Abstract
Description
Die Erfindung betrifft ein Verfahren zum Co-Spinnen von synthetischen Fäden, aus wenigstens zwei Polymeren auf einer Doppelspinnposition bestehend aus wenigstens zwei nebeneinander angeordneten Spinnpositionen, sowie eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for co-spinning synthetic threads, made of at least two polymers on a double spinning position consisting of at least two spinning positions arranged next to one another, and a device for carrying out this method.
Das Co-Spinnen von synthetischen Fäden aus zwei verschiedenen Polymeren ist bekannt. Das US-Patent 4 025 595 betrifft ein Verfahren zur Herstellung von gemischten Filamenten mit 20 bis 68 Fibrillen und einen Titer zwischen 70 und 260 den, wobei man mindestens zwei Faserbündel co-spinnt, separat verwirbelt, zusammen verstreckt und anschließend bei einem Verwirbelungsgrad zwischen 45 und 80 % verwirbelt. Gemäß diesem Verfahren stellt man vollverstreckte Fäden auf einer Doppelspinnposition her. Die Nachteile dieses Verfahrens sind: erstens die kleine Produktivität, da man nur mit einem Spinnabzug von 800 m/min arbeitet, und zweitens, daß man auf einer Doppelspinnposition nur ein einziges Garn herstellt.The co-spinning of synthetic threads from two different polymers is known. US Pat. No. 4,025,595 relates to a process for producing mixed filaments with 20 to 68 fibrils and a titer between 70 and 260 den, wherein at least two fiber bundles are co-spun, swirled separately, stretched together and then at a degree of swirling between 45 and swirled 80%. According to this method, fully drawn threads are produced on a double spinning position. The disadvantages of this process are: firstly, the low productivity, since one only works with a spinning take-off of 800 m / min, and secondly, that only one yarn is produced in a double spinning position.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Verfügung zu stellen, das eine höhere Produktivität mit einem kleineren finanziellen Aufwand pro Spinnstelle erlaubt.The invention has for its object to provide a method that allows higher productivity with less financial effort per spinning station.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß auf einer ersten Spinnposition ein Polymer A und auf einer zweiten Spinnposition ein Polymer B zu wenigstens zwei Teilfäden versponnen, jeder der Teilfäden einer getrennten Behandlung unterworfen, je ein Teilfaden der beiden Spinnpositionen in einem Vereinigungspunkt zusammengefaßt und die resultierenden Fäder aufgewickelt werden.The object is achieved according to the invention in that a polymer A is spun in a first spinning position and a polymer B in a second spinning position to at least two partial threads, each of the partial threads is subjected to a separate treatment, a partial thread of the two spinning positions is combined in a union point and the resulting ones Threads are wound up.
Gemäß diesem Verfahren stellt man vorzugsweise schnellgesponnene Garne ohne Verstreckung vor der Aufwicklung her. Der schnellgesponnene Faden ist teilverstreckt und muß im Falle einer Verwendung für die Texturierung strecktexturiert werden. Ein teilverstrecktes Garn hat als Vorlagegarn bessere Eigenschaften für die Texturierung als ein vollverstrecktes Garn. Das erfindungsgemäße Garn ist aber auch als glattes oder verstrecktes Garn verwendbar.According to this process, preferably spun yarns are produced without drawing before winding. The fast spun thread is partially drawn and, if used for texturing, must be textured for drawing. A partially drawn yarn has better properties for texturing than a fully drawn yarn. The yarn according to the invention can also be used as a smooth or drawn yarn.
Wenn man zwei Teilfäden produzieren will, verwendet man eine einzige Spinndüse mit einer Halbkreisanordnung für die Kapillaren. Vorzugsweise stellt man pro Spinnposition vier bis acht Teilfäden her. In diesem Fall verwendet man zwei bis vier Spinndüsen, die nebeneinander angeordnet sind, d. h. die vier, sechs oder acht Spinndüsen auf einer gleichen Linie, oder die Spinndüsen einer Spinnposition auf einer gegenüber den Spinndüsen der anderen Spinnposition versetzten Linie.If you want to produce two threads, use a single spinneret with a semicircular arrangement for the capillaries. Preferably, four to eight partial threads are produced per spinning position. In this case two to four spinnerets are used, which are arranged side by side, i. H. the four, six or eight spinnerets on the same line, or the spinnerets of one spinning position on a line offset from the spinning nozzles of the other spinning position.
