The initial twist number of polyamide yarn is around 30 percent smaller than initial twist number of aramid yarn, and the initial twist number of the cord is larger than the initial twist number of the polyamide yarn.

Description

Die Erfindung betrifft einen Hybridkord zur Verwendung als Festigkeitsträger in einer Gürtelbandage eines Fahrzeugreifens aus zwei miteinander verdrehten Garnen, wobei das eine Garn aus Aramid und das andere Garn aus Polyamid, insbesondere Nylon, besteht und beide Garne in die gleiche Richtung erstverdreht sind, und wobei der Hybridkord in die entgegengesetzte Richtung verdreht ist. Die Erfindung betrifft ferner einen Fahrzeugluftreifen, welcher eine Gürtelbandage mit einem derartigen Hybridkord als Festigkeitsträger enthält.The The invention relates to a hybrid cord for use as a strength carrier in a belt bandage of a vehicle tire of two together twisted yarns, with one yarn of aramid and the other Yarn made of polyamide, especially nylon, and both yarns in the same direction are first twisted, and where the hybrid cord is twisted in the opposite direction. The invention relates Furthermore, a pneumatic vehicle tire, which is a belt bandage containing such a hybrid cord as strength carrier.

Bei Fahrzeugluftreifen, die für den Einsatz bei hohen Geschwindigkeiten geeignet sein sollen, ist dafür zu sorgen, dass das Reifenwachstum bei diesen Geschwindigkeiten möglichst gering gehalten wird. Diese Fahrzeugluftreifen weisen daher einen meist mehrlagigen Gürtel auf, welcher radial außerhalb mit einer Gürtelbandage versehen ist. Die Gürtelbandage kann ein- oder mehrlagig ausgeführt sein, erstreckt sich über die gesamte Breite des Gürtels und deckt dabei zumindest die Gürtelränder ab. Die Gürtelbandage enthält üblicherweise parallel zueinander und im Wesentlichen in Umfangsrichtung verlaufende Korde als Festigkeitsträger, die in Gummi eingebettet sind. Bei der Reifenherstellung wird die Bandage aus Materialstreifen, welche die in eine unvulkanisierte Kautschukmischung eingebetteten Korde enthalten, auf den Gürtel durch spiraliges Wickeln bzw. Spulen aufgebracht. Bei der Vulkanisation des Rohreifens in einer Heizform wird der Reifen unter einer gewissen Dehnung in die Form hineingepresst, wobei sich der Reifen üblicherweise im Schulterbereich um ca. 1% bis 2% und im Mittelbereich um ca. 3% bis 4% im Vergleich zum unvulkanisierten Rohling dehnt. Die Festigkeitsträger in der Gürtelbandage sollen nun einerseits bei der Reifenherstellung diese als „Resterhebung” bezeichnete Dehnung in der Reifenheizform zulassen, damit der Reifen präzise ausgeformt werden kann, und andererseits eine gute Hochgeschwindigkeits-Tauglichkeit des fertigen Reifens gewährleisten.at Pneumatic vehicle tires designed for use at high speeds should be suitable, to ensure that the tire growth kept as low as possible at these speeds becomes. These pneumatic vehicle tires therefore have a mostly multi-layered Belt on which radially outward with a Belt bandage is provided. The belt bandage can be executed in one or more layers, extends over the entire width of the belt and covers at least the belt edges off. The belt bandage usually contains parallel to each other and substantially circumferentially extending cords as a strength carrier, which are embedded in rubber. In tire manufacturing, the Bandage made of strips of material, which in an unvulcanized Rubber compound embedded cords included on the belt applied by spiral winding or coils. At the vulcanization of the green tire in a heating mold, the tire is under a certain Stretching pressed into the mold, wherein the tire usually in the shoulder area by approx. 1% to 2% and in the middle area by approx. 3% to 4% compared to unvulcanized blank expands. The strength carriers in the belt bandage should now on the one hand in tire production this elongation, referred to as "recovery" in allow the Reifenheizform so that the tire formed precisely and on the other hand a good high speed capability of the finished tire.

