Abstract

A solution spinning process for the production of a textile fiber with permanent repellent action includes the steps of preparing a spinnable polymer component and an ambivalent polymer compound which contains a repelling group and a residual group with an affinity for the spinnable polymer component, mixing the ambivalent polymer compound with the spinnable polymer component in a solvent, and spinning the mixture into a fiber, wherein the repelling groups orient themselves in the direction of the surface of the forming fiber and migrate to the surface, while the affine residual groups anchor the ambivalent polymer compound in the spinnable polymer compound as the solvent is driven off.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Textilfaser, welche eine permanente Phobierwirkung aufweist.The invention relates to a method for producing a textile fiber, which has a permanent phobic effect.

Textilmaterialien mit Phobiereigenschaften, insbesondere zur Abweisung von Öl, Wasser und Schmutz sind aus dem Stand der Technik bekannt. So ist in der EP 0 377 813 ein Verdeckstoff für Kraftfahrzeuge beschrieben, wo zur Erzielung der Phobiereigenschaften das Obergewebe mit einem Phobiermittel, hier ein Polymer auf Basis von Fluorpolymeren, ausgerüstet wird. Weiterhin bekannt sind Fluorwachse, z.B. Imprägniersprays für Bekleidungstextilien, die auf die Faseroberfläche aufgesprüht werden. Nachteilig ist jedoch, dass diese Phobiermittel mit der Zeit wieder abgetragen werden, da sie keine dauerhafte feste Verbindung zur Faseroberfläche besitzen. Textile materials having phobic properties, in particular for repelling oil, Water and dirt are known in the art. So in EP 0 377 813 a top material for motor vehicles described where to achieve the Phobiereigenschaften the upper fabric with a repellent, here a polymer Basis of fluoropolymers, is equipped. Also known are fluorine waxes, e.g. Impregnating sprays for clothing textiles which are on the fiber surface be sprayed on. The disadvantage, however, is that these phobizers with time be removed again, as they do not have a permanent solid connection to Own fiber surface.

Bekannte verbesserte Fluorcarbon-Systeme als Phobiermittel sind mit Harzgruppen (Melaminharze, Polyisocyanate) versehen, welche mit sich selbst vernetzen können. Dies führt dazu, dass nach der Beschichtung der Faser mit diesen Fluorcarbonen die Faser von einem aus den Harzgruppen gebildeten Netz eingehüllt wird (siehe Fig. 3). Die Fluorcarbongruppen ragen aus diesem Netz heraus und entfalten ihre abstoßende Wirkung z.B. gegen Wasser oder Schmutz. Derartige Fluorcarbone kommen beispielsweise bei Autoverdeckstoffen zum Einsatz und haben sich durchaus bewährt. Nachteilig ist, dass der beschriebene Phobiereffekt beim Gebrauch der Autoverdeckstoffe, z.B. durch Abtrieb bei Fahrtwind, durch Friktion von Staub, durch Faltvorgänge und andere Umwelteinwirkungen gemindert wird oder gänzlich verloren geht. Das die Faser umhüllende Netz kann nämlich durch die beschriebenen Einflüsse aufreißen. Damit löst sich das Phobiermittelsystem teilweise sogar großflächig vom Faserprodukt ab. Dies führt auch zu einer verstärkten Schmutzanhaftung und damit zu einem unschönen Aussehen des Verdeckstoffs. Das wird derzeit insbesondere dadurch überdeckt, dass nur dunkle Verdeckstoffe Anwendung finden. Gewünscht sind jedoch gerade in diesem Anwendungsbereich farbige Faserprodukte, passend zur Lackfarbe eines Kraftfahrzeuges.Known improved fluorocarbon systems as repellents are with resin groups (Melamine resins, polyisocyanates) provided, which can crosslink with itself. This results in that after coating the fiber with these fluorocarbons the Fiber is wrapped by a network formed from the resin groups (see Fig. 3). The fluorocarbon groups protrude from this network and unfold their repulsive Effect e.g. against water or dirt. Such fluorocarbons come for example, used for car roofing materials and have quite proven. The disadvantage is that the described Phobiereffekt when using the Car covers, e.g. by downforce at wind, by friction of dust, is mitigated by folding and other environmental effects or entirely get lost. Namely, the network enveloping the fiber can be characterized by the described Tearing in influences. In some cases, the repellent system even dissolves over a large area of the fiber product. This also leads to a reinforced Dirt attachment and thus to an ugly appearance of the top fabric. The is currently covered in particular by the fact that only dark cloths Find application. However, what is desired are precisely in this area of application colored fiber products, suitable for the paint color of a motor vehicle.

