Abstract
Description
Die Erfindung betrifft die Verwendung von Triacetin in textilen Gleitmitteln und ein Verfahren zur Reduzierung der Viskosität textiler Gleitmittel.The invention relates to the use of triacetin in textile lubricants and a method for reducing the viscosity of textile lubricants.
Bei der Herstellung von synthetischen Fasermaterialien wird unmittelbar nach der Bildung der Filamente die Oberfläche der Fäden mit sogenannten Faserpräparationen behandelt ("Chemiefasern/Textil-Industrie" 1977, 328 - 335). Es ist allgemein bekannt, daß ohne eine solche Präparierung Synthesefasern weder hergestellt noch in der textilen Weiterverarbeitung verwendet werden können. Das Aufbringen eines Glättemittels ist notwendig, weil die ursprüngliche Oberfläche der meisten polymeren Fasermaterialien hohe Reibungskräfte verursacht, so daß durch die ständigen Kontakte mit beispielsweise Leitorganen während der Herstellungs- und Verarbeitungsprozesse ein Abscheuern der Fasern erfolgt, was letztlich zu Filament- oder Garnbrüchen führen kann. Des weiteren nehmen polymere Filamentmaterialien im allgemeinen nur wenig Wasser auf. Sie neigen daher dazu, zu isolieren und elektrische Aufladungen hervorzurufen. Selbst wenn die Fasern mit einem Glättemittel versehen sind, können trotzdem noch durch Reibung elektrostatische Aufladungen entstehen und das Abstoßen eines Filaments vom anderen kann den Verarbeitungsprozeß erschweren, wenn nicht sogar unmöglich machen.In the production of synthetic fiber materials, the surface of the threads is treated with so-called fiber preparations immediately after the formation of the filaments ("Chemical fibers / textile industry" 1977, 328-335). It is generally known that synthetic fibers can neither be produced nor used in further textile processing without such a preparation. The application of a smoothing agent is necessary because the original surface of most polymeric fiber materials causes high frictional forces, so that the fibers are rubbed off due to the constant contact with, for example, guide elements during the manufacturing and processing processes, which can ultimately lead to filament or yarn breaks. Furthermore, polymeric filament materials generally absorb little water. They therefore tend to isolate and electrical charges to evoke. Even if the fibers are provided with a smoothing agent, electrostatic charges can still arise due to friction and the repulsion of one filament from the other can make the processing process difficult, if not impossible.
Schmälzen sollen eine optimale Garnherstellung aus losen oder vorgeordneten Fasermaterialien gewährleisten und müssen daher insbesondere die Haft- und Gleiteigenschaften von Synthesestapelfasern, Naturfasern und/oder Mischungen von natürlichen und synthetischen Fasermaterialien verbessern (Chwala/Anger: "Handbuch der Textilhilfsmittel", Kap. 3.7, Verlag Chemie, Weinheim 1977).Melting should ensure optimal yarn production from loose or upstream fiber materials and must therefore in particular improve the adhesive and sliding properties of synthetic staple fibers, natural fibers and / or mixtures of natural and synthetic fiber materials (Chwala / Anger: "Handbuch der Textilhilhilmittel", chapter 3.7, publisher Chemistry, Weinheim 1977).
Viele Faserpräparationen und Schmälzen, die als Hauptwirksubstanzen Glättemittel, Antistatika und/oder Emulgatoren enthalten, sind fest, pastös oder zähflüssig. Da aus verarbeitungstechnischen Gründen flüssigen Faserpräparationen und Schmälzen der Vorzug gegeben wird, werden Faserpräparationen und Schmälzen mit Stellmitteln (Verdünnungsmitteln) in eine flüssige Form überführt. Je höher der für die gewünschte Viskosität benötigte Gehalt an Stellmitteln ist, um so mehr nimmt jedoch die Wirksamkeit, insbesondere die Gleitmittelwirksamkeit, der Präparationen und Schmälzen ab. Üblicherweise werden als Stellmittel Glykole und/oder Alkylglykole eingesetzt eingesetzt, die jedoch hinsichtlich ihrer Toxikologie nicht unbedenklich sind.Many fiber preparations and lubricants, which contain smoothing agents, antistatic agents and / or emulsifiers as their main active substances, are solid, pasty or viscous. Since preference is given to liquid fiber preparations and slicing for processing reasons, fiber preparations and slicing are converted into a liquid form using adjusting agents (diluents). However, the higher the leveling agent content required for the desired viscosity, the more the effectiveness, in particular the effectiveness of the lubricant, of the preparations and lubricants decreases. Glycols and / or alkyl glycols are usually used as adjusting agents, but their toxicology is not harmless.
