Definitions
- the invention relates to aqueous emulsions for softening fiber material, in particular textile material.
- emulsifier or emulsifier system they contain unsymmetrical diesters of certain dicarboxylic acids selected as softening agents.
- These emulsions may additionally contain other soft-grip agents known for the treatment of fiber material, in particular polyethylene.
- a process for softening fiber material using these emulsions is also claimed.
- polyethylene emulsions belonging to the prior art still leave something to be desired, particularly with regard to the handle and the wet soiling.
- the object of the present invention is to provide plasticizer emulsions for fiber material, in particular textile material, which do not show the disadvantages shown when they are used.
- a method for softening fiber material, in particular textile material, with the emulsions according to the invention is also claimed.
- the diesters as dicarboxylic acid are based on succinic, glutaric, adipic and fumaric and in particular maleic acid.
- succinic, glutaric, adipic and fumaric and in particular maleic acid is particularly preferred for economic reasons, but in general the asymmetrical diesters can be produced particularly well from the anhydrides, which is why all acids forming an anhydride are of particular importance.
- One acid residue of the dicarboxylic acid is esterified with a monohydric alcohol having 12 to 28 carbon atoms.
- These alcohols can contain double bonds, such as for example with oleyl alcohol, but alcohols derived from saturated fatty acids are preferably used. Examples include: myristyl, palmityl, stearyl, arachyl -, behenyl alcohol and montan wax fatty alcohols.
- the alcohols are preferably used in the form of their technical mixtures in the preparation of the esters, very particularly those technical mixtures of saturated fatty alcohols with 16 to 22 carbon atoms are to be emphasized.
- the other acid residue of the dicarboxylic acid is esterified with a di- or trihydric alcohol, and the remaining hydroxyl groups can also be etherified.
- Such alcohols - as can be seen from the formula scheme of the general formula (I) - are ethylene, 1,2-propylene and 1,2-butylene and 1,4-butylene and 1,6-hexylene glycol Consider, where the still free hydroxyl group can be etherified with a monohydric alcohol having 1 to 4 carbon atoms.
- the di- and triethylene or propylene glycol and the glycerin are also suitable. Ethylene glycol and glycerin are particularly preferred as the second esterification component.
- the asymmetrical diesters are prepared in a manner known per se by reacting the dicarboxylic acid or a derivative thereof, such as the acid chloride or - if accessible - the anhydride with the long-chain monohydric alcohol in a molar ratio of 1: about 1 and then further reacting in a known manner with the optionally diol or triol etherified on one side.
- the corresponding alkylene oxides can also be used, as described, for example, in British Pat. No. 1,162,898. It is sufficient to drive the reaction to an acid number below 30 (including the small amount of esterification catalyst).
- the production of the asymmetrical diester is particularly simple if one starts from the anhydrides, in particular the maleic anhydride, as far as is accessible, which is why these are preferred as the starting material for the production of the diesters.
- the asymmetrical diesters thus produced are converted into aqueous emulsions individually, but also in a mixture with one another, using emulsifiers in a known manner.
- Anionic, nonionic and cationic can be used as emulsifiers.
- Nonionic and cationic, optionally in a mixture with one another, are preferably used, since emulsions prepared with the aid of such emulsifiers are generally compatible with other products known for textile finishing.
- the emulsifiers are used in customary amounts of 4 to 30% by weight, in particular 8 to 25% by weight (calculated as solid substance based on the asymmetrical diester).
- a particular embodiment of the invention consists in using these diester emulsions together with polyethylene.
- the polyethylene emulsions known per se can be mixed with the diester emulsions insofar as the emulsifiers used in each case for producing the emulsions are compatible with one another.

- Anionic, nonionic or cationic emulsifiers for emulsifying the polyethylene in known amounts are also suitable, as reported for example by G. Louis and co-workers (Textilveredlung 2 (1967), page 400/401).
- the joint emulsification of a melted mixture of diester and polyethylene is more advantageous than the subsequent mixing of the pre-formed diester and polyethylene emulsions. This shows that the melting point depression that occurs makes it much easier for the polyethylene in the mixture with the diester to emulsify than the polyethylene alone.
- the sequential emulsification of the molten polyethylene and the molten diester is also very suitable.
- the emulsions of the mixtures are less viscous than the emulsions of the pure diester at the same solids content, which is often desirable.
