Description

Schwimmfähiges Tau  Floatable rope
Beschreibung: Description:
Die Erfindung betrifft ein schwimmfähiges Tau, d.h. ein Tau, das auf dem Wasser schwimmt. The invention relates to a buoyant rope, i. a dew floating on the water.
Solche Taue sind bekannt. JP 2000-303254 und JP 2003-055836 beschreiben jeweils ein schwimmfähiges Tau aus Hohlfasern aus einem thermoplastischen Polymer, z.B. aus Nylon 6, mit einem Anteil des Hohlvolumens am Faservolumen von 10 bis 35 %, wobei die Hohlfasern mindestens zwei Lumina aufweisen. Such ropes are known. JP 2000-303254 and JP 2003-055836 each describe a buoyant dew of hollow fibers of a thermoplastic polymer, e.g. made of nylon 6, with a proportion of the hollow volume at the fiber volume of 10 to 35%, wherein the hollow fibers have at least two lumens.
WO 2009/026215 beschreibt ein Hybrid-Garn aus einer oder mehreren Polyolefin- fasern und einer oder mehreren Verstärkungsfasern. Das Hybrid-Garn kann u.a. zur Bildung faserhaltiger Strukturen einschließlich geflochtener Taue eingesetzt werden. WO 2009/026215 describes a hybrid yarn of one or more polyolefin fibers and one or more reinforcing fibers. The hybrid yarn can i.a. be used to form fibrous structures including braided ropes.
Daher stellt sich die vorliegende Erfindung die Aufgabe, ein weiteres schwimmfähiges Tau zur Verfügung zu stellen. Therefore, the present invention has the object to provide another buoyant rope.
Diese Aufgabe wird gelöst durch ein schwimmfähiges Tau bestehend aus mindestens zwei Strängen, wobei jeder Strang Synthesefasern umfasst, und vorzugsweise jeder Strang aus Synthesefasern besteht, wobei das Tau dadurch gekennzeichnet ist, dass die Synthesefasern eine Komponente A) und eine Komponente B) umfassen, wobei A) mindestens ein Monofilament ist und B) mindestens ein Multifilamentgarn ist, dessen Filamente Hohlfaser-Filamente sind. This object is achieved by a buoyant rope consisting of at least two strands, wherein each strand comprises synthetic fibers, and preferably each strand consists of synthetic fibers, the rope being characterized in that the synthetic fibers comprise a component A) and a component B), wherein A) is at least one monofilament and B) is at least one multifilament yarn whose filaments are hollow fiber filaments.
Überraschenderweise wurde gefunden, dass dadurch, dass die Synthesefasern in jedem Strang des erfindungsgemäßen Taus eine Komponente A) und eine Korn- ponente B) umfassen, wobei A) mindestens ein Monofilament ist und B) mindestens ein Multifilamentgarn ist, dessen Filamente Hohlfasern sind, schwimmfähige Taue hergestellt werden können, die im Vergleich zu Tauen, die zu 100 % aus Multifilamentgarn bestehen, eine deutlich stabilere Seilquerschnittsform aufweisen. Die deutlich stabilere Seilquerschnittsform des erfindungsgemäßen schwimmfähigen Taus hat zur Folge, dass das erfindungsgemäße schwimmfähige Tau im Vergleich zu einem schwimmfähigen Tau ohne Komponente A) die folgenden technischen Vorteile aufweist: Surprisingly, it has been found that the fact that the synthetic fibers in each strand of the rope according to the invention have a component A) and a grain component B), where A) is at least one monofilament and B) is at least one multifilament yarn, the filaments of which are hollow fibers, floatable tows can be produced which have a significantly more stable cable cross-sectional shape compared to tows made of 100% multifilament yarn , The significantly more stable rope cross-sectional shape of the buoyant rope according to the invention has the consequence that the buoyant rope according to the invention has the following technical advantages in comparison to a buoyant rope without component A):
- Ein gleichmäßiges Bewickeln von Winden bzw. von Winschen auf Schiffen wird sicher möglich und der Maximaldurchmesser der Winden wird bei voller Bewicklung nicht überschritten.  - A uniform winding of winches or winches on ships is certainly possible and the maximum diameter of the winches is not exceeded at full winding.
- Ein Unterziehen von Seilsegmenten beim Aufwickeln (z.B. auf Winschen) wird entweder ganz vermieden oder zumindest deutlich reduziert. Die Vermeidung oder zumindest die deutliche Reduzierung des Unterziehens ist eine wesentliche Voraussetzung für ein gleichmäßiges Ablaufen des Seils von der Winde, wodurch die Verletzungsgefahr von Personen durch schlagartig freigegebene untergezogene Seilsegmente vermieden oder zumindest deutlich reduziert wird.  - Underwing of rope segments during winding (for example on winches) is either completely avoided or at least significantly reduced. The avoidance or at least the significant reduction of Unterziehenens is an essential prerequisite for a uniform drainage of the rope from the winds, whereby the risk of injury of persons is avoided by abruptly released untergezogene rope segments or at least significantly reduced.
- Der Reibungswiderstand beim Führen des Taus über Leitorgane, wie z.B.  The frictional resistance in guiding the dew via guiding elements, such as e.g.
Klüsen, wird durch die vergleichsweise niedrige Auflagefläche des Taus auf den Leitorganen reduziert, wodurch das vom Monofilament umgebene Kernmaterial vor Beschädigung durch Abrieb geschützt wird.  Jawing is reduced by the comparatively low contact surface of the dew on the guide elements, whereby the core material surrounded by the monofilament is protected from damage by abrasion.
In einer bevorzugten Ausführungsform des erfindungsgemäßen schwimmfähigen Taus besteht das Tau aus 3 bis 36 Strängen. In a preferred embodiment of the floating buoy according to the invention, the rope consists of 3 to 36 strands.
In einer besonders bevorzugten Ausführungsform des erfindungsgemäßen schwimmfähigen Taus besteht das Tau aus 6 bis 18 Strängen. In a particularly preferred embodiment of the floating dew according to the invention, the rope consists of 6 to 18 strands.
