Abstract

The invention concerns a process for preparing an ordered, textile yarn sheet for immediate further processing, in particular in a tufting machine. In this process, oiled wool is condenser-spun and coned. A multiplicity of ends, specifically all the ends required for further processing, are unwound in parallel from the cones. The sheet of parallel ends is continuously washed and dried and made available for further processing. <IMAGE>

Description

Beim Herstellen von getufteten Teppichen ist es üblich, daß die Spinnerei der Teppichfabrik Garn auf Kreuzspulen zur unmittelbaren Weiterverarbeitung im Teppich liefert. Von den Kreuzspulen läßt sich eine größere Schar paralleler Fäden abziehen und der Tuftingmaschine zuführen. Für die Qualität des Teppichs ist die Vorbehandlung des Garns in der Spinnerei von Bedeutung. Man unterscheidet hier zwischen nach dem konventionellen Streichgarn-Spinnverfahren und dem trocken gesponnenen Streichgarn-Spinnverfahren hergestellten Garnen.When manufacturing tufted carpets, it is common for the carpet mill's spinning mill to deliver yarn on packages for immediate further processing in the carpet. A larger group of parallel threads can be drawn off from the packages and fed to the tufting machine. Pretreatment of the yarn in the spinning mill is important for the quality of the carpet. A distinction is made here between yarns produced by the conventional carded yarn spinning process and the dry spun carded yarn spinning process.

Bei dem konventionellen Streichgarn-Spinnverfahren wird die aus 100 % Wolle bestehende Rohware gegebenenfalls nach einem vorherigen Waschvorgang und einer weiteren Vorbehandlung, bei der die Wolle geöffnet wird und gegebenenfalls verschiedene Wollarten gemischt und eventuell gefärbt werden, einer Schmälzbehandlung unterworfen, damit sie leichter und gleichmäßiger versponnen werden kann. Nach dem Krempeln und Spinnen auf Spinnkopse wird das Garn auf Stränge gehaspelt und dann gewaschen. Das Waschen ist für die Qualität des Teppichs wichtig, weil sich hierbei im Unterschied zu der Wäsche der Rohware ein geringer Restfettgehalt garantieren läßt, der einer vorzeitigen Anschmutzung des Teppichs entgegenwirkt. Hinzu kommt, daß beim Waschen eine Verfilzung der Fasern im Faden eintritt, die einem Abwollen des Teppichs im Gebrauch, also einer Abnutzung des Teppichs, entgegenwirkt. Nach dem Waschen des Garns im Strang erfolgt entweder in der Spinnerei oder später in der Teppichfabrik ein Spulen auf Kreuzspulen, von denen dann die Schar paralleler Fäden für die Verarbeitung in der Tuftingmaschine abgezogen wird.In the conventional carded yarn spinning process, the raw material consisting of 100% wool is optionally subjected to a sizing treatment after a previous washing process and a further pretreatment in which the wool is opened and, if appropriate, different types of wool are mixed and possibly dyed subjected so that it can be spun more easily and evenly. After carding and spinning on spinning bobbins, the yarn is coiled on strands and then washed. Washing is important for the quality of the carpet, because in contrast to the washing of the raw goods, a low residual fat content can be guaranteed, which counteracts premature soiling of the carpet. In addition, the fibers in the thread become matted during washing, which counteracts a swelling of the carpet in use, that is, wear of the carpet. After washing the yarn in the skein, winding takes place on cross-wound bobbins either in the spinning mill or later in the carpet factory, from which the set of parallel threads is then drawn off for processing in the tufting machine.