- the use of the emulsions of the mixtures of diester and polyethylene has the advantage that the handle, the wet soiling and the "soil release" properties give the treated fiber material an improvement in tear and abrasion resistance as well as sewability.
- the proportion of diester, based on the sum of diester and polyethylene, should, however, be at least 25% by weight, preferably at least 35% by weight, since otherwise significant losses in terms of the achievable positive properties have to be accepted.
- the emulsions are usually prepared so that they have a solids content of this or of diesters and polyethylene of about 15 to 40% by weight.
- the emulsions according to the invention can be used very universally for softening fiber material, in particular textile material, since - depending on the intended use - they can be adjusted anionically, cationically or nonionically. In this way, they can be combined with other products that are customary for the treatment of fiber material.

- the individual treatment methods are familiar to the person skilled in the art; in addition to the usual padding process, they also include coating the Fiber material, optionally in a foamed form.
- the treatment with the emulsions according to the invention is suitable for all types of fiber materials.
- the fiber materials are leather, leather substitutes, paper made from the usual fiber materials and in particular textiles, the latter in the form of woven fabrics, knitted fabrics and optionally pre-consolidated nonwovens.
- the textile material can consist of natural fibers such as those made of cellulose or wool or of synthetic fibers such as polyester, polyamide or polyacrylic fibers.
- textile material made of natural and synthetic fibers can of course also be treated.
- test specimens are treated for 20 minutes at 60 ° C. with constant agitation (liquor ratio 1:50), then rinsed once, half of the
- the reaction product is a Has an acid number of 20 or lower, the reaction is terminated, which is the case after about 1 to 1 1/2 hours.

Sie enthalten außer einem Emulgator oder Emulgatorsystem als Weichgriffmittel ausgewählte, unsymmetrische Diester von bestimmten Dicarbonsäuren.

Die Verwendung von Polyethylen-Emulsionen zur Textilbehandlung ist seit langem bekannt, wie z.B. aus der Veröffentlichung von F. Schrum und L.Quenn (Amer. Dyest.The use of polyethylene emulsions for textile treatment has long been known, e.g. from the publication by F. Schrum and L.Quenn (Amer. Dyest.
Rep. 56 (1967), Seite 924 bis 927) hervorgeht. Diese Emulsionen verleihen den damit behandelten Textilien, besonders bei ihrer gemeinsamen Anwendung mit die Knitterfestigkeit steigernden Produkten, eine verbesserte Einreiß- und Scheuerfestigkeit sowie Vernähbarkeit verbunden mit einem weichen Warengriff.Rep. 56 (1967), pages 924 to 927). These emulsions give the textiles treated with them, especially when used together with products that increase the creasing resistance, improved tearing and abrasion resistance and sewability tied with a soft handle.
Doch lassen die zum Stande der Technik gehörenden Polyethylen-Emulsionen insbesondere hinsichtlich des Griffes sowie der Naßanschmutzung noch zu wünschen übrig.However, the polyethylene emulsions belonging to the prior art still leave something to be desired, particularly with regard to the handle and the wet soiling.
Aufgabe der vorliegenden Erfindung ist die Bereitstellung von Weichmacher-Emulsionen für Fasermaterial, insbesondere Textilmaterial, die die aufgezeigten Nachteile bei ihrer Anwendung nicht zeigen.The object of the present invention is to provide plasticizer emulsions for fiber material, in particular textile material, which do not show the disadvantages shown when they are used.
Die Aufgabe wird durch die Bereitstellung von wäßrigen Emulsionen zum Weichmachen von Fasermaterial, insbesondere von Textilmaterial gelöst, die mindestens einen Emulgator, mindestens ein Weichgriffmittel und weitere übliche Bestandteile enthalten, das dadurch gekennzeichnet ist, daß die Emulsion als Weichgriffmittel mindestens einen Diester einer Dicarbonsäure der allgemeinen Formel (I)

bedeuten, enthält.The object is achieved by the provision of aqueous emulsions for softening fiber material, in particular textile material, which contain at least one emulsifier, at least one softening agent and other customary constituents, which is characterized in that the emulsion as softening agent comprises at least one diester of a dicarboxylic acid of the general type Formula (I)

- m = 0, 1 or 2 and
- n = 2 or 3
mean contains.
