Description
Zweitägiges, permanent elektrisch leitfähiges, textiles Flächengebilde zum Schutz gegen nieder- und hochfrequente elektromagnetische FelderTwo-day, permanently electrically conductive textile fabric for protection against low and high frequency electromagnetic fields
Stand der TechnikState of the art ;;
In bestimmten Bereichen der Arbeitswelt müssen Personen gegen nieder- und hochfrequente elektromagnetische Felder wirksam geschützt werden. Der Schutz von Personen gegen elektromagnetische Felder wird in der Bundesrepublik Deutschland durch DIN VDE 0848 geregelt. Dieser Schutz ist typischerweise erforderlich:In certain areas of the working world, people must be effectively protected against low and high frequency electromagnetic fields. The protection of people against electromagnetic fields is regulated in the Federal Republic of Germany by DIN VDE 0848. This protection is typically required:
- bei Arbeiten an Hochspannungsleitungen, die unter Spannung stehen- when working on high-voltage lines that are live
- bei der Bedienung von Hochfrequenz- öfen, -schweißgeräten, u.a.- when operating high-frequency ovens, welding machines, etc.
- bei Arbeiten an Hochfrequenz - Richtantennen, Radaranlagen etc.- when working on high frequency directional antennas, radar systems, etc.
- im medizinischen Bereich- in health care
- in Laboratorien, Forschungszentren etc.- in laboratories, research centers, etc.
- im militärischen Bereich, z.B. für Flugplatzpersonal- in the military sector, e.g. for airfield personnel
- zum Schutz von Herzschrittmacher-Trägern- to protect pacemaker wearers
- u.a.m..- etc.
Für obige Anwendungen werden bisher nur einfache, leitfähige Gewebe angeboten, die hauptsächlich für die Fertigung von Arbeitsschutz - Oberbekleidung verwendet werden. Für Herzschrittmacher-Träger sind zum Teil auch Oberhemden und Blusen für auf dem Markt. Durch die Eigenheiten der Gewebekonstruktion und durch die Standard-Konfektionierung sind die Träger der aus diesen Materialien hergestellten Schutzbekleidung starken Einschränkungen in der Art der Verwendung und des Aussehens dieser Schutzbekleidung ausgesetzt.For the above applications, only simple, conductive fabrics are currently available, which are mainly used for the manufacture of protective workwear. There are also some shirts and blouses on the market for pacemaker wearers. Due to the peculiarities of the fabric construction and the standard manufacturing, the wearers of protective clothing made from these materials are exposed to severe restrictions in the type of use and appearance of this protective clothing.
Problem Problem ::
Der in Anspruch 1 genannten Erfindung liegt die Idee zu Grunde, ein permanent leitfähiges, textiles Flächengebilde zu entwickeln, das im Bezug auf die Vielfalt der Anwendungen und der äußeren Gestaltungsmöglichkeiten in der Funktion als Schutz gegen nieder- und hochfrequente elektromagnetische Felder praktisch keine Einschränkung für den Träger bedeutet.The invention mentioned in claim 1 is based on the idea of developing a permanently conductive, textile surface structure which, in terms of the variety of applications and external design options, means practically no restrictions for the wearer in its function as protection against low and high frequency electromagnetic fields.
Dieses Produkt soll:This product is intended to:
- als Oberbekleidung (mit entsprechender Schnitt-Konstruktion) tragbar sein- be wearable as outerwear (with appropriate cut construction)
- direkt unter der eigentlichen Oberbekleidung zu tragen sein, sei es eine Arbeitskleidung (wie Arbeitskittel etc.), eine Arbeitsschutzbekleidung, die in ihrer Funktion noch andere Schutzaufgaben zu erfüllen hat, oder eine beliebige Straßen-Oberbekleidung- be worn directly under the actual outer clothing, be it work clothing (such as work coats, etc.), protective work clothing that has to fulfil other protective functions, or any street outer clothing
- als Unterbekleidung (Unterwäsche) zu tragen sein, somit gleichzeitig einen angenehmen, hautfreundlichen Charakter aufweisen- can be worn as underwear, thus having a pleasant, skin-friendly character
- pflegeleicht sein- be easy to maintain
- keinen Verlust der eigentlichen Schutzwirkung durch Wäsche/Reinigung erleiden- do not suffer any loss of the actual protective effect through washing/cleaning
- möglichst viele Gestaltungsmöglichkeiten bei der Konfektionierung bieten.- offer as many design options as possible during assembly.
