substantially without applying any torsion on the individual bundles. As such, the twisting of the two or more bundles does not result in a (additional) torsion of the individual bundles.
  • reference line L or fibre L
  • This process is sometimes referred to as “cabling” and can be carried out by means of tubular twisting machines.
  • the bundles of the yarns can be twisted by applying a torsional force on the two or more bundles. By doing so, the individual bundles also have a torsion on their own, or get an additional torsion. This is illustrated on the right side of FIG. 2 b . This process is sometimes referred to as “bunching” and can be carried out by double-twisting machines.
  • FIG. 3 schematically indicates the flexlife FL as a function of the number of torsions per meter N.
  • an important flexlife improvement is obtained when the number of torsions per meter is kept below 80.
  • the flexlife can be increased even further.
  • a minimum number of approx. 10 torsions per meter should be observed.
  • a good compromise between an improved flexlife and avoiding the bundles from spreading too far apart is found when the number of torsions per meter is between 30 and 60.
  • FIG. 4 schematically shows a car seat 500 provided with a textile product 510 comprising yarns in accordance with the present invention as electrical electrodes 511 .
  • Carbon wires 512 may be coupled to an electric device (not shown) that is arranged to provide, in use, the required current to the textile product by means of two cables 513 , each being coupled to an electrode 511 to which the carbon wires 512 are coupled. This arrangement is called a parallel car seat heating element.
  • a serial car seat heating embodiment can be provided, where the yarns according to the present invention function as the heat resisting elements.
  • the following table 1 shows, as an example, the experimentally determined flexlife of the following yarns.
  • the yarns are indicated as:
  • c represents the number of fibres per bundle
  • d represents the number of torsions per meter.
  • the flexlife can be determined by subjecting a sample length of a yarn to a repeated bending over a bending radius of about 0.60 mm to 0.80 mm and under an axial load.
  • the bending degree in such a test is generally taken as 180°.
  • a micro-current is arranged to run through the yarn sample, the yarn sample forming part of an electrical circuit. Once all fibres of the sample are broken, the electric circuit is also broken and the counting of the number of bendings is stopped.
  • Flexlife must be compared for yarns having a same tex number (tex is being expressed in g/1000m).
  • tex is being expressed in g/1000m.
  • the flexfactor which is the ratio of the number of flex life cycles to the Tex of the yarn, is therefore an appropriate means for comparing the “flexlife” of a yarn.