Außerdem wird ein Verfahren zum Weichmachen von Fasermaterial, insbesondere von Textilmaterial mit den erfindungsgemäßen Emulsionen beansprucht.A method for softening fiber material, in particular textile material, with the emulsions according to the invention is also claimed.
Wie aus dem Formelschema der allgemeinen Formel (I) hervorgeht, liegen den Diestern als Dicarbonsäure die Bernstein-, Glutar-, Adipin- sowie die Fumar- und insbesondere die Maleinsäure zugrunde. Letztere ist aus wirtschaftlichen Überlegungen heraus besonders bevorzugt, doch lassen sich generell die unsymmetrischen Diester besonders gut aus den Anhydriden herstellen, weshalb allen ein Anhydrid bildenden Säuren besondere Bedeutung zukommt.As can be seen from the formula scheme of the general formula (I), the diesters as dicarboxylic acid are based on succinic, glutaric, adipic and fumaric and in particular maleic acid. The latter is particularly preferred for economic reasons, but in general the asymmetrical diesters can be produced particularly well from the anhydrides, which is why all acids forming an anhydride are of particular importance.
Der eine Säurerest der Dicarbonsäure ist mit einem einwertigen Alkohol mit 12 bis 28 C-Atomen verestert.Diese Alkohole können, wie z.B. beim Oleylalkohol, Doppelbindungenerthalten, bevorzugt werden jedoch Alkohole, die sich von gesättigten Fettsäuren ableiten, verwendet. Beispielhaft seien genannt: Myristyl-, Palmityl-, Stearyl-, Arachyl-, Behenylalkohol und Montanwachsfettalkohole. Vorzugsweise werden bei der Herstellung der Ester die Alkohole in Form ihrer technischen Mischungen eingesetzt, wobei ganz besonders die technischen Gemische von gesättigten Fettalkoholen mit 16 bis 22 C-Atomen hervorzuheben sind.One acid residue of the dicarboxylic acid is esterified with a monohydric alcohol having 12 to 28 carbon atoms. These alcohols can contain double bonds, such as for example with oleyl alcohol, but alcohols derived from saturated fatty acids are preferably used. Examples include: myristyl, palmityl, stearyl, arachyl -, behenyl alcohol and montan wax fatty alcohols. The alcohols are preferably used in the form of their technical mixtures in the preparation of the esters, very particularly those technical mixtures of saturated fatty alcohols with 16 to 22 carbon atoms are to be emphasized.
Der andere Säurerest der Dicarbonsäure ist mit einem zwei- oder dreiwertigen Alkohol verestert, wobei die verbleibenden HydroxyLgruppen auch verethert sein können. Als solche Alkohole kommen - wie aus dem Formelschema der allgemeinen Formel (I) ersichtlich - das Ethylen-, das 1,2-Propylen- und 1,2-Butylen- sowie das 1,4-Butylen-und 1,6-Hexylenglykol in Betracht, wobei die noch freie Hydroxylgruppe mit einem einwertigen Alkohol mit 1 bis 4 C-Atomen verethert sein kann. Darüber hinaus sind auch das Di- und Triethylen- bzw. -propylenglykol sowie das Glycerin geeignet. Besonders bevorzugt sind als zweite Veresterungskomponente das Ethylenglykol und das Glycerin.The other acid residue of the dicarboxylic acid is esterified with a di- or trihydric alcohol, and the remaining hydroxyl groups can also be etherified. Such alcohols - as can be seen from the formula scheme of the general formula (I) - are ethylene, 1,2-propylene and 1,2-butylene and 1,4-butylene and 1,6-hexylene glycol Consider, where the still free hydroxyl group can be etherified with a monohydric alcohol having 1 to 4 carbon atoms. In addition, the di- and triethylene or propylene glycol and the glycerin are also suitable. Ethylene glycol and glycerin are particularly preferred as the second esterification component.