Des Weiteren wird in der US 6,063,474 eine thermoplastische Faser, insbesondere Polyolefinfaser beschrieben, wobei in die Polyolefinschmelze vor der Schmelzextrusion Fluorcarbonester eingebracht wird. Diese eingelagerten Fluorcarbonester können, wenn es ihre Natur erlaubt, sich an der Oberfläche konzentrieren und damit Phobierwirkungen entfalten. Da sowohl die Fluorcarbongruppe als auch die zum Ester zugehörige Kohlenwasserstoffgruppe keine Verbindung mit der Thermoplastfaser eingeht, wird das Phobiermittel in diesem Fall ebenso rein mechanisch in der Fasermasse gehalten. Eine dauerhafte Phobierwirkung ist nicht zu erwarten.Furthermore, in US 6,063,474 a thermoplastic fiber, in particular Polyolefinfaser, wherein in the polyolefin melt before the Melt extrusion Fluorcarbonester is introduced. This stored Fluorocarbon esters, if their nature permits, can be found on the surface concentrate and thereby unfold phobic effects. Because both the Fluorocarbon group as well as the ester group associated hydrocarbon group no connection with the thermoplastic fiber, the lotion is in this case also held purely mechanically in the pulp. A permanent one Phobierwirkung is not expected.

Das Dokument WO 95/01 396 beschreibt eine Schmelzextrusion von Polymerzusammensetzungen. Diese Polymerzusammensetzungen bestehen aus einer Mischung einer verspinnbaren Komponente (Polypropylen, Polyäthylen, Polyamid, Polyester) und einem Fluorcarbon. Das entstehende Produkt dieser Schmelzextrusion besitzt permanente Phobierwirkung. Das Dokument WO 99/05 345 offenbart des Weiteren ein Verfahren zur Herstellung von Textilfasern, bei dem eine fluorhaltige Weiteren ein Verfahren zur Herstellung von Textilfasern, bei dem eine fluorhaltige Verbindung und ein Polymer in einem Lösungsmittel vermischt werden. Die Mischung wird anschließend getrocknet und dann zu einer Faser extrudiert. Auch diese Faser hat eine permanente Phobierwirkung. Nachteilig bei der verwendeten Schmelzextrusion ist, dass die Fluorcarbonkomponente aufgrund der homogenen Verteilung in der Schmelze auch in der entstehenden Faser gleichmäßig über den Querschnitt verteilt vorliegt und nur der Anteil der Fluorcarbone, die sich an der Oberfläche befinden, zur Phobierwirkung beiträgt. Des Weiteren ist die Schmelzextrusuion auch nicht auf alle verspinnbaren Polymere anwendbar. Eine Polyacrylnitrilfaser lässt sich durch Schmelzextrusion nicht herstellen.The document WO 95/01 396 describes a melt extrusion of Polymer compositions. These polymer compositions consist of a Mixture of a spinnable component (polypropylene, polyethylene, polyamide, Polyester) and a fluorocarbon. The resulting product of this melt extrusion has permanent phobic effect. The document WO 99/05 345 discloses the Further, a process for the production of textile fibers, wherein a fluorine-containing Further, a process for the production of textile fibers, wherein a fluorine-containing Compound and a polymer are mixed in a solvent. The Mixture is then dried and then extruded into a fiber. Also This fiber has a permanent phobic effect. Disadvantageous in the used Melt extrusion is that the fluorocarbon component due to the homogeneous Distribution in the melt even in the resulting fiber evenly over the Distributed cross-section and only the proportion of fluorocarbons, located at the Surface, contributes to the Phobierwirkung. Furthermore, the Schmelzextrusuion not applicable to all spinnable polymers. A Polyacrylonitrile fiber can not be produced by melt extrusion.

