- the filament yarn is wrapped around a roll, which is arranged on a holding element via several springs. In cooperation with the roll wrapped in filament yarn and the springs, the filament yarn is given a thick point at certain intervals.
- Another state of the art is to produce sections with different melting temperatures in man-made fibers in that they are not heated in sections of their length when stretched under the action of heat (DE 38 41 525 AI).
- stretch rollers with grooves are used, in the area of which the fila duck are not heated.
- a device for carrying out this method has a stretching field delimited by an input delivery unit and an output delivery unit, with the filament yarn in between is arranged in the stretching field heat-supplying device (DE 196 26 032).
- This heat-supplying device is designed as at least one disk driven via a turning axis with at least one area with a reduced radius with respect to the axis of rotation.

The filament yarn (1) with sections is textured, after which the sections (20) of the filament yarn are post-drawn. For this purpose a texturing field (II), followed by a post-drawing field (III), is located downstream from a pre-drawing field (I).
Description
Verfahren und Vorrichtung zum Herstellen eines Effektgarnes aus einem endlosen, synthetischen FilamentgarnMethod and apparatus for producing an E f fe k tgarnes of an endless, synthetic filament yarn
Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Herstellen eines Effektgarnes aus einem endlosen synthetischen Filamentgarn, welches Abschnitte unterschiedlicher Dicke und/oder Orientierung bzw. Kristallinität aufweist.The invention relates to a method and a V orrichtung for producing a fancy yarn from a continuous synthetic filament yarn which portions differences d Licher thickness and / or orientation and crystallinity.
Als Stand der Technik ist es bereits bekannt (JP-Hei-6-17337) , aus mindestens einem endlosen, synthetischen, thermoplastischen Filament bestehendes Garn absichtlich mit zufällig oder regelmäßig verteilten Dickstellen zu versehen. Hierzu wird gemäß einer Ausführungsform dieser bekannten Konstruktion das Filamentgarn um eine Rolle herumgeschlungen, welche über mehrere Federn an einem Halteelement angeordnet ist. Im Zusammenwirken mit der vom Filamentgarn umschlungenen Rolle und den Federn wird dem Filamentgarn in bestimmten Abständen jeweils eine Dickstelle kraftschlüssig aufgegeben.As prior art, it is already known (JP-Hei-6-1 7337), of at least one endless, synthetic thermoplastic filament yarn consisting intentionally randomly d o to provide it regularly distributed thick places. For this purpose, according to an embodiment of this known construction, the filament yarn is wrapped around a roll, which is arranged on a holding element via several springs. In cooperation with the roll wrapped in filament yarn and the springs, the filament yarn is given a thick point at certain intervals.
Weiterer Stand der Technik ist, in Chemiefasern Abschnitte mit unterschiedlichen Schmelztemperaturen dadurch zu erzeugen, daß sie bei unter Wärmeeinwirkung erfolgendem Recken in Abschnitten ihrer Länge nicht erwärmt werden (DE 38 41 525 AI) . Hier finden Reckwalzen mit Nuten Anwendung, in deren Bereich die Fila ente nicht erwärmt werden.Another state of the art is to produce sections with different melting temperatures in man-made fibers in that they are not heated in sections of their length when stretched under the action of heat (DE 38 41 525 AI). Here, stretch rollers with grooves are used, in the area of which the fila duck are not heated.