Die Herstellung der unsymmetrischen Diester erfolgt in an sich bekannter Weise durch Umsetzung der Dicarbonsäure oder einem Derivat derselben, wie dem Säurechlorid oder - soweit zugänglich - dem Anhydrid mit dem langkettigen einwertigen Alkohol im Molverhältnis 1 : etwa 1 und anschließender weiterer Umsetzung in bekannter Weise mit dem gegebenenfalls einseitig veretherten Di- bzw. Triol. Anstelle der Polyole können auch die entsprechenden Alkylenoxide eingesetzt werden, wie es beispielsweise in der GB-PS 1 162 898 beschrieben ist. Es ist ausreichend, die Umsetzung soweit zu treiben, daß eine Säurezahl von unter 30 (einschließlich der geringen Menge an Veresterungskatalysator) erreicht wird.The asymmetrical diesters are prepared in a manner known per se by reacting the dicarboxylic acid or a derivative thereof, such as the acid chloride or - if accessible - the anhydride with the long-chain monohydric alcohol in a molar ratio of 1: about 1 and then further reacting in a known manner with the optionally diol or triol etherified on one side. Instead of the polyols, the corresponding alkylene oxides can also be used, as described, for example, in British Pat. No. 1,162,898. It is sufficient to drive the reaction to an acid number below 30 (including the small amount of esterification catalyst).
Besonders einfach gestaltet sich die Herstellung des unsymmetrischen Diesters, wenn man - soweit zugänglich - von den Anhydriden, insbesondere dem Maleinsäureanhydrid ausgeht, weshalb diese als Ausgangsmaterial für die Herstellung der Diester bevorzugt sind.The production of the asymmetrical diester is particularly simple if one starts from the anhydrides, in particular the maleic anhydride, as far as is accessible, which is why these are preferred as the starting material for the production of the diesters.
Die so hergestellten unsymmetrischen Diester werden einzeln aber auch in Mischung untereinander mit Hilfe von Emulgatoren in bekannter Weise in wäßrige Emulsionen überführt. Als Emulgatoren kommen anionische, nichtionische und kationische in Betracht. Bevorzugt werden nichtionische und kationische, gegebenenfalls in Mischung untereinander eingesetzt, da mit Hilfe solcher Emulgatoren hergestellte Emulsionen in der Regel mit anderen zur Textilveredelung bekannten Produkten verträglich sind.The asymmetrical diesters thus produced are converted into aqueous emulsions individually, but also in a mixture with one another, using emulsifiers in a known manner. Anionic, nonionic and cationic can be used as emulsifiers. Nonionic and cationic, optionally in a mixture with one another, are preferably used, since emulsions prepared with the aid of such emulsifiers are generally compatible with other products known for textile finishing.
Als Beispiele für Emulgatoren seien genannt:
- Polyvinylalkohol in wäßriger Lösung, ethoxylierte Fettsäureamide, ethoxylierte Fettsäuren, ethoxylierte Fettalkohole und ethoxylierte Fettamine, letztere auch in Form ihrer Salze mit niedermolekularen organischen Säuren oder Mineralsäuren sowie quaternäre Ammoniumverbindungen wie Octadeyloxymethylpyridiniumchlorid oder Cetylbenzyldimethylammoniumehlorid. Ebenfalls als Emulgatoren geeignet sind Umsetzungsprodukte aus Epoxygruppen enthaltenden Verbindungen und Di- oder Polyaminen, wie sie z.B. in der US-PS 3 320 197 beschrieben sind, oder Kondensationsprodukte aus Harnstoff und seinen Derivaten mit Epoxygruppen enthaltenden Verbindungen und ausgewählten Aminen, wie sie in der US-PS 3 729 437 besehrieben sind. Besonders bewährt haben sich als Emulgatoren Polyglykoletherreste enthaltende Fettsäureamide, wie sie aus der US-PS 3 904 661 bekannt sind, da diese oberflächenaktiven Substanzen schwach kationaktive Eigenschaften mit nichtionischen Eigenschaften in sich vereinen.
- Polyvinyl alcohol in aqueous solution, ethoxylated fatty acid amides, ethoxylated fatty acids, ethoxylated fatty alcohols and ethoxylated fatty amines, the latter also in the form of their salts with low molecular weight organic acids or mineral acids as well as quaternary ammonium compounds such as octadeyloxymethylpyridinium chloride or cetylbenzyldimethylammonium chloride. Also suitable as emulsifiers are reaction products of compounds containing epoxy groups and di- or polyamines, as described, for example, in US Pat. No. 3,320,197, or condensation products of urea and its derivatives with compounds containing epoxy groups and selected amines, as described in the US -PS 3 729 437 are described. Fatty acid amides containing polyglycol ether residues, as are known from US Pat. No. 3,904,661, have proven particularly useful as emulsifiers, since these surface-active substances combine weakly cationic properties with nonionic properties.