Aus der französischen Offenlegungsschrift FR-A-784966 ist es bekannt, cellulosehaltige Produkte mit Glycerinestern wie Triacetin zu behandeln, um den Produkten eine Appretur zu verleihen bzw. um einen Weichmacher-Effekt zu erzielen.From French published patent application FR-A-784966 it is known to treat cellulose-containing products with glycerol esters such as triacetin in order to impart a finish to the products or to achieve a plasticizer effect.
Die der Erfindung zugrundeliegende Aufgabe bestand daher in der Entwicklung von Faserpräparationen und Schmälzen, die eine für die Applikation geeignete Viskosität besitzen, die die Gelneigung von Faserpräparationen und Schmälzen verhindern, zumindest jedoch erheblich reduzieren und die Fasermaterialien ausgezeichnete Glätteeigenschaften und eine sehr gute Antistatik verleihen. Des weiteren wird an die zu entwickelnden Faserpräparationen und Schmälzen die Bedingung gestellt, physiologisch unbedenklich zu sein.The object on which the invention is based was therefore the development of fiber preparations and lubricants which have a viscosity suitable for the application, which prevent the tendency of fiber preparations and lubricants to curl, but at least considerably reduce them, and give the fiber materials excellent smoothness properties and very good antistatic properties. Furthermore the fiber preparations and lubricants to be developed are subject to the condition of being physiologically harmless.
Überraschenderweise wurde gefunden, daß die an die Faserpräparationen und Schmälzen gestellten hohen Anforderungen von triacetinhaltigen Faserpräparationen und Schmälzen erfüllt werden.Surprisingly, it was found that the high demands placed on the fiber preparations and slicing are met by fiber preparations and sizing containing triacetin.
Gegenstand der Erfindung ist dementsprechend die Verwendung von Triacetin in textilen Gleitmitteln auf Basis von Glättemitteln, Antistatika und/oder Emulgatoren.The invention accordingly relates to the use of triacetin in textile lubricants based on smoothing agents, antistatic agents and / or emulsifiers.
Weiterer Erfindungsgegenstand ist ein Verfahren zur Reduzierung der Viskosität textiler Gleitmittel, welches dadurch gekennzeichnet ist, daß textile Gleitmittel auf Basis von Glättemitteln, Antistatika und/oder Emulgatoren mit Triacetin vermischt werden.Another object of the invention is a method for reducing the viscosity of textile lubricants, which is characterized in that textile lubricants based on smoothing agents, antistatic agents and / or emulsifiers are mixed with triacetin.

