Description

Verfahren zum Herstellen eines Fertiggarnes Die Erfindung betrifft ein Verfahren zum Herstellen eines Fertiggarnes, bei dem ein Vorgarn aus endlichen Stapelfasern mit einem oder mehreren im wesentlichen unverstreckten synthetischen Fäden zusammen verzogen und verstreckt wird.Method of Making a Finished Yarn The invention relates to a method for producing a finished yarn in which a roving from finite Staple fibers with one or more substantially undrawn synthetic fibers Threads are twisted and stretched together.

Es ist bekannt, einen oder mehrere endlose synthetische Fäden ohne Verzug dem Ausgangswalzenpaar des Streckwerkes einer Ringspinnmaschine zuzuführen. Hierbei werden der oder die endlosen synthetischen Fäden nach dem Verlassen des Streckwerkes nicht verzogen und von dem aus dem Streckwerk austretenden verzogenen Vorgarn lediglich schraubenlinienförmig ummantelt. Es ist auch bekannt, einen endlosen synthetischen Faden gemeinsam mit den Fasern das Streckwerk einer Ringspinnmaschine durchlaufen zu lassen. Hierbei werden der oder die vollsynthetischen Fäden zuerst verstreckt und dann mit den endlichen Fasern des Vorgarnes zusammen gedreht. Dabei müssen die endlosen synthetischen Fäden die Verstreckung auf einer kurzen zu durchlaufenden Länge aufnehmen.It is known to have one or more endless synthetic threads without To feed the draft to the output roller pair of the drafting system of a ring spinning machine. Here, the or the endless synthetic threads after leaving the The drafting system is not warped and the one emerging from the drafting system is warped Roving only wrapped in a helical shape. It is also known to be an endless one synthetic thread together with the fibers the drafting system of a ring spinning machine to run through. Here, the fully synthetic thread or threads come first drawn and then twisted together with the finite fibers of the roving. Included The endless synthetic threads need to be drawn on a short length to be traversed Record length.

Auch müssen die Fasern des Vorgarnes eine bestimmte Mindestlänge aufweisen. Der Erfindung liegt die Aufgabe zugrunde, die Nachteile der bekannten Verfahren zu vermeiden.The fibers of the roving must also have a certain minimum length. The invention is based on the problem of the disadvantages of the known methods to avoid.

Die Erfindung besteht darin, daß das aus vorzugsweise sehr kurzen Fasern bestehende Vorgarn zusammen mit den synthetischen Fäden dem Lieferwalzenpaar eines Wagenspinners zugeführt wird und das Verstrecken durch Wagenverzug während der Drahtgebung erfolgt.The invention consists in that the preferably very short Fibers existing roving together with the synthetic threads the delivery roller pair a carriage spinner is fed and the stretching by carriage warping during the wire is made.

Voraussetzung für das Verfahren ist, daß die endlosen unverstreckten bzw. vorverstreckten synthetischen Fäden eine plastische Dehnungsfähigkeit aufweisen, die ganz oder zum Teil innerhalb der Verstreckung durch das Streckwerk liegt.The prerequisite for the process is that the endless undrawn or pre-drawn synthetic threads have a plastic extensibility, which is wholly or partly within the stretching by the drafting system.

Durch Haftmittel, chemische Einwirkung oder Wärmebehandlung kann außerdem eine zusätzliche innigere Verbindung der Einzelfasern mit den endlosen Tragfasern erreicht werden.Adhesives, chemical agents or heat treatment can also an additional, more intimate connection of the individual fibers with the endless support fibers can be achieved.

Dadurch, daß das Verstrecken und Drehen erfindungsgemäß gleichzeitig und auf einer größeren Länge durch Wagenverzug erfolgt, ergeben sich Garne mit besonders günstigen Eigenschaften.In that the stretching and turning according to the invention are carried out simultaneously and takes place over a longer length due to carriage warpage, yarns with special result favorable properties.

PATENTANSPRÜCHE: 1. Verfahren zum Herstellen eines Fertiggarnes, bei dem ein Vorgarn aus endlichen Stapelfasern mit einem oder mehreren im wesentlichen unverstreckten synthetischen thermoplastischen Fäden zusammen verzogen und verstreckt wird, dadurch gekennzeichnet, daß das aus vorzugsweise sehr kurzen Fasern bestehende Vorgarn zusammen mit den synthetischen Fäden dem Lieferwalzenpaar eines Wagenspinners zugeführt wird und das Verstrecken durch Wagenverzug während der Drahtgebung erfolgt. PATENT CLAIMS: 1. Method for producing a finished yarn, at which is a roving of finite staple fibers with one or more essentially undrawn synthetic thermoplastic threads drawn together and drawn is, characterized in that it consists of preferably very short fibers Roving together with the synthetic threads to the delivery roller pair of a wagon spinner is fed and the stretching is carried out by carriage distortion during wire making. 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß in an sich bekannter Weise durch Imprägnieren oder durch Hitze die Bindung der kurzen Fasern an die endlosen Fäden unterstützt wird.
