Abstract
Description
Die Erfindung betrifft polyurethanhaltige Spinnpräparationen, ein Verfahren zur Verbesserung des Fadenschlusses beim Schmelzspinnen synthetischer Fasermaterialien sowie die Verwendung von Polyurethan als FAdenschlußmittel in Spinnpräparationen.The invention relates to polyurethane-containing spin finishes, a method for improving thread closure during melt spinning synthetic fiber materials and the use of polyurethane as thread closure agent in spin finishes.
Beim Schmelzspinnen von synthetischen Fasermaterialien und deren Weiterverarbeitung zu textilen oder technischen Garnen werden die multifilen Fäden ohne Drehung auf die Spinnspule aufgewickelt. Die Einzelkapillaren liegen als parallele Fadenbündel vor, wobei der Zusammenhalt der Einzelkapillaren lediglich durch die mehr oder weniger stark ausgeprägte Adhäsionswirkung der Spinnpräparationen bewirkt wird. Bei dem anschließenden Streckprozeß erhalten diese Garne normalerweise einen Schutzdrall von einigen Drehungen pro Meter. Dieser Schutzdrall ist aber für viele nachfolgende Verarbeitungsprozesse nicht ausreichend. In vielen Fällen werden daher die Fäden in einem getrennten Verfahrensschritt gezwirnt. Das Zwirnen ist jedoch eine teure, zusätzliche Prozeßstufe. Um die Kosten des Zwirnens zu reduzieren, wurde bereits vorgeschlagen, die Fadenbündel mit Hilfe eines Luftstromes zu verwirbeln und gegebenenfalls anschließend zu zwirnen. Der Prozeß der Verwirbelung ist jedoch ebenfalls teuer und nur schwierig zu kontrollieren. Des weiteren wird der Verwirbelungsgrad reduziert, wenn das Garn unter Spannung über Fadenführer geleitet wird. Die Folge ist, daß es zu Knotenbildungen kommt, die das Aussehen der Gewebe negativ beeinflussen (US 4 632 874).When melt-spinning synthetic fiber materials and processing them into textile or technical yarns, the multifilament threads are wound onto the spinning bobbin without rotation. The individual capillaries are in the form of parallel bundles of threads, the cohesion of the individual capillaries only being brought about by the more or less pronounced adhesive effect of the spin finishes. In the subsequent stretching process, these yarns are usually given a protective twist of a few turns per meter. However, this protective twist is not sufficient for many subsequent processing processes. In many cases, the threads are therefore twisted in a separate process step. However, twisting is an expensive, additional process step. In order to reduce the cost of twisting, it has already been proposed to swirl the bundles of threads with the aid of an air stream and then, if necessary, to twist them. However, the swirling process is also expensive and difficult to control. Furthermore, the degree of intermingling is reduced if the yarn is passed under tension through the thread guide. The result is that it is too Knot formation occurs, which negatively affect the appearance of the tissues (US 4,632,874).
Eine andere Methode, das Kostenproblem zu lösen, ist die Verwendung von Fadenschlußmitteln in Spinnpräparationen. So werden beispielsweise in DE-OS 34 02 155 Epoxyalkylverbindungen als Fadenschlußmittel beschrieben. Nach dem Aufbringen solcher Spinnpräparationen auf die Fadenbündel ist jedoch eine Hitzebehandlung erforderlich. Des weiteren bewirken Epoxyalkylverbindungen einen permanenten Fadenschluß, der die Eigenschaften des fertigen Textils beeinflußt. In den meisten Fällen sollen jedoch Spinnpräparationen keinen Effekt auf der Faser hinterlassen und durch Auswaschen wieder leicht entfernt werden können (Chemiefasern/Textil-Industrie 1977, 328).Another method of solving the cost problem is to use thread closure agents in spin finishes. For example, DE-OS 34 02 155 describes epoxyalkyl compounds as thread-closing agents. However, heat treatment is required after applying such spin finishes to the bundles of threads. Epoxyalkyl compounds also cause permanent thread closure, which influences the properties of the finished textile. In most cases, however, spin finishes should not have any effect on the fiber and can be easily removed by washing them out (chemical fibers / textile industry 1977 , 328).
Aus US 3 505 220 sind Präparationsmittel bekannt, die Mineralöle, Polybutylene mit mittleren Molekulargewichten zwischen 150 und 750, Alkyl- oder Alkenylsäurephosphate mit 13 bis 19 C-Atomen in den Alkyl- oder Alkenylresten und oxidierte pflanzliche Öle enthalten. Die hohe Viskosität dieser Mittel führt jedoch zu Schwierigkeiten bei der Anwendung.From US 3,505,220 preparation agents are known which contain mineral oils, polybutylenes with average molecular weights between 150 and 750, alkyl or alkenyl acid phosphates with 13 to 19 carbon atoms in the alkyl or alkenyl radicals and oxidized vegetable oils. However, the high viscosity of these agents leads to difficulties in use.
Die Aufgabe der Erfindung bestand in der Entwicklung von Spinnpräparationen, die eine sehr gute Adhäsion der Einzelfäden eines Fadenbündels bewirken und die Verwirbelung und/oder das Zwirnen von Fadenbündeln überflüssig machen. Des weiteren sollen die Spinnpräparationen in einfacher Weise anwendbar sein und keine Thermobehandlung erfordern.The object of the invention was to develop spin finishes which bring about very good adhesion of the individual threads of a bundle of threads and make the intermingling and / or twisting of bundles of threads unnecessary. Furthermore, the spin finishes should be easy to use and require no thermal treatment.
Überraschenderweise wurde gefunden, daß diese hohen Anforderungen von polyurethanhaltigen Spinnpräparationen erfüllt werden.Surprisingly, it has been found that these high requirements are met by polyurethane-containing spin finishes.
