Abstract
Description
Zur Herstellung wasserdichter Leder oder Pelze sind insbesondere drei Verfahrensprinzipien bekannt:
- 1) Imprägnierung durch Einlagerung wasserunlöslicher Substanzen, z.B. feste Fette, Wachse oder spezielle Polymere.
- 2) Imprägnierung durch Einlagerung wasserquellender Substanzen, die bei Wasseraufnahme hochviskose Emulsionen bilden und die Faserzwischenräume des Leders verstopfen, z. B. spezielle Emulgatoren vom Wasser-in-Ö!-(W/0)-Typ.
- 3) Behandlung mit hydrophobierend wirkenden Substanzen, z. B. Aluminium- und Chromkomplexe, Silikone oder organische Fluor-Verbindungen.
- 1) Impregnation by storing water-insoluble substances, e.g. solid fats, waxes or special polymers.
- 2) Impregnation by embedding water-swelling substances that form highly viscous emulsions when water is absorbed and clog the interstices of the leather, e.g. B. special emulsifiers of the water-in-oil! (W / 0) type.
- 3) Treatment with hydrophobizing substances, e.g. B. aluminum and chromium complexes, silicones or organic fluorine compounds.
Diese Maßnahmen können auch im Zusammenhang mit einer üblichen Lickerung unter Verwendung gebräuchlicher Fettungsmittel durchgeführt, wobei die genannten Mittel in der Lickerflotte eingesetzt werden.These measures can also be carried out in connection with a conventional seepage using customary degreasing agents, the agents mentioned being used in the seepage liquor.
In der Praxis wird häufig eine Kombination der unter 2) und 3) genannten Maßnahmen angewandt, wobei aus wirtschaftlichen und ökologischen Gründen bevorzugt im Walkfaß in wäßriger Flotte gearbeitet wird. Dabei erfolgt eine Umwandlung der W/O-Emulgatoren in hydrophobierende Metallkomplexsalze durch eine Fixierung mit Chrom- bzw. Aluminiumsalzen. Dieses Verfahren weist aber Nachteile auf, da wegen der Instabilität der gebräuchlichen Lickeremulsionen die Imprägnierung bei relativ hohen pH-Werten (>6) durchgeführt werden muß, um ein oberflächliches Ausfallen der Fettungsmittel und damit Verschmierungen zu vermeiden. Außerdem ist bei diesem Verfahren in der Regel eine hohe Temperatur der Lickerflotte von ca. 60°C erforderlich, was leicht zu einer Losnarbigkeit des Leders führt. Außerdem zeigen die in der praxis erhaltenen Penetrometerwerte häufig starke Schwankungen infolge einer ungleichmäßigen Fettverteilung durch den Lederquerschnitt, so daß eine aufwendige Nachbehandlung des Leders durch Spritzen, Gießen oder Plüschen notwendig werden kann.In practice, a combination of the measures mentioned under 2) and 3) is often used, with work being carried out preferably in a drum in an aqueous liquor for economic and ecological reasons. The W / O emulsifiers are converted into hydrophobizing metal complex salts by fixation with chromium or aluminum salts. However, this method has disadvantages, since, due to the instability of the usual licker emulsions, the impregnation must be carried out at relatively high pH values (> 6) in order to avoid superficial precipitation of the greasing agents and thus smearing. In addition, this process generally requires a high temperature of the licker liquor of approximately 60 ° C., which easily leads to a loose grain of the leather. In addition, the penetrometer values obtained in practice often show large fluctuations as a result of an uneven fat distribution through the leather cross section, so that an expensive aftertreatment of the leather by spraying, pouring or plushing may be necessary.
Eine Stabilisierung der Lickerflotte mit anionischen und nichtionischen Emulgatoren, wie Alkylsulfaten, Alkylarylsulfonaten oder Fettalkoholethoxylaten kommt wegen der Erhöhung der Wasserzügigkeit nicht in Frage.Stabilizing the licker liquor with anionic and nonionic emulsifiers, such as alkyl sulfates, alkylarylsulfonates or fatty alcohol ethoxylates, is out of the question because of the increase in water absorbency.
Aus DE-OS-1 669 347 ist die Anwendung von in Wasser emulgierbaren Sulfobernsteinsäureestern zum Fetten von Leder bekannt, wobei jedoch keine Wasserdichteffekte erzielt werden.DE-OS-1 669 347 discloses the use of water-emulsifiable sulfosuccinic acid esters for greasing leather, but no waterproofing effects are achieved.
