Definitions

  • the invention relates to a woven or knitted band that comprises a lat eral direction and a longitudinal direction, and the structure of the band compris es electrically conductive yarns in the longitudinal direction of the band.
  • a knitted, woven, or twined textile band is known from publication US 6727197, for use in connection with, for example, wearable electronics or intelli gent fabrics.
  • the band comprises optical or electrically conductive fibres.
  • a flat, woven cable is known to be used in connection with clothing.
  • the cable consists or longitudinal yarns and a lateral, flexible fibre.
  • the longitudinal yarns are formed of an elastic filament, con ductors spirally wound around the filament, and an insulating layer.
  • the problem with the arrangement described first in the above is that the band is relatively stiff and does not yield in the longitudinal direction.
  • the problem with the arrangement described second in the above is that it is difficult to disassemble conductors wound around the filament to reveal the ends of the conductors.
  • lt is thus an object of the invention to develop a product which may be relatively freely stretched and which, when unloaded, returns to its substantially original dimension.
  • the object of the invention is achieved by a product charac terised by what is disclosed in the independent claims. Preferred embodiments of the invention are disclosed in the dependent claims.
  • the invention is based on the band being stretchy in its longitudinal di rection and reversible from a stretched condition.
  • the band structure comprises longitudinal elastic yarns which are arranged to bind to the structure as yarns separate from the electrically conductive yarns, whereby the band may be stretched without damaging the electrically conductive yarns. Binding as separate yarns from the electrically conductive yarns means that elastic yarns and electri cally conductive yarns do not form an element containing both components in the structure, but both the electrically conductive yarn and the elastic yarn may bind to the structure as separate yarns. However, an electrically conductive yarn and elastic yarn may bind into each other in the structure.
  • an advantage of an elastic band is that is conforms to the surface to which it is fixed ln addition, the band has all the usage properties needed in connection with clothing, such as washability.
  • the uses for the band include conductors used in connection with wearable electronics, intelligent fabrics, or robots. Applications for the band in clude medical technology, healthcare, protective clothing, warning systems inte grated into clothes, and instruments athletics.
  • the band may be used, for example, as a conductor between a measurement electrode in a piece of clothing and an in formation gathering unit or in connection with battery or transformer operated devices.
  • electrically conductive yarns all yarns having an adequate conduc tivity from the point of view of the use may be used, but particularly advantageous are metal threads, such as copper wires. Metal threads are easy to connect to mat ing surfaces, such as electrodes in the clothing. Metal threads may consist of one or more electrically conductive metal filaments and an insulating layer around them.
  • the band may be manufactured by weav ing, in particular by weaving with the Jacquard technology.
  • Jacquard technology refers to a weaving technology in which each warp thread may be lifted inde pendently of other warps, in other words, each warp thread may be individually controlled.
  • elastic yarns are tensioned, whereby the yarn, when untensioned, shortens in the longitudinal direction into wavelike as concerns its cross-section, or into a structure otherwise shortened as to its length.
  • the band When the band is to be fixed to another mating surface, it may be stretched as needed.
  • a woven band such as a band woven with the Jacquard technology, consists of a basic structure and a connecting area at both ends of the band.
  • the basic structure may be a longitudinal tubular element within which the electrically conductive yarn resides. There may be a plurality of parallel tubular elements.
  • the electrically conductive yarn may bind to the basic structure inside the tubular el ement, or it may run freely inside the tubular element.
  • the basic structure does not necessarily have any tubular elements, but the electrically conductive yarn / conductive yarns runs / run protected inside the weave of the band either binding or not binding to the basic structure of the yarn.