Ein Hybridkord der eingangs genannten Art, welcher als Festigkeitsträger in der Gürtelbandage von Fahrzeugluftreifen geeignet ist, ist beispielsweise aus der DE-A-10 2006 031 780 bekannt. Bei diesem Hybridkord weist das Garn aus Aramid eine Feinheit ≤ 840 dtex und das Garn aus Nylon eine Feinheit ≤ 940 dtex auf. Der Hybridkord ist zudem symmetrisch aufgebaut, indem die Erstverdrehungszahlen der Garne übereinstimmen, wobei beide Garne in gleicher Richtung, entweder in Z- oder in S-Richtung, gedreht sind und die Endverdrehungszahl des Kordes mit den Erstverdrehungszahlen der beiden Garne übereinstimmt, wobei der Kord in entgegengesetzter Richtung zur Drehrichtung der Garne gedreht ist.A hybrid cord of the type mentioned, which is suitable as a strength carrier in the belt bandage of pneumatic vehicle tires, is for example from the DE-A-10 2006 031 780 known. In this hybrid cord, the aramid yarn has a fineness ≤ 840 dtex and the nylon yarn has a fineness ≤ 940 dtex. The hybrid cord is also constructed symmetrically by matching the initial twist counts of the yarns, with both yarns rotated in the same direction, in either the Z or S directions, and the final twist count of the cord coinciding with the first twist counts of the two yarns, with the cord in FIG opposite direction is rotated to the direction of rotation of the yarns.

Ein weiterer, aus Aramid- und Nylon-Garnen bestehender Kord, welcher als Festigkeitsträger in der Gürtelbandage eines Fahrzeugluftreifens vorgesehen ist, ist aus der US-A-2004/0118499 bekannt. Dieser Hybridkord weist beispielsweise eine Konstruktion 1100/3 + 940/1 dtex, verdreht mit 14Z/3S/9S Turns per Inch, oder eine Konstruktion 1100/2 + 940/1 dtex, verdreht mit 12Z/3S/7S Turns per Inch, auf. Auch der aus der WO-97/06297 bekannte Hybridkord besteht aus einem Garn aus Aramid und einem zweiten Garn aus Polyamid, wobei der Hybridkord zumindest zu 75 Gewichtsprozent aus dem hochmoduligen Aramid-Garn bestehen soll.Another, consisting of aramid and nylon yarns cord, which is provided as a strength carrier in the belt bandage of a pneumatic vehicle tire, is from the US-A-2004/0118499 known. This hybrid cord has, for example, a 1100/3 + 940/1 dtex twisted at 14Z / 3S / 9S turns per inch, or a 1100/2 + 940/1 dtex twisted at 12Z / 3S / 7S turns per inch , Also from the WO-97/06297 known hybrid cord consists of a yarn of aramid and a second yarn of polyamide, wherein the hybrid cord is to consist of at least 75 percent by weight of the high modulus aramid yarn.

Der Erfindung liegt die Aufgabe zugrunde, einen als Festigkeitsträger in der Gürtelbandage eines Fahrzeugluftreifens geeigneten Hybridkord der eingangs genannten Art derart auszuführen, dass die Hochgeschwindigkeitstauglichkeit von Reifen mit diesem Kord in der Gürtelbandage deutlich verbessert ist.Of the Invention is based on the object as a strength carrier suitable in the belt bandage of a pneumatic vehicle tire Hybrid cord of the type mentioned in such a way, that the high speed capability of tires with this Cord in the belt bandage is significantly improved.

Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, dass die Erstverdrehungszahl des Polyamid-Garnes um mindestens 30% geringer ist als die Erstverdrehungszahl des Aramid-Garnes, und dass die Endverdrehungszahl des Kordes größer ist als die Erstverdrehungszahl des Polyamid-Garnes und kleiner oder gleich ist der Erstverdrehungszahl des Aramid-Garnes.Solved the object is achieved according to the invention by that the initial twist count of the polyamide yarn is at least 30% is less than the initial twist count of the aramid yarn, and that the final twist count of the cord is greater is as the initial twist count of the polyamide yarn and smaller or equal to the initial twist count of the aramid yarn.

Bei erfindungsgemäß „asymmetrisch” ausgeführten Hybridkorden wirkt daher bei kleinen Dehnungen vorrangig das Garn mit dem kleineren Elastizitätsmodul, das Polyamid-Garn. Dies ist besonders vorteilhaft für die Resterhebung des Rohreifens in der Heizform Bei größeren Dehnungen wirkt hauptsächlich das Garn mit dem höheren Elastizitätsmodul, das Aramid-Garn, wodurch das Umfangswachstum bei hoher Geschwindigkeit gering gehalten wird. Durch den im Vergleich zu einem symmetrisch aufgebauten Hybridkord, wie er beispielsweise aus der DE-A-10 2006 031 780 bekannt ist, geringeren Nylonanteil im Hybridkord kann sich der Kord optimal an die gestellten Anforderungen – Zulassen der Resterhebung und geringes Umfangswachstum bei hoher Geschwindigkeit – anpassen.In accordance with the invention, therefore, in the case of "asymmetrically" executed hybrid cords, the yarn with the smaller modulus of elasticity, the polyamide yarn, primarily acts with small strains. This is particularly advantageous for the recovery of the green tire in the heating mold. At higher strains, the yarn with the higher elastic modulus, the aramid yarn, mainly acts, whereby the circumferential growth is kept low at high speed. By compared to a symmetrically constructed hybrid cord, as he, for example, from the DE-A-10 2006 031 780 is known, lower nylon content in the hybrid cord, the cord can optimally adapt to the requirements - Allow the recovery and low growth at high speed - adapt.