Neben dem vorgenannten bekannten Stand der Technik wurde außerdem bereits vorgeschlagen, daß das Recken in mindestens zwei Reckfeldern mit unterschiedlichem Reckverhältnis erfolgt, wobei die Aufteilung des Gesamtreckverhältnisses auf die beiden Reckfelder kurzzeitig verändert wird (DE 195 29 315.0-26). Eine Vorrichtung zur Durchführung dieses Verfahrens weist ein durch ein Eingangslieferwerk und ein Ausgangslieferwerk be- grenztes Reckfeld auf, wobei dazwischen eine dem Filamentgarn
im Reckfeld wärmezuführende Vorrichtung angeordnet ist (DE 196 26 032) . Diese wärmezuführende Vorrichtung ist als mindestens eine über eine Drechachse angetriebene Scheibe mit mindestens einem Bereich verminderten Radius in bezug auf die Drehachse ausgebildet.In addition to the above-mentioned prior art d e WUR also been proposed that the stretching is done in at least two draw fields with different draw ratio, wherein the division of the total stretch ratio is changed briefly to the two stretching fields (DE 195 2 9 31 5. 0-26) . A device for carrying out this method has a stretching field delimited by an input delivery unit and an output delivery unit, with the filament yarn in between is arranged in the stretching field heat-supplying device (DE 196 26 032). This heat-supplying device is designed as at least one disk driven via a turning axis with at least one area with a reduced radius with respect to the axis of rotation.
Die Erfindung geht also von Verfahren zum Herstellen von mit Abschnitten unterschiedlicher Ausreckung und damit Dicke versehenen Filamentgarnen aus endlosem monofilen oder multi- filen, synthetischen Filamentgarn aus, bei denen die vorgenannten Abschnitte durch unvollständiges Ausrecken eines nicht voll orientierten Filamentgams erzeugt werden. Derartige Filamentgarne haben jedoch den Nachteil, daß in den nicht voll ausgereckten Dickstellen bzw. in den vorgenannten Abschnitten im Laufe der Zeit, insbesondere unter dem Einfluß von Licht, die Festigkeit stark abnimmt.The invention is therefore based on methods for producing filament yarns with sections of different stretching and thus thickness from endless monofilament or multifilament, synthetic filament yarn, in which the aforementioned sections are produced by incomplete stretching of a filament yarn that is not fully oriented. Filament yarns of this type have the disadvantage, however, that the strength in the not fully stretched thick areas or in the aforementioned sections decreases significantly over time, in particular under the influence of light.
Entsprechend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren bzw. eine Vorrichtung zu schaffen, mit welchen Effektgarne der eingangs genannten Art erzeugt werden, die gegen Lichteinwirkung beständig sind.Accordingly, the present invention has for its object to provide a method and an apparatus with which fancy yarns of the type mentioned are produced, which are resistant to the action of light.
Diese Aufgabe wird erfindungsgemäß gelöst durch Texturieren mit Abschnitten unterschiedlicher Ausreckung versehenen Fila- mentgarns mit anschließendem Nachrecken dieser Abschnitte. Es werden also folgende Verfahrensschritte durchgeführt:This object is achieved according to the invention by texturing filament yarn provided with sections of different stretching and subsequently stretching these sections. The following process steps are carried out:
Erzeugen von mit Abschnitten unterschiedlicher Ausreckung versehenem Filamentgarn, Texturieren dieses Filamentgams, - Recken dieses Filamentga s so, daß die Abschnitte unterschiedlicher Ausreckung nachgereckt werden.Production of filament yarn provided with sections of different stretching, texturing of this filament yarn, stretching of this filament gas so that the sections of different stretching are stretched.
Hierbei kann das Erzeugen der Abschnitte unterschiedlicherHere, the generation of the sections can be different
Reckung auf beliebige bekannte Weise nach dem Stand der Tech- nik erfolgen, beispielsweise durch unvollständiges Recken
eines nicht voll orientierten Filamentgams durch wiederholtes Unterbrechen des Reckvorganges bzw. durch Erhöhen des Widerstandes gegen das Recken.Stretching can take place in any known manner according to the state of the art, for example by incomplete stretching a not fully oriented filament yarn by repeatedly interrupting the stretching process or by increasing the resistance to stretching.
Das Texturieren des Filamentgams kann beispielsweise über Falschdrallen, Stauchkräuseln oder Luftblastexturieren durchgeführt werden.The texturing of the filament yarn can be carried out, for example, using false twists, upsetting crimping or air-blasting texturing.
