Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines gefärbten gezwirnten Garnes gemäss Oberbegriff des Patentanspruches 1.The invention relates to a method for producing a dyed twisted yarn according to the preamble of claim 1.
Zur Herstellung von gefärbten gezwirnten Garnen, bei denen dem Zwirnen ein Fachen vorausgeht, sind je nach Anforderung bezüglich der Ablaufeigenschaften des Endproduktes von der Spule drei oder vier Umspulvorgänge notwendig: der erste Spulvorgang erfolgt beim Fachen, der zweite beim Zwirnen, der dritte nach dem Färben beim Avivieren. Wenn besonders hohe Anforderungen an die Ablaufeigenschaften und die Qualität des Garnes gestellt werden, so wird nach dem Zwirnen das Erstellen einer Präzisionsspule notwendig.For the production of dyed twisted yarns, in which the twisting is preceded by a twist, three or four rewinding operations are necessary, depending on the requirements regarding the unwinding properties of the end product from the bobbin: the first winding operation takes place during the winding, the second during the twisting, the third after the dyeing while finishing. If particularly high demands are made on the run-off properties and the quality of the yarn, it is necessary to create a precision bobbin after twisting.
Bei jedem Umspulvorgang sind nebst den Kosten für diesen Vorgang auch Fadenbrüche nicht auszuschliessen, so dass zusätzliche Verknotungen entstehen, die die Weiterverarbeitung erschweren. Hinzu kommt die unvermeidbare Qualitätsverminderung der Garnoberfläche durch das Umspulen.With each rewinding process, in addition to the costs for this process, thread breaks cannot be ruled out, so that additional knots occur, which make further processing more difficult. Added to this is the inevitable reduction in the quality of the yarn surface due to rewinding.
Die Aufgabe der Erfindung besteht in der Schaffung eines Färbeverfahren für gezwirnte Garne, bei dem mit weniger Umspulvorgängen ein Garn von höheter Qualität und besserer Anfärbung der Einzelfäden an den Kreuzungspunkten erreicht werden kann.The object of the invention is to provide a dyeing process for twisted yarns in which a yarn of higher quality and better dyeing of the individual threads at the crossing points can be achieved with fewer rewinding processes.
Diese Aufgabe wird nach der Erfindung gemäss den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst.This object is achieved according to the invention according to the characterizing features of patent claim 1.
Das bereits im ersten Verfahrensschritt beim Fachen zu einer Präzisionsspule aufgespulte und einen homogenen Spulenaufbau durch ein konstantes Windungsverhältnis und eine konstante Steigung und Fadenabstand der Windungen aufweisende Garn bildet optimale Bedingungen beim Färben, da beim gefachten ungezwirnten Garn eine gleichmässige Einfärbung ohne Farbdifferenzen an den Kreuzungsstellen erreicht werden kann. Die grössere Spulendichte ermöglicht eine Kapazitätserweiterung von 30 - 40 % ohne weitere Investitionen bei verminderten Flottenmenge. Ebenso entfallen das Brechen der Kanten der Spule und Ausschuss auf Grund von Dichtestreuungen, wenn das Einfärben vor dem Zwirnen erfolgt.The yarn spooled into a precision bobbin in the first process step and having a homogeneous bobbin structure due to a constant turn ratio and a constant pitch and thread spacing of the turns creates optimal conditions for dyeing, since the untwisted yarn can be dyed evenly without color differences at the crossing points can. The larger spool density enables a capacity expansion of 30 - 40% without further investments with a reduced fleet quantity. There is also no need to break the edges of the bobbin and broke due to density differences if dyeing takes place before twisting.
Die bis zu 30 % grössere Dichte der Spule und damit kleinere Spule bei gleicher Fadenlauflänge bewirkt beim nachfolgenden Zwirnen eine Einsparung von Energie und Reduktion der Fadenspannung infolge des wesentlich kleineren Ballons. Zudem läuft die Präzisionsfachvorlage vom grossen Spulendurchmesser bis zum kleinen Durchmesser ohne feststellbare Reduktion der Fadenspeicherung auf der Doppeldraht-Spindel ab.The up to 30% greater density of the bobbin and thus a smaller bobbin with the same thread running length results in a saving in energy and a reduction in thread tension due to the much smaller balloon during the subsequent twisting. In addition, the precision compartment template runs from the large bobbin diameter to the small diameter without a noticeable reduction in thread storage on the double-wire spindle.
Der vollständlge Auslauf und die geringeren Stillstandszeiten dank grosser Lauflängen und geringer Knotenzahl senkt die Lohnkosten bei höherer Qualität. Die Einfärbung des ungezwirnten Garnes ergibt einen voluminöseren runden Zwirn, der den Einsatz von OE-Garnen im modischen Strickerei-Oberbekleidungssektor möglich macht.The complete run-out and the short downtimes thanks to long run lengths and a low number of nodes reduce labor costs with higher quality. The coloring of the untwisted yarn results in a more voluminous round thread, which enables the use of OE yarns in the fashionable knitting outerwear sector.
