Definitions

  • the invention relates to an electrically conductive Combine a - tion ply and a woven fabric made therefrom, which is suitable for the furnishing of "clean rooms” as well as a clean room clothing.
  • Fabrics and clothing for "clean rooms" in the field of microelectronics, medicine, pharmacy, technical ceramics, the film and sound carrier industry are predominantly equipped with polyester silk fabrics, which show sufficient particle emissions, but protect the components, e.g. B. sensitive microcircuits, sensitive integrated circuits and other sensitive semiconductors, do not guarantee against the influence of static electricity.
  • antistatic chemicals in the form of additives in detergents, dishwashing detergents, in the form of sprays are applied to clothing. Although these chemicals reduce the adhesion of the clothing to the body of the wearer, they do not prevent the high static electricity on the surface of the clothing. In addition, such chemicals are not washable
  • Known metal laminate threads have, in addition to a thin, narrow metal foil as the middle layer, a cover layer which consists of a thin plastic film. As a result, these threads are unsuitable for the intended use in clean rooms, since only the thin edges of the middle layer are made of Metal is exposed and the static electricity can not be sufficiently dissipated.
  • Fabrics for "clean rooms” are known to be flat fabrics in which conductive metal fibers or metal threads are incorporated.
  • the conductive threads have a rigid connection due to frequent thread crossings, which stress the thread on bending at very short intervals. So that can the usage behavior, e.g. B. the long-term effectiveness of the conductivity can be reduced. There is a risk of how that z. B. with a mechanical load when wearing the tissue on the body, thread breaks. This can lead to local interruptions in continuous electrical conductivity. Such a break in the fine wire detaches it from the construction structure and causes poor clothing physiological behavior. The reason for breaking lies in the low resistance to buckling and cracking as well as in the low elasticity of the fine wire.
  • the invention has for its object to provide an electrically conductive combination thread and a fabric made therefrom that is suitable for the equipment of "clean rooms” as well as “clean room clothing”, whereby a complete discharge of static electricity is ensured and in the presence of a textile character the basis for the production of a fabric is formed with a fabric construction which is designed using the combination thread so that its tear resistance is increased and the destruction of its individual components is counteracted.
  • the object is achieved in that the electrically conductive combination thread consists of a component of metal wire and a core component of synthetic silk, the electrically conductive component supplied with at least 20% lower tension / thread tension to the synthetic silk being electrically conductive in a helical line on the thread surface.
  • This combination thread provides one with a thread tension level of approximately 8% of the fineness-related tensile strength of the synthetic silk produced mixture of a synthetic silk with a metal wire.
  • the metal component consists of a commercially available, but unusual in the spinning sector chrome-nickel-molybdenum alloy.
  • the component of the combination thread consisting of synthetic silk is textured in the nozzle.
  • the invention is advantageously designed if the core component of the combination thread is a polyester silk produced by the jet process with extremely low elasticity behavior, the tension of the core component with known, infinitely adjustable thread brakes being a maximum of 12% of the thread breaking force.
  • the Man components, flush consists of a metal wire of known chromium-nickel-molybdenum alloy, which is located in a nearly Parallelbewicklung on a rotating flow k örperspule and the core component ungskohl through a balloon of thread in a helical shape at a spindle speed of 10 500 min-1 and a Umwind of 350 turns / min.
  • This combination thread is advantageously used in a fabric in a large number of warp and weft directions. It is characteristic that in addition to this combination thread, a large number of non-textured and / or textured non-conductive chemical silk can be used in both fabric directions.
  • the weave of the fabric should preferably be designed so that the conductive combination thread is available in a variety of The warp and weft directions are integrated in such a way that the conductive component of the combination thread is predominantly arranged on the surface. This ensures good conductivity for the discharge of static electricity.
  • this fabric advantageously has a large number of thread crossings in order to ensure minimal particle emission and particle permeability.
  • the electrically conductive combination thread is flexibly incorporated into multi-surface fabrics, preferably double fabrics, the electrically conductive combination thread loosely binding in the upper fabric and the lower fabric atabilizing the unstable elastic upper fabric.
  • the lower fabric binds with the non-electrically conductive threads of the upper fabric.
  • the non-electrically conductive warp threads of the lower fabric are arranged in the immediate vicinity of the electrically conductive combination wire, which lie in the warp direction.
  • the non-electrically conductive lower warp threads bind with the non-electrically conductive weft threads in plain weave .
  • non-electrically conductive lower warp threads also bind to 4 non-electrically conductive upper weft threads like a canvas.
  • Two electrically conductive threads of the combination thread bind as warp threads within a repeat with all the non-electrically conductive upper weave threads in the repeat in twill weave Z opposed to the body-binding Z upper warp threads.
  • the non-conductive weft threads of the lower fabric thus exert an additional support effect for the electrically conductive threads of the combination thread. The result of this is that the electrically conductive combination thread is subjected to much less kinking and the electrical conductivity is effectively retained.
  • This fabric construction means that the electrically conductive combination thread is at least 25% more resilient.
  • the particle permeability is significantly reduced in addition to the described effect.
  • the lower tissue is worn on the skin and thus additional. Lich a much better clothing physiological effect can be achieved.
  • This fabric advantageously has a large number of thread crossings, so that a minimum particle emission and particle permeability is to be ensured. A pleasant clothing physiological behavior is also guaranteed by the use of textured threads.
  • These fabrics are dyed and / or finished using known technologies and without significant additional expenditure. When assembling such woven and finished surfaces, the assembly parts must be joined together in such a way that as many conductive threads of the combination thread as possible touch.
  • a fabric for clean room clothing can be produced under the following conditions