Aufgabe der vorliegenden Erfindung ist ein Herstellungsverfahren für eine Textilfaser, bei der eine dauerhafte Phobierwirkung erzielt wird.The object of the present invention is a production method for a Textile fiber, in which a lasting Phobierwirkung is achieved.

Diese Aufgabe wird durch ein Verfahren zur Herstellung einer Textilfaser gemäß Anspruch 1 erzielt. Wesentliches Merkmal der durch die Erfindung hergestellten Textilfaser ist die ambivalente Polymerkomponente, die aus zwei unterschiedlichen Gruppen zusammengesetzt ist, einerseits der Phobiergruppe und andererseits der zur Fasermatrix hin affinen Restgruppe.This object is achieved by a method of producing a textile fiber according to Claim 1 achieved. Essential feature of the invention produced by Textile fiber is the ambivalent polymer component, which consists of two different Groups, on the one hand the Phobiergruppe and on the other hand the zur Fiber matrix towards affine residual group.

Im Gegensatz zu dem bekannten oben beschriebenen substantiven Systemen, die an der Faseroberfläche aufliegen, ist die Phobiergruppe in diesem Fall über die affine Restgruppe mit dem Faserpolymer verbunden. Ein Abrieb der Phobiergruppe ist kaum möglich, da gleichzeitig die affine Restgruppe aus dem Faserpolymerverbund herausgerissen werden müsste. Weitere Vorteile und Merkmale sind den Unteransprüchen zu entnehmen.In contrast to the known substantive systems described above In the case of the fiber surface, the phobier group in this case is the affine one Remaining group connected to the fiber polymer. An attrition of the phobia group is Hardly possible, because at the same time the affine residual group from the fiber polymer composite would have to be torn out. Other advantages and features are the Subclaims refer.

Als Phobiergruppen sind insbesondere Fluorcarbongruppen vorgesehen, es sind jedoch auch Silikon-Polymere denkbar.As Phobiergruppen particular fluorocarbon groups are provided, there are however, silicone polymers are also conceivable.

Die affine Restgruppen sind Gruppen, die eine deutliche Affinität zu dem Faserpolymer aufweisen, soll beispielsweise eine Polyacrylnitrilfaser hergestellt werden, werden ambivalente Polymerkomponenten mit Nitrilgruppen als affine Restgruppen bevorzugt. Bei der Verwendung anderer Faserpolymere (Polyamiden, Polyacrylaten, u.a.) wären entsprechend der chemischen Struktur des Faserpolymers die affinen Restgruppen für die ambivalente Polymerkomponente auszuwählen.The affine residue groups are groups that have a marked affinity to the Have fiber polymer to produce, for example, a polyacrylonitrile fiber become ambivalent polymer components with nitrile groups as affine Residual groups are preferred. When using other fiber polymers (polyamides, Polyacrylates, etc.) would be according to the chemical structure of the fiber polymer select the affinity residual groups for the ambivalent polymer component.

Eine Zusammensetzung aus einer verspinnbaren Polymerkomponente und einer ambivalenten Polymerverbindung, wobei die affine Restgruppe der ambivalenten Polymerverbindung eine Affinität zur verspinnbaren Polymerkomponente aufweist, kann zur Herstellung von Textilfasermaterial, wie beispielsweise Monofilamenten, Multifilamenten, Fasern, Garne oder Flächengebilde verwendet werden. Dies wird im Folgenden anhand eines Ausführungsbeispiels beschrieben. Es zeigen:

A composition of a spinnable polymer component and an ambivalent polymer compound wherein the affinity residual group of the ambivalent polymer compound has an affinity for the spinnable polymer component can be used to make textile fiber material such as monofilaments, multifilaments, fibers, yarns, or sheets. This will be described below with reference to an embodiment. Show it:

Die Fig. 1a zeigt eine Zusammensetzung. Die zwei bereitgestellten wesentlichen Komponenten zur Herstellung einer Textilfaser mit permanenter Phobierwirkung, nämlich die verspinnbare Polymerkomponente 1 und die ambivalente Polymerverbindung 2 werden vermischt. Die ambivalente Polymerverbindung 2 weist zwei unterschiedliche Gruppen auf, einerseits die Fluor enthaltende Polymerkette als Phobiergruppe 2.1, beispielsweise Polytretafluorethylen und andererseits besitzt die ambivalente Polymerverbindung 2 am anderen Ende eine affine Restgruppe 2.2. Diese affine Restgruppe 2.2 hat die Fähigkeit in Wechselwirkung mit dem Faserpolymer 1 zu treten. Als Faserpolymer 1 ist in Fig. 1a Polyacrylnitril vorgesehen und als affine Restgruppe 2.2 ein Kohlenwasserstoff mit Nitrilgruppen. Beide Polymerkomponenten 1 und 2 sind im vorliegenden Beispiel in einem Lösungsmittel 3, insbesondere einem Polyalkohol, wie beispielsweise Polyetherglykol gelöst. Der Anteil der Polymerkomponenten 1 und 2 im Lösungsmittel beträgt ca. 20 bis 30 Gew%. Nach dem Mischen der Komponenten 1 und 2 erfolgt das Ausspinnen des Gemischs, wobei das Lösungsmittel ausgetrieben wird. Die Phobiergruppen 2.1, die vom Faserpolymer 1 abgestoßen werden, orientieren sich bereits in Pfeilrichtung 4, d.h. in Richtung Faseroberfläche (Fig. 1b). Die Restgruppen 2.2 verlangsamen diesen Prozess aufgrund ihrer Affinität zum Faserpolymer 1. In Fig. 1c ist die ausgesponnene Faser zu sehen. Die Phobiergruppen 2.1 ragen aus der Oberfläche 5 der Faser 6 heraus. Zwischen dem Faserpolymer 1, dem Polyacrylnitril und den Nitrilgruppen der affinen Restgruppe 2.2 bestehen van der Waal'sche-Wechselwirkungen, wodurch die ambivalente Polymerverbindung 2 im Faserverbund gehalten wird. Abhängig vom Gewichtsanteil der Polymerverbindung 2 in der Faser 6, bevorzugt werden 10 bis 15 Gew%, können sich natürlich auch noch Polymerverbindungen 2 innerhalb der Faser befinden, wie dies in Fig. 2 angedeutet ist. Diese können erst an die Oberfläche 5 nachrücken, wenn an der Oberfläche 5 ein Platz frei ist.
Auch wenn dies aus den Figuren nicht so deutlich wird, die Faser 6 weist umfangseitig, d.h. auf ihrer gesamten Oberfläche 5, Polymergruppen 2.2 mit Phobiereigenschaften auf. Fig. 1a shows a composition. The two essential components provided for the production of a textile fiber with permanent repellent effect, namely the spinnable polymer component 1 and the ambivalent polymer compound 2 are mixed. The ambivalent polymer compound 2 has two different groups, on the one hand the fluorine-containing polymer chain as Phobiergruppe 2.1, for example Polytretafluorethylen and on the other hand, the ambivalent polymer compound 2 has an affine residual group 2.2 at the other end. This affine residual group 2.2 has the ability to interact with the fiber polymer 1. As fiber polymer 1, polyacrylonitrile is provided in FIG. 1 a and, as affine residual group 2.2, a hydrocarbon containing nitrile groups. Both polymer components 1 and 2 are dissolved in the present example in a solvent 3, in particular a polyalcohol, such as polyether glycol. The proportion of polymer components 1 and 2 in the solvent is about 20 to 30% by weight. After mixing the components 1 and 2, the spinning out of the mixture, the solvent is expelled. The Phobiergruppen 2.1, which are repelled by the fiber polymer 1, are already oriented in the direction of arrow 4, ie in the direction of the fiber surface (Fig. 1b). The residual groups 2.2 slow this process down due to its affinity for the fiber polymer 1. In Fig. 1c the spun fiber is seen. The Phobiergruppen 2.1 protrude from the surface 5 of the fiber 6 out. Between the fiber polymer 1, the polyacrylonitrile and the nitrile groups of the affine residual group 2.2 exist van der Waal'sche interactions, whereby the ambivalent polymer compound 2 is held in the fiber composite. Depending on the proportion by weight of the polymer compound 2 in the fiber 6, preferably 10 to 15% by weight, of course, polymer compounds 2 can also be located inside the fiber, as indicated in FIG. 2. These can only move up to the surface 5, if at the surface 5 a place is free.
Although this is not so clear from the figures, the fiber 6 has peripherally, ie on its entire surface 5, polymer groups 2.2 with lapping properties.