In EP-A-0 165 481 wird ein Verfahren zur Herstellung von Leder und Pelzen beschrieben, wobei als Fettungsmittel in der Gerbflotte eine Kombination von Sulfobernsteinsäureestern mit bestimmten anionischen oder nichtionischen Emulgatoren während der Chrom- oder Aluminiumgerbung bzw. -Nachgerbung angewendet wird. Auch bei diesem Verfahren wird ein Wasserdichteffekt nicht erzielt.EP-A-0 165 481 describes a process for the production of leather and furs, a combination of sulfosuccinic acid esters with certain anionic or nonionic emulsifiers during chrome or aluminum tanning or retanning being used as the fatliquor in the tanning liquor. A waterproof effect is not achieved with this method either.
Es wurde nun die überraschende Feststellung gemacht, daß mit Sulfobernsteinsäuremonoestern gefettete Leder bei hoher Weichheit eine verminderte Wasserzügigkeit aufweisen, wenn nach dem Absäuern der Fettung eine Fixierung mit Chrom- und/oder Aluminiumsalzen vorgenommen wird.It has now been made the surprising finding that leather greased with sulfosuccinic acid monoesters, with high softness, has a reduced water absorbency if fixation with chromium and / or aluminum salts is carried out after acidification of the greasing.
Damit ist es möglich, unter Mitverwendung von Sulfobernsteinsäuremonoestern bei der imprägnierenden und/oder hydrophobierenden Fettung die Stabilität der Lickeremulsionen so zu verbessern, daß die beschriebenen Nachteile der bisherigen Verfahren nicht auftreten.It is thus possible, with the use of sulfosuccinic acid monoesters in the impregnating and / or hydrophobic greasing, to improve the stability of the licker emulsions in such a way that the disadvantages of the previous processes described do not occur.
Gegenstand der Erfindung ist somit ein Verfahren zur Herstellung wasserdichter Leder oder Pelze unter Verwendung von Sulfobernsteinsäuremonoestern in Kombination mit imprägnierenden und/oder hydrophobierenden Fettungsmitteln, dadurch gekennzeichnet, daß man die Leder oder Pelze im Anschluß an die Nachgerbung in wäßriger Flotte mit imprägnierenden und/oder hydrophobierenden Fettungsmitteln, die Sulfobernsteinsäuremonoester-Salze mit C12-C24-Fettresten enthalten, behandelt und nach Absäuern durch Zugabe eines Chrom- und/oder Aluminiumsalzes fixiert.The invention thus relates to a process for the production of waterproof leather or furs using sulfosuccinic acid monoesters in combination with impregnating and / or hydrophobizing greasing agents, characterized in that the leather or furs are subsequently impregnated in an aqueous liquor with impregnating and / or hydrophobizing agents Fatting agents that contain sulfosuccinic acid monoester salts with C 12 -C 24 fat residues, treated and fixed after acidification by adding a chromium and / or aluminum salt.
Die Sulfobernsteinsäuremonoester-Salze werden vorzugsweise in Kombination mit imprägnierenden Fettungsmitteln angewendet. Hierzu zählen insbesondere oxidierte oder oxidierte und teilsulfierte C18-C26-Kohlenwasserstoffe oder C32-C4O-Wachse, PhosphorsäuremonO-C12-C24-alkylester, Partialester von Polycarbonsäuren, wie Citronensäureniono-C,6-C24-alkylester, Partialester von Polyalkoholen, wie Sorbitan-, Glyzerin- oder Pentaerythrit-C16-C24-fettsäureester.The sulfosuccinic acid monoester salts are preferably used in combination with impregnating fatliquoring agents. These include, in particular, oxidized or oxidized and partly sulfonated C 18 -C 26 hydrocarbons or C 32 -C 4 O waxes, Phosphorsäuremon O C 12 -C 24 -alkyl esters, partial esters of polycarboxylic acids such as Citronensäureniono-C 6 -C 24 -alkyl Partial esters of polyalcohols, such as sorbitan, glycerol or pentaerythritol C 16 -C 24 fatty acid esters.
In der Fettungsmittel-Kombination beträgt der Anteil der Sulfobernsteinsäuremonoester-Salze 10 bis 60, vorzugsweise 20 bis 40 Gewichtsprozent. Derartige Fettungsmittel werden bei der Lickerfettung je nach Ledertyp in einer Menge von 5 bis 20 Gewichtsprozent, bezogen auf das Falzgewicht der Leder, eingesetzt.The proportion of sulfosuccinic acid monoester salts in the fatliquor combination is 10 to 60, preferably 20 to 40 percent by weight. Such greasing agents are used in licker lubrication, depending on the type of leather, in an amount of 5 to 20 percent by weight, based on the shaved weight of the leather.