Eine optimale Anpassung an die erwähnten Anforderungen lässt sich mit Hybridkorden erzielen, bei welchen die Erstverdrehungszahl des Aramid-Garnes zwischen 100 T/m und 550 T/m und die Erstverdrehungszahl des Polyamid-Garnes mindestens 70 T/m beträgt.An optimal adaptation to the mentioned requirements can be achieved with hybrid cords, in which the initial twisting number of the aramid yarn between 100 T / m and 550 T / m and the Erstverdre of the polyamide yarn is at least 70 T / m.

Dabei sollten das Aramid-Garn und das Polyamid-Garn jeweils eine Feinheit von 250 dtex bis 3000 dtex aufweisen.there The aramid yarn and the polyamide yarn should each have a fineness from 250 dtex to 3000 dtex.

Die Erfindung betrifft ferner einen Fahrzeugluftreifen in Radialbauart mit einem mehrlagigen Gürtel und einer den Gürtel radial außen abdeckenden Gürtelbandage, welche als Festigkeitsträger einen erfindungsgemäß ausgeführten Hybridkord enthält.The The invention further relates to a radial type vehicle pneumatic tire with a multi-layered belt and a belt radially outside covering belt bandage, which as a strength carrier carried out according to the invention Contains hybrid cord.

Die Erfindung wird im Folgenden, insbesondere anhand von Ausführungsbeispielen, näher beschrieben.The The invention will be described below, in particular with reference to exemplary embodiments, in which described in more detail.

Ein Hybridkord gemäß der Erfindung besteht aus zwei miteinander verzwirnten Garnen A und B, wobei Garn A ein Filamentgarn aus Aramid und Garn B ein Filamentgarn aus Polyamid, insbesondere Nylon, ist. Sowohl das Garn A als auch das Garn B weisen eine Feinheit zwischen 250 dtex und 3000 dtex auf. Das Garn A aus Aramid weist eine Erstverdrehung mit einer Verdrehungszahl von 100 T/m bis 550 T/m (Turns pro Meter), entweder in Z-Richtung oder in S-Richtung, auf. Auch das Garn B aus Polyamid erhält eine Erstverdrehung in Z-Richtung oder in S-Richtung, wobei die Drehrichtung mit jener des Garnes A übereinstimmt, und seine Verdrehungszahl um mindestens 30% geringer ist als die Verdrehungszahl des Garnes A. Die kleinste Verdrehungszahl des Garnes B beträgt 70 T/m.One Hybrid cord according to the invention consists of two twisted yarns A and B, yarn A being a filament yarn of aramid and yarn B a filament yarn of polyamide, in particular Nylon is. Both the yarn A and the yarn B have a fineness between 250 dtex and 3000 dtex. The yarn A of aramid has a first twist with a twist number of 100 T / m to 550 T / m (turns per meter), either in the Z direction or in the S direction, on. The yarn B made of polyamide receives a first twist in the Z direction or in the S direction, with the direction of rotation with that of yarn A, and its twisting number at least 30% less than the twist count of the yarn A. The smallest twist count of the yarn B is 70 T / m.

Die Garne A und B werden zu einem Hybridkord endverdreht, dessen Drehrichtung entgegengesetzt ist zu jener der Garne A und B. So wird bei einer Drehrichtung S der Garne A und B der Kord in die Richtung Z gedreht. Die Verdrehungszahl des Kordes ist größer als die Verdrehungszahl des Garnes B, aber kleiner oder gleich der Verdrehungszahl des Garnes A, es gilt daher:
T/m des Garnes B < T/m des Kordes ≤ T/m des Garnes A.The yarns A and B are final twisted to a hybrid cord whose direction of rotation is opposite to that of the yarns A and B. Thus, in a direction of rotation S of the yarns A and B, the cord is rotated in the direction Z. The twist count of the cord is greater than the twist count of the yarn B, but less than or equal to the twist count of the yarn A, it therefore applies:
T / m of the yarn B <T / m of the cord ≤ T / m of the yarn A.

In der nachstehenden Tabelle 1 sind für einige Beispiels von Hybridkorden, die gemäß der Erfindung ausgeführt und mit Hybridkord I, II, III und IV bezeichnet sind, die dtex-Werte der Garne und die Verdrehungszahlen der Aramid- und Nylon-Garne sowie die Verdrehungszahl des jeweiligen Hybridkordes angegeben.
