Definitions

  • the invention relates to a method for producing an electrically conductive combination thread and to an antistatic double fabric made therefrom, which is suitable for furnishing "clean rooms” and as clean room clothing.
  • Fabrics and clothing for "cleanest rooms” in the field of microelectronics, medicine, pharmacy, technical ceramics, the film and sound carrier industry are mostly equipped with polyester silk fabrics, which show sufficient particle emissions, but protect the components, e.g. 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 foil. As a result, these threads are unsuitable for the intended use in the purest rooms, since only the thin edges of the middle layer of metal are exposed and the static electricity cannot be sufficiently dissipated.
  • non-textured monofilaments which have a large number of electrically conductive particles which are applied or embedded on the surface of the monofilaments and thus achieve electrical conductivity.
  • This electrically conductive monofilament is twisted with at least one chemical silk, which is not textured and is not electrically conductive.
  • the fabrics made from these silks and the clothing made from them are suitable for "clean rooms" because of their low particle emission and good electrical conductivity, but they are susceptible to disruption of the displacement of its individual components against one another when exposed to mechanical forces. This can lead to disturbances in the conductivity of the tissue due to damage to the conductive component.
  • fabrics for "cleanest rooms” are flat fabrics into 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.
  • the usage behavior e.g. the long-term effectiveness of the conductivity can be reduced.
  • thread breaks This can lead to local interruptions in continuous electrical conductivity.
  • Such a break in the fine wire detaches it from the constructional structure and causes poor clothing physiological behavior.
  • the reason for breaking lies in the low resistance to kinking and cracking as well as in the low elasticity of the fine wire.
  • FR-PS 1 557 379 discloses a method and an apparatus for producing crimped threads and products made therefrom.
  • a metallic, electrically conductive surface design, “winding”, is realized in two stages by means of a hollow spindle system known per se by means of a winding spinning I twisted process.
  • a thread product is produced by means of a two-stage twisting process within a closed technological process.
  • the disadvantage here is that the product obtained is a thread with a hairy texture which is not suitable for use in clean room clothing.
  • the invention has for its object to provide a method for producing an electrically conductive combination thread and an antistatic double fabric made therefrom that is suitable for the equipment of "clean rooms” and as “clean room clothing”, with which a complete discharge of static electricity ensures is and in the presence of a textile character, the basis for the production of a double 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 by a method for producing an electrically conductive combination thread for "cleanest rooms” or for clean room clothing using a component of synthetic silk and a component of metal wire, in which the division takes place by means of a separate compartment and twisting press, which are twisted by a classic double wire connects, the electrically conductive component with 20% low tension / thread tension to the synthetic silk being guided in a helical line to the thread surface in an electrically conductive manner.
  • This combination thread produced according to the method provides one with a thread tension level approximately 8% of the fineness-related tensile strength of the synthetic silk made of a mixture of synthetic silk with a metal wire.
  • the metal component consists of a commercially available chrome-nickel-molybdenum alloy, which is unusual in the spinning sector.
  • the component of the combination thread made of synthetic silk is textured in the nozzle.
  • the invention is advantageously designed if, according to the method, a polyester silk produced by the nozzle process with extremely low elasticity behavior is used as the core component of the combination thread, the thread tension application of the core component with known, infinitely adjustable thread brakes being a maximum of up to 12% of the thread breaking force.
  • the sheath component consists of a metal wire of known chrome-nickel-molybdenum alloy.
  • the invention is embodied by a method for producing a conductive combination thread with a core component, for which a polyester silk with a low elasticity behavior is used, the thread breaking force is 12% and thread tension on the core component is achieved with continuously adjustable thread brakes, whereby a Metal wire is on a rotating drain body spool and the core component is wound by means of a winding process based on the hollow spindle principle with the metal wire in a screw-like form at a spindle speed of 10500 rpm and a winding speed of 350 windings per meter.
  • This combination thread is advantageously used in a double weave in a variety of warp and weft directions. It is characteristic that in addition to this combination thread, a large number of non-textured and / or non-conductive chemical silk according to the invention are to be used in both fabric directions.
  • the weave of the double weave should preferably be designed so that the conductive combination thread is bound in a plurality in the warp and weft directions so 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 double weave advantageously has a large number of thread crossings in order to ensure minimal particle emission and particle permeability.
  • the object of the invention is further achieved in that the electrically conductive combination thread is flexibly incorporated into multi-surface antistatic double fabrics, the electrically conductive combination thread loosely binding in the upper fabric and the lower fabric stabilizing the unstable elastic upper fabric.
  • the lower fabric binds the upper fabric with the non-electrically conductive threads.
  • the non-electrically conductive warp threads of the lower fabric are arranged in the immediate vicinity of the electrically conductive combination thread, which lie in the warp direction.
  • the non-electrically conductive lower warp threads bind with the non-electrically conductive weft threads in plain weave L 1/1.
  • non-electrically conductive lower warp threads also bind to 4 non-electrically conductive upper weft threads like a canvas.
  • the non-conductive weft threads of the lower fabric thus exert an additional protective 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 is effectively retained with electrical conductivity.
  • This double weave construction means that the electrically conductive combination thread can be loaded at least 25% more.
  • the particle permeability is significantly reduced in addition to the described effect. Added to this is the fact that the lower tissue is worn on the skin and a significantly better clothing physiological effect can also be achieved.
  • This double 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 double 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.
  • the core component is manufactured in such a way that a winding process which works according to the hollow spindle principle is carried out, in which the polyester silk which is produced by the nozzle process and has a low elasticity behavior is the core component.
  • the thread tension is applied to this core component by means of known, continuously adjustable thread brakes up to a maximum of 12% of the thread breaking force.
  • the core component is wrapped in a continuous helix by a metal wire sheath. It is located on a rotating pay-off spool with approximately parallel winding and wraps around this core component evenly with a little-moving thread balloon at a spindle speed of 10,500 rpm and a number of windings of 350 rpm.
  • non-electrically conductive lower warp threads also bind to 4 non-electrically conductive upper weft threads like a canvas.