Bei dem trocken gesponnenen Streichgarn-Spinnverfahren wird zum Teil auf das Schmälzen der gewaschenen Rohwolle und das Waschen des Garns zur Gänze verzichtet. Das nach dem Spinnen auf Spinnkopse gespulte Garn wird von der Spinnerei auf Kreuzspulen umgespult und der Teppichfabrik zur unmittelbaren Weiterverarbeitung zur Verfügung gestellt. Dieses Verfahren hat gegenüber dem konventionellen Verfahren den Vorteil, daß es wegen des Wegfalls des Haspelns sowie Waschens und auch wegen des Spulens vom Spinnkops im Vergleich zum Spulen vom Strang billiger ist, hat aber den Nachteil, daß die Qualität eines aus einem solchen Garn hergestellten Teppichs nicht so gut wie die eines Teppichs aus nach dem konventionellen Verfahren hergestellten Garn ist.In the dry spun carded yarn spinning process, the washing of the washed raw wool and the washing of the yarn are entirely dispensed with. The yarn wound on spinning bobbins after spinning is rewound by the spinning mill on packages and made available to the carpet factory for immediate further processing. This method has the advantage over the conventional method that it is cheaper compared to winding from the strand because of the elimination of reeling and washing and also because of winding from the spinning cop, but has the disadvantage that the quality of a carpet made from such a yarn is not as good as that of a carpet made from yarn made by the conventional method.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen von Garn für die Weiterverarbeitung, zum Beispiel in einer Tuftingmaschine zu schaffen, bei dem das Garn die gleiche Qualität wie beim konventionellen Verfahren hat, das aber bezogen auf das Endprodukt einen geringeren Aufwand erfordert.The invention has for its object to provide a method for producing yarn for further processing, for example in a tufting machine, in which the yarn has the same quality as in the conventional method, but one based on the end product requires less effort.

Diese Aufgabe wird erfindungsgemäß mit einem Verfahren zum Herstellen einer geordneten textilen Fadenschar zur unmittelbaren Weiterverarbeitung durch folgende Verfahrensschritte gelöst:

  • a) Aus geschmälzter Wolle werden nach dem Streichgarn-Spinnverfahren Fäden gesponnen und auf Spulkörper gespult.
  • b) Von einer Vielzahl von Spulkörpern werden alle für die Weiterverarbeitung benötigten Fäden parallel abgezogen.
  • c) Die Schar parallel abgezogener Fäden wird im kontinuierlichen Durchlauf gewaschen und getrocknet und der Weiterverarbeitung zugeführt.
This object is achieved according to the invention with a method for producing an ordered textile thread group for immediate further processing by the following method steps:
  • a) Threads are spun from melted wool using the carded yarn spinning process and wound onto bobbins.
  • b) All threads required for further processing are drawn off in parallel from a large number of bobbins.
  • c) The coulter of threads drawn in parallel is washed and dried in a continuous pass and sent for further processing.

In der Regel schaltet man zum Zwecke der Reinigung (Entfernen von dicken und dünnen Stellen im Faden) einen Spulvorgang ein, bei dem von den beim Spinnen anfallenden Spinnkopsen auf Kreuzspulen übergewechselt wird. Notwendig ist diese Zwischenstufe aber nicht. Denkbar ist, daß zum Beispiel aus modischen Gründen mit den im Faden verbleibenden dünnen und dicken Stellen ein optischer Effekt bewußt angestrebt wird.As a rule, for the purpose of cleaning (removal of thick and thin spots in the thread), a winding process is switched on, in which the spinning heads that occur during spinning are switched to cross-wound bobbins. However, this intermediate stage is not necessary. It is conceivable that, for example for fashion reasons, the thin and thick spots remaining in the thread are deliberately aimed at an optical effect.

Die Weiterverarbeitung der gewaschenen und getrockneten, parallel abgezogenen Fäden kann darin bestehen, daß die Fäden direkt in einer Tuftingmaschine verarbeitet werden. Sie kann aber auch darin bestehen, daß die Fäden zunächst auf einem Baum parallel aufgewickelt werden, von dem sie dann abgezogen und in einer Maschine für die Herstellung des Endproduktes verarbeitet werden können.The further processing of the washed and dried, parallel drawn threads can consist in that the threads are processed directly in a tufting machine. However, it can also consist in that the threads are first wound in parallel on a tree, from which they can then be drawn off and processed in a machine for the production of the end product.

