Description
Die Erfindung betrifft einen elektrisch leitfähigen Kombina- tionszwirn sowie ein daraus hergestellten Gewebe, das für die Ausstattung von "Reinen Räumen" sowie als Reinraumkleidung geeignet ist.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.
Gewebe und Bekleidung für "Reine Räume" im Bereich der Mikroelektronik, Medizin, Pharmazie, Technische Keramik, der Film-und Tonträgerindustrie sind überwiegend mit Polyesterseidengeweben ausgestattet, die zwar eine genügende Partikelemmission zeigen, jedoch den Schutz der Bauelemente, z. B. empfindlicher Mikroschaltkreise, empfindlicher integrierter Schaltkreise und anderer empfindlicher Halbleiter, gegen den Einfluß statischer Elektrizität-nicht gewährleisten.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.
Zur Beseitigung der statischen Elektrizität ist es bekannt, daß antistatisch wirkende Chemikalien in Form von Zusätzen in Waschmitteln, Spülmitteln, in Form von Sprays auf die Kleidung aufgebracht werden. Diese Chemikalien verringern zwar die Haftwirkung der Kleidungsstücke am Körper des Trägers, verhindern aber nicht die hohe statische Elektrizität auf der Oberfläche der Kleidung. Außerdem sind derartige Chemikalien nicht waschbeständigTo eliminate static electricity, it is known that 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
Bekannte Metallaminatfäden weisen, neben einer dünnen, schmalen Metallfolie als Mittelschicht, eine Deckschicht auf, die aus einer dünnen Plastdolie besteht. Dadurch sind diese Fäden für den vorgesehenen Einsatzzweck in reinen Räumen ungeeignet, da nur die dünnen Kanten der Mittelschicht aus Metall offen liegen und die statische Elektrizität damit nicht genügend abgeleitet werden kann.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.
Durch den Einsatz von Metallfasern und Metallfäden in Garn- nen werden zwar Ladungen statischer Elektrizität abgeleitet und zerstreut, aber die daraus gefertigten Gewebe beeinflussen durch die Haarigkeit der Garne die Partikelemmission negativ und sind deshalb für "Reine Räume" nicht geeignet.Through the use of metal fibers and metal filaments in yarn n en although charges are derived static electricity and scattered, but the fabric made therefrom influenced by the hairiness of the yarns, the particle emissions are therefore negative and for "clean rooms" is not suitable.
Es ist bekannt, nichttexturierte Monofilseiden einzusetzen, die eine Vielzahl von elektrisch leitfähigen Teilchen aufweisen, welche auf die Oberfläche der Monofilseiden aufgebracht oder eingelagert sind und damit eine elektrische Leitfähigkeit erreichen. Diese elektrisch leitfähige Monofilseide wird mit wenigstens einer Chemieseide, welche nicht texturiert ist und elektrisch nicht leifähig ist, verzwirnt. Die aus diesen Seiden hergestellten Gewebe und die daraus hergestellte Kleidung eignen sich zwar für "Reine Räume", da eine niedrige Partikelemission und eine gute elektrische Leitfähigkeit vorhanden ist, jedoch sind sie störanfällig gegen die Verschie-bung seiner Einzelkomponenten gegeneinander bei Einwirkung mechanischer Kräfte. Dadurch können Störungen der Leitfähigkeit im Gewebe durch Beschädigung der leitfähigen Komponente entstehen.It is known to use 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 silk 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 subjected to mechanical forces. This can result in tissue conductivity damage due to damage to the conductive component.
Gewebe für "Reine Räume" sind bekannterweise Flachgewebe in welche leitfähige Metallfasern oder Metallfäden eingearbeitet sind.Fabrics for "clean rooms" are known to be flat fabrics in which conductive metal fibers or metal threads are incorporated.
Bei diesen Geweben haben die leitfähigen Fäden eine starre Einbindung durch häufige Fadenkreuzungen, die den Faden in sehr kurzen Abständen auf Biegung beanspruchen. Damit kann das Gebrauchsverhalten, z. B. die Dauerwirksamkeit der Leitfähigkeit, geschmälert werden. Es basteht die Gefahr, wie das z. B. bei einer mechanischen Belastung beim Tragen des Gewebes am Körper, Faden bricht. Damit kann es zu lokalen Unterbrechungen einer durchgehenden elektrischen Leitfähigkeit kommen. Durch einen solchen Bruch des Feindrahtes löst sich dieser aus dem Konstruktionsverband und bedingt ein schlechtes bekleid ungsphysiologisches Verhalten. Die Ursache des Brechens liegt in der niedrigen Knickbruch- und Rißbeständigkeit sowie in der niedrigen Elastizität des Feindrahtes begründet.With these fabrics, 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.