Bei Verwendung der Sulfobernsteinsäuremonoester in Kombinationen mit Neutralölen, wie langkettige Kohlenwasserstoffe, Chlorparaffin, tierische und vegetabile Öle und Fette bzw. deren Methylester und chlorierte Fettsäuremethylester, als Fettungsmittel tritt ebenfalls eine verminderte Wasserzügigkeit der Leder ein, wenn nach der Fettung abgesäuert und danach mit Chrom- und/oder Aluminiumsalzen fixiert wird.When the sulfosuccinic acid monoesters are used in combinations with neutral oils, such as long-chain hydrocarbons, chlorinated paraffin, animal and vegetable oils and fats or their methyl esters and chlorinated fatty acid methyl esters, the leather also has a reduced water absorbency if acidified after greasing and then with chromium and / or aluminum salts is fixed.
Die genannten Sulfobernsteinsäuremonoester-Salze enthaltenden Fettungsmittel können auch anteilig in einer normalen Lickerfettung mit sulfatierten, sulfitierten und/oder synthetischen Fettungsmitteln auf Basis Chlorparaffinsulfonaten mitverwendet werden, wobei je nach Anteil der imprägnierenden und/oder hydrophobierenden Fettungsmittel eine mehr oder weniger stark ausgeprägte Wasserdichtigkeit erzielt wird.The above-mentioned fatty agents containing sulfosuccinic acid monoester salts can also be used in part in normal leaching with sulfated, sulfited and / or synthetic fatliquors based on chloroparaffin sulfonates, depending on the proportion of impregnating and / or hydrophobizing fatliquoring, a more or less pronounced water resistance is achieved.
Die Herstellung der Sulfobernsteinsäuremonoester-Salze erfolgt in bekannter Weise durch Veresterung von Maleinsäureanhydrid mit ca. einem Äquivalent der gewünschten Veresterungskomponente und anschließende Umsetzung mit einer dem Maleinsäureanhydrid annähernd äquivalenten Menge eines Sulfits oder Bisulfits, z. B. entsprechend DE-OS-1 669 347. Als Veresterungskomponente kommen Fettreste mit 12 bis 24 C-Atomen sowie Hydroxygruppen enthaltende Verbindungen in Betracht. Die Fettreste können gesättigt oder ungesättigt sein. Sie können sich herleiten von Fettalkoholen oder Fettsäuremono- oder -diglyceriden, z. B. C12-C18-Kokosfettalkohol, C16-C18 -Talgalkohol, C16-C18-Talgfettsäuremonoglycerid, oder von Addukten von 1 bis 6 Mol Alkylenoxid an die genannten Fettalkohole oder Fettsäureglyceride oder an Fettsäuren, z. B. das Addukt von 2 bis 3 Mol Ethylenoxid an C16-C18-Talgfettalkohol oder von 4 bis 6 Mol Ethylenoxid an ein C16-C24-Fettsäregemisch oder von 2 Mol Ethylenoxid an ein C12-C18-Fettsäuregemisch. Die Sulfobernsteinsäuremonoester-Salze werden vorzugsweise als Natrium- oder Ammoniumsalze hergestellt, doch kommen als Kationen auch andere Alkalien oder organische Amine in Betracht.The sulfosuccinic acid monoester salts are prepared in a known manner by esterification of maleic anhydride with approximately one equivalent of the desired esterification component and subsequent reaction with an amount of a sulfite or bisulfite approximately equivalent to the maleic anhydride, e.g. B. according to DE-OS-1 669 347. As esterification component fat residues with 12 to 24 carbon atoms and compounds containing hydroxyl groups are suitable. The fat residues can be saturated or unsaturated. They can be derived from fatty alcohols or fatty acid mono- or diglycerides, e.g. B. C 12 -C 18 coconut fatty alcohol, C 16 -C 18 tallow alcohol, C 16 -C 18 tallow fatty acid monoglyceride, or of adducts of 1 to 6 mol of alkylene oxide to the fatty alcohols or fatty acid glycerides mentioned or to fatty acids, for. B. the adduct of 2 to 3 moles of ethylene oxide with C 16 -C 18 tallow fatty alcohol or from 4 to 6 moles of ethylene oxide with a C 16 -C 24 fatty acid mixture or of 2 moles of ethylene oxide with a C 12 -C 18 fatty acid mixture. The sulfosuccinic acid monoester salts are preferably prepared as sodium or ammonium salts, but other alkalis or organic amines can also be used as cations.

Die Nachbehandlung erfolgt zunächst in üblicher Weise durch Absäuern, vorzugsweise mit Ameisensäure, wobei gegebenenfalls eine kurze Behandlung mit einem Polyacrylat-Gerbstoff vorgeschaltet werden kann. Danach erfolgt Fixierung mit den Chrom- und/oder Aluminiumsalzen bei etwa pH 3,5.The claimed process is carried out in such a way that the sulfosuccinic acid monoester salts and, if appropriate, further fatliquoring agents are used as a licker after the retanning and, if appropriate, dyeing and subsequent washing out of excess tanning agent.