Bei dem Nachrecken, d.h. dem dritten Verfahrensschritt, wird die Textur der Fadenabschnitte aufgehoben; sie werden dadurch zu glatten Fadenabschnitten zwischen den texturiert verbleibenden, schon vor dem Texturieren ausgereckten, dünnen Fadenabschnitten. Durch das Nachrecken, welches maximal als Ausrecken bis zum natürlichen Reckgrad mit weitestgehender Orien- tierung erfolgen kann, wird auch deren Anfälligkeit gegen Lichteinwirkung zumindest in wesentlichem Maße reduziert.When stretching, i.e. the third step, the texture of the thread sections is removed; as a result, they become smooth thread sections between the textured remaining, thin thread sections stretched out before texturing. The post-stretching, which can be carried out at most as stretching up to the natural degree of stretching with the greatest possible orientation, also reduces their susceptibility to the effects of light at least to a substantial extent.
Als Zwischenprodukt soll ein Filament erzeugt werden, das Abschnitte aufweist, die anschließend noch wesentlich gereckt werden können.As an intermediate product, a filament is to be produced which has sections which can subsequently be substantially stretched.
Nach dem Texturieren werden diese noch ausreckbaren Abschnitte ebenso voll ausgereckt wie die bereits im ersten Schritt voll ausgereckten. Das entstehende Garn weist auf seiner ganzen Länge (im wesentlichen) gleiche Substanzmenge im Querschnit auf. Es entsteht also ein auf seiner ganzen Länge voll ausgerecktes Filamentgarn, das texturierte und glatte und damit dicker und dünner erscheinende Abschnitte aufweist. Daß diese beiden Arten von Abschnitten darüber hinaus auch unterschied- liehe Orientierung und Kristallinität aufweisen, ist vorteilhaft. Insbesondere die erhöhte Kristallinität erhöht nämlich beim Anfärben die Tiefe des Effektes.After texturing, these sections that can still be stretched out are stretched out as fully as those that were fully stretched out in the first step. The resulting yarn has (essentially) the same amount of substance in cross-section over its entire length. The result is a filament yarn that is fully stretched along its entire length and has textured and smooth, and thus thicker and thinner, sections. It is advantageous that these two types of sections also have different orientations and crystallinity. In particular, the increased crystallinity increases the depth of the effect when staining.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben. Die
einzige Zeichnung zeigt eine schematische Seitenansicht einer Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens.The invention is described below with reference to an embodiment shown in the drawing. The only drawing shows a schematic side view of an apparatus for performing the method according to the invention.
Gemäß der einzigen Zeichnung läuft ein endloses, synthe- tisches, teilweise orientiertes und nicht voll ausgerecktes Filamentgarn 1 über einen Rillenfadenführer 2 zu einer Lieferwalze 3. Anschließend wird ein Vorreckfeld I erreicht, welches zwischen der Lieferwalze 3 und einer Galette 5 vorliegt. Hier kann eine wärmezuführende Vorrichtung 4 angeordnet sein, wel- ehe beispielsweise aus einer über eine Drehachse angetriebenen, beheizten Scheibe mit mindestens einem Bereich verminderten Radius in bezug auf die Drehachse ausgebildet ist. In diesem Vorreckfeld I werden durch unterschiedliches, wechselndes Ausrecken Abschnitte 20 unterschiedlicher Dicke in dem Filamentgarn 1 erzeugt.According to the single drawing, an endless, synthetic, partially oriented and not fully stretched filament yarn 1 runs over a grooved thread guide 2 to a delivery roller 3. A pre-stretching field I is then reached, which is present between the delivery roller 3 and a godet 5. A heat-supplying device 4 can be arranged here, which is formed, for example, from a heated disk driven via an axis of rotation with at least one region of reduced radius with respect to the axis of rotation. In this stretching field I, sections 20 of different thickness are produced in the filament yarn 1 by different, alternating stretching.
In diesem Vorreckfeld I werden durch wechselnden Reckgrad oder durch Aussetzen des Reckens in dem Filamentgarn 1 Abschnitte 20 mit geringerer Ausreckung zwischen den Abschnitten mit höherer, insbesondere voller Ausreckung erzeugt.In this pre-stretching field I, sections 20 with less stretching are produced between the sections with higher, in particular full, stretching by changing the degree of stretching or by suspending stretching in the filament yarn.