Die Emulgatoren werden dabei in üblichen Mengen von 4 bis 30, insbesondere 8 bis 25 Gewichts-% (gerechnet als Festsubstanz bezogen auf den unsymmetrischen Diester) eingesetzt.The emulsifiers are used in customary amounts of 4 to 30% by weight, in particular 8 to 25% by weight (calculated as solid substance based on the asymmetrical diester).
Wie schon erwähnt, besteht eine besondere Ausgestaltung der Erfindung darin, diese Diester-Emulsionen zusammen mit Polyethylen einzusetzen. Dabei können die an sich bekannten Polyethylenemulsionen mit den Diester-Emulsionen vermischt werden, soweit die jeweils zur Herstellung der Emulsionen verwendeten Emulgatoren miteinander verträglich sind.As already mentioned, a particular embodiment of the invention consists in using these diester emulsions together with polyethylene. The polyethylene emulsions known per se can be mixed with the diester emulsions insofar as the emulsifiers used in each case for producing the emulsions are compatible with one another.
In der Textilindustrie werden vor allem sogenannte Sekundäremulsionen eingesetzt; das sind solche, die durch Emulgierung von Polyethylen, das reaktive Gruppen enthält, erhalten werden. Dabei kommen ebenfalls anionische, nichtionogene oder kationische Emulgatoren zur Emulgierung des Polyethylens in bekannten Mengen in Betracht, wie beispielsweise von G. Louis und Mitarbeiter (Textilveredlung 2 (1967), Seite 400/401) berichtet wird.So-called secondary emulsions are mainly used in the textile industry; these are those obtained by emulsifying polyethylene containing reactive groups. Anionic, nonionic or cationic emulsifiers for emulsifying the polyethylene in known amounts are also suitable, as reported for example by G. Louis and co-workers (Textilveredlung 2 (1967), page 400/401).
Vorteilhafter als die nachträgliche Vermischung der vorgebildeten Diester- und Polyethylen-Emulsionen ist die gemeinsame Emulgierung einer aufgeschmolzenen Mischung aus Diester und Polyethylen. Hierbei zeigt sich, daß sich durch die eintretende Schmelzpunktsdepression das Polyethylen in der Mischung mit dem Diester wesentlich leichter emulgieren läßt als das Polyethylen allein. Ebenfalls sehr gut geeignet ist die aufeinanderfolgende Emulgierung des geschmolzenen Polyethylens und des geschmolzenen Diesters. Die Emulsionen der Mischungen sind bei gleichem Feststoffgehalt weniger viskos als die Emulsionen des reinen Diesters, was häufig erwünscht ist.The joint emulsification of a melted mixture of diester and polyethylene is more advantageous than the subsequent mixing of the pre-formed diester and polyethylene emulsions. This shows that the melting point depression that occurs makes it much easier for the polyethylene in the mixture with the diester to emulsify than the polyethylene alone. The sequential emulsification of the molten polyethylene and the molten diester is also very suitable. The emulsions of the mixtures are less viscous than the emulsions of the pure diester at the same solids content, which is often desirable.
Die Anwendung der Emulsionen der Mischungen aus Diester und Polyethylen hat den Vorteil, daß ohne nennenswerte Beeinträchtigung des Griffes, der Naßanschmutzung und der "Soil-Release"-Eigenschaften dem behandelten Fasermaterial gleichzeitig eine Verbesserung der Reiß- und Scheuerfestigkeit sowie der Vernähbarkeit verliehen wird.The use of the emulsions of the mixtures of diester and polyethylene has the advantage that the handle, the wet soiling and the "soil release" properties give the treated fiber material an improvement in tear and abrasion resistance as well as sewability.
Der Anteil an Diester, bezogen auf die Summe von Diester und Polyethylen, sollte jedoch mindestens 25 Gewichts-%, bevorzugt mindestens 35 Gewichts-% betragen, da anderenfalls nennenswerte Einbußen hinsichtlich der erzielbaren positiven Eigenschaften hinzunehmen sind.The proportion of diester, based on the sum of diester and polyethylene, should, however, be at least 25% by weight, preferably at least 35% by weight, since otherwise significant losses in terms of the achievable positive properties have to be accepted.