Erfindung : Invention :
Vorstehende Problemstellung wird mit den Maßnahmen unter Anspruch 1 in jedem Punkt grundsätzlich gelöst.The above problem is fundamentally solved in every respect with the measures under claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 + 3 beschrieben.Advantageous embodiments of the invention are described in claims 2 and 3.
Zur Sicherung der hohen elektrischen Leitfähigkeit, gleichbedeutend mit wirksamer Abschirmung nieder- und hochfrequenter elektromagnetischer Felder, dient die Ausgestaltung nach Anspruch 3, wobei zugleich durch die in Anspruch 1 beschriebene doppellagige Konstruktion auch der angenehme Tragekomfort (Hautfreundlichkeit) sichergestellt wird.The design according to claim 3 serves to ensure high electrical conductivity, which is equivalent to effective shielding of low and high frequency electromagnetic fields, while at the same time the double-layered construction described in claim 1 also ensures pleasant wearing comfort (skin-friendliness).

Ein Ausfuhrungsbeispiel der Erfindung wird nachstehend im Detail beschrieben :An embodiment of the invention is described in detail below:
- Oberseite : Textiles Mischgarn, bestehend aus 80 % Polyester - Stapelfasern und 20 % rostfreien Stahlfasern, Durchmesser 8 &mgr;/Qualität DIN 1.4404 (Chrom - Nickel Molybdän - Stahllegierung).- Top: Textile blend yarn consisting of 80% polyester staple fibers and 20% stainless steel fibers, diameter 8 μ/quality DIN 1.4404 (chrome - nickel molybdenum - steel alloy).
- Unterseite : Reines Baumwollgarn (100 %)- Bottom: Pure cotton yarn (100%)
Ein doppelseitiges Gewirk in der Wirkart Interlock, Punti di Roma o.a., Flächengewicht 150 180 g/m2. A double-sided knitted fabric in the Interlock, Punti di Roma or other knitting style, basis weight 150-180 g/m 2 .
Anwendung:Application:
Aus dem oben beschriebenen Gewirk werden Damen- und Herrenunterhemden sowie Unterhosen oder Bodys konfektioniert, wobei die Unterseite aus reinem Baumwollgarn besteht. Die (ärmellosen) Unterhemden sowie die Bodys weisen relativ enge Arm/Achsel - Ausschnitte auf. Der Ausschnitt am Hals reicht in der Höhe knapp unter die durchschnittliche Kragenhöhe. Diese Ausfuhrung ist typisch zum Schutz von Herzschrittmacher-Trägem.The fabric described above is used to make women's and men's undershirts, underpants or bodysuits, with the underside made of pure cotton yarn. The (sleeveless) undershirts and bodysuits have relatively narrow arm/armpit cutouts. The neck cutout is just below the average collar height. This design is typical for protecting people who wear pacemakers.
Bodys und Unterhosen reichen in der Regel etwa bis zu 1/3 der Oberschenkellänge. Diese Konstruktion ist typisch für Genitalien-Schutz z.B. gegen Hochfrequenzstrahlung.Bodysuits and underpants usually reach about 1/3 of the thigh length. This design is typical for genital protection, e.g. against high frequency radiation.
Die Abschirmung der als Ausfuhrungsbeispiel beschriebenen Konstruktion beträgt im Frequenzbereich zwischen 50 MHz - 100 GHz ca. 20 - 40 dB.The shielding of the construction described as an example is approximately 20 - 40 dB in the frequency range between 50 MHz - 100 GHz.