Als Emulgatoren, Netzmittel und/oder Antistatika kommen anionische, kationische und/oder nichtionische Tenside in Betracht, wie Mono- und/oder Diglyceride, beispielsweise Glycerinmono-und/oder Glycerindioleat, alkoxylierte, vorzugsweise ethoxylierte und/oder propoxylierte Fette, Öle, Fettalkohole mit 8 bis 24 C-Atomen und/oder C₈₋₁₈-Alkylphenole, beispielsweise Rizinusöl mit 25 Mol Ethylenoxid (EO) und/oder C₁₆₋₁₈-Fettalkohol mit 8 Mol Propylenoxid und 6 Mol EO, gewünschtenfalls alkoxylierte C₈₋₂₄-Fettsäuremono- und/oder -diethanolamide, beispielsweise gegebenenfalls ethoxyliertes Ölsäuremono- und/oder -diethanolamid, Talgfettsäuremono- und/oder -diethanolamid und/oder Kokosfettsäuremono- und/oder diethanolamid, Alkali- und/oder Ammoniumsalze alkoxylierter, vorzugsweise ethoxylierter und/oder propoxylierter, gegebenenfalls endgruppenverschlossener C₈₋₂₂-Alkyl- und/oder C₈₋₂₂-Alkenylalkoholsulfonate, Umsetzungsprodukte aus gegebenenfalls alkoxylierten C₈₋₂₂-Alkylalkoholen mit Phosphorpentoxid oder Phosphoroxychlorid in Form ihrer Alkali-, Ammonium- und/oder Aminsalze, beispielsweise Phosphorsäureester von ethoxyliertem C12/14-Fettalkohol, neutralisiert mit Alkanolaminen, Alkali- und/oder Ammoniumsalze von C₈₋₂₂-Alkylsulfosuccinaten, beispielsweise Natriumdioctylsulfosuccinat und/oder Aminoxiden, beispielsweise Dimethyldodecylaminoxid. Bei dieser beispielhaften Aufzählung von Glättemitteln, Emulgatoren, Antistatika und/oder Netzmitteln muß berücksichtigt werden, daß eine Vielzahl der genannten Substanzen nicht nur eine Funktion, sondern mehrere Funktionen besitzen: Beispielsweise kann ein Glättemittel gleichzeitig auch als Antistatikum und/oder als Emulgator wirken.The textile lubricants can be used as smoothing agents, for example mineral oils, fatty acid esters with 8 to 22 carbon atoms in the fat residue and 1 to 22 carbon atoms in the alcohol residue, for example methyl palmitate, isobutyl stearate and / or 2-ethylhexyl tallow fatty acid, polyol carboxylic acid esters, for example coconut fatty acid esters of glycerol and / or alkoxylated glycerols, silicones, for example dimethylpolysiloxane and / or polyalkylene glycols, for example ethylene oxide / propylene oxide mixed polymers with average molecular weights between 600 and 6,000 (chemical fibers / textile industry 1977 335) included. Suitable emulsifiers, wetting agents and / or antistatic agents are anionic, cationic and / or nonionic surfactants, such as mono- and / or diglycerides, for example glycerol mono- and / or glycerol dioleate, alkoxylated, preferably ethoxylated and / or propoxylated fats, oils, fatty alcohols 8 to 24 carbon atoms and / or C₈₋₁₈ alkylphenols, for example castor oil with 25 moles of ethylene oxide (EO) and / or C₁₆₋₁₈ fatty alcohol with 8 moles of propylene oxide and 6 moles of EO, if desired alkoxylated C₈₋₂₄ fatty acid mono- and / or -diethanolamides, for example optionally ethoxylated oleic acid mono- and / or -diethanolamide, tallow fatty acid mono- and / or -diethanolamide and / or coconut fatty acid mono- and / or diethanolamide, alkali and / or ammonium salts of alkoxylated, preferably ethoxylated and / or propoxylated, optionally end-capped C₈₋₂₂-alkyl and / or C₈₋₂₂-alkenyl alcohol sulfonates, reaction products from optionally alkoxylated C₈₋₂₂ alkyl alcohols with phosphorus pentoxide or phosphorus oxychloride in the form of their alkali, ammonium and / or amine salts, for example phosphoric acid esters of ethoxylated C 12/14 fatty alcohol, neutralized with alkanolamines, alkali and / or ammonium salts of C₈₋₂₂ alkyl sulfosuccinates , for example sodium dioctyl sulfosuccinate and / or amine oxides, for example dimethyldodecylamine oxide. In this exemplary list of smoothing agents, emulsifiers, antistatic agents and / or wetting agents, it must be taken into account that a large number of the substances mentioned have not only one function, but several functions: for example, a smoothing agent can simultaneously act as an antistatic agent and / or as an emulsifier.
