Description
Die Erfindung betrifft ein Kern-Mantel-Garn mit den Merkmalen des Oberbegriffs des Hauptanspruchs.The invention relates to a core-sheath yarn with the features of the preamble of the main claim.
Kern-Mantel-Garne sind bekannt, die aus einem Kern aus Kunststoff-Fäden mit um diesen herumgesponnenem Mantel bestehen, um den Garnen einen textlien Charakter zu geben (US-PS 30 09 311 und US-PS 34 87 628). Bisher hat man sich bezüglich der Festigkeit dieser Garne ganz auf die Festigkeit des Kerns derselben verlassen und den umsponnenen Mantel nur als Mittel betrachtet, um den Garnen einen textlien Charakter zu geben.Core-sheath yarns are known which consist of a core consist of plastic threads with a sheath spun around them, and a textlien around the threads To give character (US-PS 30 09 311 and US-PS 34 87 628). So far, one has to consider the strength these yarns rely entirely on the strength of the core of the same and the covered sheath only regarded as a means of giving the yarns a textile character.
Bei Verwendung dieser bekannten Garne als Schußfäden für Reifencordgewebe '-geben sich ab einer gewissen Zugbeanspruchung der Schußgarne bei der Bombage des Reifenrohlings unterschiedliche Dehnungen der Schußfäden und damit Unwuchten, die zu Ausschuß des betreffenden Reifens führen können. Deshalb sind die bekannten Garne als Schußfäden für Reifencordgewebe wenig geeignet. Ein weiterer Nachteil dieser bekannten Garne liegt darin, daß die elastischen Eigenschaften des Kerns eine gewisse Rückstellung bewirken, die ebenfalls zu Unwuchten der Reifen führen kann.When these known yarns are used as weft threads for tire cord fabric, they are released a certain tensile stress on the weft yarns when the green tire is folded over Stretching of the weft threads and thus imbalances, which can lead to the rejection of the tire in question. The known yarns are therefore not very suitable as weft threads for tire cord fabrics. Another disadvantage This known yarn lies in the fact that the elastic properties of the core have a certain Cause resetting, which can also lead to imbalances in the tires.
Der Erfindung liegt die Aufgabe zugrunde, ein alls Schuß für Cordgewebe von Fahrzeugreifen geeignetes
Kern-Mantel-Garn zu schaffen, das unter den beim Verarbeiten zu Cordgewebe auftretenden Belastungen
formstabil ist, unter den bei der Bombage des ein derartiges Cordgewebe enthaltenden Reifenrohlings
erfolgenden starken Zugbelastungen aber eine gleichförmige Dehnung auf seiner gesamten Lftnge zuläßt.
Diese Aufgabe wird erfindungsgemäß bei einem Kern-Mamel-Garn der eingangs geiwnnten Gattung
mit den Merkmalen des Hauptanspruches gelöst Eine vorteilhafte Ausgestaltung der Erfindung ist Gegenstand
des Unteranspruches,The invention is based on the object of creating a core-sheath yarn suitable for all wefts for cord fabric of vehicle tires, which is dimensionally stable under the loads occurring during processing to cord fabric, but under the strong tensile loads occurring when the tire blank containing such a cord fabric is bent allows uniform elongation over its entire length.
According to the invention, this object is achieved with a core mamel yarn of the type mentioned at the beginning with the features of the main claim.
Ein derartiges Kern-Mantel-Garn weist einen Mantel auf, der bis zu einer bestimmten Zugbelastung des
Garnes die Längung des eine hohe Dehnbarkeit aufweisenden plastisch verformbaren Kernes begrenzt
Ist diese Fließgrenze des aus Stapelfasern gebildeten Mantels überschritten, so verliert er jegliche Zugfestigkeit
so daß bei höherer Zugbelastung der Kern vom Mantel ungehindert bleibend gedehnt wird, und zwar
auf der gesamten Länge gleichförmig aufgrund der dem Kern eigenen Dehnungseigenschaften. Unterhalb der
Fließgrenze des Mantels ist die Dehnung des Kern-Mantel-Garnes ebenfalls auf der gesamten Länge
gleichförmig und wird von den Eigenschaften des Mantels bestimmt
Es ist zwar bekannt (GB-PS 9 71 573), bei aus zwei Komponenten bestehenden Garnen Fäden aus unvollständig
verstrecktem Kunststoff zu verwenden, jedoch wird bei Fertigstellung des Garnes eine Verstreckung
vorgenommen, so daß das Endprodukt praktisch keine plastische Verformbarkeit aufweistSuch a core-sheath yarn has a sheath which, up to a certain tensile load on the yarn, limits the elongation of the plastically deformable core, which has high extensibility Tensile load, the core is stretched unhindered by the sheath, uniformly over the entire length due to the core's own stretch properties. Below the yield point of the sheath, the elongation of the core-sheath yarn is also uniform over the entire length and is determined by the properties of the sheath
Although it is known (GB-PS 9 71 573) to use threads made of incompletely stretched plastic in two-component yarns, a stretching is carried out when the yarn is completed, so that the end product has practically no plastic deformability
In der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäßen Kern-Mantel-Garnes dargestellt, und zwar zeigtIn the drawing, an embodiment of a core-sheath yarn according to the invention is shown, namely shows
Das in F i g. 1 stark vergrößert gezeichnete und in F i g. 2 nochmals weiter vergrößerte Kern-Mantel-GarnThe in Fig. 1 drawn greatly enlarged and in FIG. 2 core-sheath yarn, which has been further enlarged
1 hat einen Kern 2 in Form endloser Fäden aus unverstrecktem Kunststoff wie Nylon oder Polyester, der mit einem Mantel 3 aus Stapelfasern umsponnen ist1 has a core 2 in the form of endless threads made of undrawn plastic such as nylon or polyester, which is wound with a jacket 3 made of staple fibers
Kunststoff bestehen.
Der Kern 2 hat eine starke plastische DehnbarkeitMade of plastic.
The core 2 has a strong plastic ductility
seines Materials bei stärkerer Zugbelastung des Garnes seine Festigkeit während der Kern 2 weiter bleibend gedehnt wird. Dabei reißt der Mantel 3 nicht vom Kernof its material, if the yarn is subjected to a higher tensile load, its strength remains unchanged while the core 2 continues is stretched. The jacket 3 does not tear from the core
2 ab und zeigt auch keine Brüche oder sonstigen Ablöseerscheinungen, sondern folgt allen Bewegungen des Kerns 2.2 and shows no breaks or other detachment phenomena, but follows all movements of the core 2.