Bei dem erfindungsgemäßen Verfahren läßt sich die Rohware aufgrund der Schmälzbehandlung optimal verspinnen. Durch die spätere Wäsche lassen sich ein geringer Restfettgehalt garantieren und eine Verfilzung der Fasern erreichen, was für die Qualität des Endproduktes wichtig ist. Der dafür zu treibende Aufwand ist jedoch gering, weil im Vergleich zu dem konventionellen Verfahren das Haspeln auf Stränge und das Spulen von den Strängen auf Kreuzspulen entfällt. Im folgenden wird die Erfindung anhand eines Arbeitsflußdiagramms näher erläutert.In the method according to the invention, the raw material can be optimally spun due to the smelting treatment. Subsequent washing guarantees a low residual fat content and a matting of the fibers, which is important for the quality of the end product. However, the effort required for this is low because, compared to the conventional method, there is no reeling on strands and winding from the strands on cross-wound bobbins. The invention is explained in more detail below on the basis of a work flow diagram.

Die zu verspinnende, in der Regel gewaschene Rohwolle wird in der Spinnerei zunächst einer Vorbehandlung unterworfen, die das Öffnen der Wolle, das Durchmischen der Wolle und das Ausscheiden grober Unreinigkeiten umfaßt. Die Vorbehandlung kann auch das Färben umfassen. Bei dieser Vorbehandlung erfolgt das Schmälzen. Nach dem Schmälzen erfolgt die Herstellung des Vorgarns durch Teilen des beim Krempeln entstandenen Flors in Streifen und Nitscheln. Aus diesem Vorgarn wird dann Garn gesponnen und auf Spinnkopse aufgespult.The raw wool to be spun, as a rule washed, is first subjected to a pretreatment in the spinning mill, which involves opening the wool, mixing the wool and removing coarse impurities. The pretreatment can also include dyeing. Melting takes place during this pretreatment. After the roving, the roving is produced by dividing the pile that is formed when carding into strips and nitscheln. Yarn is then spun from this roving and wound onto spinning bobbins.

Die vollgesponnenen Spinnkopse werden der Spinnmaschine entnommen, der Spulmaschine vorgelegt, in der dicke und dünne Stellen entfernt werden, und auf Kreuzspulen aufgespult. Diese Kreuzspulen werden in einem Gatter aufgesteckt, das sich für einen parallelen Abzug der Fäden von den Kreuzspulen eignet. Die so abgezogene Fadenschar wird im kontinuierlichen Durchlauf durch eine Waschmaschine und einen Trockner gewaschen und getrocknet. Nach dem Trocknen wird die Fadenschar über einen Fadenspeicher, der zum Zwecke eines eventuellen Längenausgleichs zwischen den einzelnen Fäden dient, geleitet und unmittelbar weiterverarbeitet, und zwar entweder in der Tuftingmaschine, oder sie wird auf einen Baum aufgewickelt, von dem dann die Fadenschar später für die Verarbeitung im Endprodukt, zum Beispiel zum Tuften abgezogen wird.The fully spun spinning bobbins are removed from the spinning machine, placed in the winder, in which thick and thin spots are removed, and wound on packages. These cross-wound bobbins are plugged into a creel which is suitable for a parallel withdrawal of the threads from the cross-wound bobbins. The thread sheet drawn off in this way is washed and dried in a continuous pass through a washing machine and a dryer. After drying, the thread sheet is passed through a thread storage device, which is used for the purpose of a possible length compensation between the individual threads, and processed immediately, either in the tufting machine or it is wound up on a tree, from which the String of threads is later pulled off for processing in the end product, for example for tufting.

An das Tuften schließt sich noch ein Beschichtungsvorgang an, um die getufteten Fäden in dem Träger des Endproduktes zu verankern.The tufting is followed by a coating process in order to anchor the tufted threads in the carrier of the end product.
