Abstract

Method for manufacturing yarn from at least one bundle of filaments, preferably from semi-synthetic or synthetic materials. In order to achieve qualities similar to natural fibre qualities directly during manufacturing while avoiding the staple yarn process, the filament bundle (5) has to be gathered and held at intervals, and filaments isolated from the filament bundle have to be discontinued (6a, 6b, 7a, 7b) between the binding points thus formed. The gathering of the filament bundle at intervals may for example be effected by heat-sealing or kinking. The yarn thus formed may further be worked by torsioning, twisting, doubling etc...

Description

Verfahren zur Herstellung von GarnProcess for the production of yarn
Die Erfindung betrifft ein Verfahren zur Herstellung von Garn aus wenigstens einem eine Vielzahl von Fila¬ menten aufweisenden Filamentbündel, vorzugsweise aus vollsynthetischen oder halbsynthetischen Materialien.The invention relates to a method for producing yarn from at least one filament bundle having a multiplicity of filaments, preferably from fully synthetic or semisynthetic materials.
Es ist bekannt, Endlosgarne in verschiedenartigen Ver¬ fahren zu kräuseln, um dadurch die Eigenschaften der Endlosgarne den Eigenschaften von Naturfasern anzunä¬ hern. Weiterhin ist es bekannt, dieses Ziel dadurch anzustreben, daß die zunächst endlos hergestellten Ka¬ bei in Stücke zerteilt, dann parallelgelegt und in Spinnmaschinen versponnen werden (sog. Stapelfasern bzw. Stapelgarne).It is known to crimp continuous yarns in various methods in order to bring the properties of the continuous yarns closer to the properties of natural fibers. Furthermore, it is known to strive for this goal by dividing the initially endlessly produced Ka into pieces into pieces, then laying them in parallel and spinning them in spinning machines (so-called staple fibers or staple yarns).
Der Erfindung liegt die Aufgabe zugrunde, Endlosgarne zu schaffen, die nach Art der aus Stapelfasern gespon- nenen Garne in ihren Eigenschaften den Eigenschaften textiler Naturfasern nahekommen, ohne daß jedoch der aufwendige gesonderte Spinnvorgang erforderlich ist.The invention has for its object to provide continuous yarns which, in the manner of the yarns spun from staple fibers, come close in their properties to the properties of textile natural fibers, without, however, the complicated separate spinning process being necessary.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Filamentbündel der eingangs genannten Art in Abstän- den zusammengefaßt und gehalten wird, und daß dann ein¬ zelne Filamente des Filamentbündels unterbrochen wer¬ den. Anstelle des Zerschneidens des Filamentbündels in ■ regelmäßigen oder unregelmäßigen Abständen, des Parallel isierens der so gebildeten Stapelfasern und der an-This object is achieved according to the invention in that the filament bundle of the type mentioned at the beginning is combined and held in intervals, and in that individual filaments of the filament bundle are then interrupted. Regular instead of cutting of the filament bundle in ■ or irregular intervals, the parallel isierens of the staple fibers thus formed and the presence

schließenden Verfestigung durch Drehung zum Halten der Fasern wird das Ziel gemäß der Erfindung in we¬ sentlich einfacherer Weise erreicht. Durch das Unter¬ brechen einzelner Filamente des Filamentbündels in den Abschnitten zwischen den Zusammenfassungsstellen erhält das Garn die gewünschten, den Eigenschaften von Naturfasern nahekommenden Eigenschaften.closing consolidation by rotation to hold the fibers, the goal according to the invention is achieved in a substantially simpler manner. By interrupting individual filaments of the filament bundle in the sections between the gathering points, the yarn obtains the desired properties that approximate the properties of natural fibers.
Das Zusammenfassen des Filamentbündels in Abständen kann in bevorzugter Ausgestaltung der Erfindung durch Verschweißen oder durch Verkräuseln erfolgen. Die Un¬ terbrechung einzelner Filamente des Filamentbündels kann beispielsweise durch Aufschneiden bzw. durch Reis- sen einzelner Filamente des Filamentbündels erfolgen. Die so unterbrochenen Filamente liegen dann jeweils bis zum nächsten Verknüpfungspunkt oder Schweißpunkt lose im Faserverbund 'des Filamentbündels.The filament bundle can be combined at intervals in a preferred embodiment of the invention by welding or crimping. Individual filaments of the filament bundle can be interrupted, for example, by cutting open or by tearing individual filaments of the filament bundle. The filaments thus interrupted then lie loosely in the fiber composite 'of the filament bundle up to the next connection point or welding point.
Das so gebildete Garn kann dann anschließend weiterbe¬ arbeitet werden, beispielsweise durch Drehen, Zwirnen, »Fachen, od. dgl.. Das Material kann im Einfachgarn ge- dreht sein, kann aber auch aus Mehrfachgarn und ohne Drehung im Einfachgarn hergestellt werden. Das Garn kann vor der Bearbeitung gefärbte oder bedruckte Kom¬ ponenten enthalten. Es besteht auch die Möglichkeit, das Garn nach der Herstellung zu färben bzw. zu bedruk- ken. Die Verarbeitung kann auch als rohweiß-Garn erfol¬ gen, und ein Färben oder Bedrucken kann nach dem nach¬ folgenden Herstellungsprozeß (z.B. Weberei oder Tufting) erfolgen.The yarn formed in this way can then be processed further, for example by twisting, twisting, folding, or the like. The material can be twisted in single yarn, but can also be made from multiple yarns and without twisting in single yarn. The yarn may contain colored or printed components before processing. There is also the possibility of dyeing or printing the yarn after production. The processing can also take place as raw white yarn, and dyeing or printing can take place after the subsequent manufacturing process (e.g. weaving or tufting).
Im Vergleich zu den Stapelgarnen ist das erfindungsge- maß erzeugte Garn wesentlich gleichmäßiger, da das er¬ findungsgemäß hergestellte Garn über seine Länge kon¬ stant die gleiche Anzahl von Filamenten aufweist. Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.Compared to the staple yarns, the yarn produced according to the invention is considerably more uniform, since the yarn produced according to the invention has the same number of filaments over its length. The invention is explained below with reference to the drawing.