Gegenüber dem US-Patent 4 025 595 sind die erfindungsgemäß co-gesponnenen Fäden nur einmal und zwar zwischen dem Vereinigungspunkt und dem Aufwickeln verwirbelt.Compared to US Pat. No. 4,025,595, the threads co-spun according to the invention are only once swirled, namely between the point of union and the winding.
Obwohl der Titer des Endfadens nicht kritisch ist, stellt man Fäden mit einem Endtiter zwischen 50 und 600 dtex, vorzugsweise zwischen 50 und 260 dtex, her. Ebenfalls ist der Titer der Einzelfilamente unkritisch.Although the titer of the final thread is not critical, threads with a final titer between 50 and 600 dtex, preferably between 50 and 260 dtex, are produced. The titer of the individual filaments is also not critical.
Die erhaltenen Fäden sind LOY (Low-Oriented-Yarn) oder POY (Partially-Oriented-Yarn), vorzugsweise POY, mit einer Aufwickelgeschwindigkeit zwischen 2500 und 6000 m/min hergestellt. Die Teilfäden werden vorzugsweise auf zwei Aufspuleinrichtungen aufgewickelt.The threads obtained are LOY (Low Oriented Yarn) or POY (Partially Oriented Yarn), preferably POY, with a winding speed between 2500 and 6000 m / min. The partial threads are preferably wound on two winding devices.
Die verwendeten synthetischen Polymere sind reine oder modifizierte Polyester und/oder Polyamide und/oder Polypropylene oder ihre Copolymere. Als Polyamide kommen sowohl Polyamid 6 als auch Polyamid 66 oder ihre Copolymere in Frage. Unter Polyester versteht man Polyester hergestellt entweder durch Direktkondensation von Ethylenglykol und Terephthalsäure oder durch Umesterung von Dimethylterephthalat mit Ethylenglykol und anschließender Polykondensation des zunächst gebildeten Diglykolterephthalates. An Stelle von Ethylenglykol können noch andere Diole wie 1,3-Propandiol, 1,4-Butandiol, 1,6-Hexandiol oder Cyclohexan-Dimethanol, und neben der Terephthalsäure resp. des Dimethylterephthalates noch andere Dicarbonsäuren wie Isophthalsäure, Adipinsäure, Azelainsäure, Dimerfettsäure resp. die Alkylester dieser Säuren zusätzlich eingesetzt werden.The synthetic polymers used are pure or modified polyesters and / or polyamides and / or polypropylenes or their copolymers. Both polyamide 6 and polyamide 66 or their copolymers are suitable as polyamides. Polyester is understood to mean polyester produced either by direct condensation of ethylene glycol and terephthalic acid or by transesterification of dimethyl terephthalate with ethylene glycol and subsequent polycondensation of the diglycol terephthalate initially formed. Instead of ethylene glycol, other diols such as 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol or cyclohexane-dimethanol, and in addition to terephthalic acid or. of the dimethyl terephthalate still other dicarboxylic acids such as isophthalic acid, adipic acid, azelaic acid, dimer fatty acid or. the alkyl esters of these acids can also be used.
Als synthetische Polymere der Teilfäden können sowohl Polyester-Polyester-, Polyamid-Polyamid-, Polypropylen-Polypropylen- als auch Polyamid-Polyester-, Polyamid-Polypropylen, Polyester-Polypropylen-Kombinationen in Betracht gezogen werden. Man kann auch Kombinationen wählen, bei denen zwischen beiden Teilfäden eine gewiße Schrumpfdifferenz existiert.Both polyester-polyester, polyamide-polyamide, polypropylene-polypropylene and polyamide-polyester, polyamide-polypropylene, polyester-polypropylene combinations can be considered as synthetic polymers of the partial threads. Combinations can also be selected in which there is a certain shrinkage difference between the two threads.
