Abstract

Musiksaiten, deren umsponnener Kern aus Aramidfasern besteht. Aufgrund der hohen mechanischen Festigkeit bei kleiner Dichte des verwendeten Polymermaterials können besonders dünne bzw. besonders hohe und besonders modulierbare Musiksaiten hergestellt werden.Musical strings with a wound core made of aramid fibers. Due to the high mechanical strength with a low density of the polymer material used, particularly thin or particularly high and particularly modular musical strings can be produced.

Description

Die Erfindung betrifft Musiksaiten, die einen Kern aus Poly­amidfasern und eine Umspinnung aufweisen.The invention relates to musical strings that have a core made of polyamide fibers and a wound.

Grundsätzlich benötigt jede Musiksaite für eine gewünschte Grundfrequenz bei gegebener Spannung und freier Schwingungs­länge (Mensur) ein bestimmtes Gesamtgewicht je Längeneinheit. Dieses teilt sich in das Gewicht für den die Spannung aufnehmen­den Kern der Saite und das Gewicht der "Umspinnung" zur Klang­modulation der Saite. Wenn nun bei dünnen, langen, hochgestimm­ten Saiten wenig oder kein Restgewicht zur Verfügung steht, kann die Saite nicht moduliert oder überhaupt nicht gebaut werden, sie reißt.Basically, each musical string requires a certain total weight per unit length for a desired basic frequency with a given tension and free vibration length (scale). This is divided into the weight for the tension-absorbing core of the string and the weight of the "wound" for sound modulation of the string. If there is little or no residual weight available with thin, long, tuned strings, the string cannot be modulated or built at all, it breaks.

Ziel der Erfindung ist, ein Kernmaterial für Musiksaiten zu finden, mit dem es möglich ist, beim Kerngewicht zu sparen und Saiten mit besonderem Klange auszustatten.The aim of the invention is to find a core material for musical strings with which it is possible to save on the core weight and to provide strings with a special sound.

Dieses Ziel wird mit Musiksaiten erreicht, bei denen als Kern­material Aramidfasern vorgesehen sind. Aufgrund der besonders günstigen Eigenschaften der erfindungsgemäß verwendeten Aramid­fasern, d.h. hoher spezifischer Festigkeit, höchste Reißlänge, hohem E-Modul, kleiner Bruchdehnung, hoher Härte, hoher Kerbfestigkeit und ge­ringerWasseraufnahme, ist beispielsweise die Herstellung dünner Gitarre- oder hoher Streichsaiten ohne weiteres möglich und z B. ist Silber, ein gutklingender aber schwerer Werkstoff, als Umspinnungsdraht einsetzbar. Beispielsweise hat Aramidfilament­garn, das von der Firma Du Pont unter der Markenbezeichnung Kevlar 49 im Handel ist, folgende physikalischen Eigenschaften: Zugfestigkeit (MPa) 2 760 Höchstzugkraft (cN/tex) 190 Modul (MPa) 120 000 Modul (cN tex) 8 300 Bruchdehnung (%) 1,9 This goal is achieved with musical strings in which aramid fibers are provided as the core material. Due to the particularly favorable properties of the aramid fibers used according to the invention, ie high specific strength, maximum tear length, high modulus of elasticity, low elongation at break, high hardness, high notch resistance and low water absorption, the production of thin guitar or high string strings is easily possible, for example is silver, a good sounding but heavy material, can be used as a core wire. For example, aramid filament yarn, which is sold by Du Pont under the brand name Kevlar 49, has the following physical properties: Tensile strength (MPa) 2,760 Maximum tensile force (cN / tex) 190 Module (MPa) 120,000 Module (cN tex) 8,300 Elongation at break (%) 1.9

Aramide sind Polyamide mit aromatischen Kettengliedern, die zu mindestens 85 % Massenanteil direkt durch Amidgruppen zu linearen Makromulekülen verbunden sind und bei denen bis zu 50% der Amidbindungen durch Imidbindungen ersetzt sein können.

Figure imgb0001

Die Verwendung von Polyamiden als Kernmaterial bei der Sai­tenherstellung ist bekannt. Trotzdem war der Einsatz von Aramid­fasern nicht naheliegend, da eine ihrer Eigenschaften, nämlich ihre sehr guten Schwingungsdämpfungseigenschaften, den Fachmann von ihrem Einsatz als Kernmaterial für Saiten abhielten. Dieser Umstand erklärt auch die Tatsache, daß das erfindungsgemäß ver­wendete Aramidmaterial, obwohl bereits seit anfangs der 60er-­Jahre bekannt und unter verschiedenen Handelsnamen erhältlich, bis zur vorliegenden Erfindung keinen Eingang bei der Saitenherstellung gefunden hat.The use of polyamides as the core material in string production is known. Nevertheless, the use of aramid fibers was not obvious, since one of their properties, namely their very good vibration damping properties, prevented the expert from using them as core material for strings. This fact also explains the fact that the aramid material used according to the invention, although known since the beginning of the 1960s and available under various trade names, has not been used in string production until the present invention.