Die Emulsionen werden dabei in der Regel so hergestellt, daß sie einen Feststoffgehalt an Dieser bzw. an Diester und Polyethylen von ca. 15 bis 40 Gewichts-% aufweisen.The emulsions are usually prepared so that they have a solids content of this or of diesters and polyethylene of about 15 to 40% by weight.
Die erfindungsgemäßen Emulsionen können zum Weichmachen von Fasermaterial, insbesondere von Textilmaterial sehr universell eingesetzt werden, da sie - je nach dem vorgesehenen Verwendungszweck - anionisch, kationisch oder nichtionisch eingestellt werden können. So können sie mit anderen zur Behandlung von Fasermaterial üblichen Produkten kombiniert werden. Besonders hervorgehoben sei für den Bereich der Behandlung von Textilmaterial die Kombination mit Produkten, die die Knitterfestigkeit verbessern, Produkten zur Erzielung einer Wasser- und bzw. oder Ölabweisung und Produkten zum Flammhemmendmachen, wobei hierzu selbstverständlich auch die entsprechenden Katalysatoren zu zählen sind.The emulsions according to the invention can be used very universally for softening fiber material, in particular textile material, since - depending on the intended use - they can be adjusted anionically, cationically or nonionically. In this way, they can be combined with other products that are customary for the treatment of fiber material. For the treatment of textile material, special mention should be made of the combination with products that improve the creasing resistance, products for achieving water and / or oil repellency and products for flame retardancy, which of course also includes the corresponding catalysts.
Von den erfindungsgemäßen Emulsionen kommen in Abhängigkeit der Konzentration, des zu behandelnden Fasermaterials und der Behandlungsmethode jeweils ca. 10 g/1 bis 80 g/1 zum Einsatz. Die einzelnen Behandlungsmethoden sind dem Fachmann geläufig; sie umfassen neben dem üblichen Foulardverfahren auch das Beschichten des Fasermaterials, gegebenenfalls in verschäumter Form.Depending on the concentration, the fiber material to be treated and the treatment method, approx. 10 g / 1 to 80 g / 1 of the emulsions according to the invention are used. The individual treatment methods are familiar to the person skilled in the art; in addition to the usual padding process, they also include coating the Fiber material, optionally in a foamed form.
Zur Erzielung der erwünschten Effekte genügt es, das behandelte Fasermaterial bei etwa 70°C bis 1200C zu trocknen, sofern nicht die kombiniert mit angewandten Produkte ein höheres Erhitzen erfordern. Bei solchen zusätzlich angewandten Produkten, sei es zur Verbesserung der Knitterfestigkeit, der Hydrophobierung und der Flammfestigkeit, sind in der Regel für 1 bis 8 Minuten Temperaturen von 130°C bis 170°C erforderlich.To achieve the desired effects, it is sufficient to dry the treated fiber material at about 70 ° C to 120 0 C, provided that the combined require products with applied a higher heating. With such additionally used products, be it to improve the creasing resistance, the hydrophobization and the flame resistance, temperatures of 130 ° C. to 170 ° C. are generally required for 1 to 8 minutes.
Die Behandlung mit den erfindungsgemäßen Emulsionen ist für Fasermaterialien aller Art geeignet. Als Fasermaterialien sind Leder, Lederersatzstoffe, Papier aus den üblichen Fasermaterialien und insbesondere Textilien zu nennen, letztere in Form von Geweben, Gewirken und gegebenenfalls vorverfestigten Faservliesen. Das Textilmaterial kann dabei aus natürlichen Fasern wie solchen aus Cellulose oder Wolle oder aus Synthesefasern, wie aus Polyester-, Polyamid- oder Polyacryl-fasern, bestehen. Daneben kann selbstverständlich auch Textilmaterial behandelt werden, das aus natürlichen und synthetischen Fasern hergestellt worden ist.The treatment with the emulsions according to the invention is suitable for all types of fiber materials. The fiber materials are leather, leather substitutes, paper made from the usual fiber materials and in particular textiles, the latter in the form of woven fabrics, knitted fabrics and optionally pre-consolidated nonwovens. The textile material can consist of natural fibers such as those made of cellulose or wool or of synthetic fibers such as polyester, polyamide or polyacrylic fibers.