Vergleicht man nun diese erfindungsgemäß hergestellte Faser aus Fig. 2 mit dem Stand der Technik, dargestellt in Fig. 3, so wird der wesentliche Unterschied deutlich. Auch bei der bekannten phobierten Faser ragen Fluorcarbone 7.1 von der Oberfläche 5 der Faser 1 ab und entfalten die Phobierwirkung. Endständig befinden sich jedoch keine Gruppen, die in der Fasermasse gehalten werden, sondern eine Harzkomponente 7.2, die mit sich selbst reagiert und das die Faser 6 umspannende Netz 8 bildet. Durch äußere Einflüsse ist es möglich die Polymerverbindung 7 mit der Phobiergruppe 7.1 aus dem Netz herauszulösen, oder gar Teile des Netzes von der Faser abzureißen. Die Faser ist an diesen Stellen dann ferner schmutzanfällig.If one then compares this fiber produced according to the invention from FIG. 2 with the state of the art Technology, shown in Fig. 3, the essential difference becomes clear. Also In the known phobized fiber, fluorocarbons 7.1 protrude from the surface 5 of the Fiber 1 and unfold the Phobierwirkung. However, none are terminal Groups held in the pulp but a resin component 7.2, which reacts with itself and forms the fiber 6 spanning network 8. By external influences, it is possible the polymer compound 7 with the phobier 7.1 Remove from the network, or even tear off parts of the network of the fiber. The Fiber is then dirt-prone at these locations.

Bei der erfindungsgemäßehergestellte Faser 6 (Fig. 2) ist dies nicht und schon gar nicht in diesem Ausmaß möglich, da die ambivalente Polymerverbindung 2 über die Gruppen 2.2 mit der Fasermasse 1 verbunden ist.In the case of the fiber 6 (FIG. 2) produced according to the invention, this is not and certainly not at all this extent possible because the ambivalent polymer compound 2 via the groups 2.2 is connected to the fiber mass 1.

Die zur Herstellung der Textilfasern eingesetzten Zusammensetzungen aus Polymerkomponente 1 und ambivalenter Polymerverbindung 2 können je nach Einsatzgebiet der Fasern weitere Additive enthalten. Bei Bekleidungstextilien und Stoffen für die Kraftfahrzeugindustrie sind ferner farbige Fasern gewünscht. Der Zusammensetzung werden in solchen Fällen entsprechende Farbpigmente zugemischt. Für andere Anwendungen sind Beimischungen von Stabilisatoren, Quencher, Gleitmitteln oder keramische bzw. metallische Verstärkungsfasern denkbar. The compositions used to prepare the textile fibers Polymer component 1 and ambivalent polymer compound 2 may vary depending on Field of application of the fibers contain further additives. For apparel textiles and Fabrics for the automotive industry also colored fibers are desired. Of the Composition will be appropriate in such cases Mixed with color pigments. For other applications, admixtures of Stabilizers, quenchers, lubricants or ceramic or metallic Reinforcing fibers conceivable.
