Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines Ledergarns, gekennzeichnet durch folgende Abfolge von Verfahrensschritten: a) das Leder wird zu Lederfasern zerkleinert, b) die Lederfasern werden ausgerichtet, c) die Lederfasern werden zu einem Garn versponnen.The invention relates to a process for producing a leather yarn, characterized by the following sequence of process steps: a) the leather is comminuted to leather fibers, b) the leather fibers are aligned, c) the leather fibers are spun into a yarn.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Ledergarns. The invention relates to a method for producing a leather yarn.

Erfindungsgemäß wird Leder derart zerkleinert, dass es nur noch in Form von Lederfasern vorliegt. Die Lederfasern werden in einer an sich bekannten Weise ausgerichtet, wie sie zum Beispiel in der EP 0 294 571 gezeigt ist, und gegebenenfalls mit einem Adhäsionsmittel versehen. Das Adhäsionsmittel kann ein Kunstharz sein, insbesondere ein Polyamid, Polyethylen oder ein anderes Polymerharz. Durch das Adhäsionsmittel kleben die Fasern gut aneinander so dass sich diese leicht in eine Spinnvorrichtung zu einem Garn verspinnen lassen. Bei dem Verspinnen werden die Fasern in an sich bekannter Weise miteinander verdrillt. According to the invention, leather is comminuted in such a way that it is present only in the form of leather fibers. The leather fibers are aligned in a manner known per se, as for example in the EP 0 294 571 is shown, and optionally provided with an adhesive. The adhesive may be a synthetic resin, in particular a polyamide, polyethylene or other polymeric resin. By the adhesive the fibers stick together well so that they can be easily spun into a spinning device to a yarn. During spinning, the fibers are twisted together in a conventional manner.

Auf diese Weise ist es möglich, einen Ledergarn herzustellen, das in Textilen eingestrickt oder eingewebt werden kann. Insbesondere lässt sich ein derartiges Ledergarn auch in einem Webgestrick als Schuss- und/oder Kettfaden einbinden. In this way it is possible to produce a leather yarn that can be knitted or woven into textiles. In particular, such a leather yarn can also be incorporated in a woven knit as weft and / or warp thread.

In einer Weiterbildung der Erfindung werden die Lederfasern vor dem Verspinnen mit Textilfasern vermischt, wodurch eine Fasermischung erhalten wird. Nach dem Vermischen der Fasern werden diese ausgerichtet, eventuell mit einem Adhäsionsmittel versehen und anschließend versponnen. Durch die Mischung mit herkömmlichen Textilfasern können die Festigkeitseigenschaften des resultierenden Garnes verbessert werden, während gleichzeitig durch eine entsprechende Dosierung der Zugabe der Textilfasern der optische Ledereindruck des resultierenden Garnes erhalten bleibt. Der Anteil an Textilfasern kann in dem Ledergarn vorzugsweise zwischen 10 und 50 Gew.-% liegen In one development of the invention, the leather fibers are mixed before spinning with textile fibers, whereby a fiber mixture is obtained. After mixing the fibers they are aligned, possibly provided with an adhesive and then spun. By blending with conventional textile fibers, the strength properties of the resulting yarn can be improved, while at the same time maintaining the optical leather impression of the resulting yarn by a corresponding dosage of the addition of textile fibers. The proportion of textile fibers in the leather yarn may preferably be between 10 and 50% by weight

In einer Weiterbildung des erfindungsgemäßen Verfahrens werden die Lederfasern mit einem Kunststoff, insbesondere einem Kunstharz als Adhäsionsmittel vermengt und durch eine Düse gepresst. Hierbei entstehen Stapelfasern. Die Fasern können in bestimmten Längen geschnitten werden oder es kann abgewartet werden bis die aus der Düse gepressten Stapelfasern von selbst abbrechen. Die so entstandenen Stapelfasern werden anschließend versponnen. Auf diese Weise werden längere Faserlängen der Stapelfasern erzielt, was letztendlich zu einem stabileren Garn führt. In a further development of the method according to the invention, the leather fibers are mixed with a plastic, in particular a synthetic resin, as an adhesive and pressed through a nozzle. This produces staple fibers. The fibers can be cut in certain lengths or it can wait until the staple fibers pressed out of the die break off by themselves. The resulting staple fibers are then spun. In this way, longer fiber lengths of the staple fibers are achieved, which ultimately leads to a more stable yarn.

Beim Spinnen werden die Lederfasern oder die Stapelfasern durch verdrillen versponnen. Sie können jedoch auch im Rahmen des Verspinnens durch eine Düse gepresst werden zusammen mit dem Adhäsionsmittel. So wird z.B. ein Open-End-Spinnverfahren, Ringspinnverfahren oder Luftspinnverfahren angewandt. Ebenfalls können Rotorspinnverfahren oder andere Spinnverfahren angewandt werden. During spinning, the leather fibers or the staple fibers are spun by twisting. However, they can also be pressed through a nozzle during spinning, together with the adhesive. For example, an open-end spinning process, ring spinning or air spinning process applied. Also, rotor spinning or other spinning processes can be used.

Vorzugsweise kann das entstandene Ledergarn nach dem Verspinnen noch mit einem Trennmittel, z.B. auf Fluor oder Silikonbasis behandelt werden, um die Adhäsionsneigung des Garnes zu verringern und damit die Verarbeitbarkeit des Garnes in späteren textiltechnischen Prozessen zu verbessern. Preferably, the resulting leather yarn after spinning may still be coated with a release agent, e.g. be treated on fluorine or silicone-based, in order to reduce the adhesion tendency of the yarn and thus to improve the processability of the yarn in subsequent textile technology processes.

Vorzugsweise kann das entstandene Ledergarn mit einer Schutzschicht aus Kunststoff ummantelt werden, um die Abnutzungsfestigkeit zu verbessern. Preferably, the resulting leather yarn can be coated with a protective layer of plastic to improve the wear resistance.