Der Erfindung liegt die Aufgabe zugrunde einen elektrisch leitfähigen Kombinationszwirn sowie ein daraus hergestelltes Gewebe, daß für die Ausstattung von "Reinen Räumen" sowie als "Reinraumkleidung" geeignet ist zu schaffen, wodurch ein vollständiges Ableiten statischer Elektrizität gewährleistet wird und bei dem Vorhandensein eines textilen Charakters die Grundlage für die Herstellung eines Gewebes mit einer Gewebekonstruktion gebildet wird, welche unter Verwendung des Kombinationszwirnes so ausgebildet ist, daß dessen Rißbeständigkeit erhöht und einer Zerstörung seiner Einzelkomponenten entgegengewirkt wird.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.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß der elektrisch leitfähige Kombinationszwirn aus einer Komponente Metalldraht und einer Kernkomponente Syntheseseide, besteht, wobei die mit mindestens 20 % niedrigerer Spannung/ Fadenzugkraft zur Syntheseseide Zugeführte elektriseh Leitfähige Komponente in schraubenförmiger Linie an der Zwirnoberfläche elektrisch leitend anliegt. Dieser Kombinations zwirn stellt eine mit einem Fadenzugkraftniveau von annähernd 8 % der feinheitsbezogenen Reißkraft der Syntheseseide hergestellte Mischung einer Syntheeeseide mit einem Metalldraht dar. Die Metallkomponente besteht aus einer handelsüblichen, jedoch auf dem Spinnereisektor ungebräuchlichen Chrom-Nickel-Molybdän-Legierung.According to the invention 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.
Es ist im Sinne der Erfindung, das die aus Syntheseseide bestehende Komponente des Kombinationszwirnes düsentexturiert ist.It is within the meaning of the invention that the component of the combination thread consisting of synthetic silk is textured in the nozzle.
Die Erfindung ist vorteilhaft ausgestaltet, wenn als Kernkomponente des Kombinationszwirnes eine nach dem Düsenverfahren hergestellte Polyesterseide mit äußerst geringem Elastizitätsverhalten eingesetzt wird, wobei die Fadenzugskraftbeaufsohlagung der Kernkomponente mit bekannten, stufenlos einstellbaren Fadenbremsen maximal bis 12 % der Fadenreißkraft beträgt. Die Man telkomponente besteht aus einem Metalldraht bekannter Chrom-Nickel-Molybdän-Legierung, der mit annähernder Parallelbewicklung sich auf einer rotierenden Ablaufkörperspule befindet und über einen Fadenballon die Kernkomponente in schraubenförmiger Form bei einer Spindeldrehzahl von 10 500 min-1 und einer Umwind ungszahl von 350 Umwindungen/min umwindet.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 ungszahl 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.
Dieser Kombinationszwirn wird vorteilhaft in einem Gewebe in einer Vielzahl in Kett- und Schußrichtung eingesetzte Dabei ist charakteristisch, daß außerdiesem Kombinationszwirn in beiden Geweberichtungen eine Vielzahl nichttexturierter und/oder texturierter nicht leitfähige Chemieseiden einzusetzen sind.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.
Die Bindung des Gewebes ist vorzugsweise so auszulegen, daß der leitfähige Kombinationszwirn in einer Vielzahl in Kett- und Schußrichtung so eingebunden ist, daß die leitfähige Komponente des Kombinationszwirnes überwiegend an der Oberfläche angeordnet ist. Damit wird eine gute Leitfähigkeit für das Abfließen einer statischen Elektrizität erzielt.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.
Außerdem weist dieses Gewebe vorteilhaft eine Vielzahl von Fadenverkreuzungen auf, um eine minimale Partikelemmission und Partikeldurohlässigkeit zu gewährleisten.In addition, this fabric advantageously has a large number of thread crossings in order to ensure minimal particle emission and particle permeability.