An dieses Vorreckfeld I schließt sich ein Texturierfeld II an, in welchem ein Fixier-Heizelement 10 sowie mindestens ein Texturieraggregat 11 angeordnet ist. In diesem Texturierfeld II wird das Filamentgarn 1' texturiert, beispielsweise mittels des als Falschdrallspindel ausgebildeten Texturieraggregates 11.This pre-stretching field I is followed by a texturing field II, in which a fixing heating element 10 and at least one texturing unit 11 are arranged. The filament yarn 1 ′ is textured in this texturing field II, for example by means of the texturing unit 11 designed as a false twist spindle.
Das Texturierfeld II wird definiert durch die Galette 5 und eine im Abstand davon liegende Fadenfördervorrichtung, welche beispielsweise als Galette 6 ausgebildet ist.The texturing field II is defined by the godet 5 and a thread conveying device located at a distance therefrom, which is designed, for example, as a godet 6.
An dieses Texturierfeld II schließt sich ein Nachreckfeld III an, welches durch eine im Abstand von der Galette 6 liegende Fadenfördervorrichtung 7, beispielsweise eine Galette, gebil-
det ist. In diesem Nachreckfeld III werden die im Reckfeld I nicht voll ausgereckten Abschnitte 20 nachgereckt, insbesondere voll ausgereckt. Bei diesem Nachrecken der Abschnitte 20 wird die Textur dieser Fadenabschnitte aufgehoben; sie werden dadurch zu glatten Fadenabschnitten 20' zwischen den textu- riert verbleibenden, schon vor dem Texturieren ausgereckten dünnen Fadenabschnitten.This texturing field II is followed by a post-stretching field III, which is formed by a thread conveying device 7, for example a godet, located at a distance from the godet 6. det. In this stretching field III, the sections 20 which are not fully stretched in the stretching field I are stretched, in particular fully stretched. During this stretching of the sections 20, the texture of these thread sections is removed; they thereby become smooth thread sections 20 'between the textured remaining thin thread sections stretched out before the texturing.
Es ist vorteilhaft, das aus dem Nachreckfeld III auslaufende Filamentgarn noch durch eine nicht näher dargestellte Set-Zone zu führen. Hier werden die im Nachreckfeld bearbeiteten Fadenabschnitte z.B. unter Wärmeeinwirkung fixiert.It is advantageous to pass the filament yarn running out from the post-stretching field III through a set zone (not shown in more detail). The thread sections processed in the post-stretching field are e.g. fixed under the influence of heat.
Hierdurch wird Effektgarn 1 ' ' erzielt, welches aus dicker erscheinenden, texturierten Abschnitten zwischen dünner erscheinenden, glatten Abschnitten besteht und in dem beide Arten von Abschnitten einen Reckgrad aufweisen, der sie in hohem Maße gegen Lichteinwirkung beständig macht.This achieves fancy yarn 1 ″, which consists of thicker, textured sections between thinner, smooth sections and in which both types of sections have a degree of stretching, which makes them highly resistant to the effects of light.
Dieser Effekt kann durch Färben des Filamentgams oder eines aus ihm hergestellten Flächengebildes (Gewebe, Gewirk, Gestrick) noch wesentlich gesteigert werden. Nicht nur daß die texturierten Abschnitte eine ganz andere Farbwiedergabe aufweisen als die glatten Abschnitte, sondern die glatten Ab- schnitte haben auch eine höhere Kristallinität als die texturierten Abschnitte und demgemäß eine abweichende Anfärbbar- keit.
This effect can be significantly increased by dyeing the filament yarn or a fabric made from it (fabric, knitted fabric, knitted fabric). Not only do the textured sections have a completely different color rendering than the smooth sections, but the smooth sections also have a higher crystallinity than the textured sections and accordingly a different dyeability.
