Definitions
- the invention relates to a method and an apparatus for producing a elastic combination games, consisting of at least two threads, in which one thread (sheath thread) made of a staple fiber yarn made of natural or synthetic fibers, and the other thread (core thread) is elastic endless thread and these threads by swirling by means of a Fluids are brought together.
- the elastic thread during winding or twisting is protected by the surrounding sheath thread while swirling (also called Heilumwinden, Aircovering, Heilumwirbeln) of the elastic thread only more or less periodically mixed with the sheath or the sheath threads lies inside the sheath thread.
- swirling also called Heilumwinden, Aircovering, Heilumwirbeln
- the proportion of the elastic thread should be as small as possible and only so large that the restoring forces in the yarn are sufficiently high.
- both methods have the disadvantage that, in particular when using staple fiber threads as sheath thread, there is no permanent connection between the two threads to be combined.
- WO 95/23886 describes a process in which staple fibers are fed directly to filaments in order to combine them by air-texturing with one another to form a blended yarn.
- this technique has not brought the expected success and could not be implemented in practice.
- the attempt to connect an endless filament yarn with a staple fiber yarn (DE 299 02 103 U1) by means of a swirl generator has not been successful.
- especially natural fibers behave much stiffer and can not be opened so easily during swirling, so that the core thread is not integrated satisfactorily.
- synthesis yarn is generally fed in addition, which are then easier to fluidize, but have the disadvantage that the synthetic material content in the combination yarn is very high.
- the object of the invention is to provide an elastic combination yarn, in which the elastic core thread is stable with one of natural or synthetic Fibers or fiber blends existing mantle thread connected is so that the threads can not slip against each other.
- the staple fiber thread consist of flax or hemp fibers, so in the preparation zone, the fibers adhering to the Pectins dissolved, so that in the union zone a bond done by these pectins with the elastic continuous thread. That's it possible to stably even such stiff staple fibers with elastic threads unite.
- the preparation of the flax or hemp thread is preferably done with steam to dissolve the pectins. Unless the thread is your own Contains adhesives, such as cotton or synthetic fibers the case is in the preparation zone on the fiber yarn thread Adhesive applied.
- the device for producing the combination yarn consists essentially a thread feed for several threads, a preparation unit, an unification unit as well a winding unit, wherein the preparation unit both a heating device as well as additionally or alternatively one Supply for adhesives includes.

Description
Beim Umwinden oder Zwirnen betragen die Prozeßgeschwindigkeiten maximal 15-40m/min, während beim Verwirbeln Prozeßgeschwindigkeiten bis 1200m/min erreicht werden. Diese Verfahren werden besonders häufig bei der Kombination von elastischen Fäden mit Fäden aus natürlichen oder synthetischen Stapelfasern angewendet. Elastische Garne kommen besonders dann zum Einsatz, wenn die textile Fläche knitter- und faltenfrei sein soll, oder beispielsweise bei Kleidungsstücken ein Ausbeulen vermieden werden soll. Daher muß das Garn eine gewisse Rückstellkraft besitzen. Die so erzeugten Garne sind in ihrer Qualität sehr unterschiedlich. So liegt der elastische Faden beim Umwinden oder Zwirnen geschützt durch den ihn umgebenden Mantelfaden, während beim Verwirbeln (auch Luftumwinden, Aircovering, Luftumwirbeln genannt) der elastische Faden nur mehr oder weniger periodisch mit dem oder den Mantelfäden vermischt im Inneren des Mantelfadens liegt. Somit ist im Stoffbild und Warenausfall ein großer qualitativer und optischer Unterschied sichtbar, wobei die Qualität des Stoffes, bei dem das Garn im Umwindeprozeß hergestellt wurde, wesentlich besser ist, da das Garn durch den Mantelfaden eine gute Abdeckung besitzt. Der Anteil des elastischen Fadens soll so gering wie möglich sein und nur so groß, daß die Rückstellkräfte im Garn genügend hoch sind. Beide Verfahren haben jedoch den Nachteil, daß insbesondere beim Einsatz von Stapetfaserfäden als Mantelfaden keine beständige Verbindung zwischen beiden zu kombinierenden Fäden erfolgt. Während der Weiterverarbeitung können dadurch Probleme auftauchen, daß der elastische Faden über den Mantelfaden mangels Verschiebefestigkeit rutscht, es somit zu Fadenspannungsunterschieden im Garn kommt und sich auch Schlingen bilden, die im Weiterverarbeitungsprozeß wie Weben oder Stricken Ablaufstörungen oder auch Stillstände hervorrufen können. Besonders bei der Kombination von Naturfaserfäden mit elastischen Fäden gibt es Probleme in der Weiterverarbeitung, da sich diese Fäden im Gegensatz zu synthetischen Stapelfaserfäden oder Endlosfilamenten wesentlich schlechter verwirbeln lassen und auch keine stabile Verbindung mit dem elastischen Kernfaden zu erreichen ist.