  • a specific advantage of a woven band is that the width of the band and the number of electrically conductive yarns may be increased or decreased as needed by introducing more warp threads or not using some of the warp threads ln addition, the length of the yarn may be adjusted exactly as needed, in other words, the basic structure may be woven to a length suitable for each purpose.
  • An advantage of a yarn woven with the Jacquard technology is that the electrically conductive yarns may at a particular manufacturing stage be woven so that they do not bind to other yarns but remain as free yarns on the band surface. When the band is cut at such a point, the electrically conductive yarns are ready to be connected to the places between which they conduct electricity.
  • the band may be woven with the warp knitting technology.
  • Warp knitting technology refers to a knitting technology in which the yarns that form loops run in the longitudinal direction of a fabric.
  • the simplest warp knitting weave is a chain weave in which the yarns form loop chains separate from each other.
  • a uniform knit is formed by a tricot stitch which binds to the adjacent loop in different lines.
  • Other warp knitting weaves include the satin and velvet stitches, for example.
  • the weave of a warp knit may consist of the aforementioned basic weaves, their combinations, or variations.
  • the band is manufactured by the warp knitting technology so that the basic weave is formed by the warp knit which binds the electrically conductive yarns and elastic yarns to the structure.
  • the warp knit may have a weft thread that binds the band in the lateral direction.
  • the electrically conductive yarns are bound by means of the basic weave so that the electrically conductive yarns form a plu rality of adjacent yarn paths in which the yarn runs in the longitudinal direction of the band, zigzagging from right to left and left to right.
  • the elastic yarns run sub stantially straight in the longitudinal direction of the band, with the basic weaves binding them in place.
  • Figures la and lb show a manufacturing pattern of a band according to the invention.
  • Figure lc is a side view of a band according to the invention.
  • Figure 2a and 2b are principled images of the stretching mechanism of a band according to the invention.
  • Figure 2c shows a manufacturing pattern of a band according to the in vention
  • Figures 3a and 3b are cross-sections of yarns according to the inven tion. Detailed description of the invention
  • Figures la and lb show a manufacturing pattern of the band according to the invention.
  • the woven band comprises electrically conductive yarns, elastic yarns, and yarns forming the basic structure of the band.
  • FIGS la and lb show warp threads 1 to 8.
  • the warp threads 1 to 6 are yarns that form the basic structure, and they may be of polyamide, for exam ple. The fineness of the yarns may be 110 x 2 dtex, for example.
  • the warp thread 7 is of elastic fibre material, such as elastane.
  • the warp thread 8 is an electrically conductive yarn.
  • the weft thread may be a yarn forming the basic structure, such as the same yarn as the warp threads 1 to 6. ln a finished product, the warp threads are usually present as multiples, in other words, the warp threads 1 to 8 are repeated in parallel a number of times in the same order.
  • a band may have, for example, 56 warp threads of which 42 warp threads are yarns forming the basic structure, such as polyamide yarns, 7 warp threads are of elastic fibre material, such as elastane, and 7 warp threads are electrically conductive yarns.
  • Figures la and lb show a grid divided into four parts.
  • the top left of the grid shows a fabric image
  • the bottom left shows the drawing-in of warp ends
  • the top right shows the raising of heald laths
  • the bottom right shows the binding.
  • the vertical square lines are warp threads and hori zontal square lines are weft threads.
  • a square illustrates a point where the warp and weft are one upon the other. When a square is marked, the warp thread is on the weft thread.
  • the drawing-in of warp ends is shown in such a manner that the vertical square lines are warp threads and the horizontal lines are heald laths.
  • the raising of heald laths is presented in such a manner that the vertical square lines are the heald laths to be raised, and the horizontal lines indicate the order of the weft threads ln binding, the vertical square lines refer to the lifters of heald laths and the horizontal ones the heald laths.
  • Figure la shows the manufacturing pattern of a band when the electri cally conductive yarns run inside the band.

  • Figure lc is a side view of the inventive band 1.

  • the elastic warp threads of the band 1 are woven tensioned, whereby in an untensioned state the elastic warp threads shorten, and the area A of the band 1 seems wavelike or otherwise collapsed when seen from the side.