Erfindungsgegenstand sind dementsprechend Spinnpräparationen auf Basis von Glättemitteln, Emulgatoren, Netzmitteln, Fadenschlußmitteln und/oder Antistatika, die dadurch gekennzeichnet sind, daß sie, bezogen auf Gesamtaktivsubstanzgehalt, 1 bis 40 Gew.-% Polyurethane enthalten.Accordingly, the subject of the invention are spin finishes based on smoothing agents, emulsifiers, wetting agents, thread-locking agents and / or antistatic agents, which are characterized in that they contain 1 to 40% by weight of polyurethanes, based on the total active substance content.
Weiterer Erfindungsgegenstand ist Verfahren zur Verbesserung des Fadenschlusses beim Schmelzspinnen synthetischer Fasermaterialien, welches dadurch gekennzeichnet ist, daß im Anschluß an das Schmelzspinnen, bezogen auf das Gewicht der Fadenbündel, 0,3 bis 2,0 Gew.-% polyurethanhaltiger Spinnpräparation-Aktivsubstanz auf die Fadenbündel aufgebracht werden.Another object of the invention is a method for improving the thread closure during melt spinning of synthetic fiber materials, which is characterized in that, after melt spinning, based on the weight of the thread bundle, 0.3 to 2.0% by weight of polyurethane-containing active spin finish on the thread bundle be applied.
Ferner ist die Verwendung von Polyurethanen als Fadenschlußmittel in Mengen von 1 bis 40 Gew.-%, bezogen auf Gesamtaktivsubstanzgehalt, in Spinnpräparationen Erfindungsgegenstand.The use of polyurethanes as thread-closing agents in amounts of 1 to 40% by weight, based on the total active substance content, in spin finishes is also an object of the invention.

Bezogen auf die Polyolkomponente liegt das OH/NCO-Äquivalentverhältnis zwischen 0,4 und 1,1, vorzugsweise zwischen 0,5 und 0,7. Nachdem die Mischung 1 bis 3 Stunden gegebenenfalls unter Rückfluß erhitzt wurde, wird auf 18 bis 30 °C abgekühlt und mit in organischen Lösungsmitteln gelösten tertiären Alkylaminen neutralisiert. Die Polyurethanmasse wird dann in Wasser dispergiert und anschließend, bezogen auf ein ursprüngliches NCO-Äquivalent, mit 0 bis 0,7 Äquivalenten Mono- und/oder Diaminen, gelöst in Wasser, umgesetzt. Nach Entfernen des Lösungsmittels mittels Destillation werden anionische Polyurethanedispersionen erhalten, die keine freien NCO-Funktionen mehr besitzen. Der Polyurethangehalt liegt in den Dispersionen zwischen 10 und 60 Gew.-%, vorzugsweise zwischen 25 und 40 Gew.-%.The polyurethanes to be used according to the invention are produced in a manner known per se (see, for example, in Ullmanns Encylcopädie der industrial chemistry, volume 19, pages 302 ff., Verlag Chemie (1980)) by polyisocyanates with polyols and hydroxycarboxylic acids in the presence of solvents and optionally catalysts can be converted into prepolymers in 1 to 6 hours at temperatures between 60 and 120 ° C. Based on the polyol component, the OH / NCO equivalent ratio is between 0.4 and 1.1, preferably between 0.5 and 0.7. After the mixture has been heated under reflux for 1 to 3 hours, the mixture is cooled to 18 to 30 ° C. and neutralized with tertiary alkylamines dissolved in organic solvents. The polyurethane mass is then dispersed in water and then, based on an original NCO equivalent, reacted with 0 to 0.7 equivalents of mono- and / or diamines, dissolved in water. After removing the Solvent by means of distillation gives anionic polyurethane dispersions which no longer have free NCO functions. The polyurethane content in the dispersions is between 10 and 60% by weight, preferably between 25 and 40% by weight.

Die Applikation polyurethanhaltiger Spinnpräparation-Emulsionen erfolgt in bekannter Weise nach Austritt der Kapillaren aus der Spinndüse. Die Präparationen, die eine Temperatur zwischen 18 und 30 °C haben, werden mit Hilfe von Auftragswalzen oder mittels Dosierpumpen über geeignete Applikatoren aufgebracht. Die Aktivsubstanzauftragsmenge der Spinnpräparation-Emulsionen, die gegebenenfalls mit Wasser auf einen Aktivsubstanzgehalt zwischen 3 und 20 Gew.-% verdünnt werden, beträgt etwa 0,3 bis 2,0 Gew.-%, bezogen auf das Gewicht der Fadenbündel. Nach der Behandlung mit den Präparationen werden die Fadenbündel auf Spinnspulen aufgewickelt. Es ist überraschend, daß die mit den erfindungsgemäßen Spinnpräparationen behandelten Fadenbündel neben einem verbesserten Fadenschluß reduzierte dynamische Faden/Festkörper-Reibungskoeffizienten besitzen. Die Fadenbündel können aus Polyamiden, Polyestern oder Polyolefinen bestehen.Spinning preparation emulsions containing polyurethane are applied in a known manner after the capillaries have emerged from the spinneret. The preparations, which have a temperature between 18 and 30 ° C, are applied with the help of application rollers or with metering pumps using suitable applicators. The amount of active substance applied to the spin finish emulsions, which are optionally diluted with water to an active substance content of between 3 and 20% by weight, is about 0.3 to 2.0% by weight, based on the weight of the thread bundle. After treatment with the preparations, the bundles of threads are wound on spinning bobbins. It is surprising that the thread bundles treated with the spin finishes according to the invention have, in addition to an improved thread closure, reduced dynamic thread / solid friction coefficients. The thread bundles can consist of polyamides, polyesters or polyolefins.