Als fakultative Bestandteile enthalten die triacetinhaltigen textilen Gleitmittel Fadenschlußmittel, z. B. Polyacrylate, Fettsäuresarcoside und/oder Mischpolymerisate mit Maleinsäureanhydrid (Melliand Textilberichte 1977, 197) und/oder Polyurethane gemäß DE-A-38 30 468, pH-Wert-Regulantien, beispielsweise C₁₋₄-Carbonsäuren und/oder C₁₋₄-Hydroxycarbonsäuren, wie Essigsäure und/oder Glykolsäure, Alkalihydroxide, wie Kaliumhydroxid und/oder Amine wie Triethanolamin, Bakterizide und/oder Korrosionsschutzmittel.The optional triacetin-containing textile lubricants contain thread closure agents, e.g. B. polyacrylates, fatty acid sarcosides and / or copolymers with Maleic anhydride (Melliand Textile Reports 1977 , 197) and / or polyurethanes according to DE-A-38 30 468, pH regulators, for example C₁₋₄-carboxylic acids and / or C₁₋₄-hydroxycarboxylic acids, such as acetic acid and / or glycolic acid, alkali metal hydroxides , such as potassium hydroxide and / or amines such as triethanolamine, bactericides and / or anti-corrosion agents.
Üblicherweise werden triacetinhaltige Schmälzen auf Synthesestapelfasern, Naturfasern oder Mischungen aus natürlichen und synthetischen Fasermaterialien aufgesprüht. Die Auftragsmenge der Schmälzen in unverdünnter Form oder in Mischung mit Wasser liegt zwischen 0,1 und 3 Gew.-%, bezogen auf das Gewicht der Fasermaterialien.Triacetin-containing melts are usually sprayed onto synthetic staple fibers, natural fibers or mixtures of natural and synthetic fiber materials. The quantity of melt applied in undiluted form or in a mixture with water is between 0.1 and 3% by weight, based on the weight of the fiber materials.
Die Applikation triacetinhaltiger Faserpräparationen erfolgt in bekannter Weise unmittelbar nach Austritt der Kapillaren aus der Spinndüse. Die Faserpräparationen, die eine Temperatur zwischen 18 und 60 °C haben, werden mit Hilfe von Auftragswalzen oder mittels Dosierpumpen über geeignete Applikatoren aufgebracht. Die Auftragsmenge der Faserpräparationen in unverdünnter Form oder in Form wäßriger Emulsionen liegt zwischen 0,3 und 2 Gew.-%, bezogen auf das Gewicht der Fadenbündel. Nach der Behandlung mit den Präparationen werden die Fadenbündel auf Spinnspulen aufgewickelt.Triacetin-containing fiber preparations are applied in a known manner immediately after the capillaries have emerged from the spinneret. The fiber preparations, which have a temperature between 18 and 60 ° C, are applied with the help of application rollers or with metering pumps using suitable applicators. The quantity of fiber preparations applied in undiluted form or in the form of aqueous emulsions is between 0.3 and 2% by weight, based on the weight of the thread bundle. After treatment with the preparations, the bundles of threads are wound on spinning bobbins.
Die wäßrigen Emulsionen triacetinhaltiger Faserpräparationen enthalten üblicherweise 5 bis 30 Gew.-% der unverdünnten Faserpräparation.The aqueous emulsions of triacetin-containing fiber preparations usually contain 5 to 30% by weight of the undiluted fiber preparation.
Aufgrund ihrer niedrigen Viskosität werden die erfindungsgemäßen Faserpräparationen vorzugsweise unverdünnt auf polymere Filamentmaterialien, beispielsweise Polypropylen-, Polyester-und/oder Polyamidfilamente appliziert.Because of their low viscosity, the fiber preparations according to the invention are preferably applied undiluted to polymeric filament materials, for example polypropylene, polyester and / or polyamide filaments.
Im Vergleich zu den bekannten, stellmittelhaltigen textilen Gleitmitteln hat die Verwendung von Triacetin als Stellmittel in textilen Gleitmitteln keinen negativen Einfluß auf die glättende und antistatische Wirksamkeit solcher textiler Gleitmittel. Ferner bewirkt Triacetin, das toxikologisch und ökologisch unbedenklich ist, eine deutliche Reduzierung der Gelneigung von textilen Gleitmitteln.In comparison to the known, lubricant-containing textile lubricants, the use of triacetin as a lubricant in textile lubricants has no negative influence on the smoothing and antistatic effectiveness of such textile lubricants. Triacetin, which is toxicologically and ecologically harmless, also significantly reduces the tendency of textile lubricants to gel.