Die Aufgabe der Erfindung ist weiterhin dadurch gelöst, das der elektrisch leitfähige Kombinationszwirn flexibel in mehrflächig ausgebildete Gewebe, vorzugsweise in Doppelgewebe, eingebunden wird, wobei der elektrisch leitfähigen Kombinationszwirn im Obergewebe lose bindet und das Untergewebe das labile elastische Obergewebe atabilisiert. Das Untergewebe bindet mit den nicht elektrisch leitfähigen Fäden des Obergewebes ab. Die nicht elektrisch leitfähigen Kettfäden des Untergewebes sind dabei in unmittelbarer Nähe des elektrisch leitfähigen Kombinationswirnes, die in Kettrichtung liegen, angeordnet. Insbesondere binden die nicht elektrisch leitfähigen Unterkettfäden mit den nicht elektrisch leitfähigen Unterschußfäden in Leinwandbindung
Durch diese Gewebekonstruktion ergibt sich, daß der elektrisch leitfähige Kombinationszwirn um mindestens 25 % höher belastbar ist.This fabric construction means that the electrically conductive combination thread is at least 25% more resilient.
Mit der erfindungsgemäßen Gewebekonstruktion wird zusätzlich zu dem beschriebenen Effekt die Partikeldurchlässigkeit entscheidend verringert. Hinzu kommt noch, daß das Untergewebe auf der Haut getragen wird und damit zusätz-. lich ein wesentlich besserer bekleidungsphysiologischer Effekt erzielbar ist.With the fabric construction according to the invention, the particle permeability is significantly reduced in addition to the described effect. In addition, the lower tissue is worn on the skin and thus additional. Lich a much better clothing physiological effect can be achieved.
Dieses Gewebe weist vorteilhaft eine Vielzahl von Fadenverkreuzungen auf, damit eine minimale Partikelemmission und Partikeldurchlässigkeit zu gewährleisten ist. Ein angenehmes bekleidungsphysiologisches Verhalten ist auch durch den Einsatz texturierter Fäden gewährleistet. Gefärbt und/oder ausgerüstet werden diese Gewebe nach bekannten Technologien sowie ohne wesentliche zusätzliche Aufwendungen. Bei der Konfektioniorung solcher gewebter und veredelter Flächen sind die Konfektionsteile so aneinander zufügen, daß sich möglichst viele leitfähige Fäden des Kombinationszwirnes berühren.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.

Elektrisch leitfähiger Kombinationszwirn Nennfeinheit R 25 tex,Electrically conductive combination thread, nominal fineness R 25 tex,
Dieser Faden besteht aus 2 Komponenten,
- einem Metalldraht x 5 Chrom/Nickel/Molybdän 18. 11. 0,036 mm der Nennfeinheit von 8 tex,
- einer weißen nach dem Düsenverfahren reektexturierten Polyesterseide PE-S-rt DS-ws der Nennfeinheit von 16,7 tex f 80
- wird derart hergestellt, daß ein nach dem Hohlspindelprinzip arbeitender Umwindeprozeß vorgenommen wird, bei dem die nach dem Düsenverfahren hergestellte, ein geringes Elastizitätsverhalten aufweisende Polyesterseide die Kernkomponente darstellt. Die Fadenzugkraftbeaufschlagung dieser Kernkomponete erfolgt mittels bekannte, stufenlos einstellbare Fadenbremsen maximal bis 12 % der Fadenreißkraft. Die Kernkomponente wird durch einen Mantelfaden aus Metalldraht in einer kontinuierlichen Schraubenlinie umwunden. Dabei befindet sich dieser mit annähernder Parallelbewicklung auf einer rotierenden Ablaufspule und umwindet diese Kernkomponente über einen wenig bewegten Fadenballon gleichmäßig mit einer Spindeldrehzahl von 10 500 Dr/min und einer Anzahl der Umwindungen von 350 U/min.
- a metal wire x 5 chrome / nickel / molybdenum 18. 11. 0.036 mm of nominal fineness of 8 tex,
- a white polyester silk PE-S-rt DS-ws re-textured by the jet process with a nominal fineness of 16.7 tex f 80
- is produced in such a way that a wrapping 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 these core components by means of known, continuously adjustable thread brakes up to a maximum of 12% of the thread breaking force. The core component is covered by a metal wire sheath in a con wound around the screw line. 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.