Das erfindungsgemäss Verfahren ermöglicht eine Teilautomatisation bei der Herstellung gefärbter gezwirnter Garne. Anhand eines Ausführungsbeispieles wird die Erfindung näher erläutert.The method according to the invention enables partial automation in the production of dyed twisted yarns. The invention is explained in more detail using an exemplary embodiment.
Im erten Verfahrensschritt werden zwei oder mehr von einer Spule abgezogene OE- oder Ringspinngarne auf einer Präzisionsfachmaschine zu einem Präzisionswickel verarbeitet, dessen homogener Spulenaufbau ein konstantes Windungsverhältnis mit konstanter Steigung und konstantem Fadenabstand der Windungen sowie eine gegenüber einer Wildwickelspule bis 30 % höherer Dichte aufweist.In the first process step, two or more OE or ring spun yarns drawn off a bobbin are processed on a precision specialist machine to form a precision bobbin, the homogeneous bobbin structure of which has a constant winding ratio with constant pitch and constant thread spacing of the windings and a density that is up to 30% higher than that of a winding bobbin.
Im zweiten, dem ersten unmittelbar folgenden Verfahrensschritt erfolgt das Färben des Präzisionswickels, wobei infolge der grösseren Packungsdichte, bzw. grösseren Fadenlänge pro Volumeneinheit eine geringere Menge Farbstoff per Kilogramm Garn notwendig ist, und im Autoklaven können ohne zusätzliche Investitionen 30 - 40 % mehr Garn pro Zyklus gefärbt werden.In the second process step, which follows immediately after the first, the precision winding is dyed, whereby a smaller amount of dye per kilogram of yarn is required as a result of the greater packing density or longer thread length per volume unit, and 30 - 40% more yarn per can be used in the autoclave without additional investment Cycle can be colored.
Im zweiten Verfahrensschritt kann statt gefärbt auch gebleicht werden.In the second process step, bleaching can also take place instead of being colored.
Im dritten Verfahrensschritt erfolgt das Zwirnen des gefachten und gefärbten Garnes direkt ab Präzisionsspule, ab der das Garn infolge geringer Knotenzahl, bester Ablaufeigenschaften gezwirnt werden kann. Wenn zudem beim Färben im letzten Zyklus eine Avivage beigegeben wird, können die Ablaufeigenschaften des Garnes zusätzlich erhöht werden. Die grössere Packungsdichte ergibt bei gleicher Fadenlauflänge kleinere Spulenabmessungen, so dass der Ballon einen ebenfalls geringen Durchmesser aufweist, was zu höherer Leistung der Zwirnmaschine führt.In the third step of the process, the folded and dyed yarn is twisted directly from the precision bobbin, from which the yarn can be twisted due to the low number of knots and excellent run-off properties. If a finishing agent is also added during dyeing in the last cycle, the running properties of the yarn can be increased further. The greater packing density results in smaller bobbin dimensions with the same thread running length, so that the balloon also has a small diameter, which leads to higher performance of the twisting machine.
Während des Zwirnens kann beispielsweise für Nähgarne noch eine Avivierung aufgebracht und im Anschluss daran direkt eine Präzisions-Nähgarnspule erstellt werden.During the twisting process, for example, a finish can be applied to sewing threads and then a precision sewing thread spool can be created directly afterwards.
Das Verfahren erlaubt es, mit OE-, Friktions-oder Jetspinnmaschinen erzeugtem Einfachgarn Zwirne herzustellen, welche bezüglich Gesamtkosten und den Einsatzmöglichkeiten den konventionellen ringgesponnenen Garnen äquivalenter Endnummer ebenbürtig oder überlegen sind.The method allows single yarns produced with OE, friction or jet spinning machines to be produced which are equal or superior to the conventional ring-spun yarns of equivalent end numbers in terms of total costs and possible uses.
Unter den Präzisionswickeln oder -spulen, wie sie zur Durchführung des erfindungsgemässen Verfahrens verwendet oder erstellt werden, versteht man Spulen gemäss den Definitionen wie sie durch die DIN Norm 61 801 vom August 1975 erklärt werden, oder allgemeiner gesagt, Spulen mit Schichten von Präzisionswicklungen. Eingeschlossen sind auch Wickel oder Spulen mit gesteuertem Wicklungsaufbau.Precision coils or coils, as they are used or created to carry out the method according to the invention, are coils according to the definitions as explained by DIN standard 61 801 of August 1975, or more generally, coils with layers of precision coils. Also included are coils or coils with a controlled winding structure.