Erfindungsgemäß kann man auch Vorlagefäden für Spun-like-Fäden herstellen. In diesem Fall kombiniert man beispielsweise modifizierte, d. h. regular- und basisch-färbbare Polyester. Der basisch färbbare Polyester enthält ein Metallsulfonat wie das Sulfonat der 3,5-Isophthalsäure oder das Sulfonat des 3,5-Isophthalsäure-Dimethylesters. Es ist auch möglich, einen modifizierten, basisch färbbaren Polyester einzusetzen. In diesem Fall enthält er zusätzlich ein Polyalkylenglykol oder ein Polyolefin, wie in der internationalen Anmeldung PCT/CH83/00035 beschrieben.According to the invention, it is also possible to produce master threads for spun-like threads. In this case, one combines, for example, modified, i.e. H. regular and basic dyeable polyester. The basic dyeable polyester contains a metal sulfonate such as the sulfonate of 3,5-isophthalic acid or the sulfonate of 3,5-isophthalic acid dimethyl ester. It is also possible to use a modified, basic dyeable polyester. In this case, it additionally contains a polyalkylene glycol or a polyolefin, as described in the international application PCT / CH83 / 00035.
Der Spun-like-Faden gemäß EP-Patent 22 065 ist auch gemäß der vorliegenden Erfindung herstellbar. Eine Spinnposition enthält dann Spinndüsen mit feinen und gröberen Kapillaren. Dieser Teilfaden bildet die Umhüllungskomponente und derjenige der anderen Spinnposition die Kernkomponente. Im Falle einer Herstellung von Spun-like-Fäden ist das titerbezogene Streckkraftverhältnis der Teilfäden aus verschiedenen Polymeren bei einer Bezugsverstreckung zwischen 1 : 1,2 und 1 : 2 größer als 2.The spun-like thread according to
Erfindungsgemäß ist bei der Behandlung der Teilfäden aus verschiedenen Polymeren die Einspannlänge im Blasschacht separat variierbar. Die Blaslufttemperatur, der Blasluftdruck und die Blasluftfeuchtigkeit sind bekannterweise einzustellen und können ebenfalls wie auch Spinnpräparationstyp und -auftragshöhe separat variiert werden.According to the invention, the clamping length in the blow shaft can be varied separately when treating the partial threads made of different polymers. The blown air temperature, the blown air pressure and the blown air humidity are known to be set and, like the spin preparation type and application amount, can also be varied separately.
Die Erfindung betrifft weiter eine Vorrichtung zur Durchführung des Verfahrens, dadurch gekennzeichnet, daß der Spinnposition für das Polymer (A) eine Dosierpumpe und wenigstens je eine Spinndüse und der Spinnposition für das Polymer (B) eine Dosierpumpe und wenigstens je eine Spinndüse zugeordnet sind und wenigstens je ein Konvergenzfadenführer und je eine Öse als ein Mittel zur Vereinigung für wenigstens je zwei Teilfäden sowie ein Aufspulmittel angeordnet sind.The invention further relates to a device for performing the method, characterized in that the spinning position for the polymer (A) is assigned a metering pump and at least one spinneret each and the spinning position for the polymer (B) is associated with a metering pump and at least one spinneret each and at least one convergence thread guide and one eyelet each are arranged as a means for merging for at least two part threads as well as a winding means.
Das Mittel zur Vereinigung der Teilfäden ist eine Öse, ein Stift oder ein Sauschwänzchen. Die erfindungsgemäße Vorrichtung enthält vorzugsweise zwei bis vier Spinndüsen pro Spinnposition. Die Vorrichtung könnte mehr als vier Spinndüsen aufweisen, was den Aufwand pro Spinnstelle noch reduzieren würde.The means to unite the partial threads is an eyelet, a pin or a swab tail. The device according to the invention preferably contains two to four spinnerets per spinning position. The device could have more than four spinnerets, which would further reduce the effort per spinning station.

Es ist aber durchaus möglich, diese Zahl bis drei oder vier zu variieren.The number of filaments emerging from each spinneret is not critical: it is preferably two, since this arrangement is the best known. However, it is quite possible to vary this number up to three or four.

Die Länge des Blasschachtes für diese Behandlung liegt z. B. zwischen 1 und 2 m.As mentioned above, each spinning position has a separate cooling treatment. The clamping length of each cooling treatment can be varied separately in order to achieve certain thread properties. The length of the blow duct for this treatment is e.g. B. between 1 and 2 m.
